Title: Brush unit for small-sized motor
Inventor: HONDA YUKIO
IPC: H02K13/00
Filed: 1993-10-04
Abstract: PURPOSE:To provide a small-sized motor, cost of which is reduced and vibrations of which can be damped and which has a brush, by using a constraint material constituting a vibration-damping sheet by bending a brush material as a vibration-damping sheet arranged for lowering vibrations generated in the brush and disposing a viscoelastic body between the constraint material and the bush in a motor with the metallic brush employed for OA and domestic electric fields, etc. CONSTITUTION:A section between brushes 3 which have been punched by a press is bent in the direction of a brush fixing section 1 without punching and used as a constraint layer. The constraint sections 3 and the brushes 2 are bonded and fastened by viscoelastic bodies 4. According to such constitution, the constraint sections 3 configured by bending the brushes are difficult to be deformed, thus constraining deformation in the direction that deformation is inhibited. The viscoelastic bodies 4 are deformed at that time, thus converting vibrations into heat, then effectively damping vibrations.

Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To transform the central projected image of a two-dimensional object which freely moves in a three-dimensional space obtained from a certain visual point into a central projected image obtained from a designated visual point. SOLUTION: A quadratic curve (7 or more points) in the central projected image of a two-dimensional object is detected and expressed in the form of a six-dimensional vector. A quadratic curve transformation matrix which indicates the transformation of the quadratic curve is found by giving the six- dimensional vector which designates the point into which the quadratic curve is to be transformed in a central projected image obtained from a designated visual point. From the matrix, the transformation matrix indicating the transformation between a given central projected image and the central projected image obtained from the designated visual point is uniquely found by performing linear calculation. The points and segments indicating the object in the central projected image are transformed into the image obtained from the designated visual point based on the transformation matrix.

Title: Manufacture of surface mounting type reed switch
Inventor: KONDO KOICHI
IPC: H01H11/00
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To manufacture a surface mounting type reed switch in proper workability, by applying bending working to a portion, protruded from a glass tube and squeezingly worked already out of terminal members after the glass tube is sealed. SOLUTION: A heat-treated terminal member 40 is heated and cooled to remove work hardening caused in a strip part 25 to obtain a heat treated member 41. Then two heat treated terminal members 41 are arranged in a straight line state to be positioned in a state that the tips of reed contact parts 20 are faced, to seal both the end sides of a glass tube 23 to the member 41. Consequently, the contact parts 20 are enclosed in the tube 23 to make a state that an estimated terminal portion 22A is protruded outside than the tube 23. Finally a heat-treated strip part 25A is bent into a crank state by using a presser, thereby a terminal 26A is formed to complete a surface mounting type reed switch 27A. Here, since the strip part 25A is in a state that work hardening due to press working is removed, a load, applied by the presser, may be lower than before.

Title: Manufacture of gas diffusing electrode for fuel battery
Inventor: SAKURAI MASAHIRO
IPC: H01M4/88
Filed: 1985-11-07
Abstract: PURPOSE:To maintain a thin film of electrolytic liquid on the surfaces of catalytic particles stably for a long time so as to prevent reaction gas dissolution and moving resistance increase, by letting fluororesin of 20-30wt% with respect to the catalytic powder weight adhere to the powder before making catalytic layer. CONSTITUTION:In an electrode with a porous electrode base material on which a catalytic layer composed of uniformly mixed body to precious metal holding carbon catalytic powder and fluororesin is formed, fluororesin of 20-30wt% with respect to the weight of the precious metal holding carbon catalytic powder is made to adhere to the powder beforehand. When water repellent treatment is applied to the catalytic particles with the fluororesin, if the amount that should be treated is large, since the water repellency of the catalytic powder becomes large and the catalytic active sites are covered by the fluororesin, the value of electrochemical specific area of the catalyst in the electrode catalytic layer becomes small. On the other hand, in the case where the water repellent treatment of the catalytic particles is insufficient, since the water repellency of the catalytic powder is small, the electrolytic liquid easily infiltrates into catalytic particle lumps and the lumps are leaked, resulting in reaction gas dissolution and moving resistance increase.
