Title: Anode jointing device
Inventor: KOMATSU HIROSHI
IPC: H05B3/14
Filed: 1999-04-06
Abstract: PROBLEM TO BE SOLVED: To constitute an anode jointing device in such a way that the device can be provided with a carbon heater covered with a coating having a high abrasion resistance, a strong peel strength, high conductivity, etc. SOLUTION: An anode jointing device is constituted to joint a semiconductor substrate and a glass substrate fed as an assembly 25 formed by bringing their surfaces into contact with each other without using a adhesive. For this device, following items are provided: a DC voltage source 36, a first electrode 37 for impressing a DC voltage upon one side of the assembly 25, and a second electrode for impressing the DC voltage upon the other side of the assembly 25, a carbon heater 32 for heating the assembly 25, and an AC voltage source 35 for impressing an AC voltage upon the heater 32.

Title: Compressor
Inventor: YANO MIKIO
IPC: F04C28/24
Filed: 1982-06-09
Abstract: PURPOSE:To achieve conservation of energy, by eliminating excessive supply of coolant at the time of high-speed operation of a compressor by providing, at a suction port, a flow control valve which is actuated by the hydraulic pressure that is increased with the speed of rotation of a turning drive shaft and decreases the opening area of the suction port when the hydraulic pressure is high. CONSTITUTION:When a drive shaft 16 is turned at a high speed, hydraulic pressure is raised rapidly and oil is supplied from an oil passage 29 to a hydraulic pressure port 28 and urges the end face 27 of a valve body 22 disposed at a suction port 14, so that the valve body 22 is moved against the force of a spring 23. This causes relative displacement of the suction port 14 and a valve port 24, and the opening area of the suction port 14 is decreased. Here, the opening-area decreasing rate is increased as the speed of rotation of the drive shaft 16 is increased. Therefore, the discharge quantity is reduced as the speed of rotation of the drive shaft 16 is increased. With such an arrangement, it is enabled to achieve conservation of energy by keeping the amount of circulated coolant at a proper level and preventing excessive supply of coolant at the time of high-speed operation, for instance, in case that the compressor is driven by an automotive engine.

Title: Front side member structure of automobile
Inventor: NAMIIRI ATSUSHI
IPC: B62D25/08
Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To suppress the increase in weight of a car body so as to be resistant to input collection by forming a front side member by the connection of a front member of thin extruded material and a rear member of a thick extruded material, and bonding the lower end part of a strut housing to the connecting part of both the members on the front side member side surface so as to cover the connecting part. SOLUTION: A front side member (FM) 1 comprises a thin front member 2 and a thick rear member 3 connected thereto, and the distribution of sectional area coefficient to bending moment of FM 1 is large in the rear side with a connecting part 5 as the boundary. When various inputs are added to FM 1 to generate a bending moment in the whole body, the force of peeling the front member 2 from the rear member 3 in the connecting part 5 is dispersed to a food ridge 9 in the upper part or the whole upper roof through the in-plane of the lower end part 8 of a strut housing 7 bonded to the connecting part 5 and the whole strut housing 7 to suppress the generating stress of the connecting part 5 to a minimum. Therefore, the various inputs added to FM 1 can be surely supported while suppressing the increase in the weld length with a body and the body weight.

Title: Fuel injection system for internal combustion engine
Inventor: SHIRABE NAOTAKA
IPC: F02M67/02
Filed: 1990-04-17
Abstract: PURPOSE:To make the extent of differential pressure with pressure in fuel to be fed to a fuel injection valve, constant as well as to measure a fuel injection quantity accurately by means of only injection time by changing pressure in a nozzle chamber to atmospheric pressure substantially and positively at a period when fuel is sprayed into the nozzle chamber, and keeping it constant. CONSTITUTION:When an air injection valve 9 is not yet opened, a needle 26 goes forward and a valve part 27 takes a valve seat 24, thereby preventing compressed air from being jetted to an air injection chamber 29. At this time, simultaneously a pin 43 depresses a valve 34, making it separate from a valve seat 36, and the air injection chamber 29 is interconnected to an atmospheric open hole 39. Therefore a nozzle chamber 6 also comes to atmospheric pressure via a passage 30, an annular chamber 31 and a passage 18. Then, a fuel injection valve 8 is opened, and since injection of fuel into the nozzle chamber 6 is limited to only at a time when the air injection valve 9 is closed, the nozzle chamber 6 comes to the atmospheric pressure at this time. Accordingly, even if fuel is sprayed into the nozzle chamber 6, superfluous pressure escapes into the atmospheric open hole 39, so that the fuel injection valve 8 comes to spray the fuel into an atmospheric interspace all the time.
