An optical busoptically connects each board of a signal processing sectionand each board of a transmission/reception sectionfor transmitting an optical signal output to the optical busby each board of the signal processing sectionto each board of the transmission/reception sectionin a non-block state. In contrast, the optical bustransmits an optical signal output to the optical busby each board of the transmission/reception sectionto each board of the signal processing sectionin a non-block state.

Radio communication apparatus

In an optical wiring board, an optical components including a planar optical waveguide, a plurality of first optical fibers optically connected via a transmissive diffusion plate to a light incident face of the waveguide, and a plurality of second optical fibers optically connected to a light emitting face of the waveguide is placed on a support board. The optical component is sealed by a sealing member made of a resin.

Optical wiring board, optical bus system, and method of manufacturing optical wiring board

Master node #and a plurality of slave nodes #to #are connected to one another via a plurality of optical couplers. Each of the nodes is controlled so that signal transmission between the nodes by a bus connection and a link connection is conducted via the optical couplers. In the link connection, the master node transmits bit signals corresponding to the number of the slave nodes. Each of the slave nodes transmits a bit signal with allocating the signal to a predetermined bit.

Optical transmission apparatus

A first optical wave guideand a second optical wave guideare connected to both sides of a planer optical waveguiderespectively. The other endsof the first and second optical wave guidesare extended over an upper surfaceof an optical wiring circuit board. An electric wiring circuitis connected to the other endsof the first and second optical wave guides, thereby constituting an optical wiring circuit. A plurality of optical wiring circuitsare superimposed on one another to thereby form an optical wiring circuits layered body. The electric wiring circuitcan be connected from one surface of the optical wiring circuit board, which makes it possible to facilitate the connection thereof.

Optical wiring circuit, optical wiring circuits layered body and opto-electric wiring apparatus

A display device having a memory property capable of maintaining a displayed information even in a state of being separated away from a power source as a result of decreasing the effect of external noise. The display device is detachably attached to a control unit that includes a drive circuit and a power source for driving the display device. The display device has a memory property and maintains the displayed image even in a state of being detached from the control unit. An input protection portion which is an electric load such as resistor, IC or capacitor is provided for the input portion leading to matrix electrodes from the connection terminals for electrically connecting the display device to the control unit. This prevents the infiltration of noise through the connection terminals and lowers a change in the displayed image.
