Abstract
This walking motion assisting apparatus includes: an actuator unit which controls operation of a driving body so as to impart to the lower leg an assistive force calculated by applying, to output pattern stored data, a walking motion timing based on a thigh phase angle to be detected; and a terminal device which can wirelessly communicate with a control device of the actuator unit. The terminal device can receive input of an assistive force setting, which includes the duration that the assistive force is applied in a walking cycle, and produces, on the basis of the assistive force setting, output pattern setting data which indicates the relationship between the walking motion timing and the magnitude of the assistive force to be imparted to the lower leg. The control device saves in an overwriting fashion, as the output pattern stored data, the output pattern setting data received from the terminal device in response to human-performed transmission operation on the terminal device.

H01R 31/08 - Short-circuiting members for bridging contacts in a counterpart
[Problem] To provide a terminal attachment structure that can be rigidly and tightly affixed to a terminal attachment plate in a stable state even when vibration and shock are applied to the terminal from the outside and can be assembled with the connecting surface flat without giving rise to a difference in levels between the terminal and the terminal attachment plate. [Solution] The structure comprises a terminal attachment plate (13) having a polygonal shaped bezel part (21) formed by an attachment surface, which is provided so as to be recessed, and a through hole (15), which is provided at the center of this bezel part (21), and a terminal (14) having a flange (18) with the same polygonal shape as the bezel part (21), a leg part (19) extending from the lower surface of this flange (18) and inserted into the through hole (15), and a terminal main body (17) extending from the upper surface of the flange (18). After the flange (18) is inserted into the bezel part (21) so as to join therewith, the terminal (14) is swaged and tightened to the terminal plate (13) by pressing and flattening the leg part (19).
Disclosed is a vehicle starter ring gear in which a drop in the hardness of an outer peripheral tooth, which occurs during the welding to a drive plate can be suppressed. Specifically disclosed is a vehicle starter ring gear which functions as a thermal resistance section for suppressing the heat during the welding to a drive plate (26) from being transferred to outer peripheral teeth (44a) on the outer peripheral side of a plurality of weld zones, namely, weld beads (92) with the drive plate (26) between the inner peripheral surface of a starter ring gear (44) and the gear surfaces of the outer peripheral teeth (44a), and which is provided with a plurality of peripheral grooves (94) formed in the peripheral direction on another side surface (90) in such a manner that the peripheral lengths are longer than those of the weld beads (92), whereby the outer peripheral teeth (44a) of the starter ring gear (44), the hardness of which is enhanced by induction hardening are suppressed from being annealed during the welding between the starter ring gear (44) and the drive plate (26), thus making it possible to suppress a drop in the hardness of outer peripheral teeth (44a) in the vicinity of the weld zones by the welding to the drive plate (26).
An edgewise coil (10) of a rectangular shape in plan view formed by laminating a deformed conductor (10') having a cross sectional shape formed by a pair of long sides (11, 12) and a pair of first and second short sides (13, 14) in multiple layers while bending through the first short side (13). In the vertical cross section before bending, the pair of long sides (11, 12) comprise a pair of straightline areas (11a, 12a) extending approximately parallel with each other from both end parts of the second short side (14) and a pair of tapered areas (11b, 12b) extending between the pair of straightline areas (11a, 12a) and the first short side (13). The pair of tapered areas (11b, 12b) are gradually close to each other toward the first short side (13) in the vertical cross section before bending.
A seal with an IC tag and a method of attaching the seal with the IC tag on a covered container for determining whether a product in the covered container is a genuine article or a fake. The seal (400) with the IC tag is attached to the covered container (600) in a boundary portion between a cover (610) and a container body (620). The seal comprises a base material (41) forming a support body, an antenna (10) with a slit part (14) formed on one face of the base material (41), an IC chip (11) connected to the antenna (10) and fitted to the antenna (10), and an adhesive agent layer (42) formed on the face of the base material (41) on which the antenna (10) and the IC chip (11) are attached. The method of attaching the seal comprises the step of attaching the antenna (10) on the base material through the adhesive agent layer (42) of the seal with the IC tag so as to ride on both the cover (610) and the container body (620).
