Title: Laser beam welding method
Inventor: SHINONAGA HIDEYUKI
IPC: B23K26/32
Filed: 1989-11-08
Abstract: PURPOSE:To easily exhaust steam in a welding part to an outer part and to prevent hunting by supporting one pair of welding members while keeping inclination so as to be to <90 deg.C angle to the horizontal plane and allowing the irradiating direction of the laser beam to the welding line to be lower than the angle of the inclination. CONSTITUTION:Since the welding members 10, 11 are inclined to the horizontal plane, the large quantity of shield gas injected from a nozzle 5 flows to slanting direction shown by the arrow mark C. Therefore, the steam generated from the welding part is difficult to be stagnated in the vicinity of the joining parts of the parts 10b, 11b being apart from bending parts 10a, 11b, and the welding part can be protected from the steam generated in the welding part. Further, since the irradiating direction of laser beam is inclined to the welding line X, melting depth (f) from the welding line X is made to shallow to melting depth (e) to the irradiating direction. Therefore, the width of bead is extended and the steam of molten part is easily exhausted to the outer part and blow hole is extremely made to be small and further, since the pressure of the shield gas can be made to low, the generation of hunting bead can be restrained.

Title: Programming method
Inventor: SHIMOZATO TAMOTSU
IPC: G06F9/06
Filed: 1990-10-26
Abstract: PURPOSE:To realize speedy immediate processing control with limited storage capacity by previously developing control data required for the processing of a control program and state discrimination data in a RAM area. CONSTITUTION:A controller 701 and a controlled device 703 are connected in a control signal table 702 so as to constitute hardware. Control data at individual timing written as compressed control information on the program and discrimination condition data are developed in a RAM address which is previously and collectively synchronized with a timing number in spared time at processing time. After control starts, control data is obtained only by referring to the having read timing number and the RAM address, and the controlled device 703 is successively and immediately processing-controlled. Thus, immediate processing time can be speeded up and the capacity of a program memory can be made small.

Title: Switching noise reduction circuit for magnetic recording and reproducing device
Inventor: FUJIWARA TAKU
IPC: G11B20/02
Filed: 1989-11-07
Abstract: PURPOSE:To reduce the switching noises by producing a sine wave compensating signal which is approximate to the amplitude and the cycle set before omission of a reproduced signal and inserting it to the omitted part of the signal. CONSTITUTION:A compensating signal generating circuit 7 detects the amplitude of a single cycle and the cycle set right before a single cycle of a demodulated signal 8 for each cycle and produces a sine wave compensating signal 7a having the average amplitude and the same cycle equal to the detected one. Both the amplitude and the cycle of the signal 7a are updated for each cycle of the signal 8 and approximated to the amplitude and the cycle set before omission of a reproduced signal. If the signal 8 is omitted, a holding pulse 5a is inputted to the circuit 7 from a holding pulse generating circuit 5. A holding circuit 6 holds the compensating signal obtained at the time of omission. Then an output sound signal 9 is transmitted in place of the omitted part of the signal 8. Thus the omitted part of the signal 8 is compensated with an approximated sine wave and therefore a signal approximate to the original one is obtained. Then the occurrence of noises is reduced.

Title: Method for laying long cv cable
Inventor: OSOZAWA KYOJI
IPC: H02G1/06
Filed: 1994-11-25
Abstract: PURPOSE: To easily lay a long CV cable while connecting sections are maintained in highly reliable states by forming connecting sections by connecting the conductors and insulators of cables to each other at a plant and obtaining a partially fabricated long cable by putting tentative protective tubes on the connecting sections, and then, finishing the connecting sections by exchanging the tentative protective tubes with proper protective tubes after the partially fabricated long cable is carried to and laid at a job site. CONSTITUTION: CV cables 1 and 1' are tentatively connected to each other at a plant. At the time of connecting the conductors 2 and 2' of the cables 1 and 1' to each other, a segment-wise welding method is adopted so as to make the finished outside diameter of a tentative connecting section as small as possible. When a molded insulator 6 is formed by using the EMJ method between the penciled end faces of insulators 3 and 3' on the conductor connecting section 5. Therefore, a highly reliable molded insulator 6 can be obtained by suppressing the mixture of foreign matters and occurrence of voids. In addition, since the insulator 6 can be protected with a tentative protective tube 11, the long cable obtained by connecting the cables 1 and 1' to each other can be transported and extended even when the cables 1 and 1' are tentatively connected to each other.

IPC: A44C25/00
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To provide an ornament which can be returned to the finished form (original form) when mounting on a neck or chest, even if any plastic deformation thereof is caused during the preservation, the mounting process or the like. SOLUTION: A wire 2 of a wire necklace 1 forming almost a double ring with ends is made of a shape memory alloy having a nature of returning to the original form from a deformation at a specified temperature near a body temperature. As a result, even when the wire 2 is under a plastic deformation before or during the mounting of the necklace, the wire 2 is cooled or heated by the user's body heat and returned to the original form at a specified temperature. Thus, the deformation is eliminated thereby keeping appearance unchanged in use.

Title: Power switching device
Inventor: MORI SADAJIRO
IPC: H01H9/36
Filed: 1988-11-18
Abstract: PURPOSE:To shift an arc quickly from a movable contact point to a commutation electrode and reduce the wear of the movable contact point by constituting the commutation electrode with a magnetic substance and causing the ingress of the movable contact in the hollow part of the commutation electrode. CONSTITUTION:A movable contact 11 is so constituted as to enter the notched part of a commutation electrode 22. When a fixed contact point 13a and a movable contact point 11a are opened with an operation coil 5 kept electrically alive, an arc is generated between both contacts points 13a and 11a. When a gap between the aforesaid electrodes 13a and 11a is widened with the passage of time and the movable contact 11 is ready to enter the notched part of the commutation electrode 22, a strong magnetic field works upon the arc because the commutation electrode 22 is made of a magnetic substance, thereby generating a driving force at right angles with the flow of the arc. As a result, the arc can quickly shift from the movable contact point 11a to the electrode 22. Furthermore, the arc is attracted by an arc-extinguishing grid 21 and extinguished. This arc extinction completes a circuit breakage. As the arc quickly shifts to the commutation electrode 22, the wear of the movable contact point 11a is small.
