Title: Hit checker
Inventor: YAMAMOTO HISASHI
IPC: G01R31/04
Filed: 1990-01-29
Abstract: PURPOSE:To detect a high speed hit by applying an impact to the connecting part of a cable to be measured and a terminal to be measured to generate the hit with the use of a high speed digital pulse as a reference signal and detecting the existence of a digital signal. CONSTITUTION:When a pulse signal is generated from a pulse generator 1, one signal is sent to a comparator 5 as a pulse signal A, the phase of which is corrected by a phase correcting device 4, and another one is waveform- rectified by a waveform rectification device 3 through the cable 20 to be measured and sent to the comparator 5 as a pulse signal B. A phase adjustment is made for the signal A by the phase correcting device 4 so as to eliminate the delay time difference between the pulse signal A and B, and a distortion of the output waveform caused from the impedance difference of cable 20 is rectified by the waveform rectification device 3. When the impact is applied to the terminal 2 to be measured and the hit is generated in the cable 20, a part of the pulse signal B is missed and this is detected as a noncoincident signal C by the comparator 5. This signal is latched in a latch circuit 6 to generate a signal D, thereby the hit in the order of nS can be detected.

Title: Overcurrent preventing circuit for contactless switch
Inventor: SUZUKI SHINICHIRO
IPC: H03K17/08
Filed: 1987-01-30
Abstract: PURPOSE:To prevent malfunction due to noise by providing a buffer circuit between a timer capacitor and a transistor (TR) so as to bring the potential of a capacitor in the normal operating state near the stabilized power supply voltage and into the steady-state thereby providing a margin with a lower limit threshold value of a Schmitt trigger circuit. CONSTITUTION:In selecting a voltage Vreg of a stabilized power supply 2 as 2.4V, the upper limit threshold value at the base of a transistor (TR) 43 is 1.6V and the lower limit threshold value is nearly 0.7V. Nearly 1.6V and 0.7V are threshold values to the timer capacitor 18. The potential across the capacitor 18 reaches the steady-state by bringing the voltage Vreg of the stabilized power supply 2 up to the voltage VCE of the constant current source 38. At the detection of an overcurrent, a potential across a resistor 19 reaches nearly 0.7V, then the capacitor 18 discharges its electric charge. Even when noise is detected by the resistor 19 and discharged, noise is interrupted till the voltage is not discharged near the voltage Vreg of the stabilized power supply up to 0.7V. Thus, malfunction of the circuit due to noise is prevented.

Title: Plate spring
Inventor: KOMADA SATOSHI
IPC: F16F1/18
Filed: 1987-01-30
Abstract: PURPOSE:To lengthen a deformation stroke, to accomplish rectilinear propagation ability and to simplify the structure by providing a plate spring comprising three arm portions, that is, at least two arms extending in the radial direction, a circular-arc arm extending right and left from the forward end thereof and an arm extending from both ends thereof toward the central 1 fitting portion. CONSTITUTION:A plate spring comprises at least two first arms extending from the central fitting hole 2 at equal intervals in the radial direction, a circular-arc second arm 4 extending right and left from the forward end of the first arm and the third arm 5 with fitting holes 6, extending from both ends of the second arm towards the central fitting hole 2. When the central fitting hole 2 is fixed to a reciprocating rectilinear moving shaft of a linear motor or the like and the fitting holes 6 of the arm 5 are fixed to a frame, the relative motion is permitted in the direction of board thickness. As the plate spring is thus formed by three arm portions, the lengths of the arms can be increased equivalently and the deformation stroke can be lengthened. As the shape of the plate spring is symmetrical, it has a large rectilinear propagation ability, and as the plate spring is formed by one sheet plate, the structure can be simplified.
