Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To perform recording and reproduction in the disk proximity type head of a floating head or the like satisfactorily by allowing an optical disk substrate for performing recording and reproduction, by specifying the distance between a recording surface and a recording and reproducing head to be constituted of a material, having the loss tangent of not smaller than a specific value for reducing the vibration of the substrate. SOLUTION: In order to make smaller the amplitude of vibration to be generated when the force of the vibration from the outside or the like is applied to an optical disk, a material which easily absorbs energy of distortion to be applied to the substrate by the vibration of the substrate is used. Then, a loss tangent tan δ at 25 deg.C at a frequency 100 Hz is preferably 0.02 or larger and more preferably 0.05 or larger. When this value is 0.02 or larger, the energy of the vibration can be sufficiently absorbed to make the vibrating amplitude of the substrate smaller. Here, the upper limit of the tan δ is preferably 1.5 or smaller and more preferably 0.8 or smaller.

Inventor: ITO KOJI
IPC: H02H9/06
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To prevent the breakdown of a telephone-line switching device and to eliminate the risk of electric shock by adopting the circuit constitution, wherein the thunderbolt surge current generated on the falling of a thunderbolt does not flow into the telephone-line switching device but securely flows through the signal line in the equipment. SOLUTION: A pattern gap 24 and varistors D2 and D3 are connected between both electrodes (or one-side electrode) of an AC power supply 7 on the primary side and between tuner grounds on the secondary side. Furthermore, the gap interval of the pattern gap 24 is narrower than the specified value so as to guide the thunderbolt surge current. In this case, the operating voltage at the varistors D2 and D3 and the gap interval of the pattern gap 24 are set so as to start the discharge at the voltage higher than a dielectric strength test voltage, in order to obtain the dielectric strength required for the specification. Thus, the thunderbolt surge current generated on the falling of the thunderbolt is not divided to flow to the side of a circuit switch 9 and can be guided to the ground through a thunderbolt protection device 23 in a television receiver 21 and discharged securely.  The breakdown of the other equipment can be prevented.
