Title: Method and device for image recognition
Inventor: UNO MASAHIKO
IPC: G06K9/62
Filed: 1999-07-06
Abstract: PROBLEM TO BE SOLVED: To easily recognize flaws or dirt on an examination object without performing alignment by discriminating the partial area of the image of the object and the partial area of a teaching image are equal, when a first output image is close to an image having the luminance value of zero. SOLUTION: A differential output is generated for partial areas provided in a partial area selecting process, with respect to the teaching image preserved in a teaching image data base 7 by a teaching image preserving means 6 and the image of the object. The first output image is generated, by measuring plural luminance differences inside areas, while considering a deviation quantity. The luminance of the first output image is analyzed, and a normal/defective condition is decided corresponding as to whether the first output image is close to the image with the luminance value of zero. Concerning this decision, if a differential count value diff-cnt does not exceed a designated threshold Diff-Th, the object is decided as being non-defective but otherwise, the object is considered as being defective.  When larger the pixels having the great luminance value in the first output image are, the larger this differential count value becomes and this turns into an index as to whether the first output image is close to the image with the luminance value of zero.

Title: Control device for hydraulic pump
Inventor: WATANABE HIROSHI
IPC: F15B11/05
Filed: 1990-07-20
Abstract: PURPOSE:To improve operability by comprising a means for determinding a taget value of a difference between the discharge pressure of a hydraulic pump and the load pressure of an actuator so as to be increased when temperature of the pressure oil for actuator is lowered and reduced when that temperature rise. CONSTITUTION:A control unit 7 inputs for memory the output of an oil temperature detecting unit 12, a differential pressure detecting unit 5 and an inclined plate position detecting unit 6, and computes a target differential pressure with the oil temperature signal. Next, a deviation of the differential pressure between the target differential pressure value and the differential pressure signal, and computes an inclined plate target position of a hydraulic pump 1 with integral control to control the inclined plate position. When oil temperature is lowered, the target differential pressure is increased, and since an inclined plate 1a is controlled at a target position so that a real differential pressure coincides with the target differential pressure, a rise of the differential pressure by a rise of viscosity of the operating oil is compensated, and the hydraulic pump 1 is controlled so as to obtain a discharge quantity corresponding to an operation quantity of an operating lever 3a. In the case that the oil temperature signal rise, control is performed similarly. Consequently, excellent operability independent of a change of oil temperature can be obtained.

Title: Manufacture of semiconductor device
Inventor: KATOU TERUO
IPC: H01L21/314
Filed: 1983-10-17
Abstract: PURPOSE:To enable composition of high-resistance SiC as an insulating film or a protective film and to prevent generation of a crystal defect by thermal expansion coefficient of that and further to enable thickening of the film by implanting BeO, BN or the like in the SiC formed in advance by ion implantation method. CONSTITUTION:A low-resistance SiC polycrystalline film 2a formed on a main surface of an Si single crystal substrate 1 by ion implantation is doped with BeO so as to make the film insulating, i.e. high-resistance. For the ion implantation, a solid source of BeO as an ion source is used or a solid surce of Be and a gas source of O are used together to perform a heat treatment. Next, after the SiC film 2 is selectively removed by etching, impurity such as arsenic is doped in the main surface of the exposed Si substrate 1 to form a buried layer 3, on which an epitaxial layer 4 is formed and n and p type impurities are selectively diffused. As thermal expansion coefficients of the high-resistance SiC film 2 and the Si substrate 1 are equal, stress is not generated in the Si single crystal even if the SiC films 2 and 6 are formed to be thick.

Title: Backprojection transmission type screen
Inventor: TACHIBANA KAZUHIRO
IPC: G03B21/625
Filed: 1990-07-20
Abstract: PURPOSE:To effectively prevent the occurrence of a cone or a rainbow and to obtain a high-quality image without changing the shape of a Fresnel lens by disposing a polarizing film on the exiting side of light from a light source with respect to the lens surface of the Fresnel lens. CONSTITUTION:The polarizing film 34 is disposed at least on the exiting side between the incident side and the exiting side of the light from the light source with respect to the lens surface of the Fresnel lens. Therefore, in the case that the light from the light source which is made incident on the Fresnel lens is polarized light projected from a liquid crystal projector, for example, the polarizing film 34 is made to function as an analyzer. Therefore, main light from the light source is made to be transmitted through the Fresnel lens but stray light reflected inside, which is transmitted through the polarizing film 34 and emitted from the lens surface, is remarkably reduced because the plane of polarization of most stray light is changed. As a result, the cone or the rainbow caused by the stray light is prevented from occurring and the image quality of a screen is improved.
