CRTs can survive in the long run for TV applications, because of their realistic reproduction of live images. CRT technology development has to be directed towards form factor, but also attention has to be paid to the form design of sets. The CRT is the only technology allowing a doubly curved screen surface.

A closed form expression for the quality factor of the spiral inductor, methodologically, is presented as a function of the inductance ($L_{ind}$), metal-line width (W), spacing (S), inner and the diameter ($D_i$). For a given inductance, the dependences of quality factor on W, S, and $D_i$ are analyzed, and suggested the design optimization guidelines.

Space is integrated or segment with organic formation by circulation path. It estimates important problem to grasp as factor that promote movement of visitor and space organization without grasping circulation as connection relation about simple space function from these viewpoint, is a thing which this study does not cause confusion to visitor's circulation path through data that analyze form of space connection and visitor's circulation path as quantitative in museum space and layout form that access by easy each unit exhibition grasps what it is. This study does factor grasping for guideline and inspection circulation path of layout by purpose in exhibition space on the basis of analytical result that grasps connection form between exhibition area that grasp laying stress on visitor's movement and appears in space through follow-up survey for circulation path of museum exhibition area. Space connection form that is expose by sequence of investigation and analysis(II) estimates on constituent affecting to visitor's circulation, and these do not speak for all space connection forms at the museum, but may systematize typology about connection form of unit spaces to utilize by indicator pointer of space planning if continue study to various spatial sphere more than hereafter. Unit exhibition area, divide connection form of space by grid and tree and laying stress on this quantitative data by spectator follow-up survey comparison and Estimate that space connection form provides partial basis of judgement for supposition that can promote direction and circulation path about visitor's movement if summarize result of investigation and analysis (III).

In turning the chip may be produced in the form of continuous chip or discontinuous one. Continuous chips produced at high speed machining may hit the newly cut workpiece surface and adversely affect the appearance of the surface finish and may interfere with tool and sometimes induce tool fracture. In this study relationship between AE signal and chip form was experimentally investigated, The experimental results show that types of chip form are possible to be classified from the AE signal using fuzzy logic.

In this paper, by introducing a homogenous kernel of -4-degree, we establish a new Hilbert-type integral inequality with multi-parameter and a best constant factor. As applications, the equivalent form, the reverse forms and some particular results are given correspondingly.

In this paper, the integral operator is used. We give a new Hilbert-type integral inequality, whose kernel is the homogeneous form with degree - $\lambda$ and with three pairs of conjugate exponents and the best constant factor and its reverse form are also derived. It is shown that the results of this paper represent an extension as well as some improvements of the earlier results.

This research presents about an expert estimation method to develop a HEMU Original Form of streamline nose. It has difficult part to check to the thought of the designer. We presented the course to extract the Original Form through the form data base this part. But it is the form to be extract in logical method. It is important both intuitional part and sensual part of designer in the course which the form is developed innovative. We extract the factor of the innovation which the experts consider who a sensual brain activity is special and the experience degree is high. We do the structuring the estimation system. And than, we made the method to apply at the practical affairs.

This paper introduces a study on ship performance in waves to consider the effects of added resistance in the early stage of hull-form design. A ship experiences a loss of speed in actual seaways, hence this study proposes the overall procedure of a new design concept that takes into account the hydrodynamic performance of ship in waves. In the procedure, the added resistance is predicted using numerical methods: slender-body theory and Maruo's far-field formulation, since these methods are efficient in initial design stage, and an empirical formula is adopted for short waves. As computational models, KVLCC2 hull and Supramax bulk carrier are considered, and the results of added resistance and weather factor for test models are discussed. The computational results of vertical motion response and added resistance of KVLCC2 hull are compared with the experimental data. In addition, the sensitivity analysis of added resistance and weather factor for KVLCC2 hull to the variations of ship dimensions are conducted, and the change of the added resistance and propulsion factors after hull form variations are discussed.

The objective of this research is significant because it derives the core competency factors that members of education communities must have in order to form warm education communities through investigating the perception of special education teachers. To achieve this, 352 special education teachers and teachers working at special education institutes were asked to record three of the most important factors out of a total of 18 factors that members of an educational community considered to be required in order to form warm educational communities. IBM SPSS Statistics 23 was used to analyze the collected data. First, in oder to examine the demographic characteristics of the educators surveyed, frequency analysis was conducted. Second, frequency analysis on the factors that special education teachers considered to be most important to form a warm education communities was conducted by teacher experience and type of education institute they worked for. When analyzing the research results of main factors that special education teachers considered to be important by teacher experience and type of education institute they worked for, responsibility was confirmed to be the most important factor. The second most important factor was communication and the third most important factor was responsibility and trust. In summary, the research confirmed that if mutual trust between the members of an education community can be established and if problems can be solved through cooperation and through open communication, and if each member of the community serves their role responsibly, a warm education community can be formed.

In this paper we confirm the disappearance of dynamic lock-in simply by increasing the dither noise magnitude of the ring laser gyroscope by numerical and experimental method. After that, we numerically study the relation between the dither noise forms and scale factor non-linearities by comparing those of the two case outputs which are individually generated by operating with the two types of dither noise forms. The first one is the simple form composed of consecutive alternations of the random increasing and decreasing parts but maximum and minimum dither envelopes are scarcely changeable. And the second one is similar to the first one but maximum and minimum dither envelopes are randomly changable. As a result, we find that the scale factor non-linearity could be improved by the second one. And we confirm those results by experimental measurements.
