Title: Loop form local area network
Inventor: MINAMI TAKATOSHI
Filed: 1986-03-17
Abstract: PURPOSE:To miniaturize the transmission delay to improve the reliability by applying the communication between terminals connected to the transmission line via a double loop transmission line of the shortest distance, dividing the time slot constituting the time division multiplex frame into two regions on the line and assigning the result to each of the lines. CONSTITUTION:One time slot is divided into two regions, a slot 72 is assigned for the system 1 and a slot 73 is for the system 0. In the case or two-way communication between terminal equipments 3a, 3b, nodes 2a, 2b use a terminal interface section 28 to select the lines #0, #1 of the systems 0, 1 for communication so as to minimize the communication delay between terminal equipments. If a fault takes place in the line, then the nodes 2a, 2b change over each matrix switch 25 so that the outgoing line of the line #0 is subjected to loopback to the incoming line of the line #1 and the outgoing line of the line #1 is subjected to loopback to the incoming line of the line #0 respectively. Thus, the signal of the system 0 from the terminal equipment 3a is given to a terminal equipment 3b via a line #1 and the signal of the system 1 from the equipment 3b reaches the terminal equipment 3a via the line #0.

Title: Vane-type oscillating actuator
Inventor: FUJITANI HIDEJI
IPC: F15B15/12
Filed: 1989-03-09
Abstract: PURPOSE:To obtain direct installation of an apparatus on the output side and ensuring a space, which wiring and piping for the apparatus go through, by providing, on a shaft, a vane, which is located at the axial center part and formed into an annular and recessed shape with respect to a cylindrical part, and providing, to a body a stopper and an installing surface, which turns its back to the shaft installing surface. CONSTITUTION:Installing surfaces 1c and 4c turn their backs to each other. Therefore, with one installing surface defined as a fixed surface, an apparatus on the output side can directly be installed to the other installing surface. As a result, the apparatus on the output side can be installed in the form of 'block build'. In addition, since wiring and piping necessary for the apparatus on the output side can go through a cylindrical part 1a, the wiring or piping for the apparatus on the output side does not disturb any assembling work, and a clean appearance can be obtained. Further, by providing a cylindrical part 1a at the axial center part of a shaft 1, where the torque of a vane 3 is small, a decrease in the torque of an oscillating actuator due to the formation of the cylindrical part 1a can be lessened. In addition, since both ends of the vane 3 in the radial direction are supported by both cylindrical part 1a and an outer part 1b, which are formed as an integrated body with the vane 3, the strength of the vane 3 can be made large enough. In addition, since the sealing range can be made small, sealing work can be made simple.

IPC: G06F3/023
Filed: 1980-04-30
Abstract: PURPOSE:To improve the reliability in a tablet device by performing the page detection of books extremely easily based on a capacity change. CONSTITUTION:When it is assumed that the book sheet 331 of a book 32 is selectively operated and is opened in the direction (a), no conductors are affixed to the sheet 331 and therefore the constitution of a capacity part 24 in a detecting part 12 is only the pole plate pair 22. On the other hand, when a book sheet 332 is selectively operated and is opened in the direction (a), the constitution of the part 24 is now the pair 22 and a conductor 23. The capacity part 24 of this time is regarded series connection of the capacity C1' consisting of one (conductor 211) of the pair 22 and the conductor 23 and the capacity C2' consisting of the conductor 23 and the other (conductor 212) of the pair 22. In either case, the capacitive impedance differs largely with the case which the conductor 23 exists in the book sheets and the case in which it does not exist, and the signal of an oscillating circuit 11 can be detected in the detecting part 12.
