Title: Transfer method to reduce percentage of defect
Inventor: OSADA TATSUKI
IPC: B44C1/16
Filed: 1979-10-30
Abstract: PURPOSE: To reduce the percentage of defect such as ununiformity of shading of a color, pinholes and others in a transfer method wherein a transfer sheet on which a desired picture pattern is printed in a paint or ink containing a pigment is put on an object to perform transfer printing, by repeating transfer.  
     CONSTITUTION: When, for example, a cylindrical molded article to be subjected to transfer printing has a circumferential length of l, the transfer paper has a picture pattern layer 3 having a length of 2l. On a substrate sheet 1 are formed a release layer 2, the picture pattern layer 3, and an adhesive layer 4 by the known method. Using this transfer paper, the molded article, after it has been subjected to transfer printing, will have a double printed structure as shown in cross section. In this case, it is necessary to register the picture pattern layer 3 in the double structure. Thus, ununiformity of shading of a color, pinholes and others that would be resulted by single transfer printing hardly occur.

Title: Planetary feeder of welding wire
Inventor: KAWASAKI TOSHIHIRO
IPC: B65H51/10
Filed: 1980-10-07
Abstract: PURPOSE:To facilitate the loading of new welding wires through releasing the connection between a retaining member and a pressing member, by operating the evacuation mechanism from the outside of the protective cover, in the planetary feeder of welding wires. CONSTITUTION:When a cylindrical cam 17 is rotated counterclockwise by operating a handle 19 of the evacuation mechanism, a pin 15 is abutted to the inclined surface between a wide groove part A and a narrow groove part (a) of a cam groove 171. At this time, the pin 15 is restrained against the direction Y by a pierced  hole 161 of a protective cover 16, and moves along the direction X2 and enters the narrow groove part (a). Therefore, the pin 15 is displaced by DELTAx in the direction X2,  at the same time, a spring receiving member 13 and a pressing member 11 are also  displaced by DELTAx through resisting the force of a spring 14, and thus, the connections between retaining members 10, 10 and the pressing member 11 are released. More  over, holding levers 6, 7 are put in freely rotative state around the pivot of a sup  porting member 1. When a welding wire 24 is inserted into a through hole 103, a  space between planetary rings 8, 9 is expanded and the welding wire 24 is loaded, because the holding levers 6, 7 can rotate freely. After the welding wire 24 is loaded,  the cylindrical cam 17 is returned to the original condition, then the wire 24 is fed.

Title: Apparatus for preventing electrostatic breakdown of semiconductor device
Inventor: TAKIGAWA AKIRA
IPC: H01L21/822
Filed: 1984-07-11
Abstract: PURPOSE:To absorb both positive and negative surge pulses by forming an n<+> type buried layer as a protection resistance and using a junction diode composed of the n<-> type region and the p type diffused region. CONSTITUTION:When a forward surge pulse enters the electrode in the input terminal side, a voltage drops due to a resistance while a surge current flows into the n<+> type buried layer 5. Thereby, an input voltage is clamped to a value which is equal to a breakdown voltage of the p-n junction diode D1 between the n<-> type region 6a and p type region 9. Namely, holes are implanted to a low potential p type layer 9 from the n<-> type region 6a, causing a current I1 to flow and absorbing a surge pulse. A backward surge current operates the p-n junction diode between the n<-> type region 6a and the p type diffused layer 9 and an input voltage is clamped to a voltage (GND-VF) which is equal to a difference between the ground voltage and forward voltage VF of diode, causing electrons to be implanted to the side of p type diffused layer 9 from the n<-> type region 6a.
