Inventor: ARAN JIIN KUIBERU
IPC: E01C19/28
Filed: 1991-05-14
Abstract: PURPOSE: To evaluate the density of a material, and to increase the density by generating a signal corresponding to the vibratory motion of a material contacting member and a signal corresponding to the angular position of a mass, calculating static, dynamic and centrifugal forces applied to the material and generating a signal related to the total of these forces. CONSTITUTION: In a signal conditioning circuit 408 in a control system 400, an electric interface among peripheral devices such as drum/chassis accelerators 401, 402, a forward/backward sensor 410, a distance sensor 412, an eccentric position sensor 414 and the like and a microprocessor 420 is constituted. The microprocessor 420 sends an output signal to a D/A converter 422, and converts it into an analog signal and transmits the analog signal to a servo valve 426 through a driver circuit 424. The servo valve 426 adjusts the flow of the hydraulic pressure of a hydraulic motor 202 driving an eccentric mass, and the speed of the eccentric mass is changed in response to the signal from the microprocessor 420.

Abstract: PURPOSE:To lower the lowest resonance frequency and expands a low frequency reproducing band by providing a DC power source which supplies a current directly to a subcoil provided electrically independently of a voice coil, and flowing a DC currrent so that force in the displacement direction of the voice coil operates on the subcoil. CONSTITUTION:A bobbin 4 is wound with a couple of subcoils 12a and 12b at both sides of the voice coil 4 in the winding direction independently of the voice coil 5. The couple of subcoils 12a and 12b are connected in series so as to have the opposite polarities when wound in the same direction or in series so as to have the same porality when wound in the opposite directions. For example, when an input signal is supplied and the voice coil 5 is displaced downward by DELTAX, one subcoil 12a enters a slope part where magnetic flux density is steep and the force increases. The other subcoil 12b, on the other hand, enters a slope part where magnetic flux density is slow and the force decreases slightly. Therefore, the composite component is force in the displacement direction of the voice coil 5.
