Abstract: The present invention relates to a method for producing an acetalization product of an ethylene/vinyl alcohol copolymer by acetalization of an ethylene/vinyl alcohol copolymer, wherein the ethylene/vinyl alcohol copolymer is a porous object.

Abstract: A protector (1) has a metal header (30) that mounts a first terminal (31) and a second terminal (32) electrically isolated from one another. A metallic housing (10) is fixed to the header (30) and forms a chamber. A stationary contact (40) is electrically connected to the first terminal (31), a heater (50) is electrically connected between the second terminal (32) and the header (30), and an arm assembly (60) is arranged inside the chamber, with an end thereof being fixed to the housing. The arm assembly (60) includes an electrically conductive movable plate (70) having a movable contact (77) engageable with the stationary contact (40), a thermally responsive member (80) arranged at a position where it lies over or under the movable plate (70) and an electrically conductive weld slug (90) that fixes the movable plate (70) and the thermally responsive member (80) to the housing (10).

Abstract: A protector device (1) has a fixed electrode plate (12) with a fixed contact (12b) attached thereto and a movable electrode plate (14) with a movable contact (14b) attached thereto in which the movable contact (14b) is positioned to be able to make and break contact with the fixed contact (12b). A snap acting thermally responsive bimetallic member (15) is positioned adjacent the movable electrode plate (14) and is movable from a first position to a second position upon being heated to a prescribed temperature for causing either the engagement or disengagement of said fixed contact (12b) and said movable contact (14b). Additionally, an insulator member (13) is provided to insulate said movable electrode (14) and said bimetal member (15) from said fixed electrode plate (12) and an attachment member (17) is used to securely fix both the movable electrode (14) and the bimetal member (15) on the insulator (13).
