  • Patent number: 8613192
    Abstract: An engine exhaust gas purifier includes a filter, a hydraulic load mechanism, a clog detector and a forced actuation valve. The filter purifies the exhaust gas of the engine. The hydraulic load mechanism is driven by the engine's power. The clog detector detects a clogging state of the filter. The forced actuation valve forcibly increases an actuation amount of the hydraulic load mechanism. The filter is regenerated by increasing an engine load while maintaining an engine rotating speed, by increasing the actuation amount of the hydraulic load mechanism with an actuation of the forced actuation valve on the basis of detection information of the clog detector.

  • Publication number: 20130308924
    Abstract: An audiovisual data transmission system includes the following components. A filesystem module creates a file that contains at least one of video data and audio data stored in a storage unit. A conversion processing unit manages a file created by the filesystem module. A filesystem-in-userspace module provides an interface between the conversion processing unit and the filesystem module. An update detecting unit detects an update of at least one of video data and audio data contained in a file. In response to an instruction to acquire a file managed by the conversion processing unit received in a state where an update of the file is detected by the update detecting unit, a server makes an inquiry to the conversion processing unit and repeatedly performs a read process in which the file is read, via the filesystem-in-userspace module.

    Abstract: A multilayer bandpass filter includes a first capacitor electrode of a first stage LC parallel resonator, a second capacitor electrode of a second stage LC parallel resonator, and a third capacitor electrode of a third stage LC parallel resonator. Via electrodes and a line electrode define an inductor electrode of the first stage LC parallel resonator. Via electrodes and a line electrode define an inductor electrode of the second stage LC parallel resonator. Via electrodes and a line electrode define an inductor electrode of the third stage LC parallel resonator. The inductor electrodes of the three LC parallel resonators are arranged so loop planes thereof are disposed about a center axis extending in a stacking direction of dielectric layers. This permits setting of electromagnetic coupling between the LC parallel resonators of an input and an output stage, and allows a filter's attenuation characteristics to be freely set.
