Title: Semiconductor laser
Inventor: UKO KATSUYUKI
IPC: H01S5/12
Filed: 1987-05-29
Abstract: PURPOSE:To make an oscillation wavelength variable by mutually adjusting a refractive index of a region by a method wherein a light-emitting region and a waveguide region are integrated and a filter region equipped with a diffraction grating having a filtering function is installed in one part of the waveguide region or one part extended from the region. CONSTITUTION:A laser resonator is composed of a light-emitting region A, a non-light- emitting region (a waveguide region B and a filter region C) and a pair of reflection end faces 12, 12'; there are a number of resonance modes in accordance with a resonator length L which is an effective device length experienced when the light is propagated essentially. A wavelength width depends on a coupling coefficient and a length of a diffraction grating, on a phase shift amount, on a phase shift position and the like; it is possible to pass only one resonance wavelength lambda0 selectively. If a cycle of the diffraction grating 3 is selected, only a wavelength of a resonance wavelength lambda0 is confined strongly inside a resonator; as a result, it is possible to obtain an oscillation at a single wavelength of the resonance wavelength lambda0. By using a semiconductor laser it is possible to satisfy a requirement to operate at a single wavelength and to lengthen the resonator length; it is possible to realize a narrow oscillation line width by the long resonator length.

Filed: 1987-06-01
Abstract: PURPOSE:To obtain a part of this design excellent in hermetical property by a method wherein a nickel plating or a copper oxide film is formed on a cooling plate formed of pure copper, which is irradiated with radiation of high energy for welding the end of bellows core of beryllium-copper. CONSTITUTION:A cooling part, with a bellows in which coolant is circulated, is composed of a cooling plate 3 contacted with a large scale integrated circuit 6 and a bellows core 2 connected with the cooling plate 3. In this processing, a nickel plating or a copper oxide film is formed onto the cooling plate 3 of pure copper, then the end of the bellows core 2 is welded through irradiation of the high energy radiation. As a nickel plating or a copper oxide film is formed on the surface of the copper plate and this plating or film is small in thermal conductivity and reflectivity, the end of a bellows core can be welded through irradiation of the high energy radiation. By these processes, high airtightness can be obtained.

Inventor: SAKASHITA SEIJI
IPC: H03D3/02
Filed: 1987-05-29
Abstract: PURPOSE:To stabilize the phase synchronization and to improve a threshold level by using the output signal of a phase comparator of a demodulator as a gain control signal so that a phase synchronizing state is detected and at the same time the attenuation due to a tracking BPF is corrected to secure the constant intensity of an input signal applied to the phase comparator. CONSTITUTION:The oscillation signal of an oscillator 7 is partly supplied to a phase comparator 17 via a pi/2 phase shifter 15 and an input FM signal has the same phase as the oscillation signal for execution of the synchronizing wave detection while the phase synchronization is secured with a loop formed by a phase comparator 4. In other words, the output of the comparator 17 is partly supplied to a gain control driving circuit 9 so that the DC voltage or the DC current is obtained in accordance with the intensity of the input signal of the comparator 17 and supplied to a gain controller 3. As a result, the input signals are supplied to phase comparators 4, 17 at a fixed level of electric power to ensure a constant level of the loop gain. Thus the phase synchronization is stabilized and the gain control is accurate so that the intensity of the FN signals supplied to the phase comparators are kept at a fixed level. Then the threshold level is improved.

Filed: 1994-06-17
Abstract: PURPOSE:To apply operating power voltage higher than the level of the inter- terminal breakdown strength by sending the output of a logic circuit to the gate of a transfer FET via a voltage conversion circuit and giving the bias voltage to the source of the FET respectively. CONSTITUTION:The operating power voltage VDD and the analog switch operating power voltage VCC are made 3V and 5V respectively in a logic circuit 38 consisting of a micro-CMOS where the inter-terminal breakdown strength is limited at a low level. When a control signal is inputted to a terminal S to secure conduction of an analog switch, the output of an inverter consisting of CMOS 34 and 35 is set to the potential of the VDD. A voltage conversion circuit 20 converts the VDD potential into the potential of the VDD and sends it to the gate of an NMOS 11 consisting a transfer gate. A bias circuit 29 applies the bias voltage decided in proportion to the VCC to the source of the NMOS 11. When the ratio is properly set between the resistors 25 and 26, both gate-source and drain-gate voltages of the NMOS 11 can be kept at a level lower than the inter-terminal breakdown strength of the CMOS.

Title: Output supplementing method by utilizing wind force in automobile or the like
Inventor: KOGA NORIMICHI
IPC: F03D9/00
Filed: 1979-10-18
Abstract: PURPOSE: To increase rotating force of an engine by utilizing wind force enhanced as an automobile travels to rotate a wind mill.  
     CONSTITUTION: When an automobile and other vehicles 1 start to travel by starting an engine 3, air resistance applied to the vehicle 1 also increases to start the rotation of a wind mill 2. When the rotational frequency of the wind mill 2 rises as the vehicle 1 travels with higher speed and the rotational frequency of a pully 7 bult in a clutch and rotated by the windmill 2 exceeds that of a crankshaft 6, the clutch connects the pully 7 to the crankshaft 6 so that the turning force of the windmill 2 supplements that of the crankshaft 6. Thus the output of the crankshaft 6 increases by the output of the wind mill 2 rotating with high speed so that a generator and car cooler can be interlocked with the engine without overload, and fuel consumption can be saved since the output of the engine can be saved by the output of the wind mill 2.

Title: Two-line ac contactless switch
Inventor: NODERA HISATOSHI
IPC: H03K17/725
Filed: 1977-11-11
Abstract: PURPOSE:To reduce the leaking current, by keeping current from flowing through a trigger circuit for a silicon controlled rectifier connected to both the terminals of a rectifier circuit when a series circuit consisting of a power supply circuit and the silicon controlled rectifier through a sensor circuit. CONSTITUTION:A transistor 24 is turned on or off by the action of the sensor circuit 1 such as a proximity switch to control the silicon controlled rectifier 22. A transistor 36 is coupled between a resistor 25 and the gate of the rectifier 22 and is turned on or off by the NC output of the sensor circuit 1. When the rectifier 22 is open, the transistor 36 is open and no current flows through the trigger circuit. Thus, the total leaking current is reduced. At the same time, the transistor 24 is closed and its gate and cathode are short-circuited. Therefore, the wrong operation of the silicon controlled rectifier 22 due to noises is prevented.
