A sliding component 10 slidably supporting an object includes a non-conductive first sliding part 1 with a sliding surface making contact with the object and a conductive member 2 provided in the first sliding part 1 or on a side opposite to the sliding surface of the first sliding part. Wear of the first sliding part 1 is detected by detecting a conduction state in the conductive member 2.

A controller of a motor controller operates to perform a process including: controlling the H bridge circuit to switch to the charge mode; controlling the H bridge circuit to switch to the high-dissipation mode when the zero-cross detector detects that the back electromotive force voltage of the motor coil connected to a phase of the H bridge circuit shortly before the H bridge circuit is zero-crossed; controlling the H bridge circuit to switch to the low-dissipation mode after a predetermined time has elapsed; and controlling the H bridge circuit to switch to the free mode when the voltage detector detects that the differential voltage between the motor coils connected to the H bridge circuit is lower than a predetermined voltage.


There is provided a thermosetting resin composition including: an epoxy compound having an isocyanuric acid ring represented by the following formula (1); a solid lubricant; and a diisocyanate compound, or the diisocyanate compound and a bismaleimide compound.

Minebea Co. | Date: 2016-03-29

There is provided a track roller bearing. The track roller bearing comprises: an inner ring, an outer ring concentric and rotatable relative to the inner ring; a resin liner formed on at least one of an outer circumferential surface of the inner ring and an inner circumferential surface of the outer ring; and an opposite surface which slides on a liner sliding surface of the resin liner. A non-contact portion is formed in an area in which the resin liner is formed, the non-contact portion being a portion in which the liner sliding surface does not contact the opposite surface.

There is provided a rolling bearing including: inner and outer members, rolling elements in a raceway space, flexible annular sealing members which close openings at both ends of the raceway space, and annular metal shield members. Each sealing member is formed in three-dimensional shape such that the sealing member in a natural state is convex inwardly between outer and inner circumferential edge portions and the inner circumferential edge portion is elastically in surface contact with the outer surface of the inner member when the sealing member is fitted to the outer member. Each metal shield member is fixed to the outer member in a state that the outer circumferential edge portion of each sealing member is sandwiched between the metal shield member and the outer member. Each metal shield member covers part of each sealing member without contacting the inner member.

There is provided a tilting mechanism. The tilting mechanism includes a drive source configured to drive a plate, a movement unit connected to the drive source, a conveyance unit configured to be moved linearly by the movement unit, and a plate support member to which the plate is fixed and which is partially engaged with the conveyance unit so that the plate support member is moved by the conveyance unit. The plate is moved linearly by linearly moving the conveyance unit together with the plate support member. Tilting operation of the plate is performed by tilting the plate support member, the tilting of the plate support member being caused by pushing the plate support member by the conveyance unit, which moves linearly in a state that the linear movement of the plate support member is stopped.
