Title: Electrostatically operated, micromechanical capacitor
Inventor: BAUHAHN PAUL E
IPC: H01G5/06
Filed: 1996-08-20
Abstract: An electrostatically controlled, micromachined micromechanical capacitor having an adjustable, extensive tuning range. One configuration of the microcapacitor consists of a set of rotatable plates (14) adjacent to each other. Another configuration consists of a set of various sized beams or plates adjacent to a common plate or plates. The pairs of plates are rotated or linearly moved relative to each other to provide an adjustable capacitance.  The rotation or movement of the plates is caused electrostatically by an application of a DC or low frequency voltage to the respective plates. The signals that are processed by these micromechanical capacitors are typically in the megahertz range and higher. The process for micromachining the micromechanical capacitor is similar to the process utilized in integrated circuit fabrication.

IPC: B23K11/16
Filed: 1998-03-05
Abstract: When a workpiece which is made up by laminating a plurality of plates of different thicknesses is welded by using a spot welding gun having a pair of electrode tips, the electrode force to the workpiece by one of the electrode tips, which is positioned on the side of a thinner plate, is made larger that the electrode force to the workpiece by the other of the electrode tips. The contact pressure on the side of the thinner plate becomes larger with the result that the contact resistance decreases. Therefore, the nugget on the side of the thinner plate becomes smaller than the nugget on the side of the thicker plate.

Title: Speaker and amplifier system
Inventor: DING CHIH-SHUN
IPC: H04R3/00
Filed: 1996-12-12
Abstract: A sound reproduction system employs an amplifier system and a speaker (40).  The speaker (40) provides two negative feedback signals, one (92) indicative of the current through the speaker voice coil and a second (93) indicative of the velocity of the speaker diaphragm. The velocity signal is provided via feedback path (93) to an input of the amplifier system. The current signal (92) is provided by the second feedback path through a bandpass filter to the amplifier input. The velocity measurement may be derived from a second voice coil (42) coupled to the diaphragm, or may be derived from a piezoelectric sensor coupled thereto. The current signal may be derived from the voltage drop across a resistor (50) placed in series with the speaker voice coil (41).
