An electric motor includes a cylindrical yoke with a bottom; a bracket that covers an opening of the yoke; and a brush holder. The brush holder includes a brush housing portion, with the brush housing portion having three side piece portions, excluding a bottom piece portion, integrally formed; a first disk portion; and a second disk portion. The first disk portion and the second disk portion are integrated with the bottom piece portion of the brush housing portion. A ring-shaped abutting surface and the bottom piece portion of the brush housing portion are formed on a bracket-side disk surface of the brush holder. The abutting surface is formed as a holding portion that is pressed to the yoke by the bracket via a bracket-side elastic member.

A fluid ejection device ejecting a fluid, the fluid ejection device includes: a fluid ejection unit, a main chassis case, a fluid-containing pack, and a container case. The fluid ejection unit ejects a fluid onto an ejection target. The main chassis case houses the fluid ejection unit. The fluid-containing pack contains a fluid for ejection. The container case houses the fluid-containing pack. The container case is pivotably attached to the main chassis case and openable by rotation about a rotation shaft.

A superconducting magnet includes: a superconducting coil for generating a static magnetic field; a refrigerant container for containing the superconducting coil and a refrigerant; a vacuum container for holding the refrigerant container in a vacuum state; a radiation shield between the refrigerant container and the vacuum container; a refrigerator for re-liquidfying the refrigerant; and a dynamic magnetic field shield. The refrigerator includes: first and second regenerative refrigerants. The dynamic magnetic field shield is an electric good conductor and arranged around the first regenerative refrigerant along a motion axis of the first regenerative refrigerant, wherein a direction of the motion axis is aligned with a direction of a magnetic force line of the static magnetic field at the first regenerative refrigerant.

A magnet device has main coils in a pair positioned facing each other to form a static magnetic field space in between and external magnetic flux shielding coils placed coaxially to the main coils. The external magnetic flux shielding coils have a first coil group having a small coefficient of coil coupling and a second coil group having a coefficient of coil coupling greater than that of the first coil group. The first coil group is connected in series to the second coil group. External magnetic flux entering the magnetic field imaging space formed by main coils in a pair positioned facing each other is effectively warded off.

Disclosed is an industrial endoscope system having a rotary treatment member, attached to a hard top part at a distal end of an insertion unit, for effecting a treatment such as grinding by rotating this treatment member itself. The system includes a moving means for making a distal end of the treatment member movable in the axial directions of the insertion unit. This easily leads the treatment member to a target position via a lead-in port of an engine; or the treatment member can be set in a position suitable for the treatment.

A gasket including a sheet having a composition of 40 to 80% by weight of thin flakes of expanded vermiculite, 1 to 30% by weight of fibers, 5 to 40% by weight of fine filling grains, and appropriate amounts of a binding agent and a vulcanizing agent. The sheet also has a metal plate laminated thereto. A vortex gasket may be formed by spirally winding a metal hoop together with a filling material, which is composed primarily of expanded vermiculite.
