Filed: 1989-11-20
Abstract: PURPOSE:To obtain a light-receiving device of APD having a broad band low noise by providing a second kind superlattice vertically to a board for being made longitudinal APD(avalanche photodiode). CONSTITUTION:After an n-InP buffer layer 2 is made to grow on an n-type InP board 1 by molecular-beam epitaxy method, a longitudinal type second kind superlattice multiplication layer 3 is formed.

Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of additional parts for working out the original position by correcting the original position of an welding gun actuator based on the abrasion volume of both electrodes. The abrasion volume of one electrode is calculated by a driving position of a welding robot, and the abrasion volume of the other electrode is calculated by a driving position of the welding gun actuator.

A pair of electrodes 41 , 4u are touched and abutted to each other by driving a welding gun actuator 5. The total sum δ1 of the abrasion volume of a pair of the electrodes 41 , 4u is obtained from the difference between the present electrode contact position and the electrode contact position before abrasion of the welding gun actuator 5, and the abrasion volume δu of the other electrode 4u is obtained by subtracting δ1 horn δ1 . The original position of the welding gun actuator 5 is corrected based on the original position X0 δ1 , and δu after the electrode abrasion.

Filed: 1989-11-17
Abstract: PURPOSE:To enable sure and quick detection of warp by hooking an end of a warp in beating with a claw positioned at the side of the woven cloth relative to the cloth fell using a weft pushing member attached to a reed, bending the tip end of the detection needle and detecting the flexure of the needle. CONSTITUTION:An inserted weft S is beaten to a cloth fell L by pushing with a reed dent 7. In the above process, an end of the weft S at the side opposite to the nozzle is hooked with a claw 23 placed at a position retreated from the cloth fell L to the side of the woven fabric C. The hooking is carried out by the aid of a weft-pushing member 10 having a slit 11 and placed on a reed 2 interposing a gap (d) from the reed in the direction of the cloth fell L of the reed dent 7. At the same time, the tip end part 32 of a flexible detection needle 30 is bent toward the beating direction by the apparent rigidity of the weft S. The presence of the flexure of the needle is detected by a strain gauge 33 to detect whether the weft S is normally inserted or not.

Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To prevent the burning of the connected wires in a terminal box by setting the upper end of a heat section lower than the upper face of a large- diameter bolt by a specific length when a bolt heater is inserted into a hole at the center section of the large-diameter bolt, forming the portion above it into a nonheat section, and providing the heater terminal box at the position apart by a specific length above the fastening nut of the large-diameter bolt. SOLUTION: When a bolt heater 1 is inserted into a bolt heater hole 5 at the center section of a large-diameter bolt 13 having the diameter 50mm or above, the upper end of a heat section 3 is set lower than the upper face of the large-diameter bolt 13 by 10-30mm, the portion above it is formed into a nonheat section 4, and a heater terminal box 7 is provided at the position apart by 100mm or more above the fastening nut 8 of the large-diameter bolt 13. Most of the heat generated by the heater 1 is transferred only to the bolt 13, and the heat transfer to the terminal box 7 is sharply reduced. The heat transfer to the terminal box 7 from the nut 8 becomes zero, and the heat transfer to the terminal box 7 is sharply reduced due to the heat radiation from the non-heat section 4. The burning of the terminal box 7 by the bolt heater 1 is prevented.

Title: Electromagnetic power supply apparatus
Inventor: ITO MAKOTO
IPC: H01F38/14
Filed: 1992-11-11
Abstract: PURPOSE:To provide an electromagnetic power supply apparatus, which can prevent the breakdown of ferrite at a butting edge and can realize the decrease in gap loss of laminated magnetic sheets. CONSTITUTION:A primary core 1 and a secondary core 3 are butted, and a magnetic circuit having a gap (closed magnetic path having a gap) is formed. A high-permeability thin magnetic part 6 is deposited on at least one butting edge 15 or 35 of both cores 1 and 3. The butting edges 15 and 35 of both cores 1 and 3 hold the high-permeability thin magnetic part 6. When the raw material of the cores 1 and 3 is made to be ferrite, the shock at the time of the core butting is absorbed or dispersed in the magnetic part 6 because the magnetic part 6 protects the butting edges 15 and 35 of the cores 1 and 3. Thus, the cracking and the chipping of the butting edge of the ferrite core can be prevented.
