Title: Open line detection circuit
Inventor: YOSHIMURA KAZUO
IPC: H04B3/46
Filed: 1979-04-17
Abstract: PURPOSE:To electrically separate the communication circuit and the detection part and to make it possible to detect disconnection of a DC circuit without giving an influence to the communication circuit, by exclusively turning ON and OFF two photocouplers mutually in accordance with a signal current on the line. CONSTITUTION:Transistors TR 10, 11 are exclusively subjected to ON and OFF control mutually by control signals 12, 13 corresponding to a DC data to be transmitted to the line 16. The photocouplers 22, 26 connected between the emitters of TR10, 11 and the electric power source are turned ON and OFF in the same way, after ON and OFF of TR10, 11 follow. The NAND gate 27 to which outputs of the photocouplers 22, 26 are connected always outputs a signal of a high level while a normal DC data is being transmitted on the circuit 16. When the circut 16 is disconnected and a signal current by a DC data becomes zero, both the outputs of the photocouplers 22, 26 become a high level, and the gate 27 displays disconnection of the circuit 16 by oututting a signal of a low level.

Abstract: PURPOSE:To provide a field winding capable of generating magnetic field highly uniformly by removably mounting ribs on the surface of a torque tube for defining parallel grooves extending in the axial direction, and disposing a compound superconductor winding in the grooves. CONSTITUTION:Rib pairs 11 and 12, 21 and 22,...81 and 82 are provided on a torque tube 90 having projections extended longitudinally and spaced circumferentially by 90 deg.. These ribs are attached to the torque tube 90 by mechanically bolting the same, by welding or by means of a binder, so that a groove is formed therebetween. Winding is previously heat-treated by diffusion having the same configurations as those of the grooves in which the winding is to be disposed. The winding may be impregnated with epoxy resin if required. The winding contains a compound superconducting body. In order to arrange the winding on the torque tube 90, the winding is first disposed on the projections extending in the direction X and then the ribs 41 and 42 are fixed. The winding is disposed on the opposite side of the tube and the ribs 51 and 52 are fixed. In the same way, disposition of the winding and fixation of the ribs are repeated also in the direction Y. Finally, the winding is disposed and the ribs 11 and 12, 81 and 82 with wedge-like profile are fixed to complete a field winding.

Title: Level converting circuit
Inventor: OOHAMA MASAYUKI
IPC: H03K19/018
Filed: 1983-03-23
Abstract: PURPOSE:To avoid the actuation of a relay for negative polarity power supply when the power supply for TTL signals is extinguished by supplying the positive own bias to the base of a transistor which drives the relay for negative polarity power supply from the power supply for TTL signals. CONSTITUTION:When the TTL signal H/L supplied from a TTL logical circuit is set at an H level, the base voltage of a pnp transistor TRQ of a relay driving circuit 3 is equal to the power supply voltage +V for TTL signals. As a result, the TRQ is turned off and a relay R for negative polarity power supply has no actuation. While the TRQ is turned on when the signal H/L is set at an L level, and the relay R has actuation. Then the power supply for TTL signals is cut off, and the TRQ is turned off when the power supply voltage V is extinguished. Thus the relay R is never actuated. Thus it is possible to inhibit the actuation of the relay R when the power supply for TTL signals is extinguished.

IPC: G01J3/02
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a pole extracting apparatus capable of effectively extracting a desired maximum point or minimum point. SOLUTION: A plurality of maximum points or minimum points which appear on a graph of measurement information are detected (S1-S2). The magnitude of each maximum point is obtained every maximum point (S3). Maximum points arranged in the order of magnitude are displayed on a monitor together with a graph based on a plurality of measured results (S4-S5). An operator designates a desired maximum point out of the maximum points arranged in order (S6). Maximum points larger than the magnitude of the designated maximum point are extracted and displayed together with the graph (S7-S8). When a new maximum point is extracted, processes S5-S7 are repeated (S9). Thus, a desired maximum point can be easily designated, so that working time until a desired maximum point is extracted can be shortened.

IPC: H04L5/14
Filed: 1982-03-27
Abstract: PURPOSE:To convert easily a piece of bi-directional bus into two pieces of buses for transmission and reception respectively, by inhibiting the output of a transmitting signal with the output of an FF which is set by a receiving signal and reset by a tansmitting signal. CONSTITUTION:An FF and an FF' are provided between lines A and A' for a data transmitting terminal which uses an open collector output to a data output and shares the lines A and A' for transmission and reception. The FF and FF' are set when a low level is fed to line receivers R2 and R2', respectively, and line drivers D2 and D2' are inhibited with the outputs of the R2 and R2' to prevent a low level from returning to the remote side. The FF and FF' are reset when the lines A and A' are set a high level respectively to release the inhibition of drivers D2 and D2'. Thus signals of high levels are transmitted in both ways. In this case, a change is possible for a signal of a low level since a low level has higher priority than a high level.
