IPC: G06F1/00
Filed: 1989-03-16
Abstract: PURPOSE:To reduce a load required for time control by storing request information in plural storage means corresponding to preset time, and performing the time control by monitoring only the request information stored first in each storage means. CONSTITUTION:A time control request means 111 sets a time in which the preset time is added on the present time as request time, and generates and outputs the request information including the request time and a request processing to be processed at the request time, and the request information is stored in either the storage means 121 corresponding to the preset time. A time control means 141 compares the request time in the request information stored first in each storage means 121 with the present time supplied from a present time measuring means 131, and when the request time arrives at the present time, an instruction to execute the request processing is issued. Thereby, since the time control is performed by monitoring only the request information stored first in each storage means 121, the load on the time control means 141 can be reduced.

The outflow of the driving current of the MI element 10 to the medium 1 side is prevented by the intervention of the insulating film and reproduction is executable without any problems.  In addition, an optimum size is selectable for the MI element 10 without being affected by the track width and gap width by the requested recording density. Optimum characteristics are thus obtd. and the execution of the good reproduction with the high sensitivity is possible.

Title: Signal processing system for optical disk device
Inventor: YOSHIMOTO KYOSUKE
IPC: G11B20/18
Filed: 1993-03-24
Abstract: PURPOSE:To prevent data from disabling the reproduction due to the synthesis at wrong timing by performing pattern detection after the synthesization. CONSTITUTION:Gates 121 and 122 are controlled by pattern coincidence pulse generating circuits 117 and 118 and when it is judged that respective preceding and following edge patterns are coincident, filtered signals are outputted to a synthetic OR circuit 123 and synthesized. The output of the circuit 123 is a pattern which is extracted successively from preceding and following edges and synthesizes data as they are. The output of the circuit 123 is exclusively ORed with a pattern filter 124 for detecting both of edges for each bit. When the patterns are not coincident, '1' is outputted and the number of this '1' is counted by a counter 125. A threshold value is set from a host device to this counter, this is monitored by a pattern detecting circuit control circuit 127, when the preceding/following edge pattern coincidence signal is active and the count value is smaller than the threshold value, switches 109 and 110 are closed by judging that the pattern is recognized even for the synthesized signal, and the synthesized signal is extracted from the circuit 123.

Title: Device and method for reproducing magneto-optical disk
IPC: G11B11/10
Filed: 1992-03-23
Abstract: PURPOSE:To provide a magneto-optical disk with high density and with large capacity without changing the wavelength of a laser beam by analyzing the polarizing condition of the reflected beam from the recorded part of a magnetooptical disk by a polarization analysis method and reproducing recorded information. CONSTITUTION:The laser beam from a laser light source 1 passes through a polarizer 2, a half mirror 3, an objective lens 4 and the image is formed on the magneto-optical disk 5. The reflected beam goes backward and reflected by the half mirror 3 and luminous flux is bisected by an optical flat 8 and are made incident on photodetectors 71, 72 respectively through analyzers 61, 62. The inclination angle of linear polarization is decided from the intensity ratio of the outputs of two photodetectors 71, 72. Thus, since the information is recorded corresponding to the inclination angle of a polarization surface, high density recording is performed. Further, the recorded information is reproduced without depending on the fluctuation of the incident light intensity of the laser beam to the disk 5 and the reflective index of the recorded part of the disk 5.

Title: Differential pressure detection device
Inventor: KITAMURA KAZUAKI
IPC: G01L9/12
Filed: 1995-03-24
Abstract: PURPOSE: To provide a differential pressure detection device which enhances the accuracy of a temperature correction by a method wherein a differential pressure detection part and a temperature detection part are brought close to each other so as to be set to an indentical temperature state. CONSTITUTION: Respective silicon plates 1 are arranged and installed, via respective insulating plates 3, on both sides of a measuring diaphragm 2 so as to be faced. A strain gage 4 is fixed and bonded to the edge of the silicon plate 1 on one side. The strain gage 4 is used primarily to detect a physical quantity such as a load, a pressure or the like, and it is changed according to a temperature because it is a resistor. Consequently, edge parts of the silicon plates 1 which are not subjected to a stress, i.e., whose strain is zero, are changed according to an ambient temperature. In other words, an ambient temperature can be detected by the resistance output of the strain gage 4. In an arithmetic circuit part, a differential-pressure arithmetic operation and a temperature-correction arithmetic operation are performed comprehensively on the basis of a capacitance.

Title: Pressure dome for measuring blood pressure
Inventor: TOOMASU PII SUTEFUNSU
IPC: G01L19/14
Filed: 1989-03-17
Abstract: PURPOSE: To prevent the damage of a spring for holding a pressure dome inside a transducer housing while limiting the bending amount of the spring by providing the pressure transducer with a spring member for clamping the pressure dome and a member for limiting the bending amount of the spring member. CONSTITUTION: A void 0' is formed on a wall W of the pressure dome, and a tongue T having an inner terminal part 8 and an outer terminal part 10 is formed between the edge of the void 0' axially away from a membrane M and the top of the wall W. Since a gap G exists between a T-shaped top part formed from a stop part and a T-shaped top part from a void 0", the tongue T can be bent away from the membrane M just for a prescribed amount. When the tongue T is bent to a desired limit, the gap toward the tongue is closed and it cannot move any more. Thus, since the tongue is prevented from being excessively bent when large force is loaded to the tongue, the tongue is not damaged.
