Title: Focus detecting method and automatic focusing device for display
Inventor: SAKUMA SHIGERU
IPC: H01J9/44
Filed: 1991-07-09
Abstract: PURPOSE:To execute satisfactory focusing without experthess of a worker by automating the focusing of display. CONSTITUTION:A character pattern displayed on a display 1 to be focused is divided into plural screen sections and photographed by the TV cameras 2a-2e. Based on these image pickup outputs, the component value of the space frequency is obtained by a BPF 4. Then a focus shift extent is calculated from the average component value. At the same time, a CPU 9 drives a focus control means of the display 1 via a motor 12 in order to obtain the maximum focus shift extent. In such a constitution, the focus state of an entire screen is controlled in good balance by means of a control pattern equal to the visual control. Thus the satisfactory focusing is attained with the good correlation secured with the visual control.

Title: Estimation method of magnetic field generation source
Inventor: SEKIHARA KENSUKE
IPC: A61B5/05
Filed: 1991-07-09
Abstract: PURPOSE:To achieve higher estimation accuracy of a current distribution in an apparatus which has a plurality of detection coils and performs a measurement at a plurality of measuring points simultaneously to estimate and display a magnetic field source in an organism from a magnetic field data of an organic surface obtained. CONSTITUTION:In the measurement of an organic magnetic field, a magnetic field from a magnetic field source outside the organism acts as noise to lower estimated accuracy of the magnetic field source in the organism. When magnetic fields at a plurality of points are measured simultaneously with a plurality of detection coils, attentions are paid to correlation of the noise between channels to estimate a covariance set C of the noise beforehand (102, 103). Thus, a magnetic field parameter is determined so as to maximize a logarithmic allowance E as given by the formula (3). (104).

Title: Original reader
Inventor: OGUSHI HIROSHI
IPC: H04N1/04
Filed: 1989-06-28
Abstract: PURPOSE:To improve the read start accuracy and to obtain a reader possible for miniaturization by containing an original end sensing means to one member of an original read unit. CONSTITUTION:When an original 1 is carried, a light passing through an optical path 7 is reflected at the tip of an original and reaches a photodetector section 5 of a position S1 to detect the tip of the original and the light through an optical path 8 is read as an original image at a read section at a position S2. Then the reading is stopped after a prescribed time when the absence of the reflected light on the original face from the light path 7 is detected. Thus, it is possible to arrange an original tip sensing means and a picture read means close to each other and the positions S1, S2 are placed onto a member 61 being an integrated member, then the read accuracy is high and error is less and since the light source is used in common, number of components is reduced and then the necessity of replacement of defective components is less.

Title: Semiconductor laser
Inventor: IMAI HAJIME
IPC: H01S5/16
Filed: 1984-08-11
Abstract: PURPOSE:To obtain a semiconductor laser, which projects laser beams having a single wavelength and coupling structure thereof with an optical fiber can be simplified, by forming the projection end section of beams on at least one side of an active layer or an optical guide layer in thickness thicker than the inside of the layer. CONSTITUTION:An active layer 3a is grown on an optical guide layer 8a in the same epitaxial manner as an active layer 3, and an upper surface thereof is flattened approximately and the thickness of projection end sections 10 thereof are made thicker than the inside thereof. Consequently, only a thin section in the active layer 3a functions as a light-emitting region, and emits laser beams having plane waves, but the beams are changed into curved surface waves because the thickness of the active layer 3a and the optical guide layers 8a is increased when the beams reach the projection end sections 10, thus hardly interfering in the action of corrugation 9 even when the beams are reflected by the projection end surfaces, then projecting as single wavelenths. The projection end sections 10 in the active layer 3a do not function as the light-emitting region, thus resulting in no damage of a predetermined luminescent function even through a mechanical contact, then allowing the butt-joining of an optical fiber.

Title: Production of painted steel sheet having high brightness
Inventor: TANDA TOSHIKUNI
IPC: B05D7/14
Filed: 1987-07-08
Abstract: PURPOSE:To produce a painted steel sheet having extremely high brightness by subjecting the steel sheet which is adjusted in surface roughness by temper rolling to a specific value or below to bright Zn-Ni plating, then subjecting the steel sheet further to the temper rolling to adjust the surface roughness to a specific value or below. CONSTITUTION:The surface roughness of the steel sheet is adjusted to <=0.2mu Ra by subjecting the steel sheet to the 1st temper rolling. After this steel sheet is subjected to the bright Zn-Ni plating, the steel sheet is further subjected to the 2nd temper rolling to adjust the surface roughness to <=0.1mu Ra and a painting treatment is applied thereon. The painted steel sheet having the excellent brightness exceeding the conventional level is obtd. by this method. The brightness is poor if the roughness by the 1st temper rolling exceeds 0.2mu in the above-mentioned method. The brightness of a required level is not obtainable if the roughness by the 2nd temper rolling exceeds 0.1mu. The smoothness of the Zn-Ni plating surface is greatly improved by subjecting the steel sheet to the bright plating added with a brightener such as polyethylene imine. The brightness is extremely improved by said plating as well as by the 2nd temper rolling.

Title: Production of main magnetic pole for vertical magnetic recording head
Inventor: OOSAWA RIYUUJI
IPC: G11B5/31
Filed: 1983-09-13
Abstract: PURPOSE:To improve the reliability of a vertical head as well as the production yield of a main magnetic pole for vertical magnetic recording head, by forming parallel magnetic fields on the surface of a substrate and deciding as desired the direction of the magnetic anisotropy of an obtained magnetic thin film of high permeability. CONSTITUTION:A yoke plate (''Permalloy'') 8 made of a material of high permeability and magnets 9 and 9' are distributed to a substrate holder 6, and a substrate 7 is set at the center between both magnets. Here the polarities of both magnets 9, 9' are set opposite to each other to obtain a line of magnetic force 10 on the substrate 7 as shown by a figure (c), and parallel and intensive magnetic fields are generated on the surface of the substrate 7. Then a ''Permalloy'' film is formed on the substrate 7 by a sputtering process by means of the holder 6. A magnetization facilitating axis is set in the direction 11 of the parallel magnetic fields; while a magnetization unfacilitating axis is set in the direction 12 orthogonal to the direction 11. Thus it is possible to form a magnetic thin film of high permeability which has the magnetic anisotropy in the desired direction. In this way, the reliability of magnetic characteristics of a main magnetic pole is improved as well as the production yield of the magnetic pole.

Abstract: PURPOSE:To reduce an impact sound without increasing a weight and without adding a component by forming a material of a platen or a material of a cutter base to be collided at the time of returning a cutter for cutting a print sheet of a vibration damper. CONSTITUTION:An impact dot head 1 has a striking function and a platen 2 has a function for receiving an impact by striking the head 1. An ink ribbon 3, a print sheet 4 are interposed between the head 1 and the platen 2. Ink of the ribbon 3 struck to the head 1 is transferred to the sheet 4. Simultaneously, the struck platen 2 is vibrated to generate a print sound, but since a material of the platen 2 is formed of a thin-plate damper of a three-layer structure, vibration of the platen 2 struck by the head 1 is attenuated by properties intrinsic for the damper for suppressing vibration as known, thereby reducing the print sound.
