Title: Motor controller
Inventor: NISHIDA YOSHIHARU
IPC: H02P27/04
Filed: 1993-06-11
Abstract: PURPOSE:To realize a high sampling period while ensuring the control accuracy by conducting the operation using two operating means thereby reducing the amount of calculation as a whole. CONSTITUTION:A current component command circuit 6' commands the current component for the main flux of driving power being to a motor 3 from an AC power supply 1 through a power converter 2. The current component is detected by a current component detecting circuit 5' through a current detector 4. A first operating circuit 7' operates a first correction value based on the outputs from the circuits 5' and 6'. A second operating circuit 9' operates a second correction value based on the each phase current component of driving power detected through the current detector 4. Each phase current command circuit 8' commands each phase voltage component of the power converter 2 based on the first and second correction values and the power converter 2 controls driving power of the motor 3 based on the command. This constitution realizes a high sampling period while ensuring the control accuracy.

Title: Printer and method for detecting paper jam
Inventor: TOKUDA AKIHIKO
IPC: B65H7/06
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To provide a printer and a paper jam detecting method in which detection of paper jam occurring in a stacking means is improved and development of the stacking means and the printer body is simplified. SOLUTION: Paper jam occurring in a stacking means 6 is detected at a jam detecting section 8 disposed in the stacking means 6 and when paper jam is detected at the jam detecting section 8, a paper feed roller in a paper feed section 9 is turned reversely and a jam detecting section 5 of the body detects paper jam. Consequently, a printer controller 3 can detect occurrence of paper jam in the printer. Only a signal indicative of start/end of data printing 15 communicated between the stacking means 6 and the body and the printer controller 3 in the body 2 is not required to monitor paper jam occurring in the stacking means 6. This arrangement facilitate development of the stacking means 6 and the printer controller 3.

Title: Locking mechanism for electrical connector
Inventor: SUZUKI AKIO
IPC: H01R13/639
Filed: 1995-05-17
Abstract: PURPOSE: To prevent the occurrence of a breakage resulting from the disengagement of connectors from each other, due to the action of an excessive external force by forming the rear surface of a locking projection and the locked surface of a locking recess at a relative angle so as to have a gap expanded like a wedge from a guide plane toward the deeper side of the recess. CONSTITUTION: When an external force acts in an upward direction, the projection 17 of a locking arm 15 is released from the groove 38 of a carrier section via a slope 38A formed thereon. On the contrary, a slope may be formed on the projection 17 and not on the groove 38. When the projection 17 is detached from the groove 38, the end of the arm 15 is elastically warped internally and a locking projection 16 is also detached from a locking recess 39, thereby allowing a connector to be easily detached. According to this construction, a locking mechanism, a contactor or the like becomes free from a breakage and a damage.

Abstract: PURPOSE:To launch and guide a missile accurately from a ship by detecting an angular deviation of a coordinate system on a ship from a terrestrial coordinate system obtained by an inertial device, and transforming a coordinate system for fire and guidance control to the terrestrial coordinate system on the basis of the results of detection. CONSTITUTION:An inertial device 11 forms a terrestrial coordinate system THETA, PHI based on the magnetic north and the horizontal direction, then conforms an FCS coordinate system of a missile fire control system 12 to the terrestrial coordinate system in an initial condition, and sets detection angles theta, phi of angle sensors 122, 123 to zero.

The angular deviations are subtracted from the terrestrial coordinate system by the inertial device 11 to correct the FCS coordinate system, thereby representing azimuth and elevation angle control signals delta, epsilon for controlling the launching direction of a missile launcher 13 in the terrestrial coordinate system. Angular data delta', epsilon' on a target T of fire is detected by a radar device 141 of a fire target guidance device 14, and a guidance coordinate system of a fire target control device 143 is transformed to the terrestrial coordinate system according to the deviation data. It is thereby possible to launch and guide a missile accurately from a ship, regardless of variations in the position and angle of the ship.

Title: Surge protection circuit
Inventor: AISAKA TOSHIFUMI
IPC: H02H9/04
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To provide the surge protection circuit of a control device for an electric motor where a power supply will be short-circuited. SOLUTION: A capacitor 5 is connected between the lines of the power supply side of a converter part, and a surge absorption circuit 6, where a surge absorber that is mainly made of zinc oxide and a surge absorber of a discharge tube type is connected in series between at least one phase of a power supply 1 and the ground. When a surge is generated between one phase of the power supply and the ground, the surge absorber of discharge tube type is disconnected and plays a role of a fuse for preventing the power supply of a control device for an electric motor from being short-circuited, even if the surge absorber that is mainly made of zinc oxide should be broken in a short mode since the surge absorption circuit 6 is inserted between one phase of the power supply of the surge absorption circuit 6 and the ground.  Also, when the surge is generated between the wires of the power supply, the capacitor 5 between the wires is open-circuited, thus preventing the power supply of the control device for the electric motor from being short-circuited.

Title: Vibration absorbing damper
Inventor: KAWAHARA TETSUO
IPC: F16F15/03
Filed: 1987-06-05
Abstract: PURPOSE:To achieve the efficient absorption of vibration and the prevention of the occurrence of spillover, in the vibration absorbing damper of a large-scale structure for space use, by providing, in its interior, a vibration absorbing circuit consisting of a coil, a capacitor, and a resistance, and a magnet capable of relatively moving inside the coil. CONSTITUTION:In the inside of a vibration absorbing damper 6, a coil 3 and a magnet 2 which is capable of moving in the axial direction inside the colt 3 are provided. And the coil 3 is connected electrically in series with a capacitor 4 and a resistance 5, so as to form a vibration absorbing circuit as a whole. When the vibration of a flexible structure 10 is transmitted to the case 7 of a vibration absorbing damper 6, the magnet 2 oscillates inside the coil 3 in the axial direction in response to the vibration of the case 7. As a result, an induced electromotive force is generated in the coil 3, and a current flows in the vibration absorbing circuit, so that double heat is generated by the resistance 5. Thus, since the kinetic energy due vibration is converted into heat energy, an efficient absorption can be achieved and the occurrence of spillover can be prevented.
