Inventor: ISHII TAKAO
IPC: E21B41/00
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To form a gallium nitride semiconductor epitaxial thin film free of a domain structure and reduced in transition on a lithium galate single crystal substrate by growing a single crystal with a seed crystal having a crystal axis at an angle of 30 deg. from the b axis direction at the time of pulling up and producing the lithium gallate single crystal by the Czochralski process and using the main surface as a c face. SOLUTION: A lithium gallate single crystal is pulled up at a deflection angle of 30 deg. from the b axis (010) direction and grown by the Czochralski process. A c face substrate is cut out from the obtained single crystal. The substrat is annealed, polished and etched to form a lithium gallate substrate with the surface as a single-domain c face (+c and -c regions are not coexistent). The substrate is irradiated with the nitrogen radical and gallium flux from a radical beam source, and a GaN thin film having an excellent characteristic as the light emitting element in a shot-wavelength region by molecular beam epitaxy.

Abstract: PURPOSE:To realize the asynchronous action of two-way code conversion, by providing the 1st PLL circuit plus its subordinate 2nd PLL circuit. CONSTITUTION:The 2nd PLL circuit 25 receives clocks CLK1 and CLK2 of different phases which have a comparatively high frequency compared with the clock that is produced from a voltage control type oscillator within the 1st PLL circuit 24. Then one of these two clocks is selected through a clock selecting circuit 31 to be used as a clock CLK3. This clock CLK3 is divided by a frequency divider circuit 32 to produce a clock corresponding to a receiving synchronous signal 27, and the phase comparison is carried out through a phase comparator 30. The clock is consecutively used if the state of phase is satisfactory and then replaced with another clock if the state of phase becomes unsatisfactory.

Title: Stereoscopic image scanner
Inventor: HASEGAWA WATARU
IPC: H04N1/04
Filed: 1990-01-25
Abstract: PURPOSE:To eliminate the adverse effect on picture forming due to fluctuation of illuminance caused by power ripple without detecting a luminous quantity of a light source by detecting the fluctuation period of the illuminance when the illuminance on an object is fluctuated due to power ripple and controlling the read operation of an object by a line sensor in response to the result. CONSTITUTION:An illumination state detection circuit 6 extracts only a fluctuation due to power ripple from an output of a photodetector sensor to be received and amplifies the extracted output. An illuminance period pulse generating circuit 7 generates an illuminance period pulse having a frequency synchronously with the fluctuation of the illuminance state due to power ripple or having its relevant frequency. A drive pulse generating circuit 8 generates various pulses required to drive a line sensor in a timing synchronously with the output fed from the illuminance period pulse generating circuit 7. When an object 1 is read by the line sensor 3 in the same timing with respect to the fluctuation phase of the illuminance, almost the same lightness, in other words, almost the same signal level is ensured.

Title: Hydraulic cylinder
Inventor: MATSUDA MINORU
IPC: F16J10/00
Filed: 1982-02-04
Abstract: PURPOSE:To prevent operating oil from leaking outward from the forward end surface of a cylinder head by mounting a groove portion for an oil reservoir on the forward inner peripheral surface of the cylinder head. CONSTITUTION:A very small amount of oil, which passes through a gap between a wiper ring 9 and a piston rod 5 to come oozing outside of the siper ring 9, flows in the interior of a groove portion 12 through the inlet end portion 14 thereof and collects in an oil reservoir portion 13 little by little. The oil collected in the oil reservoir portion 13 is naturally evaporated from a space portion 16 formed between the inside peripheral edge of the front wall portion 15 of a cylinder head 7 and the outer peripheral surface of the piston rod 5, under the working condition of a high temperature during the daytime. Thus, oil is prevented from directly leaking outward from the cylinder head 7, unlike a conventional case.

Title: Color video camera
Inventor: NODA MASARU
IPC: H04N9/64
Filed: 1986-01-29
Abstract: PURPOSE:To simplify a circuit constitution, to reduce cost, and to prevent an interference in a chrominance signal due to noises included in a luminance signal by inserting a carrier wave frequency trap for carrier chrominance signals in a luminance signal channel before the multiplexing of carrier chrominance signals, and controlling it to act when the illuminance of an object is lower than a prescribed value. CONSTITUTION:When the rays of light are made incident on a photodiode 71, an electric current is conducted to the direction of arrow, and the output of an amplifier 72 comes to a high potential. As the illuminance goes lower, the said potential goes lower. When the said lowering comes below the prescribed value, a transistor 73 turns ON to turn a switch transistor 61 ON, and the carrier wave trap 50 starts to operate. Consequently, the color carrier wave (f) frequency of the brightness signal and the frequency components in the vicinity of the said frequency among the noise components included in the luminance signal, are attenuated. And thus a noise interference in the carrier chrominance signal at the stage of multiplexing the signal is prevented from being occurred. When the illuminance is high, the traps 50 is in non- operating, to cause no attenuation of the higher components of the luminance signal. As a result, the high resolution can be maintained.

Filed: 1987-01-28
Abstract: PURPOSE:To judge whether a device has a fault or not when erroneous operation occurs readily and to acknowledge the operation without hardly increasing power consumption, by emitting visible light in synchronization with the transmission by infrared rays. CONSTITUTION:In a light emitting part, an infrared-ray emitting diode D1, which emits infrared rays, and a visible-light emitting diode D2, which emits visible light, are provided. A transistor Q is connected to the light emitting diodes D1 and D2 in series. The transistor Q is turned ON and OFF by a driving part 3. Thus the flash signals of the light beams from the light emitting diodes D1 and D2 are transmitted. The infrared-ray emitting diode D1 is used for a transducer, which transduces the electric signal of the light emitting signal into the optical signal. The visible-light emitting diode D2 for emitting the light in synchronization with the infrared rays is provided. The visible light is emitted at the same time as the signal transmission with the infrared rays. Therefore, whether the device has a fault or not can be readily judged when the light is emitted by erroneous operation. Since the light emitting diode D2 whose power consumption is less is used, consumption of a battery is less.
