Title: Device for supplying mixed gas for foodstuff storage
Inventor: KIMOTO ISAO
IPC: F25D3/12
Filed: 1988-06-29
Abstract: PURPOSE:To hold the freshness of fresh foodstuff and prevent the discoloration thereof by providing a gas supply source which ejects a mixed gas of nitrogen, carbon dioxide and ethylene at a low ejection rate into a foodstuff storage cabinet for storing the fresh foodstuff. CONSTITUTION:Nitrogen, carbon dioxide and ethylene are mixed at the proportion of 60:39:1, and the mixed gas is stored in a container 1 under pressure. When the gas, which is heavier than air, is ejected at a low ejection rate from a nozzle 2 of the container 1 installed near an ice chest 3a disposed in the upper part of a foodstuff storage cabinet 3 into said ice chest 3a, it diffuses in every part of the cabinet 3 as it descends therein. Nitrogen and carbon dioxide in the mixed gas prevent the fresh foodstuff from degrading, fermenting and decomposing, and ethylene prevents same from discoloring. Although the ethylene concentration is outside the combustible range, an addition of a small quantity of argon enhances safety.

Filed: 1989-06-23
Abstract: PURPOSE:To realize the high-accuracy, high-SN, and long-life inertial system by providing a device which varies electrostatic capacity corresponding to gimbals angular displacement and detecting the electrostatic capacity variation by angular modulation. CONSTITUTION:A capacitor 10 has a structure similar to a normal variable capacitor and the effective electrode plate area increases or decreases in proportion to the displacement of a gimbals angle, so the electrostatic capacity between the electrode plate is proportional to the gimbals angular displacement. Then a gyro pick-off capacitor 10 is connected to an LC oscillator 1 and the oscillation frequency of the LC oscillator is varied by the electrostatic capacity variation of the capacitor 10 to impose FM modulation. Then an FM modulator 3 obtains a DC displacement signal from the output and thus the high-accuracy, high-SN, and long-life inertial system can be realized.

Title: Inspection sequence producing device
Inventor: KAYASHIMA KAZUHIRO
IPC: G06F17/50
Filed: 1992-06-18
Abstract: PURPOSE:To reduce calculation and a memory capacity required at the time of calculation and produce a short inspection sequence. CONSTITUTION:An evaluation value which is maximized by outputs of a storage element in an order circuit 1 having various values is defined, and the order circuit 1 is converted into a non-linear analog function. An evaluation value calculating part 15 calculates the evaluation value while a partial differential value calculating part 16 and the evaluation value partial differential value calculating part 16 calculate a value wherein the evaluation value is differentiated by an external input. An external input setting part 17 for maximizing the evaluation value searches for an input for maximizing the evaluation value among these values to obtain an input which leads an optimum state transition for each clock. Then a controllable cost inducing part 6 and a controllability determining part 7 are used to select a controllable signal line at this time, so that an input sequence can be efficiently produced by an external input setting part 8 of the controllable signal line. The above operations are repeated for each clock to produce an optimum inspection sequence. An efficient state transition can be obtained by using the evaluation value for leading many states, and further controllable signal lines are detected while an input sequence for controlling this can be obtained.

Abstract: PURPOSE:To enable the detection of a trace of reducing gas ranging from 1- 100ppm dissolved in water by passing atmospheric air and a compressor air through an air refiner to oxidize a reducing gas present in the air before the passage into water. CONSTITUTION:Atmospheric air, a compressor air and an air packed into a cylinder are passed through an air refiner 1 and refined reducing the concentration of gas such as CO and carbon hydrate affiliated compound gas below 1ppm. The air refiner 1 uses an oxidizing catalyst such as a platinum-supported alumina to convert a reducing gas in the air acting as disturbing gas into CO2 and H2O by oxidation. The air thus refined is introduced into a sampling tank 2 for storing water 5 to be detected in which a reducing gas such as gas and organic solvent dissolved is trapped as a gas body with the refined air and brought into contact with a gas detection element 3 mainly composed of a metal oxide semiconductor. Changes in the electric resistance value of the gas detection element 3 is shown on a display 4.
