Patent JP-H07266244-A (JP)
Title: Power screw fastener
Inventor: TANAKA TERUO
IPC: B25B21/00
Filed: 1994-03-25
Abstract: PURPOSE:To enable operations including secure tightening to be performed easily in a small place by providing a one-way clutch comprising a roller used in an inner ring and two outer rings assembled, attaching a handle to each of the two outer rings, and moving the handles back and forth in opposite directions. CONSTITUTION:A roller and a ball 2 are used in an inner ring 1 having a projection or a hole to which a socket or bit is attached, and two outer rings are assembled to form a one-way clutch. Handles 5, 6 are attached to the two outer ring. The two handles 5, 6 are moved back and forth in opposite directions to rotate the inner ring 1. Because power is utilized only for temporarily tightening a screw, its magnitude is reduced. After the screw is temporarily tightened, a secure tightening operation is started immediately. A screw tightening operation including secure tightening can thus be performed easily even in a small place.

Title: Method and device for controlling waveform
Inventor: UENO KAZUYOSHI
IPC: H04R3/04
Filed: 1989-04-28
Abstract: PURPOSE:To attain a test with use of the virtual characteristics undergone the qualification by applying the target signals inputted continuously to a system to be controlled after changing these signals by their control characteristics, correcting the control characteristics based on the answer signal and the target signal, and qualifying the control characteristics based on the qualifying coefficient. CONSTITUTION:A drive signal arithmetic means 6 changes the target digital signal based on the control characteristic received from a storage means 12. A D/A conversion means 8 applies the digital signal to a system 10 to be controlled as an analog signal. A correction coefficient arithmetic means 20 compares the target signal stored in a target signal storage means 4 with the corresponding answer signal received from the system 10 and operates a correction coefficient based on the difference between both signals. Then a control characteristic correction/qualification means 19 corrects and qualifies the control characteristic stored in the means 12 based on the computed correction coefficient and the qualification coefficient stored in a qualification coefficient storage means 17. Thus such a virtual environment that is expressed by the qualification coefficient can be simulated even if only the basic characteristic of the system 10 is known.

Title: Fuel supply device for internal combustion engine
Inventor: TORII MIKIO
IPC: F02M55/02
Filed: 1996-05-01
Abstract: PROBLEM TO BE SOLVED: To provide a fuel supply device for an internal combustion engine, in which the pressure pulsating amplitude decreases in the longitudinal direction of a delivery pipe. SOLUTION: A partitioning plate 12, which separates a lower chamber 13 from an upper chamber 14, is placed in side a delivery pipe main body 11 having a plurality of injectors 23, 24, 25, 26. A communicating space 15 is formed on one end side of the partitioning plate 12, while an entrance space 21 as another communicating space is formed on the other end side. Since the supply of the fuel to the lower chamber 13 is conducted on both sides, or the communicating space (15) side and entrance space (21) side, the variation of the pulsating amplitude is small.  Accordingly, since the fuel pressure can be uniformed relatively among individual injectors and on the injector entrance sides the amplitude of fuel pressure pulsation at the injector entrance, which occurs immediately after the injection among a plurality of injectors, can be restricted, thereby reducing the degree of ununiformity of fuel injection characteristics.

Patent JP-S62266427-A (JP)
Title: Optical temperature sensor
Inventor: KURATA NOBORU
IPC: G02B26/02
Filed: 1986-05-15
Abstract: PURPOSE:To enable an arbitrary temperature to be detected by locating two optical fibers in the same groove, making the optical axes of the optical fibers agree with each other and selecting arbitrary one from a plurality of shape memory alloys. CONSTITUTION:An optical fiber 8b is fixed to a V-groove 9 and another optical fiber 8a is opposed to the optical fiber 8b at a space of the degree of 30mum while being pressed against the groove 9 by a leaf spring 14. Further, two shape memory alloys 12a and 12b are held by a rotary mount 15. When the temperature of, for example, the alloy 12a rises to exceed a prescribed temperature, the alloy 12a generates a force to restore an original shape and pushes a control rod 13a and a movable member 10 upward, compressing a coiled spring 11. Since, when the member 10 is pushed up, its end is projected into the groove 9 to push up the optical fiber 8a, its optical axis is deviated from that of the optical fiber 8b and the transmission of light between the optical fibers 8a and 8b is intercepted. Accordingly, a temperature rise above the prescribed temperature can be detected by the presence or absence of an optical signal.

IPC: H01L31/10
Filed: 1990-04-26
Abstract: PURPOSE:To enable correspondence by the same wafer to the different size of light-receiving regions at every object of usage, to standardize a manufacturing process, to improve yield and to shorten the term of work by separating a P<+> diffusion region and separating a P<+>-InGaAs photoabsorption layer 5 and a P<+>-InP window layer in consideration of the combination of the P<+> diffusion region in a chip separation process. CONSTITUTION:P<+>-InGaAs photoabsorption layers 5 and P<+>-InP window layers 6 are isolated respectively and formed selectively. P electrodes 8 are brought into contact with the P<+>-InP window layers 6 and connected to the P<+>-InP window layers 6 on SiN 7 with opening sections 11. An N electrode is formed on the N-InP substrate 1 side. When reverse bias is applied among the P electrodes 8 and the N electrode 9 in a semiconductor device shaped in this manner, light projected from the opening sections 11 is absorbed by an InGaAs photoabsorption layer 3, and carriers are generated. The carriers are isolated and drifted in a depletion layer extended by reverse bias, and changed into photocurrents.
