Abstract: A pump fluid passage communicating with an oil pump is formed in main case of a transmission case. Further, a primary fluid passage for supplying a hydraulic pressure to a primary pulley is formed in a wall member of a side case of the transmission case. Further, a line fluid passage for supplying a line pressure to a secondary pulley is formed in a wall member of the side case of the transmission case. Further, a communicating fluid passage is formed in a control valve body. When the control valve body is mounted on the bottom surfaces of the main case and the side case, the control valve body closes the bottom open surfaces of the main case and the side case and at the same time the communicating fluid passage connects the pump fluid passage with the primary fluid passage and the line fluid passage, respectively.

Abstract: The invention discloses a data transmission network having a plurality of data transmission stations connected through a loop-like transmission line for mutual data transmission, wherein a plurality of data frames, each having data packets allocated to the respective stations, are circulated through the transmission line simultaneously, and each station is arranged to send out the data frame to the transmission line immediately after renewing the data of the data packet allocated to that station in the received data frame, and to process the data of the received data frame to be used for the associated equipment after sending out the data frame.

Abstract: An improved method for controlling the rate of deceleration and a point of stopping of a vehicle. Upon passing a first position marker, a first deceleration pattern is produced in an arithmetic circuit for stopping the train at a first predetermined point. Second and third deceleration patterns are produced when the vehicle passes a second position marker. In situations where the first deceleration pattern is a proper one, the vehicle velocity is subsequently conformed to the second deceleration pattern which controls the velocity of the vehicle at a lower deceleration rate than the first deceleration pattern, and stops the vehicle at a predetermined target point.
