Inventor: TANAKA TETSUOMI
IPC: G06K9/62
Filed: 1994-10-03
Abstract: PURPOSE: To speed up the processing by excluding standard data from a selection of data when it is judged through attribute comparison that both attributes do not meet comparison standards. CONSTITUTION: An attribute decision part 105 inputs attribute data corresponding to a standard pattern in an attribute memory 103 together with an arithmetic result (data showing similarity) from an arithmetic part 104, and compares it with initially set attribute data. When they match each other, it is outputted to a sorting part 106 together with its identifier. When not, on the other hand, it is not outputted to the sorting part 106 and an advance to an arithmetic process for a next standard pattern is made. Thus, the operations are repeated and when the operations end, the arithmetic result and identifier of high-order data selected by the sorting part 106 are taken out.  In this case, data which does not match the necessary attribute are not inputted to the sorting part 106, so the data that do not match the necessary attribute are never selected whatever value the arithmetic result has.

Filed: 1986-10-09
Abstract: PURPOSE:To measure a current with high accuracy even in environment where vibrations and temperature variation are large by providing Faraday effect materials in a storage case flexibly by elastic rubber, etc. CONSTITUTION:The Faraday effect materials 1a-1d have mutually parallel light incidence surfaces 2 and emitting surfaces 3 and fixed to the storage case 5 by elastic bodies 4 so as to surround a conductor 17 while maintaining flexibility. Then the rays of light emitted by optical fibers 12a-12c are incident on the effect materials 1a-1d reflected by reflecting mirrors 15a-15c and 16 to return 1st radiation points through the same path as the going paths, so even if the effect materials 1a-1d are displaced, there is no variation in the light receiving quantity and excellent characteristics are obtained against vibrations. Further, the effect materials 1a-1d are fixed flexibly, so mechanical stress due to temperature variation is small and an error in measurement due to the temperature variation can be removed.

IPC: B05B7/02
Filed: 1993-08-31
Abstract: PURPOSE:To adjust static electricity of powder by preventing drying of a spraying material at a tip of a nozzle and also arbitrarily adjusting the spraying material during spraying.

Title: Production of optical information recording and reproducing carrier
Inventor: OOTA TAKEO
IPC: G11B7/26
Filed: 1983-12-19
Abstract: PURPOSE:To form extremely easily a desired thin film by using a mixture of oxides of a metal equivalent to a chemical equivalent weight ratio or a metalloid and a single unit of a metal or metalloid as an evaporation source and then controlling one evaporation source only. CONSTITUTION:A substrate 6 is revolved by means of a shaft 7, and a vapor deposition source material 9 is evaporated to form a thin film 10 on the substrate 6. This film 10 has a composition MOx, where M means a metal or a metalloid, O is oxygen (O<x<A) and A means the value showing the quantity of oxygen in the form of a specific chemical equivalence ratio in case the quantity of M is set at 1. Then the oxide and a single metal are weighed and mixed so that the oxygen is set at a desired non-chemical equivalence ratio. In such a way, the material 9 is obtained. The composition varies between the material 9 and the film 10 owing to extensive differences of vapor pressure. However the vapor pressure difference is greatly reduced at a high temperature area and therefore the difference of composition is also reduced. In this respect, it is desirable to apply a sputtering process or an electron beam heating process, etc. in place of a resistance heating process.

Abstract: PURPOSE:To increase the distance between a bar-like light source and LCD and thereby protect LCD against the thermal effects of a light source by providing an optical system which condenses light from each bar-like light source in a vertical direction against the longitudinal direction of the bar-like light source and guides the condensed light to an LCD array. CONSTITUTION:Each one of convergent optical systems 5-1, 5-2, 5-3 installed between bar-like light sources 1-1, 1-2, 1-3 and LCD2 capture the scattered light from the bar-like light sources 1-1, 1-2, 1-3 at a broad opening. This captured light is converged and projected to LCD2. Consequently, the distance between the bar-like light sources 1-1, 1-2, 1-3 and LCD2 can be increased so that the thermal effects of the light sources 1-1, 1-2, 1-3 upon LCD2 are blocked. At the same time, a higher intensity of light can be projected to LCD2 compared to the light intensity when the distance is short, in spite of the fact that the distance is long.

Title: Color image adjustment device and color image adjustment method
Inventor: HAYASHI SHUJI
IPC: H04N1/60
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To adjust saturation in an excellent way by making total sum of color image data in 3-primary colors equal before and after the adjustment. SOLUTION: A color CCD element 23 has, e.g. R, G, B color films to each picture element and provides the output of analog image signal of RGB components for each picture element. Furthermore, a conversion circuit 25 converts an analog image signal outputted from the CCD element 23 into digital color image data representing the density of each of cyan C, magenta M, yellow Y and provides the output of the result. Then highest density data and lowest density data in the C, M, Y data are changed in inverted direction mutually and the relation of quantity among the C, M, Y is kept similarly with respect to that of the original data. In addition to the comparatively simple saturation adjustment as above, the total sum of image data is kept before and after the adjustment.  Thus, the saturation adjustment is processed in an excellent way without being attended with the change in the lightness.

Abstract: PURPOSE:To improve both silencing performance of an exhaust system and output performance of an engine by brunch-forming a normally opened passage and an opening/closing passage in which an opening/closing valve is interposed downstream from an auxiliary silencer provided with a resonant chamber and communicating the normally opened passage and the opening/closing passage with a pair of main silencers of different kinds. CONSTITUTION:When respective opening/closing valves A, B, for example, both of them are closed and respective right/left second rear tubes 29 35 are closed, exhaust flows through only right/left first rear tubes 28, 34 downstream from an auxiliary silencer 27. When this case is compared with such a case as the right/left second rear tubes 29, 35 are in opened condition, an exhaust cross section is reduced. Hence, exhaust pressure is raised due to increase of exhaust resistance so as to improve silencing performance. The respective right/ left, second rear tubes 29, 35 are closed at the positions of respective distances l1, l2 from the branch parts of respective first rear tubes 28, 34 so as to form branch pipes having their distances l1, l2 to silence exhaust noise having specified frequency by resonator action. At this time, the auxiliary silencer 27, eliminates specified frequency by the resonator action of a resonator 40.
