Abstract: A compressed gas supply unit has scroll compressors. Gas discharged from the scroll compressors travels through a main supply passage and is reserved in a reservoir tank, after which the gas is supplied to a gas recipient from a supply passage. The scroll compressors include inverter devices that allow for independent modulation of the speeds of respective drive motors. The controller includes a speed range setting unit that sets an upper speed limit and a lower speed limit of the scroll compressors, a speed sum calculating unit that calculates a sum of speeds of the scroll compressors based on a load of the compressed gas supply unit, and a speed setting unit that allocates the calculated sum of speeds among the scroll compressors to set speeds for scroll compressors respectively.

Abstract: Provided is a double rotation type scroll expander, aiming at protecting a bearing that supports drive shaft a drive shaft and the like from the heat of a working medium when a working medium introduction hole is provided in the drive shaft. The working medium introduction hole is drilled into the drive shaft such that the high-temperature, high-pressure working medium is supplied to expansion chambers through the working medium introduction hole. An adiabatic sleeve that forms a part of the working medium introduction hole is attached to the drive shaft in an internal region of roller bearings that support the drive shaft and a driven scroll body rotatably. Heat transfer from the working medium to the roller bearings is suppressed by the adiabatic sleeve, whereby the roller bearings are prevented from deteriorating.

Abstract: The electrostatic spray device includes a liquid sprayer including a nozzle that spouts a liquid; a voltage applicator that applies a voltage between the liquid sprayer and a heteropolar portion functioning as a pole opposite a pole of the liquid sprayer to generate an electrostatic force for causing the liquid to separate from a distal end of the nozzle in a charging state; and a stabilization electrode that maintains a stable spraying state of the liquid even when a pressure is applied to the liquid to supply the nozzle with the liquid. The stabilization electrode has an electric potential identical to an electric potential of the liquid sprayer, and is disposed near the nozzle such that a jet portion formed at a front of the nozzle by a linear extension of the liquid has a length longer than a length of the jet portion before the stabilization electrode is provided.

Abstract: An electrostatic spray device including a voltage applicator and an isoelectric line adjustment electrode. The voltage applicator applies a voltage between a liquid sprayer and a heteropolar portion functioning as a pole opposite from a pole of the liquid sprayer to generate an electrostatic force. The isoelectric line adjustment electrode is made from a conductive material and adjusts equipotential curves appearing so as to surround the nozzle. The isoelectric line adjustment electrode obtains the equipotential curves at least partially drawing curvature gentler than curves of equipotential curves appearing near a front side of the nozzle in a state where the isoelectric line adjustment electrode is not disposed. The isoelectric line adjustment electrode is located near an outer periphery at a distal end of the nozzle and has an electric potential identical to an electric potential of the liquid sprayer such that the equipotential curves drawing the gentle curvature are obtained.

Abstract: A spray gun having a body formed of a front end, a middle, and a rear end, a gas cap attached to the front end, and a needle that opens/closes a liquid nozzle attached to the middle. The front end has a through-hole extending from a front side, on which the gas cap is disposed, toward the middle. The middle includes a protrusion in the through-hole of the front end and a through-hole leading to a liquid supply port formed in the middle and extending from a front end side through the protrusion toward the rear end. The liquid nozzle is in the through-hole of the protrusion. The needle extends from a rear end side through the through-hole of the middle so that a distal end of the needle is in a distal opening of the liquid nozzle in an insertable/removable manner.
