Title: Direct current two-wire system electronic switch
Inventor: UEDA KENJI
IPC: H03K17/94
Filed: 1980-03-21
Abstract: PURPOSE:To make it possible to switch an operation mode by only changing the polarity of voltage applied to the external terminal, by connecting the output part of the photocoupler which has been connected in antiparallel to the external terminal, between the detection circuit and the output circuit, and switching a signal transfer between both the circuits. CONSTITUTION:When the DC power source 7 is connected in the direction by which the external terminal A and B become positive and negative, respectively, a power source current flowing into the electronic switch passes through the light emission diode 4P at the input side of the photocoupler. And, the phototransistor 4S conducts, and the output terminal 1c of the detection circuit 1 is connected to the input terminal 2a for normal-open of the output circuit 2, therefore the electronic switch is operated by a normal-open mode. When the electric power source 7 is connected so as to change the polarity of voltage applied to the external terminal, a power source current passes through the light emission diode 5P in the opposite direction, therefore the phototransistor conducts, the output terminal 1c and the input terminal 2b for normal-close are connected, and the switch is operated by a normal-close mode.

Abstract: PROBLEM TO BE SOLVED: To reduce the vibrational response of a structure more effectively at an earthquake or like by switching the damping coefficient of a variable damper so that the vibration of an additional aseismatic element such as a brace is employed or increased for higher damping force. SOLUTION: On receiving information, or oil pressures P1 and P2 in hydraulic chambers 5a and 5b defined in left and right and a relative displacement δ1 of a piston 3 to a cylinder 2 inside a variable damper, a controller 8 feeds a control command to a flow control valve 7 depending on these data.

The damping coefficient C of the variable damper is controlled such that its damping force is increased while the vibration of the additional aseismatic element is increased.  In parallel to the flow control valve 7 of the variable damper, a relief valve 10 is arranged to prevent the additional aseismatic element from suffering an excessive force when the damping coefficient is changed over from the minimum value Cmin to the maximum value Cmax .
