Title: Information processor
Inventor: IHARA FUJIO
IPC: G06F13/362
Filed: 1994-07-26
Abstract: PURPOSE:To prevent use efficiency of a bus from being lowered even when there is the bus slave of low-speed processing in a system. CONSTITUTION:When requesting processing to bus slaves S1-S3, bus masters M1-M3 acquire the bus use right and issue processing request commands to the bus slaves and afterwards, a shared bus 1 is released. On the other hand, the bus slaves temporarily store the received commands addressed to them in queues, select any one of them and execute prescribed processing. After the end of processing, an answer command to the bus master of the processing request source is prepared, and a bus using request is issued to a bus arbitrating means 2. Concerning the read request commands continued inside the queue, its arrangement inside the queue is changed so that the higher the request level is set, the faster the command can be processed. Besides, the more the commands are stored in the queue, the higher the request level of the bus slave is set so that the use right of the shared bus 1 can be speedily acquired.

Title: Information reading device
Inventor: UCHIUMI YOSHIHIRO
IPC: G11B7/08
Filed: 1982-11-04
Abstract: PURPOSE:To prevent unnecessary vibration of an actuator, by installing separately a control means which adjusts the deviated amount of the actuator to a prescribed value when a tracking servo loop is cut. CONSTITUTION:A detector 30 is a sensor detecting the displacement of an objective lense 5 consisting an actuator in the direction normal to a track. A comparator 32 compares the output of the sensor 30 with a reference level 31 and its compared output is used as the drive signal of the actuator after it is switched and selected by means of a switch S1. Therefore, when a tracking servo loop is cut at the time of searching operation, the output of the comparator 32 is impressed upon the actuator and another servo loop constituted with the sensor 30, comparator 32, etc., is separately added. By the action of the loop, the deviated amount of the actuator is adjusted to a fixed value which is fixed by the reference level 31. As a result, unnecessary vibration of the actuator is prevented when the servo loop is cut and stable and high-speed searching can be performed.

Abstract: PURPOSE:To exactly execute the channel selection under the environment in which an optical frequency fluctuation exceeding a channel interval is generated by scanning a local optical frequency in one direction at the time of changing a channel, and monitoring the coincidence of a transmitting signal light and the frequency. CONSTITUTION:A light receiving part 30 multiplexes a local optical signal 202 from a channel selecting part 40 and an optical signal by an optical coupler 7, amplifies it by an amplifier 9 and obtains an intermediate frequency signal 201. On the other hand, at the time of changing a channel, a channel designating circuit 11-1 stops an intermediate frequency stabilizing circuit 10 through a switch signal 206, and scans a bias current 205, while monitoring an intermediate frequency signal 201. Subsequently, at the time point when an arrival to a target channel is detected, the scan of the current 205 is stopped, and by operating the stabilizing circuit 10 again, the channel change is completed. In such a way, by scanning the local optical frequency in one direction at the time of changing the channel and monitoring a passing channel, it is always possible to correspond to a transmitting optical signal, and even if a fluctuation is generated between the transmitting optical frequency and the local optical frequency, the channel change being free from a malfunction can be executed.

Title: Production of magnetic recording medium
Inventor: KAWAWAKE YASUHIRO
IPC: G11B5/84
Filed: 1988-08-03
Abstract: PURPOSE:To allow stable physical etching over a long length without generating wrinkling by moving a substrate along the peripheral surface of a cylindrical can and applying a potential difference between a thin film magnetic layer and the can, thereby executing physical etching. CONSTITUTION:The thin film magnetic recording medium 1 constituted by forming the thin film magnetic layer on a high-polymer film and further forming the thin magnetic layer thereon is moved along the can 6 via rollers 2, 3. After the inside of a vacuum vessel 7 is evacuated, a prescribed gas is introduced into the vessel and an electric discharge is generated between a positive electrode 8 and the medium 1 to execute the physical etching. The thin film magnetic layer is so formed as to come into contact with the rollers 2, 3 without coming into contact with the can 6 and a negative potential is impressed to the surface of the magnetic layer of the medium 1. The medium 1 sticks tightly to the can 6 in this way and does not wrinkle. In addition, the positive ions collide perpendicularly against the surface of the magnetic layer. The stable etching is thus executed while the surface ruggedness is maintained.

Title: Magnetic disk device
Inventor: IIDA MUNEO
IPC: G11B17/038
Filed: 1982-11-08
Abstract: PURPOSE:To prevent turbulence of air current and enable prevention of vibration of a magnetic head and disk by covering the outer periphery of the magnetic disk at specified intervals and providing an internal shroud having plural small holes through which air can circulate on the side wall. CONSTITUTION:Displacement in time of the amount of offset is different between the case where holes are provided in an internal shroud and the case where the holes are not provided. In the case where plural holes are provided on the wall of the internal shroud, heat generated inside escapes from the holes and temperature difference between inside and outside of the internal shroud lessens quickly, and the amount of off track becomes stable in a few minutes. As air current in the cover and air current in the shroud 13 cause convection through an air cleaning filter 12, clean air is always retained in the shroud 13. Dust that enters between floating distance of the magnetic head and magnetic disk 1 is reduced remarkably, and serious damage such as head crush can be prevented.
