In a power source control circuit module, switching regulator devices and a linear regulator device are mounted on a surface of a laminated body so as to be spaced from each other. In an interface between dielectric layers of the laminated body, first to fifth internal ground electrodes separated by an electrode non-formation portion are provided. The first, second, fourth, and fifth internal ground electrode are connected to the respective switching regulator devices. The third internal ground electrode is connected to the linear regulator device. The first to fifth internal ground electrodes are connected to respective different external ground terminals.

The video signal processor 10 includes a scene detector 16 which uses features extracted for visual segments and/or audio segments resulted from segmentation of an input stream of video data, and a criterion for measurement of similarity between visual and/or audio segment pairs, calculated for each of the features using the similarity measurement criterion, to detect two visual segments and/or audio segments whose time gap is within a predetermined temporal threshold and whose dissimilarity is less than a predetermined dissimilarity threshold and group the segments into a scene consisting of visual segments and/or audio segments reflecting the semantics of the video data content and temporally contiguous to each other.

A highly reliable semiconductor device having an underlying film with a trench and a conducting material film formed in the trench, a method of manufacturing the same and a method of forming a resist pattern used therein are obtained. The underlying film having an upper surface and the trench is formed. The conducting material film is formed on the upper surface and in the trench. A photo resist film is formed on the conducting material film located on the upper surface of the underlying film and in the trench. The photo resist film is left in the trench whereas the photo resist film is developed and removed outside the trench. The conducting material film located on the upper surface of the underlying film is etched and removed with the photo resist film left in the trench used as a mask.

A direction coupler makes it possible to freely select an input terminal and an output terminal thereof. A branch unit (6) containing a branching circuit (6a) is mounted so that the branch unit (6) can be rotated relative to a mother board (5), with a central portion of the branch unit (6) being a fulcrum. Relay terminals (11, 12, 13, 14) of the mother board (5) are provided at positions corresponding to an input terminal (15) and an output terminal (16) of the branch unit (6).

A high-frequency signal branching device comprises a main body having an input terminal and an output terminal for connecting trunk cables on an input and an output side, respectively, and a branch body having a branch terminal for connecting a branch cable. This construction allows the number of branch terminals to be increased by replacing the branch body while keeping the main body intact. A branching circuit for branching a high-frequency signal from the trunk cable is provided in the branch body. Accordingly, the branching circuit also can be replaced by replacing the branch body.

A highly reliable assembly structure is provided by surely reducing a stress to be exerted on leads of a TCP device. Part of a soldered portion of outer leads that is located closer to a semiconductor chip of the TCP device is reinforced by a support ring formed on a side of the outer leads opposite from a circuit board, so that a stress to be exerted on the outer leads is dispersed to the leads, the support ring and solder to thereby prevent the possible occurrence of metal fatigue of the leads.
