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.

The method of polishing a work is capable of reducing a polishing cost, polishing a surface of the work with high polishing accuracy and easily disposing used polishing liquid and used washing liquid. The method comprises the steps of: pressing the work onto a polishing member; feeding polishing liquid; and relatively moving the work with respect to the polishing member. Electrolytic reduced water produced by electrolyzing an electrolyte solution is used as the polishing liquid.

In an active noise control apparatus in which an audio signal and a noise control signal are mixed to thereby sound a loudspeaker inside a motor vehicle, a general-purpose audio head unit cannot conventionally be freely changed for the one already mounted on the motor vehicle. As a solution, an active noise control unit is provided with a buffer amplifier and a mixer. An audio signal amplified by a power amplifier in an audio head unit is adjusted in level by the buffer amplifier such that a level of an audio signal outputted after amplification by the first amplifier becomes substantially equal to a level of the audio signal outputted from the audio head unit. Then, at the mixer, a noise control signal outputted from an active noise controller is added to an audio signal outputted from the buffer amplifier. Therefore, any audio head unit can be freely changed for the one already mounted on the vehicle as long as the audio head unit contains therein a power amplifier.

The method of the present invention cleans abrasive faces of an upper abrasive plate and a lower abrasive plate of an abrasive machine. The method is executed by a cleaning device including: a nozzle for jetting water; a brush for preventing the jetted water from scattering in the air, the brush enclosing the nozzle; and another brush for closing a gap between the preventing brush and an outer edge of the upper abrasive plate, the method is characterized by the steps of: jetting water from the nozzle toward the abrasive face of the upper abrasive plate; moving the nozzle toward the outer edge of the upper abrasive plate; and closing the gap by the closing brush when the gap is formed between the preventing brush and the outer edge of the upper abrasive plate.

In the polishing system of the present invention, a adhering unit adheres a wafer on a carrying plate using liquid. A polishing unit polishes the wafer using a polishing plate. A feeding unit conveys the carrying plate from the adhering unit to the polishing unit. A dismounting unit removes the wafer from the carrying plate. A first discharging unit conveys the carrying plate from the polishing unit to the dismounting unit. A cleaning unit cleans the vacant carrying plate. A second discharging unit conveys the carrying plate from the dismounting unit to the cleaning unit. A third discharging unit conveys the carrying plate from the cleaning unit to the adhering unit. The units are formed into a loop lines so that the carrying plate is circulated in the loop line and the wafers are polished therein.
