Title: Readout control circuit for semiconductor nonvolatile memory
Inventor: FURUTA MASAO
IPC: G11C17/00
Filed: 1981-01-20
Abstract: PURPOSE:To achieve the best setting of a readout voltage for storage holding time, by controlling the readout voltage of a nonvolatile memory by an inverter circuit consisting of a nonvolatile memory which has nearly the same characteristics with said memory. CONSTITUTION:A load resistance having a little bit less resistance value than the load resistance 4 of a nonvolatile MNOS transistor (TR) 9 for data storage is connected and when the readout voltage of a nonvolatile MNOSTR8 having a little bit lower readable range than the TR9 and nearly the same characteristics with the TR9 is small and the TR is turned off, an MOSTR11 forming an inverter together with the TR9 and an MOSTR10 is turned off. consequently, a capacitor 13 for integration is charged up to a prescribed voltage, and then the TRs 8 and 9 turns on through a circuit block 14 for control, thereby discharging the capacitor 13. Therefore, the readout voltage of the TR9 is set automatically to the best desired value for storage holding time, and the storage holding time of the nonvolatile memory is improved substantially.

Title: Wavelength-selectable optical signal processor
Inventor: ROORENSU JIEI RENBOO
IPC: G02B6/28
Filed: 1995-01-23
Abstract: PURPOSE: To provide a wavelength selectable optical signal processor which can generate a predetermined delay pattern in a signal. CONSTITUTION: A system contains a series of light delaying paths 16. Each path 16 receives part of a modulated light beam 20 having a predetermined wavelength. The moving distance of each beam 20 along the path 16 changes as a function of the predetermined wavelength of the beam 20. Consequently, the optical path length of an arbitrary predetermined wavelength forms a predetermined delay pattern over the light delaying paths 16. When this system is applied to signal processing, a high-speed processor using a traversal filter design which can recouple wavelengths can be constituted by superposing time- delayed signals upon another, because a delayed light beam can be recoupled in a time domain.  When this system is applied to a phased array antenna, a time delaying network in which the direction of an antenna beam corresponds to the wavelength of a light carrier one to one can be constituted.
