Title: Ferroelectric liquid crystal element and production of the same
Inventor: YAMAMOTO MASAO
IPC: G02F1/1337
Filed: 1990-01-11
Abstract: PURPOSE:To obtain uniform orientation with small orientation nonuniformity over the whole surface of an element easily at low cost by executing an orientation processing to a liquid crystal support board by rubbing in advance and setting the film thickness of an orientation control film less than a specified value. CONSTITUTION:As a liquid crystal support board 15, a substrate 11 is used while receiving the orientation processing in advance and onto the substrate 11, the polyimid with thickness 200Angstrom  is applied as the orientation control film 13. Since the substrate 11 receiving the orientation processing by rubbing in advance is used for the liquid crystal support board and an orientation control film 13 is applied onto the substrate, difference in the strength of rubbing is reduced in the liquid crystal picture element without executing the orientation processing to the orientation control film 13. Thus, the uniform orientation over the whole surface of the element is easily obtained at low cost.

Title: Controller for extrusion molding machine
Inventor: YODA TETSUYA
IPC: B29C48/92
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To improve an operating efficiency of extrusion molding by measuring a time from a time point of detecting a peak value to a time point of outputting a measurement end weight value by a raw material metering control means, obtaining a take-off speed of a raw material based on the time and regulating the speed. SOLUTION: A raw material metering control means detects and stores a peak value P as a measuring starting weight value, stores a weight value obtained by subtracting a preset measured weight span value L from the measuring starting weight value as a measuring end weight value Qe, and outputs a measuring start signal S. Since the time ti from the time point of outputting the signal S when the value P is detected to the time point of outputting the value Qe is measured and the take-off time of a raw material is obtained based on the time to regulate a thickness of a film, it is not necessary to regulate the thickness of the film by a manual work. Further, even when the material of an amount largely exceeding a supply stop set value is supplied to a raw material metering unit, the control of the thickness of the film can be conducted from an earlier time point.

Title: Heating apparatus
Inventor: YAMAGUCHI SHUICHI
IPC: F25B1/00
Filed: 1990-01-12
Abstract: PURPOSE:To prevent dropping down of room heating capacity due to pressure loss in a refrigerant circulation system by a method wherein a compressor works to supply compressed liquid refrigerant into a liquid refrigerant circulation system for increasing the pressure within the system, so that condensation of gaseous refrigerant in a room unit can be promoted. CONSTITUTION:When pressure loss occurs in piping 14 or 16, circulation of a refrigerant decreases gradually, causing the air temperature at a blow-off part 54 of a room unit 12 to drop down gradually. As a result, the temperature difference between at the blow-off port 54 and at a suction port 56 gets smaller and smaller, and finally reaches a set difference value. Then a difference temperature thermostat 46 provides a detection signal to make a controller 48 provide an operation command to a compressor 30 for a few seconds and a valve opening command to an electromagnetic valve 24. Thus a compressed refrigerant piping 52 is connected to a liquid refrigerant piping 16, so that liquid refrigerant compressed by the compressor 30 is sent into the liquid refrigerant piping 16 through a condenser 32. As a result, the pressure in the liquid refrigerant piping 16 rises, and condensation of gaseous refrigerant in the room unit 12 is promoted. Thus dropping down of room heating capacity due to pressure loss can be prevented.
