Abstract: A microphone stand structure allows an upper frame rod to be elevated automatically for adjustment to a proper elevation after a locking seat is released. A pressure rod is received and mounted in a hollow main frame rod and includes an extensible member having a top end supporting a bottom end of the upper frame rod movably inserted into the hollow main frame rod such that the whole stand height can be selectively fixed simply locking the locking seat.

Abstract: An image sensor device includes a substrate having an active array region and a peripheral circuit region, a plurality of light-sensing elements disposed within the active array region, a first dielectric layer on the substrate, and a second dielectric layer on the first dielectric layer. A recess region is provided in the second dielectric layer to reveal a top surface of the first dielectric layer within the active array region. An angle between a sidewall of the second dielectric layer that defines the perimeter of the recess region and the top surface of the first dielectric layer is less than 90 degrees.

Abstract: The telescopic support device contains a number of tubular segments cascaded together by a number of intermediate segments. Each tubular segment has an outward bulge formed along a top aperture. A flat and rigid spacer is positioned in the bulge. Each intermediate segment has a cylindrical body with a C-shaped cross section and a socket besides a top aperture of the body. A curved plastic piece is positioned between the socket and the body of the intermediate segment. When each intermediate segment has its body threaded into a tubular segment, and another tubular segment is threaded into the intermediate segment, a bolt could be screwed through the socket, the bulge, and then against the spacer. The spacer in turn pushes the plastic piece so as to lock the inner tubular segment.

Abstract: A structure of a base drum counter-hoop mounted clamp is provided for attaching a small-sized music instrument to a counter hoop of a base drum. A clamp body is shaped to have upper and lower locking platforms that are substantially parallel and connected by a vertical plate, which has a side surface from which a pivot seat projects to pivotally couple a connection member. Opposite ends of the connection member are respectively coupled to a V-shaped clip body and a threaded bolt bar. With the threaded bolt bar being tightened and driven downward, the clip body is upward pushed against and secured to the counter hoop of the base drum. A holder formed atop the upper platform receives and fixes a support bar that supports an additional music instrument thereto.

Abstract: A snare drum stand lock adjustment comprised of two plates containing an inner channel to merely clamp a lever of a connector; both plates being pivoted to each other on one side with an axial pin; one end of the lock adjustment being fastened to a brace of the stand and the other end receiving insertion of a lever from a connector to permit easy and secure operation of the lock adjustment.
