Patent JP-S61107838-A (JP)
Title: Input fault processing system
Inventor: KATO TOSHIRO
IPC: H04J3/14
Filed: 1984-10-31
Abstract: PURPOSE:To generate a fault alarm instantly at bit of an input by applying a self-running clock at momentary interruption of input of a phase synchronizing oscillator to which a clock extracted from a reception signal is applied to a frame synchronizing circuit so as to generate an out of synchronism signal. CONSTITUTION:The reception signal is subject to waveform correction by an equalizing circuit 1, from the output of which a clock CK component is extracted and the component is inputted to a PLL circuit 8. The CK extracted at the circuit 8 is subject to phase comparison 3 with a signal from a VCO5, and its error signal controls the VCO5 via an LPF4. Thus, the output CK of the VCO5 becomes a signal synchronously with the input CK and its output is inputted to a CK input terminal of an FF6 and a frame synchronizing circuit 7. An output waveform from the circuit 1 is fed to the FF6, which identifies the data and gives an output to the circuit 7 while taking timing. If the input signal is interrupted, since the self-running clock of the VCO5 is fed to the circuit 7, the circuit 7 keeps operation normally, generates surely a frame out of synchronism signal and an input fault alarm is raised instantly.

Title: Surge current suppressor
Inventor: SHIMAMORI HIROSHI
IPC: H02H9/02
Filed: 1988-09-16
Abstract: PURPOSE:To prevent surge current by connecting one end of a parallel circuit of an inductance element and a diode element to the first stage joint of a double stage connector end connecting the other end of the parallel circuit to the second stage joint. CONSTITUTION:When the double stage connector of a printed board is connected with a power source line, current flows from the first stage joint through a coil L1 to charge a bypass capacitor C0. When the capacitor C0 is charged upto the source voltage E0, voltage is induced reversely in the coil L1 thus causing overshoot. A diode D1 is inserted in parallel with the coil L1 in order to prevent overshoot. When reverse voltage higher than the voltage at point P1 is produced of point P2 of the coil L1 due to overshoot, the diode D1 conducts to produce voltage drop and the voltage across the capacitor C0 can be suppressed within the sum of the source voltage E0 and the voltage drop VD1 of the diode.

Title: Tubular body
Inventor: KUSUMOTO HARUNOBU
IPC: A63B53/10
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To exhibit a characteristic of twisting in a specific direction when applying a specific bending moment by providing a tubular body with two regions along the longitudinal direction divided by two circular arcs, having a difference in displacement caused by the bending moment, and twistingly deforming about the axis simultaneously with the action of the bending moment. SOLUTION: A tubular body is divided by two circular arcs in its cross section, provided with two regions along longitudinal direction of the tubular body, and constituted of fiber reinforced prepregs whose respective reinforcing fiber directions are different. When the tubular body is bent, a tensile stress is applied on a projecting side (a) and a compressive stress is applied on the recessed side (b). For example, when the fiber direction of the projecting side (a) is +45 deg. to the axial direction and the fiber direction of the recessed side (b) is -45 deg. to the axial direction, the deformation direction (twisting direction) in applying the tensile stress on the projecting side (a) becomes the same direction as the deformation direction (twisting direction) in applying the compressive stress on the recessed side (b).  The deformation is thus strengthened mutually in the whole tubular body and strong twisting deformation is generated in the tubular body.
