Abstract: The invention provides an electronic component feeding device which can stably feed electronic components, and an electronic component mounting apparatus having the electronic component feeding device. In a component feeding unit, an opening provided in a suppressor for picking electronic components is formed in a size corresponding to electronic components stored in a storage tape of 16 mm pitch so as to employ storage tapes of four types, i.e., 4 mm pitch, 8 mm pitch, 12 mm pitch, and 16 mm pitch. When the storage tape of 4 mm pitch is employed, a component pickup position of a suction nozzle and a feed stop position of a head electronic component have been conventionally in a center of the opening.

Abstract: A connector having a floating structure includes a floating holder 4 for coupling a fitting coupling portion 5 connected to a portable electrical apparatus 30 to a base 3 through a floating mechanism 10. The floating holder 4 is molded of plastic as a separate part from a connector main body 2 provided with the fitting coupling portion 5. The floating holder 4 has a first holder 4A and a second holder 4B for pinching and supporting a coupling deck 8 of the connector main body 2 from opposite sides. The first holder 4A and the second holder 4B have locking hooks 18, 19 and are coupled to each other directly or through the connector main body 2. Moreover, the first holder 4A and the second holder 4B have integrally molded support portions 16, 22 for supporting the coupling deck 8 of the connector main body 2.

Abstract: In a communication network, routers are interconnected in a hierarchical tree structure and local network nodes are connected to each of the routers located at the lowest level of the tree structure. A network monitor is connected to one of the routers which is located at the top of the tree structure. Each router comprises a first memory having a plurality of entries and a second memory. In response to a packet from the network, a physical address and a corresponding logical address are mapped in one of the entries and a predetermined timer value is set. The timer value is decremented at regular intervals. At regular intervals, the first memory is searched for an entry whose timer value is decremented to a predefined threshold and one of the local network nodes corresponding to this entry is polled to receive a response therefrom indicating an operating state of the polled node. The response is stored in the second memory.

Abstract: The present invention sets a first boot record indicating a first file group information on a head address of a non-volatile memory a second boot record indicating a second file group information on an end address of the non-volatile memory without partitioning the non-volatile memory. When accessing to files of first file group, an address is generated based on information on the first boot record. When accessing to files of second file group, an address is generated based on information on the second boot record.

Abstract: In an ATM-LAN communication system, cell assembly disassembly (CLAD) units provide segmentation of a packet received from a LAN into payloads and assembling them into ATM cells, and disassembling received ATM cells into payloads and assembling them into a packet for transmission to the LAN. A connectionless switching function (CLSF) processor receives ATM cells either from an ATM switch and the CLAD units, and includes a database for storing address information of the received ATM cells and rotating the received ATM cells to the ATM switch and the CLAD units according to the address information of the database. The database has a destination address (DA) field, a VPI field and a VCI field.

Abstract: A cell assembly disassembly facility for interconnecting a local area network and an ATM switch includes an address table and a cell buffer for receiving ATM cells from the switch. A cell disassembler, connected to the cell buffer, disassembles the ATM cells into a packet for coupling to the LAN. The source address, VPI and VCI of each BOM (beginning-of-message) or SSM (single-segment-message) ATM cell in the cell buffer are stored into the DA, VPI and VCI fields of an entry of the table. Entries having identical source addresses (SA) are detected. If the same SA entries have different VPIs and VCIs, they are divided into at least two groups of entries. A majority decision is made on the entry groups to determine a winner. If one of the groups is determined to be a winner, the rest of the groups is erased and all the entries of the remaining group are then erased except for one entry.

Abstract: Successive received asynchronous transfer mode (ATM) data cells are stored in a cell reception buffer. All address information included in the received ATM cells in an address table are registered, and the same address information in the address table are updated when there is idle time for a process of assembling packet data from the ATM cells or when there is no empty area in the address table. In a packet reception buffer successive received packet data are stored. The packet data stored in the packet reception buffer are disassembled into ATM data on the basis of address information retrieved from the address table.
