IPC: G11B7/125
Filed: 1987-10-27
Abstract: PURPOSE:To control the intensity level of reflected luminous flux to be always constant by reflecting a laser beam projected from a laser light source from a recording medium, diffracting the beam by a diffraction grating and controlling the intensity of the laser beam based on the intensity level of the reflected luminous flux. CONSTITUTION:The titled device 21 is provided with a collimator lens 23 collimating the light projected from a semiconductor laser 22 of a laser light source, the collimated luminous flux is collected on a recording medium 24, a beam spot is formed to fetch the reflected luminous flux onto an objective lens 25. The fetched reflected luminous flux is diffracted from the diffraction grating 26. On the other hand, the reflected luminous flux diffracted by the grating 26 is received, and converted into an electric signal by a reflected luminous flux intensity detector 27 and a photodetector 28. In response to the output from the detector 27, the intensity of the laser beam projected from the laser light source is controlled by a controller 29. Thus, the intensity level of the reflected luminous flux is made always constant.

Title: Data processor
Inventor: SAKAI SATOSHI
IPC: G06F12/00
Filed: 1989-10-18
Abstract: PURPOSE:To set up an optional waiting time by storing waiting time length information to be set up in a transfer period from a 1st stage to a 2nd stage which is outputted by an instruction from a data processor and outputting a stepping signal based upon the stored information. CONSTITUTION:In the data processor having a processing means for starting the reading of a memory in the 1st stage, and at the time of inputting a stepping signal, shifting operation to the 2nd stage and executing processing based upon the read data, the waiting time length information outputted by an instruction from the data processor so as to be set up in the transfer period from the 1st stage to the 2nd stage is stored in a storage means 3. Since an output means 4 outputs the stepping signal based upon the length information stored in the means 3, a processing means 2 can shift the 1st stage to the 2nd stage after the waiting time specified by an instruction. Since the waiting time of an optional time can be set up after starting the reading of the memory 1, the reliability of the data processor can be improved by changing the setting of the waiting time in accordance with a condition.

Filed: 1987-10-27
Abstract: PURPOSE:To obtain a headphone with excellent productivity and conversion efficiency by arranging oppositely a diaphragm and electromagnet made of a superconducting material so as to give a gap by the Meisnner effect and controlling the generated magnetic field corresponding to a voice signal thereby driving the diaphragm. CONSTITUTION:In giving a current corresponding to the voice signal and the music signal to an electromagnet 2 via a lead wire 4 and a terminal board 9, a magnetic field H is generated and a magnetic flux density B is caused. The diaphragm 1 cooled by a liquid nytrogen is arranged orthogonal to the magnetic field H, then the diaphragm 1 and the electromagnet 2 are repulsed together by the Meisnner effect. The repulsive force is proportional to the current flowing to the electromagnet 2. Thus, in giving a current to the electromagnet 2 corresponding to the voice signal and the music signal, the diaphragm 1 is displaced corresponding to the voice signal and the music signal. Through the constitution above, it is not required to fix the voice coil in the magnetic air gap with high accuracy, the yield and productivity are improved and the conversion efficiency is improved.

Abstract: PURPOSE:To provide a practically used and easily constituted picture correlation arithmetic unit, in which a detecting precision can be improved without increasing a calculating amount so much. CONSTITUTION:A correlation arithmetic circuit 14 operates a correlation arithmetic operation between the first picture picked-up and recorded by a charge modulating element(CMD) camera 10, and read out according to an arbitrary reading address set by a CPU 18, and the previous frame picture as the second picture read out from a memory 16 by the arbitrary reading address of an address generating circuit 20.

IPC: H02P27/04
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To reduce a variation in temperature in a show case, keep a freshness of a cooled item and prevent a life of equipment from being reduced by a method wherein there is provided an inverter controller in which a target control temperature for use in driving an inverter is shifted to a higher temperature than an operation finishing point of a solenoid valve for liquid. SOLUTION: In the case that a target temperature of a show case is 0 deg.C, an operation finishing point of a solenoid valve for liquid is set to -1 deg.C shifted to a minus side by several degrees (for example, 1 deg.) at a show case controller and concurrently 2 deg. is set as a temperature adjustment differential. Accordingly, in this case, an operation finishing point of the solenoid valve for liquid becomes 1 deg.C. As a reference temperature for use in calculating a deviation in temperature, toe inverter controller sets -0.5 deg.C in which an operation finishing point -1 deg.C of the solenoid valve for liquid in the show case is shifted to a higher temperature side by a predetermined value (for example, 0.5 deg.).  In this case, a speed increasing zone of the number of rotation of a compressor motor shows 0.5 deg.C or more, a constant speed zone of it shows 0 to 0.5 deg.C and a speed reducing zone of it shows 0 deg.C or less.
