Abstract: A transmitting and receiving system includes a first information processing apparatus and a second information processing apparatus. The first information processing apparatus includes a first cache memory, and the second information processing apparatus includes a second cache memory. The second information processing apparatus is configured to transmit and receive information to and from the first information processing apparatus. When transmission information to be transmitted from the first information processing apparatus to the second information processing apparatus is stored in the first cache memory of the first information processing apparatus, the first information processing apparatus transmits partial information that is included in the stored transmission information to the second information processing apparatus or transmits identification information that identifies the transmission information to the second information processing apparatus.

Abstract: First to third steel members are cut to form predetermined planar shapes using press machines and form an upper member, a reinforcement member and a lower member. The carbon content of the third steel member is set lower than the carbon content of the first and second steel members. The upper member, the reinforcement member and the lower member are then assembled. The reinforcement member is superposed on the upper member. The upper member and the lower member are partially superposed. The superposed portions of the upper member and the reinforcement member and the superposed portions of the upper member and the lower member are then respectively joined by spot welding to form a blank member. The spot welded blank member is then heated to a temperature of a transformation point or higher, and the blank member is hot press formed by one press machine.

Abstract: A logical circuit comprises a plurality of stage processing units, each of which includes a logical operation processing unit and a carry signal transmission controlling unit. The logical operation processing unit carries out a logical operation process of plural bits of input data, and the carry signal transmission controlling unit controls transmission of a carry signal which is supplied from a carry signal transmission controlling unit of the preceding stage of the stage processing unit. In this structure, the logical operation process is carried out with every group of plural bits of the input data, and the carrying signal is transmitted through the stage processing units which are less in number than that of a conventional logical circuit, so that the processing time of the logical circuit is shortened.
