Patent JP-S63160383-A (JP)
Title: Manufacture of semiconductor device
Inventor: NISHII KATSUNORI
IPC: H01L29/872
Filed: 1986-12-24
Abstract: PURPOSE:To manufacture an exceedingly reliable MESFET that is free from fluctuations due to heat treatment since the implementation of threshold adjustment by forming thinly a Schottky metal where no solid phase reactions take place together with a chemical compound semiconductor substrate between the Schottky metal where the solid phase reactions are liable to occur together with a compound semiconductor and the substrate. CONSTITUTION:An active layer 2 is formed by an ion-implanting technique into GaAs and source and drain ohmic electrodes comprising AuGe/Ni/Au are formed on the active layer 2. Then a gate electrode opening part 5 is formed with photoresist 4. The first Schottky metals 6 such as Ti where no solid phase reactions take place together with GaAs throughout the surface on the gate electrode opening part 5 and photoresist 4 is vaporized and the second Schottky metal 7 such as Pt where the solid phase reactions take place together with GaAs is vaporized on the above Schottky metal 6. After that, the first and second Schottky metals on photoresist 4 are removed with a lift-off technique and a gate electrode is formed. Subsequently, a solid phase reaction part 9 together with Pt and GaAs is formed by heat treatment and threshold voltage adjustment is carried out. The formation of thin Ti where no solid phase reactions take place together with GaAs makes reaction speed of the solid phase reactions with Pt and GaAs slow.

Title: Valve device and pump for transmission
Inventor: AGNER IVO
IPC: G05D7/01
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To feed a large volume flow to a pump with small loss by providing a pressure return face having split hydraulic resistance on a flow adjusting piston, and arranging the pump and a valve nearby. SOLUTION: The volume flow Q from a pump unit has a pressure drop through a baffle 21. The pressure p0 prior to the baffle 21 is fed to a pressure chamber 13 and is applied to whole the right end face 43 of a flow piston 15. The pressure p1 generated behind the baffle 21 is applied to the left circular face 31 through circular faces 45', 45", 45"' and a diaphragm 47 and generates the force to move the piston 15 to the right. Balance of force is kept between the exciting force on the right side of the piston 15 and the exciting force on the left side. When the volume flow Q and the differential pressure (p0-p1) of the baffle 21 are increased, the piston 15 is moved to the left against the force of a coil spring 17. The right end face 43 finally opens an outflow port 97 by this motion, and a hydraulic communication path between discharge and suction regions is opened.

Filed: 1992-11-25
Abstract: PURPOSE:To prevent plastic deformation of a bimetal by fixing a middle part in the longitudinal direction of the bimetal, and supporting a spring member between a latch movable member and an end part on the opposite side to a latch movable member driving side of the bimetal. CONSTITUTION:When abnormal current is not supplied, a stop member 9 is stopped by a latch movable member 13 in a latch condition. When the abnormal current is supplied, one end part 15a of a bimetal 15 which is fixed to a terminal plate 16 at a middle part in its longitudinal direct is flexed counterclockwise, while an end part 15b on the other side is flexed clockwise, so the latch movable member 13 rotates counterclockwise against spring force of a spring member 14, and a counter part 9a for the stop member 9 is removed from a stop part 13a of the latch movable member 13 for performing trip action. In case a temperature rise occurs at the bimetal 15, therefore, both sides of its middle part are flexed, so if tolerance of the bimetal 15 is reduced, stress applied on the bimetal 15 by the spring member 14 is also reduced, thereby the stress applied on the bimetal 15 is hard to exceed its tolerable stress.

Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of defective printing by immediately detecting the occurrence of skew of a paper sheet between an image forming part and a fixing part of an image forming device. SOLUTION: A side fringe part 312D of an upper plate 312 comes into contact with a lower face of a continuous paper 10 due to energizing force of an energizing member 320. In a condition in which skew does not occur on the continuous paper 10, all the microswitches 340 are maintained in a condition in which their operation piece 342 is at a position where it is pressed down by the continuous paper 10 and all the microswitches 340 are turned on because the continuous paper 10 is conveyed in a condition in which it is in contact with sections in all regions in the longitudinal direction of the side fringe part 312D of the upper plate 312. When skew occurs on the continuous paper 10, the operation piece of the microswitch 340 in a section where the continuous paper 10 floats from the side fringe part 312D oscillates to a protrusion position, and the microswitch 340 is turned off.

Abstract: PROBLEM TO BE SOLVED: To improve the efficiency and the degree of freedom by using a system memory as a cache memory by reporting the existence of specified data block in the cache memory through a bus system to a program. SOLUTION: While using one part 19 of system memory 11 as cache memory, a dedicated cache manager circuit 30 is connected through an interface different from the interface, with which a processor or the system memory is connected to the bus system, to the bus system. When an operating system 18 requests access to any specified data block, a cache manager 30 investigates whether this specified data block exists in the cache memory 19 or not by checking an internal look-up table. When the existence of specified data block in the cache memory 19 is discovered, the operation for returning a sign showing 'presence in cache' through the bus system to the program is performed.

Abstract: PURPOSE:To detect the leading and terminating ends of a tape more quickly when the tape feeding is stopped at the end of the tape by providing a control means for shortening the detecting timing of the leading and terminating ends of the tape after the second time by a detecting means when the leading and terminating ends of the tape are detected with the detecting means. CONSTITUTION:A control means for shortening the detecting timing of the leading and terminating ends of a tape after the second time by a detecting means when the leading and terminating ends of the tape : are detected at the first time by the detecting means is provided. For example, the leading and terminating ends of the tape are transparent. At the part other than the leading and terminating ends, of the tape, however, the signal from a light emitting diode 1 is screened with the tape, and the signal does not reach a light receiving transistor 3. The signal is not inputted into a control device 4. Conversely, the signal from the light emitting diode 1 is inputted into the light receiving transistor 3 through the leading and terminating ends of the tape. The signal is inputted into the control device 4. Therefore, whether the parts are the leading and terminating ends of the tape or not can be discriminated by the control device 4. Thus, the erroneous judgment is prevented, and the effective detecting operation of the leading and terminating ends of the tape can be performed in a short time.
