  • Publication number: 20200191066
    Abstract: An intake device for an internal combustion engine includes a valve body and a holding member. The valve body includes a pivot shaft and a valve portion configured to change a passage cross-sectional area of an intake passage. The holding member includes a support portion that pivotally supports the pivot shaft and accommodates the valve body. The holding member is arranged in an inner wall surface of the intake passage. The valve body includes a side wall located between the pivot shaft and the valve portion. The side wall closes a gap between the pivot shaft and the support portion around an entire circumference of the pivot shaft from the intake passage in an axial direction of the pivotal shaft.

  • Publication number: 20090299892
    Abstract: Receipt of an order for a support for transportation in a trade or for documentation in a trade is managed. A control unit of a service management server sends an order receipt information registration screen. In a case where a service pattern is selected on the order receipt information registration screen, the control unit retrieves service plans that constitute the service pattern, and outputs the service plans. Then, the control unit acquires order receipt particulars information about the service plans. Then, the control unit registers order receipt management data. On the other hand, in a case where order receipt information is input in the order receipt information registration screen, the control unit retrieves a service plan that matches the order receipt information, and outputs the service plan.

  • Patent number: 7487119
    Abstract: Image data of a document generated by a key business terminal or a key business server is sent to a database management server, and this image data and the description contents of the document represented by this image data are stored to a freight tracking information database base. Image data and data of the description contents of the document stored in the freight tracking information database are viewed or searched by an authenticated operator who operates a user terminal. Image data representing the progress of transport of goods is sent to the user terminal from the database management server according to the operator's instruction, and an image represented by this image data is displayed by the user terminal.

  • Patent number: 5257271
    Abstract: In a sampled data transmitting apparatus in which the sampled data to be transmitted are divided into odd-numbered samples and even-numbered samples and arranged in different rows of a two-dimensional data array, and in which error correction codes are annexed to each row and to each column of the two-dimensional data array, the row arraying sequence in one of the odd-numbered or even-numbered rows is caused to differ from the row arraying sequence in the other of the odd-numbered or even-numbered rows so that odd-numbered data and even-numbered data continuous with the odd-numbered data are not arranged in one row. In this manner, even when error correction becomes impossible by the error correcting code for one row, interpolation remains feasible because there exist no odd-numbered data or even-numbered data contiguous to each other in the row.
