Title: Ac line filter
Inventor: TAKAGI KUSUO
IPC: H03H7/09
Filed: 1988-02-29
Abstract: PURPOSE:To expand the noise blocking characteristic toward a high frequency region by suppressing the stray capacitance between input and output terminals and to expand the noise block characteristic toward a low frequency region by increasing the inductance through the winding the windings in a way that part of 1st and 2nd main cores and part of an auxiliary core simultaneously. CONSTITUTION:Since the effective permeability of the auxiliary core 13, especially the effective permeability at a low frequency region is larger than that of the main core, a large inductance is given especially to the lower frequency region thereby improving the characteristic at the low frequency region. Moreover, the winding parts 8a2, 8a3, 8b2, 8b3 where windings are wound on both the main and auxiliary cores are wound concentratedly and densely, the other winding parts 8a1, 8a4, 8b1, 8b4 wound only on the main cores A, B are wound less densely. Thus, the distributed capacitance and the inter-terminal stray capacitance of the winding parts 8a2, 8a3, 8b2, 8b3 are decreased. Even in the event of an ungrounded earth terminal or improper grounding, the effect on the broad band noise blocking characteristic is suppressed.

Abstract: PURPOSE:To enable to operate even at low power supply voltage, by constituting the circuit with the differential amplifier, current source and first to third FET transistor Tr, and obtaining the inversion current for the current source current from the drain of third transistor. CONSTITUTION:The differential amplifier 10 has the function that the potential at point A is equal to that at point B so that the output 11 controls the conduction of FETQ3, and if the potential at point B is increased, the output 11 increases, and if the potential at point B is increased, the output 11 decreases to compensate the potential variation at point B or C. That is, the potential of point C is in agreement with the potential at point B with the negative feedback loop connected from the output of the amplifier 10 to the inversion input terminal - of the amplifier 10 through FETQ3. The matching of the source and drain voltage of FETQ1 and Q2 is remarkably excellent and the matching is kept even to the load and power supply fluctuation connected to the output terminal A of the inversion current, and the potential at point B is the drop only for the gate source voltage of FETQ1 from the power supply. Accordingly, the low power supply operation can be made.

IPC: F16F7/108
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To prevent a cylindrical member made of elastomer from displacing in a circumferential direction and an axial direction by arranging a non-end ring which is formed on the inner circumferential surface of a shaft material inserting hole and which is formed of a material having substantially poor expanding performance on the outer peripheral side of a small diameter part whose diameter size is smaller than the outer diameter of an shaft material. SOLUTION: A dynamic bumper 1 is mounted on the intermediate part of a driving shaft by press-in. The inner diameter size of the inner circumference 3a of a sleeve 3, namely, the inner diameter size D1 of the penetrating hole of the driving shaft is equalized with the outer diameter size of the driving shaft. In the part of a projection 6, a small diameter part which the inner diameter D2 of the part of the projecting 6 is formed smaller than the outer diameter size of the driving shaft is formed. When the dynamic bumper 1 is mounted on the driving shaft, the thickness (a part of the thickness shown by a t size) of the inner circumferential side of a non-end ring 7 including the projection 6 is compressed, and fastening force fastened by a band is acted on the driving shaft.  It is thus possible to fix the dynamic bumper 1 disenably to move in axial direction and a circumferential direction of the driving shaft.
