    Abstract: A liquid chemical supply system includes a liquid chemical pump having a pump chamber for supplying a liquid chemical and a volume variation member that will vary the volume of the pump chamber, and will intake or discharge the liquid chemical based upon a change in the volume of the pump chamber in accordance with the volume variation member. The system also comprises an operation means for causing the volume variation member to operate, an operation amount detection means for detecting the operation amount of the volume variation member, a displacement control means for performing displacement control so that the volume variation member will be displaced by the operation means when liquid chemical ports that lead to the pump chamber are in the closed state, and a determination means for determining the presence or absence of gas inside the pump chamber based upon the operation amount detection results from the operation amount detection means during displacement control.

    Abstract: A chemical liquid control valve is provided with a barrier on an outer circumferential end portion of a protruding part (an outer circumferential bottom portion of a valve seat). The barrier is placed so that an angle between the center line of an outlet passage and the line extending between the center of a valve port and each end of the barrier. The barrier is designed to have a height relative to a contact surface of the valve seat with a valve element is substantially half of the travel distance of a diaphragm valve element.

    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.

    Abstract: According to the present invention, electrorheological fluid is deaerated after it is sealed in a closed device which is operated by the electrorheological fluid. Thus, it is possible to control the operation of the closed device in accordance with an electric field. Additionally, the control of viscosity is not affected by repetitive operations of the closed device, thereby obtaining a closed device having a smooth operation and good repeatability. The deaeration is achieved under a predetermined reduced pressure, for example, of not more than 100 torr. In addition thereto, a suitable heating process is carried out as required.

    Abstract: A diaphragm valve capable of increasing durability of a diaphragm comprises a valve body internally formed with a valve chamber having an open upper end and a suck-back chamber having an open lower end, between an inlet passage and an outlet passage, and a through hole which provides communication between the valve chamber and the suck-back chamber. The open end of the valve chamber is closed by a first diaphragm which is brought into and out of contact with a valve seat. The open end of the suck-back chamber is closed by a second diaphragm. The first and second diaphragms are substantially identical in shape. Each circumferential edge portion of the first and second diaphragms is tightly retained by a retaining member mountable to the valve body so that the diaphragms are curved outwardly with respect to the valve chamber and the suck-back chamber respectively. The first and second diaphragms are connected by a connecting rod passing through the through hole so that the diaphragms are deformed synchronously by operation of an actuator.
