Title: Welding apparatus equipped with feed synchronization part of weldment
Inventor: FUROHASHI TOSHIAKI
IPC: B23K37/00
Filed: 1978-08-14
Abstract: PURPOSE: To enhance workability as well as to heighten the quality of product by a mechanism  wherein the weldment being carried by a conveyor is accepted by a pusher device which is synchronized with the welding work speed before the welding work is started.   
     CONSTITUTION: On the drive shaft 23 which rotates in synchronization with the rotation of the  welding electrode drive shaft, rotatable cylinder 26 having prescribed grooves 24 provided on its  circumference and rotatable discs (cam plate) 36A and 36B are installed, and on the groove 24 of  the rotatable cylinder 26, one end of the first shaft 25 is geared while its other end is being attached on the support pusher 28, and the whole pusher device is formed by making movable plates 37  and 37B (rotatable with the shaft 23A as its rotation center) contact with the disc 36A and 36B.  By the rotation of the drive shaft 23, the first shaft 25 and the movable plate 28 proceed forward  by the first one half roll of the shaft 23, and its second half roll makes them retract rearward,  thus, the shaft 25 and the plate 28 make reciprocal movement. At the same time, the two pieces  make up and down movement by the second shaft 35A, 35B and support plate 38 which are  moved by the cam device consisting of the rotating disc and the moving plate. This means that,  the forward movement of the plate 28 makes the pusher 2 protrude upward which proceeds the  weldment to the electrode side at a prescribed speed, and the rearward movement of the plate 28  makes the pusher 2 retract down to restore to its original position.

Abstract: PURPOSE:To improve beam-condensing characteristics, particularly, coupling efficiency with an optical fiber, by forming a spheroidal indentation to a lead frame for an optical semiconductor chip loading section and forming a lens body integrally shaped with a sealing resin to a spheroidal shape of a locus of the same shape. CONSTITUTION:A spheroidal indentation 7 is formed to the top section of a lead frame 5 loading an optical semiconductor chip 1, the bottom is flattened, and the chip 1 is placed on the flat surface. The flat surface is formed so that the optical central section of the chip 1 such as the P-N junction section is arraned at one focal position of a spheroid at that time. A lens body 8 composed of a molding resin is formed to the optical front surface of the chip 1, but beam-concensing chacteristics are improved by forming the lens body 8 to a projecting lens shape having the external form of a locus of the same shape as the spheroidal indentation 7 of the top section of the lead frame 5. When a red light-emitting diode chip consisting of a base body such as a GaAlAs base body is used and the spheroidal indentation 7 and the lens body 8 are designed in conformity with the light-emitting section of the diode chip, optical coupling efficiency to an optical fiber 9 disposed in front of the lens body can be improved.

Such multilayered structure is formed by sputtering the above-mentioned materials 2 and 3 while a substrate 1 mode of alumina is rotated after the substrate 1 is heated to 350 deg.C. The entire thickness of such multilayered structure is controlled to 1-2mum, with thicknesses of the film 3 and 3rd film 4 being respectively set to 150-200Angstrom  which is about one tenth of the main constituent film 2. After the films of a positive temperature coefficient (PTC) thermistor are formed in such way, a 2-layer electrode of Ni 5a and Pt 5b is formed on the films by a sputtering method.

Title: Synthesizing system for switching signal output
Inventor: YOSHIDA RYUZO
IPC: G06F3/023
Filed: 1985-05-09
Abstract: PURPOSE:To simplify extremely the circuit constitution by connecting the diodes of the same number of switches in parallel to a port. CONSTITUTION:When the switch information on a switch group G1 is read, the control signal is sent to the group G1 from a computer. Each bit of the control signal is sent to a common connection terminal of switch groups G1-Gm. The diode D connected to the output side of the switch is biased forward and conducts to show '1'. While the diode D connected to a terminal where a switch S is opened is not biased and shows '0'. Then the switch S is connected to a data bus B via a port P and the information is also delivered to the bus B. While '0' is issued to the common connection terminal of other switch groups and therefore these diodes D are not conductive. Then each switch S is cut off from the port P.

Filed: 1989-04-18
Abstract: PURPOSE:To reduce a leaked magnetic flux in a head protruding window by providing a cancel magnet in a space between a yoke and a magnetism proofing cap. CONSTITUTION:A magnetism proofing cap 10 is formed by the magnetic material of comparatively low permeability such as cold-rolled steel, etc. Cylindrical cancel magnets 13a and 13b are fitted to yokes 9a and 9c and holds the space between the cap 10 and yokes 9a and 9c. Simultaneously, the magnets are magnetized so as to generate magnetic fluxes 20a and 20b against the direction of a leaked magnetic flux 19 in a head protruding window 11 of the cap 10. Namely, when the side end of a center pole 8 in first and second permanent magnets 6 and 7 is faced as an N pole, the cancel magnets 13a and 13b are magnetized with an inner circumference side as an S pole and an outer circumference side as the N pole. Thus, in the head protruding window 11, the magnetic flux is canceled. Then, it is not necessary for the cap 10 to use the material of the high permeability.

IPC: H04W56/00
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To smoothly switch the timing of a transmission signal by allowing a transmission section to generate a transmission signal indicating a medium timing between system clocks in a pseudo way from a generated transmission base band signal and sending the transmission signal. SOLUTION: A transmission timing control circuit 104 controls a transmission timing to be advanced or lagged so as to be coincident with a reception timing generated by a reception timing generating circuit 103. In the case of delaying the transmission timing by Ts, a switch 109 is closed and a switch 110 is open. Then the switch 110 is closed for an optional prescribed time and a sum of two transmission signals having a timing difference Ts of the system clock is sent. This is a transmission signal of a pseudo medium timing. When the signal is lagged further, a generating timing of the signal by a transmission base band signal generating circuit 106 is delayed by one clock Ts and the switch 109 is closed and the switch 110 is open and then the processing is conducted.
