IPC: H03L7/06
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To shorten time for reaching a target frequency by storing the relation of a control voltage and an oscillation frequency, applying a difference between the oscillation frequency based on the control voltage held immediately before interruption and a reference signal frequency to the stored relation and deciding the control voltage when interrupted reference signals are supplied again.

Title: Memory device and its testing method
Inventor: BROX MARTIN
IPC: G11C11/408
Filed: 1998-12-17
Abstract: PROBLEM TO BE SOLVED: To apply a turn-off voltage with a different value to the word line of a memory array by selectively applying a turn-off voltage to a row conductor, turning off the continuity of the main conduction path of a transistor where a gate electrode is connected, and selectively applying an increased turn-off voltage. SOLUTION: A word line WL is clamped to a node 41 via a transistor N1 or a transistor N2 for conditions where a signal RDEC or a signal WLK is high. The voltage of a node 41 becomes equal to the ground potential and Vbb volt when a signal TM is low and high, respectively, thus applying the ground potential or the Vbb volt to the word line WL. For conditions where the signal RDEC and the signal WLK are low and a signal WLD is high (for example, VDD volt), a high-level signal is applied to the word line WL, thus turning on an N-type memory cell transistor where a gate is connected to the word line W.

Abstract: PROBLEM TO BE SOLVED: To drive a liquid crystal display element which has large pixel capacity with a high write rate and low power consumption. SOLUTION: MOSFETs(metal oxide semiconductor field effect transistor) 1 to 4 are cascaded and the connection node of the MOSFETs 2 and 3 is regarded as an output terminal for a data signal to a data line DL of a TFT liquid crystal display element.

The image signal is inverted in polarity, frame by frame, and one of the MOSFETs 1 and 4 is turned off according to the polarity to prevent a through current.  The polarity of a common electrode voltage Vcon is also inverted by the frames for driving so that writing operation of each frame serves for the precharging of writing operation of a next frame.

IPC: F16D48/02
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To reduce a shock associated with variation in acceleration of a vehicle upon disengagement of a clutch. SOLUTION: In this method of controlling a clutch, the disengaging operation and the engaging operation of a clutch which is interposed between an output shaft of an engine on the vehicle and an input shaft of a transmission so as to turn on and off the torque transmission is controlled in accordance with an operating condition with the use of actuator. In this arrangement, when a demand for shifting the transmission is detected, the clutch is set by the actuator into an instant releasing condition (instant clutch disengagement) from a completely engaging condition, and is then set into an incompletely engaging condition. After the incompletely engaging condition is held for a predetemtined set time, the clutch is completely disengaged by the actuator.  With this arrangement, a first time inflection point on a characteristic curve of vehicle acceleration is present when the vehicle acceleation becomes substantially zero, and variation in the vehicle acceleration which occurs thereafter is converged in the vicinity of substantially zero.
