Title: Face opposed type motor
Inventor: KAWAKAMI YOSHIO
IPC: H02K1/27
Filed: 1990-03-29
Abstract: PURPOSE:To obtain a high FG output without the decrease of a torque by forming the magnetization level averaged over a plurality of magnetic poles in the outer peripheral part of a rotor magnet, which oppose to one main magnetic pole in the inner peripheral part of the rotor magnet, so as to deviate to the same polarity side as the polarity of the one main magnetic pole. CONSTITUTION:The whole of the inner peripheral part 1b of a rotor magnet 1 is divided equably into even number of regions with a predetermined angle, and these regions are magnetized alternately with different polarities as main magnetic poles for driving a motor. Also, the whole of the outer peripheral part 1a of the rotor magnet 1 is divided equably into regions with a smaller predetermined angle than that of the inner peripheral part 1b, and these regions are magnetized alternately with different polarities as FG magnetic poles constituting an FG. In the magnet 1, the magnetization levels in the outer peripheral part 1a, averaged over the 5 FG magnetic poles which oppose to the one main magnetic pole in the inner peripheral part 1b, are deviated to the same polarity side as the polarity of the one main magnetic pole of the part 1b. By making the magnetization level averaged over a plurality of magnetic poles deviate to the same polarity side as the polarity of the one magnetic pole in this manner, even if decreasing the number of the magnetic poles in the rotor magnet for a frequency generator, no motor torque is made to reduce.

Title: Method for foam molding
Inventor: MACHIHARA AKIO
IPC: B29K105/04
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To eliminate the formation of a gap in a molding, to facilitate the removal after molding, and to reduce flash by laminating an expandable sheet of a specified expansion ratio on a surface which continues from the inner surface to the slit of a mold before filling. SOLUTION: When a product as a composite material is produced, a member which is not deformed even when subjected to a reaction by foaming such as metal, synthetic resin, and resin-coated paper is set in a mold in advance. Before filling, an expandable sheet 10-60 in expansion ratio in which a material such as foam of a rubbery substance of silicone, etc., foam of a synthetic resin such as polyethylene, and foam of an inorganic substance such as glass is used is laminated on a surface which continues from the inner surface to the slit of the mold. As a result, even when the slit breadth of the mold is appropriate to some extent, no gap is formed in a foamed resin molding, the molding can be removed easily, and burrs can be reduced.

Title: Image pickup unit
Inventor: YAMAZAKI YASUYUKI
IPC: H04N5/243
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To obtain a unit which displays an excellent image by adding outputs of plural pixels, changing the number of pixels to be added, and changing a gain to an output of the pixel in a direction which negates change in signal to be obtained by addition. SOLUTION: In a system control circuit 21, a CCD driving circuit 14 is controlled so that it drives reading of a CCD 13 when it is judged from a video signal from an image pickup signal processing circuit 16 that a subject is dark. Since a video signal to which a charge of a pixel is added is outputted when the CCD 13 is driven, a video signal of a level higher just for the added charge is outputted from the CCD 13. In the system control circuit 21, a reading mode of the CCD driving circuit 14 is switched and, at the same time, a gain of a gain control circuit 15 is controlled so that it is in inverse proportion to the level of the video signal higher just by an added amount.  Since the level of the video signal outputted by the gain control circuit 15 is held constant even if the number of pixels to which charge is added is changed, an image to be displayed on an LCD 19 does not change.

Filed: 1987-03-31
Abstract: PURPOSE:To reduce noises to a detecting element and to shorten the cooling time of the detecting element by providing a shield body which has a corner cube reflecting mirror array body and inhibiting a reflected infrared ray from impinging on the infrared detecting element. CONSTITUTION:The shield body 7 is arranged in a dewer 1 at a distance from a cooling part 6 which cools the quantum type infrared detecting element 4 while surrounding the element 4. The shield body 7 has an opening part where the infrared ray 11 to be measured passes and also has the corner cube reflecting mirror array body 8 arranged opposite the element 4. The reflecting mirror array body 8 has a high reflection factor and reflects the incident light nearly in its incidence direction. Then the infrared ray 11 is detected by the element 4 and an unnecessary infrared ray 12 which travels to the element 4 from outside the detector is cut off by the shield body 7 which has the reflecting mirror array body 8 and never incident on the element 4. The reflecting mirror array body 8 reflects the infrared ray nearly in its incidence direction, so the unnecessary infrared ray 12 from outside a necessary visual field is prevented from being incident on the element 4 after being reflected here.

Inventor: NISHIHARA MASAHIRO
IPC: H04N1/407
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To prepare gradation characteristic data by a work for a short time by measuring a density level from a common patch by plural colors regarding a patch corresponding to a lower limit value at an input level. SOLUTION: A color patch necessary for measurement of a density level is printed and outputted by a printer 2. First of all, when the density level of the patch is measured by a colorimeter 3, the density level (an actual output level) is fetched in a personal computer 1. Subsequently, an output level (a predicted output level) corresponding to an input level of the measured patch is read from reference calibration data. Then, if a difference between the actual output level and the predicted output level is within a specified range, the actual output level is stored as valid calibration data. Interpolation is performed between the measured output levels and the density level to be actually given to the printer 2 at the time of printing is obtained.

Abstract: PURPOSE: To obtain a petroleum resin less contaminated with ash, etc., by polymerizing polymerizable unsaturated hydrocarbons of a petroleum distillate with the aid of a Friedel-Crafts catalyst and contacting the reaction product with a water phase in the presence of a polyoxyethylene derivative.  
     CONSTITUTION: Unsaturated hydrocarbons obtained by thermal cracking or a like processing of petroleum are polymerized in the presence of a Friedel-Crafts catalyst (e.g., anhydrous aluminum trichloride). After completion of the polymerization, the oil phase containing a polymerization reaction mixture is contacted with water or an aqueous alkali solution in the presence of a surfactant, e.g., polyoxyethylene, (used in an amount of 0.1W200ppm, based on water phase used). After separating the water phase, the oil phase is subjected to short stopping, catalyst removal and deashing. The amount of water or an aqueous alkali solution used is usually 20W200pts.wt. per 100pts.wt. oil phase. In this way, a sufficiently low-ash resin is obtained.
