Title: Fuel injection nozzle for internal combustion engine
Inventor: TADA RYOICHI
IPC: F02M61/18
Filed: 1995-03-08
Abstract: PURPOSE: To improve the cooling effect of a fuel injection valve in a high- temperature environment. CONSTITUTION: An orifice plate 52 fixed on the outlet surface of the cylinder hole 8 of a valve body 26 by welding is integrally molded by using a metal having excellent heat transfer properties and comprises a plate part 61 and a cylinder part 62. Orifices 54 and 56 extending through in the direction of the thickness of the plate part 61 are communicated with the cylinder hole 8. The cylinder part 62 is functioned as a cylindrical cooling fin protruded in a direction in which the cylinder hole 8 is extended from the outer edge part of the plate part 61. A sleeve 71 made of resin is securely pressed in the outer periphery of a valve body 26 in such a manner to cover a cooling fin. Cooling of the valve part of a fuel injection valve is promoted by a cooling effect by the cooling fin.  Since an amount of fuel steam generated in the internal passage of a fuel injection valve is reduced, a fuel amount high enough to allow proper starting during the high temperature restarting of an engine is ensured and stability of an idling state is kept.

Title: Network resource managing control system
Inventor: SENSUI KIYOSHI
IPC: H04L29/08
Filed: 1984-03-14
Abstract: PURPOSE:To allow the host to manage the network without notifying physical path except adjacent path by allowing the host constituting a network system or a communication controller to manage the physical path (line) between adjacent devices. CONSTITUTION:When a network management section 1-2 in the host 1 controls a physical unit 3-1 in a terminal controller 3, the network management section 1-2 in the host 1 generates a request (session A establishment request) to establish the session A to the physical unit 2-1 in the communication controller via a channel and the physical unit 2-1 in the said communication controller 2 delivers the session A establishment request requested from the said network management section 1-2 after the session B with the physical unit 3-1 in the terminal controller 3 is established. Thus, the session A is established and the network management 1-2 controls the physical unit 3-1 in the terminal controller 3.

Title: Apparatus and method for controlling electric vehicle
Inventor: OBARA SANSHIRO
IPC: B60L9/18
Filed: 1994-03-18
Abstract: PURPOSE:To provide a torque controller which can stably control to travel by always generating an accurate torque command without influence of a shift vibration due to a mechanical resonance of an electric vehicle. CONSTITUTION:The apparatus for controlling an electric vehicle comprises a band removing filter 43 for removing a frequency of a specific band corresponding to a mechanical resonance frequency of a vehicle 1, torque command generating means 42 inputting a depressed amount of an accelerator and number Nr of revolutions of a motor 10 fetched via the filter to generate a torque command Tr based on predetermined characteristics, and motor torque control means 44 inputting number No of revolutions of the motor to be detected by an encoder 36, a motor current (i) detected by a current sensor 30 and the command Tr to generate the command Tr. Thus, speed information corresponding to a mechanical resonance frequency is so cut as not to be input to the torque command generating means by filter means. As a result, stable travel control can be conducted even at the time of an abrupt torque change.

Title: Tape speed control device of video tape recorder
Inventor: NINOMIYA ICHIROU
IPC: G11B15/18
Filed: 1980-04-11
Abstract: PURPOSE:To perform a smooth speed control with a high resolution where the fine adjustment of the tape speed is easy, by changing the carrying speed of the magnetic tape with an exponential function approximately for the extent of the change of the dial of the speed control device. CONSTITUTION:Capstan 9 is connected directly to DC motor 11, and motor 11 is controlled by the control signal from control circuit 12. This control signal is generated by the voltage from potentiometer 14 connected directly to dial 13. For the rotation angle of dial 13, the tape moving speed is changed on a basis of change curve C which changes with an exponential function as shown in the figure. As a result, the change of the tape speed is small for the change of the rotation angle of dial 13 near reproducing of the still picture, so that the smooth speed control with a high resolution where the fine adjustment of the tape speed is easy is possible.

Title: Integrated circuit device
Inventor: YOSHIDA MASAAKI
IPC: G01R31/28
Filed: 1982-03-26
Abstract: PURPOSE:To discriminate whether an abnormal state exists or not, by incorporating a logical circuit and a testing mechanism in the same chip, executing a test when an electric power source is turned on, outputting its result to the outside of the chip, and executing its own test automatically when the electric power source is turned on. CONSTITUTION:When a control part 5 receives a test signal from a test signal generator 1, it executes switching to a test mode, generates a clock and supplies it to a test pattern generator 2 and a test output compressor 4. From the pattern generator 2, a pseudo random pattern is generated and is applied to a logical circuit 3 which becomes a test object. An output of the circuit 3 is compressed by the compressor 4, and after a prescribed number of test patterns (number of clocks) is generated, the control part 5 stops generation of the clock, and reads out a data word of the output compressor 4. It is compared with an expected value data word which is read out from an expected value storage device 6, by a comparator 7, and a result regarding whether it is good or not is outputted to the outside. In this way, an external testing device is unnecessary, and the logical circuit can be tested at a low cost.

Title: Evaluation of carrier
Inventor: IWASAKI HIDEAKI
IPC: G01N27/00
Filed: 1989-03-01
Abstract: PURPOSE:To achieve an evaluation of an adhering characteristic of a carrier with respect to a photosensitive body more accurately by arranging a dielectric body stuck together with a dielectric body, a false developing roller and a carrier removing means. CONSTITUTION:An electric charge is injected into a carrier 5 by a potential difference Vb between a false developing roller 20 and a conductor 1 so that a specified amount of the carrier 5 adheres to the surface of a dielectric body 2. When the carrier adhering to the surface of the dielectric body 2 is removed, the carrier tending to escape the electric charge easily is removed by a carrier removing means 9 with the electric charge left on the surface of the dielectric body 2 while those tending to hold the electric charge easily is removed 9 with the electric charge held. Then when a potential difference Vb between the roller 20 and the conductor 1 is constant, an adhering characteristic of the carrier with respect to a photosensitive body is evaluated to be better all for the larger potential difference between the surface of the dielectric body 2 and the conductor 1 due to a residual electric charge on the surface of the dielectric body 2.

Title: Information-erasing method for semiconductor memory
Inventor: NAKAUCHI NORIO
IPC: H01L29/792
Filed: 1984-03-16
Abstract: PURPOSE:To enable information erasure without irradiation with ultraviolet rays, and to contrive the reduction in cost by plasticizing a package, by a method wherein charges are released by induction heating of a memory chip with high frequency. CONSTITUTION:When a high frequency current is passed through an induction coil 4 after insertion of a semiconductor device 3 into a housing 1, then a memory chip 7 in the semiconductor device 3 is subjected to induction heating by the high frequency electric field generating in the housing 1, and then generates heat. The electron in a floating gate obtains energy by the generated heat and moves to the substrate or a control gate, and the changes captured in the floating gate return to the original condition. Information erasure is completed thereby. At this time, since a polyimide series resin 9 is potted to the memory chip 7, the heat of the chip 7 is not directly transmitted to the package plastic, but the deformation due to the heat of the package or other influences can be prevented. It is not necessary to irradiate the memory chip 7 with ultraviolet rays like this; therefore, there is no necessity for ceramic package structure, which enables the structure of low-cost semiconductor devices.
