IPC: B63B43/00
Filed: 1994-10-28
Abstract: PURPOSE: To prevent the breakage due to the fatigue of an elastic member for carrying out the reduction of vibration of a main vibration body without deteriorating the vibration reducing effect, by installing a rail having a traveling groove laid horizontally toward one direction between a supporting board and a weight, and a bearing which supports the weight on the supporting board through the turn in the traveling groove in the rail laying direction. CONSTITUTION: The operation direction of a dynamic vibration absorbing device 1 is the A direction, and a ball bearing 5 is not applied with the resistance in the A direction, and moves along a rail 4 having a V-shaped groove. However, in the B direction perpendicular to the action direction of the dynamic vibration absorbing device 1, the V-shaped groove of the rail 4 forms the resistance, and the ball bearing 5 does not move.  Accordingly, a weight 2 vibrates in the A action direction of the dynamic vibration absorbing device 1 according to the vibration characteristic determined by the mass Md and the spring constant Kd of a spring member 3, and the characteristic frequency fd is allowed to accord with the characteristic frequency fA in the direction for reducing the vibration of a main vibration body, and tuning is carried out by varying Md by increasing and reducing the variable weight 2b. Accordingly, the fatigue evaluation is reduced, and the fatigue breakage of the elastic member 3 can be prevented.

Title: Semiconductor storage device
Inventor: IWAHASHI HIROSHI
IPC: G11C11/34
Filed: 1985-11-26
Abstract: PURPOSE:To increase the speed for reading data by charging at both ends of a row line when this line is selected. CONSTITUTION:An address is changed and a row line 11 is selected and driven by the output of a row decoder 13. Thus the line 11 is charged up to the power supply potential VC through an end part A. A MOS transistor TR22 is turned off when the potential of the other end B of the line 11 reaches the potentials lower than the gate potential VD of the TR22 by an amount equal to the threshold voltage. While a pulse generating circuit 23 produces a pulse signal phi every time the address changes and then raises up the gate potential of a MOS TR21 via a capacitor 25. Thus the charging is started with the potential VC at the end B after the TR21 is turned on. Thus the data reading speed of a memory cell 10 set at the most remote position from the decoder 13 is increased. This attains the fast operation of the semiconductor storage device.
