IPC: G11B7/09
Filed: 1989-03-30
Abstract: PURPOSE:To facilitate the installation and the adjustment of the under-mentioned light receiving elements by letting reflected light from an information recording medium pass through a double-sided grating element, and leading transmitted or diffracted light to the approximately same direction, and receiving it by separate trisected light receiving elements. CONSTITUTION:The reflected light from an optical disk is converged 26, and is made incident to an approximately straight line-shaped diffraction grating 31 on the surface of the double-sided grating element 27, and is separated into the transmitted light T and the diffracted light K. The separated trisected light receiving elements 29, 30 are irradiated with these lights T, K after being transmitted and diffracted through/by the approximately straight line-shaped diffraction grating 32 on a rear surface. At that item, since the optical path of the light K becomes longer than that of the light T, the focusing point P of the light P and the focusing point Q of the light T are positioned at this side and in the rear of a light receiving surface respectively. A focus can be controlled by using these elements 29, 30. Namely, since astigmatism is caused by arranging the element 27 at a Bragg's angle thetab, and the focusing point at the time of a focus error signal FE=0 becomes larger than that at the time of no astigmatism, the installation and the adjustment of the elements 29, 30 can be facilitated to be executed.

Title: Oil pressure control circuit for driving inertial body
Inventor: YOSHIDA KUNIHIKO
IPC: B60T7/12
Filed: 1981-05-27
Abstract: PURPOSE:To prevent the heating and wear of a mechanical brake and the decrease in its braking force, by synchronizing the braking action of the mechanical brake with the stoppage of rotation of a hydraulic motor. CONSTITUTION:When a direction control valve 5 is shifted to its neutral position during the rotation of a hydraulic motor 2, the pressure of the chamber of a pilot-type direction control valve 20 is made high because of the resistance of an orifice 21 to pressurized oil flowing through it, so that the valve 20 is shifted to its left-hand position. As a result, the inlet port of a valve 14 communicates with a cylinder 16 and pressurized oil the hydraulic motor 2 acting to the valve is conducted into the cylinder so that a brake 15 remains out of operation while the hydraulic motor continues its rotation under inertial force. When the rotation of the hydraulic motor 2 has stopped, the rate of flow of the pressurized oil through the orifice 21 becomes zero and the valve 20 is shifted to its neutral positon so that the brake 15 operates.

Title: Carrier wave reproducing device
Inventor: SUGIYAMA FUMIO
IPC: H04L27/227
Filed: 1978-06-30
Abstract: PURPOSE:To always ensure the steady reproduction of the carrier wave by preventing the shift of the stability poing of the loop in the period of a small carrier-noise ratio C/N, and thus to reduce the bit error rate of the demodulation data in the coherent detection. CONSTITUTION:With application of digital phase modulation signal PSK wave (a), the carrier wave is reproduced through voltage control type oscillator VCO15. And demodulation data (b) is obtained from modulator MOD16. The demodulation data is supplied to clock reproduction circuit 18 to reproduce clock (c) and then supplies the clock to sampling control circuit 14 to produce the sampling control signal like (d). The sampling action of sampling hold circuit SH13 is blocked while the control signal is kept at the L level, i.e., the C/N of the PSK wave is small. Then the output of LPF12 obtained in the period of a large C/N is held and then applied to VCO15. As a result, the noise gives no effect to the control voltage of VCO15 even for noise (e) of the PSK wave in the period of a samll C/N.

Abstract: PROBLEM TO BE SOLVED: To efficiently and photoelectrically transfer only a wave-length transferred light in a light sampling waveform observing device and method for observing the optical waveform in an ultrashort time region. SOLUTION: An optical signal (a) to be measured and a sampling optical pulse (b) are changed into either a linearly polarized light where the propagation in a nonlinear optical crystal 2 follows only Snell's law or a linearly polarized light crossing at right angles with the polarized light state using walk-off by birefringence of the nonlinear optical crystal 2 so as to be incident to the nonlinear optical crystal 2. This constitution spatially separates the sampling optical pulse (b) from the wave-length transferred light (SF light c). Then, the sampling optical pulse (b) is cut off so that only the SF light (c) can be received by a light receiver 4 by using a substance having low sensitivity to the wave length of the optical signal (a) to be measured as the light receiver 4.

IPC: G01S5/10
Filed: 1981-05-28
Abstract: PURPOSE:To enable surveying of a ship speed without a time lag at an arbitrary point of time, by a method wherein, using a first-in first-out system memory, a ship speed is computed from a value which is most early written in the memory and a value which is written lastly. CONSTITUTION:Using a first-in first-out system memory FIFO, a latitude value and a longitude value, into which a hyperbolic data is converted by a centralized processing unit CPU, are written in the memory FIFO each time said conversion is made, and a reading of the latitude value and longitude value, which are most early written, and the latitude value and longitude value, which are written lastly, is obtained by the CPU. Through computatin of a distance between spots decided by each latitude value and longitude value, a ship speed can be found. This permits survey of a ship speed at the same period as a period which coordinate-converts the hyperbolic data into a latitude and a longitude, and enables an error to be enoughly reduced through arbitrary lengthening of a distance between two spots from which a ship speed is found.
