Abstract: A server apparatus includes an analyzer unit which analyzes log-in information for a server received from a client, determines an authentication scheme of the server, and extracts, from the log-in information, provisional authentication information in a form representative of variable information. The analyzer unit stores, in the storage device, information representative of the authentication scheme and the provisional authentication information as the variable information. The analyzer unit also stores, in the storage device, as the variable information, authentication information of a user for the server that is associated with representative authentication information of the user.

Abstract: High-frequency signals from an oscillator (10) are transmitted, through a power divider (12) and a switch (14), from transmission antennas (T1, T2, T3). Reflection waves reflected by targets are received by reception antennas (R1, R2) to thereafter be fed via a switch (16) to a mixer (18). The mixer (18) is supplied with transmission high-frequency signals from the power divider (12) to retrieve beat-signal components therefrom, which in turn are converted into digital signals for the processing in a signal processing circuit 22. The transmission antennas (T1 to T3) and the reception antennas (R1, R2) are switched in sequence whereby it is possible to acquire signals equivalent to ones obtained in radars having a single transmission antenna and six reception antennas.

Abstract: A signal processing unit detects the azimuthal direction of a target in accordance with the phase difference between signals received by two receiving antennas. Then, by sequentially switching plural transmitting antennas having mutually different beam directions with a switching device, received signals are obtained using each of the transmitting antennas.

Abstract: A screw adapted for plasticizing a fiber-reinforced thermoplastic resin wherein screw lead (distance of the resin advancement in the direction of the axis per 1 revolution of the screw when it is postulated that the screw channel is 100% filled with the resin) of the screw in its compression section decreases in the direction toward the forward end of the screw. A plasticizing apparatus wherein such screw is mounted. A method for molding a fiber-reinforced thermoplastic resin by using such an apparatus. A molded article produced by such molding method. In the present invention, shear force of sufficient level can be obtained to avoid the formation of clumps while breakage of the reinforcing fibers is avoided to leave long fibers in the molded article. The resulting molded article has excellent mechanical properties, and such article is quite useful as a material for use in automobile parts and other parts.

Abstract: A MUSE sound decoder detects a broadcasting/non-broadcasting identification flag included in the control signals in an applied MUSE signal to determine whether the MUSE signal is broadcasted or non-broadcasted. The MUSE sound decoder further includes a frame synchronization protection circuit for protecting frame synchronization over a predetermined frame synchronization protection time period when the frame synchronization pattern is not detected at the proper timing. The frame synchronization protection circuit sets the frame synchronization protection time period to a long time period when the MUSE signal is determined to be a broadcasted MUSE signal, and to a short time period when the MUSE signal is determined to be a non-broadcasted MUSE signal. Appropriate muting of a sound signal can be carried out according to the condition of the received MUSE signal.

Abstract: A convertor for converting a sub-sample television signal such as MUSE signal, which is obtained from a high density television signal by way of offset sub-sampling the horizontal scan lines of the high density television signal and time compressing the transmission band, to a standard television signal includes odd field and even field vertical filters for filtering odd lines and even lines in the MUSE signal, and time base expanders for selecting predetermined lines from the lines filtered by the odd and even field vertical filters and for expanding on time base the selected predetermined lines. Also, another vertical filter is provided for processing the signal from the time base expanders according to the sub-sampling phase.

Abstract: A land vehicle navigation system is adapted to display the present position of a vehicle by receiving signals from a combination of satellites under the global positioning navigation system. The present position of the vehicle is displayed on a screen, superposed over map data. To obtain the best global positioning data, the combination of satellites is selected in connectio with the visibility. To perform the positive reception of signals from the satellites as the vehicle is running in an urban area, data relating to the building height around the area can be obtained from a geographical information section including data indicative of the map and the building height distribution with respect to the area to determine the visibility.

Abstract: A frame synchronizing signal detecting circuit detects a frame synchronizing signal in a video signal. When the frame synchronizing signal is not detected by the frame synchronizing signal detecting circuit, a clamp level switching circuit is responsive to a switching signal from a timer circuit for generating alternately an upper clamp potential V.sub.+ and a lower clamp potential V.sub.-. When the frame synchronizing signal is detected by the frame synchronizing signal detecting circuit, the clamp level switching circuit generates a normal clamp potential V.sub.0. A clamping pulse generating circuit is responsive to an output from the frame synchronizing signal detecting circuit for generating a clamping pulse. A clamping circuit is responsive to the clamping pulse for clamping an analogue video signal at the clamp potentials V.sub.0, V.sub.+ or V.sub.- from the clamp level switching circuit.
