Inventor: KOMURA SHUJI
IPC: B41M3/12
Filed: 1987-11-30
Abstract: PURPOSE:To prevent a color picture image to be obtd. from being impaired by arranging a toner picture image of a copy to be transferred simply as a color picture image to another transfer material. CONSTITUTION:A copy having a white or transparent toner picture image 40 is obtd. on a heat resistant resin sheet coated with silicone oil baked thereon, and a base material for the transfer sheet having a resin layer contg. a colorant dispersed therein is superposed on the heat resistant resin film interposing a wax layer so as to face the colorant dispersing resin layer oppositely to a surface carrying a toner picture image 40 of the copy, and the resin layer is heated. Then, a color transfer sheet is produced by removing the colorant dispersing resin layer 23 corresponding to a nonpicture image part of the base material 30 for the transfer sheet carrying the obtd. toner picture image after transferring the toner picture image 40 to the base material for the transfer sheet. Since a surface 40 of a white toner picture image is coated with a resin layer 23 contg. a colored colorant dispersed therein, the hue of the formed color picture image is not influenced by the hue of a ground toner layer, and a desired color picture image is obtd. without being impaired in its distinctness.

Title: Image forming device and cleaning member exchanging method
Inventor: TSUKAMURA SHINICHI
IPC: G03G21/10
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To prevent a period when image forming operation can be performed from being shortened according to time required for exchanging a cleaning member by controlling a cleaning member exchanging means so that the cleaning member may be exchanged in the case of deciding that the cleaning member must be exchanged and the image forming operation can be executed. SOLUTION: When a blade exchanging propriety decision circuit 13b decides that a blade 18 must be exchanged and a status signal is turned on, a master control circuit 13c turns on a toner adhesion signal. Simultaneously, a rotation stopping signal is turned on, and a photoreceptor starts idle rotation and is decelerated. Toner is tinged with minus charge because it is stirred inside a developing unit, and the toner adheres to the surface of the photoreceptor even when the photoreceptor does not have minus charge.  When the standstill of the photoreceptor is detected by an encoder, a blade exchanging signal is turned on, a supporting shaft moving means 21 shifts a shaft holder 22 from a blade press-contacting position to a blade exchanging position, and a supporting shaft rotating means 20 is turned on, then a blade supporting shaft 19 is rotated so as to exchange the blade for a new blade 18.

Title: Electrolysis method
Inventor: EZAWA NOBUYASU
IPC: C25B1/16
Filed: 1987-11-30
Abstract: PURPOSE:To avoid the consumption of a large quantity of energy required to generate gas and to enable an energy-saving electrolytic reaction by feeding hydrogen generated on the cathode to the anode and transferring an anode reaction into an oxidation reaction of hydrogen. CONSTITUTION:Gaseous hydrogen generated on the cathode in a cell by an electrolytic reaction is fed to the anode through a communicating pipe without discharging from the cell. The hydrogen is oxidized to hydrogen ions on the anode and the hydrogen ions form an acid with anions present in the anode chamber. In this case when gaseous hydrogen is not fed to the anode chamber, the anions are oxidized and converted into corresponding gas which is discharged from the cell. In case of org. acid ions, org. molecules are oxidized and broken. The quantity of energy required to generate hydrogen ions by the oxidation of gaseous hydrogen is much smaller than that required to generate gas by the oxidation of chlorine ions, etc., so the quantity of electric energy required to produce alkali is considerably reduced and economical operation can be carried out.

Title: Optical integrated circuit
Inventor: SHINDO HIDEHIKO
IPC: G02B6/122
Filed: 1987-11-30
Abstract: PURPOSE:To remove the unnecessary light in a slab waveguide and to improve optical performance by forming a complex dielectric material which absorbs the light scattered in the slab waveguide into a laminated structure. CONSTITUTION:The complex dielectric material 5 which absorbs the light scattered in the slab waveguide 2 is formed into the laminated structure on the region except the region for propagating light of the slab waveguide 2. Namely, the complex dielectric material (material having a complex dielectric constant) 5 consisting of a metal or conductive ceramics, etc., is formed into the laminated structure on the region which is not required for propagation of the light contg. signals of the slab waveguide 2. Since this complex dielectric material has the high complex dielectric constant (about -40--100dB/cm), the material effectively absorbs the unnecessary light and is capable of removing the unnecessary light from the inside of the waveguide. The optical performance of an optical integrated circuit is thereby improved.

Abstract: PURPOSE:To eliminate an uneven brightness in the lateral direction and to increase the visual field in the horizontal direction in a simple constitution by providing the longitudinal directions of light sources and the side edge directions where reflection boards are contacted to the displays of the display units, in the lateral direction. CONSTITUTION:Plural display units 20 using a PLZT are arranged by making the side edge direction where reflection boards 16 are contacted to displays 12 coincident in the lateral direction. And fluorescent lamps 24 form the common light source of the units 12. As a result, the side edges of the reflection boards 16 are not positioned to the borders of the displays 12 of the units 20, and thereby, the side edges of the reflection boards 16 make no cause to reduce the brightness of the displays 12 when the displays 12 are observed from the oblique direction in the horizontal plane, and the brightness in the lateral direction is made even. Consequently, even though the displays 12 are observed form the oblique direction in the horizontal plane, no parallel slit of the brightness is generated, and no uneven brightness is generated. As a result, the visual field angle in the horizontal direction can be widened.

Abstract: PURPOSE:To control attenuation of building vibration efficiently and in a short time by deciding a value of electric current which is supplied to a magnetic coil for swinging a pendulum so that the vibration is attenuated based on vector information of an acceleration which has been detected and computed. CONSTITUTION:When vibration is applied to a building, acceleration of the vibration of a floor surface 1 is detected by an acceleration sensor 6. Based on information of this acceleration, an acceleration vector computing unit 7 computes the acceleration vector of the vibration of the floor surface 1 and informs a magnetic coil control unit 8 of the computed acceleration vector. The magnetic coil control unit 8 selects a couple of magnetic coils 5 and 5 which generates a magnetic field based on the direction of vector out from the content of the acceeration vector information in, order to make a weight 4 of a single pendulum 3 produce such an acceleration vector motion that attenuates the vibration of the floor surface 1. The magnetic coil control unit 8 also decides an electric current value according to the strength of the magnetic field generated on the basis of the value of vector, and supplies this current to the selected couple of magnetic coils 5 and 5. This makes the weight 4 of the single pendulum to swing, resulting in attenuation of the vibration.
