Filed: 1987-09-14
Abstract: PURPOSE:To enhance the contrast of an optical switch and reduce variations in the contrast, by using only a negative voltage pulse as a reset voltage, in driving a liquid-crystal optical switch for a printer. CONSTITUTION:Scanning voltages VC1... supplied from multiplexers 21-2N are applied to N scanning electrodes C1-CN, and time-sharing driving with 1/N duty is conducted. A CMOS-IC driver is connected to a signal electrode S1, a voltage pulse of -V0 +V0 or +V0 -V0 is applied according to a data signal D1, and optical switches 11, 12... are made to be in a reset period at -2V0, thereby preventing leakage of light. On the other hand, a voltage of +2V0 is applied in a holding period, so that a high contrast can be realized, and since it is possible to cause an average voltage to be 0 in one frame period, deterioration of a liquid crystal material does not occur. Thus, an optical switch driving method with little variations in contrast and with high reliability can be obtained.

Abstract: PURPOSE:To avoid the redundancy of transmission from being increased while eliminating spike noise based on an excess rate of change in a received data considered not in generation by discriminating whether or not a received waveform data pattern satisfies a prescribed condition in a waveform transmission by the PCM system such as an earthquake wave. CONSTITUTION:When the 1-th and the (i+1)-th data Si, Si+1 are held respectively by data holding sections 3-1, 3-2, a differential absolute value operating section 4 obtains the difference ¦DELTAS¦ of the both. A level + or - discriminating section 6 compares the ¦DELTAS¦ with a setting value ¦C¦ of a level setting section 5, and when ¦DELTAS¦<¦C¦, the holding of a data output of the Si+1 and the data of the next Si+2 to the holding section 3-1 is commanded to control sections 7 and 2. When ¦DELTAS¦>=¦C¦, the holding of the data output of the Si and the data of the Si+2 to the holding section 3-2 is commanded. When the data output and the holding of a new data are executed sequentially under the condition of ¦DELTAS¦<¦C¦, the holding of the new data is given alternately to the holding sections 3-1, 3-2 and outputted alternately from them. When ¦DELTAS¦>=¦C¦, the new data is substituted further into a newer data and the old data is outputted again.

Title: Control system for channel device
Inventor: KOYABU MASAO
IPC: G06F13/12
Filed: 1987-09-11
Abstract: PURPOSE:To improve the processing efficiency of the titled control system by shortening the interruption processing time in case a channel device gives a processing request to a channel processor and at the same time reducing the processing sequence between the channel device and the channel processor. CONSTITUTION:The processing sequence set between a channel device CH and a channel processor CHP can be finished by an answer given to the CHP from the CH and vice versa. While both an interruption request and the interruption contents are transmitted at one time and an answer of the CHP is waited for with the interruption processing given to the CHP from the CH. Thus the interruption processing time is shortened when a processing request is given to the CHP from the CH. At the same time, the processing sequence is reduced between the CH and the CHP and the processing efficiency is improved.

Abstract: PURPOSE:To provide a low-cost laser control device having a smaller number of components by employing a simple structure in which one combination of a current source and a D/A converter is connected selectively to the active side or monitor side of a laser source. CONSTITUTION:A laser control device includes current sources 2a-2c connected between the active side of a laser source 1 and a control section 6, and parallel- connected D/A converters 7a-7d that supply control signals to the respective current sources 2a-2c. The current source 2c is selectively connected to the active side or monitor side of the laser source through a switch 13. When the control section 6 allows the switch 13 to throw its pole onto a contact (b), a digital value corresponding to a laser current is read from a memory 10 and supplied to the D/A converters 7a-7d, while a comparator 5 controls the digital value to set either the maximum or minimum optical output. According to this control device, laser output can be varied in steps. In addition, since one current source is operated both for the minimum and maximum output, the number of components is reduced, thereby reducing the device cost.
