Title: Display device
Inventor: HOSHINO MASAFUMI
IPC: G09G3/36
Filed: 1995-03-02
Abstract: A display device is disclosed which includes a liquid crystal panel 1, a controller 2, a common driver 3 and a segment driver 4.  The controller 2, as well as producing an orthonormal signal derived using a set of orthonormal functions,  also produces  a  sum of product  signals  in accordance with a result of performing a sum of product calculations with a set of orthonormal functions and a set of pixel data.  The common driver 3 applies a row driving waveform having a predetermined voltage level (+Vr, Vo, -Vr) to the row electrodes of the liquid crystal panel 1 by group  sequential  scanning  at  selected  intervals  in accordance with the orthonormal  signals.   The  segment driver  4  applies  a  column  driving  waveform  having  a predetermined voltage level to the column electrodes of the liquid crystal panel 1 in synchronization with the group sequential  scanning and in accordance with the sum of product signals.  While the common driver 3 is supplied by a high voltage power supply  (+VLC, -VLC) and outputs a relatively high voltage level row driving wave form, the segment driver 4 is supplied by a low voltage power supply (VDD, GND) and outputs a relatively low voltage level column driving wave form.

Abstract: The present invention relates to a method pertaining to press filters of the kind which include a plurality of press plates (13). Pressure chambers (15), are formed between each pair of plates. A filter cake (16) is formed in each pressure chamber. Upon completion of the dewatering process the cakes are released from the chambers by separation of the press plates. The method is characterized in that emptying of the pressure chambers (15) is achieved by permitting each press plate (13) to rotate freely and swing about an axis (18) which extends generally horizontally through the plane of the plate, under the influence of the released filter cake (16). The press filter is constructed so that each press plate (13) is able to pivot in relation to the rails (14). The pulling devices by means of which the press plates are separated are attached to only one single coupling device (19) on each side of each press plate.

Title: Three phase motor conversion and monitoring circuit
Inventor: WERNER GARY A
IPC: H02P1/26
Filed: 1995-10-12
Abstract: A three phase motor conversion and monitoring circuit converts a three phase motor to be started and run on single phase line power.  During motor start-up, the circuit connects a start capacitor across a first input pair of the motor via a normally closed relay contact.  The circuit includes a power supply connected across a first motor input pair which powers both a voltage monitor connected across a different input pair and a phase sequencing detector.  When normal run voltage is detected across the first and second input pairs, and if and only if the phase sequencing detector has detected a normal phase sequence indicating that the motor is rotating in the correct direction, the relay is operated to open the normally closed contacts and to remove the start capacitor from the motor circuit.
