Title: Consuming device for microwave
Inventor: DEGUCHI YASUSHI
IPC: H01P1/26
Filed: 1981-04-30
Abstract: PURPOSE:To eliminate the reflection of a microwave and to prevent an increase in size by equipping a coaxial cable for microwave consumption, made of a high resistance material, at the output end part of a coaxial cable for microwave propagation. CONSTITUTION:At the output end part of a coaxial cable 1 for microwave propagation, a coaxial cable 8 for microwave consumption using a high resistance body for a surface where a microwave comes into contact is equipped. The cable 8 is made of a metal of high resistance such as stainless steel, nickel chromium alloy, graphite, etc. In this case, a center conductor 10 need not be made of a high resistance material all the time, but an external conductor 11 should be made of a high resistance material because of radiation. Consequently, even when the input terminal of the cable 8 is formed at right angles to the propagation direction of a microwave, no reflection is caused and the device never increases in size. In addition, radiation efficiency is high.

Title: Heat-sensitive recorder
Inventor: SHIBUYA YASUAKI
IPC: H04N1/23
Filed: 1984-04-03
Abstract: PURPOSE:To reproduce a picture with high quality by preheating a headup to such a degree that generates no color with the reverse data of a using line, and eliminating the store variance between black and white data parts of a line. CONSTITUTION:The signals fed from a circuit 1 are transferred to an MODEM3 via a circuit network controller 2, and the picture data demodulated by the MODEM3 are stored in a line memory 4. These data are read out of the memory 4 with the prescribed timing and outputted to a driver 7 via a switch 6. The driver 7 drives a thermal head so that no voltage is applied to a heating resistor which responds to the black data of a head 8. Such a drive of the thermal head is carried out with all heating resistors of the head 8. Thus these heating resistors conduct and generate heat at a certain temperature and generate colors with the heat-sensitive recording paper 10.

Inventor: SUMI YUKINORI
IPC: H01L21/60
Filed: 1989-03-16
Abstract: PURPOSE:To maintain the strength of a tab lead for a long time, to reduce the failure of the lead and to improve the reliability of a semiconductor device by a method wherein a Cu plating is applied on a Cu material through a barrier metal and moreover, an Su plating is applied on the Cu plating to form a tab lead. CONSTITUTION:A barrier metal 30 consisting of Ni is plated on a material 21 containing Cu or a Cu alloy as its main component to cover. Then, a Cu plating 31 is applied thereon and moreover, an Sn plating 22 is applied thereon to form a tab lead 12'. In the tab lead 12' formed in such a way, a reduction in the strength due to the interface between the metal 30 and the plating 22 is not generated because the metal 30 is covered with the Cu plating and when the lead 12' is bonded with an Au/Sn alloy, a progression of embrittlement is decreased and the strength is held. Thereby, the strength of the lead 12' is maintained for a long time, the failure of the lead 12' is reduced and the reliability of a semiconductor device is improved.

Title: Resin pipe and its butt fusion joining method
Inventor: MIZUKAMI TSUYOSHI
IPC: B29K101/12
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To form a uniform bead in a short time, and to provide sufficient bonding strength by providing an electric heating body on a pipe end face or in the vicinity thereof, and forming a fused part to be the pipe end face. SOLUTION: An electric heating body 3 such as a Nichrome wire and a carbon fiber sheet is embedded in the vicinity of a pipe end face 2 of a resin pipe 1 by one turn along the pipe circumference, and an end part of the electric heating body 3 is projected outside the resin pipe 1 for energization. The pipe end face 2 of the resin pipe 1 is butted to a pipe end face of a resin pipe 4 without the electric heating body 3, the electric heating body 3 is energized, and the pipe end face 2 is heated and fused for welding. The electric heating body 3 is not removed after heating, but left behind on a fused part 5 after welding. Because the removing work of the electric heating body 3 is dispensed with, pipes are welded in a short time, and the fused end face is not deformed, forming a uniform bead.  Because the molten resin at the end face to be bonded is not exposed to the atmosphere, the bonding strength is neither degraded nor non-uniform.

Abstract: PURPOSE:To prevent the fall of residual toner and the subsequent contamination of other parts at the time of separating a cleaning unit from the surface of a drum for maintenance or the like by providing a falling toner recovery member capable of functioning, upon releasing the cleaning unit. CONSTITUTION:A bracket 68 and a toner recovery member 67 are held on a rail 6a fixed to a drum side plate 1a, and constituted as to be capable of being drawn out at the time of a maintenance work. If the change of a cleaning blade 61 is desired, for example, at the time of periodical maintenance, a cleaner case 64 is released temporarily from a photosensitive drum and, then, drawn out from a body along a rail 6b. In this case, however, toner deposited between the cleaning blade 61 and a raking sheet 65 is left on the surface of the photosensitive drum. As a result, the toner falls down, due to gravity and received with the toner recovery member 67 for subsequent storage on the bracket 68. According to this construction, a service engineer is only required to dispose of the toner on the bracket 68, every time the cleaner blade 61 is changed.

Abstract: PURPOSE:To attain a logic circuit contrived to be operated by a single power supply by providing a bias generating means so as to boost a source potential of a depletion field effect transistor(TR) to a positive potential larger than a threshold voltage of the said TR. CONSTITUTION:With a power voltage VDD supplied to a logic circuit 21, a constant current decided by a load FET 6 flows to a diode 25 via a driver FET 5 or a bypass means 22. That is, while the FET 5 is turned on, a constant current decided by a FET 6, that is, a drain current of the FET 5 flows to a diode 25. While the FET 6 is turned off, a constant current decided by the FET 6 flows to the diode 25 via the means 22. A forward voltage drop in response to the constant current is caused across the diode 25. Since the anode of the diode 25 is connected to the source of the FET 5, the source of the FET 5 is boosted to a positive potential by the forward voltage drop of the diode 25 with respect to a power line VEE.
