Title: Led lamp and manufacture of the same
Inventor: ABE OSAMU
IPC: H01L33/62
Filed: 1987-02-19
Abstract: PURPOSE:To realize a solid structure and improve an effective light taking out factor by a method wherein jointing parts of lead terminal planes and external lead wires are fixed by the external circumferential wall of a reflective saucer which has a structure with a widely continuous reflective internal wall surface. CONSTITUTION:Lead terminal planes outside lead terminal planes 16a and 17a are continuously jointed to external lead wires 16 and 17 respectively. As those jointing parts are fixed by the external circumferential wall 11b of a reflective saucer 11, the lead terminal planes 16a and 17a are held in a stable state. Therefore, if light emitting diode chips D1-D4 and necessary metal fine wires are bonded on the lead terminal planes 16a and 17a and transparent resin is cast into a light guide part 20, defective parts caused by the transfer of light emitting diode lamps or the like at the time of LED lamp production are not created. Further, as a large reflective saucer 11 is available in the LED lamp and a light is effectively reflected by the internal bottom surface 11d and the internal circumferential wall surface 11c and taken out from the front side of the lamp, the effective light taking out factor can be significantly improved.

Abstract: PURPOSE: To maintain the flow inertia of a suction air evern after the end of suction stroke and improve the charging efficiency of a fuel-air mixture by a construction wherein an airtight chamber is formed in a cylinder head and the chamber is communicated with a suction passage at the downstream of a throttle valve.  
     CONSTITUTION: The airtight chamber R 3  is formed at the top of the cylinder head 12 and the airtight chamber R 3  is communicated airtightly with the suction passage P 1  at the point between the throttle valve 15 and a reed valve 16. During the operation, when a suction valve V is closed to end the suction stroke, the fuel-air mixture made by a carburetor 10b tends to continue flowing by its inertia and said flow inertia is maintained due to the increase in suction passage volume at the downstream of the throttle valve 15 with the formation of the airtight chamber R 3  as described above. Consequently after that, when the suction valve V is opened again, the fuel-air mixture having the flow inertia is swiftly sucked in a crank chamber R 2 . And as well the fuel-air mixture in the airtight chamber R 3  is sucked in the crank chamber R 2  in a high speed stream through a fitting pipe 17b. As a result, the fuel-air mixture is charged effectively.

Filed: 1985-02-25
Abstract: PURPOSE:To simplify the circuit constitution and to improve the temperature characteristics by monitoring the power supply voltage supplied to a digital device and transmitting a reset signal through a resetting circuit when said power supply voltage is reduced less than a reference level. CONSTITUTION:A constant voltage power supply device 4 is controlled so that a control transistor TRQ3 is driven by a TRQ4 and the power supply voltage E0 is kept constant based on the divided voltage EV of the power supply voltage E0 and the reference voltage ES of a Zener diode ZD1.

There the IZ is set so that the current IX flowing through a resistance R1 is larger than the emitter current IY of a TRQ5. Thus no current IZ flows if the voltage E0 is reduced less than the voltage ES of the diode ZD1. Then the TRQ1 and TRQ2 are turned off and on with the reset voltage ER set at 0 respectively.

Title: Suspended load oscillation angle detector
Inventor: SHIBATA TADAHIDE
IPC: B66C13/22
Filed: 1992-02-24
Abstract: PURPOSE:To always detect the correct oscillation angle of a suspended load regardless of the acceleration-deceleration of a truck. CONSTITUTION:A first oscillation angle sensor 7 is fitted to the end of a hoisting rope so as to detect the oscillation angle of a suspended load. This first oscillation angle sensor 7 is influenced by the acceleration-deceleration of a truck 4. The first oscillation angle sensor 7 therefore outputs an original oscillation angle detection signal indicating the oscillation angle of the suspended load including an error. In order to nullify this error, a second oscillation angle sensor 14 is fitted onto the truck 4. This second oscillation angle sensor 14 detects the accelerated-decelerated state of the truck 4 and outputs an accelerated-decelerated state detection signal indicating the detected result. A subtracter 15 then subtracts the accelerated-decelerated state detection signal from the original oscillation angle detection signal so as to output a true oscillation angle detection signal indicating the true oscillation angle of the suspended load W got rid of the above-mentioned error.
