    摘要: A video distribution system is provided that is capable of distributing the same advertisement both to an originating user terminal and to a destination user terminal. Upon receipt of http request, WWW server transmits a call processing and video distribution request to a coordination server. At this time, the telephone numbers of the originating user terminal and the destination user terminal, and video to be distributed are specified by the call processing and video distribution request. Upon receipt of the call processing and video distribution request, coordination server performs originating call control and sets up a video distribution using a call processing protocol such as SIP. This results in setting up a telephone conversation between the originating user terminal and the destination user terminal, and setting video distribution to and receipt by destination user terminal. Coordination server then transmits an originating-side video distribution request to the video distribution server. Upon receipt of the originating-side video distribution request, the video distribution server performs video distribution to the originating user terminal.

    摘要: An electromagnetic wave absorber comprises an electromagnetic wave absorber molded element, plate-shaped sintered ferrite, and a metal plate. The molded element incorporates a tile-shaped base portion and a wedge-shaped apex portion disposed on the base portion. The molded element is formed by injecting slurry into a mold, the slurry being obtained through mixing a molding material for the wave absorber with water, and curing the slurry. The molding material includes a magnetic material, an inorganic fiber and an inorganic binder. When these ingredients are mixed with water, the molding material first exhibits fluidity and then a curing reaction in a temperature range of 1 to 40° C.

    摘要: A liquid crystal device for driving a liquid crystal by an electric field generally in parallel with a substrate plane. In this liquid crystal device, voltage waveforms having phases different by a half period are separately applied to even row common electrode lines 5 and odd row common electrode lines 6, so that the charging/discharging of the inline parasitic capacitance in the liquid crystal device, created at a polarity inversion time, are reduced to decrease the power consumption. In order to reduce the bluntness of a common electrode driving signal at a thin film transistor liquid crystal display panel, moreover, a common electrode driving unit includes differential signal superposing means for generating a differential signal and superposing it upon the common electrode driving signal.

    摘要: A high frequency amplifier containing: a constant envelope signal generation circuit for transforming an input signal to form two constant envelope signals where phases of the constant envelope signals correspond to an amplitude of an envelope of the input signal; two amplifying circuits for separately amplifying two constant envelope signals; and a power synthesizing circuit for synthesizing the first and second amplified signals to generate an amplified signal of the input electric signal, and reflecting remaining components of the first and second amplified signals which remaining components remain in the above synthesizing operation, toward the first and second amplifying circuits. Further, an input impedance of the power synthesizing circuit may be controlled by shifting phases of the above reflected components by respectively predetermined amounts, or by adaptively shifting phases of the above reflected components responding to an input level, so that a total efficiency of the high frequency amplifier is maximized. The high frequency amplifier may contain, instead of the above two amplifying circuits and the power synthesizing circuit, a circuit for inverting a phase of one of the two constant envelope signals; and a single-ended push-pull amplifier circuit for receiving the other of the two constant envelope signals, and an output of the phase inversion circuit, and synthesizing the received signals to generate an amplified signal of the input electric signal.
