Title: Pneumatic vibration apparatus
Inventor: GOTO KATSUHIRO
IPC: F16F13/10
Filed: 2001-10-17
Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic vibration apparatus which has a simple construction, removes a high-order component at a low cost, and enables a suitable vibrating power to be obtained. SOLUTION: A control section 51 outputs a reference signal C corresponding to the frequency and amplitude of a signal from a vibration generation source to a pulse width modulation section 55, wherein a drive control signal K due to pulse width modulation is generated and basing upon the drive control signal K, an solenoid valve 45 is on-off controlled. Thus, the connection of an air chamber X1 to the air suction port 41 side and to the atmospheric air side is alternately switched. The drive control signal K is generated by pulse width modulation corresponding to the amplitude of the reference signal C and comprises at least the same number of pulses corresponding to the duty change frequency per period of the standard signal. The drive control signal K is synchronous with the standard signal S.  The number of pulses of the drive control signal K per period of the control signal is changed according to the control frequency of the standard signal, and the product of the number of pulses and the control frequency is the same as or less than the responsive frequency of the solenoid valve.

Title: Electromotive wheelchair
Inventor: MATSUBAYASHI TORU
IPC: A61G5/04
Filed: 2001-10-17
Abstract: PROBLEM TO BE SOLVED: To provide an electromotive wheelchair equipped with an angle-of- inclination estimation means capable of accurately estimating the inclination of a road surface during running without requiring a special addition device. SOLUTION: The respective drive currents I (1) and I (2) of independent motors M1 and M2 driving the drive wheels 3 and 3 on both sides of a car body 2 are detected, and the inclination of the road surface is estimated on the basis of the synthetic load torque represented by the sum total I=I (1)+I (2). Since the load torques acting on both drive wheels 3 and 3 are synthetically evaluated to estimate the inclination of the road surface, even if the load torques of the left and right drive wheels 3 and 3 do not coincide with each other by the movement of the center of gravity of the electromotive wheel chair 1 on a slope, or the load torques of the left and right drive wheels 3 and 3 do not coincide with each other by the revolution of the electromotive wheelchair, the inclination of the road surface can be properly estimated.
