  • Publication number: 20080314564
    Abstract: A temperature control device controls the temperature of a controlled object by circulating a fluid in a temperature adjustment unit arranged near the controlled object. The temperature control device comprises a heating pathway that heats and circulates the fluid in the temperature adjustment unit, a cooling pathway that cools and circulates the fluid in the temperature adjustment unit, a bypass pathway that does not pass the fluid through the heating pathway and cooling pathway, but circulates the fluid in the temperature adjustment unit, and adjustment means that adjust a flow ratio of the fluid that is supplied from the heating pathway, cooling pathway, and bypass pathway to the temperature adjustment unit via a confluence unit that combines these flows. The adjustment means are provided on a downstream side of each of the heating pathway, the cooling pathway, and the bypass pathway and on the upstream side of the confluence unit.

  • Patent number: 6913031
    Abstract: A flow controller and a flow controlling method are adapted to be released from conventional restrictions by using a novel type called a pulse shot type. A pulse shot (opening/closing operation of a first cutoff valve (12) and, after that, opening/closing operation of a second cutoff valve (17)) is repeated. Simultaneously, a volume flow Q of process gas exhausted from the second cutoff valve (17) per unit time on the basis of after-filling pressure and after-exhaust pressure of the process gas in a gas filling capacity (13) measure by a pressure sensor (14). Furthermore, a mode of the pulse shot is changed to control the volume flow Q of the process gas exhausted from the second cutoff valve (17) per unit time.
