IPC: F16K17/30
Filed: 1983-03-10
Abstract: PURPOSE:To make convenient while to simplify the structure and operation of control valve by providing a pilot constant flow control valve independently from valve body of main valve. CONSTITUTION:When the liquid flow exceeds over setting level to exhibit high differential pressure (P5-P4) on a flow gauge 62, a diaphragm film 65 and valve body 66 will move upward to bring the opening of control valve 67 below setting level, to reduce volume of liquid flowing out through a line 42 into secondary chamber 12c. Consequently volume of liquid flowing into diaphragm chamber 12d through a communication path 43 will increase to increase the liquid pressure P3 thereby main valve body 14 will move downward to reduce opening of main valve 17 thus to recover liquid flow to setting level. Since the control valve 63 is independent from main valve 17, the structure and operation are simplified while when removing the control valve 63 from the line 42, main valve 17 can be used as double step open/close fixed flow valve to improve utilization.

Abstract: PURPOSE:To produce continuously a decorative panel having a beautiful coated surface by providing a rectifying zone between a draining and drying stage and a coating stage when a cut sheet is successively sent from a pretreating stage to the draining and drying stage and the coating stage. CONSTITUTION:When a cut sheet which is previously formed into the desired shape is sent successively from a pretreating stage to a draining and drying stage 2 and a coating stage 3, many cut sheets which are continuously sent in are collected to the guide wall side 17 between the stage 2 and the stage 3 by an oblique roller 19, rectified and sent to the downstream side. Namely, the mode of the flow of the cut sheets becomes normal immediately before the coating stage where rectification is especially required and the coating can be carried out in exactly the same way as in the conventional coating of a strip. A decorative panel having a beautiful coated surface can be thus produced.

Abstract: PURPOSE:To obtain the title material wherein the re-crystallization of a dicyanoimidazole dye is prevented and no density irregularity is produced by setting the dye in a colorant layer to a specific value or more in a wt. ratio with respect to the binder in the colorant layer and using at least two or more kinds of dyes belonging to the dicyanoimidazole dye as the dye. CONSTITUTION:For example, a thermal transfer material for many-time recording is formed by providing a colorant layer 2 on a base material 1 and further providing a lubricating layer 3 on the colorant layer 2. As the base material 1, various polymer films are desirable and, for example, there is a film obtained from polyester or polyamide. The colorant layer 2 consists of at least two or more kinds of dyes belonging to a dicyanoimidazole dye and a binder. The amount of the dyes to that of the binder in the colorant layer 2 is 1.0 or more in a wt. ratio. When the dicyanoimidazole dye is compounded alone in the wt. ratio of 1.0 or more with respect to the binder, re-crystallization is generated but, when two or more kinds of dyes of the same system are compounded and the total amount of the dyes is set to 1.0 or more in a wt. ratio, re- crystallization becomes hard to generate.
