Title: Expander apparatus for plastic film
Inventor: HARA SHIYOUJI
IPC: B29D7/01
Filed: 1983-05-16
Abstract: PURPOSE:To make it possible to smooth creases of a plastic film using a low tension without causing damage to the plastic film, by forming a groove for supplying compressed air in the minor arc side of an arcuate and cylindrical expander of a porous material, and providing the opposite sides of the expander respectively with rotatable rolls that have the same diameter as that of the expander. CONSTITUTION:The surfaces of porous rolls 6, 6' are under the influence of a sucking force via air sucking holes 8, 8' by a vacuum pump. As a result, the opposite sides of a wide plastic film 2 are held by the sucking force. With this state kept when compressed air is fed via a groove 4 from an attachment 9 to a porous expander 3, the plastic film 2 is inflated, and the creases of the plastic film 2 is smoothed with the plastic film 2 floated. Since the feeding of the plastic film is effected by the rotatable porous rolls 6, 6', the tension exerted to the plastic film 2 is less.

Title: Typeprinter
Inventor: YANAGIURA TAKASHI
IPC: G06K15/06
Filed: 1980-06-24
Abstract: PURPOSE: To enable the automatical recognition on the set position and the width of a blank sheet, by storing position information on a loaded blank sheet in a memory, and considering a typeprinting operation onto the blank sheet on the basis of the stored information.  
     CONSTITUTION: A multiprograming unit MPU further shifts a carriage rightwards by one character (one column) and adds +1 to a register R1, to recognize the width of a loaded blank sheet. After multiprograming unit MPU raises the content of the register R1 by +1, the multiprograming unit MPU recoginizes the existence or absence of the blank sheet through an interface PiAa. If there is the blank sheet, the multiprograming unit MPU shifts the carriage by one character, and controls to add +1 to the register R1. Thus, the existence or absence of the blank sheet is recognized, whenever the carriage is shifted by every one character. When the blank sheet is used up, the multiprograming unit MPU stores a value, which is produced by subtracting the value of a register R2 from the value of the register R1, into a register R3, and completes the judgment and control of the blank sheet- loading.

Title: Gear type power transmission device in image forming device
Inventor: KATO HIROYUKI
IPC: B65H5/06
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To arrange a simple-structure and compact rotating direction switching means in the gear type power transmission mechanism in an image forming device. SOLUTION: A paper supply roller is driven through a first gear group 29 by one driving motor which can be normally and reversely rotated. A resist roller is driven by a second gear group. In the group 29, the respective large- diameter gears 42 and 42 of a first set of clutch gear pairs 39 and a second set of clutch gear pairs 40 where coil spring clutches 44 are wound round so that the loosening directions thereof mutually become reverse are arranged in parallel with an intermediate gear 37. Since the tightening action and the loosening action of the clutches 44 of two sets of gear pairs 39 and 40 mutually become reverse when the rotating direction of the driving motor is switched, the idle section of power transmission is hardly caused. Thus, the paper supply roller can be rotated in a fixed direction though the rotating direction of the driving motor is switched.

Filed: 1985-04-22
Abstract: PURPOSE:To obtain required edge shape by reciprocal movement reversing at randomly arranged reversal points according to a fundamental traverse pattern based on an edge shape of a cross-wound yarn cone. CONSTITUTION:A cross-wound cone is formed by rotating a yarn winding bobbin 2 contacted by a friction roller 1 while making a traverse guide 3 perform traverse movement by means of a servomotor 5. Here, the distance between the outermost reversal point S0 of the traverse stroke and the innermost reversal point S1 set inside by a round edge width L from the point S0 is divided by a number of points with reversal frequencies allotted to each point. A number of reversal points, corresponding to such frequencies are actually prepared at random, so that traverse movements are made by reversing at such reversal points, according to a fundamental traverse pattern set based on an edge shape of a cross-wound yarn cone. Thus, round-edge setting of the cross-wound yarn cone is easily made with a favorable edge shape while preventing ribboning.
