In a check-out system, in which a purchaser himself who intends to purchase commercial products performs a check-out processing, having a commercial product casted portion, a stocker for stocking the commercial products, a transport unit for transporting the commercial product from the commercial product casted portion to the stocker, and a commercial product identifying unit located between the commercial product casted portion and the stocker for identifying the commercial product transported from the commercial product casted portion, the commercial product casted portion is provided with a commercial product code inputting unit for inputting a commercial product code, and a commercial product detecting unit for detecting that the commercial product is put on the transport path, and the commercial product identifying unit is provided with a commercial product code reading unit for reading the commercial product code of the commercial product being transported; and a first mode in which when the commercial product detecting unit detects that the commercial product is put on the transport path, the commercial product of interest is started to be transported, and in accordance with the identification result provided by the commercial product identifying unit, the commercial product is selectively transported to either the stocker or the commercial product casted portion, and a second mode in which after the commercial product code has been input by the commercial product code inputting unit, the commercial product of interest is started to be transported, and also in accordance with the identification result provided by the commercial product identifying unit, the commercial product is selectively transported to either the stocker or the commercial product casted portion are provided.

A semiconductor integrated circuit device such as a memory device with logic function comprises a plurality of RAM macrocells and gate arrays. The RAM macrocells are constituted by bipolar CMOS RAMs having a total memory capacity of at least 100 kilobits, and the gate arrays contain at least 4000 gates. The logic circuits in the memory device with logic function or the like are constructed by selectively combining CMOS, bipolar CMOS or ECL gate circuits depending on the output load capacity, transmission characteristic requirement, power dissipation and required layout area. The level of signals at various circuits is set to the ECL level or MOS level depending on the local circuit configuration and other factors. The memory device further incorporates sequence control circuits required to be installed downstream of buffer storages of computers.

Attempts have been made to increase the number of pins of packages accompanying the trend toward fabricating integrated circuits highly densely and in smaller sizes. The present invention provides technology for improving reliability in fabricating packages of the surface-mounted type that have increased number of pins. That is, when the packages are mounted on the wiring substrate, the lead pins that receive load from the axial direction exhibit bending strength which is smaller than the junction strength of solder at the junction portions. To achieve this object, the lead pins are made of a material having large resiliency such as a fiber-reinforced material, a transformation pseudo elastic material, an ultra-high tension material, or a heat-resistant ultra-high tension material.

An input/output control system includes an external data controller connected to a plurality of input/output units, a central processor, and a main storage accessible from the external data controller and the central processor. The main storage has a storage area corresponding to each input/ouptut unit and a storage area storing information to arrange a queue for a plurality of priority classes for determining the start priority of each input/output unit. At execution of a start instruction, the central processor sets a control information of the input/output unit to an associated storage area of the main storage and updates the queue arrangement information. The external data controller starts an input/output unit registered to a queue having the highest priority. The start operation is achieved according to the control information of the input/output unit stored in the main storage.

Priority control architecture for input/output operation

In a loop network system in which a plurality of nodes are connected in the form of a loop, and a token frame is transmitted to shift the data transmit right among the nodes, the token frame transmitted from a node includes information for reserving the data transmit right of its own node even after allocation of the data transmit right to another node, so that a full duplex communication linkage can be established between the node having acquired the data transmit right by receiving the token frame and the node having transmitted the token frame. The token frame further includes a level mask field specifying the data transmit right allocation level so that the data transmit right is shifted according to the allocation level.
