Abstract: PURPOSE:To enable high-speed wobbling (picture element shifting) and to efficiently attain higher resolution by combining a phase modulation optical element having spacings spacings filled with specific liquid crystals and an optically transparent double refractive medium. CONSTITUTION:This optical device consists of a combination of the phase modulation optical element in which with plural pieces of optically transparent base bodies provided with optically electrodes and oriented films in this order are arranged to face each other apart the prescribed spacings on the electrode and oriented film sides, and in which at least one kind of the liquid crystals selected from among a ferroelectric liquid crystal 3, antiferroelectric liquid crystal and smectic liquid crystal exhibiting an electric gradient effect are injected in the spacings, and the optically transparent double refractive medium 4. By this constitution, the phase of light is changed and the plane of polarization is shifted by the phase modulation optical element and further, incident light is selectively refracted by the double refractive medium 4 and, therefore, the discrete pixels are effectively wobbled. The resolution is thus improved and the image quality is improved as well.

Abstract: PURPOSE:To improve the follow-up ability of a pick-up at the time of occurrence of vibration and vibration resistance against the reading of disk recording information. CONSTITUTION:Dampers (15a-15d) sealing high viscosity oil are arranged at positions where the weight per unit part of an upper chassis 12 is heavy and dampers (15a-15d) sealing low viscosity oil are arranged at the position where the weight per unit part is light and supported by a lower chassis 11. The vibration at the time of occurrence of vibration is absorbed by the dampers (15a-15d) and reduced. Also, rolling phenomenon is reduced by the parallel vibration of the upper chassis 12 against the vibrating direction with different amplitude.

Filed: 1988-05-24
Abstract: PURPOSE:To reduce an insertion loss to a half and to enable space saving and cost reduction by efficiently branching and inserting only one wavelength from a composite signal synthesized with light signals of the wavelengths different from each other to the filter. CONSTITUTION:The composite signal of the wavelengths lambda1 and lambda2 different from each other are inputted to the filter from a composite wave input terminal 101 (terminal A).

Filed: 1990-05-15
Abstract: PURPOSE:To eliminate the problem of reliability and the cost by feeding a local oscillator circuit output to each down-converter block through a feeding circuit pattern and eliminating the need for wiring such as a coaxial cable. CONSTITUTION:The antenna is incorporated with plural down-converter blocks 21 each comprising a low noise amplifier 6 and a mixer circuit 7 to decrease a frequency of a reception signal of an antenna element (a) into an intermediate frequency and with a local oscillation circuit 8 supplying a local oscillation signal to the mixer circuit 7 of the down-converter blocks 21.

Abstract: PURPOSE:To control conductivity to load by setting the conductivity of a power control element by external DC control voltage and mounting a gate trigger circuit synchronizing by zero-cross pulses. CONSTITUTION:When phase control voltage EP is inputted, anode terminal voltage VC increases with the rise of the charging voltage of a capacitor 12.

However, when VP voltage functioning as the zero-cross pulses reaches ''H'' at the  time t3 when the comparator 19 is at OFF, the terminal voltage VC starts its  rise at charging time corresponding to phase control voltage EP1. The same operation is repeated successively.

Title: Image input device
Inventor: MAKINO TOMONORI
IPC: H04N5/378
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To compensate a signal even in the case of using a strong light source by controlling drive of a photoelectric conversion means thereby changing the exposure period of the photoelectric conversion means. SOLUTION: In the case of conducting signal compensation, a drive timing of a CCD by the special scan system is switched. A shift pulse signal S21 is made up of a pulse where two periods of a scan A with the same scanning period as the usual scanning and a scan B with a shorter scan period are repeated. Furthermore, a frequency of a clock signal S22 is changed depending on the scan so that the same number of pulse signals is generated between the two periods of scan A and scan B. An output A corresponding to the scan A of a CCD output S23 reaches a saturated point similarly to the case with the usual scan, but the output B corresponding to the scan B does not reach the saturated point. Then the signal is compensated by sampling the output B at that time.

Abstract: PURPOSE:To surely reproduce picture information of characters or the like in a picture frame by automatically controlling the range of image forming area control in accordance with information formed in the picture frame of a microfilm. CONSTITUTION:The edge part of a picture frame F out of the picture recorded on a microfilm M projected to an image receiving body is detected by an optical sensor 50, and it is discriminated whether information is recorded in the vicinity of the boundary of the picture frame F or not. When information is not recorded there, image formation from the edge part of this picture frame F to the inside of a prescribed range is automatically controlled in accordance with signals from control means 62 and 64 by image forming area control means 25, 26, and 52. Therefore, the ground part of the film is not reproduced on a recording paper at all, and image formation up to the position discriminated as the edge part of the picture frame is automatically controlled if information is recorded there. Thus, information in the picture frame is surely reproduced.
