Title: Pulse signal transmission circuit
Inventor: HIRAGA MASATOMI
IPC: H03K17/64
Filed: 1987-05-19
Abstract: PURPOSE:To increase the input impedance by connecting an output of a logic IC to an anode of a diode via a variable resistor so as to adjust the pulse duty factor of an output pulse signal. CONSTITUTION:A digital signal fed to an input terminal 1 is subject to logical processing by a logic IC 3. The output signal of the logic IC 3 is fed to anodes of diodes D1, D2 via a variable resistor RV. In decreasing the resistance of the variable resistor RV, since a current I1 is increased, the charge storage between the collector and base of a transistor(TR) is eminent, the transient characteristic from the ON to OFF state of the TR is deteriorated, the delay time is increased and the pulse duty factor of the output pulse signal is increased. Since the current I1 is decreased as the resistance of the variable resistor RV increased, the pulse duty factor of the output pulse signal is reduced and no output pulse is generated finally.

Title: Wall damper and its setting method
Inventor: KOBAYASHI NAGAHITO
IPC: F16F15/02
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a high performance wall damper at a low cost by fixing a wall type damper consisting of a plate viscous body vessel to girders of a plurality of upper and lower floors through lever members, and damping a vibration by use of its large interlayer deformation thereof. SOLUTION: This wall damper is formed of a viscous body vessel 4 and its mounting beam 7, a viscous resisting plate 6 and its mounting beam 8, and two lever members 9 as one unit. The wall damper is fixed to girders 2, 3 above and under a girder 15, skipping over the girder 15 for one floor, so that the interlayer deformation of a building extending to two upper and lower floors is utilized to generate the damping force of the damper. When an interlayer deformation is caused in the upper and lower floors by a horizontal force such as earthquake, the deformation corresponding to two floors in total is transmitted to the viscous resistant plate 6, and the displacement speed is also doubled to generate a double damping resistance. The damper is vertically continuously set, and shifted in position when juxtaposed. According to this, the number of dampers can be reduced to reduce cost.
