Title: Directional selector valve control device
Inventor: HAGA MASAKAZU
IPC: F15B11/08
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To improve, in a directional selector valve control device, the responsivity of a directional change-over valve exhibited at a low temperature when driving it through an electric-to-hydraulic transducer. SOLUTION: The directional selector valve control device 2 has an operating lever device 10, a controller 11, an electro-magnetic proportional valves 12a, 12b, and an oil temperature sensor 13. The controller 11 receives operation signals CTa, CTb from the operating lever device 10, and an oil temperature signal Y from the oil temperature sensor 13, subjects the operating signals CTa, CTb to a delay process, and outputs correction signals MDa, MDb, which have been subjected to the delay process, to the electromagnetic proportional valves 12a, 12b. The controller 11 has a delay processing portion 11a, and a time constant modifying portion 11b. The delay processing portion 11a subjects the operating signals CTa, CTb to a primary delay process using a time constant T, whereas the time constant modifying portion 11b decreases the time constant T as the oil temperature Y is lowered.

Title: Ground speed sensor
Inventor: JIEEMUZU JIYOSEFU FUERAN
IPC: G01S15/60
Filed: 1985-05-14
Abstract: The sensor comprises an ultrasonic transmitter and receiver and a processing circuit in which a phase-locked loop tracks the received frequency in order to indicate the speed of a vehicle over the ground. A circuit (18) provides an attenuated and phase-shifted replica of the transmitted signal. This is combined in a circuit (20) with the received signal (14) to cancel out a cross-talk component in the received signal. A low pass filter (26) and squaring circuit (28) provide a signal (30) for the phase locked loop which is substantially pure at the reflected and received signal frequency. It is therefore possible to compare this with a reference frequency corresponding to zero speed to provide an output signal with sign and magnitude indicating respectively the direction (forwards or reverse) and speed of movement of the vehicle.

Title: Surface light emitting device and method of monitoring its output
Inventor: YAKOBU MEIYAA HAMAA
IPC: H01S5/125
Filed: 1989-04-25
Abstract: PURPOSE: To eliminate the need for inserting a monitor into a light pattern by an arrangement wherein a light is emitted from a diffraction grating when a current is fed to a surface emission unit having first and second gratings of different period, the light is detected by the second grating and the current is controlled based on the output from the second grating. CONSTITUTION: At operating, a bias voltage of appropriate polarity is applied to first and second electrical contacts 30, 32 and a light is emitted from an active region 18. The light is partially emitted from an output grating 42 and from a monitoring grating 44. A detector, e.g. a array of CCD detectors, receives the light from the monitoring grating 44 and delivers an electric signal to a display where the output from the monitoring grating 44 is displayed. Consequently, the current supplied to the surface emission unit is initially regulated to a desired driving current by observing the output from the monitoring grating 44 and then it is corrected in order to compensate for aging or variation of the environmental conditions.
