摘要： A liquid agent evaporator includes a sealed container accommodating a liquid agent therein and having a generally flat upper internal face and a vapor outlet, a carrier gas feeder for feeding the carrier gas into the sealed container, and a carrier gas blower provided in the upper internal surface of the sealed container for blowing the carrier gas fed from the carrier gas feeder so that the blown carrier gas comes into contact with substantially the entirety of the upper internal surface of the sealed container. The carrier gas blower is provided, for example, at the center of the upper internal surface of the sealed container and blows the carrier gas radially at an initial velocity directed at least to the upper internal surface side of the sealed container. The carrier gas blower can include a gas blow tube which is communicated with a gas feed tube and has a plurality of gas outlets formed on the top face side of the gas blow tube. By translating the gas blow tube so that the top face thereof comes to be in close proximity to the top face of the sealed container, the carrier gas blown from the gas outlets can reach substantially the entirety of the upper internal surface of the sealed container.

摘要： In oxide film removing equipment for removing a SiO.sub.2 film on a semiconductor substrate by using hydrogen fluoride, a liquid mixture of hydrogen fluoride and methyl alcohol is prepared in a chemical factory beforehand. The liquid mixture of hydrogen fluoride and methyl alcohol is heated to generate azeotropic vapor at a semiconductor works and the vapor is used to remove the SiO.sub.2 film on the substrate. The liquid mixture of hydrogen fluoride and methyl alcohol previously prepared in the chemical factory increases safety during an operation at the semiconductor works.

摘要： A movable yoke-type lifting magnet device including a main core wound with a coil and at least one yoke magnetically coupled to the core. The movable mechanism of the yoke enables the yoke to freely follow the contour of a workpiece to be lifted. An auxiliary core may be provided between each said at least one yoke to provide a yoke-type lifting magnet device. The auxiliary core greatly increases the magnetic forces induced between the cores and the yoke. Combination of the magnetic coupling between the yokes and the core and the provision of the auxiliary core provides a movable yoke-type lifitng magnet device wherein the yoke can freely follow the contour of a workpiece and the magnetic forces between the cores and the yoke are greatly increased. Such a combination prevents the yoke from slipping relative to the cores and stable lifting is possible.
