Title: Semiconductor memory
Inventor: NAKAYAMA AKIO
IPC: H01L27/10
Filed: 1990-07-30
Abstract: PURPOSE:To decrease the number of power supplies to one by providing an outside cell plate bias supply circuit which applies the external voltage VSG to a cell plate electrode just with application of the VSG and furthermore gives no influence to an internal cell plate bias generating circuit. CONSTITUTION:When the voltage (VSG) is supplied to a pad P2 15, the voltage VSG - Vth is applied to a cell plate electrode, where the threshold voltage of an n type MOS transistor TR 8 set between the pad P2 and the cell plate electrode is referred to as Vth. Then the cell plate electrode is separated from an internal cell plate bias generating circuit (block A) 11. That is, the bias of (VSG - Vth) is applied to the cell plate electrode just with application of the VSG to the pad P2 15. Furthermore the voltage VSG is not transmitted to the block A 11 and the block A11 is never destroyed. Thus two power supplies so far needed at application of the external cell plate bias can be decreased down to just a single power supply.

Filed: 1981-12-17
Abstract: PURPOSE:To obtain a sliding contact material having an enhanced hardly dissipative property while inhibiting an increase in the contact resistance of an Ag- Zn alloy due to oxidation and maintaining the sulfurization resistance and lubricity by adding prescribed percentages of Zn and one or more among Pt, Ru and Pd to Ag. CONSTITUTION:This sliding contact material is made of an Ag-Zn alloy obtd. by adding 1-10wt% Zn and 0.5-2wt% one or more among Pt, Ru and Pd to Ag. Since the contact material has said characteristics, the hardly dissipative property of the contact chip of the commutator of a small-sized motor formed with the contact material is remarkably enhanced. An increase in the contact resistance of the Ag-Zn alloy due to oxidation is inhibited to provide low and stable contact resistance, so variance in the number of revolutions of the commutator is considerably reduced.

Filed: 1987-08-20
Abstract: PURPOSE:To execute effective control at an optimum tracking error voltage by selecting only one area out of four auto-tracking areas in a frame at the time of even-times speed reproducing to obtain a tracking error voltage. CONSTITUTION:In case of tracking four tracks A, B in the even and odd frames of heads 1a, 1b at the time of even-times speed reproducing, the head 1a can reproduce only auto-tracking ATF signals ATF1, ATF2 on the track A of the even frame. Since a part of the ATF2 is lacking, a high level reproduced signal can be obtained only from the ATF1.
