Title: Steering apparatus and attachment tool used for the same
Inventor: TSUJI YASUAKI
IPC: B62D1/19
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To enable the holder to be attached by fixing the attachment tool to the housing by providing, to an attachment tool for attaching a housing to a vehicle body, a coupling portion to which a holder for holding an interlocking cable interlocked with an operating portion is coupled. SOLUTION: A coupling portion 35 is integrally provided on one side of a lower portion of an attachment tool 3 for attaching a lower end of a housing 2 to a vehicle body. This coupling portion 35 has a pair of through holes spaced apart from each other. A holder 7, formed by molding a metal plate, has a pair of through holes at one end corresponding to those of the coupling portion 35. At the other end, a mounting hole for fitting a cylindrical member 10 therein is formed, wherein the cylindrical member 10 is fitted and held by an interlocking cable 6 to be interlocked with an operating portion 5 for the automatic transmission. Thus, the holder 7 is detachably attached to the coupling portion 35 by screwing a nut 12 onto a fixing screw 11 passing through the respective through holes of the coupling portion 35 and the holder 7.

Title: Method for processing surface of electrically conductive substrate for electrophotographic sensitive body
Inventor: MIYATA KOUJIROU
IPC: G03G5/10
Filed: 1990-10-11
Abstract: PURPOSE:To execute both processes of the roughing and the cleaning of a surface at the same time, to uniformize the degree of surface roughness and to eliminate a remaining substance by processing the surface of an electrical conductive substrate by using a rotating brush having rigidity and solvent for cleaning by a centerless system. CONSTITUTION:The rotating brushes 2 and 3 are rotated in a direction shown by an arrow by making the rotational speed thereof different. By the difference between the rotational speed, rotating force is given to the cylindrical electrical conductive substrate 5 and the substrate 5 is rubbed while it is rotated in the direction shown by the arrow. Then, the brushing thereof is executed. At this time, since the lower parts of the brushes 2 and 3 are immersed in the solvent for cleaning 4, Al powder or the like left on the surface of the substrate 5 is made to drop in the solvent 4 by the rotation and the roughing and the cleaning are executed at the same time. Then, a brush obtained by planting synthetic fiber such as nylon on a cylindrical body can be used for the brushes 2 and 3 and the group of halogenated hydrocarbon can be used for the solvent 4.

Abstract: PROBLEM TO BE SOLVED: To obtain an alkylhydrazine salt on an industrial scale in a high yield and in a high purity by allowing hydrazine to react with an alkene and water in the presence of a strong protonic acid.  
     SOLUTION: This method for producing an alkylhydrazine salt of formula II (X is the anion of a strong protonic acid) comprises vigorously stirring hydrazine, a protonic acid and an alkene of formula I (R 1  is a 1-4C alkyl; R 2  is a 1-4C alkyl, a 2-4C alkenyl, a 2-4C alkynyl or phenyl; R 3  and R 4  are each H, a 1-4C alkyl, a 2-4C alkenyl or a 2-4C alkynyl, or a pair of R 1  and R 2  or a pair of R 3  and R 4  each form a 5-8C cycloalkyl together with C) in a reactor at 75-150°C and subsequently cooling the reaction product up to a temperature of ≤60°C. Water serves as a solvent and is added in the form of hyrazine hydrate, an aqueous protonic acid and/or water itself. The hydrazine and the protonic acid are again added to the mother solution, and the alkene is again added to recycle the materials. The alkylhydrazine is useful as an intermediate for medicines or crop-protecting agents and so on.

Abstract: PROBLEM TO BE SOLVED: To prevent the deformation and damage of a side wall even in the case of large torque being repeatedly applied to the tooth surface by arranging ribs radially along lines connecting both ends of the ribs to tooth roots of a tooth profile and the axis of a hub, integrally with the side wall. SOLUTION: Ribs 6 (6a-6f) are provided integrally with a side wall 5 and radially arranged along lines connecting tooth roots 2a of a tooth profile 2 to the axis of the hub 4, and both ends of the ribs 6 are respectrively connected to a rim 3 and a hub 4. In case force acts tangentially upon the tooth surface of a molded gear 1 and this force acts upon the tooth surface of the tooth profile positioned near a part provided with the rib 6, this force is transmitted to the rib 6, but since the width of the rib 6 is the same as the width of the tooth surface, and the side wall 5 provided at the center part of the ribs 6 also has the same thickness as the width of the tooth surface, the side wall 5 is not deformed.  In case force acts upon the tooth surface of the tooth profile positioned at an intermediate part between the ribs 6, since the adjacent ribs 6, the rim 3, the hub 4 and the side wall 5 form grated shape that is not easily deformed. Deformation and damage are not therefore generated.

Abstract: PURPOSE:To improve anti-jamming performance by providing means for calculating inner product of angular differential vector and output vector from an angular speed calculating means for each region of an image, thereby, making a target distinguishable from a decoy even if they are close to each other. CONSTITUTION:An imaging unit 1 is fixed to a servo base 2 and directs the optical axis in an arbitrary direction. An inner product calculating means 11 receives a decision result from a centroid evaluating means and calculates the inner product of an output vector from an angular speed calculating means 13 and a centroid vector outputted from a centroid measuring means 6 for every region and decided to be valid. A maximum value selecting means 12 selects a centroid vector for a region having maximum inner product and outputs the centroid vector thus selected. A prediction filter 7 predicts a next time target centroid vector basing on a centroid vector provided from the selecting means 12 and an attitude angular speed vector of fuselage provided from an angular speed sensor 4. Prediction results are fed to an evaluating means 8 where next time order is determined while furthermore the prediction results are fed to the base 2 which is then controlled to direct the imaging unit 1 toward a target.
