Title: Power-up signal generation circuit
Inventor: GO EINAN
IPC: G11C11/407
Filed: 1997-12-12
Abstract: PROBLEM TO BE SOLVED: To promptly respond to a change of a voltage supplied from outside, by detecting levels of a substrate bias potential and a source voltage, and outputting an OR signal of the detected levels as an initial set signal for a memory peripheral circuit in a semiconductor memory device. SOLUTION: A semiconductor memory device generates an internal source voltage Vcc and a substrate potential Vbb on the basis of a power source supplied from outside. A power up signal generation circuit 100 outputs a detection signal 40a at a Vbb level detection part 40 when the substrate potential Vbb is lower than -2V, and outputs a detection signals 50a from a Vcc level detection part 50 when the internal source voltage Vcc is larger than Vref. A multi level decoder part 60 operates a NAND of the detection signals 40a and 50a and outputs as a power-up signal 60a to a RAM control circuit part 70 via an inverter. Accordingly, a change of the source voltage Vcc can be promptly coped with.

Filed: 1992-12-24
Abstract: PURPOSE:To attain cooling stop temperature control with high accuracy and with a simple equipment constitution by dividing a cooling zone into plural groups and changing the number of nozzles in a group in proportion to an acceleration rate or a deceleration rate without changing a water injecting nozzle flow and a cooling zone length. CONSTITUTION:A group 10 obtained when a multitude of cooling nozzles is divided into groups is composed of combinations of four control valves 11,12,13,14 having two nozzles each.

Abstract: PURPOSE: To improve moisture removal capability from a low pressure steam turbine operated at a low load by forming an annular moisture collection slot at one end of a turbine inner wall and connecting it with a pump outside of a turbine wall removing moisture from the moisture collection slot with a plurality of passages. CONSTITUTION: A moisture collection slot 26 is formed on an end face 28 of an inner casing 12 opposing to an annular channel 14.

IPC: G03B5/00
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To accurately compute the vibration detecting signal so as to obtain the accurate reference value by computing the reference value with the least square on the basis of the vibration detecting signal. SOLUTION: An angular velocity sensor 10 can detect the angular velocity during the time when a half-push timer 90 maintains the ON operation, and outputs the vibration detecting signal, which is detected, to an amplifying unit 20. The amplifying unit 20 amplifies the output voltage from the sensor 10, and outputs this output signal to a computing unit 30 and an integrating unit 40. The integrating unit 40 performs the integration so as to convert the angular velocity to the angular displacement signal. A pre-correcting lens 60 displaces the optical axis of the image forming optical system of a photographing device so as to correct the blurring. Reference value omega zero of the output signal of the sensor 10 is computed by the least square.  Even in the case where a drift component is included in the output signal, tendency of the drift can be checked, and the drift component can be followed. Consequently, omega zero can be accurately obtained, and blurring can be accurately corrected by a blurring correcting lens.
