Title: Production of thin film magnetic head
Inventor: ICHIKAWA HITOYOSHI
IPC: B24B49/04
Filed: 1986-07-29
Abstract: PURPOSE:To enable formation of the depth of a gap material with high accuracy by providing a polishing control mark consisting of an inter-layer insulating material sandwiched by a lower base consisting of lower magnetic material and upper base consisting of an upper magnetic material and polishing the gap material down to the depth at which the mark disappears. CONSTITUTION:The polishing control mark part 11 exposes its section on progression of the polishing in a gap depth polishing stage. While 'Permalloy(R)' has metallic gloss, an org. insulating material is non-glossy or transparent at this time; therefore, the polishing control mark 14 consisting of the org. insulating material sandwiched by the 'Permalloy(R)' is easily visually detectable of its presence when light is projected thereto. The detection of the point of the time when the presence thereof disappears is consequently extremely easy and distinct. The polishing can be stopped at the time of said disappearance. The gap depth is thus formable with high accuracy by such polishing and stop coupled with the improved accuracy of the mark position resulting from the formation of the polishing control mark by the inter-layer insulating material.

Title: Manufacture of small-sized superconducting solenoid
Inventor: NISHIGUCHI KATSUNORI
IPC: H01B12/06
Filed: 1987-07-16
Abstract: PURPOSE:To make it possible to manufacture a compact, practical solenoid using a composite oxide material at an industrially low cost, by forming at least two lines of through holes in a substrate, and forming a thin film layer comprising a composite superconductive oxide material so as to cover the upper and lower surfaces and parts of the surfaces of the through holes by a physical evaporating method. CONSTITUTION:At least two lines of through holes 5 are formed in a substrate 1. A thin film layer 8 comprising a composite superconductive oxide material is formed so as to cover the upper and lower surfaces of the substrate 1 and at least parts of the surfaces of the through holes 5 by a physical evaporation method. For example, resist is applied on a silicon wafer 1. Thereafter, the wafer is exposed so as to obtain a through hole pattern as shown in the Figure. The through holes 5 are formed by etching. Then, the entire silicon wafer 1 having the through hole is heated. Thus a thermal oxide film 7 is formed on the entire surface. Thereafter, a thin film layer 8 of a superconductive material is formed by sputtering. Finally, a core part 10 having the thin film layer 8 of the composite oxide is divided by dicing, and many solenoids are obtained.

Filed: 1983-09-28
Abstract: PURPOSE:To decrease considerably crosstalk irrespectively of whether a distinct coloring or discoloring threshold voltage exists or not by using a solid electrolyte layer and forming an electrocoloring element on a switching matrix circuit using a thin film transistor. CONSTITUTION:An oxide mixture (ITO) composed of In2O3 added with SnO2 is deposited by evaporation on a TFFET matrix 3 to form a transparent electrode and the electrode is photoetched to form picture element electrodes 2 into a dot matrix shape.

An oxide mixture composed of ZrO2 and Y2O3 is deposited by evaporation thereon to form a solid electrolyte layer 6. ITO is then deposited by evaporation and a counter electrode 7 is formed over the entire surface of the element. A sealing layer 8 is formed thereon. The crosstalk between the lines and rows is eliminated at all by the above- mentioned constitution.

Title: Recognition device for pieces on japanese chess board
Inventor: UMAGAMI KEIICHI
IPC: G06T1/00
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To easily recognize the existence or non-existence of Japanese chess pieces and raise a judgement treatment rate for the existence or non-existence of the pieces by preparing a histogram on the basis of an inter-image computation result between a label image and an edge extracted image, and applying a threshold value to the histogram. SOLUTION: An edge extracted image is generated from the images of pieces on a Japanese chess board picked up via a CCD camera 1, using the first luminance value of square lines on the board and characters on each piece, and the second luminance value of the bare surface of the board. The preset inter-image calculation is then made between a label image at a position corresponding to the inside of each square on the board in the edge extracted image, and the edge extracted image for obtaining the image where only a picture element having the first luminance value among picture elements having the first and the second luminance values becomes a luminance value for a corresponding label in zones corresponding to each label on the edge extracted image.  At the same time, a histogram is prepared to show the frequency of picture elements for the luminance value, based on the image so obtained, and a frequency for each luminance value is compared with a threshold value to judge the existence or non-existence of pieces.

Title: Structure for cooling electronic part
Inventor: TSUKAMOTO KENJI
IPC: H05K7/20
Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To increase a cooling area by forming a coolant path to an outer side from the center part of first and second heat sinks with the fitting face of a first radiating fin and the fitting face of the second radiating fin, which are fitted to the first and second heat sinks and which are coaxially arranged. SOLUTION: Compressed air produced by an air compressor 7 passes through a tube 4 and it is ejected from a nozzle 3 to the center part of the heat sink 2. Air ejected from the nozzle 3 rises along the radiating fin at the inner side of the heat sink 2, passes through a part between the fitting part of the heat sink 1 and an adjacent fitting part and descends along the radiating fin at the inner side of the heat sink 1. Thin, air rises along the outer fin of the heat sink 2, passes through the fitting part with the heat sink 1 and the adjacent fitting part, drops along the fin at the outer side of the heat sink 1 and it is discharged outside. Thus, the cooling area can be increased.

Filed: 1988-07-20
Abstract: PURPOSE:To detect an erroneous operation generating source easily and rapidly in circuit planning by comparing the simulation result of a logical circuit with an expected value. CONSTITUTION:The output result obtained by simulation is compared with an expected value and, when the whole coincides, inspection is finished. When non-coincidence is detected, a logical circuit diagram is displayed on a graphic display. As one example, when the non-coincidence with the expected value is detected in two output signal values O1, O2 with respect to different input signal patterns, at first, the signal exerting effect on the signal value of the signal O1 is traced toward an input part on a logical circuit with respect to the signal O1 and the propagation route of said signal is displayed, for example, by changing the color thereof. Next, the same operation is performed with respect to the signal O2 and a separate color is superposed. Then, it is estimated that there is an error in the logical element present on the route becoming much in the superposition of colors at last, herein, in a logical element (g).
