Title: Picture processor
Inventor: YUI MITSURU
IPC: H04N9/75
Filed: 1988-03-08
Abstract: PURPOSE:To protect a privacy and practically effectively use by comparing a composite picture with the background picture of a memory, discriminating a background part from an object part and substituting the background part by a fixed pattern. CONSTITUTION:Initially, only the background is image picked up by a camera and stored in the memory 1. Then, the object part of a human being or the like is overlapped on the background to pickup the image of the composite picture and store in the memory 1. This composite picture and the background picture are read from the memory 1, the picture element data of both the pictures are compared in a comparing and deciding circuit 2 to decide whether the picture element data of the composite picture is the background part or the object part. A multiplexer circuit 4 substitutes the picture element data of the background part of the picture element data of the composite picture inputted from a terminal 6 according to the decision result of the circuit 2 by the picture element data of the background of the fixed pattern from a background generating circuit 3 to output the picture element data of the synthesized picture from a terminal 7.

Title: Near visual field optical microscope device
Inventor: YANO KYOJI
IPC: G01N37/00
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To obtain optical information depending on the direction of a substance by controlling the directivity of an evanescent field that exists near a small opening. SOLUTION: Linear polarization light existing a light source is introduced into a polarization retention fiber 102 so that the polarization coincides with the polarization direction of the polarization retention fiber 102, enabling the light to reach an opening at the tip of the fiber while being propagated in the optical fiber with the polarization direction being retained. An evanescent field exists at distance that is approximately equal to a wavelength from the opening to the outside. The direction of the electromagnetic field of the evanescent field depends on the polarization direction of light from the optical fiber but does not have any special polarization surface in the optical fiber and the evanescent field is not directional up to now.  However, in this case, light advancing immediately before the opening has a specific polarization surface, and the evanescent field formed near the tip also has directivity depending on it. When a sample 112 exists in the region of the evanescent field, the evanescent field becomes disturbed propagation light and the intensity of the light is detected by a photo detector.

Inventor: HONMA TOSHIO
IPC: G03G15/00
Filed: 1980-04-22
Abstract: PURPOSE:To execute a large number of copies at high speed, and to prevent increase of accidents, by dividing the whole process into the first copying section and the second arranging section, detecting jam separately in the 2 sections, suspending copying operation in the case of jam occurring in the first section, and suspending the whole operation in jamming in the second section. CONSTITUTION:The preceding step ranging from paper feed to image transfer and the subsequent step ranging from copy discharge to sorting and storing on trays use conveyors driven with dependent motors M1, M4, respectively. Jam check pulses T1-T6, T5', T6' produced from counter CNT1, and detection signals J1-J4, JT, JS produced from sensors arranged on necessary points are checked for jam in the 2 steps along the conveing routes. Jam can be discriminated from completion of reception of the sheets in the receiver. When jam occurs in the first step, FF1 is reset by output of one of gates G5-G7 to stop only motor M1, and observation is kept on from that time. In the case of jam in the second step, FF2, and FF1 are both reset to stop both of motors M4, M1.

Title: Method and device for electrophotographically forming colorproof
Inventor: MANFURETSUDO AARU KUENRU
IPC: G03G15/01
Filed: 1981-04-10
Abstract: An electrophotographic color proofing apparatus including a copyboard carrying a color separated positive and capable of being positioned into intimate contact with a charged photoconductive coating of an electrophotographic member. The engaged members are exposed to light, discharging the coating in increments to form a latent electrostatic image thereon. The copyboard is withdrawn and the exposed electrophotographic member rotated 180 degrees facing toward a toning assembly consisting of a row of plural toning units, each carrying a different color toner and arranged in line for linear translation below the exposed electrophotographic member with a selected one toning unit thereof being activated to apply a selected color toner to the latent electrostatic image. The toned member again is revolved 180 degrees. A pre-wet transfer medium in the form of print paper stock is engaged with the toned member for transfer of the toned image, preferably by drawing a roller across said member while employing a simultaneous electrical bias. A full color proof can be obtained by repeating the cycle, activating successive individual toning units of the assembly and using the same sheet of transfer medium. Registry of plural images applied to a single sheet is effected mechanically, as by upstanding pins provided on the support for electrophotographic member and/or the copyboard. Provision is made to clean both the photoconductive surface and the bias plates of the toning units of excess and/or residual toner.

Title: Exposure mask
Inventor: TOOMASU BENJIYAMIN FUOORE
IPC: G03F1/22
Filed: 1992-02-05
Abstract: PURPOSE: To provide an X ray mask substrate in which a highly extensional film is deposited at a recessed part of the substrate in order to reduce strain to be generated during formation of mask substrate effectively. CONSTITUTION: An X ray mask substrate is provided with a square central region 20 etched with a thin highly extensional film and a highly extensional film deposited on the bottom face 14 of a substrate in order to reduce strain in the substrate. The square central region 20 of the substrate is adapted to support an X ray absorbing material 26 during lithography process. Since a highly extensional film of tungsten, for example, is deposited in the recess, bending moment is produced on the opposite side of the substrate during fabrication process of substrate. Thickness of the film layer is proportional to the magnitude of strain to be generated in the substrate. Integrity is attained when a supporting ring 24 is coupled with the substrate at the peripheral region thereof.

Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To allow the user to hear a reproduced sound from a recording medium in an excellent sound volume offering ease of hearing at all times by allowing a volume control means to be adjustment-controlled to decrease a sound volume of a voice signal when a speech is made. SOLUTION: When a control section 12 discriminates a speech state, the control section 12 checks a current reproduction level of a volume controller 8. When the control section 12 discriminates the reproduction level to be a scale 6 or over, the control section 12 gives an instruction of reproduction at the reproduction level of a scale 5 to the volume controller 8. Thus, the reproduction by a reproduction device 7 at an output level more than a required level is not made without manual adjustment of the reproduction sound by the operator on every speech. Thus, leakage of a recording content undesired to be heard by an opposite party making the speech is not caused due to a microphone 2 of a receiver picking up an output from a loud speaker 1 or due to on the occurrence of bypass to a lien from the reproduction means due to fluctuation in a ground level or the like.
