Abstract: A device management system (1) includes a common certification information acquirer, a certifier, an identification information generator, and a setter. The common certification information acquirer acquires common certification information from a device (10) including a storage for storing the common certification information. The common certification information stored in the storage is shared with another device. The certifier certifies the device (10) based on the common certification information. The identification information generator generates identification information for identification of the device (10) certified by the certifier. The setter sets the identification information to the device (10).

Abstract: A powder coating composition for PC strand coating which, when used for the coating of a PC strand, can advantageously form a coating film having an even thickness at low cost without causing uneven thickness or stringness is disclosed. The powder coating composition of this invention for PC strand coating is characterized by having a melt viscosity of 3,000-15,000 poise.

Abstract: A reclining apparatus for adjusting a tilt angle between a first member and a second member includes: a base plate mounted to the first member; a gear plate mounted to the second member and assembled with the base plate rotatably relative to each other; a gear mechanism for controlling engagement of the gear plate with the base plate; and a cover having a first tubular portion fixed to an outer periphery of the base plate and a second tubular portion in slide contact with an outer periphery of the gear plate, the cover being configured to allow the base plate and the gear plate to rotate relative to each other and to suppress a relative movement therebetween in an axial direction. The first tubular portion is coupled by welding to the outer periphery of the base plate.

Abstract: An internally-toothed plate 105 and an externally-toothed plate 106 are fitted together so that a portion of an externally-toothed gear 161 of the externally-toothed plate 106 is located in a recess 151 such that the externally-toothed gear 161 a meshes with an internally-toothed gear 151a, and so that a bearing portion 151b of the internally-toothed plate 105 is located in a recess 161. In other words, the externally-toothed plate 106 is fitted into the internally-toothed plate 105. At this time, a seat cushion bracket 121 to which the internally-toothed plate 105 is fixed by laser welding is in contact with an outer peripheral edge 163 at the back side of the recess 161 of the externally-toothed plate 106. As a result, a reclining device with a reduced number of components and size can be obtained.

Abstract: A reclining apparatus includes: a base plate on the first member; a gear plate on the second member and pivotably combined to the base plate; first and second guide portions on the base plate; first and second guide surfaces on the first guide portion; first and second guide surface on the second guide portion; first and second locking gear that are engageable with the gear plate; and a movable guide interposed between the first guide portion or the second guide portion and the first locking gear or the second locking gear. The first guide surface of the second guide portion faces the first locking gear. A recess is provided in the second guide surface of the first guide portion that orients the same pivotal direction as the first guide surface of the second guide portion to reduce a contact area with the second locking gear.

Abstract: An object of an aspect according to the present invention is to provide a reclining apparatus capable of reducing the cost. A center shaft of the reclining apparatus is inserted through through-holes respectively bored at the center portions of a base plate and a gear plate. The center shaft coaxially and pivotally supports the base plate and the gear plate. An annular protrusion provided at the center shaft is sandwiched between the base plate of the reclining apparatus and a bracket on a seat side. This prevents the center shaft from coming off.

Abstract: The object of the invention is to provide a reclining device which improves engagement between a lock gear and a gear plate for reliable locking without requiring high dimensional accuracy. Four lock gears comprising a pair of first lock gears 40, and a pair of second lock gears 50 in which a gap between the second lock gear 50 and guide protrusions 12, 13 is larger than a gap between the first lock gear 40 and guide protrusions 11, 12 are adopted. Due to elastic function of a biasing member body 90a of an biasing member 90, both the second lock gears 50 are biased radially and inwardly and toward the guide protrusion 13 of the base plate 10.

Abstract: A reclining device capable of eliminating mechanical play in a front-rear direction of a seat back is provided. Particularly, a reclining device reliably capable of locking and releasing is provided at an inexpensive cost. Movable guides are slidably disposed respectively between lock gears and a fixed guide. Each of the movable guides is formed in a shape that the width thereof gradually decreases from the outer end toward the inner end. In the sliding faces of the respective movable guides, a sliding face on the lock gear side is arranged to be parallel to a movement direction of the lock gear and the sliding face at the fixed guide side is inclined with respect to the sliding face at the side of the lock gear. Each of the movable guides engages with a spring and the spring imparts a force to the movable guides in an inner direction of a base plate.

Abstract: A vehicle seat reclining apparatus is provided in which the strength of a connecting portion positioned directly or nearly directly below a receiving wall face of a guide portion of a fixed-side housing is higher than in a conventional reclining apparatus. A protruding guide portion is provided in a fixed-side housing used to configure a reclining apparatus. A receiving wall face that makes contact with a locking gear used to configure the reclining apparatus and which thus guides movement of the locking gear, and a top face that is continuous with that receiving wall face, are formed in the guide portion. A tapered chamfer portion is present at an edge of the receiving wall face where the receiving wall face and the top face of the guide portion intersect. A thick portion with a tapered face that corresponds to the chamfer portion is provided directly or nearly directly below a base end portion of the receiving wall face.
