Title: Sublimation-type thermal transfer recording medium
Inventor: KAMIMURA HIROYUKI
IPC: B41M5/382
Filed: 1988-07-15
Abstract: PURPOSE:To enable multi-time printing at high speed and with high density by dividing an ink layer into a dye-supplying layer and a layer contributive to transfer, which are located in that order from the side of a base, and incorporating a specified compound in each of the two layers constituting the ink layer. CONSTITUTION:An ink layer 2 comprising a sublimable dye dispersed in e resin binder is provided on a base 1, and the ink layer 2 is divided into a dye-supplying layer 4 and a layer 5 contributive to transfer, which are located in that order from the side of the base 1, and are made to comprise a compound shown in formulae (I), (II), (III), (IV) or (V). The ink layer 2 of such a thermal transfer recording medium is brought into contact with a resin coat layer of an image-receiving paper 3, and heating energy is applied thereto from the recording medium side by a thermal head 6, thereby printing. Upon this operation, the transfer by sublimation of the dye from the contributive layer 5 to the paper 3 and the supply by diffusion of the dye from the dye-supplying layer 4 to the layer 5 are performed efficiently, so that the density of transferred images is not lowered even when printing is repeated many times, and it is possible to enhance the density of the images being transferred at high speed and with high sensitivity.

Title: Element parts for printed substrate and their manufacture
Inventor: HASUNUMA MASAHIKO
IPC: H05K3/24
Filed: 1985-08-09
Abstract: PURPOSE:To prevent IC lead wires from being shorted even if they come in contact with the upper edge of the recessed part, by removing gold-plating, which is performed on an IC-mounted recessed part, at least down to a little lower part from the upper edge of the sidewall of the recessed part. CONSTITUTION:A square shallow recessed part 2 is formed at the central part of the upper surface in a square substrate 1 composed of glass-fiber reinforced plastics, and gold-plating 6 is performed on the inner surfaces of the recessed part 2, containing the whole bottom surface 3 and four side surfaces 4, over the position slightly lower than the upper edge 5. Besides, many gold-plated fine circuits 7 are formed on the upper surface of the substrate 1 surrounding the recessed part 2, externally at the position a little apart from the upper edge 5 of the recessed part 2, and respective fine circuits 7 are connected with the upper ends of many lead pins 8, which pass through the substrate 1 and project below the substrate. Because gold-plating is not performed on respectively neighboring parts at the upper edges 5 where two side surfaces of the IC- mounted recessed part 2 cross at right angles, IC lead conductors are prevented from being shorted even if they come in contact with the upper edges.

Title: Antenna tracking system
Inventor: NAKAJIMA SHIGEO
IPC: G01S3/42
Filed: 1982-10-08
Abstract: PURPOSE:To obtain the angular information with high accuracy, by extracting out of a demodulating circuit the information about the number of pulses which varies in response to the change of S/N of a received signal which is due to a directional shift of an antenna and counting the result, and using the time changing value with time of the calculated value standardized by the signal time occupying factor as a control signal for tracking the antenna. CONSTITUTION:The reproduced carrier phase, etc. of a demodulating circuit 3 is set by deviating intentionally from the optimum value so that the code error factor P2 of a reproduced data series is made larger than the code error factor P1 of a demodulating circuit 2. When the factor P2 is set 10<2> times as large as the factor P1, the output pulse number of an exclusive OR circuit 4 is approximately proportional to the P2 and therefore to the P1. While the angle shift information on an antenna can be obtained by detecting the time difference of the value obtained by counting the number of pulses at a point A every fixed period since the P1 is a function of the S/N of an input signal. For a signal in intermittent non-signal state in terms of time, the counting for the output pulses of the circuit 4 is discontinued by a standardized counting value generating part 16 for a period no signal exists.

Abstract: PURPOSE: To improve workability, and reduce cost without using a gold wire by printing and forming patterning whose central part is composed of neck- shaped solder cream between copper foil electrodes on an insulating film. CONSTITUTION: A solder cream pattern 14 where electrodes 12 and 13 which are oppositely arranged so as to separate from each other and are composed of copper foil are electrically continued with each other, is printed and formed on an insulating film 11. Since a central part 14a of the pattern 14 is thinly formed in a neck shape, when a large electric current flows between the electrodes 12 and 13, solder of the central part 14a melts, and it is disconnected by being pulled by both electrodes due to surface tension, and both electrodes are electrically discontinued with each other. Projecting parts of the electrodes 12 and 13 from the film 11 are formed external terminals. Normally, a part of the electrodes 12 and 13 and a surface of the pattern 14 are sealed by resin, and are cut off from an external part.
