Abstract: An oil supply structure includes an oil passage that provides communication from a wall portion of a casing, which corresponds to a shaft end portion of a rotary shaft pivotally supported in the casing to the shaft end portion of the rotary shaft. The oil passage includes a shaft end oil passage and an in-shaft oil passage. The shaft end oil passage is provided on a shaft end portion side of the rotary shaft. The in-shaft oil passage is provided in the rotary shaft, and extends an axial direction of the rotary shaft from the shaft end oil passage. A flow rate adjusting member is provided to the shaft end oil passage, and adjusts lubricating oil which flows from the shaft end oil passage to the in-shaft oil passage.

Abstract: Provided is a frictional engagement device including outer and inner base bodies, outer and inner friction plates, a piston, a return spring, and a spring seat. Sliding grooves which guide sliding movement of the outer or inner friction plate in the axial direction are provided in at least one of the outer and inner base bodies at intervals in a circumferential direction, the outer or inner friction plate which slides in the sliding grooves includes protruding pieces fitted in the sliding grooves, a spring seat which is located on one end portion of each of the sliding grooves and supports one end of the return spring is provided on the outer or inner base body in which the sliding grooves are provided, and a through-hole which communicates with the sliding grooves and is capable of discharging lubricating oil that has accumulated in the sliding grooves is provided in the spring seat.

Abstract: A method of manufacturing an anode copper ball for plating by forging in an oilless state, and to minimize flat portions existing on the surface of the ball to improve the rolling property of the ball. Manufacturing an anode copper ball for plating which forms a ball by subjecting a copper rod to cold multi-stage forging by a metal mold composed of a plurality of sets of dies and punches. The method includes a first forging step of forging the copper rod in a direction of its axis without being brought into pressure contact with an inner wall surface of the die, to thereby form a first intermediate material in which outer peripheral portions of end faces of the copper rod are pressed and formed as tapered faces. The first intermediate material is formed in the shape of a ball through the first forging step.

Abstract: A multi-element infrared detector for thermal imaging, wherein the detector includes a main substrate, an aperture plate and a plurality of detector elements formed on the main substrate and arranged thereon in an array. Each detector element having a photosensitive zone and output and common terminal electrodes formed at opposite ends thereof. The aperture plate having at least one aperture for restricting the field of view of the photosensitive zone. The detector includes an auxiliary electrode formed on the rear surface of the aperture plate in a position to contact the common terminal electrodes when the device is assembled. The infrared detector also includes a common metal line formed on the substrate in a position to interconnect a plurality of common terminal electrodes and the auxiliary electrode contacts the common metal line.

Abstract: A centrifugal counter-flow liquid container contactor in which a light liquid and a heavy liquid are introduced into a rotary body fixed to a rotary shaft from the outer peripheral portion and the inner peripheral portion of the rotary body, respectively, so that the light liquid and heavy liquid make counter-flow contact with each other and, after the contact, the light liquid and heavy liquid are discharged from the inner peripheral portion and outer peripheral portion of the rotary body. Disc-shaped partition plates are disposed at both sides of radially extending pipes within the rotary body such as a light liquid introduction pipe, heavy liquid discharging pipe and so forth inserted into the rotary body, so as to separate these radial pipes from the region where the light and heavy liquids are mixed with each other.

Abstract: The present invention provides a method for the desalting of fuel oil by mixing the fuel oil and clean water, thereby separating and eliminating sodium salts and potassium salts contained in the fuel oil, and the method comprises separating a heavy portion including salt-containing water from the fuel oil which is a light portion, this heavy portion separated from the fuel oil being separated into water and a residue by an evaporator, the water being reused as a washing water and the residue being burnt to use the generated heat as a heat source for the evaporator, whereby the residue is decreased in volume and solidified to be made easy in the handling.
