摘要:
In a drive force transmission apparatus, when an input shaft is rotated in a normal rotational direction, a rotational force of the input shaft is transmitted to an output shaft through a one-way clutch to rotate the output shaft at a rotational speed, which is the same as a rotational speed of the input shaft. At this time, an input side sub-shaft is freed from an output side sub-shaft. In contrast, when the input shaft is rotated in a reverse rotational direction, the rotational force of the input shaft is transmitted to the output shaft through an input gear, a first gear, the input side sub-shaft, a two-way clutch, the output side sub-shaft, a second gear and an output gear. At this time, the output shaft is freed from an intermediate shaft.

A feed screw mechanism including a screwed shaft which moves linearly along with the control shaft, and a rotation spindle which rotates in a circumferential direction. The feed screw mechanism converts a rotational movement of the rotation spindle into a linear movement of the screwed shaft. A protrusion protrudes outwardly from the rotation spindle. An internal thread member engages with an outer wall surface of the rotation spindle. A motor stator generating a magnetic is positioned over the rotation spindle, and is sandwiched between the protrusion and the internal thread member in an axial direction of the rotation spindle.

A first core is formed by stacking a plurality of magnetic plates of a soft magnetic material, such as iron, in a direction perpendicular to a plane of each magnetic plate. A bonding thin layer made of iron oxide having a thickness of approximately a few nanometers to a few hundred micrometers is formed between adjacent ones of the magnetic plates. The adjacent magnetic plates are bonded to each other by diffusion bonding in such a manner that the bonding thin layer is interposed between the adjacent magnetic plates to electrically insulate between the adjacent magnetic plate.

The invention provides a method for preparing a soft magnetic material which meets demands for low iron loss, high density, high strength and high productivity. The method comprises a surface oxidation step of forming oxide films on the surfaces of a soft magnetic powder, a step of preparing a molding compound of the soft magnetic powder by mixing a soft magnetic powder and a binder with a predetermined blending ratio, a press molding step of press-molding the molding compound of the soft magnetic powder into a predetermined shape, and a sintering step of sintering the press-molded soft magnetic powder to produce a soft magnetic material, wherein a millimeter wave sintering apparatus or a discharge plasma sintering apparatus is used as a heating means in the surface oxidation step or in the sintering step. Thereby, energy of millimeter waves or discharge plasma acts locally on oxidized surface portions having a large electric resistance of the soft magnetic powder, the surfaces of the soft magnetic powder are locally heated at a temperature near the melting point, and oxidation of the surfaces of the soft magnetic powder (formation of an oxide film) and sintering (diffusional joining between oxide films) are promoted.

An actuator for a valve lift control device linearly moves a control shaft to change a valve lift in accordance with an axial position of the control shaft. A first and a second rotation cam integrally rotate around a common rotation axis by transmission of torque, so that a direct acting follower, which includes a first and a contact members, linearly moves with a control shaft. The first and a second rotation cams are respectively in contact with the first and the second contact members via a first and a second contact points. The first contact point is located on the opposite side of the second contact point with respect to the rotation axis. A sum of a first rotation cam lift of the first rotation cam and a second rotation cam lift of the second rotation cam is substantially constant in a predetermined rotation angular range of the first rotation cam and the second rotation cam.

摘要:
An optical connector assembly (1) for connecting an optical fiber (9), an optical element (4) (light-emitting element or light-receiving element), and an electric circuit together. A bolt (32) of an optical fiber-mounting fitting in which the optical fiber (9) is inserted in the hole of an elastic seal and a bolt (31), is screwed into a threaded hole formed in a housing (2) of the plug (1) that accommodates the optical element (4) in order to couple the optical fiber (9) to the plug (1). The connection between the optical element (4) and the electric circuit is accomplished by a jack (20) and the plug (1) is provided with a lock mechanism based on a push-type lever (20), featuring improved sealing performance against water, oil, dust and dirt.
