A manufacturing device for a stator of a rotating electrical machine includes a jig, a support section, link mechanisms and press sections. The jig has holding grooves into which linear portions of coils can be respectively inserted. The jig can be arranged on the inner side of a stator core while holding grooves respectively face the openings of slots. Each of the link mechanisms has a push-out member and a link. The link moves a corresponding push-out member in a direction from the bottom portion of the holding groove to a corresponding slot and in a direction from the slot to the bottom portion. The push-out members can concurrently apply a pressing force to all the coil ends of the coils from the axial direction of the stator core in synchronization with the link mechanisms.

A compressor includes a drive shaft, a housing, an annular rotor, and cradles. The rotor has cradle windows. The rotor can rotate within the rotor chamber together with the drive shaft while being in sliding contact with the housing at the circumferential surface. The cradles are provided in the cradle windows to be pivotable about pivot axes. When pivoting, the cradles maintain the compression chambers in an airtight state by being in contact with the housing at pivoting ends of the cradles, the pivoting ends extending along the direction parallel to the axis. The rotor chamber includes an outer operation chamber located on the outside of the rotor, and an inner operation chamber located on the inside of the rotor. The cradles, and the outer operation chamber and/or the inner operation chamber form the compression chambers, the volumes of which are varied by the rotation of the rotor.

Disclosed is a stator for a rotating electrical machine, which includes a stator core having a plurality of slots, and a plurality of coils. Each of the coils has a first inserting section and a second inserting section, which are inserted into two slots which form a pair, a first coil end, and a second coil end. The first and/or the second coil end has a twisted portion and a bent portion. The twisted portion is formed by twisting the coil end at a part close to the first inserting section. The bent portion is formed by bending, at a part close to the second inserting section, the coil end such that the coil end is laid flat.

In an injection apparatus, a first cylinder and second cylinder for driving an injection cylinder connected to an injection plunger are connected in parallel with each other with respect to the injection cylinder. A piston of the first cylinder and a piston of the second cylinder are synchronously driven by driving means. A directional control valve and first flow rate adjustment circuit are provided between one end of the injection cylinder and one end of the first cylinder. Moreover, second flow rate adjustment circuit is provided between the other end of the injection cylinder and the other ends of the first and second cylinders.

Injection apparatus

An injection apparatus includes a pressure accumulating portion, which is connected to an injection cylinder, and a speed reduction mechanism, which reduces the speed of the injection cylinder arranged in the injection apparatus. The speed reduction mechanism includes an actuating member, which moves integrally with a rod of an injection cylinder rod, and a restriction member, which is arranged in a flow passage for draining or supplying hydraulic oil from or to the injection cylinder, and variably narrows the flow passage in conjunction with movement of the actuating member.

The injection apparatus, which injects a molding material into a mold by operating an injection cylinder and fills the mold with the molding material, includes a plurality of actuating mechanisms that is connected to the injection cylinder. Each actuating mechanism includes an actuating cylinder that supplies an incompressible fluid to the injection cylinder, and a drive part that drives a piston of the actuating cylinder. In a low-speed step and a high-speed step for injecting the molding material, the piston of each actuating cylinder is driven forward, and hydraulic oil is supplied to the injection cylinder. In a pressure-increasing step, the pistons of the actuating cylinders are driven forward, and hydraulic oil is supplied to the injection cylinder. As the injection apparatus includes a plurality of actuating mechanisms, the speed and pressure of the injection cylinder can be increased without requiring high performance from the drive parts.

The mold clamping device is provided with a first platen to which a stationary mold is attached. A movable mold unit is capable of approaching and moving away from the stationary mold. A second platen is linked to the first platen via a tie bar. When the movable mold unit and the stationary mold are closed, a wedge member is driven onto the movable mold unit to generate mold clamping force. The second platen has a pressure receiving surface. The pressure receiving surface receives, through the wedge member, mold opening force that is generated by filling, with a molding material, the stationary mold and the movable mold unit that are in the closed state.

An assembling apparatus () comprises a shaft member () having a linear assembling function and a rotational assembling function, a base () supporting the shaft member () to be movable in the axial direction and rotatable axially, and a drive unit moving in an axial direction and axially rotating the shaft member ().

Assembling apparatus

The injection apparatus is provided with a high speed step cylinder, a pressure accumulation part and a coupling mechanism. The high speed step cylinder has a rod and an operating chamber. The coupling mechanism is capable of switching between a coupled state in which the movement of the rod is restricted, and a non-coupled state in which the coupled state is released so as to enable the rod to move due to the operating pressure. The coupling mechanism includes a first coupling member, a second coupling member and a drive source. The coupling mechanism is kept in the coupled state in which the second coupling member is rotated to less than 90&#xb0;. When the second coupling member is forced to rotate in the coupled state, the first coupling member rotates such that a first contact surface is in contact with a second contact surface.

An injection apparatus includes an actuating cylinder, an accommodating chamber, and a volume changing part capable of changing the volume of the accommodating chamber. The actuating cylinder has an operation chamber and a piston accommodated in the operation chamber, and supplies an incompressible fluid to the injection cylinder by forcing out the incompressible fluid inside the operation chamber with the piston. The accommodating chamber is connected to the operation chamber, and holds at least some of the incompressible fluid that flows out from the operation chamber due to the piston being pushed out. The volume changing part expands the volume of the accommodating chamber, at the latest simultaneously with the start of acceleration of the actuating cylinder, and stops the expansion of the volume when the operating speed of the piston of the actuating cylinder has reached a desired speed.
