摘要:
A semiconductor device having a semiconductor substrate or an insulation layer, an integrated circuit on each of the opposite sides, or main surfaces, of the semiconductor substrate or insulation layer, and a path for an ultrasound signal interconnecting the integrated circuits. The path is afforded by an ultrasonic transducer on each of the opposite sides of the semiconductor substrate or insulation layer. A plurality of paths may be provided in the same semiconductor substrate or insulation layer without crosstalk by transmitting ultrasound signals having different frequencies through the respective paths. The paths may be one-way or two-way. The ultrasonic transducers each contain a piezoelectric material; the thickness of the piezoelectric material in the ultrasonic transducer, at least on the receiver side in each path, is such that the resonant frequency of the ultrasonic transducer corresponds to the frequency of the ultrasound signal signal transmitted through the path. A plurality of paths through a semiconductor substrate or insulation layer for transmitting corresponding ultrasound signals of the same frequency may be provided between at least one point on one side and more than one point on the other side in a time sharing manner.

A protective semiconductor integrated circuit device for protecting an internal circuit against an excessively high voltage has a first resistor of a low value resistance interposed between an input terminal and an input gate of the internal circuit. One of the drain and source regions of an MIS type transistor is connected to the input gate of the internal circuit to be protected and the other region of the source and drain is grounded. A capacitor is interposed between the gate of the MIS transistor and the input terminal. A second resistor or a diode of reverse polarity is interposed between the gate of the MIS transistor and ground. The protective device may be fabricated using, a bulk silicon, an insulating substrate such as sapphire, spinel or semi-insulating material, simultaneously with the internal circuit and without changing processes for fabrication of the internal circuit and without requiring any additional masking steps.

The present invention provides a display panel that can improve the adhesion strength of a sealing member and that can reduce moisture permeation caused by an alignment film without performing a treatment to remove the alignment film. A display panel according to the present invention is a display panel having a pair of substrates attached to each other via a sealing member. At least one of the pair of substrates has a configuration in which a transparent resin film and an alignment film are laminated. In the display panel, a side face of an edge of the transparent resin film has a reverse tapered shape; the alignment film is separated at the side face of the edge; and the transparent resin film and the sealing member are attached to each other without having the alignment film therebetween.

[Problems] The object of the present invention is to provide a Medical Drugs which reduce damage of gastrointestinal mucosal induced by NSAIDs.[Means for Solving Problems]The Medical Drugs that comprises a mixture of NSAIDs and sugar that reduce damage of gastrointestinal mucosal induced by NSAIDs is already known. However the mixture is not enough to suppress damage of gastrointestinal mucosal. The inventors invented new molecular compounds with NSAIDs and trehalose. The new molecular compounds effectively reduce damage of gastrointestinal mucosal induced by NSAIDs.

There is provided an information processing apparatus in which a CPU and an audio processing unit are coupled by a bus. The audio processing unit includes a ring buffer that temporarily retains audio data, and performs an input/output process of the audio data. An interrupt signal generator generates a buffer empty signal, when the audio data is output from a buffer in the ring buffer and the buffer is empty, decimates the buffer empty signal in accordance with a sampling frequency of audio, and then feeds the interrupt signal that survives the decimation to the CPU. The CPU, upon receiving the buffer empty signal, issues a DMA transfer instruction for writing the audio data into the empty buffer in the ring buffer.

Laser beams emitted by a plurality of laser sources are divided into a plurality of sub-beams, which are irradiated onto selected portions of an amorphous semiconductor on a substrate to crystallize the amorphous semiconductor. A difference in diverging angles between the laser beams is corrected by a beam expander. The apparatus includes a sub-beam selective irradiating system including a sub-beam dividing assembly and a sub-beam focussing assembly. Also, the apparatus includes laser sources, a focussing optical system, and a combining optical system. A stage for supporting a substrate includes a plurality of first stage members, a second stage member disposed above the first stage members, and a third stage member 38C, rotatably disposed above the second stage to support an amorphous semiconductor.

A secondary texture cache is used commonly by a plurality of texture units, and stores part of texture data in a main memory. A cache controlling CPU controls a refill operation from the main memory to the secondary texture cache in accordance with cache misses of the plurality of texture units, so as to suppress occurrence of thrashing in the secondary texture cache. The cache controlling CPU suppresses occurrence of the refill operation when the plurality of operating units access an identical memory address with a predetermined time difference.
