Patent JP-S63282927-A (JP)
Title: Information processor
Inventor: YOKOTA MASAFUMI
IPC: G11B7/0045
Filed: 1987-05-15
Abstract: PURPOSE:To previously prevent already recorded information from being destroyed by judging whether information from the reflected light of a traveling light beam is recorded or not and recording the information by the succeeding light beam according to this judged result. CONSTITUTION:At the time of recording information, recording data 27 are supplied through an AND circuit 12 to a laser driving circuit 11. The circuit 11 drives a semiconductor laser 8 and the laser light flux of a strong luminous intensity is generated from the laser 8. By a laser driving circuit 10, the laser light flux of a weak luminous intensity is generated from the semiconductor layer 9. These beams of laser light are focused toward an optical disk 2 by an objective lens 5 and conversing spots 4 and 3 are irradiated on the same track. The detecting value of a reflected light by this spot 3 preceding the spot 4 is given to a recorded information detecting circuit 40 and when the recording information exists, a '0' signal is outputted from the circuit 40. This '0' signal is outputted to the circuit 12 and when the '0' signal is supplied, the data 27 is interrupted to be outputted to the circuit 11 by the circuit 12. Thus, the recording information is prevented from being destroyed.

Title: Inspection system for computer
Inventor: WATANABE NOBUHISA
IPC: G06F11/22
Filed: 1989-05-09
Abstract: PURPOSE:To attain easy and accurate inspection without requiring expert knowledge by allowing a maintenance man to issue a diagnostic instruction for instructing the execution of the representative function of an I/O device, allowing the I/O device to form a command group and parameters for executing the function and storing the formed contents in a main storage device. CONSTITUTION:When a diagnostic instruction displayed on a display device is selected by a keyboard or keyed from a panel by the maintenance man, an originating means 1 in a central processing part 11 generates a diagnostic instruction for commanding a device 13 to execute prescribed device operation. At the time of receiving the diagnostic instruction, a reading means 3 reads out a command word for executing the operation commanded by the diagnostic instruction from a storage means 12 and a storage means 5 stores the command word read out by the means 3 into the main storage part 12. A control part 6 extracts the command word stored by the means 5 from the main storage part 12 based upon a start instruction outputted from the processing part 11 and controls the operation of the device 13 in accordance with the command word. Consequently, the I/O device can easily and accurately be inspected.

Title: Frequency-analyzer
Inventor: TADA TAKESHI
IPC: G01H9/00
Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To return a vibration reflecting light beam to a noncontact vibrator at all times, by using a part of a parabolic mirror having a focus agreed with a rotational center of the object to be measured and reflecting the vibration measurement reflecting beam from the object in the same direction at all times. SOLUTION: An object 1 to be measured is fixed to a supporting jig. An internal movable mechanism is vibrated in a move direction shown by an arrow. The vibration of the object 1 is measured by a noncontact vibrator 10. A light beam 11 projected from the noncontact vibrator 10 is bent at a reflecting mirror 21 by 45 deg., thus hitting the object 1. The light reflected at a measurement face is reflected again at the reflecting mirror 21 and detected by the noncontact vibrator 10. In this case, the reflecting mirror 21 used is a parabolic mirror having a parabolic plane 20 partly cut and a focus F agreed with a rotational center of the object 1, and therefore the reflected light beam 11 is a parallel light even if the measurement face 1 is inclined.  An optical path length of the noncontact vibrator 10 and the measurement face 1 is made long, thereby reducing a shift of the reflecting light.

Title: Static discharge protection circuit with dynamic trigger means
Inventor: TOOMASU DANGAN
IPC: H03F1/52
Filed: 1994-05-06
Abstract: PURPOSE: To obtain a protecting circuit by which starting is executed in response to an electrostatic discharge state, without mutual interference with an integrated circuit by connecting a multiple continuous circuit of diode connected FETs between a bus and the ground and dynamically triggering a shunt element. CONSTITUTION: Rapidly increased current is permitted to flow in a signal pad during an electrostatic discharge(ESD) phenomenon, so as to charge the capacitance of the pad and a voltage in an ESD-protecting bus 17 is increased. When the voltage with respect to the ground plate 41 of the bus 17 is increased so as to exceed the threshold value of the multiple circuit 51 of diode connected FETs 51a-51g, the circuit 51 is turned on and then, a trigger FET 57 is turned on. Thus, the voltage of an inverter node 61 is decreased, a shunt FET 47 is turned on, and the bus 17 and the plane 41 are shunted. When the voltage between the bus and the ground is decreased, the circuit 51 is interrupted. However an FET 57 is turned off after a sufficient leakage of an electric charge which is captured by the node 53 and, then FET 47 is turned off. Therefore, IC mutual interference is reduced.

Filed: 1989-05-11
Abstract: PURPOSE:To provide an electromagnetic acceleration device capable of getting a high acceleration characteristic by a method wherein a missile is composed of an insulating main body of the missile, an armature for generating plasma under a high voltage and an insulating partition plate. CONSTITUTION:As a launched missile 12 reaches rail electrodes 1' and 1', an armature 10 is electrically energized to form a high electrical flow by a high voltage power supply 6, so that a missile 12 generates a Rolentz force directing toward an extreme end opening of a hollow frame 3', the missile 12 is accelerated and launched from the hollow frame 3'. At this time, the armature 10 is melted and evaporated by a Jule heat of electrical current and then evaporated gas containing plasma 8 is generated in a clearance formed between the main body 9 of the missile and the partition plate 11 and between the rail electrode 1', and the armature 10. Since the plasma is enclosed between the main body 9 of the missile and the partition plate 11, the plasma is expanded to prevent a current amount per unit area from being reduced and the Rolentz force generated at the missile 12 is kept as it is high and thus the missile 12 can get a high acceleration.
