Title: Edge working method in pipe bias cutting and its edge working device
Inventor: KAWAKAMI MASAMICHI
IPC: B23K7/00
Filed: 1979-05-24
Abstract: PURPOSE:To subject a branch pipe to Y-type edge preparation and improve working efficiency by providing a roller which advances at all times in the cutting direction based on the intersecting line of pipe and letting an edge working torch follow up the turning motion of the roller in synchronization with the same at a fixed groove angle. CONSTITUTION:A guide roller 31 is placed at the top end of the pipe 7 on turning rolls 3. Next, the edge working torch 41 of the torch 39 near the roller 31 is set at a fixed groove angle with respect to a cutting torch 40. Thence, the pipe 7 is preheated by the torch 39 and is rotated in the arrow A direction by the rolls 3. At this time, a timer drive unit 16 moves a carrier 17 in the arrow C, D directions in synchronization with the intersecting line according to the revolution of the pipe 7. Then, by the existence of offset L between the roller 31 being supported by the carrier 17 and axial center 27a, the advancing direction of the roller 31 is maintained always in the composite direction of the revolving direction of the pipe and moving direction of the carrier, that is, in the cutting direction based on the intersecting line of the cutting torch 40. The turning motion of the roller 31 causes the edge preparation torch 41 to turn at the set groove angle by way of a gear 33, shaft 35 and gears 47, 43.

Title: Dust collecting device
Inventor: KAWAMOTO YASUSHI
IPC: E01H1/08
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a dust collecting device capable of cleaning in running at higher speeds by preventing capacities of cleaning by right and left side brushes from making a big difference and further shortening a time for transportation by air flow. SOLUTION: A right side dust swept out by the rotation of a right side-brush 4 and a sweep-out brush 7 is taken into a sucking device 10 without almost a time difference from a left side dust swept out by the rotation of a left side- brush 5. The width of the sucking device 10 itself is reduced so that even dust taken into the sucking device 10 at a position apart mostly from a sucking port 34 is positioned nearer the sucking port 34 than before and its air flow transportation time is also shorter than before. Thus, the dust swept out between the right and left side-brushes 4 and 5 is sucked into the sucking port without almost a time difference, and any large difference of cleaning capacity is not made between the right and left side-brushes 4 and 5.

IPC: B41J2/255
Filed: 1979-05-23
Abstract: PURPOSE: To make the recorder ease to read through uniform contrast as a whole,  by changing the power fed to heating elements depending on the size of recorded characters.  
     CONSTITUTION: A heat sensing head TH arranging 20 sets of heating elements TH 1 WTH 20  on a line on the plane opposing to a recording paper on a rotary member 25 of a carriage 11 is provided so that the lower end is in matching with the rotary center of the member 25. Further, when the member 25 turns, the head TH is latched at a position in agreement with marks a'Wc', and the head TH is tilted for the purpose to change the size of letters. In case of recording on a straight line O-O' with the head TH, if the line is orthogonal to the straight line P, the elements TH 1 WTH 20  are almost heated at the same time, and the trace of recording is as RT 1 WRT 20  of length LA. Further, when the head TH is tilted by b θ  and shifted toward P on the straight line O-O', the elements are sequentially heated from TH 1  to obtain the trace of LB. Similarly, the straight line LC having shorter length is obtained. Further, the drive voltage is lowered as the size of letters is smaller. Thus, the recording easy to see with uniform contrast entirely can be obtained.
