  • Patent number: 6992250
    Abstract: An electronic component housing package includes a base body made of a metal; a rectangular frame body made of a metal; an input/output terminal made of insulating material, which has line conductor for electrically conductively connecting the interior and exterior of the frame body; and an input/output terminal mounting portion, into which input/output terminal is fitted and which is formed as a notch extending across two adjacent corners of a frame body's lower part. The input/output terminal is so configured that its opposed end-face pair at two corners are made flush with opposed outer-side-surface pair including two corners of frame body, and that metal layer is applied to both of a part of an input/output terminal's end-face extending along the mounting portion and another part thereof extending along the base body.

  • Publication number: 20030115327
    Abstract: The home gateway HGW (1) includes a communication section (31), an authentication function section (32), a directory management function section (33), and a communication path setting function section (34). The communication section (31) receives data transmitted to the HGW (1). The authentication function section (32) authenticates the aforementioned data to be from an authorized user or not. Responsive to a service registration, the directory management function section (33) registers service information, checks the matching between the service information and service permission policies, and requests the communication path setting function section (34) to set a communication path. The communication path setting function section (34) monitors the state of data communication along the communication paths, and closes any unnecessary communication paths that may have been set.

  • Patent number: 5478520
    Abstract: A process and apparatus for effecting injection molding of plastic resin products on an injection molding apparatus including a metal mold composed of a slidable mold element and a fixed mold element defining together the mold cavity, an actuator for sliding the slidable mold element and an injection nozzle for adjusting the nozzle flow path section, which comprises a first molding step of injecting a molten resin into the mold cavity which has been preset by the slidable mold element so as to include a post-compression margin to be compressed afterwards in a second molding step, to effect the injection under a reduced molding pressure, while causing a temperature elevation and, thus, a viscosity reduction of the molten resin, until the mold cavity has been filled up, and a second molding step of compressing the resin so charged in the mold cavity by operating the slidable mold element to compress the charged resin to compensate the post-compression margin, so as to allow an effective pressing force to be imp

  • Patent number: 5392286
    Abstract: Disclosed is a data transmission unit for use in a system wherein data to be transmitted is organized into packets which may be assigned one of four states: idle, occupied, released, or reset. Or these packets may be assigned one of three states: idle, occupied, or released, each state being able to include a reset bit. Each unit has terminals associated therewith and is assigned two windows on the number of packets it may transmit. One window is a parameter for transmitting data by using idle packets and the other is by using released packets. The unit responds to the state of a received packet, the state of the windows, and the presence or absence of transmit data to control whether the packet transmitted out of the unit is a packet from internal transforming buffers, a released packet from a released cell producing circuit, an occupied packet containing data from the unit's own terminals.

  • Patent number: 5339317
    Abstract: A packet communications network for transmitting data between nodes by the use of cell slots circulating the network includes a center node inserted in the ring network for sequentially generating, at a selected rate, first and second types of cell slots interleavingly for transmitting first and second types of data, respectively. Each cell slot has a type code for identifying either one of the first and second types, and a status code for identifying the different status of the cells. Each node detects whether the received cell is the first type or the second type. If the received cell is the first type, it is used for transmitting the connection-oriented data under MARS system. If the received cell is the second type, it is used for transmitting the connectionless data under ATMR system.
