Title: Image formation method for optical recording medium display
Inventor: MAEDA SHUICHI
IPC: G11B7/26
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To make a high definition display formable without damaging a recording medium by employing a transparent resin as a substrate and forming a display such as character, figure, pattern and the like on an outermost layer of an optical recording medium by jetting thereon a sublimative gas of a sublimative pigment. SOLUTION: As a transparent substrate, for example, a polycarbonate resin, an acrylic resin, an polystyrene resin, a polyvinyl chloride resin, and the like, is used. The polycarbonate resin is preferable because it has a higher light transmittance and a smaller optical anisotropy. A material of a recording layer is not limited to a specific one. As an inorganic material, a rare-earth type transition metal alloy such as TbFeCo or DyFeCo and a chalcogen type alloy such as GeTe or GeSbTe can be used, while as an organic material, an organic pigment, for example, a metal-including azo-type pigment, is mainly preferable because of its excellent endurability and anti-light capability. A non-ionic type sublimative pigment, e.g. azo-type, anthrachinone-type, nitro-type, styryl-type, naphthochinone-type, and the like is used, and a sublimative gas is jetted to form a display.

IPC: H04N5/74
Filed: 1992-10-19
Abstract: PURPOSE:To provide a display image pickup device in which visual lines of conversation persons are made coincident through an excellent video image and a display space sensing the conversation at the same location is realized. CONSTITUTION:A projector 2 is arranged behind a screen 1 in an oblique direction so as to arrange a video camera 2 on the rear side of the screen 1 vertically, thereby eliminating the disturbance of optical paths of projection video images and pickup images caused through the mutual arrangement. In this case, an inverse trapezoidal distortion correction circuit 4 corrects reversely in advance the trapezoidal distortion of a projected video image to a screen 1 from the oblique back direction so as to display a correct video image. Thus, the optical axis of the projection and that of image pickup are made coincident on the face of the screen 1 to make the visual lines of conversation persons 5 coincident with each other and the light of a light source or the like of the projector is not directly invaded to the conversation person 5 in the front face. Furthermore, a mask 6 is provided between the projector 2 and the screen 1, the display of the light source or the like is prevented by shielding light by the image pickup period to obtain a clean image pickup image.

Abstract: PURPOSE: To automatically inspect the radius of curvature and the distortion of a road reflecting mirror or the like by obtaining objective values without only depending on the eyes of a person by placing a convex reflective subject on a placing table, deterimining the central position by means of a position calibrating limiter for irradiating laser beams, and by measuring the reflected rays. CONSTITUTION: A stage forward and backing mechanism 3 is drawn out simultaneously with a subject placing table 2, and a subject 1 is placed nearly at the center of this placing table 2, and then the stage forwarding/backing mechanism 3 is gradually pushed in. In the process the stage is pushed in, the centering of the subject 1 in the right and left direction is carried out by subject position calibrating limiters 5, 5'. The forward and backing mechanism 3 is stopped at a predetermined given point, and the subject 1 is fitted in the turning center of the placing table 2. A measuring head 10 is moved parallel in the right and left direction by a slider 13 through a pulse motor 12 and a timing belt 11.  A fine laser beam from a laser diode 6 enters a semi-transparent prism 7, and irradiates the surface of the subject 1, and then is reflected therefrom and reaches a position signal generator 8 through the prism 7. The radius of curvature is obtained by the calculation from the positional signal of the generator 8.

Title: Image sensor control method for optical device
Inventor: HIDESHIMA TAKAHIRO
IPC: H04N1/04
Filed: 1986-11-27
Abstract: PURPOSE:To attain the read of picture information with high accuracy by using a time between two transfer pulses before and after a synchronizing signal representing a luminous change period among transfer pulses outputted at every period synchronously with the luminous quantity change period of a light source lamp and commanded by a control means as the effective storage time of an image sensor. CONSTITUTION:A control means 48 adopts only the information transferred to a transfer section by a transfer pulse D next to a synchronizing signal (b) as an output signal (f) representing the effective picture information and throws away the output signal (f) by other transfer pulse (d) as an ineffective output signal. That is, only the storage time (m) is used as the effective storage time and the picture information in between is used as the output signal (f). A control means 48 uses the output signal (f) to control the exposure. For example, when the output signal (f) to each picture element exceeds the preset maximum value, the effective storage time (m) is reduced by revising the period (l) set by the periodic signal (c). Thus. the blooming of the line sensor 56 is prevented.

Abstract: PROBLEM TO BE SOLVED: To keep condensed water from being frozen even under a high frequency operation of a compressor by restricting spraying condition with a rise in moisture within a room to be air conditioned after the restarting of the compressor during the cooling operation. SOLUTION: A room fan 102a and a damper unit 2 are controlled so that air blown from a room unit 102 is blown outside a room 101 to be air conditioned for a fixed time length via an exhaust duct 1 when a compressor is stopped because of the turning OFF of a thermostat or the stoppage of operation and condensed water of a room heat exchanger 102b is discharged outside the chamber to be air conditioned. This enables the removal of the condensed water of the room heat exchanger after the restarting of the operation of the compressor to keep moisture attributed to re-evaporation from being released into the room to be air conditioned thereby eliminating a rise in the moisture within the room.

In this case, when a slit capable of passing through the conjugate point of the area where the foreign matter 36 is placed is provided, only the reflected beam from the foreign matter 36 is incident on a photodetector 34. The laser beam 18 is scanned in the direction vertical to the surface of space and the slit is also formed in an elongated shape in the direction vertical to the surface of the space in order to correspond to the scanning of the laser beam. By this constitution, the foreign matter on the substrate can be inspected without being affected by the circuit pattern formed on the substrate.
