Title: Liquid crystal display device and its driving method
Inventor: NAKAJIMA YASUSHI
IPC: G02F1/133
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To obtain a device whose display quality is high by restraining the occurrence of disinclination by covering up an auxiliary capacitance electrode formed along the periphery of a picture element area with a picture element electrode through an insulating film. SOLUTION: A gate line(including a gate electrode 25A) 25 and the auxiliary capacitance electrode 26 are pattern-formed of the same metal material on the front surface of a back transparent base plate 23. The gate insulating film 27 consisting of SiN, for instance, is formed to cover over the base plate 23, the gate line 25 and the electrode 26. In this device, the part of the nearly U-shaped electrode 26 formed along the periphery of the picture element area is covered up with the picture element electrode 29. Thus, electric field formed between the electrodes 26 and 29 is not formed above the electrode 29, so that the orientation of the liquid crystal molecules in the picture element area is not changed by the electric field.

Abstract: PURPOSE:To obtain rapid rise of heating immediately after starting by constituting to control change-over of a cross valve provided among a heater core, water pump and a reservoir tank and control a drive pump by cooling liquid temperature. CONSTITUTION:Cooling liquid temperature is detected by a cooling liquid temperature detecting means 18 and input in a control circuit 23.

Title: Mouse detecting sensitivity converter
Inventor: KANEKO FUKASHI
IPC: G06F3/038
Filed: 1990-06-21
Abstract: PURPOSE:To operate a computer game machine in the same way as a joy stick with use of a mouse by applying no signal to the game machine before the moved variable of the mouse exceeds a fixed distance. CONSTITUTION:No movement information on a mouse 3 is given to the displacement deciding circuits 8a, 8b and 9 before either one of displacement outputs of plural digits connected to an exclusive OR circuit 7 has the value different from the displacement outputs of other digits. Therefore the circuits 8a, 8b and 9 never detect the movement of the mouse 3 before the moved variable of the mouse 3 exceeds a fixed distance. Thus the undesired movement information on the mouse 3 is never transmitted to a computer game machine as the control information. Then the input control equivalent to that of a joy stick (input device) is attained with movement of the mouse 3 when the computer game machine is connected to the mouse 3.

Title: Composite roll for rolling metal and its production
Inventor: KIKUHARA TAKASHI
IPC: C22C38/22
Filed: 1990-06-25
Abstract: PURPOSE:To allow a composite roll to combine high thermal shock cracking resistance with high wear resistance by constituting the composite roll of a core material made of low alloy steel having a specific hardness lower than that of outer layer material and an outer layer material made of high alloy steel in which hardness, structure, and residual stress are specified, respectively. CONSTITUTION:This composite roll is constituted of a core material made of low alloy steel having a hardness of >=35 Shore hardness and lower than the hardness of outer layer material and an outer layer material made of high alloy steel having a martensitic structure of >=80 Shore hardness and <=15vol.% retained austenite content and also having a compressive stress of >=70kg/mm<2> residual stress at the outermost surface. In order to produce this roll, progressive hardening in which, while applying progressive heating to the outer layer material alone up to a temp. not lower than the austenite transformation point, a liquid refrigerant is sprayed on the heated part is performed. Then, high-temp. tempering treatment in which the amount of retained austenite phase in the outer layer material is regulated to <=15vol.% is carried out. Since tempering at a temp. as high as >=300 deg.C is made possible even if the surface hardness is regulated to a value equal to that of the conventional roll, resistance to thermal shock can be improved while maintaining wear resistance equal to that of the conventional roll.

Then the power potential is set at >= a level that is lower than the potential level of the VDD by a degree equal to the difference of threshold voltage between both TR MP1 and MP2 during or after the rise of the power voltage.

IPC: H03M1/14
Filed: 1985-07-26
Abstract: PURPOSE:To unify a power voltage and a reference voltage of an AD converter by providing a circuit converting an input voltage to a level of the AD converter. CONSTITUTION:A level conversion input circuit connected to an input signal terminal Vin of four AD converters 1-4 is provided. When an input voltage A is 0-V1/4, a voltage at a terminal M is changed linearly from a reference voltage terminal lower limit Ref(-) to a reference voltage terminal upper limit Ref(+). When the voltage A reaches the value V1/4, a diode D1 is turned on and when the voltage A is V1/4-V1/2, the voltage at the terminal N changes from Ref(-)-Ref(+). With the input voltage A at 0-V1 in this way, the voltage at terminal M- terminal N- terminal P- terminal Q changes linearly as Ref(-)-Ref(+) sequentially. Thus, the power voltage of the converters 1-4 and the reference voltage are unified.

Title: Instantaneous service interruption processor for equipment using computer
Inventor: TAKEHARA KIYOTAKA
IPC: H02J9/00
Filed: 1989-06-27
Abstract: PURPOSE:To omit a back-up power supply required for a processor by restoring the working state which is written into a memory before a service interruption when the output voltage of a time constant circuit is kept at a level higher than the prescribed one in a reset mode and initializing the time constant circuit in other modes. CONSTITUTION:A time constant circuit 4 starts the discharging with occurrence of a charged service interruption signal in a normal state. Then a processor 1 is reset after the service interruption is restored. At the same time, the working state written into a memory 2 before the service interruption is restored when the output voltage of the circuit 4 is set at a level higher than the prescribed one. Otherwise the circuit 4 is initialized. Therefore the output voltage of the circuit 4 exceeds a prescribed level with an instantaneous service interruption. Meanwhile the output voltage of the circuit 4 drops and the circuit 4 is initialized with a service interruption of a long period of time. Thus it is possible to select the process of the processor 1 after restoration of the service interruption just with use of a back-up power supply for the memory 2 without using any back-up power supply to the processor 1.
