    摘要: An active noise controller can determine the signal transmission characteristics from the power amplifier and the speaker to the microphone without using any special external measuring instrument and calculate a cosine correction value and a sine correction value without using an external computer. The active noise controller uses the cosine correction value and the sine correction value to actively reduce vibrational noise. The measurement mode is selected on touch panel (3), and correction value calculator (22) calculates cosine correction value C0 and sine correction value C1 by using filter coefficients W0 and W1 which allow error signal e′(n) to approach zero. Memory (23) stores these values C0 and C1.

    摘要: An active noise reducing device includes switchover frequency memory which stores a speaker having weaker influence of level drop or dips in gain characteristics of transmission from first speaker and second speaker both working as secondary noise generators to microphone working as a residual signal detector, and also stores a frequency band of that speaker. Output switcher appropriately and selectively switches first speaker over to second speaker in response to the noise frequency at present calculated based on the rpm of engine by frequency calculator. This structure allows the active noise reducing device to work steadily even if level drop or a dip occurs in the gain characteristics of transmission from the speaker to the microphone, and allows suppressing the occurrence of abnormal sound due to divergence or distorted sound due to excessive output. Ideal noise reduction effect can be expected.

    摘要: The method of adhering polishing pads is capable of easily exchanging polishing pads in a comfortable posture. The method comprises the steps of: setting a pad adhering carrier, which has a through-hole in which a roller unit for pressing polishing pads is fixed, in a holder with arranging a roller unit in a radial direction of a lower polishing plate and an upper polishing plate; relatively moving the upper polishing plate toward the lower polishing plate so as to clamp the roller unit between the lower polishing plate and the upper polishing plate with a prescribed force; rotating the lower polishing plate and the upper polishing plate, which clamp the roller unit, in the opposite directions at the same speed; and pressing the polishing pads onto polishing faces of the lower polishing plate and the upper polishing plate by the roller unit.

    摘要: The method of adhering polishing pads is capable of easily adhering the polishing pads without damages. The method comprises the steps of: tentatively adhering the polishing pads to polishing plates; attaching a roller unit having a shaft and a roller member, which is capable of rotating about the shaft and which has a projected section having a prescribed width and spirally formed in an outer circumferential face, on the lower polishing plate in the radial direction; moving the upper polishing plate downward, by the holding unit, until the upper polishing plate contacts the roller member; and simultaneously adhering the polishing pads onto the upper and lower polishing plate by rotating the upper and polishing plates in the opposite directions at the same speed with pressing the roller member by the upper polishing plate.
