Title: Impact wire type serial recorder
Inventor: YAMAGUCHI NAOTO
IPC: B41J2/24
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To perform draft printing even on a corner portion of a recording medium by moving a recording head in a low speed. SOLUTION: Upon a stage wherein printing on a top end or bottom end of a recording medium M is necessary, the recording medium is conveyed to a position where the top end or bottom end is not overlapped with a window 9 of a ribbon mask 10 (I). Next, the recording medium is conveyed to a position where the top end or bottom end of print data can be printed (II). A carriage is moved in a low speed Vs which is lower than a moving speed for a draft printing mode irrespective of a designated printing mode (III, IV) and data of dot pattern having a density suitable for the printing mode is outputted to a recording head.  Since the recording head is conveyed in a low speed when the printing on a corner region on the top end or bottom end is performed, it is possible to prevent convolving of the corner portion of the recording medium with the window of the ribbon mask that may occur at the high speed moving, thereby enabling the printing in the draft mode.

IPC: C03B8/02
Filed: 1985-02-05
Abstract: PURPOSE:To dry a tubular gel uniformly and rapidly in high yield without deformation, by drying the tubular gel while flowing a gas containing vapor of a dispersing medium of a sol under controlled vapor pressure thereof from the inside and outside of the tubular gel in the titled production by the sol-gel method. CONSTITUTION:A silica sol consisting essentially of an alkyl silicate and fine powder silica as main raw materials is put into a cylindrical container, and gelatinized while rotating around a tubular axis to prepare a tubular gel. The resultant tubular gel is then dried to give a dried gel, which is sintered and vitrified to produce a quartz glass tube. The tubular gel is dried by flowing a gas containing a dispersing medium of the sol under controlled vapor pressure from the inside and outside of the tube. Thus, the unevenness of the drying is eliminated, and therefore the yield and warpage are improved. The tubular gel can be dried rapidly in a smaller vessel at a lower gas flow rate than in the conventional method.

Abstract: PURPOSE:To have a transporting force generated by itself also in the axial direction of a plate-like body as a roll is rotated by slantly protruding flexible wire-like bodies on one end side of a feed roll incorporated in various transport devices. CONSTITUTION:A roll 10 is formed by slantly protruding many wire-like bodies 3 on the right end side of the roll 10. If the roll 10 is rotated in the direction as shown in the figure, a plate-like body 4 is transported in an arrow direction 5; and if it is rotated in the direction opposite to that in the figure, the body 4 is transported in an arrow direction 6. In addition, if the roll 10 is rotatably supported and the plate-like body 4 is transported from an arrow direction 8, its transportation direction is changed to an arrow direction 6. Now, if the self- weight F of the plate-like body is applied to the free end 9 of the wire-like body 3, the free end 9 is displaced in the axial direction with respect to the fixed end 11 so as to bend to a state shown by a two-dot chain line. This displacement is continuously repeated in many wire-like bodies 3 as the roll 10 is rotated, thus a transporting force is generated also in the axial direction.
