A stator core comprises a circumferentially deformable part formed on a radially outer peripheral side of a yoke; circumferentially facing divided parts formed on a radially inner peripheral side of the yoke, each having a dividing line that is oriented in a radial direction and reaches a portion between teeth and divided surfaces that face each other without a gap; and radially facing divided parts formed at the center between the radially inner and outer sides of the yoke along the circumferential direction at the predetermined interval, and each having divided surfaces that face each other in the radial direction, and being continuous at one ends with the respective circumferentially facing divided parts. The circumferentially facing divided parts each have a compressive stress being smaller than a compressive stress acting on the circumferentially deformable part or being zero.

Stator core of motor, and manufacturing method

A valve spring device is provided with a first coil spring and a second coil spring combined in series with each other. The inside diameter (coil inside diameter) of the second coil spring is greater than the outside diameter (coil outside diameter) of the first coil spring. A part of the first coil spring including an end portion along an axis is inserted into the second coil spring, thereby forming a combined spring. The end portion of the first coil spring and an end portion of the second coil spring are connected to each other by a connecting member. The first and second coil springs are compressed along the axis as they are located in series between a cylinder head and a retainer. A shaft of a valve is passed within the coil springs.

A damper spring device is provided with a first spring and a second spring retained by a stopper in such a manner that the second spring is compressed by a preload. The preload on the second spring is greater than a preload on the first spring. The first spring and the second spring have load-deflection characteristics such that the first spring deforms when an axial load acting in the direction of compression of the first spring is not greater than a load at which a strand of the first spring is at least partially compacted and that the first spring and the second spring deform when the axial load is greater than the load at which the strand of the first spring is at least partially compacted.

A port is formed in a cylinder head of an engine. The port is opened and closed by a valve. A valve spring device is provided with a first spring and a second spring. The second spring is contained in a housing and held by a stopper in a manner such that it is compressed along an axis or subjected to a preload. The preload of the second spring is larger than an installation load of the first spring. An axial load acts on the springs. The valve spring device has load-deflection characteristics such that only the first spring deforms axially when the axial load is not larger than a predetermined value and that both the first and second springs deform axially when the axial is load exceeds the predetermined value.

A liquid discharge apparatus for aligning needle-like structures. The apparatus includes a tapered nozzle having an entrance and a discharge opening. The nozzle is tapered in such a manner that its diameter decreases towards the discharge opening. The diameter of the nozzle at the entrance is larger than the length of the needle-like structures, and the diameter of the discharge opening is larger than the diameter of the needle-like structures and smaller than the length of the needle-like structures. By passing through the nozzle, the needle-like structures are aligned.

A bellows unit and a compression coil spring are located in series with each other between a first member and a second member. The bellows unit has an inner bellows, an outer bellows, and first and second end members. A sealed space is defined in the bellows unit. A compressed gas is sealed in the sealed space. The bellows unit is caused to extend and contract in the direction of an axis by the compressed gas. The sealed space contains an uncompressible liquid that can exchange heat with the gas. The liquid is an example of a heat exchange material.

Disclosed is a system, for exchanging data among a plurality of devices, wherein a device can detect the state of another device without that device being powered on, and whereby usability can be enhanced. According to the system, during data communication a power supply device supplies power to a power reception device, and activates sections necessary for the power reception device. The state of the power reception device is detected by a power management unit, and the information that is obtained is transmitted across a data I/F unit to the power supply device, and stored in a storage unit. Based on the stored status information, the supply of power to the power reception device can be controlled.

An ink container includes a cylindrical member having a closed end and an opposite open end; and a flexible member covering the open end of the cylindrical member to define an ink containing portion. The flexible member has a bottom portion and a bent portion that is movable along an internal surface of the cylindrical member with consumption of the ink therein, wherein the bottom portion is less easily deformable than the bent portion and movement of the bent portion is irreversible.
