Abstract: PURPOSE:To easily constitute an optical system and to attain the reception of high sensitivity by providing at least two light receiving devices and monitoring a polarizing condition in an electric signal step. CONSTITUTION:A signal light is given through a polarization operating device 20 to a mixing circuit 21 and a local oscillating light is outputted from an optical local oscillating circuit 22 and given to the mixing circuit 21.

IPC: G08B17/00
Filed: 1994-10-27
Abstract: PURPOSE: To provide a tester for a disaster prevention sensor which can secure the safety for a test worker of a sensor and also can extremely reduce time for testing. CONSTITUTION: A receiver 1 successively calls out the analog disaster prevention sensors 4 through a signal line 3 to make them return each sense data and then to decide whether these sensors 4 are normal or not and also transmits the sense data as they are through an external input/output terminal 5.

Abstract: PURPOSE:To obtain a book manuscript reader capable of holding a book manuscript so that an image can be stably read at a high speed by setting two orthogonal surfaces of guide rails arranged opposedly in parallel in a subscanning direction as the reference surfaces in the up-and-down direction and the main scanning direction of a read unit. CONSTITUTION:The two orthogonal surfaces of the L-shaped guide rails 60a and 60b arranged opposedly in parallel in the subscanning direction of a scanning unit 15 are set as the reference in the up-and-down direction and the main scanning direction of the unit 15, and a fixed roller 61 attached to the unit 15 is brought into elastically press-contact with the guide rails 60a and 60b. Since the unit 15 moves to scan in a state where the lower surfaces of the guide rails 60a and 60b are set as the positioning reference in the up-and-down direction of the unit 15, the unit 15 is prevented from being pushed up by pressuring force even when the pressuring force from below acts on the unit 15 by the surface of the book document because of the ascent of an elevating base, and stable reading scanning is performed.

Abstract: PURPOSE:To realize multicolor output low in running cost by constituting an ink retainer of a plurality of kinds of temperature-sensitive liquid absorptive resin differnt in transition temperature and absorbing ink having different color in the prescribed place of the temperature-sensitive liquid absorptive resin. CONSTITUTION:An ink retainer 1 is constituted by laminating temperature- sensitive liquid absorptive resin different in transition temperature on a base film and providing the layer of the resin in the outside. The ink retainer 1 is wound in a stretching state between a transfer part A and an ink supply part B. In the ink supply part B, a part of the ink retainer 1 is immersed in ink 8d, 8c, 8b held in the ink feeders 7d, 7c, 7b by guide rolls 3b, 3d, 3f. The melting temperature of each ink is set lower than the transition temperature of the corresponding each temperature-sensitive liquid absorptive resin. While the ink retainer 1 is passed through each ink, each ink is absorbed into each resin. In the transfer part A, a thermal head 2 is opposed to a platen 5 through a recording medium 6 and the ink retainer 1. Ink having desired color is drained by setting the heating temperature of the thermal head 2 and multicolor printing is enabled.
