Title: Automatic focusing device of optical disc head
Inventor: SHIKAMA SHINSUKE
IPC: G02B7/28
Filed: 1983-09-12
Abstract: PURPOSE:To stabilize focus servo operation and to simplify initial leading-in operation at the start of the servo system by executing efficient defocusing detection symmetrical around a focused point and free from plural zero crosses. CONSTITUTION:A light flux separating element 14 is formed to separate reflected light flux 6 separated by a beam splitter 7 into reflected light flux 6', 6'' each of which is about a half light flux having a different optical path in space. A photodetector 8 consisting of two photodetecting elements 8', 8'' detecting the light flux 6', 6'' is arranged on a position far from one focused point of the two reflected light flux 6', 6'' separated by the element 14 and near from the other focused point. A signal corresponding to defocusing is obtained from the outputs of the elements 8', 8''. Consequently, efficient defocusing detecting characteristics symmetrical around the focused point free from plural zero crosses are obtained, so that the focus servo operation is stabilized and the initial leading-in can be easily attained at the start of the servo system.

Title: Protection device against robbery of car
Inventor: NAGASAWA SHIGEKICHI
IPC: B60R25/04
Filed: 1982-09-27
Abstract: PURPOSE:To ensure the protection against robbery by sending the identical signal with a preset secret code to a receiving IC for switching on an ignition circuit or a door-lock circuit. CONSTITUTION:Switches 9 and 16 are turned on by an engine key to connect a transmitting and a receiving circuit 1 and 2 to power sources 17 and 27. A secret cord is inputted by a keyboard 11, and a signal corresponding to the secret code is transmitted by a code-generating circuit 12. The signals is sent through a pulse-modulating circuit 13 and an amplifying circuit 14, and converted into infrared rays by a light-emitting diode 15 for transmission. This light signal is received by a light-receiving diode 21 of the receiving circuit 2 for converting into an electric signal. The signal is sent through an amplifying circuit 22 and a detection wave-form shaping circuit 23, and compared with the preset secret code in a code-reading circuit 24. When the signal is found identical with the secret cord, the circuit 24 sends a signal to switch on a power amplifier circuit 25, and operates a control circuit 26. Consequently, an ignition circuit 4 is brought into operation. The same process is performed for door locking.

Abstract: PURPOSE: To combust heavy oil in an efficient and economical manner, by providing a heat exchanger for heating fuel by the heat of combustion gas in an exhaust- gas passage of an apparatus for combusting heavy oil such as asphalt and tar by injecting the same into a burner.  
     CONSTITUTION: A heat exchanger 2 is provided in an exhaust-gas passage of a boiler 1, so that combustion gas discharged from the boiler 1 is carried into a smokestack 3 after passing through the heat exchanger 2. On the other hand, fuel consisting of a heavy oil such as asphalt and tar is heated by combustion gas in the heat exchanger 2 for lowering its viscosity after it is pressurized by a pump 4, and then a proper amount of fuel required by the boiler 1 is supplied to a burner 6 via a fuel control valve 5 which controls the flow rate of fuel. With such an economical arrangement, it is enabled to combust the heavy oil efficiently by injecting the same into the burner 6. Further, the above arrangement is advantageous in saving energy since the sensible heat of combustion gas is recovered by the heat exchanger.

On the other hand, the hot water cooled in a dry type cooling section 2 is fed into a wet type cooling section 3, cooled further by exchanging heat with the air introduced to the section 3 by directly contacting with the surface of filling layer, and is reserved in a water tank 4. The wet air W produced in the tank 4 is fed into a mixing chamber 5 through horizontal dampers 7, mixed with the dry air D, and is exhausted to an exhaust port 10. At this time, a wet and a dry air W and D flow into a mixing chamber in the state of layers, crossing alternately, by the intermediary of vertical dampers 9 and horizontal dampers 7, so that mixing of both air is facilitated, and the humidity of exhaust air is uniformly lowered, as a result, white smoke is prevented from coming out of a cooling tower.
