Inventor: HACHMEISTER MARCEL
IPC: G05F1/10
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To improve check precision remarkably at the time of performing self-diagnosis of a current adjusting stage by making a current decided by an on-off ratio flow to a load, comparing quantity derived from the on-off ratio with a prescribed target value and detecting an error when deviation exists according to the comparison result. SOLUTION: A microcontroller 110 supplies a target value I1 to a current adjusting device 140 on a 1st current adjusting stage 100 and the device 140 measuring a real value of current flowing through a load L based on the voltage drop of measurement resistance R of a load circuit 120. The device 140 decides a control signal that is supplied to a switching means S based on the comparison of the actual value with the value I1. That is, corresponding current is caused to flow to the load L in dependence upon an on-off ratio n1 that is supplied to the means S, the ratio of the value I1 to the output on-off ratio n1 is compared with a prescribed comparison value in order to monitor the stage 100 and when deviation more than allowable range as the comparison result exists, an error is detected.

Title: Halide copper vapor laser
Inventor: OUCHI KAZUMI
IPC: H01S3/227
Filed: 1989-12-11
Abstract: PURPOSE:To acquire laser oscillation of stable discharge, high efficiency, high output and a small angle of beam enlargement by adjusting a discharge repetition frequency of a copper vapor laser using halide copper to 25kHz or more. CONSTITUTION:Any one of CuCl, CuBr, CuI is used as halide copper. A halide copper 1 is sealed inside a laser oscillating tube 2 having laser windows 4, 4 and discharge is initiated by applying a high voltage repeatedly between discharge electrodes 3, 3 attached to both ends of the oscillating tube 2. If a repetition frequency is increased, a current flows easily and ionization becomes hard, thereby stabilizing discharge. Furthermore, a laser light of regular gauss distribution is acquired due to bone effect which is a flow of current in a central part of the oscillating tube 2. Laser light emission of high efficiency and high output can be acquired at 25kHz or more, desirably at 25 to 40kHz of characteristics between laser output to a discharge voltage and efficiency using a repetition frequency as a parameter.

Title: Information recording medium
Inventor: OKAWA HIDEKI
IPC: G11B7/243
Filed: 1988-12-22
Abstract: PURPOSE:To provide a long-lived data recording medium even under circumstances at high temperature and humidity by forming a recording film of amorphous state which contains Cu, Te100-x(5<=x<=45 atomic %) alloy as well as carbon and hydrogen in a specific flow of a mixed hydrocarbon and rare gas atmosphere with the more amount of carbon in the part in contact with the substrate than that in the film, on the substrate. CONSTITUTION:A recording film 14 of amorphous state is provided on a substrate 13. This film contains an AuTe alloy in the flow X of a mixed hydrocarbon gas and rare gas atmosphere on a substrate and Cu, Te100-x(5<=x<=45 atomic %) alloy as well as carbon and hydrogen at less than 5<=Q<=50 % where Q={X/(X+Y)}X100%. The film also contains the more amount of carbon in the part in contact with the substrate than that of the film. If a film is formed at less than 5<=Q<=50 % (Q = flow rate), an optical absorption rate does not deteriorate due to the excessive amount of carbon C and hydrogen H. A recording film 14 reaches the minimum value of reflection factor due to a multiple interference effect, if the film is 1,000Angstrom  thick. If the film is changed from an amorphous phase (dispersed state) to a crystal phase (flocculated state) at that thickness, the reflection factor becomes significant and data can be recorded accordingly.

Abstract: PURPOSE:To precisely suppress sound even though a zero point or a deep dip is present in a frequency characteristic as one control transmission characteristic, by transmitting control sounds for suppressing sound with the use of a plurality of control transmission paths. CONSTITUTION:A detection signal for a noise detector 1 is inputted to adaptive filters 2, 4 from which outputs are issued from speakers 3, 5.

Where the speakers 3, 5 are set so that the characteristics C1, C2 are different from each other. Errors between the control sounds and the noise are detected by a microphone 13 and are delivered to multipliers 8, 11. Meanwhile, a detection signal from a noise detector 1 is subjected to computation by convolution computers 8, 9 having the characteristics C1, C2, and is then multiplied with the error signals from the microphone by the multipliers 8, 11. Thus multiplied values are inputted as coefficient updating signals to the adaptive filters 2, 4.
