Abstract: A delay-locked loop for outputting a precisely signal relative to an input reference signal includes a plurality of selectively controlled delay elements and a delay element control circuit, including a phase detector for detecting a phase shift between the input reference signal and the delayed output signal and producing an error signal. Each of the delay elements includes a first input associated with a negative output and a second input associated with a positive output, whereby the positive and negative outputs are selectively coupled to a constant voltage source responsive to a first bias voltage and to a ground. The positive and negative outputs are responsive to a second bias voltage and the first and second voltage inputs. The constant voltage source and the positive output are coupled via a first transistor and the constant voltage source and negative output are coupled via being a second transistor.
Abstract: A four-way reversing valve includes a valve casing having a plurality of ports through which fluid flows, a valve main body fixedly installed to the valve casing and having a valve chamber in which a plurality of main port connection holes for selectively connecting the ports are formed, a main spool rotatably installed at the valve chamber of the valve main body, for selectively connecting the ports according to a rotation position, and a spool driving unit for reversibly rotating the main spool by using part of fluid supplied through one of the ports in the valve casing. Thus, the number of welding points is minimized by incorporating the overall pilot valves and excluding additional capillary connection for the pilot valves. Also, manufacturing thereof is made easy and, during the manufacturing and use thereof, the rate of breakdown due to defective welding can be remarkably reduced.

Abstract: A wooden beam (1) has several sections which are subjected to a transversal tension and which affect in particular the areas in which there are recesses or openings (3). Rod-shaped elements are provided in the form of screws (4) which are introduced in such a way that they extend crosswise to the longitudinal direction of the beam (1) in order to absorb this transversal tension. These screws are screwed in from the top side (5) or the underside (6) of the beam (1) and each extend over part of the height (H) of the beam (1) only and are therefore directly associated with the area (2) that is subjected to transversal tension.
Abstract: The invention relates to a detector for scattered light, especially for detecting particles in a carrier medium. Said detector comprises a housing (1) and an inlet (3) and an outlet (5) in the housing (1). The carrier medium flows through the housing between said inlet and outlet and on a flow path (7). The inventive detector also comprises a light source (9) that directs light to a scattered light centre (11) which lies on the flow path (7). The inventive detector further comprises a receiver (13) for a portion of the light which is scattered onto particles in the scattered light centre (15) and a light trap (15) for light which is not scattered in the scattered light centre (11). The aim of the invention is to improve such a detector for scattered light in such a way that compact construction and high responsiveness are guaranteed. The light trap (15) can be embodied in two ways.
Abstract: A plurality of transmitted data signals are received at a receiver. The receiver measures a channel response associated with the transmitted data signals. A system response is determined. The system response is expanded to be piecewise orthogonal. The received data signals data is retrieved based on in part the expanded system response.
Abstract: A spread spectrum system having an assignor, a spread-spectrum processor and a transmitter. The assignor assigns each arriving information signal to a message-code signal. Each message-code signal is different then other message-code signals. The spread-spectrum processor generates a pilot code signal and processes the information signals with the message-code signals to generate spread-spectrum process-message signals synchronized to the pilot-code signal. A transmitter combines the spread-spectrum process-message signals and the pilot-code signal to generate a CDM signal. The transmitter modulates the CDM signal with a carrier signal for transmission over the communications channel.

Abstract: A measuring gas pump (1) including a pump housing (2) with a pump chamber (3) inside which is sealed by a working membrane (5). The membrane (5) is connected: by a connecting rod (8) or a similar type of lifting device to a crank mechanism (9). A heating device is provided in the upper area of the pump housing, specifically in the pump head (10). On one hand, in the drive-transmission area between the head of the connecting rod (6) on the membrane side and the crank mechanism (9), there are holes (11) for the reduction of heat transfer to the crank mechanism which are spaced in a longitudinal direction of the connecting rod and which are also diametrically opposed, in peripheral direction, with a resulting reduction in heat conductivity. On the other hand, there is an enlargement of the surface area, at least in the area adjacent to the crank mechanism, for purposes of heat dissipation, specifically through cooling ribs (12).
Abstract: A rotary piston displacement device having an impeller housng with an approximately cylindrical receiving chamber in which an approximately cylindrical piston, which has a smaller outside diameter than and which is mounted eccentrically relative to, the receiving chamber, is provided mounted on an eccentric drive. The rotary piston forms an approximately sickle-shaped interspace between its outer wall and the inner wall of the receiving chamber. This interspace is divided into a pressure chamber and a suction chamber by a separating crosspiece that is placed between an inlet opening that is located inside the housing and an outlet opening. The outer and inner fixing locations of the separating crosspiece, which is connected to the housing on the one side and the piston on the other side, are offset with respect to one another in the peripheral direction of the rotary piston.

Abstract: A system and method for establishing initial synchronization for the link between a UE and a base station in a communication network uses window exclusion logic in order to avoid a deadlock condition upon a detection of the wrong public land mobile network (PLMN). The communication signal is processed in a three step decision process. The first decision step determines a chip offset of the strongest path detected over a frame of samples. In response to the first decision, the second step generates a scrambling code group number and slot offset for retrieving the secondary synchronization code. The third decision step retrieves a primary scrambling code in response to the code group number for synchronizing the UE to the base station.
