Title: Mandrel
Inventor: KITAMI SATORU
IPC: B29C53/82
Filed: 1992-01-16
Abstract: PURPOSE:To obtain a mandrel having proper flexibility, heat resistance, dimensional stability, surface hardness and rigidity. CONSTITUTION:The mandrel is made such that a resin composite is extrusion- molded into a rod shape, which contains 10-50 pts.wt. maleic acid anhydride denaturated EPDM and 0-20 pts.wt. sulfonic amide plasticizer with respect to 100 pts.wt. nylon resin. The mandrel is characterized that after a part of the nylon resin and sulfonic amide plasticizer are kneaded so as to be a plasticized nylon, a resin composite fusionally kneaded by adding the remainder is subjected to extrusion molding for making it into a rod shape. By employing these mandrels, hoses formed with polyamide resin in its pipe inner layer are readily manufactured with stable quality, such as a fuel transportation hose, a low gas permeable hose, a pressure resistive hose and so on.

Title: Method and device for soldering circuit board
Inventor: PIITAA MITSUSHIERU BANKUSU
IPC: B23K1/08
Filed: 1993-01-18
Abstract: PURPOSE: To form an extremely uniform height of solder on the pads of a circuit board by having the circuit board pass through a solder bath, while rotating it along a path which is substantially coplanar with the circuit board. CONSTITUTION: Molten solder 3 is put into a solder bath 1. A layer 5 of oil, such as polyoxyalkyleneglycolether exists on the solder 3. Oxidation of the molten solder and the formation of molten metal scraps are prevented by the layer 5 of coil. A circuit board 7 to be coated is attached on a titanium carrier 9. The carrier is supported in turn by a shaft 11. The shaft 11 may be rotated by a motor. The height of the shaft 11 is adjustable and a motor speed, i.e., the rotational rate of the shaft 11 is also controllable. Therefore, the solder having the uniform height is obtained on the pads of the circuit board by dipping the circuit board 7 into the solder 2, so as to pass the circuit board 7 through the solder bath 1 while rotating it along a path which is substantially coplanar with the circuit board 7.

SOLUTION: A stator core 45 is formed of tooth parts 46 and 47 which surrounds the outer circumference of a rotor 41 and used as a pair of poles, and an arm unit 51. If an angle between the tangential direction of the inner wall of the tooth part 46 and the inner wall of the arm unit 51 at a contact point P, where the inner wall of a tooth part 46 is brought into contact with the inner wall of the arm unit 51 is defined as an arm unit attachment angle θp to, by getting the angle θp be not larger than 100 deg., a magnetic constriction part 49 is formed in the neighborhood of the connection part of the outer circumference of the tooth part 46 and the arm unit 51.  Therefore, since a flux which passes through the tooth part 46 from the front part of the tooth part 46 are pushed into the tangential direction of the inner wall of the tooth part 46, a flux directed from a permanent magnet 43a towards the rear edge of the tooth part 46 diagonally crosses a gap between the inner wall of the tooth part 46 and the permanent magnet 43a, in a direction close to the tangential direction of the inner wall of the tooth part 46 and a torque generated in the later period of rotation is increased.

Abstract: PURPOSE: To effectively prevent the movement of the cylindrical bodies in the axial direction in a simple structure, by preventing the longitudinal movement by using fixed stoppers and the parts of the auxiliary stoppers which are not contacted with the bottom surfaces of the cylindrical bodies. The rest of the auxiliary stoppers is always contacted with the bottom surfaces of the cylindrical bodies by the upward force.  
     CONSTITUTION: The cylindrical bodies 10a and 10b are placed on a load support 7 of an axial movement preventing drvice 6. The cylindrical bodies 10a and 10b are contacted with load supporting parts 7a and 7b, and the movement and rolling are blocked. Unit stoppers 12 of the auxiliary stopper 9 in contact with the cylindrical bodies 10a and 10b descend against the force of a coil spring 13. While the  unit stoppers 12 which are not in contact with the cylindrical bodies 10a and 10b are in the protruded state, and the distances l 1  and l 2  are formed between the stoppers and the end surfaces of the cylindrical bodies. Even though the cylindrical bodies are moved by the external force, they are contacted with the unit stoppers 12 after the movement of l 1  and l 2 . Since said unit stoppers 12 are supported by the fixed stoppers 8, further movement of the cylindrical bodies is restricted.
