Title: Liquid crystal display driving device
Inventor: YOSHIDA MICHIO
IPC: G09G3/18
Filed: 1989-02-10
Abstract: PURPOSE:To easily reduce electric power consumption without deteriorating the characteristics of the liquid crystal display element by providing the power source of the driving circuit of the liquid crystal display element with plural pieces of bidirectional transfer gates and adding a function to stop the clock signal of the liquid crystal display element. CONSTITUTION:Both bidirectional transfer gate circuits 20, 21 conduct and a clock phiLCD for a liquid crystal operates when the standby signal generated in the internal circuit of an integrated circuit device or inputted from an external terminal is a VSS level. The liquid crystal display element makes an ordinary operation of non-lighting when segment data is the VSS level and of lighting at a VDD level. The liquid crystal driving clock phiLCD stops and both the bidirectional transfer gate circuits 20, 21 become non-conducting when the standby signal attains the VDD level and, therefore, the power source for driving the liquid crystal is not supplied and the output attains a high impedance state. The standby function is easily realized in this way without deteriorating the characteristics of the liquid crystal display element and the electric power consumption is reduced.

Title: Noise reducing device
Inventor: YASHITA YUKIKO
IPC: H04N11/04
Filed: 1992-01-20
Abstract: PURPOSE:To reduce a noise, and to suppress an oscillating phenomenon of a circuit system, which is generated in connection therewith. CONSTITUTION:A video signal becomes a digital signal by an A/D converter 2. By a subtracter 6, a frame difference signal to a signal of one frame before is obtained. In order to fetch a noise component from this frame difference signal, an Hadammard transformation, a non-linear processing and an Hadammard reverse transformation are executed. An output signal of the Hadammard transformation sometimes takes a value for oscillating a circuit system, therefore, the value for oscillating the circuit system is detected by a comparing/selecting circuit 21. In the case the oscillation value is detected, no oscillation is executed and a value having a noise reducing effect is outputted, and in other case, an output value of an Hadammard reverse transformation circuit is outputted. This output value is subtracted from an input signal by a subtracter 3 and an output signal whose noise is reduced is obtained.

Abstract: PURPOSE: To save fresh water used without spoiling by recirculating pressurized water into a lower water tank for reuse which is pumped up by the tank to each of a bearing, a sealing device, and an upper water tank and overflows from them.  
     CONSTITUTION: In operation of a water wheel, fresh water in a lower water tank 7 is forced into a pressure water tank room 8 through a suction pipe 10, a check valve 11, and a feed water pipe 13 by a pump 9 and then goes into a lower pressure room 5 through a communication hole 19, from which it runs through a friction part of a main bearing 1 into an upper pressure room 4. Fresh water in the upper pressure room 4 is discharged into the lower water tank 7. As the pump 9 suctions excessively much water, fresh water overflows from the bearing into the upper water tank through a communication pipe 12, in which it gains in amount up to a specified water level. The overflowing water is turned back into the lower water tank through the communication pipe 14. However water leaking from a packing is required to add, fresh water can be saved without spoiling.
