Abstract: A method of driving a liquid crystal display element in which a switching element is provided for each of pixel electrodes arranged in a matrix manner and a ferroelectric liquid crystal is sandwiched between the pixel electrodes and a counter electrode includes the steps of applying a reset voltage for resetting the entire pixel to a first stable state of the ferroelectric liquid crystal across the pixel electrode and the counter electrode, partially transiting the pixel to a second stable state by a tone signal voltage having a pole opposite to that of the reset voltage, and reversing the pole of the reset voltage every predetermined period. Assuming that a state reverse ratio of the ferroelectric liquid crystal is T(V)% when the tone signal voltage is V, a tone signal voltage V₁ after negative resetting and a corresponding tone signal voltage -V₂ after positive resetting satisfy the following relation: 
 
       T(V₁) + T(V₂) = 100

Title: Liquefied gases expansion apparatus
Inventor: SCHMIDTKE WOLFGANG DIPL-ING
IPC: A23L3/375
Filed: 1991-10-09
Abstract: A device for the expansion of a liquefied gas is described, e.g. for cooling a freezer space. By means of a liquefied gas pipe 3, the liquefied gas is conducted to a flow splitter 5 which divides the liquefied gas flow into two branch pipes 6, 7. One branch pipe 6 ends in a gas pressure accumulator 8 while the other branch pipe 7 has expansion bores 9 for expansion of the liquefied gas. The gas pressure accumulator 8 ensures that, even after the liquefied gas supply has been switched off, the liquefied gas in the branch pipe 7 is kept at a pressure above the triple point of the liquefied gas. In this manner, in particular in the case of use of carbon dioxide as liquefied gas, blocking of the branch pipe 7 by frozen carbon dioxide ice is avoided. <IMAGE>

Abstract: A photo-interrupter includes a light emitting diode (11), first and second phototransistors (12-1, 12-2) and comparator (18). The light emitting diode (11) and the first and second phototransistors (12-1, 12-2) are arranged so as to be optically coupled with each other. Light emitted from the light emitting diode (11) is directly received by the first phototransistor (12-1) and a first photoelectric current used as a reference is generated from the first phototransistor (12-1). The second phototransistor (12-2) generates a second photoelectric current corresponding to the amount of light transmitted through a to-be-detected object when the to-be-detected object is put into an optical path ranging from the light emitting diode (11) to the second phototransistor (12-2). The first and second photoelectric currents are respectively converted into first and second voltages by means of first and second resistors (21, 20). The comparator (18) compares the first and second voltages with each other and outputs a signal indicating the presence or absence of the to-be-detected object.

Abstract: The invention relates to a method for determining and regulating the liquid metal level in a metallurgical vessel, especially an open-ended die of a casting plant. In order to provide a method in which the liquid level can be determined and regulated in a simple and reproducible manner, it is proposed that inert gas be introduced into the molten metal at a certain freely selectable point within the vessel, that the flow rate and absolute pressure of the inert gas introduced be measured, that the absolute pressure measured when the zero value of the flow rate is exceeded be recorded and the actual value of the distance of the surface of the liquid from the point at which the inert gas is introduced be determined from the difference between the absolute pressure and the pressure acting on the surface of the liquid, that the difference from a predetermined setpoint value be determined from the said distance ascertained and fed as an electric actuating signal to an actuator for regulating the liquid metal level and/or the quantity flowing out or withdrawn from the vessel.

Abstract: In a semiconductor memory device, a transfer gate (TG) is disposed for each bit line (BL), which classifies the bit lines, word lines (WL), and memory cells (MC) at intersections therebetween into a plurality of groups. In a memory operation, portions of bit lines not employed in the operation are disconnected from the sense amplifiers (12), which prevents charge and discharge operations from occurring therethrough. Consequently, the current which is caused by the charge and discharge operations through the bit lines and which constitutes most of the current in the memory device can be minimized, thereby reducing the total current flowing therethrough.

Abstract: To control the operating parameter of a driving motor, the reaction torque which arises in the stator when the rotor is subjected to a load is used as the control variable. For this purpose, the stator of the driving motor is mounted rotatably and in a resiliently supported manner relative to a fixed body. In this way, it is possible to perform proportional or non-proportional adjustment. According to a further illustrative embodiment, control of the output or speed is carried out as a function of the pressure prevailing in the motor cylinder. This pressure is fed to a transmitter which acts on the conventional throttle-valve linkage of the motor control. Finally, control can also be carried out as a function of the position of the throttle valve or of the throttle-valve linkage. <IMAGE>

Inventor: MCCLURE DAVID CHARLES
IPC: H03K19/003
Filed: 1992-12-16
Abstract: A push-pull output driver circuit is disclosed which includes control circuitry for controlling the gates of the driver transistors to effect precharge of the output terminal at the beginning of a cycle. Precharge is initiated at the beginning of each cycle, for example indicated by an address transition. The prior data state at the output is stored, and enables the opposing driver transistor from that which drove the stored prior data state by enabling a gated level detector with hysteresis, such as a Schmitt trigger, associated therewith. The transistor that drove the stored prior data state is disabled, thus precluding oscillations during precharge. The gated Schmitt triggers each receive the voltage of the output terminal and, when enabled, turn on a transistor which couples the output terminal to the gate of the driver transistor. The Schmitt triggers also control the precharge to terminate when the output terminal has reached an intermediate voltage, and so that oscillations are minimized as a result of the hysteresis characteristic. Connection of the output terminal to the gate of the precharging driver transistor helps to eliminate overshoot during precharge.
