Abstract: Described is a simple and inexpensive method of manufacturing a floor panel (2) with which a floor panel (2) can be produced with a beveled or recessed edge (10a, 10b, 25, 26), a top surface layer (4) extending continuously and in one piece from a top side (3a) of a core (3) over the beveled edge (10a, 10b, 25, 26). A panel body (12) is first of all provided with a core (3, 13), a top side (3a, 13a) of the core (3, 13) being provided with a top surface layer (4). A recess (15) is then formed from a side surface (13b) into the panel body (12), the recess extending under the top surface layer (4) and leaving a freestanding ledge (16) which includes the top surface layer (4). The recess (15) is then closed by fixing the first and second recess surfaces (15a, 15b) to one another.

Abstract: A phase detection circuit includes a phase frequency detector for comparing a first input signal and a second input signal and outputting a first phase comparison signal and a second phase comparison signal, and a sensing circuit for sensing a pulse width difference between the first phase comparison signal and the second phase comparison signal and outputting phase detection signals which have different logic values.

Abstract: A Schottky diode comprises an ohmic layer that can serve as a cathode and a metal layer that can serve as an anode, and a drift channel formed of semiconductor material that extends between the ohmic and metal layers. The drift channel includes a heavily doped region adjacent to the ohmic contact layer. The drift channel forms a Schottky barrier with the metal layer. A pinch-off mechanism is provided for pinching off the drift channel while the Schottky diode is reverse-biased. As a result, the level of saturation or leakage current between the metal layer and the ohmic contact layer under a reverse bias condition of the Schottky diode is reduced.

Abstract: The present invention relates to a method for providing flowers characterized in that they have the look and feel of fresh flowers. The method comprises a selection and cutting step, a step of setting up holder devices on grids, and three optionally repeatable dehydration, infiltration and evaporation steps. The present invention does not require the use of molecular sieves during the method. The method is also technically advanced and can therefore be implemented on an industrial scale.

Abstract: A memory structure that combines embedded flash memory and PPROM. The PPROM can be used as a memory structure. The flash memory can be used, e.g., as air replacement cells or back up memory, or additional memory cells. The PPROM cells are stacked on top of the flash memory cells and the PPROM density can be increased by implementing three-dimensional PPROM structures.

Abstract: A charge pump apparatus comprises a plurality of charge pump stages. The charge pump stages each include a respective output node. Output nodes are connected to charge boosting circuitry and to precharge circuitry. The charge boosting circuit receives one or more clock signals. The precharge circuits have a first state allowing the respective pump-stage output node to fluctuate at a level above a standby wordline voltage, and a second state coupling the respective pump-stage output node to the standby wordline voltage.

The first plug is movable along a first direction substantially parallel with the front surface for engaging with the buckle, and the release button is movable along a second direction substantially parallel with the front surface for pushing the first plug out of the buckle.

Abstract: A self-programmable control system for an electronic device is disclosed. The electronic device may comprise a ceiling fan and associated light fixtures, wherein the ceiling fan is manufactured to be coupled with an AC power source, and includes a motor with associated connection wires for rotating fan blades. Such ceiling fan system may further include at least one lower light fixture, and one upper light fixture, with associated connection wires for adjusting light intensity. The control system may utilize a plurality of wireless or hard-wired controllers, wherein each controller contains a transmitter configured to encode and transmit a control signal from the controller to a receiver. The control system further includes a receiver adapted to receive the encoded control signals, decode the instruction, and provide the decoded instruction to a component of the electronic device.

Abstract: A microphone which does not need a hanger plate structure is provided. A conductive hanger knob is provided at the back of the rear case of a microphone case. The hanger knob has three layers of a conductive shaft part, an insulator part and a conductive bolt part in the named order from its center. The shaft part is electrically insulated from the bolt part. A notch that locks the bolt part of the hanger knob at a hanger surface is formed at a conductive hanger hook on which the microphone is hooked via the hanger knob. A support spring portion disposed at the back of the hanger surface urges the shaft part of the hanger knob locked at the notch in a direction of pushing the shaft part back toward the hanger surface. This provides electric conduction between the shaft part and the bolt part via the hanger hook.

Abstract: A frequency adjusting apparatus includes a frequency control signal generating unit that generates a multi-bit frequency control signal, which is changed in level bit by bit, in response to a reference clock signal, and a frequency adjusting unit that adjusts the frequency of the reference clock signal in response to the multi-bit frequency control signal.

Abstract: A user location monitoring unit of a data communication control apparatus monitors a message sent from a wireless device via a repeater. Upon detection of a change in the location of the wireless device, the user location monitoring unit updates the location information in the database and notifies via the Internet a management server of the location change. Upon receipt of the message via the Internet, a destination address confirming and correcting unit of the data communication control apparatus uses the user ID of a destination wireless device as a search keyword to search the database. In turn, the destination address confirming and correcting unit corrects the destination address of the message to the latest address of the pertinent user ID and outputs the corrected message to a received message forwarding unit.
