Title: Blow orientating method of polyester pipe
Inventor: TAKEUCHI NAOKAZU
IPC: B29C65/00
Filed: 1983-04-06
Abstract: PURPOSE:To manufacture an orientation pipe easily even if it has a thin diameter or a thick wall, by a method wherein the diameter of an inside mandrel is made smaller than the inside diameter of unorientation polyester pipe at the time of starting of operation and orientating is done by expanding the mandrel to a normal shape at the time of orientation. CONSTITUTION:A polyester pipe extruded by an extrusion molding machine, whose temperature is adjusted to an appropriate one for orientation is transferred to a blow orientating device and orientated. Although unorientation polyester pipe 1 is orientated through air pressure blown off from a blow air hole 5 at the time of conventional orientation, a seal ring 4 of blowing-in air and an inside mandrel 3 are applied to retain necessary air pressure for the orientation. At the time of starting of operation, the outside diameter of the inside mandrel 3 is made smaller than the inside diameter of the unorientation polyester pipe 1, and the outside diameter of the inside mandrel 3 is expanded to a predetermined size after the unorientation polyester pipe 1 has passed over the inside mandrel 3.

Title: False image suppressing device of radar
Inventor: MIZUSHIRO NAMIO
IPC: H01Q17/00
Filed: 1983-04-06
Abstract: PURPOSE:To remove a false image easily by providing a planar transmission grating and a reflecting grating arranged behind it, and composing the transmission grating of conductors arranged in a diamond shape which differs in size between a long and a short diagonal. CONSTITUTION:The planar transmission grating 11 through which some of an incident radio wave W from a radar is transmitted (while the remainder is reflected as a reflected wave W1) and the planar reflecting grating 12 which reflects the transmitted wave W2 almost completely are provided. The transmission grating 11 consists of conductors 11a into diamond-shape structure which is different in size in a long diagonal direction L1 and in a short diagonal direction L2, and the angle theta between the plane of polarization (in the same direction as electric field E) of the incident wave W and the long diagonal direction L1 of the transmission grating 11 is varied to vary the intervals of the gratings equivalently, controlling the amount of transmission and the amount of reflection. Consequently, the optimum amount of transmission is set by adjusting the fitting angle of the transmission grating 11, and consequently, practical application to a reflecting wall surface is extremely easy, thereby suppressing a false image of the radar greatly.

Filed: 1991-03-25
Abstract: PURPOSE:To prevent fall-down of a packed cargo at a low cost by a method wherein a reinforcing member having a triangle cross section is mounted detachably on standing side surfaces of a packed matter which is longer in the longitudinal side and easy to fall down, with one end surface of the reinforcing member aligned with the same level as a bottom surface of an outer packing box. CONSTITUTION:An outer packing box 10 is formed of corrugated paper such as a base carton 11 to cover a bottom part of a packed matter (for example, airplane ticket vendor) 9, an outer top carton 12 and like. At this time, a reinforcing member 20 made of corrugated paper and having a triangle cross section is mounted detachably on standing side surfaces of the outer packing box 10 with one end surface 21 of the member aligned with the same level as a bottom surface of the outer packing box 10.

Title: Sampling apparatus of workpiece
Inventor: YANAGIDA NORIHIKO
IPC: G01N1/04
Filed: 1988-03-14
Abstract: PURPOSE:To enable the easy and smooth sampling of a workpiece, by a construction wherein a workpiece accommodating element is provided withdrawably off onto the downstream side of the moving direction of the workpiece and a door for opening and closing the side wall of a conveyance route is fixed to the fore end of said element. CONSTITUTION:By operating an air cylinder 7, a workpiece accommodating element 6 and a door 8 are made to project off onto the downstream side of a conveyance route 1 in the direction of conveyance of a workpiece 2. Consequently, the conveyance route 1 is put in a state wherein the width thereof is reduced by the workpiece accommodating element 6 and the door 8, and thus the workpiece 2 is transferred onto the downstream side and held in a recessed part 9 of the workpiece accommodating element 6. When this accommodation is detected by a sensor 10, the air cylinder 7 is driven to make the workpiece accommodating element 6 withdraw from the conveyance route 1. As the result, an opening 4 in the side wall of the conveyance route 1 is blocked up by the door 8 withdrawing together with the workpiece accommodating element 6.
