IPC: G02F1/137
Filed: 1989-05-12
Abstract: PURPOSE:To improve a contrast ratio greatly by setting a cell gap (d) to <=5mum and further determining the spiral pitch P of liquid crystal in specific relation with the ratio of the cell gap. CONSTITUTION:The TN liquid crystal 5 is charged between two upper and lower substrates 1 and 2 which have electrodes and polarizing films 3 and 4 are arranged on the outside surfaces of the upper and lower substrates 1 and 2 to constitute the field-effect type liquid crystal shutter, and the inter- electrode distance (d) of the substrates 1 and 2 is set to <=5mum. Further, the density of chiral nematic liquid crystal is so adjusted that 1.08<=d/P<=1.20 holds when the spiral pitch P of the TN liquid crystal 5 is less than 5mum cell thickness. Consequently, the ratio of the ON light quantity and OFF light quantity of the liquid crystal shutter, i.e. the contrast ratio can be improved greatly to increase the duty ratio, thereby obtaining excellent character quality on an electrophotographic printer.

Inventor: MATSUMURA KENZOU
IPC: G11C11/34
Filed: 1982-07-12
Abstract: PURPOSE:To attain high speed write to a memory cell, by adding selectively a constant current to a circuit forming a symmetrical tri-state voltage to a readout reference voltage. CONSTITUTION:A constant current I0' flows to a transistor (TR)Q7, since the TRQ7 turns on in a differential circuit (Q5-Q7) provided newly at readout in a write circuit WA. Thus, a reference voltage Vrefc for readout is -(2R1+2R2)I0- VBE. An input signal DIN goes to a high level according to the write data to a reference voltage VBB at write, the TRQ5 (or Q6) turns on and the constant current I0' flows to said resistance circuit, then a voltage VWH is suppressed lower by a voltage drop of resistors R1, R2 resulted from the addition of the constant current I0' newly, and since a voltage VWL is decreased (increased) by the share of the voltage drop of said resistor R1, the voltage is unsymmetrical to the voltage Vrefc. Thus, TRs Q10, Q11 are turned off strongly with the low level write voltage VWL to realize the high speed write to the memory cell.

Filed: 1987-05-20
Abstract: PURPOSE:To suppress the waveform distortion of a data output signal in a small amount, and to prevent a malfunction in a logic circuit in the subsequent stage by connecting resistors in series with the bases of first and a second transistors. CONSTITUTION:A latch circuit is constituted of a couple of the transistors 108, 109 whose bases and collectors are connected via an emitter follower 106. And the bases of the transistors 108, 109, are connected in series with the resistors 110, 111. By means of these resistors 110, 111, the response time of the latch circuit 105 is made slower, so that, even if the potential-relation between VS0, VS1 temporarily inverts because of the linking of a sense output, the latch circuit 105 itself does not cause malfunction. In such a way, the waveform distortion of a data output signal can be suppressed in small amount.
