Abstract: A shield member electromagnetically shielding at least part of an electric circuit has a first end and a second end. The first end is configured to be constantly connected to a ground wire to electromagnetically shield at least part of the electric circuit; and the second end is configured to be selectively connectable to a power source, the shield member being configured to generate heat when energized while the second end is connected to the power source. Accordingly, the shield member electromagnetically shielding at least the part of the electric circuit can serve as a heater for preventing freezing and snow attachment.

Abstract: A thrust bearing is equipped with a resin coating applied to the surface of a base material. Lattice-shaped discharge grooves are formed in the surface of the thrust bearing, and planer protrusions having a square shape or the like are formed at the adjacent positions thereof. Each corner part of each planer protrusion form a sliding surface that slides with respect to a counterpart member. Contaminants such as wear particles that have infiltrated between the counterpart member and the sliding surface fail into the discharge grooves and then are discharged outside of the sliding surface. The chamfering of each corner part to a rounded shape prevents the contaminants from accumulating in the discharge grooves, thus preventing the contaminants from biting into the planer protrusions.

Abstract: A hemispherical shoe 4 is equipped with a sliding surface 4A which slides with a swash plate 3, and a hemispherical convex 4B. Hardening is performed by radiating a laser so that minute circles 6 may be drawn on the sliding surface 4A. Then, lapping is given to the sliding surface 4A and, finally, buffing is given thereto. Thereby, the annular swelling portions 7? and concavities 8? are formed in positions of the circles 6 and, further, lubricating oil passages 10? which include net-like concavities are formed in the sliding surface 4A. A hardening part is formed of the above-mentioned annular swelling portions 7?. The above-mentioned annular swelling portions 7? are formed so that a ratio of an area of a total of all the above-described annular swelling portions 7? occupying an area of the sliding surface 4A which is a hardening object domain may become 0.3 to 0.8. It is possible to provide a shoe 4 which is good in seizure resistance in comparison with the past.

Abstract: A hemispherical shoe (sliding member) 1 has a flat sliding surface 3, which is quenched to form a quenched portion 7. A part of the quenched sliding surface is partially annealed to form an annealed portion 6. When an oil film pressure acts on the sliding surface 1, the annealed portion 6 is deformed by pressure so that the surface thereof has a concave portion 6A. In the annealed portion 6, a remaining quenched portion 8 may remain at the center part thereof. The concave portion 6A can be used as an oil reservoir or an oil flow path, so that an excellent seizure resistance can be ensured.
