Title: Printing apparatus
Inventor: TAWARA HIROSHI
IPC: B41J11/13
Filed: 1989-10-23
Abstract: PURPOSE:To obtain a printing apparatus with high printing quality and good running characteristic of a tape by providing right and left side plates, each with a hole larger than a second shaft, at the rear end of a platen frame provided with a jaw part for guiding a leading end of a printing paper. CONSTITUTION:In this printing apparatus, a platen frame 14 is supported by a first shaft 15, a second shaft 16 and left and right side plates 23, 24. The second shaft 16 if fixed to one point by a fixing ring 25. After a printing paper 22 guided by a frame 21 from a paper feed roller 20 is set at a predetermined set position, a printing head 11 is moved to be brought into pressed contact with a platen rubber 12. The second shaft 16 is moved to an upper end within a hole 26 of each side plate around the first shaft 15 at the front face of the platen frame 14, so that the platen frame is turned movable in the same direction as the movable direction of a platen. Since a leading end of the printing paper 22 is in touch with a jaw part 14b of the platen frame 14 when the printing paper 22 is sucked in, the platen frame 14 is consequently turned movable. Accordingly, a printing apparatus with high printing quality and smooth running characteristic is obtained.

Title: Tacky adhesive tape slowly releasing active chlorine
Inventor: KAMAGATA KAZUO
IPC: C09J7/02
Filed: 1992-09-18
Abstract: PURPOSE:To gradually release active chlorine in the presence of moisture in air and to obtain a high sterilization effect by forming a tacky adhesive layer on one surface of a base material having air permeability and fixing solid chlorine agents to its surface in the state of partly exposing the tacky adhesive layer. CONSTITUTION:This tacky adhesive tape is produced by previously forming the tacky adhesive layer 2 by a transfer method on one surface of nonwoven fabric as the base material 1 having the air permeability, spraying and fixing the powdery or granular solid chlorine agents 3 on the front surface of the tacky adhesive layer 2 so as to partially expose the tacky adhesive layer 2 and cutting the base material to a tape form of a prescribed width. The tacky adhesive tape is stuck to the joint parts of tiles of a bath room on which black fungi are formed, at the time of use. As a result, the moisture of the bath room comes into contact with the solid chlorine agents and gradually dissolves the agents. The black fungi are decomposed by the gradually released active chlorine. The tacky adhesive tape is peeled from the tiles and is discarded when the whitened state resulted from the decomposition of the black fungi is observed from the rear surface of the tacky adhesive tape.

For example, after the exposed parts 4a and 4a are made in contact with each other, they are heated and welded by a burner 7, then both fine adjustment stages 3 and 3 are finely moved in an opposite direction to draw the optical fiber. Therefore, drawing is performed slowly, temperature distribution by heating, that means, a welded state is made uniform in a diameter direction and each optical fiber is uniformly drawn in an optical axis direction while it is welded, so that circularity is held. Thus, the work for making the outside diameter of the optical fiber small is not necessitated and the dependency on polarization is reduced.
