IPC: G02B6/24
Filed: 1981-06-01
Abstract: PURPOSE:To fix optical fibers on the optimum coupling positions by fixing the optical fibers on optical fiber fixing grooves cut on an optical fiber fixing board through an optical fiber fixing material which reduces its viscosity at a high temperature and is hardened at room temperature. CONSTITUTION:An optical fiber fixing board 1 on which grooves are formed at the same pitch as that of an optical element array is put on a hot plate heated to <=100 deg.C and a lump of ''Diffuro oil  '' 2 for example is put on the optical fiber fixing board to fill the grooves with the oil. Subsequently, the temperature of the hot plate is reduced to 50-65 deg.C and protective resin coats 4 are removed from respective leading end parts before the ''Diffuro oil  '' 2 is hardened to set and bury the fibers 3 in the grooves. The surface of the fiber- buried fixing board is pressed by a plane plate or a grooved plate with the same pitch as that of the fibers 3 to put each fiber 3 on the optimum position for coupling with each optical element and then the adherent is hardened.

Title: Optical system of information reader
Inventor: NAKADA YASUO
IPC: G02B27/18
Filed: 1985-04-19
Abstract: PURPOSE:To reduce the influence of temperature variation upon an image forming element by charging liquid which has large specific gravity among respective elements which constitute an optical image formation system. CONSTITUTION:The optical image formation system consisting of three groups of lens arrays 1-3 made of plastic include the arrays 1-3 at specific intervals, and optical axes of lenses constituting the arrays are made coincident with optical axes of lenses constituting other arrays. An information reader forms an original image of an original surface 0 on a photodetection surface 4 through the optical image formation system and reads it. The arrays 1-3 are fixed at specific mutual intervals so that the optical axes of the lenses are made coincident by a sealing plate 6 parallel to the optical axes. Further, the liquid 7 which has large specific heat is charged among the arrays 1-3 sealed by the sealing plate 6. This constitution increases the heat capacity of the whole optical image formation system, so the generation of the temperature distribution of the optical image formation system due to the heat generation of a light source is suppressed to hold the whole optical image formation system at nearly constant temperature, thereby obtaining performance as designed.

Title: Image reducing method and multi-screen generating method
Inventor: TSUKAMOTO AKITO
IPC: G06T3/40
Filed: 1991-03-25
Abstract: PURPOSE:To process image reduction and multi-picture generation at high speed with simple configuration by executing an inverse orthogonal transform processing only to a coefficient up to a dimension decided in advance corresponding to the rate of image reduction. CONSTITUTION:Digital image signals are orthogonally transformed by an orthogonal/ inverse orthogonal transform circuit 6 and recorded in a recording medium 3, these orthogonally transformed data are read for the unit of a block in the case of reproduction and similarly inversely orthogonally transformed by the orthogonal/inverse orthogonal transform circuit 6, afterwards, picture elements are thinned, the image is reduced and a multi-picture or the like is generated. Corresponding to the rate of image reduction in that case, the dimension to execute the inverse orthogonal transform is limited. The plural images reduced in this way are simultaneously projected on one screen, and the multi-picture is obtained. Namely, since the dimension of the coefficient to be calculated by the inverse orthogonal transformation is set corresponding to the rate of image reduction, not only processing time for the inverse orthogonal transformation is considerably shortened but also return distortion caused by the thinning of picture elements can be reduced without any horizontal/vertical filter or excess frame memory.

Title: Method and device for inspecting pinhole in sealed package body
Inventor: SUDA YUSUKE
IPC: G01M3/38
Filed: 1989-04-03
Abstract: PURPOSE:To easily inspect whether or not the sealed package body has a pinhole with efficiency by irradiating the entire surface of the sealed package body with scattered light from one side of the sealed package body and inspecting whether or not there is leaking light from the other side of the sealed package body as 1st invention.

Title: Optical disk recording device
Inventor: AOSHIMA SHINJI
IPC: G11B7/125
Filed: 1993-03-19
Abstract: PURPOSE:To prevent the deterioration, etc., of the SN ratio of a wobble signal when the magnification of a recording speed is varied. CONSTITUTION:A setting means 28 for the magnification of a recording speed sets the magnification of a recording speed by means of the manipulation of an operator, etc. An irradiating time control means 26 modulates an input FEM signal by means of an (n-1) strategy, etc., and controls the irradiation time of a recording laser beam 11. A laser power control means 25 changes a pit power in a pit period according to the magnification of a recording speed. Namely, since the thermal input per unit length decreases as the magnification of the recording speed grows high and the pit is hardly formed, the pit power is made to raise so as to form a proper pit. Simultaneously the bottom power is raised so that the difference from the pit power does not increase too large and the prolongation of the fall time of the returned waveform is prevented.
