摘要： A sintered bearing is made of a sintered compact containing nickel silver (Cu—Ni—Zn) as a base. In the sintered bearing, P is not added in the sintered compact. Alternatively, a content of P in the sintered compact is less than 0.05 mass % in terms of mass ratio to a total mass. Consequently, crystal grains constituting the sintered compact can be micronized. In particular, in the sintered bearing, an average crystal particle diameter of the crystal grains constituting the sintered compact is 20 μm or less. Consequently, the mechanical strength and the vibration resisting properties can be improved, and the rotation shaft can be prevented from being damaged.

摘要： The present disclosure provides a method for manufacturing a heat exchanger including an evaporating body configured to absorb heat from outside and evaporate a liquid-phase working fluid into a gas phase while moving the working fluid by capillary forces. The method includes steps of: forming a recess in a plate surface of a first plate member, the first plate member being plate-shaped; applying a powder-containing material to a predetermined region in the recess; solidifying the material applied to the predetermined region to form the evaporating body; and covering the recess having the evaporating body formed thereon with a second plate member, the second plate member being plate-shaped, and securing the first plate member to the second plate member.

摘要： A method for manufacturing a wick includes: supplying material powder containing metal powder onto a base; heating the material powder on the base to obtain a sintered compact; and rolling the sintered compact. In this situation, when the material powder supplied onto the base is heated to form the sintered compact, the sheet-shaped sintered compact can be formed. Further, when the sintered compact is rolled, a void ratio of the sintered compact can be controlled after forming the sintered compact, thereby controlling the capillarity of the wick.

摘要： Provided is a method for manufacturing a wick, which facilitates control over capillarity of the wick. A method for manufacturing a wick according to the present invention includes: a step of supplying material powder containing metal powder onto a base; a step of heating the material powder on the base to obtain a sintered compact; and a step of rolling the sintered compact. In this situation, when the material powder supplied onto the base is heated to form the sintered compact, the sheet-shaped sintered compact can be formed. Further, when the sintered compact is rolled, a void ratio of the sintered compact can be controlled after forming the sintered compact, thereby controlling the capillarity of the wick 1.
