A toothbrush having a handle, a head with oral care elements and a neck connecting the head with the handle is described. The toothbrush has a base structure of the handle, and the neck and the head are formed by a hard plastic component. Said basic structure of the handle is covered, at least in part, by a first soft plastic component. Said head including a second soft plastic component and said neck including a through-opening, wherein at least one section of a boundary wall of the opening is provided with an elastic muscle.

The invention relates to a bistable electromagnetic actuating apparatus (1) having an actuating element (2), which forms an engagement region (4) at the end and can be moved axially between two end positions, in particular for engaging in a control groove in a cam of an internal combustion engine, and having a coil device (11) which is provided in a stationary manner relative to the actuating element (2) and is designed to exert a force on said actuating element, wherein the actuating element (2) has permanent-magnet means (5) which are designed to interact with a core region (3) which is provided in a stationary manner relative to the actuating element (2), and wherein the coil device (11) is designed to generate a counterforce, which counteracts a retaining force of the permanent-magnet means (5) and releases said permanent-magnet means from the core region (3), in response to an electronic actuation signal, and wherein spring means (14) are provided, said spring means being arranged such that they apply a spring force to the actuating element (2) in an axial direction which faces away from the core region (3). The invention makes provision for the core region (3) and the permanent-magnet means (5) to overlap in the axial direction for the purpose of influencing the retrieval point.

The invention relates to an arrangement for screw locking electric connecting terminals, comprising a body or a housing-like element (1) made of insulating, deformable material, preferably a plastic material, in which a perpendicularly extending duct (2) is integrally formed, into which a screw (3) including the head (4) thereof can be screwed in a sunken way. A profile (6) is provided in the region of the duct wall (5) for securing the sunken screw (3), said profile being elastically deformable when screwing in the screw (3) and while passing over the head (4), wherein the profile (6) is deformed back toward the inside of the duct for securing the screw (3) after passing over the head (4). According to the invention, the duct wall (5) is provided with a groove (8) integrally formed in the material, wherein the screw (3) or the duct (2) has a noncircular shape.

The invention discloses a shoulder (1) for retaining a railway rail fastening clip (3), which comprises two interconnected spaced-apart walls (10), between which a portion of the clip (3) to be retained is held in use, and clip-engaging means (11), supported by the walls, for engaging a portion of the clip (3) to be retained, does not have any feature or surface which engages the surface of that clip portion which faces downwardly when the clip is in use. As selected, when the shoulder (1) is located at an effective work direction, the shoulder (1) is used abutting with the rails, at this point, any portion of the contact regions 11OA and 11OB of the shoulder (1) can be seen from upwards to downwards. As selected, when the shoulder (1) is in use, the contact regions 11OA and 11OB of the shoulder (1) both has a same apart horizontal distance from the edge of the foot, wherein, the horizontal distance is measured by a railway rail axis perpendicular to the foot plane.

The invention discloses a mounting structure of an electric box. The mounting structure comprises a mounting buckle and a mounting hole on the electric box, wherein the mounting buckle adopts a thin buckle shape with a preset thickness and has a structure by which the mounting buckle can be fixed on the wall surface; the mounting hole is arranged on the bottom surface of the electric box, and a depth matched with the thickness of the mounting buckle and a cross section matched with that of the mounting buckle in shape and size; and a buckling structure is formed between the mounting buckle andthe mounting hole, and the electric box can be directly inserted in the mounting buckle through the mounting hole for fixing. Compared with the prior art, the mounting structure of the electric box can conveniently insert the electric box in the mounting buckle to fix the electric box only by fixing the mounting buckle of which an area is far smaller than that of the mounting bottom plate in theprior art. Because the mounting buckle and the electric box can be directly inserted and matched, the electric box can be detached without detaching the buckle first, and the mounting and demounting actions are simplified.

The invention relates to an implement method for high speed single bus communication. Data double-way transmission is performed on basis of an SDI signal line, the SDI signal line is connected with a host and a slave, the host sends signals through the SDI signal line, the slave is automatically adapted to receiving rate and starting and stopping of communication according to the received signals so that a self adaption one wire (SAOW) host-slave structure is formed, data information is transmitted by means of a command frame structure in terms of the data double-way transmission, and a command frame comprises a frame header, a slave address, a register address, data length, data and a frame tail. By means of the implement method for high speed single bus communication, one-bus double-way communication can be achieved, two communication parties are not required to use fixed baud rate, the baud rate can be changed whenever possible, and the method can be applied to occasions with unstable working frequency.
