Abstract: An Fe—Mo—Cu—C-based alloy steel powder for powder metallurgy has a chemical composition containing Mo: 0.2 mass % to 1.5 mass %, Cu: 0.5 mass % to 4.0 mass %, and C: 0.1 mass % to 1.0 mass %, with a balance being Fe and incidental impurities, wherein an iron-based powder has a mean particle size of 30 ?m to 120 ?m, and a Cu powder has a mean particle size of 25 ?m or less. Despite the alloy steel powder for powder metallurgy having a chemical composition not containing Ni, a part produced by sintering a press formed part of the powder and further carburizing-quenching-tempering the sintered part has mechanical properties of at least as high tensile strength, toughness, and sintered density as a Ni-added part.

Abstract: The present invention relates to a heater including a heating element of which a main component is V, Nb, Ta, Mo, or W, leads bonded to respective ends of the heating element, and an insulating base in which the heating element and the lead are embedded, in which the heating element and the insulating base are formed of a sintered body which is integrally sintered, the heating element includes a compound including at least one of V, Nb, Ta, Cr, Mo, W, Mn, or Fe, which is an element different from the element used as the main component of the heating element, and the element is substantially not included around the heating element in the insulating base.

Abstract: A heater includes a heating element, a pair of lead wires each connected to an end of the heating element, and an insulating base body in which the heating element and the pair of lead wires are embedded. The insulating base body contains a plurality of metal particles around the heating element, the metal particles being separated from the heating element. The plurality of metal particles and the heating element comprise an elliptical cross-section comprising a same major axis direction. With such a structure, when the heater is rapidly cooled to cause a crack on the surface of the insulating base body, the crack develops along the major axis direction of the metal particles and therefore rarely reaches the heating element. This resists breakage of the heating element.

Abstract: A ceramic heater of the invention includes a ceramic structure; a heat-generating resistor embedded in the ceramic structure; and a feeder line embedded in the ceramic structure so as to be connected, at one end thereof, to the heat-generating resistor. The feeder line is made of metal, and metal grains of a center region of the feeder line are greater in grain size than metal grains of an outer periphery region of the feeder line. Even if a crack developed in the outer periphery region of the feeder line propagates through grain boundaries in the outer periphery region and comes near the center region, propagation of the crack through the interior of the center region can be suppressed.

Abstract: A fluid feed pump is configured, such that a fluid is fed from an outlet channel of the fluid feed pump through an outlet buffer chamber to a fluid channel. The outlet buffer chamber is designed to have a higher compliance than a compliance of a pump chamber. The driving period of the fluid feed pump is set to a shorter period than a time constant defined by the compliance of the pump chamber and a flow resistance between an inlet of the outlet channel and an outlet of the fluid channel. This enables the fluid to be fed with high efficiency by taking advantage of the pressure oscillation occurring between the pump chamber and the outlet buffer chamber.

Abstract: It is a subject of this invention to isolate a gene group of enzymes involved in the biosynthesis of vitamin E of Para rubber tree, and to determine the base sequence of each gene. According to this invention, genes encoding enzymes involved in the vitamin E biosynthesis were isolated from Para rubber tree and the base sequences of these genes were determined. Since vitamin E is an antioxidant existing in nature, it is expected that transformation of a plant by using the genes obtained in the invention would result in an increase in the vitamin E content of the plant and, in its turn, contribute to the prevention of rubber from aging.
