A plurality of engaging pieces each formed of washer (35) for instance are fixed to the rear surface of a building board (30). A plurality of elongated fixtures (10), each provided at the lower end thereof with an engaging tongue (20a) and at the upper end thereof with an engaging region (12a) designed to be engaged with the engaging tongue (20a), are engaged with the engaging pieces. The fixtures (10) thus engaged are directly fixed to the posts (1) or studs (2) of a building. Since each fixtur...

A flip-flop circuit with embedded scan capabilities uses a skewed latch to pull one end of the flip-flop either up or down while another end of the flip-flop is active. Further, the flip-flop is designed such that a data node and a scan node are coupled to a master stage, which contains the skewed latch. The data node and scan node values are initially generated from different ends of the flip-flop. Based upon clock dependencies and whether the flip-flop is in a normal mode or a scan mode, the m...

In a digital satellite television system in which a television receives its signal via receiver/decoder, such as a set top box, interactive applications can be downloaded and run on the receiver/decoder. The application code is arranged as modules, and the downloading of modules is preceded by searching a directory module within a specified local address. The modules are signed and the directory module is signed and encrypted so that a single encryption applies to all of the modules making up th...

A cluster of multiprocessing nodes uses snooping-based cache-coherence to maintain consistency among the cache memories of the multiprocessing nodes. One or more of the multiprocessing nodes each maintain a directory table that includes a list of addresses of data last transferred by cache-to-cache transfer transactions. Thus, upon a local cache miss for requested data, a multiprocessing node searches its directory table for an address of the requested data, and if the address is found in the di...

A wideband signal analyzing apparatus for analyzing an input signal includes frequency-shifting means for generating a plurality of intermediate frequency signals by shifting a frequency of the input signal as much as respectively different frequency-shifting amounts, so that if a frequency band of the input signal is divided into a plurality of frequency bands, each of the frequency bands can be shifted to a predetermined intermediate band, spectrum measuring means for outputting a complex spec...

A digitizer module comprises an AD converter for sampling a pair of analog signals at a predetermined time interval and converting into a first and second digital signals respectively, a second signal frequency component calculating unit for calculating a second signal frequency component representing a component of each frequency of the second digital signal on the basis of the second digital signal, a skew frequency component calculating unit for calculating a skew frequency component represen...

At both ends of a waveguide 43 having a plurality of cores 51, light emitting elements 47 and light receiving elements 49 are disposed so as to face end faces of the cores 51. A switch 44 is overlapped over the waveguide 43. In the switch 44, switching windows 52 each can be switched between a state where light propagating through the core 51 is passed and a state where the light is reflected are arranged in the vertical and horizontal directions, and the switching windows 52 are arranged along ...

Since a cursor displayed on a screen of a television monitor moves in conjunction with a motion of an operation article operated by a player, intuitive operation can be possible so that the player can play a game easily. A mermaid displayed on the screen follows the cursor when the player moves the cursor by operating the operation article. In this way, the player operates the mermaid indirectly and avoids obstacle objects and obstacle images.

There is provided a delay circuit that delays an input signal to output the delayed signal. The delay circuit includes a first delay element operable to receive the input signal and delay the input signal to output the delayed signal, a buffer operable to receive the delay signal output from the first delay element and correct a dullness of a waveform of the delay signal generated from the first delay element to output the corrected signal, and a second delay element operable to receive the dela...

Techniques have been developed whereby information objects referenced in a requested information object (e.g., image, audio, video, application, and/or text objects referenced in an HTML document) are embedded in a composite object and supplied in as literal data therein in response to an object identifier (e.g., an URL request). Referenced information objects may be retrieved from cache or obtained from authoritative information servers and dynamically embedded in a composite information object...
