In an embodiment, an integrated circuit (IC) device is disclosed. In the embodiment, the IC device includes a load modulation module, a current source coupled to the load modulation module, an interface to a resonant circuit, the interface coupled to the load modulation module and the current source, and an interface to a charge source, the interface coupled to the current source, wherein the load modulation module is configured to provide a signal for transmission by modifying the load through the load modulation module, and wherein the current source is configured to provide a signal for transmission by generating pulses of current.

An object of the present invention is to provide an engine starting device which can prevent rattling of an ignition switch in a coupled state. Provided is an engine starting device including: a housing 2 accommodating a rotational operation shaft 1; and an ignition switch 3 coupled to the housing 2 and configured to be actuated upon application of rotational operation force to the rotational operation shaft 1. The ignition switch 3 is fitted and held in an attachment recess 4 formed in the housing 2, in such a way as to be prevented from falling from the attachment recess 4 by appropriate snap-locking portion 5. The peripheral wall surfaces of the ignition switch 3 and the attachment recess 4 on the fitting start end side and the peripheral wall surfaces thereof on the fitting finish end side come into pressure contact with each other substantially simultaneously with each other when the depth of the fitting of the ignition switch 3 to the attachment recess 4 reaches a predetermined depth, to thereby reduce rattling in the radial direction.

A locking assembly for a vehicle steering column includes a shaft. Also included is a slip ring having a plurality of apertures defined by a plurality of aperture walls, each of the aperture walls having a corner, the slip ring surrounding at least a portion of the shaft. Further included is a lock sleeve surrounding at least a portion of the slip ring, at least one of the corners of the plurality of aperture walls frictionally engaging one of an outer surface of the shaft and an inner surface of the lock sleeve to establish a fixed interface on a first side of the slip ring, the slip ring having a second side that establishes a slip interface with one of the shaft and the lock sleeve.

A band-based lock is provided. The band-based lock may include a flexible band with a substantially thin profile and include inner metal layers and wires and/or jacketed metal layers so that the band may be more difficult to cut. The band-based lock may include a feed mechanism coupled to the flexible band. The feed mechanism may provide for the flexible band to be fed through the feed mechanism, putting the flexible band in a loop. The feed mechanism may allow the flexible band to be fed through the feed mechanism in one direction when in a tightening or locked position. The feed mechanism may allow this one-way feed through use of a pawl including one or more teeth engaging with teeth formed on the flexible band. In a release position, the feed mechanism may allow the flexible band to be fed backward through the feed mechanism opening the loop.

In a mechanical steering lock for vehicles, an angular locking nib of a steering shaft is movable away from and towards a releasing position, in which the free rotation of the steering shaft is allowed, and is withheld in this releasing position by two retaining means arranged parallel to each other and one of which comprises a stop element movable away from and towards a retaining position, in which it cooperates abutting against an axial shoulder of the nib.

A rotary switch device includes a fixed contact point part and a movable contact point part. The movable contact point part is rotated on the fixed contact point part so as to connect and disconnect the fixed contact point part and the movable contact point part. The fixed contact point part and the movable contact point part have contact surfaces which are band shapes and to which corrosion-resistant conductive processing is applied. A transient contact region, in which a contact point is moved from one end portion to the other end portion in a predetermined connection-operation angle from a contact start point with respect to the other of the fixed contact point part and the movable contact point part, is provided on each of the contact surfaces.

The purpose of the present invention is to provide a steering lock device that can prevent improper access to a cylinder lock due to the deformation of a mounting hole formed in a cut-out shape. The steering lock device comprises: a frame (4) that is provided with a cylindrical section (1) open at one end, and that houses a lock body (3) which moves in and out of a steering column as a result of the manipulation of a cylinder lock (2) secured in the cylindrical section (1); and a mounted member (6) that is mounted in a mounting hole (5), one end of which opens to the open end of the cylindrical section (1) and is formed in a cut-out shape. At both side ends of the mounting hole (5), to-be-locked sections (9) are provided that regulate the widthwise deformation of the mounting hole (5) by locking circumferentially with locking sections (8) of an inserted member (7) which is inserted into the cylindrical section (1) within the frame (4).
