Abstract: PURPOSE: To prevent a printing material from leaking and a pattern from breaking by rounding a front end part of a sufficiently thick metallic plate all over the length of a squeegee blade not to be directly exposed at a lower part thereof to a screen plate. CONSTITUTION: A front end part of a squeegee blade 1 in a printing direction is circular with respect to a dotted line S-S' which is almost a central line in a thicknesswise direction of the blade. A front end part of a metallic plate 1 is made circular with respect to a center line thereof. The metallic plate is integrally formed with a structure 2 wherein a recess is formed beforehand at a central part of the circular part of the squeegee blade 1 with respect to the nearly central line all over the length in a widthwise direction. If the blade is thick, the metallic plate as a kind of a core material is inserted at the central part of the blade approximately all over the length in a longitudinal direction, so that a printing pressure necessary for metal screen plates including mesh screens can be obtained easily.  If the blade is thin or in a circular rounded structure, mesh screens are never damaged and moreover, leaking of a printing material at a return way to a starting point after printing is eliminated.

IPC: F24F7/10
Filed: 1985-06-10
Abstract: PURPOSE:To enable an efficient operation of the controller by which an optimum under-the-floor ventilation is possible by providing a circuit which emits a control output and has a function to operate an under the floor ventilation fan, when a difference in the correlative humidity between under-floor internal air and external air exceeds a preset value. CONSTITUTION:An output voltage divided by a variable resistor 4 of an under- floor internal air correlative humidity detector 1 and an output of an external air humidity detector 2 are input to a voltage comparator 3 as they are. When the output of the under-floor internal air humidity detector exceeds the external air, the output of the comparator 3 is emitted. When this output is emitted, the collector and emitter of a transistors become conductive, and a relay 5 is actuated and a motor 7 for the under the floor ventilation fan is operated. By these procedures, on a fine day, under-the-floor ventilation is carried out in a time zone of a highest efficiency, and in a time zone such as a rainy day, where so much effect cannot be expected, the under-floor ventilation is not carried out. Thus, the effective under-floor ventilation can be performed.
