Title: Optical data-reproducing apparatus
Inventor: SANO AKIMASA
IPC: G11B7/00
Filed: 1993-12-24
Abstract: PURPOSE:To obtain an optical data-reproducing apparatus which reproduces signals at a low error rate even with a narrow distance of tracks, by lighting light sources with a time lag which can be turned ON/OFF independently of each other, and irradiating adjacent tracks. CONSTITUTION:Adjacent tracks of a data-recording medium are irradiated with light beams 70-72 projected from three light sources which can be turned ON/OFF independently. Reflected light beams are converted into electric signals at a photodetector 5, and guided to sample hold circuits 34-36. A timing control circuit 44 controls turning-ON/OFF of the three light sources and the circuits 34-36. That is, only when the light sources corresponding to the circuits 34-36 are lighted, the control circuit 44 turns the circuits 34-36 into a sampling state. When the light sources are turned OFF, the circuit 44 controls the circuits 34-36 in a hold state. Therefore, when data are to be reproduced at high velocity with the use of light beams, leaking and entering of data from the adjacent tracks is decreased, so that signals can be reproduced stably at a low error rate.

Filed: 1990-11-30
Abstract: PURPOSE:To enable a motion speed of a fluid to be measured using a heat ray flow rate meter and a motion speed and a motion trace to be measured simultaneously according to image information which is obtained by an infrared rays image pick-up device from a fluid which is heated by a heating wire and achieve a wide flow measurement. CONSTITUTION:A flow rate measurement count data when a heat rays flow meter 203 is ON is sent to a computer 201 in synchronization with ON/OFF of current of a probe 103 at a certain time interval by a switch 204 according to the signal from the computer 201. On the other hand, a characteristic quantity of an image including length and direction of a trace which is obtained by an infrared rays camera is digitized by an image processing device 202 and is sent to the computer 201. The computer 201 calculates the flow rate from the characteristic quantity with a rate data which is obtained by the heat rays flow meter 203 as a reference rate, thus enabling both the flow rate and flow trace to be measured simultaneously and achieving a wide range of measurement.

Title: Optical disk device
Inventor: TAKAHARA TAMANE
IPC: G11B21/08
Filed: 1989-12-21
Abstract: PURPOSE:To attain stable control with less phase delay by measuring an elapsed time from the point of time when a pulse is generated and calculating an output value which is larger between an output representing the elapsed time and an output value stored just before so as to obtain a relative speed. CONSTITUTION:An output of a latch 14 is larger than or equal to an output value of a CK counter 13 at all times at the acceleration or at a constant speed. Thus, a selector 16 selects an output value of a latch 14, that is, a time between a time when a new pulse is generated from an edge detection circuit 12 and a time at a preceding time generation in the current sampling timing depending on the output of a comparator 15 and outputs the result to a speed calculation circuit 17. On the other hand, the counter 13 measures an elapsed time from the pulse production point of time of the circuit 12 till a succeeding sample timing as a multiple of a period of a sample timing signal. Thus, the prediction of the relative speed is implemented early by one sample timing thereby improving the tracking performance.
