Abstract: The present invention discloses an AC/DC converting control circuit, which is used in transformerless AC/DC converting apparatuses. The control circuit primarily includes a current-switch circuit, a duty-control circuit and a load-current limiting circuit. When electrically connecting with a load and a voltage source in series, the control circuit of the present invention reduces the oscillation during on/off switching and provides a stable output current.

Abstract: A cable antenna includes a circuit board to which first ends of two antenna cables and a coupling cable are soldered. A second end of the coupling cable forms a connector for connection with a signal receiving/transmitting circuit. Each of the antenna cables has a second free end exposed to the atmosphere for receiving/transmitting electromagnetic signals. An outer jacket of each antenna cable is removed along a first predetermined length measured from the free end thereof to expose a braided shield. A second predetermined length of the braided shield measured from the free end is removed for exposing an inner dielectric layer that surrounds a core conductor. The second length is less than the first length thereby leaving a portion of the exposed braided shield on the inner dielectric layer. The braided shield that is cut from the cable is twisted to form an elongate consolidated conductor.

Abstract: A diverter tub spout body includes a tubular main portion which has an annular flange extending radially inward from the first end thereof, and a second end which is an open end. The annular flange has a hole defined centrally therethrough and a hose connecting tube extends from the periphery defining the hole of the annular flange so as to be connected to the supply pipe. An outlet portion is connected to the first end of the tubular main portion and communicates with the hole of the annular flange. An aperture is defined through the wall of the tubular main portion and located below the annular flange so that bubbles release via the aperture when immersing the diverter tub spout body into the electroplating bath solution.

Abstract: A triple well structure for an embedded dynamic random access memory uses an ion implantation performed on a portion of the first conductive type substrate between a second conductive type source and a second conductive type deep well. A first conductive type block region is formed between the second conductive type source and the second conductive type deep well.

Abstract: A diverter tub spout body includes a longitudinal portion and a transverse portion extending from the longitudinal portion with a separate wall connected between the longitudinal portion and the transverse portion. A connecting tube extends from the separate wall, the interior of the transverse portion and the interior of the longitudinal portion communicates with each other via the connecting tube and a hole defined through the separate wall. An aperture is defined through the separate wall and located between the peripheral wall of the longitudinal portion so as to dispense bubbles when the diverter tub spout body is immersed into the electroplating bath solution.

Abstract: A carcass cremator has an inner chamber which is defined by firebrick walls. At least two thirds of the inner chamber is buried underground. A tube is disposed at the center of the inner chamber. A metal bowl is disposed on the tube. A top cover covers the top portion of the inner chamber. A flame inlet is formed at the lower portion of the firebrick walls. A vortex space is formed in the inner chamber. The flames enter into the vortex space via the flame inlet.
