Abstract: In the brake apparatus having a rotary pump, outer and inner rotors of the rotary pump are made of bearing steel and inner and outer teeth portions of the rotors are respectively processed by nitriding hardening or carbo-nitriding hardening. Accordingly, outer circumferential region of the outer teeth portion and inner circumferential region of the inner teeth are constituted by nitrided layer containing 15 to 40 percents retained austenite so that teeth faces of the outer and inner teeth portions in mesh may have higher wear resistance.

Abstract: A vehicular headlamp which includes a vessel-like lamp body, a front lens coupled to a front opening of the lamp body to define a lamp chamber, a discharge bulb serving as a light source and a reflector for reflecting light beam emitting from the discharge bulb, wherein the lamp body is provided at a back wall thereof an opening part for exchanging the bulb, a starter unit installing therein a starter circuit constituting a part of a discharge bulb lighting device is secured to the opening part of the lamp body, and a stabilizer constituting a part of the discharge bulb lighting device is secured to a bottom part of the lamp body outside the lamp chamber.

Abstract: A vehicular headlamp including a lamp body, a reflector accommodated in the lamp body and tiltably supported with respect to the lamp body by an aiming mechanism, and an aiming screw which constitutes a part of the aiming mechanism and extends in a front-rear direction of the lamp body. The rear end part of the aiming screw penetrates the rear wall of the lamp body and protrudes rearward from the lamp body. An orthogonal conversion gear mechanism engaging a rear end part of the aiming screw and has a rotational operating shaft linked with the aiming screw for causing the same to rotate. The rotational operating shaft is provided on an upper end thereof with a concave engaging part engageable with the tip of a driver tool. An expanding member protruding from the rear wall of the lamp body covers the orthogonal conversion gear mechanism like a visor. The expanding member also serves as a driver guide for guiding the tip end of the driver to a concave engaging part of the rotational operating shaft.

Abstract: A strain sensor for detecting strain in automobiles, robots, and the like includes a magnetostrictive layer. The magnetostrictive layer is formed by irradiating an alloy layer with a high energy density beam (such as a laser) to form a magnetostrictive layer having an amorphous structure. The resulting magnetostrictive layer has a magnetic inductance in the direction of irradiation that is much higher than in a perpendicular direction thereof. Using such a sensor, it is possible to selectively detect components of stresses and strains in a given direction.

Abstract: A draft device is provided with a rotatable porous roller and a suction tube for establishing a negative pressure within the porous roller. A pneumatic spinning apparatus is provided with a spindle and a nozzle for exerting a whirling air current on a fiber bundle from the draft device. A waste transport pipe is provided for circulating waste discharged from the spinning apparatus back to the porous roller. Waste discharged from the spinning apparatus is thereby recycled to join with the fiber bundle from the draft device.

Abstract: A cleaning device for cleaning a nozzle in a spinning apparatus in which the nozzle unit is supported movably and a suction pipe for sucking yarn waste is oscillatingly supported so that a suction opening of the suction pipe can be moved to a gap between the draft part and the nozzle unit moved away from the draft part.

Abstract: A draft mechanism for use on a spinning machine includes a series of roller pairs each including a bottom roller and a top roller. The roller pairs are connected to output shafts of motors through the use of timing belts. The motors are electrically controlled according to the draft ratios. Roller gauge adjusting shafts are meshed with bearing portions of the top and bottom rollers.

Abstract: An operation starting method for a spinning machine of the type wherein a draft device, an air jetting nozzle and a false twisting device of the nip belt type are disposed in this order, constituted such that, in a condition of the false twisting device wherein belts are held in contact with each other at a nip point, when operation of the spinning machine is started, an air flow directed toward the false twisting device is produced on the air jetting nozzle side of the false twisting device while another air flow directed away from the false twisting device is produced on the opposite side of the false twisting device to the air jetting nozzle.

Abstract: A belt type false twisting device for a pneumatic spinning apparatus in which a fiber bundle is nipped between a pair of endless belts running in an intersecting relationship in mutually different directions to impart false twists to the fiber bundle. A pulley around which each of the endless belts extends is supported for rocking motion around a support shaft.

Abstract: A spinning apparatus comprising a drafting device, an air jet nozzle and a false twisting unit including a pair of endless belts lying in surface contact with each other at a yarn nip point, the drafting device, air jet nozzle, and false twisting unit being located in a path of yarn travel in the order named, the air jet nozzle and the false twisting unit being both movable away from the path of yarn travel, the air jet nozzle and the false twisting unit being movable to and away from each other.

Abstract: A self-illuminated ornamental grill to be mounted between the pair of headlamps of a passenger car, comprising an elongate grill body and an elongate lens which are joined to each other to define a watertight lighting chamber. A pair of fog lamp assemblies or equivalent light sources are mounted in the lighting chamber so as to illuminate the complete length of the lens.

Abstract: A vehicle lamp secured to a vehicle body by slidably inserting the lamp into a bracket from the front of the vehicle body. A rim is formed along the periphery of a lens closing the front opening of the body of the lamp, with the rim being substantially integral with the lens. Two mounting lens extend from the right and left sides of the rim rearward of the lens. The mounting lens are moved towards or away from a bracket secured to the vehicle body at the front of the vehicle body so as to be engaged with or disengaged from the bracket through an engaging structure.

Abstract: Disclosed herein is a headlight of double beam type, which comprises a lamp body having one end closed and the other end open; means defining in a given part of the closed end of the lamp body an aperture; a lens covering the open end of the lamp body; an upper beam projecting unit including a first concave light reflective integrally formed on a part of an inner surface of the closed end of the lamp body, and a first light source installed at a center portion of the first concave light reflector; and a lower beam projecting unit including a condensing lens installed in the lamp body at a position facing the aperture, a second concave light reflector detachably connected to the outside of the lamp body in a manner to face the aperture, and a second light source installed at a center portion of the second concave light reflector.

Abstract: The belt type false twister, in which a pair of pulleys with two travelling endless belts entrained thereabout are mounted fixedly, and in a position off the fiber nipping point of one endless belt there is disposed a roller for urging the said one endless belt toward the other endless belt, a linear travelling portion of the one endless belt being bent and allowed to come close to the other endless belt by the said roller to nip fibers between the closely adjacent belt portions.
