Title: Constant current circuit
Inventor: KONDO HIDEYUKI
IPC: G05F3/16
Filed: 1988-07-27
Abstract: PURPOSE:To cancel the influence of wiring resistances with two current output circuits to obtain an equal output current for each constant current source circuit by constituting a current source circuit of a pair of current output circuits and supplying a common potential to respective common electrode-side connection ends in opposite directions. CONSTITUTION:Ground wirings WGNG and WGNG' of first and second current output circuits 121 and 121' are equalized, and bias wirings WVB and WVB' are equalized, and they are so arranged and wired that intervals of them on layout are equal to those of the connection method between each current source circuit 111 and a common wiring. Consequently, base potentials of transistors TRs Q1 and Qn', base potentials of TRs Q1' and Qn, ground-side terminal potentials of resistances R1 and Rn', and ground-side terminal potentials of resistance R1' and Rn are equalized respectively. Thus, overall output currents I1 and In have the same current value because output currents of TRs Q1 and Qn' and output currents of TRs Q1' and Qn are equal to each other respectively.

Title: X-ray holding apparatus
Inventor: NISHIGAKI SHIYUNICHIROU
IPC: A61B6/00
Filed: 1989-07-21
Abstract: PURPOSE:To make it possible to perform inexpensively a detection by a simple constitution by providing a member movable by a spring force, a balance member the shaft of which is supported with free rotation on one end of this member and wherein each rope hanged on both ends is pressed by the movable member and a detecting mechanism with a switch operated by the movements of the above described both members. CONSTITUTION:A movable block 2a is moved upward and downward by a force of a spring 8 to a supporting member 3a. A balancing bar 4 is supported on a shaft with free rotation under a balanced condition at a top end of the movable block by a shaft supporting part 4a and rollers 5a and 5b are fixed on both ends thereof and two wire ropes 1a and 1b hanged on each roller are pressed by a force from the movable block. When either one of two wire rope is broken, a detecting switch 6 detects the breakage based on movements upward of the movable block and the balancing bar. Namely, when either one of the ropes is broke, a pressing force of the broken rope exercised on the balancing member disappears and the balance of the balancing member is accordingly broken and the movable member and the balancing member are moved. In a breakage detecting part 17c with the above described constitution, breakage of the rope is detected by actuation of the detecting switch.

Title: Defective equalization and discrimination error detecting circuit
Inventor: OKAZAKI KOUJI
IPC: H04B3/04
Filed: 1983-10-07
Abstract: PURPOSE:To obtain a circuit not requiring a series of numerical operations by sampling consecutively data twice at a speed twice the bit rate of the transmission side and comparing the sampled value with a reference value respectively to detect defective equalization and discrimination error. CONSTITUTION:Among data obtained by being sampled with a bit rate twice the transmission rate, data sampled, e.g., timewise earlier takes various values but the data sampled later timewise should be always zero, and if there is a data not 0, it is discriminated that defective equalization or mis-discrimination exists. Thus, when the data is compared with a reference value at a 0/1 discrimination circuit JUD, since the sampled data timewise later is always zero in setting the reference value to a proper value if no defective equalization or mis-discrimination exists, the defective equalization or mis-discrimination is detected by ANDing the data with a clock of the sampling period.
