  • Publication number: 20050029369
    Abstract: A partial pressure control system 45 includes two valves 2 which are branched from an operation gas supply pipe 44 and which variably control operation gas, pressure sensors 3 which are respectively connected to the each valves 2 in series and which detect pressure of the operation gas, and a controller 25 which proportionally controls the operation of the valves 2 based on detection result of the pressure sensors 3, thereby relatively controlling pressures P1 and P2 of the two valves. With this configuration, it is possible to reduce wastefull consumption of the operation gas, and to enhance the responsivity with respect to change of setting and the like.

  • Publication number: 20040240971
    Abstract: Suppressed are shock waves occurring when opening a gate valve between two vacuum chambers and peeling of particles by a viscous force taking place when a gas is supplied into a vacuum chamber, whereby contamination of a substrate by particles is suppressed. If one vacuum chamber is a substrate processing chamber for performing a vacuum process on the substrate and the other chamber is a transfer chamber having a substrate transfer device therein, the gate valve is opened when inner pressures of both the vacuum chambers are less than 66.5 Pa and a higher one thereof is less than twice a lower one thereof. Preferably, a purge gas for peeling of particles is supplied, before supplying the purge gas for pressure control, into the substrate processing chamber with a flow rate greater than that of the purge gas for pressure control.

  • Publication number: 20040216475
    Abstract: A semiconductor processing system includes a control section that switches a thermo-medium circulation apparatus between an ordinary mode and an energy-saving mode in correspondence with an ordinary operation state and a long idle state of a processing apparatus, respectively. The long idle state is an idle state of the processing apparatus longer than a predetermined threshold time period. A thermo-medium is circulated at a first flow rate and at a second flow rate smaller than the first flow rate in the ordinary mode and the energy-saving mode, respectively. The control section refers to recipe information on a process sequence, thereby detects that the processing apparatus will shift from the ordinary operation state to the long idle state, and switches the thermo-medium circulation apparatus from the ordinary mode to the energy-saving mode after the processing apparatus shifts to the long idle state.

  • Patent number: 6645405
    Abstract: An unstable weighing due to the plunger sliding resistance in a prepla type injection molding machine is prevented by dividing control of the plunger retraction movement for the weighing into speed control and pressure control. A plastic resin supply start position and a forced retraction release position are set along the way of the plunger retraction stroke by reference to a weighing start position. A plunger is moved from the weighing start position after injection and pressure-keeping to a weighing stop retraction position. Plastic resin is supplied to the forward portion of the injection cylinder when the plunger attains the supply start position from the weighing start position. The plunger is moved by forced retraction up to the forced retraction release position by speed control; the weighing is stabilized by changing the speed control to the pressure control once the plunger attains the forced retraction release position.

  • Patent number: 6606912
    Abstract: A construction for mounting a pressure detector prevents the detector diaphragm from being strained by stress applied to the pressure detector as the detector is mounted in a fixture main body provided in a pipe line or the like, thereby keeping the output characteristics and temperature characteristics of the detector from greatly differing before and after the mounting. The pressure detector is constructed by combining and fastening together a diaphragm base having a diaphragm and a sensor base having a sensor element therein that is activated by displacement of the diaphragm base. The pressure detector, with a gasket placed thereunder, is disposed in a mounting hole of a fixture main body that is mounted in a pipe line. The pressure detector is air-tightly pressed and fastened by a presser member inserted from above in the mounting hole.
