Abstract: Without making the address control more complex than necessary, a memory can be effectively utilized by accessing a square memory area. According to a processor of the present invention connected to memory apparatus having a two-dimensional memory area comprised of rows and columns, the processor comprises registers for storing a start address, an end address, and a number of columns per row of a square area on the memory. The registers are used to generate access addresses for accessing the square area. The processor is provided with the address generation and control unit for outputting the generated access addresses. The address generation and control unit includes a modulo addressing control unit for generating the access addresses for cyclically accessing the square area. A square circulation mode information decides whether or not to access cyclically the square area. Based on a value of the square circulation mode information, whether or not to cyclically access the square area is decided.

Abstract: A 1-port type surface acoustic wave device can be produced by using the same tools as used for the production of a 2-port type surface acoustic wave device and achieves a substantial improvement in terms of impact resistance. A 1-port surface acoustic wave resonator includes a surface acoustic wave substrate, two dummy bump electrodes and two input/output bump electrodes disposed on the surface acoustic wave substrate adjacent to a plurality of input/output extraction electrodes.

Abstract: The active matrix type liquid crystal display device has a plurality of liquid crystal elements. Each liquid crystal element has a transistor section, a transistor side conductive light shielding film electrically connected to the transistor section, and a liquid crystal element having an opposing electrode coupled to the transistor section. There are a first potential terminal connected to the opposing electrode and a second potential terminal connected to the transistor side conductive light shielding film with a potential applied by the first potential terminal being independent from a potential applied by the second potential terminal. With this arrangement, the lateral field components around the pixel portion, which become a cause for the reverse tilt of the liquid crystal, are relatively reduced with respect to the vertical field components, thus reducing the disclination and providing excellent display characteristics without residual images.

Abstract: Air-cleaning filter element prepared by applying a pressure-sensitive adhesive agent to at least a pair of three-dimensionally mesh-structured elastic-flexible webs, disposing evenly an adsorbent material, such as activated carbon, in a size range of 0.5 mm to 10 mm in diameter between said pair of elastic-flexible webs and pressing the same elastic-flexible webs together as superimposed. The air-cleaning filter element is free from such a deterioration of the adsorbent material as caused by an adhesive and any significant fluid pressure drop on passage of fluid.
