Title: Magnetic recording medium
Inventor: UMEBAYASHI NOBUHIRO
IPC: C09D5/23
Filed: 1994-08-03
Abstract: PURPOSE:To enable execution of excellent optical servo tracking even at 100 TPI or above by a method wherein the light transmittance of a disk having a magnetic layer is set at a prescribed value or below. CONSTITUTION:A magnetic layer 8 of an aimed thickness is formed by applying coating l and magnetic coating 2 on a film 6 by using a coating head 3 and it is made a thin film of a thickness being equal to or less than the wavelength of irradiating light. Besides, a large number of recessed parts 20 for magnetic head tracking are formed at prescribed intervals on the surface of the magnetic layer 8. When the tracking of a magnetic head is conducted by casting light on the recessed part 20 and a data track 21, reflected light suppresses the interference of light due to variation in the thickness of the magnetic layer 8 and, moreover, scattering of light is suppressed by making a surface roughness be l/50 or below of the irradiating light. In this case, the light transmittance of a disk 13 having the magnetic layer 8 is made 5% or below, or preferably 3% or below.

Abstract: PURPOSE:To obtain a copy of constant density even if an original deep on the background and one light thereon are copied at the same time, by installing a means for lowering the potential of a latent image on the specified part of a photosensitive drum surface. CONSTITUTION:The specified region of the original is designated by feeding each 2 points (X1, X2), (Y1, Y2) of the 2 sides X, Y of an original platen A with ten keys. The surface of a photosensitive drum having an electrostatic latent image formed after the steps of charging and imagewise exposure is exposed to light scanning of the array of light emitting diodes lighted selectively to weaken the electrostatic latent image on the part corresponding to the designated region. As a result, in the case of, e.g., newspaper deep on the ground at the designated region, and a usual original on the other region, a copy equal in density can be obtained. The illumination of the light emitting diodes can be changed in ten steps with input of the ten keys, so it can be adapted to a variety of ground densities.

Abstract: PROBLEM TO BE SOLVED: To avoid difference in the surface level which inhibits the alignment treatment by filling the space between black pigment patterns with a transparent organic resin having almost the same thickness as that of the black pigment to flatten the surface of an active substrate. SOLUTION: A positive photosensitive transparent resin 64 is applied on a glass substrate 2 and irradiated with UV rays 62 from the lower side of the glass substrate to expose the resin 64. As a result, the space between black pigment resist patterns 60' except for the opening 63 on a drain electrode 21 can be filled with the photosensitive transparent resin 64' (b). Then a transparent conductive ITO film 65 is applied on the glass substrate 2, and a negative photosensitive resin 66 is applied thereon. The opening 63 of the drain electrode and its adjacent region are selectively irradiated with UV rays 62 from the upper side of the glass substrate 2 by using a photomask 61, while the photosensitive resin 66 is wholly irradiated with UV rays from the lower side of the glass substrate 2 (c).  Thereby, a photosensitive resin pattern in the same size as the photosensitive resin 64' can be obtained.

IPC: G06K9/50
Filed: 1981-12-18
Abstract: PURPOSE:To recognize characteristics of details in matching with the structure analysis through thin lines, with a comparatively simple processing by performing processing incorporating directional code labels. CONSTITUTION:A direction code label pattern pickup circuit 7 provides a directional code label for the content of an input character memory 6. A label series incorporating circuit 8 picks up label series sets collected vertically and incorporatedly. Further, a rough classification circuit 9 performs rough classification and limits a range where recognition objective characters belong. The result is informed to a label series characteristic dictionary 10 and a label series indirect connection relating dictionary 13. A discriminating circuit 11 checks whether or not each label series of the standard characteristics exists in the label series set. When not exists, the character is rejected from the candidates of the answer. In the stage when the existence is clear, a discrimination circuit 14 collates the order of production of the label series. Through the comparatively simple processing as the incorporation of the directional code label, the recognition as to the detailed characteristics is done.

IPC: H01L29/762
Filed: 1993-08-19
Abstract: PURPOSE:To control formation of interface level of a MONOS type charge transfer element by avoiding influence of fault generated by implantation of fluorine ions. CONSTITUTION:After a channel region 2 and a channel stop region 3 are formed in a silicon substrate 1, a silicon oxide film 4 is formed on the silicon substrate 1 and a nitride film 5 is successively formed by the CVD method. Thereafter, using an ion implantation apparatus, fluorine ions are implanted so that the range lies within the silicon oxide film 4. Moreover, heat treatment in a nitrogen atmosphere results in diffusion of fluorine ions into the interface between the silicon substrate 1 and silicon oxide film 4. Thereby, the dangling bond existing on the interface can be terminated to control formation of the interface level.
