    • An apparatus suitable for digital data transfer with a tape cassette is designed to require no movement of a magnetic transducer head to establish data transfer contact between the head and a tape cassette. The tape cassette is inserted in the apparatus in the direction of a notional line intersecting at right angles the axes of rotation of the pair of hubs of the tape cassette. Upon full insertion in the apparatus the tape cassette has its apertured front side held opposite the transducer head. A cassette shift mechanism subsequently transports the loaded tape cassette in a direction normal to the notional line, into data transfer contact with the transducer head. A tape transport shift mechanism also operates to move a pair of motor driven spindles into driving engagement with the respective hubs of the tape cassette. The insertion of the tape cassette automatically triggers the operation of both cassette shift mechanism and tape transport shift mechanism. A preferred embodiment additionally comprises an ejector mechanism including a pushbutton. Upon activation of this ejector pushbutton the tape transport shift mechanism moves the drive spindles out of engagement with the cassette hubs, and the cassette shift mechanism retracts the cassette away from the transducer head and further ejects the cassette from the apparatus.
    • 适用于带盒的数字数据传输的装置被设计成不需要磁性传感器头的移动,以在磁头和磁带盒之间建立数据传送接触。 磁带盒沿着与磁带盒的一对轮毂的旋转轴线成直角相交的概念线的方向插入设备中。 当磁带盒完全插入设备中时,磁带盒的开孔前侧保持与换能器头相对。 盒式换档机构随后将装载的盒式磁带沿垂直于图形线的方向传送到与换能器头部的数据传送接触。 磁带传送换档机构还操作以将一对电动机驱动的主轴移动成与磁带盒的各个毂的驱动接合。 磁带盒的插入自动触发盒式换档机构和磁带传送换档机构的操作。 优选实施例还包括包括按钮的喷射器机构。 在启动该喷射器按钮时,带传送换档机构将驱动主轴移动离开与盒毂的接合,并且盒的换档机构使盒远离换能器头退回并进一步从装置中弹出盒。

    • Disclosed herein is an improved logic module used for logic emulation along with an enhanced logic emulation board subject to logic verification. The logic module has a plurality of programmable LSIs capable of programming logic and a plurality of switching LSIs capable of programming connections, the LSIs being mounted on one or both sides of a board. Peripheral portions of the board carry connectors for electrical connection to the outside. There are two types of data lines: those directly coupling the connectors to the programmable LSIs, and those linking the connectors to the programmable LSIs via the switching LSIs. The programmable and switching LSIs constitute a crossbar connection arrangement. The logic emulation board has connectors for connection to a logic emulation module, and lands for supporting LSIs targeted for development. Pins of the connectors and the lands are interconnected on a one-to-one basis. Also disclosed here is an upgraded module structure permitting a multiple-stage module setup together with an advanced cooling structure for modules.

    • A packaging method of an electronic component for packaging the electronic component to a packaging substrate comprises the steps of: forming a predetermined quantity of solder bumps at connection portions of the electronic component; forming through-holes and pads on the packaging substrate in such a manner as to correspond to the solder bumps; applying a solder paste to pad portions of the through-holes and the pads formed on the surface of the packaging substrate in such a manner as to attain a specific quantity of solder components with the predetermined quantity of the solder bump; and heating the electronic component and the packaging substrate to a predetermined temperature such that button-shaped connection bumps having a predetermined height are formed between the pads and the packaging substrate so as to connect the electronic component and the packaging substrate and to keep a predetermined gap between the electronic component and the packaging substrate, and cylindrical-post connection bumps are formed between the through-holes and the packaging substrate in accordance with this predetermined gap so as to connect the electronic component and the packaging substrate. In this way, the cylindrical-post connection bumps are formed in association with the button-shaped connection bumps.
