Patent JP-H04340302-A (JP)
Title: Controller for electric vehicle
Inventor: MIYAZAKI REI
IPC: H02P27/06
Filed: 1991-05-14
Abstract: PURPOSE:To suppress production of heat as a whole by stopping a part of converter and driving another part of converter with maximum output thereby supplementing the deficiency of power when the required power of a motor driving circuit is lower than the maximum output power of a converter group. CONSTITUTION:An AC high voltage is taken in from a pantograph PAN through a circuit breaker CB and stepped down through a transformer T to be fed to converters CV1, CV2. DC outputs of the CV1, CV2 are connected in parallel in order to drive an inverter IN to produce VVVF power for rotating a motor M. Assuming Po is required power of the IN, P1 and P2 are powers to be born by the CV1 and CV2 respectively, and P1m and P2m are the maximum output powers of the CV1 and the CV2 respectively, the CV2 is stopped if Po < P1m whereas the CV1 outputs P1m and the CV2 bears the deficiency of power if Po > P1m. A cooling mechanism is installed closely to the CV1. Consequently, cooling efficiency is enhanced resulting in suppression of total heat production.

IPC: H01L21/338
Filed: 1990-04-25
Abstract: PURPOSE:To make it possible to increase gate and drain breakdown strengths even by a deep gate recess structure by a method wherein a second step recessed part is formed in a thickness between the bottom of a gate recess and a non-doped GaAs layer and a gate electrode is formed in the gate recess. CONSTITUTION:A non-doped GaAs layer 3 is grown on an N-type GaAs layer 2 grown on a semi-insulative substrate 1 and source and drain electrodes 4 and 6 are respectively formed in etching opening parts obtainable by etching the layer 3. The layer 3 is etched between the electrodes 4 and 6 in the thickness or thicker of the layer 3 to form a gate recess into the form of two steps and a gate electrode 5 is formed in the gate recess. Thereby, the layer 3 on the layer (active layer) 2 has the deep gate recess for facilitating deposition and lift-off processes in the formation of the gate electrode and while the thickness of the gate electrode is reliably held, gate and drain breakdown strengths can be increased.

IPC: H02J13/00
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To accurately evaluate a power system by using an evaluation index obtained by quantitatively considering the cost incurred by a loss at the time of a defect when a route is cut off and on the other occasions than when the route is cut off and the total power generation cost of normal times.

Title: Electronically controlled fuel injection device for internal combustion engine
Inventor: NAKANIWA SHINPEI
IPC: F02D41/00
Filed: 1986-05-15
Abstract: PURPOSE:To prevent production of a stepped sudden change in a fuel injection amount, by a method wherein, when a main fuel injection amount set means is switched to an injection-amount-for-acceleration set means, based on a set fuel injection amount, an injection amount for acceleration is corrected. CONSTITUTION:In a control unit 5, a main fuel injection amount set means sets a fuel injection amount based on the detecting values of an airflow meter 2 and a rotation speed sensor 1. After the acceleration state of an engine is detected, a fuel-injection-amount-for-acceleration set means sets a fuel injection amount based on the detecting values of a given time throttle valve opening sensor 3 and the rotation speed sensor 1. In which case, during switching of the two set means, a deviation between fuel amounts set by the two set means is determined for memory. Based on the stored deviation, a fuel injection amount set by the fuel-injection-amount-for-acceleration set means is corrected based on the stored deviation. This constitution enables reduction of a fuel injection amount deviation during switching of the fuel injection amount set means.

Title: Recording method of digital information signal
Inventor: OOSAWA HIDEKAZU
IPC: G11B20/18
Filed: 1983-06-18
Abstract: PURPOSE:To intensify the error correlation between symbols and to increase the probability to become erroneous for both symbols by recording the symbols forming a word at prescribed positions. CONSTITUTION:The even and odd words L and R are divided into two symbols A, B, etc. Then the symbol B is delayed by a delay element of a corresponding delay element grop 2, and symbols A and B are delivered alternately via a switch 3. An odd word is furthermore delayed by a corresponding delay element of a delay element group 4, and odd and even words are alternately delivered to undergo the read Solomon coding through a C2 coder 6. Thus the symbols A and B contain code bits, and these opposite two symbols A and B are recorded adjacently to each other on the same track via a delay element group 7 which makes these symbols series for each channel, a shift register 8, a switch circuit 9 and a coder 10. In this case, the recording is performed so as to intensify the error correlation between the symbols. This increases the probability for a fact that both symbols become erroneous at a time. Thus the error correcting capacity is improved.

Abstract: PROBLEM TO BE SOLVED: To secure the desired coating quantity of die bond paste, to mount semiconductor chips with desired accuracy and to improve the reliability of parts. SOLUTION: In this device, while a nozzle 17 for discharging die bond paste 6 is made to approach a lead frame, the nozzle 17 is pressurized to discharge the die bond paste 6 from the nozzle 17 and is stuck on the lead frame. Then, the nozzle 17 is separated from the lead frame and while keeping a state in which the lead frame and the nozzle 17 are connected, the die bond paste 16 is extended. Then, the nozzle 17 is evacuated to suck the die bond paste 6 from the nozzle 17 and cut it. Then, furthermore, the nozzle 17 is separated from the lead frame. In this way, when the die bond paste 6 is applied, the desired coating quantity and the coating form are secured and the time that elapses before cutting can be shortened.

Filed: 1980-08-13
Abstract: PURPOSE:To obtain a dot with uniform type concn. even if an armature gap is not adjusted exactly in an impact type dot printing head, by forming a magnetic circuit driving the armature into a magnetism leakage type. CONSTITUTION:A hammer 2 having a dot printing member 1 mounted to a leading end thereof is forked into two branches in the vicinity of a center part thereof and other ends thereof are again joined to fix the armature 3 comprising a ferromagnetic material and integrally molded with a support member 4 having a hinge part 5. Further, a coil 7 is fixed to the support member 4 by a mold 8.
