Inventor: TSUCHIDA MICHIRO
IPC: G03B21/00
Filed: 1990-08-20
Abstract: PURPOSE:To enable the bright swing and tilt projection of information of projection materials on a screen without distortion by using all of the light from a light source by setting the optical axis of a convergence system at a necessary swing and tilt angle to the optical axis of a projection system. CONSTITUTION:The light convergence system optical axis 7 is set at a swing and tilt angle theta to the photography system optical axis 6. Therefore, the swing and tilt angle of a converging Fresnel lens 2 to a projection film 3 is set to theta. This angle theta is so set that the marginal light beam 8 of light centering on the light convergence system optical axis 7 matches the projection system optical axis 6. A projection lens 4, the projection film 3, and the screen 5 are arranged at right angles to the projection system optical axis 6, so the information of the projection film 3 is projected on the screen 5 without any distortion. Further, the light convergence system optical axis 7 is set to said swing and tilt angle thetato the projection system optical axis 6, so all of the light from the light source 1 can be used for the projection of the projection film 3.

Title: Lighting system and liquid crystal display device using same
Inventor: ADACHI MASAYA
IPC: G02F1/1335
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To make the light return to a lighting system again after irradiating an object with high efficiency as a reverse polarized light, by causing a reflecting surface of a polarization-maintaining reflector to reflect linearly polarized light as linearly polarized light left as it is, and to reflect circularly polarized light as circularly polarized light in reversed rotational direction, with respect to, at least, vertically incoming light. SOLUTION: A reflecting surface 104r of a polarization-maintaining reflector 104 reflects the light returning from the side of a liquid crystal panel 114 as the polarized state of the light is maintained, that is, linearly polarized light is reflected as it is, and circularly polarized light is reflected as circularly polarized light in reversed rotational direction, with respect to, at least, vertically incoming light. The light 203 returned to a just-under backlight device 106 goes to the polarization-maintaining reflector 104, then is reflected by the reflecting surface 104r constituting most of the polarization-maintaining reflector 104, and again radiated to the liquid crystal panel 114.  Because the reflecting surface 104r has not much effect on the state of polarization, the light 203 again radiated maintains the initial state of polarization and contributes to display substantially without being absorbed by a polarizing plate 111.

Abstract: PURPOSE:To make the apparatus convenient to carry with a smaller size, by winding one end of a sample tape as object to be inspected on a sample winding roller to determine a peeling force from the current required torque. CONSTITUTION:A winding roller 1 is idled with no load beforehand and a torque is detected with a strain gauge 11 corresponding to the position of rotation of the gauge and a torque detection signal is stored into a memory.

Filed: 1988-09-02
Abstract: PURPOSE:To enable the whole inductance device to be manufactured in simple structure and high torque in a miniaturized size by a method wherein said device is provided with a coil, a core and an ultrasonic motor mechanism to drive said coil and/or core. CONSTITUTION:An inductance device A is composed of a core 1 and a coil 2 wound around this core 1. The core 1 is pressure-fixed on a stator 3 in ultrasonic ellipsoidal oscillation while the core 1 is driven to be reciprocated by the ultrasonic ellipsoidal oscillation of the stator 3 through the intermediary of the frictional force, (the core 1 is working as a rotor of an ultrasonic motor, however, the term 'rotor' not necessarily means 'to rotate' but means 'to reciprocate'). Consequently, when the stator 3 is ultrasonic ellipsoidally oscillated by the ultrasonic oscillation from an ultrasonic oscillator, the core 1 in the variable coil 2 is reciprocated on the stator 3 of the ultrasonic motor to be reciprocated in the coil 2 resultantly changing the inductance.

Filed: 1992-07-24
Abstract: PURPOSE:To improve the deficient information on the chroma signal in an RGB conversion state of the first pixel. CONSTITUTION:The analog video signal undergoes the A/D conversion and then the Y/C separation and the Y/C separated data are converted into the R, G and B data through an RGB matrix by an RGB conversion method for the digital video signal.

Title: Developing method of electric latent image
Inventor: ANZAI MASAYASU
IPC: G03G13/09
Filed: 1984-10-19
Abstract: PURPOSE:To develop a fine picture highly efficiently by forming a fine and uniform magnetic brush as a magnetic carrier and using high-purity fine iron powder consisting of 10-30mum grains which can reduce the electric resistance of a developer as high toner concentration developer. CONSTITUTION:Pure iron having 98% or more purity is used as a carrier, its average grain size is set 10-30mum to make the carrier fine grains and the ratio of the carrier to toner is set to 100 to 20 or more in weight ratio by a magnetic brush in a developing part to increase the toner concentration. If the average grain size is increased more than 40mum, the magnetic brush is made rough, so that fine picture quality can not be obtained and the life of the carrier is reduced because of much adhesion of spent toner. When the average grain size is 10mum or less, fluidity as a developer is reduced and such fine grain size is improper to the developer. Since the toner concentration is increased so as to be >=20 per 100 of carrier, the property of the magnetic brush is made fine and soft.
