Patent JP-H08334800-A (JP)
Title: Optical signal amplifier
Inventor: TAKADA ATSUSHI
IPC: H01S3/07
Filed: 1995-06-08
Abstract: PURPOSE: To simply and compactly constitute an optical signal amplifier low in noise and to conduct phase synchronization of an exciting light beam and an input signal light beam by using an optical interferometer as the laser resonator of the optical signal amplifier. CONSTITUTION: This amplifier consists of a laser oscillator medium section 1 and a Sagnac interferometer 20. If laser oscillation takes place in the interferometer, interference between the oscillation light beam and the signal light beam occurs in an input output optical branching section 10 and an unbalance in the strength of clockwise and counterlockwise rotating light beams is generated. Third order optical nonlinear type medium (light power-medium) 30 and 31 inserted in the interferometer 20 vary their refractive indexes proportional to the incident light strength (light power-effect). Thus, the phase rotations of the clockwise and counterclockwise light beams are made different despite of the fact that the beams travel in a same optical path.  As a result, the two rotating beams again interfere with each other at the input output optical branch and a signal light component, which is made incident to the interferometer 20 that is the output coupler of the left hand laser oscillator, is generated in accordance with the phase difference.

Title: Caulking inspecting method and inspecting tool for connected pipe
Inventor: OZAWA YASUHIRO
IPC: G01N3/08
Filed: 1991-05-17
Abstract: PURPOSE:To quickly confirm the quality of caulking and confirm the completion of an inspection by driving a punch on the outer periphery near the insertion end section where the second pipe is normally inserted into the first pipe to form a double-portion with the pressure generating recesses on the single portion of the first pipe and rarely generating recesses on the double-portion. CONSTITUTION:When the depth of insertion of the second pipe 7 into the expanded port of the socket 4 of the first pipe 1 is insufficient, caulking recesses 8 are generated on outer peripheries of the first pipe 1 and the second pipe 7 at the single portion 1a of only the first pipe 1 and the non-insertion portion port of the second pipe 7 at the same interval. Caulking is inspected by driving a punch on the outer periphery of the end section (c) of the normal double- portion where the first pipe 1 and the second pipe 7 are overlapped at the time of caulking or separately. When the insertion depth is insufficient, the punch is driven to only the first pipe 1 at the portion (c), i.e., the abnormal single portion of the first pipe 1, a punch hole 12a remarkably recessed against the strength of the first pipe 1 is generated, and the fact that the caulking is defective and an inspection is completed is displayed.

Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To enable the high-speed processor, which operates while increasing the operating clock of the mother board side to a noninteger multiple, e.g. 1.5, to operate at a processing speed higher than a computer by making the maximum use of the latest computer architecture and characteristics of a processor operating with a high-speed clock although the processor was hardly synchronized with the timing of the mother board side because of higher operation, a pipeline processing, etc. SOLUTION: Whether or not the cycle is a memory read cycle is detected and when the relation between the clock of the system side and the clock of the high-speed processor side is specific in the memory read cycle, a burst ready signal is quickened in phase and outputted to a processor. Consequently, even when a period wherein data are effective on a data bus is earlier than a write cycle, the data can be sent and received without causing any error.

Title: Higher harmonic suppression device
Inventor: KOBAYASHI TADAO
IPC: H02J3/01
Filed: 1993-06-15
Abstract: PURPOSE:To prevent a higher harmonic due to device abnormality from being increased by surely detecting the device abnormality. CONSTITUTION:In a higher harmonic suppression device equipped with a filter F1 for carrier elimination provided with an inverter 1 and a capacitor C1 and a control circuit 2 for the inverter, the current of the filter capacitor C1 is detected by a current detector CT2. A higher-order higher harmonic current Ih-carr by a PVM carrier frequency flows on the filter capacitor C1. In an ordinary operation, the higher harmonic output current Ih-out of the device coincides with a detection higher harmonic current Ih-det, and the current Ih-carr can be kept constant, however, when the device abnormality occurs, it goes to the current Ih-outnot equal to Ih-det, and the current Ih-carr is increased. An absolute value detection circuit 26 detects the absolute value of the current Ih-carr from the output of the detector CT2, and a comparator 27 compares the absolute value with a reference value E0, and detects the device abnormality, then, stops the inverter 1 via a gate driving circuit 23.

Title: Reversibly temperature-indicating material
Inventor: INOUE YOSHIHISA
IPC: C09K9/00
Filed: 1988-06-10
Abstract: PURPOSE:To obtain a reversibly temperature-indicating material which has high heat resistance and quickly changes the color tone at a specified temperature by using a specified polycrystalline compound oxide containing Pb, Mg, Co and W as constitutent. CONSTITUTION:The title material contains a polycrystalline compound oxide represented by formula Pb(Mg0.5-xCoxW0.5)O3 (wherein 0<x<0.1). Known terperature-indicating materials include metallic iodides, liquid crystals, and electron accepting organic compounds, all of which have the problem of low heat resistance. The use of a metallic oxide, such as PbCrO4 or Tl2CrO4, in place of these materials has been proposed but these oxides change the color tone continuously with temperature rise although they have good heat resistance. The temperature-indicating material of this invention has high heat resistance and quickly changes the color tone at a relatively low temperature (about 35-45 deg.C); therefore, it can be used for various products.
