Filed: 1994-03-09
Abstract: PURPOSE:To provide optical parts having the switching function of an optical waveguide. CONSTITUTION:A track part 30 is provided between a waveguide forming part 10 and a waveguide forming part 20. Then, a moving body B provided with the optical waveguide 43a is displaced along the track part 30.

Title: Continuous bar code marking system
Inventor: DAGURASU KUREIGU BOTSUSEN
IPC: B41J2/44
Filed: 1994-03-09
Abstract: PURPOSE: To constitute a method and apparatus for writing a bar code in a continuous pattern by adding a step for marking a substrate so as to obtain a serpentine pattern having a connection segment for alternately linking data segments at both ends. CONSTITUTION: A series of connection segments for linking adjacent bar code data segments are used. These connection segments are set to the ends of the data segments to suitably connect the data segments vertically. However, the connection segments may be actually patterns such as circular arc patterns or the like corresponding to the continuous operation of a laser. In order to provide continuity to a writing path, the connection segments are alternately arranged so as to obtain a serpentine pattern. Further, in order to accurately start the laser operation to a substrate, especially, in such a case that the substrate is plastic or metal, the start segment vertically extending outwardly from one end of a first data segment is used. Therefore, the effect of laser irradiation on the substrate is continued to become uniform.

IPC: B23K9/04
Filed: 1994-03-09
Abstract: PURPOSE:To prevent a defective welding due to the overheat of a base block by providing the base block where an end surface on the valve head side of a stock valve is abutted on and a cooling means of the base block on a stock valve holding means, and cooling the base block. CONSTITUTION:A stock valve A is diagonally held so that the valve head of a stock valve A may be opposite to a welding torch by a stock valve holding means 30. The valve head of the stock valve A is overlaid by the welding torch, and the valve is manufactured. A base block 45 is cooled by the coolant, and is prevented from reaching high temperature. An area reducing member 47d of the flow passage for the coolant is arranged on the reverse side part of the base block 45 to increase the flow speed of the coolant, ad the base block 45 is cooled at high cooling efficiency. Such a constitution prevents the defective welding due to the overheat of the base block 45, e.g. the reduction in the hardness, etc., of the overlaid part by the penetration of the alloy of the stock valve into the overlaid part.

Title: Recording or reading device and paper sucking device
Inventor: OKODA KEIJI
IPC: B65H3/08
Filed: 1994-03-10
Abstract: PURPOSE:To provide a sheet sucking device which is constituted to eliminate an electromagnetic pump, reduce the generation of vibration and noise, and reduce a cost by a method wherein a sheet is sucked to a sucker and separated therefrom through the generation and reduction of a sucking force along with the change of inner capacity of an internal space through deformation and drive of the moving part of a container. CONSTITUTION:Since, when a sucker 23 is separated away from a sheet S, a lever 7 is energized by the protrusion 9a of a cam 9 to pull a spring 12, the bellows 1a of a diaphragm 1 is compressed. In this case, the lower end of the lever 7 is moved over a lock lever 13 for locking. When the sucker 23 approaches a sheet 8, the protrusion 9a is moved through a position (b) to a position (c) and the lever 7 is locked to the lock lever 13. Further, when the sucker 23 is brought into contact with the paper S, a signal is generated from a photo coupler 21 and a solenoid 16 is electrically connected by a control unit CU. As a result, the lock lever 13 is released from locking, the lever 17 is rotated through the force of the spring 12 and stopped by a stopper 11. Thus, a bellows part 1a is expanded and the sheet S is sucked by the sucker 23.

Title: Pickup cartridge shifting device of video disk player
Inventor: KISO MATAICHIROU
IPC: H04N5/903
Filed: 1982-03-12
Abstract: PURPOSE:To eliminate the disorder of a reproduced picture which is due to an external impact, by shifting a pickup cartridge only when a vertical synchronizing signal is detected by the pickup cartridge. CONSTITUTION:A stylus 6 detects a video signal. A vertical synchronizing signal separating circuit 15 separates a vertical synchronizing signal from the reproduced video signal and delivers it to an AND circuit 16. At the same time, an angle sensor 13 detects the inclination of the arm of a pickup cartridge. When the inclination of the arm is larger than a fixed level, the sensor 13 delivers the output of detection to the circuit 16. The circuit 16 delivers a signal only when both a vertical synchronizing signal output and the detection output of the sensor 13 are supplied at one time. An amplifier 17 amplifies the signal given from the circuit 16 and feeds it to a servo motor 18. The motor 18 is driven by an amplifying signal and shifts the pickup cartridge.
