Abstract: PURPOSE:To prevent a push-up pin from being damaged due to abnormal shifting of a travelling table without fail by a method wherein a round part to be detected corresponding to the fixing range of a semiconductor element as well as a detector of the detected part are provided on the travelling table. CONSTITUTION:When a driving system 8 erroneously inputs data to a controller in case of setting up the position of each die 1 or the controller is erroneously actuated to shift a travelling table 5 exceeding the inner diameter range of a wafer ring 3, an edge of hole 10 as the part to be detected is detected by a detector 12 to transmit an emergency-stop signal. The controller receiving this signal is turned to the emergency-stop mode to emergency-stop motors 9a, 9b. Through these procedures, the travelling table 5 is immediately stopped to prevent a push-up pin 4 from being damaged due to collision with the wafer ring 3 or a round hole part 6 of the travelling table 5.

IPC: B65H3/46
Filed: 1982-09-22
Abstract: PURPOSE:To feed dry air to a desired place of a copying machine securely and to regenerate silica gel without replacing it, by providing plural chambers and performing humidification and dehumidification. CONSTITUTION:Air from an air generation source 16 is admitted into the chamber 2 of a container 1 from a pipe 15 to absorb moisture by the silica gel and then, hot air is fed through a pipe 23 to supply the dry air to the desired part of the copying machine. The silica gel 5 in the other chamber 3 which has lost its dehumidifying function is supplied with a hot air from a hot air generator 14 through a pipe 13. The hot air is discharged from a pipe 4. Thus, the silica gel 5 is regenerated. When the silica gel 6 in the chamber 2 loses its moisture absorbing function after specific-time moisture absorption, a motor 17 is driven to rotate a driving gear 18, gear 19, and shaft 21, and then the silica gel is moved onto the pipe 13 to recover its function. The silica gel 5 after the function recovery is present over the pipe 15.
