Abstract: A liquid ejecting apparatus includes a first nozzle, a second nozzle, an image formation control unit, a latent image formation control unit, and a position detection unit. The first nozzle ejects a first liquid droplet for forming an image on a recording medium. The second nozzle ejects a second liquid droplet that is transparent to visible light for forming a latent image on the recording medium. The image formation control unit, during the relative movement, ejects the first liquid droplet onto the recording medium to thereby form an image pattern. The latent image formation control unit ejects the second liquid droplet onto the recording medium so as to overlap the image pattern to thereby form a latent image pattern. The position detection unit recognizes the latent image pattern as a reference position on the recording medium and detects a relative position between the recording medium and the first nozzle.

Abstract: The electromagnetic clutch comprises a rotor connected to a drive source, an inner hub connected to a device that follows, an outer plate provided on the outside of the inner hub so as to enclose it, an armature coupled to the outer plate and opposing the rotor, an elastic member provided between the inner hub and the outer plate and adhered thereto, and an electromagnetic coil for, when magnetized, attracting the armature together with the outer plate to make them come into contact with the rotor, and when demagnetized, separating the outer plate and the armature from the rotor. Because of the configuration in which the armature and the outer plate are coupled in a heat-transmissible manner, a part of elastic member is formed so that heat is transmitted from at least a part of the armature to the part of the elastic member as if they are one piece.

Abstract: An electromagnetic clutch 1 has a construction in which an armature 5 and a plate 7 sandwich an elastic member 9 between them. A spring portion 7d is formed in the plate 7 and an elastic member 9a is so disposed as to cover a front side of the spring portion 7d, too. Elastic members 9b, 9c and 9d are disposed in a thin film form on an inner surface of elongated holes 5a of the armature 5 and the innermost and outermost diameter portions 5b and 5c of the armature 5. The distal end of each elastic member 9b, 9c and 9d is extended to the same plane as an end face 5d of the armature 5 on the rear side or to a position somewhat protruding from the end face on the rear side.

Abstract: In the disclosed electromagnetic clutch, a bent porion (15a) of a plate (15) comes into contact with an armature (6) attempting to move beyond a predetermined movable range, thereby restricting the movement of the armature (6). As a result, if an elastic member (14) is fused, a trouble is prevented which otherwise might be caused by the movement of the now-unsupported armature (6) beyond a predetermined movable range.

Abstract: While performing main scanning in which a head having a plurality of nozzles that eject ink is moved in prescribed forward and reverse main scanning directions relative to a print medium, print images are printed on the print medium by forming dots in each pixel aligned in the main scanning direction in accordance with print data. The dot formation position misalignment amount for each nozzle is corrected using image pixel value data indicating the existence of image pixels comprising images and adjustment pixel value data indicating the existence of adjustment pixels in which dots are not formed.

Abstract: The technique is provided that reduces degraded quality in printed results due to nozzles employed to record dots on each pixel in combination with the order in which these dots are recorded on pixels. A plurality of nozzles on a print head are grouped, in order from the nozzles that first reach a point over the print medium, into a first nozzle group, a second nozzle group, and a third nozzle group. During main scanning, certain pixels in main scan lines positioned facing the nozzles of the first nozzle group are targeted for dot recording. All pixels contained in main scan lines positioned facing the nozzles of the second nozzle group are targeted for dot recording. Those pixels among the pixels contained in main scan lines positioned facing the nozzles of the third nozzle group, and that have not previously had dots recorded thereon by the first nozzle group in a previous main scan, are targeted for dot recording.
