摘要： An image forming device including a plurality of image forming units each for forming an image on an intermediate transfer body using one of different colored inks. Different colored images are selectively formed in an overlapping relation on the intermediate transfer body, thereby forming a multicolor image thereon. Each different colored image is formed by a thermal transfer operation in which ink on an ink holding member is heated, melted, and then transferred directly onto the intermediate transfer body or onto an existing ink image on the intermediate transfer body. Heat to be supplied to the ink to be transferred onto the existing ink image is insufficient to melt ink in the existing ink image.

摘要： Disclosed is a photo-pressure sensitive recording sheet developing apparatus in which vibratory pressure generated by an ultrasonic wave generating means is applied to a photo/pressure sensitive recording sheet using microcapsules carrying a latent image formed through exposure to thereby develop the photo/pressure sensitive recording sheet by the vibratory pressure. Preferably, the ultrasonic wave generating means is formed as a single resonance system and has parallel surfaces opposite to each other, each of the opposite surfaces having a vibration mode so that the opposite surfaces are displaced in the directions opposite to each other and substantially along a vertical axis of the opposite surfaces.

摘要： A test sheet is set in a droplet discharge device at a first distance. At least one droplet is discharged toward the test sheet from a nozzle formed in the droplet discharge device to form at least one first dot on the test sheet. The test sheet is set in the droplet discharge device at a second distance differing from the first distance. At least one droplet is discharged toward the test sheet from the nozzle to form at least one second dot on the test sheet. A nozzle position error or a nozzle discharge angle error are calculated from the position of the first dot, the position of the second dot, the first distance, and the second distance. Testing inkjet heads in this manner allows accurate testing for errors in nozzle position or discharge angle.

摘要： The invention relates to a method for setting a tolerance of each standard value, which is a factor in determination of ink droplets landing accuracy, to an ink jet printer that is set up using the method, by implementing a sensory test using printed results of an ink jet printer. With the tolerances set by the method, banding can be effectively obscured without significantly improving the mechanical precision of the ink jet printer. Particularly, when A1 is a deviation of a sheet feeding amount in the sub-scanning direction obtained by a dot line length of an average value of the sheet feeding amount in the sub-scanning direction from an ideal value, B1 is a maximum value of a deviation in the sub-scanning direction between the same color dots, and C1 is a maximum value of a deviation in the main scanning direction between the same color dots, it is set such that a value of tolerances of A1, B1, and C1 is A1≦B1≦C1.

摘要： In the piezoelectric transducer, the elastic member vibrates, being excited by the first electromechanical transducing element. The impedance element on the second electromechanical transducing element is adjusted so that the vibration frequency and the resonance frequency of the elastic member should be almost the same. In the ultrasonic motor using the piezoelectric transducer, the vibration having the same frequency as that of the vibration of the elastic member is applied to the elastic member. This applied vibration has a direction differnt from that of the viration of the elastic member. The applied vibration and the vibration of the elastic member form approximate elliptical vibration, thereby rotating the rotor. The piezoelectric transducer of variable structure can control the resonance frequency in a wide range without electric power. The piezoelectric transducer can efficiently transduce applied electricity into approximate elliptical vibration of the elastic member, thereby generating great mechanical drive power. The electromechanical transducing element and the impedance element can compose a simple and compact vibration control unit. Since the electromechanical transcuding element and the impedance element form a closed circuit consuming no electric power, no power source circuit is required. The vibration control unit adjusts the resonance characteristic of the closed circuit, thus quantitatively controlling the frequency distribution and the amplitude of the mechanical vibration.

摘要： It is possible to minimize the amplitude of residual vibration of a piezoelectric actuator so as to maintain the image quality of a formed image at a preferable level in case of an ink jet head, for example. A liquid discharge device includes a control unit (14) for ON/OFF control of a drive voltage applied to the piezoelectric actuator. The control unit (14) has a micro vibration control section (23) for drive-controlling a drive circuit so as to micro-vibrate the piezoelectric actuator in a waiting state not discharging a liquid drop from a nozzle, in a range that no liquid drop is discharged in the nozzle. The piezoelectric ink jet head includes the liquid discharge device. The drive method is for micro-vibrating the piezoelectric actuator in the waiting state not discharging a liquid drop from the nozzle, in a range that no liquid drop is discharged from the nozzle.

摘要： A printer is provided with an ink jet head and a controller. The ink jet head prints on a print medium by discharging ink. The ink jet head comprises a plurality of units. Each unit comprises a nozzle for discharging ink, a pressure chamber communicating with the nozzle, and a piezoelectric element facing the pressure chamber. The piezoelectric elements form at least two element lines. Each element line is formed by at least two piezoelectric elements aligned in a first direction. Each element line is aligned in a sec direction which is different from the first direction. The controller controls the ink jet head to print on the print medium by changing voltage applied to each piezoelectric element of the ink jet head. The controller controls timings at which the controller changes voltage applied to each piezoelectric element by the element line. It is preferred that a timing at which the controller changes voltage applied to one of the two adjacent element lines is different from a timing at which the controller changes voltage applied to the other of the two adjacent element lines.
