Title: Automatic controller of blanking timing
Inventor: TSUDA TOSHITAKA
IPC: H04L7/02
Filed: 1982-03-27
Abstract: PURPOSE:To select correctly and blank the center point of an input signal, by slicing the input signal in a fixed level and extracting the difference between the time from the rise point to the blanking point and the time from the blanking point to the fall point of the sliced input signal to delay the time difference. CONSTITUTION:A slicer 1 slices an input signal Ain in the reference level and feeds it to an FF2. A counter 9 starts its count-down synchronously with a control clock 3.84M at the rise of output Q of the FF2 and then performs count-up synchronously with the next clock 3.84M when the output Q of an FF6 has a rise. This count-up is discontinued with the fall of the output Q of the FF2. A difference discriminating  x >=2 circuit 10 receives the contents of the counter 9 when the count-up is over and delivers logic 1 when the difference is >= 2 to actuate FF11 and FF12. Thus a counter 13 is renewed by +1 or -1. As a result, a blanking clock selector 4 is controlled via a decoder 14 so as to produce correctly the blanking clock at the center point of the input pulse Ain.

Title: Ferroelectric liquid crystal composition and ferroelectric liquid crystal display
Inventor: ONISHI HIROYUKI
IPC: C09K19/58
Filed: 1989-02-27
Abstract: PURPOSE:To obtain a ferroelectric liquid crystal composition which provides a liquid crystal display having high quality by adding an organic material which incorporates ions to a liquid crystal composition which shows a ferroelectric liquid crystal phase, thereby preventing the threshold properties from being deteriorated. CONSTITUTION:An organic material which incorporates ionic impurities is added to a liquid crystal composition which shows a ferroelectric liquid crystal phase. By the addition, adverse influences by ions, for example, induction of twist which is caused by shielding by ions in the inner electric field and localization of ions by the inner electric field, are prevented, thereby stably providing good threshold properties. Therefore, deterioration of threshold properties by ionic impurities in a ferroelectric liquid crystal is prevented. A ferroelectric liquid crystal display which is made of the ferroelectric liquid crystal composition can exhibit good display properties. Also, since the composition is an organic material and can dissolve in a liquid crystal, it does not become a nuclei which causes lowering of specific resistance, disorder of orientation, crystallization, and the like, and it can effectively catch ion components to eliminate their influence.

Abstract: PURPOSE:To realize a big reduction of cost with use of an ordinary condenser lens, by compensating the speed distortion of a picture which is produced by a polarizing mirror used in a laser printer, etc. by means of one of the two beams of a semiconductor laser. CONSTITUTION:One of the 2-beam semiconductor laser 1 is used for recording a picture (shown by a dotted line), and the other one (solid line) is used for the synchronous signal. These outputs are polarized by the galvano-mirror 3 driven by the sine wave via the collimator lens 2. The recording beam forms an image on the photoreceptor 5 via the converging lens 4, and the synchronous signal beam is reflected and separated by the reflecting mirror 6. This separated beam is slectively reflected by the light shieldig stripe reflector plate 7 and detected by the laser photodetector 8 in the form of pulse output S which is proportional to the polarizing speed of the beam. The output S is then converted into the voltage by FVC9, and the modulated clock signal is controlled by VCO10. Thus the distortion of picture is compensated. At the same time, the output is controlled by the laser modulating circuit 11 to give a compensation to the volume of exposure.
