The present invention relates to a jacket heater having a heating element built therein, the jacket heater containing: the heating element having a watt density of 0.15 W/cmor more, a metal foil disposed adjacently to the heating element, and a surrounding body which surrounds the heating element and the metal foil.

Jacket heater and method for attaching same

The present invention provides a covering member including: a surrounding member including a heat insulating material and having a heat generating member or a heat insulating function, the surrounding member being wound from an open state so as to cover an object; and a fixing unit including: an engagement member including: a ring including a heat resistant elastic material; and a hook fitted to the ring; a holding member disposed on one end of the surrounding member, the holding member fastening the ring of the engagement member to hold the engagement member; and a receiving member disposed on one end of the surrounding member so as to correspond to the holding member, the receiving member including a receiving metal fitting to be engaged with the hook of the engagement member.

Covering member and heating device

A covering body for heating a pipe to be attached to the pipe and to conduct external heat to heat the pipe, including: a surrounding body including at least two parts having a divided shape of a cylindrical body along an axial line of the cylindrical body, the surrounding body having: a through hole having a diameter corresponding to an outer diameter of the pipe; and a concave groove provided on an outer peripheral surface of at least one of the at least two parts and extending in a longitudinal direction of the surrounding body, a fitting member including: a first fitting plate including a first arc band-shaped plate longer than a half of circumference of an outer peripheral surface of the surrounding body and having a first extended portion and a first cutout at one end of the first arc band-shaped plate; a second fitting plate including a second arc band-shaped plate longer than the half of circumference of the outer peripheral surface of the surrounding body and having, at one end of the second arc band-shaped plate, a second extended portion and a second cutout to be engaged with the first cutout and the first extended portion; and a hinge openably and closably combining the other ends of the first arc band-shaped plate and the second arc band-shaped plate each other, the fitting member being attached on the surrounding body so as to fit the hinge in the concave groove and fit the first extended portion to the second cutout.

An in-situ porous inorganic material with a skeleton structure of aluminum borate whiskers, and a whisker-reinforced metal-matrix composite material including the porous inorganic material as a reinforcement, has aluminum borate whiskers distributed uniformly and randomly therein. Each of a plurality of the aluminum borate whiskers is bonded to at least another one of the aluminum borate whiskers at a bonding site, which is formed from aluminum borate common to and constituting part of each one of the aluminum borate whiskers bonded at the bonding site. A process of producing the in-situ porous inorganic material includes the steps of firing a compact of mixed powder including an aluminum compound, a boron compound, and a nickel compound and thereby in-situ synthesizing the aluminum borate whiskers.

This invention relates to a shaped fibrous material for use in the manufacture of fiber-reinforced metals comprising a uniform mixture of ceramic fibers and aluminum borate whiskers. The invention also relates to a method for producing the shaped fibrous material comprising the steps of dispersing ceramic fibers and aluminum borate whiskers in a suitable solvent containing a binder to form a slurry, transferring the slurry into a suction molding, aspirating and dehydrating the slurry to form a shaped dehydrated fibrous material, and drying and firing the shaped dehydrated fibrous material to obtain the shaped fibrous material. The shaped fibrous material can be cast efficiently into a fiber-reinforced metal with a high yield. The thus produced fiber-reinforced metal has a high wear resistance combined with a very mild nature of attacking the mating member.

A process of production of alumina short fiber reinforced magnesium or magnesium alloy product features formation of alumina short fiber pre-form utilizing a inorganic binder which is composed of one or more oxides having thermodynamically stability equivalent to or higher than MgO. In the alternative, the composite almina fiber and binder surfaces of the alumina short fiber pre-form can be coated by a baked coating layer. Pressure casting of molten magnesium or magnesium alloy is then performed for forming the final products.
