An eccentric orbiting type planetary gear device includes a bearing which requires no pre-load adjustment. The planetary gear device is small in the number of components when compared with the conventional device, and is improved in performance and in assembling efficiency. In manufacturing an eccentric orbiting type planetary gear device in which a supporting block (31) is made up of a supporting member (32) having a plurality of pillar-like portions (32a), and a disk (33), the supporting member and the disk being fastened to each other with fastening members (35) with an external gear (21) between the supporting member and the disk in such a manner the external gear is engaged with an internal gear; the supporting member and the disk are abutted against each other through end faces thereof, and are fastened to each other to form the supporting block, and bearing rolling surfaces (32b) and (33a) corresponding to inner races are formed in the supporting member and the disk at a predetermined interval.

A plasma processing apparatus having a focus ring, enables the efficiency of cooling of the focus ring to be greatly improved, while preventing an increase in cost thereof. The plasma processing apparatus is comprised of a susceptor which has an electrostatic chuck and the focus ring. A wafer W to be subjected to plasma processing is mounted on the electrostatic chuck. The focus ring has a dielectric material portion and a conductive material portion. The dielectric material portion forms a contact portion disposed in contact with the electrostatic chuck. The conductive material portion faces the electrostatic chuck with the dielectric material portion therebetween.

Provided is a relative pressure control system has a simple configuration, but enables accurate regulation of a division ratio of an operation gas, and concurrently makes it possible to securely drain the operation gas from an operation gas pipeline in case of emergency. The system includes a plurality of air operated valves of a normally open type that are connected to an operation gas pipeline supplied with an operation gas; pressure sensors that are series connected to the respective air operated valves and that detect output pressures of the respective air operated valves; a controller that controls operation pressures of the respective air operated valves in accordance with the pressures detected by the pressure sensors; and a hard interlock solenoid valve that correlates the plurality of air operated valves to one another so that at least one of the plurality of air operated valves is normally opened. In the configuration, an opening of a specified one of the plurality of air operated valves is regulated, the operation gas is output at a predetermined division ratio.

A vacuum process system comprises: a load port on which an object to be processed is set; a common transfer chamber disposed adjacent to the load port, having an internal space set at an atmospheric pressure level, and including a first transfer device that is movable and transfers the object into/from the load port, the first transfer device being disposed within the internal space; and a process unit having one process chamber for subjecting the object to a predetermined process, and a vacuum transfer chamber connected to the process chamber, having an internal space set at a vacuum pressure level, and including a second transfer device for transferring the object into/from the process chamber, the second transfer device being disposed within the internal space. The process units are individually connected to the common transfer chamber such that the process units are substantially parallel to each other. The vacuum chamber of each process unit is connected to the common transfer chamber. Each process unit extends linearly in a direction substantially perpendicular to the common transfer chamber. The object is transferred into/from the vacuum transfer chamber by means of the first transfer device.
