Title: Band width variable amplifying circuit
Inventor: AMAMIYA IZUMI
IPC: H03G5/02
Filed: 1987-03-10
Abstract: PURPOSE:To make the band width of an amplifying circuit variable by connecting in parallel two pairs of differential amplifying circuits to which the same input signal is supplied, constituting a compound differential pair, and making variable the current ratio flowing at respective differential amplifying circuits. CONSTITUTION:When a control voltage supplied to the base of a transistor 132 of a current variable circuit 13 is made variable, currents I1 and I2 to flow at a first differential amplifying circuit 11 and a second differential amplifying circuit 12 are changed. Based on the change of the current of the I1 and I2, the transition frequencies of transistors 111 and 112 and transistors 121 and 122 are changed, and thus, a band width is changed. In such a case, since the current flowing at corrector load resistances 14 and 15 is always a constant current, a gain as an amplifying circuit is not changed accompanied with the change of the currents I1 and I2. Consequently, the gain of the amplifying circuit is constantly held as it is, and only the band width can be made variable to a necessary band.

Title: Hydraulic damper
Inventor: KITAMURA KENJI
IPC: F16F9/348
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To continue durability by making a sub-valve outer peripheral side adjacent to an inner peripheral side seat part free to seat and unseat a main valve outer periph eral end on and from an outer peripheral side seat part and making a support ener gized by a spring adjacent to a main valve outer peripheral side. SOLUTION: Hydraulic fluid from an extension side port 2a of a piston 2 flows to a pressure surface of a main valve 3 through an opening 3d of a sub-valve 3 and an opening 6a of a support valve 6 at the time when piston speed is fine low speed. At this time, as its hydraulic pressure is low, an outer peripheral end of a valve 4 is not bent, hydraulic fluid from the opening 6a flows in the inside of a ring groove 2e by bending an outer peripheral end of the sub-valve 3 upward around an inner peripheral side seat part 2b as its fulcrum, and extension side damping force is generated.  When piston speed becomes high than low speed, hydraulic pressure of the opening 6a becomes high by a contraction effect of a passage 2f of an outer peripheral side seat part 2c, the outer peripheral end of the valve 4 is bent in such a way as to push down a support 8 by a spring 7, and the extension side damping force is generated. Consequently, as the valve 3 does not work at the time when the valve 4 works, it is possible to prevent early deterioration of valve durability.
