Title: Liquid crystal display device
Inventor: MINE HIDEKI
IPC: G02F1/133
Filed: 1992-05-18
Abstract: PURPOSE:To reduce deterioration in the life of the liquid crystal display device due to an applied voltage by providing a circuit which converts display data according to a specific rule in a data line driving circuit. CONSTITUTION:The bit data converting circuit 11 of the data line driving circuit 4 converts the display data by a rule which samples odd-numbered bit values of (n) bits, stores the sampled data values in order from the low-order bit, and sets the remaining high-order bits to zero. Namely, the odd-numbered data a(0), a(2)... of the display data a(0), a(1)... a(n-1) represented with (n) bits are sampled, the sampled data are stored in the low-order bits of a(0), a(1), a(2)4v a(n/2), and the data values of the high-order bits of a(n/2+1), a(n/2+2)... a(n-1) are all set to zero, thus performing the conversion. The digital values of the display data are converted into applied voltage values of a liquid crystal panel and then the applied voltage values are made uniform and suppressed low.

Title: Optical transmission system operating method, laser output power control method, and laser control circuit
Inventor: GNAUCK ALAN H
IPC: H04B10/293
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To provide an optical link control method and equipment by controlling a bias current which prevents errors caused by clipping at the time of a low temperature. SOLUTION: A control circuit to an injection laser supplies a pre-bias current for preventing errors in a laser output caused by clipping. An analog modulation signal is applied directly to a laser diode 10, and laser receives the sum of a feedback current Ifb and a current source Io as a pre-bias current Ipd. A monitor photodiode 14 detects the laser light output, and supplies a current Idet. The feedback current corresponds to the change of Idet, adjusts the laser pre-bias current in order to maintain Idet equal to a present value, and keeps effectively the average output power of laser constant. By preventing Ipb from becoming less than Imin, the errors and the distortions which are caused by clipping can be avoided.

Title: Offset voltage correcting circuit
Inventor: HORIE MASUMI
IPC: H03F3/34
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To correct the offset voltage of an operational amplifier without using a capacitor. SOLUTION: The output voltage of a D/A converter 20 is applied to the gate of a transistor 16 and constant voltage VDD is applied to the gate of a transistor 17. The D/A converter 20 changes voltage in accordance with the count value of a counter provided for a control circuit 19 and a comparator 25 compares the output terminal 3 and the non-inverted input terminal 4 of the operational amplifier 1. When the output of the comparator 25 does not change even if the count value reaches a prescribed upper limit value, switches 21-24 are changed over and the gate voltage of the transistors 16 and 17 is exchanged. When offset voltage becomes zero, the counting of the counter is stopped based on the output of the comparator 25 and the count value at that time is stored in the counter.
