Abstract: The present invention provides a bending device which is capable of easily controlling a bending motion with superior controllability. A portion of an elastic tube body (11) opposite a portion in which a non-stretching body (4) is fixed inflates in a circumferential direction of the elastic tube body (11) in response to increase in an internal pressure of the elastic tube body (11), and an elastic tube (1P) bends in a step-wise angle corresponding to the number of layers of a multi-layer structure. The portion of the elastic tube body (11) in which the non-stretching body (4) is fixed is thicker than the remaining portion of the elastic tube body (11).

Abstract: According to the present invention, film-shaped insulating materials (32) are provided in core slots (12), the insulating materials being extended by a specific dimension from the ends of outer peripheral cores (17) and inner peripheral cores (18) of core segments (11) to the outsides of the cores, and the plurality of core segments (11) are separated and held at specific intervals, so that winding can be continuously performed on split cores while a winding capability is maintained. Further, the core segments (11) are brought close to one another and rounded to form an annular shape while the film-shaped insulating materials (32) extended by the specific dimension to the outsides of the core are sequentially bent, so that it is possible to manufacture a stator ensuring an insulation distance between an exciting coil and the core and interphase insulation between out-of-phase coils.

Abstract: In a stator for an electric motor, insulating members are formed on laminated iron cores divided for each pole-tooth unit in the direction of the output shaft and windings are applied perpendicularly to the pole-tooth portions in a high-density alignment. After a predetermined number of the laminated iron cores are combined so as to form a cylindrical configuration, they are welded at the outer end portions of the dividing surfaces in the direction of lamination so as to construct an integral structure stator with rigidity, thereby enabling high densification of the windings (conductor space factor of 70%) and space-savings in the winding end portions. Further, as any joint portions between the pole-tooth portions are not necessary, reduction (5 to 10%) in motor efficiency due to such joint portions can be prevented, and, as any integrally forming by resinous members is not necessary, inter-winding short-circuiting is not caused. Welding may be replaced by adhesive bonding.

Abstract: A plurality of vane chambers on the back side of vanes are caused to function as pump chambers using the reciprocating movement of the vanes to pressure-feed a lubricating oil to a compressor mechanism unit. A taper hole at one of the vane chambers for drawing the lubricating oil, a hole on another chamber for mitigating back pressure and a taper hole between the chambers are provided to improve the pressure feeding capability. In addition, the lubricating oil having been supplied to the compressor mechanism unit is supplied to the slide surfaces of crank portions from an oil hole of each crank portion through an oil passage at the center of the rotating shaft and is further distributed optimally to slide bearing portions by oil guide grooves.
