Title: Switching system for optical transmission line
Inventor: FUJIKURA YASUHIRO
IPC: H04B10/03
Filed: 1985-04-11
Abstract: PURPOSE:To reduce the number of optical fibers to the minimum and, at the same time, to duplicate the optical fibers including an optical transmitting and receiving sections, by installing two optical fibers for ascending and descending as the optical transmission line of a currently used system and one optical fiber as the transmission line of a standby system. CONSTITUTION:When a currently used system operates normally, transmitting data are transmitted through the route of a changeover switch 106, optical transmitting section 100, optical receiving system 102, and changeover switch 108 on the ascending side and route of a changeover switch 109, optical transmitting section 103, optical receiving section 10, and changeover switch 107 on the descending side. If the ascending side optical transmission line becomes defective, the ascending side transmitting data are transmitted through the route of the changeover switch 106, optical transmitting section 100' of a standby system, optical switches 104 and 105, optical receiving section 103', and changeover switch 108 and the descending side transmitting data are transmitted through the same route as that at the normal time. When the descending side transmission line becomes defective, the optical transmission line of the standby system is used as a descending side transmission line.

Title: Button type alkaline battery
Inventor: WATANABE OSAMU
IPC: H01M50/193
Filed: 1982-05-07
Abstract: PURPOSE:To improve the leakageproofness of the captioned battery by using an annular gasket that increases the degree of crystallization by nylon 11 or 12 containing a specific amount of carbon black. CONSTITUTION:Nylon 11 or 12 containing carbon black by 0.05 to 1.0wt% is molded into an annular gasket by an injection molding machine or the like. Since the degree of crystallization of nylon 11 or 12 in thus obtained gasket is low, it is increased to 25 to 50% by heating and processing nylon 11 or 12 in the environment of vacuum, an inert gas, or water vapor. Even if the degree of crystallization is increased, however, the deformation of the gasket is prevented by the presence of carbon black. As a result, the fitting of the gasket in a negative electrode terminal block is performed properly and the leakageproofness of a button type alkaline battery is improved.

Title: Substrate formed with solder bump, ball solder setting device, and formation of solder bump
Inventor: MATSUZAKI AKIRA
IPC: H01L21/60
Filed: 1993-04-02
Abstract: PURPOSE:To provide a method for forming solder bumps suitable for mass production in which the work for forming solder bumps onto the surface of a substrate is facilitated by a method for holding a ball solder without applying any adhesive onto the surface of the substrate. CONSTITUTION:A ball solder setting device 18 is set horizontally with a ball solder setting holes 17 directing upward. Ball solders 7 having predetermined outer diameter are then fed to the setting device 18 where excess ball solders 7b are discharged through a ball discharge port 16 by means of a brush 19. Subsequently, a carrier substrate 20 is fitted integrally to an alignment frame 15 and turned over to drop the ball solders 7a onto the carrier substrate 20. The ball solder setting device 18 is then removed from above the carrier substrate 20 which is eventually subjected to heat treatment thus forming solder bumps on the carrier substrate 20.

Title: Current detector
Inventor: FURUTA SHIGEKI
IPC: G01R19/165
Filed: 1987-03-30
Abstract: PURPOSE:To accurately detect a deviation from a current value corresponding to the reference voltage of a load current at all times by providing a main MOSFET, a subordinate MOSFET, a detection resistance, etc. CONSTITUTION:When both MOSFETs 30 and 40 conduct by receiving a signal from a driving means 10, the majority of the load current to a load flows to the input terminal 35 of the main MOSFET 30 through many cells and an output terminal. The remaining part of the load current, on the other hand, flows through the input terminal of the subordinate MOSFET 40, a cell output terminal, and the detection resistance 50, which detects the inflow current and generate a detection voltage. This detection voltage and a voltage from a reference voltage generator 60 are supplied to a comparator 70 and compared with each other. Further, the resistance 50 is formed of a material which has negative resistance temperature characteristics. Consequently, the resistance value of the resistance 50 varies according to the negative temperature characteristics so that even if the MOSFETs 30 and 40 and resistance 50 vary in temperature, variation in the internal resistance value of the MOSFET 40 with temperature is canceled, so the detection voltage from the resistance 50 is held at the same value.

Title: Mold lubricant supply device
Inventor: TAKEDA KENJI
IPC: G03G15/20
Filed: 1989-03-31
Abstract: PURPOSE:To raise the operability of an oil bottle so as to prevent misoperation, to simplify the constitution of a device and to make the best use of oil by arranging a containing vessel in a position where mold lubricant running from a recovery vessel is received. CONSTITUTION:The containing vessel 5 is arranged in the position to receive the mold lubricant running from the recovery vessel 6. In this case, the mold lubricant is carried to the position of a supply member from the recovery vessel 5 by a carrying means 4, and is supplied to a fixing roller 1 by which the lubricant is brought into contact with a fixing roller 1. The remainder not used for fixing is recovered to the recovery vessel 6. The mold lubricant in the recovery vessel 6 returns to the containing vessel 5 positioned below the vessel 6. However, it is again carried by the carrying means 4 to supply for fixing. Consequently, oil splashing and roller offset due to misplacing of a string bottle and a disposed bottle and misoperation can be prevented, whereby operability (visual recognition and oil discard) in bottle replacement can be improved. Since the oil is consumed until the bottle becomes completely empty, it can be used effectively.
