Abstract: A switching arrangement for activating a plurality of electrical devices connected to a communication line. The switching arrangement monitors the communication line for the reception of activation signals, and also transmits activation signals to the communication line. The switching arrangement activates an electrical device (from the plurality of electrical devices) connected to the communication line, in response to the detection of the an activation signal, to shift the electrical device from a dormant state (in which electrical consumption by the electrical device is minimized) to a normal, functional operational state (in which a maximum electrical consumption of the electrical device occurs) only when the electrical device is actually being operated. By switching the electrical device between a dormant state and an operational state, the amount of electrical power required to operate the plurality of electrical devices is reduced.

A deflector has first and second liquid prisms disposed with a movable transparent plate therebetween, and a controller changes vertex angles of the respective prisms by inclining the movable transparent plate in order to correct for a displacement of the image on the imaging surface.

Abstract: An optical scanning device emits a scanning laser beam which scans a photoconductive material, and a detection device located upstream with respect to the scanning direction of the laser beam. The laser beam is first emitted to scan the detection device, and the reception of the laser beam is detected by the detection device. The emission of the laser beam is terminated as soon as the detection device first detects the reception of the laser beam. A scanning laser beam modulated with image information is then emitted to scan the photoconductive material.

Abstract: Temperature indicator for refrigerated products operating on the principal of solidification and melting of liquid bodies at room temperature is provided with a transparent envelope containing a capsule filled with an aqueous solution which is liquid at room temperature.
