Abstract: PURPOSE:To exactly adjust the rail width, by moving a movable rail in the direction of a set position, after the movable rail moves in the direction opposite to the set position so as to go across an origin. CONSTITUTION:An origin detection means 7, a driving means 1, a control means 20 and a counting means are installed. A CPU 20 controls each part, on the basis of a program stored in a built-in ROM. By the number of pulses of a pulse signal inputted from an encoder sensor 3, the rotation angle of a driving motor 1 for changing rail width is recognized, and the rotation of the driving motor 1 is driven and controlled, on the basis of the number of pulses. In this case, the CPU 20 reads a table showing error characteristics between the theoretical number of pulses corresponding with the moving amount of rail width which is previously stored in a storage part 21 and the practically necessary number of pulses. On the basis of the read error characteristics, the theoretical number of pulses is corrected, and the practical number of pulses is set.

Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To enhance heat rate by suppressing shock in switching a high/low pressure oil by a high/low pressure switching valve and increasing the high/low speed of a ram. SOLUTION: A two-pressure hydraulic circuit is provided with a high/low pressure switching valve 45 which is equipped with a P-port communicating with a high-pressure oil supply pipe line, a T-port communicating with a low- pressure oil supply pipe line, and a B-port communicating with a pipe line for supplying pressured oil to a hydraulic cylinder. The main spool 55 inside the high/low pressure switching valve 45 moves to switch a high pressure line HPL that is communication with the P-port and the B-port and a low pressure line LPL that is in communication with the T-port and the B-port. Immediately before switching from the low pressure line to the high, the high pressure oil from the P-port is made preliminarily flow to the B-port through a by-pass circuit 73 in the main spool 55, causing a gentle change in pressure, and thereby reducing shock at the time of switching of the high/low pressure; as a result, oil hammer is reduced.

IPC: E04H9/02
Filed: 1993-01-12
Abstract: PURPOSE:To forecast the seismic intensity at a forecasting point by calculating the characteristic values from the accelerating speed wave form or speed wave form during the course from the arrival of the P wave to the arrival of S wave at the observation point in the vicinity of an electric power source and calculating the damping quantity corresponding to the distance from the electric power source, from these characteristic values. CONSTITUTION:A seismic intensity forecasting system is constituted of an observation point device 1, central observation center device 2, and a forecasting point device 3. By the device 1, two horizontal compoments and vertical component of the seismic wave are observed, and after amplification, A/D conversion is carried out, and the characteristics such as the amplitude, phase, continuation time, ratio between the horizontal movement and vertical movement, etc., are calculated from the accelerating speed wave form or the speed wave form of the P wave which reaches at first by a mu-CPU, and the direction, depth of a seismic source, seismic intensity and seismic source distance at the observation point, seismic source distance, and the seismic source distance at the forecasting point are calculated from these characteristic values. These data is transmitted to the center device 2, and the seismic intensity at the target forecasting point is calculated by a host computer. The forecasted seismic intensity = C0 + seismic intensity of initial movement at observation point + C1X log (seismic source distance at observation point) - C2 X log (seismic source distance at forecasting point (in this equation, C0, C1, and C2 are constants).

Title: Probe for water-dip surface wave
Inventor: HASUO YASUNORI
IPC: H04R17/00
Filed: 1989-01-12
Abstract: PURPOSE:To detect a defect present in the surface layer part of a body to be inspected without reference to the holding direction of the probe and to shorten the inspection time by providing a vibrator and an acoustic lens in a case. CONSTITUTION:When a pulse signal is applied to the vibrator 5 in the case 4, the vibrator 5 oscillates an ultrasonic wave by piezoelectric vibration and the oscillated ultrasonic wave is emitted underwater through the acoustic lens 6 and converged on a focus F through the lens operation of a curved surface 6a. At this time, a water-dip surface wave 3 is excited around the focus F on the surface 1a of the body to be inspected and propagated having isotropy from the focus F to the surface 1a at an angle of incidence from the curved surface 6a. Consequently, the probe P is scanned on the surface 1a at constant pitch and then if there is the defect in the surface layer part of the body 4 to be inspected, a vertical surface wave is made incident once in the direction of the defect, so the defective echo of a reflected wave which is reflected vertically from the defect can be detected.

Title: Limiter
Inventor: YAMAGUCHI HIROYASU
IPC: H03G11/00
Filed: 1982-01-13
Abstract: PURPOSE:To obtain a limiter circuit of high performance with a simple constitution, by  supplying a bias power supply to the base of one of a differential pair of transistors  and at the same time connecting an output terminal and a level limiting transistor to  the base of the other transistor respectively. CONSTITUTION:An end of a resistance R11 is connected to an input terminal, and the  other end is connected to an output terminal, the base of a transistor TRQ1 and the  collector of a TRQ5 of opposite polarity. A TRQ2 having a bias power supply VB connected to the base forms a differential pair with the TRQ1. The emitters of the TRQ1 and Q2 are connected in common and then connected to a power supply VCC via a  constant current source I1. The base of the TRQ5 is connected to the collector of the  TRQ2, and the collectors of the TRQ1 and Q2 are connected to a negative power supply via a current mirror pair of TRQ3 and Q4. When the level of an output terminal  OUT rises up to the value approximately equal to the voltage VB, the TRQ1 becomes  nonconductive and the TRQ2 starts its conduction. When the current of the TRQ2  exceeds that of a TRQ4, this differential flows to the base of the TRQ5. Then the collector current of the TRQ5 flows, and the voltage drop of an R11 is increased and then  becomes steady when the base potential of the TRQ1 is equal to the voltage VB. Thus the output voltage is kept at a constant level.

Abstract: PURPOSE: To perform high-speed reproduction and high-speed search stably by forcing a reproducing element to shift in track by one pitch except at the recording part of the 3rd tracking control reference signal for tracking polarity swtiching.  
     CONSTITUTION: For trick play, a kick pulse genertor 25 generates a kick pulse on the basis of an external input 23 from ten keys, etc. Once the kick pulse is generated, a tracking coil 17 is fed with electricity through a driving circuit 16 to kick a reproducing stylus 4 in a prescribed direction.
