  • Patent number: 11929378
    Abstract: A light detection device includes: a back-illuminated light receiving element; a circuit element; a connection member; an underfill; and a light shielding mask. The light shielding mask includes a frame having an opening and a light shielding layer formed on an inner surface of the opening. A first opening edge on the side of the circuit element in the opening is located at the outside of an outer edge of the light receiving element. A second opening edge opposite to the circuit element in the opening is located at the inside of the outer edge of the light receiving element. The opening is narrowed from the first opening edge toward the second opening edge. A width of the frame increases from the first opening edge toward the second opening edge. The underfill reaches a gap between the light receiving element and the light shielding layer.

  • Patent number: 6609232
    Abstract: In logical compound of inter-subblock paths, circuits including all inter-subblock paths are generated. Logical compound is conducted for the generated circuits to achieve logical compound of the inter-subblock paths. By treating inter-subblock paths as intra-subblock paths, no input/output delay restriction is required for the logical compound of inter-subblock paths. This makes it possible to fully use performance of the logical compound tool, and hence the inter-subblock paths can be optimized through one operation of the processing.

  • Patent number: 5832303
    Abstract: A large-scaled interconnection switch in which a plurality of data processors are interconnected to perform data transfer between one another. The switch includes communication controllers, one provided for each of the plurality of data processors, divided into groups, for controlling communication between the data processors. Each group of communication controllers is connected by a signal line having a multiple bit width. A switch arbiter for arbitrates switch setting requests for interconnection of the data processors from the communication controllers to output a switch setting control signal. The switch also includes bit slice switches having a predetermined bit division count and to which respective/output signal lines are connected which bit-divide input/output signals of the communication controllers.

  • Patent number: 5285448
    Abstract: In a system control information transmission system in a ring LAN system, each of a plurality of data transmission devices transmits a transmission frame including a user information transmission area and a system control information transmission area to an adjacent data transmission device at peculiar periods independent of the state of the system, i.e., a failure in the system. The system control information transmission area in the transmission frame is used to transmit system control information only required to be relayed to a downstream data transmission device.
