Filed: 1989-07-06
Abstract: PURPOSE:To enhance reliability by constituting an IC card so that at least the part excepting the contact terminal effective part of the terminal part of the IC card is divided into a plurality of regions. CONSTITUTION:The dotted line frames C1 - C8 shown in a contact terminal are contact terminal effective parts prescribed according to JIS.

Title: Vibration control and vibration excitation device
Inventor: KATSUURA HIROSHI
IPC: E04H9/14
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To simultaneously execute function as a vibration control device while a structure is excited by the vibration control device by inputting output of the controller of the vibration control device, inputting output of a transmitter, and calculating vibration control force or vibration excitation force therein to be output to an actuator. SOLUTION: The vibration of a target structure vibrated by receiving disturbance is detected, and feedback is performed on the target structure through a controller. In the case where excitation is performed herein, vibration excitation force (f) is inputted from a transmitter before control force (u) is inputted so that the vibration excitation force (Q and the control force (u) are simultaneously input. In the case where it is used as the vibration excitation device, only the vibration excitation force (f) is inputted as spring constant Kc=0 and the control force u=0 temporarily by a computer calculating the control force (u). In the case where the vibration control is performed as soon as the vibration excitation, the spring constant Kc of the controller is returned to an original value to calculate and input the control force (u).  Furthermore, in the case where it is functioned as only the vibration control device, input signal = 0 is performed from the transmitter.
