Abstract: The wiper system with translational motion is additionally capable of moving the wiper arm in angular motion at an auto stop position so that the wiper blade may be stowed away from the view of the vehicle operator when the wiper system is not in use. The retracted position may be defined immediately below the lower edge of the windshield. When a mist switch is turned on so as to effect a quick wiping action, the wiper arm can angularly move from the retracted position to the upright position. When the wiper arm is already in the translational motion, turning on of the mist switch may increase the speed of the translational motion. To prevent the wiper blade from obstructing the view of the vehicle operator in an intermittent mode, the position of the temporary stop of the wiper blade may be selected at the reversing position which is remote from the vehicle operator.

Abstract: A digital television broadcast receiver comprising a digital signal demodulator, wherein the frequency of an intermediate frequency signal is made higher than the maximum frequency of any received signal, the intermediate frequency signal being demodulated by the digital signal demodulator, whereby interference attributable to a carrier signal from an oscillator of the demodulator is suppressed during demodulation.

Abstract: In a washer nozzle assembly, the upper lip portion defining a nozzle opening extends more forwardly than the lower lip portion so that the part of the washer liquid directed upward is blocked by the longer upper lip portion, and the upper part of the spray pattern includes more liquid droplets of larger sizes as compared to the prior art. Thus, the loss of washer liquid by being flown above the windshield at high speed can be reduced, and the spray pattern of the washer nozzle assembly can be optimized for all speeds.

The inventive tuner comprises a first frequency conversion stage for converting in frequency a channel-select received signal to a first intermediate frequency signal to be output, a second frequency conversion stage for converting in frequency the first intermediate frequency signal to a second intermediate frequency signal to be output, and an analog and a digital demodulator for demodulating the second intermediate frequency signal.

Abstract: A rugged shaped sheet capable of exhibiting improved non-slip properties and aesthetic properties and a process for manufacturing the same. The rugged shaped sheet includes a base sheet member and a rugged pattern of a predetermined shape adhered to the base sheet member. The rugged pattern is formed of a plurality of pattern elements different in size, configuration and/or properties into a multi-layer structure. The rugged shaped sheet is manufactured by pouring an elastomer liquid material into each of perforated plates, semicuring the elastomer and laminating the perforated plates on each other, resulting in forming the rugged pattern of a predetermined shape on the base sheet member.

Abstract: A communication system testing method for testing a communication unit including a communication line and components of a communication unit such as a terminal unit. In addition, a control apparatus includes pause control means and control means, both of which are incorporated in an integrated communication control circuit. When the integrated communication control circuit is in the pause state, the pause control means outputs a pause permission indicating signal and detecting signal. The control means discontinues the supply of the main-clock signal by outputting the detecting signal, thereby limiting energy consumption.

Abstract: The invention provides a filter circuit for use in a double-conversion TV tuner exhibiting low diode insertion loss, in which intermodulation distortion does not occur even when an incoming signal has a large amplitude. In the filter circuit according to one preferred embodiment of the invention, there are provided three bandpass filters (BPFs) which allow corresponding RF signals in different frequency bands to pass through them, and six variable attenuation diodes whose impedance is controlled by an AGC voltage applied to an AGC terminal (16). There are also provided switching diodes (20) disposed between an input terminal (1) and the inputs of three BPFs so that the switching diodes (20) select exclusively one of three BPFs so as to apply an RF signal received at the input terminal (1) only to the selected BPF (it will be assumed hereinbelow that the BPF (21) is selected).

The disclosed device includes first telephone number memory for storing a telephone number of a remote communication node when the data transfer device originates a communication session; second telephone number memory for storing a telephone number of the remote communication node when the remote communication node originates the communication session; start command generating circuit for generating a start command; and data transfer circuit for transferring data.

Abstract: In a digital network system, such as ISDN (Integrated Service Digital Network) system, a data link is established between transmit-side and receive-side stations so that a data transfer is performed onto a public telephone line in accordance with a predetermined protocol. The transmit-side station compresses data read from a storage medium and then transfers compressed data to the receive-side station, while the receive-side station expands the compressed data and then writes it into a storage medium. Before transferring the compressed data, the transmit-side station transmits a data transfer request to the receive-side station, so that if the receive-side station is now ready to receive the compressed data, the transmit-side station transfers the compressed data to the receive-side station.

Abstract: Communication-control equipment having data-processor, primary storage for storing process data of the data-processor, secondary storage for storing DMA data as well as the process data, and DMA bus for transferring only the DMA data communicated between the secondary storage and a transmission or receiving buffer. The data-processor can communicate with the primary storage during DMA data transfer, because the DMA data are transferred through the DMA bus and so the address bus and data bus connecting data-processor and the primary storage are available during the DMA transfer.

Abstract: A data transmitting equipment transmitting data between a desired remote equipment connected via communication line, comprising password setting means, communication control means and status display means. The password set by a user is stored in the password setting means. Transmission control means compare said password with a set password in a remote equipment, allow said data transmitting of said data if both passwords are consistent, delete said set password when said transmitting ended. If the password of the password setting means is not deleted, status display means show that said password remains in the password setting means. According to the above mentioned present invention the password is automatically deleted after the end of the data transmission, and moreover the set password is never displayed during or after use. Accordingly, an exposure of the password to a third party is prevented.
