Abstract: PURPOSE:To realize highly fine image display with a small size and small thickness by subjecting an electrophoretic image display element provided with an electric charge receptor to writing by scanning of an ion source and forming an electric field between the charge receptor and a transparent electrode. CONSTITUTION:A negative ion beam is projected over the entire surface of the electric charge receptor 23 by an ion generator 1 and the electric charge 27 is generated in the surface of the receptor 23 as well. White TiO2 particles migrate to the receptor 23 side when the voltage impressed to an electrophoretic liquid suspension 25 layer by said electric field increases to the voltage larger than the threshold voltage at which pigment particles 26 in the liquid start migrating. Said particles are then fixed to the surface of the receptor and a 1st stable state is generated. A positive ion beam is then projected imagewise to the receptor 23 by the generator 1. The positive charge is imparted imagewise to the receptor 23 by such projection and the electric field in the direction different from the previous electric field direction is generated in said part. The white TiO2 particles migrate to the transparent electrode 22 side and stick imagewise on the surface thereof when the voltage exceeds the threshold. The 2nd stable state is thus obtd.

Title: Semiconductor light emitting module
Inventor: KATO TAKASHI
IPC: H01S5/06
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To effectively prevent the occurrence of mode hopping by changing a stress to be applied to a diffraction grating to bring a diffraction wavelength of the grating substantially into matching with one of longitudinal mode resonating wavelengths of a laser resonator. SOLUTION: A fiber grating(FG) 5a formed near an end of an optical fiber 5 is disposed in a ferrule 4 to constitute a resonator, together with a high reflectivity film 3a of a light emitting element 3. When the fiber 5 is drawn from a rear end side of the ferrule 4 to operate a tensile stress to the fiber 5 while observing a spectrum of a light emitted from the rear end side of the fiber 5, a diffraction wavelength of the FG changes according to the magnitude of the applied stress, and hence one of longitudinal mode oscillation wavelengths can be substantially brought into matching with the diffraction wavelength by applying a suitable tension to the fiber. Accordingly, stable oscillation without the generation of mode hopping can be performed.

Title: Deflecting yoke
Inventor: KUWABARA YASUNAGA
IPC: H01J29/76
Filed: 1990-07-26
Abstract: PURPOSE:To eliminate color deflection by coma aberration and restrict deformation by winding cable by changing the cut length of cable grooves to set the effective length of a coil longer as it gets further from the start of coiling to the end of coiling. CONSTITUTION:Cable grooves 1-3 for winding a cable are provided, where the groove 1 is on the starting side of winding, and the groove 3 is on the ending side. Using a slit bobbin formed in this constitution, a cable is wound to be a deflecting coil. In this case, for a magnetic field on the side of an electron gun of a television picture tube, the effective length of the coil is set longer on the starting side of winding than the effective length of the coil on the ending side of winding as in a normal deflecting yoke. This means that, the effective lengths of the coil become that of the groove 1>2>3, where the part of the groove 3 for forming a pincushion magnetic field becomes shorter than that of the grooves 1, 2. The generation of color deflection in a screen due to occurrence of coma aberration can thus be eliminated, and deformation of the slit bobbin is less likely to occur with relation to the strength structurally.

Filed: 1984-09-26
Abstract: PURPOSE:To allow clogging hard to generate by collecting cotton dust causing the damage of an ionization part and the generation of abnormal noise with high efficiency, by using a pre-filter having conductivity and reduced in gas permeating resistance. CONSTITUTION:Dust-containing air is sucked in an air passage from a suction port 2 by a fan 4 and passed through a filter body 10 to reach an ionization part. An electrostatic field of 0.2-1kV/mm is formed between the filter body 10 and ionization electrodes 6 and an ion current of several ten-several hundred microampere flows from the ionization electrodes 6 toward the filter body 10 and, therefore, cotton dust having an especially large specific area in dust- containing air passing through the filter body 10 receives electrostatic force directly or after charging to be attracted and collected by the metal foil surface thereof. As a result, it is prevented that dust is adhered to the surfaces of the ionization electrodes 6 or penetrated between acceleration electrodes 8 and opposed electrodes 9 to damage the electrodes 6 or abnormal noise is generated.

Abstract: PURPOSE:To generate an optical signal of multiplexed wavelength at a high speed. CONSTITUTION:A pulse generating section 12 generates master pulse optical signals lambda1-lambdaI of a same wavelength repetitively at a prescribed time interval T in the order of lambda1, lambda2,..., lambdaI, lambda1,.... Then the section 12 inputs the lights lambda1-lambdaI time-sequentially to a 1X4 branch 14, which generates slave pulse lights lambdai1-lambdai4 of the same wavelength from one master pulse light lambdai (i=1, 2,..., I). The lights lambdai1-lambdai4 are subjected to intensity modulation by each on/off optical switch 22 and a binary optical signal is generated. Then a delay optical fiber 24 is used to apply delay processing to the lights lambdai1-lambdai4 so that the output time of the lights lambdai1-lambdai4 is deviated for a time interval tau=T/4. The lights lambdai1-lambdai4 subjected to delay processing and intensity modulation are synthesized by a 4X1 branch 20 and a high speed optical signal is generated.
