Title: Liquid crystal display element
Inventor: MINATO TAKAO
IPC: G09G3/18
Filed: 1987-06-03
Abstract: PURPOSE:To stabilize an image display by impressing an alternating electric field of the oscillation frequency smaller than the oscillation frequency corresponding to a response speed to the chiral smectic C phase exhibited by a ferroelectric liquid crystal held in place between electrodes facing each other for a specified time. CONSTITUTION:A monodomain SmC* phase is formed by utilizing polyimide films 601, 602 of a liquid crystal cell 600, subjecting only the one side to a rubbing treatment, forming a cell gap to about 2.1mum, and sealing the ferroelectric liquid crystal having negative dielectric anisotropy by utilizing interfacial tension at 100 deg.C anisotropy, then slowly cooling the liquid crystal. The frequency to this cell 600 is then slowly and continuously changed fro 600Hz to about 100Hz by the alternating electric field of, for example, 20VPP. Zigzag defects are thereby annihilated and the stabilization of the concentrated part of isolated strains is accelerated, by which the stable image display is executed.

Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To provide a power steering device for vehicles which does not prevent the operation of a steering wheel of a driver even at a time of unusual condition of an electric motor and which can largely improve a controllability (response characteristics) of the electric motor at the time of applying a steering assist power. SOLUTION: In a power steering wheel 10r vehicles, an electric motor 34 connected to a main shaft 12 is held in a rotatable manner with covers 26 and 30. Furthermore, the rotation of the electric motor 34 is prevented by inserting a lock pin 42 into the recessed part 46 in normal cases. At the time of unusual cases, the lock pin 42 is detached from the recessed part 46 so that the rotation of the electric motor 34 can be made possible. Consequently, at the time of the unusual condition of the electric motor 34, the operation of the steering wheel is not prevented. Furthermore, since the rotation shaft 36 does not have an electro-magnetic clutch or the like, the inertia moment is reduced and the control response at the time of the steering assist is improved.

Title: Controlling method for ratio of flow rate between fuel and air in combustion device
Inventor: WATANABE KUNITOSHI
IPC: F23N1/02
Filed: 1979-10-31
Abstract: PURPOSE: To improve the accuracy of control of flow-rate ratio by a method wherein burners are thinned out when the flow rate in the main fuel pipe and the main air pipe lessens and the control of the flow-rate ratio between the fuel and air is performed on the basis of the detected values of the pressure of headers of fuel and air.  
     CONSTITUTION: When the flow rate of the main fuel pipe 1 and the main air pipe 2 is within the range of effective measurement by orifices 5-1 and 5-2, the flow-rate ratio between the fuel and air is controlled according to flow-rate measurment signals obtained from the orifices 5-1 and 5-2. When the flow rate of the main fuel pipe 1 and the main air pipe 2 lessens, a part of the burners 4 in combustion is thinned out and at this time the control of the flow-rate ratio between the fuel and air is performed on the basis of the detected values of the pressure of headers 3-1 and 3-2 of the fuel and air. By this method, even when the flow rate of the main fuel pipe 1 and the main air pipe 2 lessens, the flow rate and pressure for every burner 4 can be maintained at a fixed level or higher and thereby the accuracy of the control of the flow-rate ratio can be improved.

Title: Aluminum electrolytic capacitor
Inventor: KUNUGIHARA HIROSHI
IPC: H01G9/12
Filed: 1990-05-29
Abstract: PURPOSE:To prevent outflow of gas of driving electrolytic solution to the outside even if an abnormal stress is applied by providing the outside of a metallic case with a built-in capacitor element with a separate tubular metallic case with a bottom and by arranging an absorbing material which absorbs driving electrolytic solution in an inner surface thereof. CONSTITUTION:When an overvoltage higher than the rated value is applied to an aluminum electrolytic capacitor, an internal pressure of a metallic case 2 rises, thereby allowing an explosion-proof valve provided to a top board 2a to start and a driving electrolytic solution in the inside thereby ejects. In the process, the driving electrolytic solution is absorbed by an absorbing 8 which is arranged in an inner surface of a separate metallic case 7 positioned in the outside. Since hydrogen gas, etc., escapes outside from a small hole 9 provided to the top board 7a of the metallic case 7, explosion, etc., do not occure. Furthermore, an opening part of the metallic case 7 is curling-sealed; therefore, even if driving electrolytic solution absorbed by the absorbing material 8 is cooled and liquified, the liquified driving electrolytic solution gathers between the metallic case 7 and the metallic case 2. Thereby, driving electrolytic solution does not flow out to the outside of the aluminum electrolytic capacitor.
