Title: Liquid crystal display element
Inventor: HIRAI YASUNORI
IPC: G02F1/133
Filed: 1989-06-02
Abstract: PURPOSE:To obtain what is called a birefringence control type liquid crystal display element which makes a display by controlling birefringence by orienting liquid crystal molecules almost vertically when no voltage is applied, and varying the orientation state of the liquid crystal molecules. CONSTITUTION:The display quality of the birefringence control type liquid crystal display element depends greatly upon the product  nd of the birefringence  n of liquid crystal and the thickness (d) of a liquid crystal layer. In such a case, the range of proper  nd is 0.6 - 0.9mum and in this range, both the height of a contrast ratio and the width of a visual field angle are obtained. Further, the sum (R1+R2) of retardation values of two birefringent media needs to be set within a range of almost 120 - 560nm so as to maintain the contrast ratio and preclude a coloring phenomenon when the liquid crystal element is observed slantingly. Consequently, the bright liquid crystal display element which has the high contrast ratio even when observed slantingly over a wide range can be realized.

Filed: 1982-08-13
Abstract: PURPOSE:To increase a sentence input speed, by making a cursor for indicating a line position movable, in a reading table using a reading table for supporting an original and indicating an inputted line position, in case of inputting to a word processor, etc. CONSTITUTION:An original 2 is placed on a reading table 1', and a revolving speed of a motor 4 (a moving extent of a cursor 3) is set by a changeover switch 6 to match a line pitch of the original. When a sentence is inputted by one line portion, a cursor moving signal is transmitted to the motor 4 by depressing a moving key 8' of the cursor 3, which is provided on a keyboard part 8. By rotation of the motor, the cursor 3 moves on the original by a line pitch portion, and indicates a position of a sentence to be inputted in the next time. In this way, since the cursor for indicating a position of an input sentence can be moved, it becomes unnecessary for an operator to move the cursor at every line feed, and an input speed of a sentence can be increased.

Title: Method for controlling inverter of pulse width modulation type
Inventor: SUZUKI SHIGERU
IPC: H02P27/06
Filed: 1990-05-31
Abstract: PURPOSE:To suppress a current from fluctuating with a simple configuration, by sensing a regenerative current in the DC intermediate circuit of an inverter of a pulse width modulation type through using a current transformer, and by changing the output frequency of the inverter in proportion to the magnitude of the sensed value of the current transformer. CONSTITUTION:By a PWM signal, an inverter 1b is controlled, and a three-phase PWM output voltage Vabc is outputted, and further, an induction motor 4 is driven. Hereupon, when the current flowing through the induction motor 4 is changed, a regenerative current IR is changed. When the regenerative current IR is increased, the induction motor 4 is in a braking state. Therefore, when the regenerative current IR is increased, a sensed voltage Vd of a circuit 3 for sensing the regenerative current and a frequency command voltage Vi of an adder 6 are increased too, and the frequencies of a PWM signal S and the PWM output voltage Vabc are increased. Thereby, the braking state changes into a driving state, and since the regenerative current IR is decreased, a current oscillation is suppressed.
