Title: Liquid crystal optical element formed by using ferroelectric high-molecular liquid crystal and its gradation display method
Inventor: ENDO HIROYUKI
IPC: G02F1/133
Filed: 1993-03-25
Abstract: PURPOSE:To enable gradation display by using >=2 kinds of specific ferroelectric high-molecular liquid crystals and forming microdomains varying in nature within the liquid crystal optical element. CONSTITUTION:The ferroelectric high-molecular liquid crystals are >=2 kinds, are insoluble with each other and exist by dividing in microdomains. For example, threshold voltages are assumed to differ from each other to the pulse of the same pulse width when there are the domains of liquid crystals A, B within the single electrode. Neither of the liquid crystals invert and the liquid crystals are in a dark state at the time of impressing a voltage V1. Only the liquid crystal A inverts and a medium contrast viewed as a whole of the pixels is resulted at a voltage V2. Both liquid crystals invert and a bright state is attained at a voltage V3. Three-gradations are thus possible. More specifically, the gradation display is attained if the threshold voltages vary by >=0.1V. The mutually insoluble high-molecular liquid crystals in which the microdomains varying in nature are to be formed, are selected from, for example, a polyacrylate system, polymethacrylate system, etc.

Title: Crt display device
Inventor: SAWADA AKIRA
IPC: H04N5/68
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To obtain best focus performance, regardless of the change in a beam current of a cathode-ray tube(CRT) (change in luminance of a screen). SOLUTION: A pulse voltage, obtained in a secondary winding 10 (10a, 10b) of a flyback transformer 7, is rectified and smoothed by a diode 11 (11a, 11b) and a capacitor 12 to obtain a high voltage EHV of a CRT, and the voltage is resistance-divided at a fixed resistor 13, a variable resistor 14, and a fixed resistor 18 to produce a static focused voltage EF1 . The fixed resistor 18 is connected in series with the secondary winding 10, so as to change voltage at a connecting point A between the variable resistor 14 and the fixed resistor 18, depending on a beam current iB. Thus, the static focused voltage EF1 obtained from the variable resistor 14 changes with a change in the beam current iB, so that even if the beam current iB changes, the static focused voltage EF1 is controlled so as to maintain best focus performance.

Title: Image forming device
Inventor: ANDO MAKOTO
IPC: B41J2/525
Filed: 1995-04-14
Abstract: PURPOSE: To eliminate useless time for detecting a test pattern(TP) and performing a resist deviation correction and to efficiently perform a deviation correction by performing the detections of the both of sub/main scanning patterns for the N-Ath of the TPs of N colors. CONSTITUTION: A program is started by a control means 21. A CCD driver 32 is set to detect sub-scanning patterns. A sample number of times counter showing the number of times of detection is cleared and the counter is made an initial state. The counter(n) of the sample number of times is made incremental. Namely, this counter is successively made incremental from the state of 0 to 1, 2, 3 and 4. Next, the sub-scanning patterns of the test patterns are successively detected in order from K. Whether the counter n becomes N or 4 or not is judged. In the case of Yes, the CCD driver 32 is switched from the sample of the sub-scanning pattern to the detection of the main scanning pattern. The main scanning patterns of a formed test pattern are successively detected from the C test pattern from which the sub-scanning pattern is detected last of all.  Thus, the main scanning patterns of the 4-color test patterns of a KYMC is detected in order of CKYM.

IPC: C07C1/20
Filed: 1979-07-16
Abstract: PURPOSE: A mixture containing tertiary butyl alcohol and tertiary butyl ester of aliphatic carboxylic acids is treated with an acidic ion-exchange agent to inhibit the decomposition with the carboxylic acids formed and distilled to give high- purity isobutylene.  
     CONSTITUTION: A mixture containing tertiary butyl alcohol and tertiary butyl ester 1W6C aliphatic carboxylic acids, e.g., a mixture recovered from the reaction mixture resulting from the hydration of a hydrocarbon mixture containing isobutylene using 1W6C carboxylic acids in the presence of an acidic ion-exchange agent, is treated with an acidic ion exchanger and the resulting reaction gas is distilled to give isobutylene. The treatment is effected at 60W120°C and normal pressure to 4.5kg/cm 2 G. The treatment with said ion exchanger causes first the hydrolysis of carboxylic esters to form free carboxylic acids, which inhibit the decomposition of secondary butyl alcohol and the carboxylic esters. Thus, the decomposition gas is distilled to give high-purity isobutylene of more than 99.9%.

Abstract: PURPOSE:To make the whole device compact, and also to exactly detect magnitude of an electric field, by making a polarized light transmit in the direction Z of a Bockels element formed by a Z-cut quartz. CONSTITUTION:A linear polarized light generated from an He-Ne laser 9 is applied in the direction of Z of a Bockels element 11 which has used a Z-cut quartz, directly or through a 1/4 wavelength plate 12. In the Bockels element 11, the polarized surface of the polarized light is rotated in proportion to magnitude of an electric field E, and subsequently, the polarized light transmits an analyzer 4. The analyzer 4 has a polarized surface having prescribed relation to the polarized surface of the polarized light generated by the laser 9, therefore, the quantity of transmission light of the analyzer 4 is varied in accordance with a rotation angle of the polarized light. This quantity of transmission light is detected by a detecting part, and the electric field E is detected. As a result, a variation due to a temperature of the polarized surface becomes about zero, and magnitude of the electric field is detected exactly.

Abstract: PURPOSE:To maintain soundness even if a negative power supply circuit fails by providing a contact for backup in parallel with an abnormality detection relay which is turned on if the negative power supply fails and then providing a backup power supply which is connected to it. CONSTITUTION:For example, when an input voltage in a negative power supply circuit is equal to or less than a specified % of a rated value or is lost, a coil part 21a of an abnormality detection relay 21 is not excited, a contact 21b for detecting abnormality is closed, and then a contact 21c for backup is switched to a passive power supply 23. A circuit reaching the grounding through an alarm display lamp 22b from a reference power supply 22a is formed by switching the contact 21b and then the lamp 22b lights up, thus reporting a failure. When the contact 21c is switched, the terminal voltage of a resistor 23a is supplied to each part by a circuit where the input voltage is divided by the resistor 23a and a constant-voltage diode 23c in the negative power supply circuit. Since the terminal voltage can be controlled stably by the diode 23c, the faulty negative power supply can be backed up.

IPC: G06F13/16
Filed: 1984-05-09
Abstract: PURPOSE:To extend an I/O area by adding the identification bit, which discriminates access to an external bus or access to an internal bus, to address information. CONSTITUTION:If a CPU11 tries to access an external I/O23 connected to the external bus when an output (i) of a bus setting part 18 is ''0'', the identification bit in address information goes to ''1'', and the area of a bank 0 out of an external bus area D is regarded as an area C of the CPU11. When the identification bit is ''1'', an internal I/O decoder 13 does not output an I/O address coincidence signal (a) because address information outputted from the CPU11 indicates the access to the external bus. An external bus access signal (h) is outputted from an external bus access detecting circuit 16.
