Patent JP-H01241881-A (JP)
Title: Pulse oscillation laser power source
Inventor: OKADA TOSHIHARU
IPC: H01S3/0971
Filed: 1988-03-24
Abstract: PURPOSE:To improve the efficiency of a laser output with respect to the input of a power source when a Q switch is employed as a pulse oscillation laser and to improve its maximum charging/discharging repetition speed by breaking a discharge current from a charge/discharge circuit for radiating light from a lamp on the way of the discharge, and using the current as the charging current of the circuit. CONSTITUTION:When an oscillation is abruptly raised from a state that a laser oscillation is stopped in a Q switch pulse laser oscillator and a current breaking thyristor 5 is opened immediately after a giant pulse is generated, a discharge current flowing to a flash lamp 9 passes through the thyristor 5 to temporarily reversely charge a capacitor 2 and then passes through a regenerative diode 6 to recharge the capacitor 2. Accordingly, the discharge current which does not contribute to the laser oscillation is recharged in the capacitor to recover the energy thereby to improve the efficiency of the power source by 25% at the maximum, and to increase its maximum charging/discharging repetition speed.

CONSTITUTION:A work W is held with a punch 3 fitted to a lower holder 1 of a press and a pad 5 fitted to an upper holder, and the work W is held between the 1st sectional die 13 and a pad 31 by advancing to the left the 1st sliding cam 7 by descending the 1st driving cam 15 and on the other hand by advancing to the right the 2nd sliding cam 23 by descending the 2nd driving cam 33. The above movement is further progressed and the pad 31 is retreated against a spring 29 and the work W is trimmed at a cutting edge part 14. Both sliding cams are successively advanced and scraps S generated by the above trimming are worked by bending between a pressing part 18 of the 1st sectional die 13 and the 2nd sectional die 16, and after it is deformed to a small-sized and less contacting faces shape it is fallen to a scrap chute 37 for discharge.

Title: Sample-hold circuit
Inventor: NAKAMURA KATSUSHI
IPC: G11C27/02
Filed: 1994-04-08
Abstract: PURPOSE:To avoid the restriction of the speeding-up of the whole of a circuit by, for example, connecting outputs of first stages of a two stage type operational amplifier with prescribed voltages via analog switches and initializing output voltages held on Miller phase compensation capacitances at the time of resetting a sample-hold circuit. CONSTITUTION:Input analog signals from terminals 3, 4 arc sampled on capacitances C1, C2 with a clock theta1 via analog switches S4, S5 and terminals 7 to 12 are connected to a grounding terminal 2 by S6 to S11 and then the sample-hold circuit is reset. At the time of a holding, S6 to S11 are turned OFF with theta2 and the reset is released and S1 to S3 are turned ON. Then, input signals held on C1, C2 are shifted to C3, C4 and voltages of signals are amplified by the ratio of respective capacitances to be outputted to terminals 9, 10. Further, since an initializing circuit 15 is connected through terminals 13, 14 and via S12 with theta1, a resetting time is shortened without increasing the stationary current of the operational amplifier.

Title: Laminated capacitor
Inventor: KABASAWA HIDEKI
IPC: H01G4/30
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a laminated capacitor which is free from inside structural defect. SOLUTION: Each circumferential edge part of each inside electrode 23 is formed uneven and a laminated capacitor is formed by laminating the inside electrode 23 and a dielectric layer 21a. Therefore, a circumferential part of the inside electrode 23 and the dielectric layer 21 are engaged with each other and inside strain due to expansion and contraction of the inside electrode 23 and the dielectric layer 21a can be avoided. Therefore, it is possible to greatly reduce generation rate of structural defect (such as delamination and cracks) caused by oxidation expansion of the inside electrode 23 consisting of Pd, etc., and the dielectric layer 21a and to obtain a highly reliable laminated capacitor.

Title: Method for setting service life of endless belt for twin belt type continuous casting machine
Inventor: KATAHIRA KEIICHI
IPC: B22D11/06
Filed: 1995-03-29
Abstract: PURPOSE: To prevent the development of casting flash on a cast strip by measuring the height of edge wave at the edge parts in the width direction of a belt and whether the crack exists or not at the position of an endless belt abutted on a pulley and deciding the service life of the belt. CONSTITUTION: The endless belt 1 is abutted on the pulley 3-2. The variation of eddy current developed in the endless belt 1 is detected by the electromagnetic induction of a proximity sensor 11 and the height (t) of the edge wave and whether the crack exists or not is measured. When the height (t) of the edge wave reaches the preset upper limit value, or when the crack develops on the endless belt 1, it is decided that the service life of the endless belt 1 comes to the limit. The preset upper limit value of the height (t) of the earing wave is defined to be 0.1-0.3mm. In the case of largely exceeding the upper limit value of the height (t) of the edge wave during operation, or in the case of detecting the crack, the operation is stopped. By this method, the accident, such as flow-out of molten metal, cut-off of the endless belt 1, can be prevented.
