An immunoisolatory vehicle for the implantation into an individual of cells which produce a needed product or provide a needed metabolic function. According to such a constitution, the efficiency of exciting the film to be treated is significantly promoted since electron excitation effect by the ultraviolet light irradiation is added to vibrational excitation effect by the infrared light irradiation and strain energy caused in the film to be treated by the lamp annealing process is removed or reduced by a furnace annealing process. The second detecting body rotates in association with the first detecting body at a different speed therefrom, and the second detector detects rotation of the second detecting body. The workpiece gripping member is also rotatable about a third axis substantially transverse to the first and second axes so as to be capable of rotating the workpiece from a first angular position at the anvil to a second angular position.
