Abstract: A method for producing a plated part, includes: applying a catalyst inactivator to a surface of a base member; irradiating with light or heating a part of the surface of the base member to which the catalyst inactivator is applied; applying an electroless plating catalyst to the surface of the base member; and bringing an electroless plating solution into contact with the surface of the base member applied with the electroless plating catalyst to form an electroless plating film at a light-irradiated portion or a heated portion of the surface.

Abstract: A failure is detected immediately and certainly, and continuation of processing in an unstable state is prevented. A first error detection code is generated from first information which is output as a result of execution of a predetermined program conducted by a first processor. A second error detection code is generated from second information which is output as a result of execution of the program conducted by a second processor which is configured so as to output the same computation result as that of the first processor. It is detected whether the first information is the same as the second information, and it is detected whether the first error detection code is the same as the second error detection code. Writing the first information or the second information into a main memory is controlled on the basis of a result of the detection.

Abstract: Disclosed is an optical information recording medium having a printable region on a label surface which is extended to a clamping area, and label information such as a name of a manufacturer is printed in the clamping area. The optical information recording medium includes a substrate having label information pits serving as non-recording and non-reproducing pits that are formed in the clamping area and a reflective layer laminated on the label information pits, and a dummy substrate to be attached to the substrate through an adhesive layer formed on the reflective layer. The multiple label information pits are formed substantially in an entire region of the clamping area to display the label information which emerges by linking portions where the label information pits are not formed.

Abstract: An optical information-recording medium has a plurality of lands and grooves formed on a substrate. In-groove pits are formed at the bottom of a part of the grooves. The widths of the in-groove pits in the radial direction of the substrate are suppressed from being widened irrelevant to the lengths in the groove direction. Predetermined shapes of the land and the groove are maintained for the shape of the land disposed adjacently to the in-groove pit without greatly eroding or scraping the side wall. A recording signal obtained from land prepits can be reliably detected on the optical information-recording medium manufactured by using the substrate formed with the land prepits disposed adjacently to the in-groove pits.

Abstract: In a broadcasting satellite, signals transmitted through an up transmission line of a Ka band, which includes a plurality of communication channels, are received by a Ka-band antenna. The signals received by the antenna are passed through band-pass filters to thereby extract a broadcasting signal transmitted through each communication channel. Those of the thus-extracted broadcasting signals, which have been transmitted through predetermined communication channels, are synthesized by each of synthesizers, then amplified by a corresponding one of high power amplifiers, and output to a corresponding one of a plurality of primary radiators employed in an S-band antenna. The S-band antenna transmits each synthesized signal to a predetermined area that corresponds to a corresponding primary radiator. Thus, the system can be made to a simple structure, and the service area can be changed for each broadcasting signal.
