摘要:
A method of producing a flat tube T by bending a band-like material M to be worked, wherein the material M to be worked is pre-bent to form a pre-formed groove Md in the material M along the longitudinal center axis thereof. Thereafter, the material M to be worked is gradually moved so that both edge portions of the material M to be worked in the lengthwise direction thereof gradually approach each other with the pre-formed groove Md as a center to form a tubular shape.

A pinch valve includes a body containing an elastic tube, a cylinder body having a first cylinder portion at the upper interior part and a larger diameter second cylinder portion at the lower interior part, a first piston sliding on the inner periphery of the first cylinder portion, and a second piston sliding on the inner periphery of the second cylinder portion. The first piston is installed with a first interlocking rod having a first pressing piece at its lower end and the second piston is provided with second interlocking rods having a second pressing piece at their lower ends. The pressing pieces press the tube body from the upper and lower sides, a spring is disposed between the second piston and the first pressing piece, and an opening in the cylinder body communicates with a space enclosed by the pistons and the cylinder body.
摘要:
A multi-purpose container which is constructed by easily assemblying standing main frame members, a bottom frame member, standing side frame members and a roof frame member. The multi-purpose container is easily disassembled, to small size, for recovery. The multi-purpose container further includes door members attached to the side frame members to thereby load and unload a variety of cargo.
摘要:
A ceramic substrate according to one aspect of the invention comprises a main surface wherein a diameter of a first imaginary circle inscribed in a circumference of the main surface is represented by C (m), a thickness of the ceramic substrate is represented by h (m), a Poisson ratio of the ceramic substrate is represented by ν, a density of the ceramic substrate is represented by ρ(kg/m3), a Young's modulus of the ceramic substrate is represented by E(Pa), a deflection of the ceramic substrate is represented by X (m), the deflection being measured in a condition that the ceramic substrate is supported in a region between the first imaginary circle and a second imaginary circle which is a concentric circle of the first imaginary circle and has a diameter of C-0.01 (m), wherein X≦1.5×(C4/h2)×A and A={3×9.807×ρ×(1−ν2)×(5+ν)}/{28×(1+ν)×E} are satisfied.
摘要:
A pinch valve of the invention comprising an elastic tube body 1, a cylinder body 4 having a cylinder portion 2 and a cylinder cover 3, a piston 11 sliding on the inner periphery of the cylinder body, a pressing piece 15 fixed to a connecting portion 13 suspended from the piston, a body 16 joined to the cylinder body and having a groove 17 receiving the tube body 1, a pair of connecting body carriers 20 engaged with grooves of the body and having a through-hole 26 receiving the tube body 1, a first and a second space portions 8, 7 formed above and under the piston 11, respectively, and a pair of air ports 10, 9 respectively communicating with the first and second space portions 8, 7. The whole pinch valve is made compact in construction.
