Title: Noise lowering circuit
Inventor: TOKUSHIGE KAZUO
IPC: H01L27/06
Filed: 1987-05-27
Abstract: PURPOSE:To offset noise due to a load input, by juxtaposing a first circuit, which uses an input signal to drive a load having input capacity to a substrate and a wiring, and a second circuit with a load, which has almost the same capacity as the first circuit and is driven by a signal reverse in its polarity to that in the first circuit. CONSTITUTION:This circuit is provided with the following parts: a first driving circuit 1 formed of an inverter circuit, a second driving circuit 2 formed of an inverter circuit, a polarity inversion driving circuit 3 with an input signal phi, and a capacitor 5 disposed on an output side of the driving circuit 2 so as to have a capacitance C2 equal to an input capacitance C1 to a substrate in a circuit to be driven 4. These are formed on a similar substrate. When this composition allows the input signal phi to operate the driving circuits 1 and 3 in reverse phases to each other and to charge the capacitor C1, the capacitor C2 is discharged. When the capacitors C1 and C2 are viewed at the same time, the charge and discharge are repeated with the same amount of charge to the substrate and hence noise generated on the substrate can be offset.

Title: Electric discharge processing device
Inventor: ASAKAWA HIROFUMI
IPC: B23H9/04
Filed: 1978-10-27
Abstract: PURPOSE:To make it easy to take out or insert the work from or into the opening of a processing tank, in an electric discharge processing device to give an aventurine finish to the surface of a particularly long work, such as a roll, and at the same time to reduce the amount of processing liquid. CONSTITUTION:Roll 1 to be processed is held horizontally and rotated in processing tank 5. Electrode 7 is placed so as to face roll 1 to be processed at the opening of processing tank 5.

By this, it is possible to reduce the amount of processing liquid compared with conventional devices. Since no electrode is placed on tank 6, it is easy to insert or take out roll 1 into or from the tank.

Title: Vehicle license number detection device
Inventor: TERAJIMA KOJI
IPC: G08G1/017
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To automatically correct the displacement of a vehicle despite the change or the vehicle passing position and to satisfactorily read the vehicle license number by detecting the displacement value of the vehicle when a vehicle is horizontally displaced from its prescribed position, using the displacement value as the correction value to change the detected distance threshold and then performing the feedback control to place again the vehicle at its prescribed position. SOLUTION: If a vehicle 5 passes through a position (hb), the shutter of a CCD camera 2 is released when the vehicle 5 is included in a distance covering the camera 2 through a position Lb (with the detection distance threshold set at the small value). Thus, the picture able center 21 of the camera 2 is controlled to secure coincidence with the center of the vehicle 5. If the vehicle 5 passes through a position (hc), the control is performed so as to increase the detection distance threshold to release the shutter when the vehicle 5 is included in a distance set between the camera 2 and a position Lc and to photograph a proper video image. Thus, it's possible to automatically control the detection distance threshold via the passing of several first vehicles if the passing position of the vehicle 5 is changed due to the road situation, etc.
