Abstract: PURPOSE:To enable uniform printing density even at the onset or printing operation and also printing at high speed by keeping a head temperature at a constant level through the output of a printing pulse to a printing head by control means during a low temperature period. CONSTITUTION:If a power supply for a printer is turned on, a printing unit is actuated, determining whether or not printing should be carried out. Should no printing be put into practice, the printer proceeds on to step 10 to determine whether or not the temperature is at low level. If it is not at low level, the printer returns to step 9, and if it is , the printer advances to step 11 to determine whether or not the head is in home position. If it is in home position, the printer moves to step 12 where a printing pulse is outputted to such an extent as not to cause thermosensitized paper to form a color for a certain period time. If the printing pulse is outputted for a certain period, the printer returns to step 9 and means such as motor drive, head drive, head position sensing and timing sensing are controlled by a control means for printing.

Abstract: PURPOSE:To correct the misalignment by a simple constitution and at a low cost by setting the ratio of a fundamental frequency which depends on an average angular velocity of a photosensitive body to a rotary fluctuation frequency component of the photosensitive body to an integer. CONSTITUTION:A photosensitive body 1 and a transfer drum 5 rotate in the direction as indicated with an arrow, respectively and an image developed on the photosensitive body 1 is transferred to paper 18 by a transfer device 8. An angle obtained by measuring an angle AOB made by an image forming point 21(A) and a transfer point 22(B) on the photosensitive body 1 against the center 20(0) of the photosensitive body 1, along the rotating direction of the photosensitive body 1 from the image forming point 21(A) is denoted as theta1. In a rotary fluctuation component of this photosensitive body 1, a main vibration frequency component is denoted as f1. However large finite amount the misalignment amount of the photosensitive body 1 caused by a rotary angular velocity fluctuation of the photosensitive body 1 may be, it does not become a misalignment on a print sample, when f1/f0 is an integer. In such a way, the image forming position can be adjusted without using a motor of high accuracy.

Abstract: PURPOSE:To enable pressing of a head to be released at an arbitrary position and enable inexpensive high-speed printing, by releasing the pressing of the head by initial rotation of a head-feeding drive source when the feeding direction of the head is changed. CONSTITUTION:With the first gear 30 first rotated clockwise by the drive source, the third gear 33 also is started rotating in the same direction, and when a pin 38 oscillates an arm 35, a T-shaped arm 31 is turned clockwise with the axis of the gear 30 as a center, and the second gear 32 is disengaged from the third gear 33. A cam plate 10 which a cam follower follows is provided on the axis of the third gear 33, whereby the pressing of the head is released at the time of the above operation. When the drive source is rotated in the opposite direction, the arm 31 rides over a hook part 35a provided at the tip of the arm 35 to turn the cam plate 10 in the reverse direction, thereby moving the head in a pressing direction. Accordingly, the pressing of the head can be released simply by the drive source, and printing speed can be enhanced.

Filed: 1998-05-30
Abstract: PROBLEM TO BE SOLVED: To improve responsiveness of initial ignition-advance control and insure the sure ignition-advance operation of a camshaft by operating ignition- advance of an oil control valve to a degree causing no trouble in operation to previously raise oil pressure in a hydraulic route on the ignition-advance side, before specified control condition is realized, when the camshaft is operated on the ignition-advance side. SOLUTION: When a program is started, an ECU judges whether an ordinary valve timing control condition is realized or not, in the case of YES, at warm-up restarting an internal combustion engine 2, an oil control valve 106 is operated by an ordinary valve timing control condition due to required ignition-lag to be a first ignition-lag. Meanwhile, in the case of NO, it judges whether a preceding step valve timing control condition is realized or not, and in the case of YES, the oil control valve 106 is operated into a second ignition-advance. Because the second ignition-advance is set to be a smaller value than the target ignition-advance of a first ignition-advance, oil pressure of an oil pressure route on the ignition-advance side 138 is raised by a hydraulic actuator 136, and responsiveness of intial ignition-advance control is improved.
