A method for producing a master disk 105 for an optical disk 110 includes a layer forming step of forming a heat-sensitive material layer 102 on a substrate 101, an exposure step of exposing the heat-sensitive material layer 102 partially to a laser beam, and a pit and land pattern forming step of forming a pattern of pits and lands by means of the difference between the etching rates of the exposed portion and the unexposed portion of the heat-sensitive material layer 102. The heat-sensitive material layer 102 includes at least Sb and O. When the composition ratio of O is defined as x (atom %), x is 3 or more and 50 or less.

The subject of the invention is a ball joint for motor vehicles with a bearing shell arranged between a joint housing and a ball head. The shell is provided at one end with elastically deformable ribs projecting from a stop surface. So that the ribs, after compensating for production tolerances, can absorb, in the elastically deformable zone, additional axial shock loads occurring in driving operation, it is proposed that the ribs be designed as square ribs, running radially, and separated by grooves from the stop surface adjoining their side walls, while the volume of each rib projecting above the stop surface, before mounting, is approximately equal to the free volume of the two grooves adjacent to it, so that the side walls of the grooves lying next to the stop surface act in the mounted condition as support walls for the elastically deformed ribs.

A wearable jacket includes a 2D-DST substrate shaped to cover a body of a subject person. The 2D-DST substrate includes a first conductive sheet, a second conductive sheet and a plurality of communication modules. The first and second conductive sheets are overlapped, and the first conductive sheet is located on the subject person side when in use. The plurality of communication modules are distributed between the first and second conductive sheets. At least one of the plurality of communication modules has a communicating system capable of communicating with an external device by receiving and/or transmitting a spatially propagating signal. One of the first and second conductive sheets on the external device side is formed with an area that allows the spatially propagating signal to pass through at a position corresponding to a location of a communication module having the communicating system.

An optical communication device includes a light source that emits a light beam and an optical fiber having a core and a cladding. The optical fiber has a light entrance face having a core region and a cladding region. The light beam emitted by the light source is converged by a converging lens on the core region and is transmitted through the optical fiber. The entrance face is configured to generate a light intensity distribution in light reflected by the light entrance face depending on a position where the light beam is incident on the entrance face, a converging lens arranged between the light source and the optical fiber.

An image signal processing device for processing an image signal transmitted from an imaging unit by radio is provided. The image signal processing device is provided with at least one antenna that receives the image signal transmitted from the imaging unit by radio, a substrate, and a plurality of 2D-DST elements arranged on the substrate. The plurality of 2D-DST elements include a plurality of receiving elements each of which includes a processing unit having functions of receiving the image signal and processing the received image signal. The plurality of receiving elements are connected to the at least one antenna. At least a part of the plurality of receiving elements contributes to time-division multiplexing of receiving the image signal and processing the image signal.
