Abstract: A gimbal for a conditioning system for a CMP tool is configured to maintain a conditioning disk in contact with a polishing pad of the CMP tool. The gimbal includes an arm coupling for coupling to a conditioning swing arm of the CMP tool; and a disk holder for holding the conditioning disk. A flexible diaphragm extends between the arm coupling and the disk holder. The flexible diaphragm allows the disk holder to flex relative to the arm coupling. The flexible diaphragm is made of a metal or metal alloy.

Abstract: The present disclosure includes systems and methods for solving speckle problems by exciting the screen with a more complex vibration spectrum. A range of frequencies provides, in effect, a collection of overlapping patterns of high and low displacement, so that all regions of the screen have enough motion to reduce visible speckle. As previously discussed acceptable speckle may be approximately 15% contrast or less, preferably approximately 5% contrast or less at approximately 15 feet from the screen.

Abstract: A diaphragm for a loudspeaker, wherein the diaphragm is formed generally in a closed loop around a central void, the loop lying in a plane, the diaphragm having an axis in a direction orthogonal to the plane along which axis the diaphragm is arranged to be driven in use, the diaphragm having inner and outer circumferential edges which are adapted, in use, to be fixed in position, wherein a substantial portion of the diaphragm between the inner and outer edges is shaped in the direction of the said axis so as to protrude from the general plane of the diaphragm in either or both directions along the axis, and wherein said shaped portion when viewed along the direction of the axis comprises at least one series of curves extending radially across substantially all of the driven area of the diaphragm.

Abstract: Herein taught is an apparatus for producing a continuous sonic boom that is simplified having few components. Namely, a motor, a rotating motor shaft, a rotor and a power source. The rotor is interconnected onto the rotating motor shaft, thus upon energizing, the motor rotates the rotor faster than the speed of sound resulting in production of a continuous sonic boom. Also, the rotor includes various configurations and the tips thereof are variable in shape and size. Furthermore, the apparatus is contained within different types of support means and also we provide a deflective sonic wave focal point projection mechanism.

Abstract: In a speaker including a voice coil which is wound on a voice coil bobbin and is inserted into a magnetic circuit gap of a magnetic circuit, and a cone which is coupled to the voice coil bobbin for vibration, the cone (16) is constructed of two divided cones: a drive cone (16A) linked to the voice coil bobbin (14) and a cone paper (16B) linked through an edge (17) to a frame (F).

Abstract: By forming a flange portion 16a1 protruding inward in the radial direction at an upper end portion 16a of a voice coil 16, a coiling sectional shape of the voice coil 16 is set to a L-shape. And, the upper end portion 16a of this voice coil 16 is bonded and fixed to a central flat portion 12b of a diaphragm 12. Hereby, by only increasing slightly the weight of the usual voice coil having an I-shaped coiling section, the large bonding area can be obtained between the voice coil 16 and the diaphragm 12, so that separation of the voice coil 16 can be prevented. Further, since other portions of the voice coil 16 than the upper end portion 16a thereof have the usual coil thickness, it is not necessary to expand the width of a cylindrical magnetic gap G in a magnetic circuit unit 18, whereby it is prevented that electroacoustic conversion efficiency of a speaker 10 lowers.

Abstract: An automatic washer is provided with a separate motor to drive the drain pump, the motor having a displaceable stator portion connected to the basket brake mechanism such that when the pump motor is energized the basket brake will be released. Such a construction obviates the need for a separate component such as a solenoid to deactivate the brake mechanism. The stator portion is displaceable perpendicularly to the rotor axis and can move either in a radial sliding manner or can be pivotally mounted so as to move through an arc relative to the rotor.
