Title: Lightning arrester
Inventor: ISOBE SHINJI
IPC: H01C7/12
Filed: 1988-10-11
Abstract: PURPOSE:To prevent inner components from slipping out to the outside of a lightning arrester by providing a barrier, which passes gas jetting out upon operation of a pressure releasing device and catches the inner components flying together with gas, near the pressure releasing device of the lighting arrester. CONSTITUTION:Gas 6 such as air-nitrogen, etc., is charged into an insulating vessel 1, and in case that a nonlinear resistor 2 fails and grounding occurs inside a lightening arrester, the gas 6 is heated and expands by the energy of that arc, and the pressure inside the insulating vessel 1 rises. At this time, a pressure releasing device 5 operates to prevent the bursting of the insulating vessel 1. That is, a pressure releasing part 501 opens, and heated and expanded gas 6 is released according to the release course of gas shown by the arrow A which is constituted by cover 7. And near the pressure releasing device 5 a barrier 9 which is fixed to the cover 7 receives inner components or broken pieces flying with released gas 6, for example, a nonlinear resistor 2 or its broken pieces, so those solid broken pieces are not released to the outside and only gas 6 is released to the outside.

Title: Disk drive device and its control method and information- processing device
Inventor: KOMAMI TAKUYA
IPC: G11B19/20
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To reduce vibration according to such condition as angular velocity by changing a drive substrate and at least one viscoelastic member being mounted to the substrate to viscoelastic characteristics according to the condition. SOLUTION: When vibration is generated by the rotation of a disk 8, the vibration is attenuated by a viscoelastic member 5. In this case, since a control circuit 7 controls a disk rotation means 2, it can grasp the speed of the disk along with the control and gives an instruction so that the characteristics of the viscoelastic member 5 reach specific ones for a characteristic-changing means 6 based on the value. The characteristic-changing means 6 changes the viscoelastic value of the viscoelastic member 5 according to the control and as a result the viscoelasticity of the viscoelastic member 5 can be controlled. As the above operations are performed continuously, attenuation characteristics can be optimized according to the condition of an angular velocity.  Then, by changing the natural frequency of the viscoelastic member 5, damping effect can be obtained at both low-frequency and high-frequency bands.

Title: Remote supervisory and controlling device
Inventor: TANAKA SHIGEHIRO
IPC: G05B23/02
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To transmit other data without giving any effect to normal data transmission by converting state supervisory station information of the opposite station into a multi-frequency code signal (DTMF) and providing a transmission line with a signal conversion transmitting means to transmit it. SOLUTION: When the information like a device state of a slave station is extracted from a master station, a signal converting part 7 converts data of the master station to be sent into a DTMF code and it is sent by a DTMF signal transmitting and receiving part 6. When the slave station received it, a filter 3 separates a sound band from a modulation demodulation signal band, and makes the state of devices that is transmitted as a code in a DTMF signal recognizable as state information of various devices. In this way, sending the state information of various devices as a DTMF signal to a transmission line enables historical transmission of device states to the opposite station. It enables transmission of state information without depending on normal data nor being depended on by the normal data regardless of regular or irregular information.

Title: Magnetooptic recorder/reproducer
Inventor: KANEKO SHINJI
IPC: G11B11/10
Filed: 1994-10-21
Abstract: PURPOSE: To reproduce data at an address part correctly. CONSTITUTION: A recording medium pre-coded with an address data is irradiated with laser thus reading the address data and recording/reproducing data at the data recording section. A light intensity signal flowing into a photodetector 40 for detecting the reflected light of laser is fed through a capacitor C to a first preamplifier 83 which outputs a reproduction signal at an address part. A shunt circuit 85 for light intensity signal is connected at the prestage of a capacitor and functions to lower the input gain of the first preamplifier when a data is reproduced or recorded at the magnetooptic recording section. Consequently, the DC level difference between the address section and the data recording section is decreased thus producing a decreased differentiated waveform.  Since the fluctuation of zero-cross level is suppressed in a comparator for demodulating the data, demodulation error of data is eliminated and the data can be reproduced correctly.
