Title: Extruding method of molten resin extruder
Inventor: OOTA YUKIO
IPC: B29C48/38
Filed: 1983-11-01
Abstract: PURPOSE:To contrive protection of each element and early stabilization of a process, by a method wherein at least two or more of bleed valves are provided on upstream side of a gear pump, a filter and a metallic cap, and a foreign matter and modified resin are discharged out of series by opening the valves in order from the upstream side at the starting time of extrusion. CONSTITUTION:An extruder 1 is driven by opening a bleed valve 17 at the starting time of extrusion. Modified resin and a foreign matter in piping 6 are extruded out of series through the valve 17. When a discharged molten resin is turned into a normal state, the valve 17 is closed and a downstream side bleed valve 18 is opened. In this instance, although the molten resin passes through the inside of a gear pump 8, damage of the gear 8 and a gear case 9 is prevented. As for the valve 18, as the molten resin which has been retained within a gear pump 7 and piping 10 is discharged the modified resin and a foreign matter do not enter into a filter 11 side. After completion of discharge the valve 18 is closed and a bleed valve 19 is opened. Then the modified resin and the foreign matter in the filter 11 and piping 14 and a foreign matter to be mixed from the outside at the time of exchange of either filter 11 or a mouthpiece 15 are discharged along with the molten resin.

Title: Water-leakage detector of water-proof hausing
Inventor: SUZUKI NOBUO
IPC: B65D25/02
Filed: 1989-08-08
Abstract: PURPOSE:To accurately detect water-leakage with a simple structure by providing a structure to take a detector around water-paths in the case of water- leakage. CONSTITUTION:The body 1a of a water-proof hausing 1 is a circular, square or angular cylinder with an opening at the one end thereof to which a cap 1b is attached. And a drawing portion for cables is provided at the other closed end thereof. In this case, a water-leakage detecting head 10 is designed to move around in a spiral direction for instance along the inner face of the body 1a and hence, the detecting parts can be arranged at all of the periphery and full of the length of the body 1a at which water may leak. When the leaked water even from any directions flows along the inner face, the water comes in contact with the detecting head 10 immediately to change the resistance of the detecting head 10 and detect the water-leakage. In this way, even if the water-proof hausing 1 is submerged in any optional directions or positions in water, water-leakage can be detected before devices contained in the inside thereof are submerged in water.
