Title: Rotary head type video signal reproducing device
Inventor: TAKAYAMA NOBUTOSHI
IPC: G11B5/588
Filed: 1984-03-21
Abstract: PURPOSE:To execute good tracking at an optional medium transfer speed by inputting a count value of a pulse obtained in relation to a recording medium transfer operation, and changing a rotary head by a count value of a pulse obtained in relation to a rotation of the rotary head. CONSTITUTION:A recording track formed by a prescribed track pitch on a magnetic tape 1 is traced by rotary heads 2a, 2B changed in the direction crossing the rotary surface by a converting element controlling circuit 55, and a video signal is reproduced. The tape 1 is transferred by a capstan 10, and a frequency signal generator 12 generates a capstan signal FG. A rotary phase detector 6 detects a rotary phase of the heads 2A, 2B, and outputs a signal HSW. A pattern signal generating circuit 56 inputs a signal related to the signal FG and HSW and executes an up-down count by a counter, and generates a signal for driving converting elements 3A, 3B. In this way, good tracking can be executed at an optional tape transfer speed.

Title: Fuel injection valve
Inventor: EBUARUTO TSUIIGURAA
IPC: F02M61/16
Filed: 1989-03-08
Abstract: PURPOSE: To reduce toxic components in exhaust gas by forming a center opening downstream of a valve seat face, at least two tangential conduits extending radially outward from the central opening and each discharging tangentially into a separate swirl chamber, and a metering opening from the center of each swirl chamber to outside. CONSTITUTION: At least two tangential conduits 28 extend radially outward from a central opening 13, 24, 25 of a valve seat 12. Each of the tangential conduits discharges tangentially into a separate swirl chamber 27 including a fuel metering opening 29 communicating the center of the swirl chamber 27 to outside 30. The rotating fuel in each swirl chamber 27 forms a potential vortex with a central vortex core above each metering opening 29. This imposes a tangential force on the fuel emerging from each metering opening 29 at a bottom face 30, which in turn leads to a uniform distribution of fuel in each cone-shaped fuel stream. As a consequence, a regulated fuel-air mixture can bring about a reduction in fuel consumption and a reduction in the proportion of toxic components in the engine exhaust.

Title: Road interchange lighting device
IPC: H02H1/00
Filed: 1992-03-13
Abstract: PURPOSE:To monitor lighting state within a road interchange properly by combining an auxiliary relay which displays an interlocking state of a lighting lamp and an all ON dimmer lighting signal or remaining dimmer lighting signal from a series circuit of an operation signal of an automatic dimmer device and a lighting lamp circuit contactor contact. CONSTITUTION:An auxiliary relay 15 receives a signal when general lamp contactors 21-25 and remaining lamps 31-33 are ON and a dimmer contactor 5 is OFF in the case of all ON, a contact an outputs an all ON display to a center and at the same time a display mode agreement relay 19 is also operated. Similarly, when a proper mode is selected in the case of all ON dimmer, remaining dimmer, and OFF, combination of lighting contactors is replaced by the auxiliary relay and an interlocking display signal is output to the center. On the other hand, when a proper mode is not selected, the auxiliary relays 15-18 are not operated so that an external contact 19b without display mode is output, thus indicating the state without mode, thus enabling interlocking display at the center side to grasp illumination lighting state of interchange more clearly as compared before.

Title: Injection timing controlling apparatus for distributor type fuel injection pump
Inventor: KOBAYASHI MASAYOSHI
IPC: F02D1/18
Filed: 1979-05-02
Abstract: PURPOSE: To advance ignition timing in a reliable manner, by urging the second piston having a larger pressure-acted area onto the first piston by means of the second spring having a large spring force, and transmitting a hydraulic pressure related to the engine speed to these two pistons.  
     CONSTITUTION: At the time of starting engine, hydraulic pressure in a suction space is zero, so that hydraulic pressure transmitted to piston 43 via passage 39 is also zero. Therefore, piston 43 is shifted to the left by spring 45 and closes passages 41 and 42, so that hydraulic pressure in oil chamber 12 formed between the first piston 3 and the second piston 4 is zero. Resultantly, the second piston 4 is shifted to the left by spring 8 and the first piston 3 is urged to the left by projection 4a. This causes advancing of ignition timing. When hydraulic pressure transmitted via passage 39 and acted between cylinder port 38 and piston 43 becomes higher than the spring force of spring 45 as the engine speed is raised, piston 43 is shifted to the right and passages 41, 42 are communicated with each other, so that ignition timing becomes normal. By thus advancing ignition timing at the time of starting engine in reliable manner, engine stop can be prevented positively.

Filed: 1993-03-16
Abstract: PURPOSE:To obtain transformer of high insulation performance by using a spacer formed by thinning a member vertical to opposite surfaces of a winding or by using a spacer of plastic foam material as a spacer used for an insulation structure material between windings. CONSTITUTION:A spacer 7 is placed at regular intervals all over an entire circumference between an outside insulation tube 3 of a low tension winding 1 and an inside insulation tube 4 of a high tension winding 2 and receives radius force working between the high and low tension windings and holds a length of a clearance between the high and low tension windings fixed. The spacer 7 is constituted by applying a sheet-like member 71 vertical to opposite surfaces of a winding to a sheet-like member 72 parallel to opposite surfaces of a winding. A thickness of the sheet-like member 71 vertical to opposite surfaces of a winding is made at most 3% of a gap length between windings. Since field concentration to a fine gap generated in a part wherein a spacer is placed is thereby reduced, insulation strength between windings can be improved.
