Abstract: In a method of communicating between an ATM-UNI and a LAN in a communication apparatus, which has an ATM-UNI interface and a LAN interface for performing communication between these interfaces via an ATM switch, transmission data in an ATM-cell format is received from a terminal connected to the ATM-UNI interface to a terminal connected to the LAN interface. The ATM cells are accumulated in a buffer memory provided in the ATM-UNI interface and assembled into a frame. Completion of reception of all ATM cells of one frame is recognized and it is determined whether there is margin for a transmission by referring to a status of vacancy of a LAN interface corresponding to the other party to communication. One frame of the ATM cells accumulated in the buffer memory is transferred to the LAN interface corresponding to the other party via the ATM switch in a case where there is margin for transmission. The ATM cells are converted into a frame at this LAN interface and the frame is sent to a LAN terminal.

Abstract: A sheet ceramic package includes a plurality of product units, such as ceramic substrates and circuit substrates for semiconductor devices. The individual product units can be separated from the sheet ceramic package by breaking them apart along snap lines. Each product unit has inner layer conductors for providing external connections to a semiconductor to be packaged therein. A dummy part, with conductor patterns for evaluating the electrical characteristics of corresponding units, surrounds at least partially the periphery of each product unit. Exposed conductors of the product units and the dummy parts are plated by means of electroless plating allowing the product units to be electrically independent of each other because of the absence of the need to apply a uniform plating potential. Semiconductors are packaged into the individual product units and are hermetically sealed.

Abstract: The present invention relates to an arrayed recording apparatus with reduced writing time. Various devices are used to write data without redundant data and to update the redundant data more efficiently during idle time. In one embodiment, a temporary write track is provided for each cylinder. When data are read, updated and re-written, the data are re-written to the temporary write track. Since the re-writing does not require a full disk rotation, the writing occurs quickly. Data in the temporary write track are relocated into the disk during an idle state, without being synchronized. Additionally, corresponding blocks in data areas can be used for writing data rather than a specified temporary write track. In order to improve re-writing time, the rotation of the disk drives can be synchronized to avoid full rotations between reads and writes, or cache memories for each disk can be used.
