Inventor: IZUKAWA KAZUHIRO
IPC: G03B27/32
Filed: 1990-01-26
Abstract: PURPOSE:To easily mount a sheet on a tray in none of wrong top reverse relation, upside-down relation, and wrong right-left relation by forming the sheet for the image file in a shape of point asymmetry and axial asymmetry. CONSTITUTION:The sheet 11 is formed by arranging plural films 12 which are already developed in a lattice shape.

IPC: H01L29/73
Filed: 1982-02-08
Abstract: PURPOSE:To obtain a Darlington transistor with improved breakdown strength by a method wherein the base region scheduled region of the front transistor is formed in a recess, and then the base width is changed. CONSTITUTION:The front transistor 1 and the rear transistor 2 have the base region and the collector region in common, and the transistor 1 is formed in a recess on the surface of the base region, accordingly formed thinner than the base region of the transistor 2. Since the (P type) impurity density of the surface is low, the depth xj1 of an emitte region next formed by diffusion is larger than the xj2 of the transistor 2. The base width WB1 of the transistor 1 becomes smaller over the difference of levels on the surfaces of the base regions compared with the base width WB2 of the transistor 2. The sustaining voltage of the transistor 1 can be set by the extension of the transistor 1 base width and adjusted by the etching amount.

Title: Production of oxide superconducting thick film
Inventor: HASEBE TSUGUNORI
IPC: C01G29/00
Filed: 1989-01-30
Abstract: PURPOSE:To obtain the title dense thick film causing no crack or debonding by attaching a pasty oxide superconducting material of e.g. Y-Ba-Cu-O-base to a ceramic substrate prior to sintering and by simultaneously baking the substrate and the superconducting material. CONSTITUTION:A pasty oxide superconducting material such as YBa2Cu3Oy or Bi2(Sr, Ca)4Cu3Oy is attached to a ceramic substrate prior to sintering. The ceramic substrate is pref. a ceramic having the baking temperature close to the normal baking temperature for oxide superconducting materials or an electrical insulating ceramic, a Cu-contg. oxide such as La2CuO3. Thence, the substrate and the superconducting material are simultaneously baked to obtain the objective oxide superconducting thick film.

Abstract: PURPOSE:To improve the transfer efficiency of horizontal CCD's in a CCD type element by a method wherein the area of a CCD electrode at the part that receives signal charges from a vertical CCD shift register is made larger than that of another electrode. CONSTITUTION:When two receiving openings are provided, a the electrode dimensions L1'' and L2'' of two CCD electrodes 9''-1 and 9''-3 becomes larger than those of the other electrodes 9''-2, 9''-4-9''-6. If the dimensions L1'' and L3'' of the electrodes 9''-1 and 9''-3 corresponding to the two receiving openings are (P-3XIImin)/2, the dimensions of the L1'' and L3'' become the maximum in six CCD electrodes. The electrode capacitance of the receiving opening can be increased to approx. 1.5-2 times of that in the conventional element: it becomes possible to restrict charges for a potential increase VS in the case of their transfer to this electrode to 1/1.5-1/2, thus enabling those for an increase VY to be reduced; accordingly, inflow of charges to projections 11 is prevented.

Abstract: PURPOSE:To obtain an impregnated carbon material having low porosity in high productivity by impregnating pitch in a carbon material having low density, infusibilizing exclusively the surface part of the carbon material and then the whole carbon material and carbonizing or graphitizing the material. CONSTITUTION:A carbon material such as coke is mixed with a binder such as pitch and the mixture is formed and then carbonized or graphitized to produce a low-density carbon material such as artificial carbon or artificial graphite. The low-density carbon material is impregnated with pitch (e.g. coal tar pitch) and exclusively the surface part of the carbon material is quickly heated above the softening point of the impregnated pitch to infusibilize the pitch and prevent the flow-out of the impregnated pitch. The exclusive infusibilization of the surface part is preferably carried out by blasting hot air against the surface part with a drier, etc. Thereafter, the carbon material is infusibilized as a whole and the material is carbonized or graphitized to obtain a carbon material having low porosity without repeating the impregnation of pitch.

Abstract: PURPOSE:To stably execute a focusing by making a wavelength plate rotatable around an axis parallel to an optical axis by a rotating means and feedback- controlling it so that the total light receiving quantity of a light receiving element for focusing may be constant. CONSTITUTION:A wavelength plate 12 is arranged between a laser beam source 10 and a reflecting prism 14 and the wavelength plate 12 is provided rotatably around the axis parallel to the optical axis. When the wavelength plate 12 is rotated around the axis parallel to the optical axis, the quantity of light transmitting through a polarizing beam splitter 16 changes the total light receiving quantity of a light receiving element 24 for focusing changes. When a feedback is applied to the rotating means and the rotation of the wavelength plate 12 is controlled so that the total light receiving quantity of the light receiving element 24 for focusing may be always constant, the inclination of an S-curve in a focusing control can be kept always constant regardless of the fluctuation of reflectance. Thus, the focusing can be stabilized.
