Title: Retrieving device of information track
Inventor: SHIRAGAMI KAZUHARU
IPC: G11B21/08
Filed: 1985-01-23
Abstract: PURPOSE:To retrieve stably a desired track at a high speed by phase-comparing the output signal of a converting means with that of a frequency generating means. CONSTITUTION:When the 2nd moving means shifts at a high speed the scanning position of the converting means in the direction practically vertical with respect to the track direction of a recording carrier by including the 1st moving means, an address area or sector separator area is previously stored in a memory means 91. When the signal controls a switch means 83, said means disconnects the output signal of the converting means for crossing a track inputted to a phase comparing means 84 in the address area or the sector separator area. When the input signal disappears, the phase comparing means 84 phase-compares by the output signal of the converting means inputted through an immediately before the switch means 83 and the phase comparing means. Corresponding to the phase error signal, a frequency generating means 86 is caused to control frequency, and the output signal of the frequency generating means 86 is counted by a counting means with said output signal as a track crossing signal.

Abstract: PURPOSE:To improve the charge and discharge cycle characteristic and the long-term reliability by using an electrolyte tube made of ion conductive high polymer, which includes a predetermined compound, and using a compound positive electrode and a compound negative electrode made of the same compound with the electrolyte. CONSTITUTION:A compound positive electrode 2 consists of the positive electrode active material, a conductive agent, an ion conductive high polymer compound and a bonding agent, and a compound negative electrode 4 consists of the negative electrode active material and an ion conductive high polymer compound and a bonding agent.
