Title: Vibration control reinforcement of existing building
Inventor: ISODA KAZUHIKO
IPC: E04H9/02
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To achieve vibration control reinforcement of an existing building by holding a movable support between the upper side and lower side of a pair of cut existing columns and mounting a damping device by making the device stride over existing walls of the existing columns which are cut in the same level as the existing columns. SOLUTION: Existing wall columns 1, 1 are horizontally cut, making an existing wall 5 between columns bear shaft force, and an upper column 2 and a lower column 3 are formed. Next, a movable support 4 is held between an upper column 2 and a lower column 3 and is made to bear shaft force that the support 4 originally bears again. Subsequently, the existing wall 5 between columns is horizontally cut and divided, and an upper wall 6 and a lower wall 7 are formed. Lastly, a damping device 8 is arranged by making the device 8 stride over the upper wall 6 and lower wall 7 and the device 8 is mounted and fixed on/to each of the upper and lower walls 6, 7 with anchor bolts, etc.  In this case, because shearing stress corresponding to horizontal force which is applied to the existing wall 5 can be arbitrarily set by the adjustment of the damping device 8, excess stress is not applied to the existing wall 5. Therefore, a vibration control wall which is larger in absorption efficiency of earthquake energy can be made, making the most of the existing wall 5.

Abstract: PURPOSE:To enable a sampling equivalently at a high frequency by generating a sampling pulse being delayed sequentially from a reference clock. CONSTITUTION:An analog signal applied to an input terminal 9 has a level thereof supported by a sample holding circuit 1. The circuit 1 receives a sampling pulse from a delay circuit 4 to sample an analog signal in response to the pulse.

An output of a reference clock generation circuit 3 is applied to the circuit 4 and an A/D conversion starting signal generation circuit 11. Here, based on the moment at which the A/D conversion starting signal is received, the circuit 4 delays a delay value of a reference clock sequentially to be outputted as a sample signal of the circuit 1. At the same time, the circuit 4 generates an A/D conversion activating signal delayed slightly from the sample signal to be sent to the circuit 2. The circuit 2 converts a value sampled and held into digital from analog.
