摘要： An arc melting furnace apparatus is provided which reduces an operation burden on a worker and shortens working hours. An arc melting furnace apparatus 1 includes a housing 2 having formed therein a melting chamber 2a, a hearth 4 provided within the melting chamber 2a and having a recessed portion 4a, and a heating mechanism 10 for heating and melting a metal material supplied into the recessed portion 4 to generate an alloy ingot. The apparatus comprises a turning member 23 rotatably supported on a supporting member 21 standing within the melting chamber 2a, a perimeter edge of the turning member 23 rotating and moving along the inner surface of the recessed portion 4a to lift the alloy ingot generated in the recessed portion 4a above the hearth 4 and turn it over, and a resilient turn-over assisting member 24 provided above an upper end of the recessed portion 4a. Further, the turn-over assisting member 24 is arranged to flex by a predetermined amount when the alloy ingot abuts it, and to return to its original state from the flexed state so that the alloy ingot is urged to drop into the recessed portion 4a.

摘要： A screw fluid machine is disclosed particularly for use as a vacuum pump. The machine consists of a male rotor (301) having teeth mated with a female rotor (302) and mounted for rotation in a casing (109) to form fluid chambers. Discharge ports (304,305) are formed in a screw end face plate (303a,303b) constituting a part of the casing (109) so that an end face of the teeth of each rotor (301,302) opens and closes each discharge port (304,305). A set of discharge ports (304) are provided on the male rotor side whose number is smaller than the total number of teeth of said male rotor (301) and a set of discharge ports (305) are provided on the female rotor side whose number is smaller than the total number of teeth of said female rotor (302). Each of the discharge ports (304,305) are provided with a pressure adjustment device (307) which opens when the pressure in said chambers exceeds atmospheric pressure.
