Abstract: An optical modulator (39) includes a substrate (7) exhibiting an electro-optical Pockels effect and having first and second end surfaces (31, 33) opposite to each other. An optical waveguide (9) of a branched interferometer type is formed on the substrate (7) and has first and second branched waveguide portions (11, 13) with an input end and a reflection side end respectively exposed in the first and second end surfaces (31, 33) of the substrate (7). A modulating electrode (15) is formed on the substrate (7) in a vicinity of the branched interferometer type optical waveguide (9). A reflection plate (35) is mounted on the second end surface (33) of the substrate (7) at an angle of inclination (.theta.) with respect thereto. Still further, a spacer (41) is disposed between a side of the reflection plate (35) and the second end surface (33) of the substrate (7) to thereby define the angle of inclination (.theta.) of the reflection plate (35) with respect to the second end surface (33) of the substrate (7).

Abstract: A bus arbitration system is disposed between a plurality of devices for granting use of a bus having a data bus size larger than a port size of each of the plurality of devices. A plurality of partial buses are made from the full size bus. Each of the partial buses has a data bus size equal to the corresponding port size of the devices, and each of the devices is connected to one of the partial buses through a corresponding port unit. An arbitration between the plurality of devices for granting use of the bus is carried out for each partial bus through the corresponding port unit.

Abstract: Disclosed is a display data transfer control apparatus in which a line control memory which can preset raster count data for modifying, in units of lines, an address of a main storage storing a character font to be displayed and character attribute data are provided, and a transfer line in the character font is determined for each line transfer in a DMA transfer sequence, so that, e.g., multi font control, character vertical elongation control, and ruled line vertical extension control, as well as processing character attributes such as an underline and overline, can be realized in the DMA transfer sequence.

Abstract: A display control apparatus using a bit map method, for controlling character attribute data, such as an underline and an overline. In the apparatus, a line control memory is arranged to preset information of character attributes in units of lines of character fonts to be transferred to a video memory; in a DMA transfer sequence of a DMA transfer controller. Character attribute control is performed in a character controller for each line transfer according to the attribute information read out from the line control memory, and expansion of a character font from a character font memory area to the video memory can be simultaneously performed with processing of character attributes from the line control memory.

Abstract: A video information transfer processing system in which the contents of a video memory are transferred to a main memory device. This system comprises a color extraction circuit including comparison circuits having logical circuits between the video memory and the main memory device and a DMA controller. Each comparison circuit extracts color information to be transferred in response to designated color factor information and the extracted output is supplied to the main memory device. The DMA controller performs timing control, supply of address information and the like in the above-mentioned processing. By using this system, coloring can be carried out during the transference of the video information and a high speed coloring processing is possible.

Abstract: In a communication system comprising a two-wire bus, bidirectional communication is carried out in a time division multiple access fashion through the two-wire bus between a plurality of terminal equipments (26) coupled to the two-wire bus and a central terminator (24) connected to one end of the two-wire bus which has the other end terminated by an active terminator (25). The central terminator transmits, to the two-wire bus, a down burst comprising a down synchronization signal and a down information signal. Each terminal equipment establishes synchronization with reference to the down synchronization signal and thereafter receives the down information signal. The active terminator sends, towards the central terminator, only an up synchronization signal produced with reference to the down synchronization signal extracted from the down burst. Each terminal equipment transmits an up information signal towards the central terminator in the form of an up burst with reference to the up synchronization signal.

Abstract: A parallelepiped housing contains a displacement-transfer plate being slidable along the surface, and a pair of micrometer heads of the same shape and same size are mounted on a rear plate of said housing headed toward the front in said housing maintaining parallel and definite distance to one another.A differential lever is formed in such a length that the pivot parts at each tip of said pair of micrometer heads are rendered to serve as fulcrums, respectively, and a non-bisected part in the lengthwise direction of said lever is rotatably and pivotally supported as a point of application at the said displacement-transfer plate.A rectangular slider block is so constructed as to be guided along side plates and a base plate forming said housing, and is always pulled rearwards by a resilient means. Said slider block and said displacement-transfer plate are fastened via a determined space.Whereby coarse and fine adjustable displacements are realized at the displacement-transfer plate.
