Title: Timed trouble investigator
Inventor: TAGUCHI ISAO
IPC: H02H7/26
Filed: 1977-12-06
Abstract: PURPOSE: To quickly restore a line to a proper state if instantaneous cut-off occurs in the line at a position "direct transmission", by supplying voltage outputs to a control circuit through rectifiers and using the higher voltage output as a control power source of the control circuit.  
     CONSTITUTION: The timed trouble investigator is set insuch a handle position (direct transmission) as to open switches SW4, SW5 and close other switches SW1, SW2, SW3 so that a timer circuit 18 is disconnected and an immediate sectioning switch 14 is turned on by an input selector circuit only. When there is a voltage on the side of a power source, the immcdiate sectioning switch 14 is turned on by a circuit consisting of the switch SW1, a diode D2 and the switch SW2. When there is a voltage on the side of a load, the immediate sectioning switch 14 is turned on by a circuit consisting of the switch SW3, a diode D3 and the switch SW2. A relay X 1 is held for 2 seconds and the sectioning switch 14 is immediately restored and reclosed according to the instantaneous cut-off and restoration of the power even if the instantaneous cut-off takes place on the side of either the power source or the load after the switch 14 is turned on. Thus, the time of power failure in the high voltage distribution line is prevented from being lengthened due to the instantaneous power cut-off even if the timed trouble investigator 17a is in the handle position.

IPC: F02D41/36
Filed: 1983-08-13
Abstract: PURPOSE:To precisely detect the vacuum of intake-air just after the change-over between the all cylinder number operation and the reduced cylinder number operation, by newly initiating the computation of the averaged value of intake-air vacuum values which are obtained by sampling the vacuum of the intake-air after the change-over. CONSTITUTION:During engine-operation, a control unit 28 which receives the outputs signals from sensors 3, 29, 30 for detecting the opening degree of the throttle valve, the temperature of cooling water, the vacuum of intake-air pressure, respectively, and an engine rotational speed signal from the ignition coil 31, judges wherther the engine runs in the reduced cylinder number operating range or not. When it is so judged, the supply of fuel to a part of the cylinders is cut off to change the engine into its reduced cylinder number operating condition. Simultaneously, by controlling an averaged value computing control means for computing the average of sampled vacuum values of intake-air, the computation of the average is newly initiated after the change-over between the all cylinder number operation and the reduced cylinder number operation with the use of vacuum values of intake-air which are sampled after the change-over. Then, the thus obtained averaged intake-air vacuum is used to control the injection amount of fuel.

Title: Data transmitting system
Inventor: YAMANE SHINGO
IPC: H04L29/08
Filed: 1981-09-16
Abstract: PURPOSE:To avoid an error of the data transmission, by transmitting a specific pattern which is turned into an error of detection through a serial-parallel converter and avoiding the reception of this pattern at the receiver side in case a hand shaking procedure including the request of each transmission of data and the exchange of reply signals is not established. CONSTITUTION:A data request signal RQ and a data signal DT are fed to a parallel-serial converter 2 from a data processor 1. Then a reply signal RS is sent back from the converter 2 which has received the signal RQ. The converter 2 contains a memory 2a which stores temporarily the signal DT, a parallel-serial converter 6 which gives the parallel-serial conversion to the signal DT read out of the memory 2a, and a detecting circuit 7 which detects a fault of a hand shaking procedure. When the circuit 7 detects an error of the hand shaking procedure, an idle pattern is produced through an AND gate 8 to cause an error of detection to the transmission code. Then the transmission code containing the idle pattern is fed to a serial-parallel converter 3 from the circuit 6. Thus an error is prevented for the data which are fed to output devices 4 and 5.

Abstract: PROBLEM TO BE SOLVED: To ensure optimal conditions with high efficiency for any speed by providing extra magnetic detectors corresponding to respective control speed. SOLUTION: A magnetic detector for high speed 4-1 comprising a Hall element is secured at a position shifted by an angle θM2 (about 14 deg.) reversely to the rotational direction of a rotor from the slit between two adjacent poles and a magnetic detector for low speed 4-2 is secured at a position shifted by an angle θM3 (about 30 deg.). A signal inputted to a speed command signal input terminal G is delivered to a speed (duty factor) control circuit 6 and a magnetic detector switching circuit 8 and the magnetic detectors 4-1, 4-2 are switched selectively. In case of a high drive speed command signal, for example, the magnetic detector switching circuit 8 selects the magnetic detector 4-1 (for high speed) and supplies a large conduction current corresponding to high speed drive at the conduction timing of the magnetic detector 4-1.  In case of a low drive speed command signal, the magnetic detector 4-2 (for low speed) is selected and a small conduction current corresponding to low speed drive is supplied at the conduction timing of the magnetic detector 4-2.

Title: Branched artificial blood vessel
Inventor: JO YASUSHI
IPC: A61F2/06
Filed: 1993-06-18
Abstract: PURPOSE:To prevent the leakage of blood easy to generate in the branched part of a branched artificial blood vessel by coating the sutured part of the artificial blood vessel formed by suturing with a polymeric elastomer. CONSTITUTION:In order to perfectly prevent the leakage of blood from the pinhole due to suturing formed in the sutured part of a branched artificial blood vessel or from the place where the adhesion of an artificial blood vessel conductor is insufficient of the sutured part, the sutured part is coated with a polymeric material having elasticity. Coating is applied to the entire peripheries of sutured side tubes B, D, E, F along the circular suturing lines thereof. Coating width may be set to width sufficient to contain a sutured circumferential part but is usually set to width conaining the puncturing part of a needle at the time of suturing. As the polymeric material, a polyurethane or polysiloxane is used. Since the polymeric material having elasticity penetrates into the interstices between fibers to form a film, the leadage of blood at the time of operation can be perfectly prevented and the leakage trouble of blood due to the opening at the roots of the side tubes can also be prevented.
