    摘要： An apparatus for injecting constant quantitative chemicals which is capable of injecting a chemical solution into ultra pure water without generating particulate contamination, and furthermore, the injection interval of the chemical solution to the cleaning nozzle is controlled in units of seconds within a range of a few seconds to 10 or more seconds, and the switching of the type of chemical solution and the changeover to ultra pure water cleaning can be conducted in a short period of time of approximately 1 second.The apparatus includes a chemical solution injection system having a chemical solution retaining part for retaining the chemical solution, a control system for pressurization and depressurization for controlling the pressure of the chemical solution in the chemical solution retaining part at regular intervals, an injection control system which operates in concert with the control of the pressure of the chemical solution, and is structured so as to conduct the intermittent injection and instantaneous mixing function of the chemical solution from the chemical solution injection system to the ultra pure water flow path, and the injection stoppage function, and a chemical solution replenishment system which is structured so as to operate in concert with the control of the chemical solution and to be capable of replenishing the chemical solution in the chemical solution retaining part from a chemical solution source.

    摘要： A fluid control valve, which can control a fluid having a pressure in the order of 10 kg/cm2, has a response time in the order of several milliseconds can be made small in size, and a fluid supply/exhaust system that provides less gas counter flow in the event of a plurality of valves being used. A fluid control valve of the invention controls a fluid moving in a valve body by closing and opening a portion between a valve seat and a valve holder by use of a drive unit. The drive unit has a rod-shaped shaft for application of pressure through the valve seat and the valve holder, and a member “a” fixed around the rod-shaped shaft. The member “a” is made from a magnetic material, and has a space between it and the shaft. A coil provided in parallel to the shaft, moves the shaft via the member “a” up and down by electromagnetic induction, and makes use of a spring force to close and open a portion between the valve seat and the valve holder.

    摘要： A tightening device comprises an upper plate, a lower plate disposed below the upper plate in parallel thereto, a nut rotating gear supported by the lower plate so as to be rotatable in a horizontal plane, and a spur gear provided on an underside of the upper plate and meshable with the nut rotating gear for rotating the nut rotating gear. The upper plate has a portion fittable to a flange of an externally threaded member for preventing the rotation of the threaded member, while the nut rotating gear has a portion fittable to a nut. With the nut manually tightened on the threaded member in advance, the flange fitting portion of the upper plate is fitted to the flange, the nut is fitted in the fitting portion of the nut rotating gear, and the spur gear is thereafter rotated, whereby the nut rotating gear is driven to tighten up the nut on the threaded member.
