Patent number: 6203249Abstract: A particulate object conveying device is provided, and the conveying device includes a stagnating portion. A rotor has an outer circumference having a plurality of grooves formed equidistantly about the outer circumference, the grooves being of a size and shape to hold a single one of the particles of predetermined size. The rotor rotates within the stagnating portion. A discharge path is provided for discharging the particles from the rotor.Type: GrantFiled: September 29, 1998Date of Patent: March 20, 2001Assignee: Mitsui High-tec Inc.Inventors: Migaku Ishida, Akikazu Higuchi

Patent number: 6102629Abstract: The present invention relates to a device for conveying spherical articles at high speed between sequential processes having different protective atmospheres, where the leakage of the atmospheres, which must be converted between the sequential processes, is prevented. The device includes a structure incorporating a rotary relay having a plurality of spherical-article accommodating chambers formed at predetermined intervals, a support container closely mounted on the rotary relay, and having a spherical-article receiving passage and a discharge passage. An atmosphere discharge pipe communicates with the spherical-article accommodating chambers of the rotary relay, and an atmosphere supply pipe is disposed adjacent to the spherical-article discharge portion of the rotary relay and communicates with the accommodating chambers.Type: GrantFiled: June 17, 1998Date of Patent: August 15, 2000Assignee: Mitsui High-tec Inc.Inventors: Migaku Ishida, Katsumi Amano, Akikazu Higuchi, Shuho Kai
