20110200419 | SHUTTLE-TYPE CONVEYING DEVICE, MICROPLATE FEEDING AND COLLECTING DEVICE, PICKUP DEVICE FOR MICROPLATE, CASSETTE FOR MICROPLATE, AND SHELF FOR CONTAINING MICROPLATE - A shuttle-type conveying system to convey an article. The system includes a feeding and collecting device capable of setting a cassette in which articles to be conveyed are stacked as they are on a rotating and feeding table, a pickup device taking out the article and placing it on a receiving/delivery table, and a conveying device feeding the article on the receiving/delivery table to another receiving/delivery table by a shuttle conveying portion traveling on conveying paths below the receiving/delivery table. After the article is lifted up by the shuttle conveying portion and moved to outside the receiving/delivery table, the article is lowered below the receiving/delivery table and made to travel under the receiving/delivery table to another receiving/delivery table. | 08-18-2011 |
20100025908 | DISK HOLDING APPARATUS AND DEFECT/FOREIGN MATERIAL DETECTING APPARATUS - A disc holding apparatus including a plurality of movable holding claws, which have a holding section abutting to the outer circumference of a wafer having a notch and are arranged in the circumference direction of the wafer. The wafer is held by having each holding section on the inner edge side of each movable holding claw abut to the outer circumference of the wafer, thereby, at the time of detecting the notch by a sensor including a light source and a light receiving section, even when one of the holding sections abuts to the outer circumference of the wafer at a part where the notch exists, light from the light source is permitted to enter the light receiving section through the notch without being blocked by the holding section. Even when the wafer is held at the part where the notch exists, the wafer is not required to be correctly held again and throughput is improved with a shortened process time. | 02-04-2010 |
