Title: Optical reproducing device
Inventor: OOKI YUTAKA
IPC: G11B7/005
Filed: 1980-07-29
Abstract: PURPOSE:To facilitate focus adjustment by providing a focus servo circuit with a means of adjusting the distance between a disk and an objective lens finely and by making the fine adjustment while monitoring the level of a reproduced signal. CONSTITUTION:A signal detected by a photodetector 6 is amplified by a head amplifier 7 and an amplifier 13, and a DC voltage which corresponds to the level of the reproduced signal is supplied from a rectifying circuit 14 to a monitoring device 12. As this monitoring device 12, a display device, etc., such as a voltmeter,  performing step display corresponding to the lighting states of light emitting diodes  is used. Even if the influence of secular change, etc., shifts the optical axis of a laser beam and temperature fluctuations, etc., vary the characteristics of circuit elements, focusing circuit is adjusted without using a special measuring instrument, while the monitoring device 12 is viewed, so that the level of the reproduced signal reaches its peak or exceeds a prescribed level.

IPC: G06T19/00
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To enable more natural three-dimensional(3D) view without overlapping preceding and following display images in the view from an observer by synthesizing a mask image with respective 2D images except a front picture, erasing the display information at the hidden sections of respective 2D images except the front picture, and displaying it on a 2D display device.

Relating to the synthesizer 126, for example, the mask images generated by the mask image generators 120-122 are overlapped on a 2D image 119 displayed on a 2D display device 103. Next, the section to be hidden by images 115-117 displayed from 2D display devices 101-103 is erased by the mask images or its transmission factor is changed. Thus, the section hidden by the images 115-117 is not watched through.

IPC: H04B10/077
Filed: 1991-05-10
Abstract: PURPOSE:To provide the optical communication equipment employing a wavelength multiplexer communication line used for communication of a terminal equipment in which a wavelength used for transmission and reception is allocated in response to a dial request of the terminal equipment. CONSTITUTION:When a terminal equipment 1-1 uses a control wavelength for a dial request, a wavelength controller 8 selects a wavelength used by the terminal equipment among wavelengths not yet in use on a wavelength multiplexer communication line 6 and informs the wavelength to the terminal equipment 1-1 by using the control wavelength. The terminal equipment 1-1 adjusts the wavelength of a transmission and a reception circuit to the noticed wavelength for the communication. Since the wavelength of the wavelength multiplexer communication line is managed by the wavelength controller and a wavelength is allocated to the terminal equipment making a dialing request in this way, the wavelength is effectively utilized. Moreover, the extension of terminal equipments is facilitated.

IPC: C23F4/04
Filed: 1987-04-27
Abstract: PURPOSE:To simplify remove the desired part of a thin film formed on a substrate with no accumulation of residue by holding the substrate in a soln. which is not chemically reactive with the thin film and by radiating pulsating laser light on the desired part of the thin film. CONSTITUTION:Al is vapor-deposited on SiO2 formed on an Si substrate by thermal oxidation and polyimide is deposited on the vapor-deposited Al. The substrate 5 is held at a prescribed position in a processing cell 3 and water 11 is introduced into the cell 3 from a soln. feeding unit 2 so that the surface of the water is made higher than the surface of a thin film on the substrate by about 100mu.

IPC: G03G5/02
Filed: 1981-07-08
Abstract: PURPOSE:To provide a device whicn can discriminate information abnormality by forming the surface potential of the polarity reversed from that of the 1st surface potential on a photoreceptor, and exposing the same at the quantity of light of ternary levels. CONSTITUTION:An electrostatic charger 2 and a lamp 3 are turned on simultaneously to charge an insulation layer 1c negatively. Since a photoconductive layer 1b is conducted for the purpose of full surface exposure, the positive charge from a conductive substrate is injected into the layer 1b and the positive charge distributes at the interface between the layer 1c and the layer 1b. The insulation layer is applied with the secondary charging of the polarity reversed from that of the primary charging by way of an electrostatic charger 4 so that the surface potential is inverted from negative potential to positive potential. A three-layered photoreceptor 1 of such a state is exposed by the information wherein the quantity of light has 3 stages of levels, whereby the positive and negative electrostatic latent images corresponding to black and red information are formed.

Abstract: PURPOSE:To surely convey a sheet by operating a spring which can transmit lift operation of a lift member to a sheet conveying means, between the lift member and the sheet conveying means. CONSTITUTION:When a cam 74 is turned in the clockwise direction, one end side of an intermediate lever 81 is gradually lifted and moved upward by a circular arc surface 74a.
