Abstract: Disclosed is a burglar sensor arrangement structure for arranging, with respect to a vehicle interior member (10), a burglar sensor configured to detect an intrusion into a vehicle interior. The burglar sensor arrangement structure comprises an ultrasonic wave generation unit (2) for generating an ultrasonic wave, and a throat portion (18) for radiating the ultrasonic wave generated in the ultrasonic wave generation unit, from a outside opening (18a) thereof into the vehicle interior, wherein the vehicle interior member is formed with a groove (20), and the outside opening of the throat portion is opened at a bottom surface of the groove.

Abstract: Disclosed is an electronic key system which comprises a vehicle-mounted device and a plurality of electronic keys, and is configured to have: a normal mode in which a given processing is permitted to be executed by the vehicle-mounted device when a given wireless communication processing between the vehicle-mounted device and any one of the plurality of electronic keys is successfully completed; and a deactivated mode in which the given processing is inhibited from being executed by the vehicle-mounted device. The vehicle-mounted device is configured not to execute, in the deactivated mode, the given processing even when receiving an RF signal after transmitting an LF signal, during the given wireless communication processing, and the one electronic key is configured not to transmit, in the deactivated mode, the RF signal even when receiving the LF signal, during the given wireless communication processing.

Abstract: A process for dewatering sludges, which comprises performing a first stage agitation of the sludge to be dewatered during addition of a first high molecular weight flocculant developing in an aqueous solution an electric charge in polarity opposite to that of the sludge to effect neutralization of the electric charge of the sludge, conducting subsequently a second stage agitation of the sludge during a further addition of a second high molecular weight flocculant developing in an aqueous solution an electric charge in polarity opposite to that of said first flocculant to cause flocculation of the sludge and subjecting the so flocculated sludge to a dewatering operation, wherein a flocculant composed of a natural high molecular organic compound or a derivative thereof is used for at least one of said first and second flocculants with simultaneous employment of high power agitation for said first stage agitation, which process obtain a dewatered cake having low moisture content with efficient dewatering of the
