Title: Display device
Inventor: SHIMIZU KAN
IPC: G02F1/133
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption for data transmission and to reduce distortion of a signal waveform in data transmission by converting display data into Gray code display data and transmitting this converted data. SOLUTION: Display data expressed in binary number and a synchronizing signal, etc., are inputted to a control device 20. The inputted binary display data is converted into the Gray code display data by a Gray code conversion circuit 24 in the control circuit 20, and is sent to bus-like transmission line paths 22 connected with X driver ICs 14. In the X driver ICs 14, the Gray code display data to the amt. of one scanning line is received, and then this Gray code display data is converted into binary expression by a binary conversion circuit, and is stored in a data latch circuit. Then, the display data converted into binary expression is converted into a driving signal of a matrix type liquid crystal display part 12 by a D/A converter, and hence each pixel of the matrix type liquid crystal display part 12 is driven by this driving signal.

Filed: 1984-03-21
Abstract: PURPOSE:To constitute a system which causes no system-down even if a fault occurs in one device, by a simple constitution, by providing a switch for switching transmitting and receiving lines to the upstream side and the downstream side, on each transmission control device connected in a shape of a loop. CONSTITUTION:Transmission control devices A-F are connected by right-turn transmission lines R1-R6, and left-turn transmission lines L1-L6, respectively, and constitute a loop-shaped data transmitting system. Each device transmits a confirming signal to the upstream side and the downstream side through a transmission processing circuit TXC, an inputting/outputting circuit TRC, a left-turn transmitting circuit LTX, and a right-turn transmitting circuit RTX. Also, the confirming signal from the upstream side and the downstream side is detected through receiving circuits RRX, LRX, the circuit TRC, and a reception processing circuit RXC, respectively. When the confirming signal from the upstream side is not detected, a CPU turns back a signal to the downstream side by switching a changeover switch SW and becomes a slave device. Also, when the confirming signal from the downstream side is not detected, it becomes a temporary master device and folds a signal to the upstream side by switching the SW.

Abstract: PURPOSE:To execute the positioning with high accuracy by using an ultrasonic motor operated by vibration for driving force, and controlling it by one period unit. CONSTITUTION:Four corners of a moving base 1 are notched, and ultrasonic motors 2 - 5 are attached thereto. In each motor, piezoelectric elements (lamination type which expands and contracts in the lengthwise direction) 6 - 8 are orthogonal to each other, a black 9 is attached to its intersection, and they become driving force generation sources of the motors 2 - 5. The motors 2 - 5 generate driving force in two directions in the surface on a base 10, therefore, the base 1 can execute a rotary motion, and also, a linear motion in any direction. The motors 2 - 5 are controlled by a motor position detecting system consisting of a laser measuring system 11, a semiconductor position detector 12, a divider 12 and a reflecting mirror 14, and a driving circuit 16 for controlling the motors 2 - 5 by one period unit, based on this information. A motor position detecting system containing a reflecting mirror 15 detects a motor position in the direction orthogonal to the previous detecting system. These two detecting systems output position information to the circuit 16, and the circuit 16 moves the motors 2 - 5 to prescribed positions.
