Title: Optical detector
Inventor: INUYAMA SHIGEYOSHI
IPC: G01B11/00
Filed: 1993-08-06
Abstract: PURPOSE:To provide an optical detector improved in terms of reliability for making judgement about transition from shade detection state to shade non- detection state by sending non-shade information, when the non-shaded state of an object detected after shading therewith continues for the predetermined time. CONSTITUTION:This device is equipped with detecting means 13 and 14 for detecting the existence of the shaded state of an object at every constant time, a means KC for continuously counting the occurrences of shade non-detection state after transition from the detection of shading with an object to shade non-detection state, and means 13, 14 and ZS for outputting non-shade information, when the predetermined occurrences of the shade non-detection state are counted. Erroneous touch-off information is thus prevented from being uselessly outputted by sending the non-shade information when the predetermined occurrences of the shade non-detection state are counted.

Abstract: PURPOSE:To obtain the titled highly reliable parts without any voids in an Au-Si eutectic crystal formed at a pallet-bonding by applying annealing treatment after plating in electronic parts plated with gold with an Ni-Co plating as the substrate. CONSTITUTION:A pad of a high m.p. metal material is formed, for example, on the surface of a ceramic substrate 1 on the surface of a metal, Ni is plated on the pads 2a-2c formed by sintering along with the substrate 1 and a plated film 3 is formed. Then a lead 5 is brazed on the pad 2c, for example, with a eutectic silver solder. Then an Ni-plated film 6 is formed in specified thickness by electroplating, then a Co plated film 7 is formed in specified thickness and further an Au plated film 8 is coated in specified thickness. Subsequently, the electronic parts are heated at about 450 deg.C for about 10min in an N2 atmosphere and then annealed. The residual gas in the plating is removed by the treatment and the objective is achieved.

Title: Electrophotographic sensitive body for positive charging
Inventor: TAMAKI KIYOSHI
IPC: G03G5/05
Filed: 1986-08-20
Abstract: PURPOSE:To improve the scratch resistance and durability and to provide superior resistance to oxidation by ozone by incorporating an electric charge transferring substance into the electric charge generating layer and a specified compd. into the generating layer or the protective layer. CONSTITUTION:An electric charge transferring layer 2 and an electric charge generating layer 3 are laminated on an electrically conductive support 1 and a protective layer 7 is formed on the layer 3 as required. The electric charge generating layer 3 contains an electric charge transferring substance 5b and the layer 3 or the protective layer 7 contains a compd. represented by formula I (where each of R1 and R3 is 1-18C alkyl and each of R2 and R4 is 1-18C alkyl or alkoxy). Since the compd. represented by the formula I prevents the deterioration of the substance 5b by ozone by self-oxidation, the compd. is preferably incorporated into the protective layer 7 formed on the layer 3 as required but it may be incorporated into the layer 3 or may be further incorporated into the layer 2.

Title: Radio communication equipment
Inventor: OMAGARI NAOYUKI
IPC: H04B1/40
Filed: 1989-07-27
Abstract: PURPOSE:To easily prevent the production of a beat frequency by varying a clock frequency of a microcomputer in the case of a communication channel in which a beat frequency might take place. CONSTITUTION:When beat disturbance takes place in a reception frequency of, e.g. 8th channel, it is stored in a storage means 8a. When the 8th channel is read from the channel storage means during scanning, a high level signal is outputted from a control means 8 composed of a microcomputer, a transistor(TR) 9a of a frequency control circuit 9 is turned on and a capacitor 9b is connected in parallel with a capacitor 10b of a clock circuit 10. Since the capacitance of the capacitor is increased, the clock frequency to the control means 8 is lowered. Thus, the production of the beat frequency is easily prevented.

Title: Wafer vacuum chuck pad
Inventor: ISHIKAWA TOSHIHIKO
IPC: B24B37/04
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To provide a wafer vacuum chuck pad capable of vacuum holding wafers of different sizes. SOLUTION: A wafer vacuum chuck pad 68 has a circular groove 78A at the center of a wafer vacuum chuck surface 76A and three concentric annular grooves 78B-78D around it. To the grooves 78A-78D air intake lines 80A-80D are connected, and valves 86A-86B are opened/closed to control the air intake. For vacuum chucking a wafer 26, air is sucked only those grooves located inside the outer diameter of the wafer 26. Thus each of wafers 26 of various sizes can be vacuum chucked over the entire surface by a single-wafer vacuum chuck pad.

Title: Stopping mechanism for runaway of head positioning device
Inventor: KAKIZAKI TAKAO
IPC: G11B21/02
Filed: 1985-09-06
Abstract: PURPOSE:To prevent the occurrence of head crush by sealing both end parts of a hollow structure by the first and second sealing members and preventing scattering to outside of dust generated from a sliding part at the time of stopping runaway. CONSTITUTION:A head arm 5 that holds a magnetic head is attached to a magnetic circuit housing 9 rotatably through an oscillating shaft 7. A magnet 11, a driving coil 13 and a coil bobbin 15 are housed in a housing 9. When the bobbin 15 moved in the direction of arrow mark beyond the extent of operation, the bobbin 15 collides against the sealing member 31 of a runaway stopping mechanism 1. The convex part of the member 31 is deformed flat and a buffering member 27 enters a hollow member 17 bending a coil spring 21, and thereby, kinetic energy of the movable part is absorbed. At this time, air in a space 35 flows from a gap 29 to a space 41 through a through hole 23d, and a sealing member 39 becomes projection outward to complete the state of stopping runaway. Thus, the scattering to outside of dust generated at the time of stopping runaway can be prevented.
