  • A microcomputer -based data acquistion system was designed and developed at Michigan State University , USA to conduct field data studies. The system designed for the research carried out used an Apple IIe microcomputer for collecting data on-board the tractor. An AII3 Analog to Digital (A/D_ convertor was chosen to interface each analog signal to the microcomputer. A commercially available Dj TPM II was employed to display information such as an engine speed, ground speed, percent drive wheel slip , distance travelled and area covered per hour. The frequency output from the radar unit was channeled through a frequency to voltage (F/V) convertor , so that AII3 Analog to Digital (A/D) convertor could read it. The fuel consumption was measured using on EMCO pdp-1 fuel flow meter attached to the engine fuel line. The draft of the tillage and other drag equipment was determined using strain gages attached to the drawbar of the tractor. The system was developed to collect the draft and fuel requirements for various farm equipment different kind of soils.

  • Microprocessor의 출현은 전자계산기 구조에 일대혁명을 일으볐으며 최근 몇년간 microcomputer가 세게적인 화제의 초점을 이루고 있고 그 응용은 극히 강력한 기대와 관심을 불러 일으키고 있다. Microcomputer의 가장 큰 특징은 micrs computer 자체가 한 system의 component로 사용될 수 있다는 점이며 application software의 개발여하에 따라 무한한 가능성을 약속해 주고 있다. 본 논문에서는 M6800 application software를 개발하기 위하여 M6800 crossassembler를 작성하였다. M6800은 Motorola에서 개발한 micrs computer로 전세계적으로 가장 널리 사용되고 있는 것 중의 하나이다. 본 논문의 2장의 첫 부분에서는 M6800 assembly language가 소개되고 두번째 부분에서는 cross-assembler의 기본적인 특성이 기술되고 있다.

  • Principles of electron diffraction patterns in transmission electron microscope are described for beginners in terms of reciprocal lattices and Ewald sphere. Analysis of both ring patterns and spot patterns are illustrated with practical examples as well as basic calibrations of TEM. Especially convergent beam electron diffraction method is emphasized for the determination of lattice parameters, microstrains, and thickness of thin foil followed by a review of microcomputer programs for the electron diffraction analyses explained in this paper.

  • Land suitability method has become a standard part of planning analysis at many scales. GIS computer packages have been developed for this purpose. But those are still expensive and hard to learn, and also have limits to extend the results to a landscape design. For the relatively simple tasks and CAD-related works, an application of CAD software for the suitability analysis is very useful and easy to handle. For the purpose, this study develops a technique for suitability analysis, using vector based microcomputer CAD softwares.

  • For the automation of Tackjoo fermentation, a sensor measurable gas production during brewing and a controller were built. The performance tests were carried out at 10 litter Tackjoo fermentor, The sensor was consisted of a transparent acryl cell for bubble formation and photo-interrupter for the detection of bubbles of 0.018ml size. The fermentation controller was fabricated with a single chip microcomputer (MC68705R3) and provided with both the monitoring module of temperature measurement and the valve controling device for the cooling water circulation in coil type heat exchanger. The operation programs were developed and systemized in ROM. With this computer system, the gas production amount and rate were acquired during the Tackjoo fermentation. The fermentation curve based on the gas production rate showed a good agreement with that of alcohol concentration. The maximum rate of gas production was found after 24 hr at $30^{\circ}C$. The correlation equation between the gas production and alcohol concentration was established and used as the control algorithm of the fermentation.

  • For the automation of Koji incubation process, microcomputer based Koji incubation system was built and applied to acquisition of the process variables, and to control of the Koji incubation process. The incubation variables included the relative humidity and Koji weight. And data measured were sent to the microcomputer by the interface device built with MC 6821 PIA. Incubation environment conditions -temperature and humidity- were controlled by the actuation of heater and mist sprayer with on/off signal generated by ASIC program. Aspergillus oryzae as a starter of the Koji and steamed barley as media were used and Koji was successfully manufactured both at $25^{\circ}C,\;70%$ RH and at $27^{\circ}C,\;80%$ RH. During the Koji preperation, the temperature was linearly increased and substrate was consumed stepwise showing 3 steps in the weight loss curve.
