  • Patent number: 5335180
    Abstract: A control method for a moving body and facilities is comprised of steps of measuring and recognizing at least one of the states such as the number of a moving body, moving speed and moving direction, and changing the state of facilities which is a goal of the moving body based on the result of the measurement/recognition, or displaying the state of the facility. A control apparatus for a moving body and facilities is comprised of a measuring unit for measuring at least one of the states such as the number of a moving body, moving speed, and moving direction, a memory unit for storing information on the condition of a local area in which the moving body is moving or on the facilities said moving body is heading for; an arithmetic unit for processing information from the measurement unit and memory unit; and an input/output unit for accessing information processed by the arithmetic unit, and displaying the information.

  • Patent number: 5065335
    Abstract: A decoding type select logic generating method includes the steps of listing on a group basis input signal names and output destination signal names contained in register transfer descriptions and control codes for commanding execution of the register transfers for each of the same input signal names and same output destination signal names, simplifying logics by replacing the control code having the hamming distance of one by a bit meaning "don't care" on the group basis, generating AND gates for the control codes and the input signal names in each of the groups having the same input signal name and combining the outputs of the AND gates, generating AND gates for the control codes in each group having the same output destination signal name and combining the outputs of the AND gates for each of the output destination signal names, and combining the outputs of the groups each having the same input signal name and the groups each having the same output destination signal name.

  • Patent number: 4787597
    Abstract: Concrete forms comprising a first cloth sheet permitting surplus water and air contained in concrete cast in the form to pass therethrough but capable of blocking the passage of the concrete, a second cloth sheet permeably secured to the first sheet, permitting the surplus water and air to pass between and through the first and second sheets and to be absorbed into the second sheet as well as the first sheet, and a support plate to which the second sheet is bonded as by adhesive or thermal bonding acting through only part of the thickness of the second sheet, leaving as water and air permeable throughout the remainder of the second sheet, all of the first sheet, and the interspace therebetween, such being effective as flow paths for surplus water and air to exhaust from the concrete cast in the form to thereby shorten the cure time and improve the strength of the concrete when cured.

  • Patent number: 4730805
    Abstract: A form for forming concrete comprises a first sheet permitting surplus water contained in the concrete cast in the form to pass through the first sheet, but capable of blocking the passage of the concrete, a second sheet secured to the first sheet, permitting the surplus water to be absorbed into it, and a plate secured to the second sheet. The first sheet provides paths for the surplus water by the existence of the second sheet. The paths for the surplus water are ensured by a spacer provided between the first sheet and the plate in lieu of the second sheet or together with the second sheet.
