摘要： PROBLEM TO BE SOLVED: To improve productivity by shortening a cleaning time. SOLUTION: An ink fountain roller 15 is reciprocated between an ink duct roller 10 for forming an ink duct 9 and a mixing roller 16 for forming an ink transfer roller group 18. Cleaning liquid 24 is supplied to a roller 17 at an upstream side of the roller group 18, and an ink blade 21 for scraping together the ink is brought into contact with a swing roller 3 at a downstream side. A transfer roller 19 for transferring an ink roller 13 continuously to the roller 16 is provided simultaneously oppositely to the rollers 10, 15. The roller 10 is also rotated to an opposite direction (clockwise direction in the drawing) to that at the time of printing.

摘要： PROBLEM TO BE SOLVED: To shorten a cleaning time and to prevent a failure in cleaning. SOLUTION: An ink device 3 is formed of the ink roller such as form rollers 12 which freely detachably come into contact with a plate cylinder 2, swining rollers 11 and a milling roller 15. The form rollers 12 are separated from the plate cylinder 2 and rotated. Cleaning liquid 26 poured to rollers 15, 16 through a spray pipe 25 is transferred to clean the respective rollers of the ink device 3. Waste liquid of ink is collected in a cleaning liquid tank 20 by a blade 21 which is freely touched and separated to/from the circumferential face of the swinging roll 11 by actuation of an air cylinder 24. A first brightness detection sensor 28 for detecting brightness of the milling roller 15 on the upstream side and a second brightness detection sensor 29 for detecting brightness of the swining roller 11 on the downstream side are provided. When the detection value of both brightness detection sensors 28, 29 reaches the setting value, the air cylinder 24 is actuated and the blade 21 is separated from the swining roller 11 and cleaning work is finished.

摘要： PROBLEM TO BE SOLVED: To provide an advantageous structure for realizing a single-chip structure as a whole. SOLUTION: For example, the current of a light-emitting command signal generating section 22 in a pulse-width modulation/intensity-modulated signal generating section 11 is a monitor current of a light-receiving element 2 in terms of a direct current, and therefore, is not affected by changes in the temperature inside of an integrated circuit 20. Thus, by providing an external element for setting the current value of the light-emitting command signal generating section 22 and adjusting this external element, the monitor current may be stabilized, so that a desired optical output may be provided in accordance with the characteristics of a semiconductor laser 1 and the light-receiving element 2, and overall integration may be realized without troubles.

SOLUTION: A pulse width modulation-intensity modulation signal generating section 22 generates light emission command signals, an error amplification section 23 constitutes an optical-electrical negative feedback loop 3 together with a photodetector 2 to control the current of a semiconductor laser 1, so as to make the detected signals of the photodetector 2 equal to light emission command signals. Moreover, a current drive section 24 outputs a drive current, which is generated by the sum of or a difference between the control current of the optical-electrical negative feedback loop 3 and the operating current of the drive section 24, as a forward current to the semiconductor laser 1. An integrated circuit 20 contained in a single bipolar transistor chip is composed of the pulse width modulation-intensity modulation signal generating section 11, the error amplification section 23, and the current drive section 24, and the current drive section 24 is provided inside the optical-electrical negative feedback loop 3.

摘要： PROBLEM TO BE SOLVED: To improve the fatigue characteristics of a steel work by conducting shot peening treatment of the surface of the steel work with fine metal grain in a specific condition. SOLUTION: A shot peening treatment to project fine hard metal grain of 20 to 100μm grain size in the high velocity >=80m/sec making air or the other gas as a carrier is executed onto a valve spring of an engine or a coil spring of a clutch spring, etc., requiring the fatigue characteristics. In this case, the shot peening condition is regulated so that the surface temperature of untreated spring material is set between >=150 deg.C at which the cementite solubility is raised higher than at the room temperature and the temperature at which the restore recrystallization of steel and austenitizing are caused. Or by executing two step shot peeing treatment in advance of this shot peeing treatment, the shot grain of 100μm to 1.0mm is projected and the compression residual stress is added at the position of 0.05mm to 0.5mm depth from the work surface, thus the fatigue characteristics of the steel work is improved further effectively and largely.
