摘要:
An exhaust gas filter comprises an outer tube, a plurality of center-closing filter units each having an isolation plate; and a plurality of center-opening filter units having an annular isolation plate, two kinds of filter units being arranged alternately in the outer tube. The isolation plate and annular isolation plate are enclosed by flammable fibers. When a contaminated gas goes through the flammable fibers, it can be filtrated.

A sealing device includes a stationary member, an orbiting member, a tip end surface of which slides on an inner face of the stationary member, and a sealing member to be fitted into a sealing groove engraved on the tip end surface. A sliding contact surface of the sealing member is pressed onto an inner surface of the stationary member with a predetermined force to slide on the inner surface in order that fluid sealing is secured between the sliding contact surface of the sealing member and the inner surface of the stationary member. The sealing member is divided into two parts of an upper ring and a lower ring, with the upper ring contacting the sliding contact surface and the lower ring facing a bottom surface of the sealing groove.

A resonator of an acoustic compressor is provided at each side of an actuator so that the two resonators are arranged side by side. Two pistons are provided at the inner ends of the resonators and actuated by the actuator. At the outer end of the each of the resonators, a gas is introduced into the resonator through a suction hole. When the pistons are actuated by the actuator, the gases in the two resonators are oscillated and compressed by the piston and discharged through discharge holes at the outer ends of the resonators.

A scroll fluid machine comprises a fixed scroll, an orbiting scroll and a plurality of self-rotation preventing device for preventing the orbiting scroll from rotating on its own axis. On the rear surface of the orbiting scroll, a reinforcement bearing plate is fixed with a central bolt and an outer circumferential bolt. A follower of the self-rotation preventing device is provided in the reinforcement bearing plate. An oil-supply hole is formed through the reinforcement bearing plate to supply oil to the follower.

Air is introduced from an intake chamber into a plurality of hollow fiber membranes in a casing. The casing is connected to a vacuum pump via a three-way valve and water vapor in air is evacuated through the membranes. Dehumidified or dried air is discharged from a discharge chamber at the ends of the membranes. The vacuum pump is connected to a detector/selector. If the vacuum pump is out of order, it is detected by the detector/selector and another dehumidifier including a depressurizing device is actuated.

In a scroll fluid machine, an orbiting scroll is revolved with respect to a fixed scroll in a housing. A self-rotation-preventing device is provided to prevent the orbiting scroll from rotating on its own axis. The device comprises a pair of holders, one of which is disposed in an orbiting side and the other is disposed in the housing. The holder in the orbiting side comprises a bearing, a holding plate for holding the bearing and a plurality of ears. At least one of the ears is disposed within a circle passing through the centers of the holders around the center of the orbiting scroll.
摘要:
An operation control devices and operation methods thereof so as to eliminates the difficulties in such a case of introduction of vacuum sensors and/or inverter control is disclosed. The disclosure relates to a control of plural sets of vacuum pumps. In order to comply with the subjects to overcome the difficulties, the disclosure proposes to utilize current detection approach instead of direct pressure detection approach, while showing how to estimate a vacuum degree achieved under the operation of the pumps as well as presenting a method on the control of the number of pumps. It is also described how organically a current detecting device, a vacuum degree estimating device, a working pump control device and related methods to satisfy the subjects are linked. The usefulness of the disclosure is also revealed.
摘要:
There is provided an attachment for an air spray gun, to be connected to the bottom of a grip of the spray gun. It includes a control valve to adjust the air flow rate, a gun coupling disposed in the body of the control valve to communicate with an outlet-side passage and thus connect to the spray gun, and a rotary joint having a hose coupling fixed thereto and which is to be fitted rotatably into an inlet-side passage to allow the hose coupling to communicate with the inlet-side passage. The hose coupling is freely turned in relation to the gun coupling fixed to the spray gun for the angle formed between them to freely be variable. A pressure gauge is installed on the attachment to communicate with the outlet-side passage and indicate the pressure of air supplied through the passage. The display surface of the pressure gauge forms an obtuse angle in relation to the axis of the gun coupling.
