Title: Fuel feeder for internal-combustion engine having turbo- charger
Inventor: SHISHIDO KAZUYA
IPC: F02D41/30
Filed: 1983-04-12
Abstract: PURPOSE:To control the fuel injection accurately and to reduce noise of fuel pump by providing a fuel pump having variable delivery, fuel pressure adjusting means and a fuel pressure sensor in the fuel system including an injector. CONSTITUTION:A fuel pump 1 will feed fuel into an injector 5. A fuel pressure adjusting means 6 has a pressure regulator 7 and an orifice 8.

Title: Undervoltage relay for generator
Inventor: TAKAHASHI TORU
IPC: H02H3/24
Filed: 1995-03-23
Abstract: PURPOSE: To obtain an undervoltage relay for generator which is not tripped erroneously by an abnormality on the outside of yard but tripped quickly at the time of undervoltage. CONSTITUTION: The undervoltaqe relay 27 is connected with the secondary of an instrument transformer PTG and delivers a trip command TG through a normal close contact B, when a detected voltage VD is lower than a set level, to interrupt a circuit breaker 52G. A current detection coil C, connected with the secondary of a current transformer CTG, opens the normal close contact B when a detected current iD exceeds two times of a rated current iS. Upon occurrence of short circuit fault on the outside of yard, a circuit breaker 52R on the outside of yard is opened but since the contact B is opened by means of the coil C, trip command TG is not delivered to the undervoltage relay 27 in the yard. Consequently, the circuit breaker 52G is held in closed state thus sustaining power supply to loads L1 , L2 from a generator G.

Title: Lithium battery
Inventor: KIZAKI TAKASHI
IPC: H01M2/16
Filed: 1980-05-16
Abstract: PURPOSE:To reduce the internal resistance of a lithium battery by using a solid electrolyte which conducts lithium ions as a separator, which is impregnated with electrolyte. CONSTITUTION:Either a solid electrolyte such as lithium iodide or lithium nitride which conducts lithium ions, or a mixture of lithium iodide and lithium nitride is used as a separator which is interposed between active materials, and the separator which is interposed between active materials, and the separator is impregnated with electrolyte. For instance, a positive active material such as manganese dioxide is pressed and molded by using a metal mold, before lithium iodide is placed in the  same metal mold and is pressed, thereby a unified tablet consisting of a positive  electrode 2 and a separator 3 being formed. This tablet, next, is impregnated with  an elctrolyte, which is prepared by dissolving lithium perchlorate in propylene  carbonate before the solution is saturated with lithium iodide. After that, a lithium  negative electrode 4 is placed opposite to the tablet, thereby a lithium battery being  constituted. The separator 3 and the positive electrode 2 may not be unified. Owing  to the above constitutuion, the internal resistance of the battery can be decreased,  and the process of assembling the battery can be simplified.

Title: Medical guide wire
Inventor: HASHIMOTO TERUO
IPC: A61M25/01
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To provide a guide wire which facilitates the production thereof while ensuring a basic function thereof. SOLUTION: This guide wire has a guide wire body 2 comprising a high tensile linear material and having a tapered part 5 which is tapered gradually toward the tip of a tip part thereof and a superelastic alloy wire 4 bonded by an adhesive 3 on the tapered part 5 of the guide wire body 2 extending by a specified length along it. The use of the adhesive for integration between the guide wire body 2 and the supperelastic alloy wire 4 hinders the generation of heat during the integration of both 2 and 4 to prevent the impairing of the nature of the superelastic alloy wire 4 while the working manhour can be reduced by simplifying working itself. Moreover, the use of the adhesive limits the costly superelastic alloy wire 4 to partial use thereby achieving a reduction in costs.

Title: Circuit for preventing external disturbance over signal transmission system
Inventor: INOUE MASAHIRO
IPC: H04L7/027
Filed: 1985-03-29
Abstract: PURPOSE:To obtain a stable internal clock signal even if power source noise takes place by providing a gate controlled by an internal clock signal control means, an internal clock signal generating means, a frequency detecting means for an external clock signal and a phase detecting means. CONSTITUTION:The frequency detection circuit 62 detects the frequency of the external clock signal T for synchronization from a power supply synchronization circuit 5 and when a signal T entering the phase detection circuit 63 is within the range of phase error, the circuit 63 detects the phase of the signal T. A control circuit 64 initializes the internal clock signal CLK generated in the internal clock signal generating circuit 65 by using the phase and frequency detected in this way. The control circuit 64 controls the input of the signal T to a gate 61 by using the signal CLK. When the signal T is inputted, the gate 61 is opened only within a permissible error range for the expected time. Even when the gate 61 is closed and the signal T is inputted to the gate 61 due to noise, its input is neglected and the signal CLK is held.
