Abstract: PROBLEM TO BE SOLVED: To prevent the damage of the valve seal of a hydraulic piston valve. SOLUTION: A seal holder 36 is fitted to be advanced/retreated in the inside of a hydraulic piston 126, and a valve seal-138 is retained in a through hole 36a formed in this seal holder 36. A partitioning wall is formed in the inside of the hydraulic piston 126, and a through hole 126d is arranged in the center of the partitioning wall. A seat surface 126e to which the end seal part 138a of the valve seal 138 is allowed to abut is arranged around the circumference of this passage hole 126d. The seal part of the valve seal 138 is fiat, and retreated in the inside of the passing hole 36a formed in the seal holder 36. Also, the seat surface 126e is annularly projected to the side of the valve seal138.

IPC: H05K13/08
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To provide a component mounting device wherein a part is accurately mounted, even if the part is replaced due to the component being run-out. SOLUTION: A supply component vacuum-clamped with a vacuum-clamping nozzle is recognized at a specified recognition position by a component recognizing device, and based on the recognition result, a vacuum-clamping position is corrected and a vacuum-clamped component mounted on a substrate.

Filed: 1985-12-26
Abstract: PURPOSE:To prevent reflection from an end surface of beams in an LED, and to obtain spontaneous emitted beams by roughening one of the end surfaces of the end-surface light-emitting type LED. CONSTITUTION:In an end-surface light-emitting type LED 11, in which a V groove is buried onto an n-InP substrate 15 and which has InP/InPGaAs hetero- structure, a nonreflective coating is applied on a light-emitting end surface 21 in the same manner as conventional examples, and an end surface 13 on the side reverse to the end surface 12 is roughened, or an inclined plane 14 including an active layer 17 is roughened. Consequently irregular reflection is formed and the reflectivity lowers, and since the end surface 12 consists of a nonreflective film, the intensity distribution of light from the LED becomes of a Gauss curve shape, and intensest beams enter an optical fiber 26. HF: HNO3=1:1 is used for InGaAs 22 and HCl is employed for InP 15 as an etching liquid for surface roughening, thus bringing a complete nonreflective state.

Filed: 1985-12-27
Abstract: PURPOSE:To eliminate an origin detection means on a scan means and to efficiently use a small space by installing an origin detection means detecting the origin of an irradiating means irradiating spot light on an original on a main body side. CONSTITUTION:The detector 138 which detects the origin (initial position) of a spot light source 131 and is composed of a microswitch is installed on the side of the main body. When a power source switch is turned on, a main processor group stops an optical system, that is, a carriage 411 at its initial position (origin), and rotates a motor 135 to shift a timing belt 134. Together with the shift, the spot light source 131 moves, and its arm 139 turns on the detector 138. The spot light source 131 is judged to lie at its initial position (origin), and the motor 135 stops. Thus an original detection means can be eliminated out of the carriage, whereby the moving range of the spot light source can be expanded up to length corresponding to the width of an original platen.

IPC: G01S13/931
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a protection sensor for detecting a moving object using a Doppler type radar, for the movement of the object relative to a sensor. SOLUTION: A protection sensor 10 mounted in a vehicle has a unidirectional antenna 12 connected to a Doppler detection circuit 14, which generates an RF signal radiated by the antenna.
