A durable protective tube for a thermocouple having an extended serviceable life is obtained by covering a tubular preform of ceramic material with a refractory coating. The refractory coating is an alternate arrangement of one or more fine refractory layers of fine particulate refractory material having a particle size of 150 mesh to 500 mesh and one or more coarse refractory layers of coarse particulate refractory material having a particle size of 0.1 mm to 2.0 mm. The refractory coating is prepared by alternately applying a slurry of fine refractory particulates in a colloidal silica or ethyl silicate hydrolyzate binder and then coarse refractory particulates on the outer surface of the tubular preform followed by optional sintering.

A mold surface treatment process comprises: providing a fluidized bed of a treating powder; holding the mold in the fluidized bed to fill up the depressions of the mold surfaces with the treating powder by employing a surface treating member for pushing the treating powder into the depressions; and taking the mold out of the fluidized bed. The mold surface treatment allows to make molten metal less likely penetrate into the walls of mold, and to manufacture a mold which generates less amount of gum causing defects during casting.
摘要:
A composite material having a first metallic material as the matrix material and extremely fine particles of diameters of the order of tens to hundreds of angstroms of a second metal dispersed in this metallic matrix material is obtained by rapidly adiabatically cooling vapor of the second metallic material through a nozzle, and squirting a jet of fine particles produced thereby into a molten mass of the first material. Optionally, inert gas may be squirted through the nozzle along with the vapor of the second metallic material.
摘要:
A mold comprising a cavity for defining the shape of a casting and a mold body for forming said cavity, comprising: a mold body formed of an ordinary temperature setting resin or thermosetting resin and casting sand, said mold body having a surface layer portion on the surfaces thereof including depressions, said depressions in the surface layer portion being filled up with at least one porous powdered material selected from the group consisting of hydrous magnesium silicate clay mineral, activated carbon and activated alumina, thereby providing the mold body with smooth surfaces whereby said mold generates less amount of material such as gums which cause defective castings during casting since molten metal is restrained from intruding into the walls of said mold.

摘要:
A seatbelt alarm device for a vehicle includes a seat sensor, a seatbelt sensor, a judgment circuit, an alarm unit, and a child seat sensor. The seat sensor detects a mass on a seat of the vehicle. The seatbelt sensor detects whether a seatbelt of the seat is engaged with a seatbelt buckle. The judgment circuit generates a demand for a seatbelt-wear alarm upon determining that a mass sits on the seat and the seatbelt is not engaged according to detection signals of the seat sensor and the seatbelt sensor, respectively. The alarm unit generates the seatbelt-wear alarm. The child seat sensor detects a child seat mounted on the seat. The judgment circuit restricts operation of the alarm unit when the judgment circuit determines that the child seat is mounted to the seat according to a detection signal of the child seat sensor.
