Title: Diaphragm device of liquid crystal
Inventor: NISHIOKA KIMIHIKO
IPC: G02F1/133
Filed: 1985-02-01
Abstract: PURPOSE:To improve the utilizing efficiency of light, by forming at least two layers of a biaxial substance which can variably electrically control the value of refractive index or main-axial direction of refractive index. CONSTITUTION:One transparent member is formed to have a convexly curved surface, such as spherical surface, etc., and the other transparent member is formed to have a concavely curved surface which houses the convexly curved surface. Transparent electrodes 51 and 52 are respectively formed on the opposing curved surfaces. Then transparent electrode films 54 and 54 are put on the electrodes 51 and 52 with spacers 53 and 53 between them, respectively, and thus, cells are formed along the curved surfaces. After the cells are formed in such a way, liquid crystals 56 and 56 are enclosed in the cells. It is arranged that AC voltages of AC power sources 21 and 22 can be applied variably across the transparent electrodes 51 and 52 through interlocked variable resistances 57 and 57 by means of interlocked switches S1 and S2, respectively. Since the incident angle continuously changes, areas of sections where a refracted condition is set and where a totally-reflected condition is set can be changed concentrically in accordance with the applied AC voltages and the light quantity control changeable width can be made very wide.

Title: Pwm signal generator
Inventor: INTO JUNICHI
IPC: H02M7/48
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To provide a PWM signal generator free from malfunctioning at the starting time of the generation operation of a PWM signal, without using a superfluous circuit for setting operation. SOLUTION: A counter 26 counts a specified clock signal. A comparator 27 compares corresponding individual bits of the counter 26 and a register means concerning each register means, and outputs a coincidence signal when the values of individual bits coincide all. Each time a coincidence signal is outputted by the comparator 27, an output inverting means inverts the state of the output signal corresponding to a register means being concerned in comparison. And a setting means sets a required data calculated by an adder in the register means being concerned in comparison in accordance with on-width or off-width data.  By initialization, the value of the register means being concerned in comparison is initialized to a certain specific value, and a coincidence signal to be generated by the comparator 27 first, at the starting time of PWM signal generating operation after the initialization, is produced at the initial value of the register means being concerned in comparison.

Title: Printing-density variable dot printer
Inventor: YAGETA KOICHI
IPC: B41J19/96
Filed: 1989-01-27
Abstract: PURPOSE:To change dot density in the longitudinal direction easily, and to increase printing speed when dot density is reduced by separating and setting the distances of the paper-feed direction among each adjacent dot head in response to the smallest printing density of printing density and altering paper- feed pitches after the printing of N dot lines in response to the printing density. CONSTITUTION:The number of the dot lines of paper-feed is controlled properly in response to printing density and printing density can be varied, and printing speed can be accelerated when printing density is decreased. When printing density is changed, a platen must be improved because the quality of printing largely depends upon the difference of the diameters of printing dots. A soft elastic body 5, a hard elastic body 6 and a metallic section 7 are mounted onto the surface of a mandrel 4 in the platen 3, and the platen 3 is used properly in response to each printing density. Since the quality of printing is deteriorated when the diameters of printing dots are increased in response to the printing density on printing at low density, the section of the soft elastic body 5 is employed. The metallic section 7 not deformed is used on printing at high density, and the hard elastic body 6 is employed on printing at intermediate printing density.

Title: Liquid crystal display element and its production
Inventor: YAMAZOE HIROSHI
IPC: C08L39/06
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display element having the volume occupying rate of liquid crystal drops as high as about 80%.

Title: Integration circuit
Inventor: UCHIDA YOSHITAKA
IPC: G06G7/184
Filed: 1988-01-28
Abstract: PURPOSE:To enable high speed integration operation even if the frequency component of an input signal is high by containing a voltage current conversion circuit and a capacitor connected in parallel with an output. CONSTITUTION:Because the collector current I2 of a transistor (TR)Q2 is in the relation of I2proportional Vin, and the TR2 and Q6 constitute a current mirror, the increase/decrease of I2 appears while being proportional to I5. Now, when respective resistors are set so as to satisfy the relation of I5=I6 at the time that the input signal is 0, because the balance of I5 and I6 is broken, and a difference current flowing in the capacitor is generated, integration becomes possible. Output impedance is very high because the TRs Q6 and Q7 are of collector output of base grounding, and the decrease of an integrated value can be suppressed. Because this circuit is not of circuit constitution using feedback, the integration of a high frequency signal is easy, and the integration of the output of a correlator which is high frequency becomes possible.

Abstract: PURPOSE: To obtain constant voltage circuit suitable for voltage reduction and stabilization, by supplying power supply voltage between the gate and drain of depletion type MOSFET (DMOST) and picking up the output between the gate and source.  
     CONSTITUTION: The gate 2 of N channel DMOST1 is connected to load power supply, drain 3 is to the positive power supply VDD, and the source 5 is to the load 4. When the power supply voltage VDD increases and the drain current ID is going to increase, the gate potential VG is lowered to the source potential VS, the increase in the current ID is restricted, and the voltage VL fed to the load 4 is not increased. If the voltage is decreased, the inverse operation is made and the voltage VL of the load 4 is not lowered. When the impedance of the load 4 is increased, the voltage VL is going to increase, but the voltage VG is lowered to the potential VS, the current ID is reduced and the increase in the voltage VL is restricted. When the load impedance is lowered, the inverse operation is made and the lowering in the voltage VL is restricted. When the load is an E-MOS, suitable regulated voltage can be given.

Abstract: PROBLEM TO BE SOLVED: To always form an excellent image by controlling an image forming position decided according to synchronizing timing between a toner image formed on an image carrier in accordance with the thickness of transfer material and the transfer material carrier to the surface of the image carrier. SOLUTION: When a copying job is started, a system control part 41 discriminates whether paper is fed from a manual feeding tray or a paper feeding tray. When judged that the paper has been fed from the manual feeding tray, the control part 41 discriminates, based on the detected result by a thickness detection sensor 36 whether or not transfer paper fed from the manual feeding tray is cardboard. In the case of judging that the transfer paper is not the cardboard, the write starting position of an ROS(raster output scanner) is adjusted by a normal shift amount and the image is adjusted so as to output the image written by the ROS. In the case of judging that the transfer paper is the cardboard, the write starting position of the ROS is adjusted by a value obtained by adding the adjusting amount at the time when the transfer paper is the cardboard to the normal shift amount.
