Title: Hydraulic circuit for closed circuit hydraulic transmission
Inventor: UEHARA KAZUO
IPC: B62D11/04
Filed: 1990-03-30
Abstract: PURPOSE:To compensate for linear running properties in a high load state by providing an equalizing valve to connect and disconnect high pressure circuits on both sides to and from each other and bringing the equalizing valve into a shut-off position by means of a differential pressure between the high pressure oil pressures of the high pressure circuits on both sides. CONSTITUTION:High pressure oil of a left high pressure circuit 22 is exerted on an end surface 78b of a lever body 78 and high pressure oil of a right high pressure circuit 27 is exerted on other end surface 72b of a spool 72. Since the pressure receiving areas of the end surfaces are identical to each other, when high pressure oil of the left high pressure circuit 22 is equal to that of the right high pressure circuit 27, the spool 72 is held in a communicating position regardless of the absolute value thereof. Since the high pressure sides of left first and second main circuits 3 and 4 are communicated with the high pressure sides of right first and second main circuits 7 and 8, respectively, through a throttle part 75, the pressures of the main circuits on the high side on both sides are held at the same value as each other to compensate for linear running properties.

Title: Abnormal state judging method of machine operating noise
Inventor: TAKANO IKUO
IPC: G01M99/00
Filed: 1995-04-06
Abstract: PURPOSE: To perform human sensor evaluation and correlativeness to be securable in judging a highly accurate abnormal state by comparing the threshold set at each specified plural strength level set according to a frequency zone with the generating frequency. CONSTITUTION: A detection signal out of an acceleration sensor 1 is inputted into a controller 10 making a central processing unit 100 a main body after removing any useless high frequency component in an input box 2, whereby a fast Fourier transform operational process and a trouble judging process based on operating noise and vibration are carried out at this controller 10. The judged result takes place via a display unit 8 connected to an interface 101 of the central processing unit 100. The detection signal of the sensor 1 inputted into the controller 10 via the input box 2 is converted at an analog-to-digital converter 5, and it is thus subjected to sampling according to a command of the CPU 100.  The detection signal subjected to the sampling is temporarily stored in a memory 7, and then the FFT operational process is carried out in a digital signal processor 6 by the command of the CPU 100, and thus the central processing unit 100 judges an abnormal state according to the operated result.

Title: Semiconductor ic
Inventor: IWAHASHI HIROSHI
IPC: H01L27/10
Filed: 1984-04-23
Abstract: PURPOSE:To make it easier to use a memory by making the power source supplied to a chip single by a method wherein a pressuring circuit in the chip enables data write-erase at the supplied pressurizing potential. CONSTITUTION:In the case of data readout, a high-voltage impressing terminal H and a clock pulse input terminal CL are at ''0'' level, and a write-readout control signal input terminal R is at ''1'' level, therefore, the output of an output terminal Out becomes ''0'' and ''1'', resulting in the action as a normal inverter. Next, in the case of data write-erase, the terminal R is at ''0'' level, and a high voltage supplied by a charge pump circuit is impressed on the terminal H, then, clock pulses are impressed on a terminal CL. When an input terminal I is at ''1'' level, the output terminal Out turns to ''0'', however, when the input terminal I is at ''0'' level, transistors 32 and 35 turn OFF. Although a transistor 37 has a gate signal R of ''0'', it is ON because of being a depletion transistor, and the voltage of the terminal Out does not become ON.

Title: Reset circuit
Inventor: AIDA YASUSHI
IPC: H03K17/22
Filed: 1989-04-03
Abstract: PURPOSE:To produce a sure reset signal free from the mixture of an error signal by outputting the output signal of a one-shot trigger circuit which outputs a signal when a prescribed time lapses after the input of a holding signal as a reset signal. CONSTITUTION:When a power supply Vcc is applied and the voltage of the Vcc exceeds the reference voltage Vref, a power voltage detecting circuit 1 works and the detecting signal has gradually higher levels. Then the detecting signal of a high level is supplied to a one-shot trigger circuit 2. At the same time, a holding signal S4 of a high level that has the prescribed time width is supplied to the circuit 2. Meanwhile a reset signal S3 holds a low level. Thus it is possible to avoid such a failure where a microprocessor, etc., starts its working in an incomplete state to cause a runaway or sometimes to destroy the memory contents with the supply of the signal S3.

IPC: B41M7/00
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To obtain the subject composition having excellent water repellency and light resistance by adding fluorine resin particles and an ultraviolet absorber to an overprint varnish. SOLUTION: This composition is obtained by adding (A) fluorine resin particles and (B) an ultraviolet absorber to an overprint varnish. Preferably 20-120 wt.% of the component A is mixed with 1-20 wt.% of the component B based on the solid content of the objective composition.

Title: Screw for terminal and terminal block device
Inventor: KAMINUMA HIROSHI
IPC: H01R9/22
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To prevent a screw from escaping from a through hole of a washer without increasing caulking of the washer, or without caulking all over its circumference. SOLUTION: A terminal screw is fitted onto a square washer 17 by caulking the sections of the square washer 17 which are indicated by marks 17b to 17e after insertion in the through hole 17a of the square washer 17. If the diameter of the through hole 17a after caulking is taken as D2, and the relief diameter of a screw neck 12 is taken as d2, a relation of d2>D2 is satisfied. If the diameter of the through hole 17a before caulking is taken as D1, it is natural that the relation of D1>d2 is satisfied. However, it is preferable that the value of D1-d2 is as small as possible.  Even if looseness is generated between the terminal screw and the through hole 17a of the square washer 17, the relation of d2>D2 is satisfied, therefore, the outer periphery part of an end ring 13 is brought into pressure contact with a protruding part 17f formed in the through hole 17a by caulking, and the outer periphery part of the screw neck 12 is brought into pressure contact with other sections of the through hole 17a. By bringing the two sections of the terminal screw into pressure contact with the through hole 17a, it is kept in such a condition as the terminal screw is locked against the through hole 17a, thus it is possible to prevent such failure as the screw for terminal leaves the square washer 17.
