A hopper for cleaning a coating machine in which a rotary atomizing head extends through an opening in the upper surface of a hopper housing, a thinner for cleaning the rotary atomizing coating machine and a residual coating material are sprayed on the inside, an airstream control member for preventing flow from ascending from the inside of the housing to the outside of the housing through a gap between the coating machine and the opening by the rotation of the rotary atomizing head corresponding to the gap between the coating machine and the opening, and the control member is formed with an air vent hole for supplying air to a negative pressure zone formed just below the rotary atomizing head.
摘要:
Upward whirling of a coating material through a gap between a coating machine and an opening is prevented without using a shaping air upon cleaning a coating machine in a cleaning hopper by supplying a thinner to the coating machine and rotating a rotary atomizing head at a high speed.To the inside of a hopper (1) used for cleaning a coating machine in which a rotary atomizing head (B) is entered through an opening (3) formed to the upper surface of a hopper housing (2) upon supplying a thinner for cleaning to the rotary atomizing coating machine (T) and a residual coating material and a thinner are sprayed to the inside thereof, an airstream control member for shutting a flow ascending from the inside of the housing to the outside of the housing passing through a gap between the coating machine and the opening by the rotation of the rotary atomizing head is disposed so as to situate below the rotary atomizing head corresponding to the gap between the coating machine and the opening, and the control member is formed with an air vent hole for supplying air to a negative pressure zone formed just below the rotary atomizing head.

A paint filling apparatus has a plurality of header portions, and one common manifold portion that is capable of supplying a cleaning liquid to each header portion. One side of each header portion is attachable to and detachable from a paint cartridge, and another side of each header portion is attachable to and detachable from the common manifold portion. Each header portion has a paint supply channel for filling a paint into the paint cartridge. The paint supply channel of each header portion is constructed of a piping member and a paint channel. An end portion of each header portion is linkable in communication with the inside of the paint cartridge, and another end portion thereof is linked in communication with a corresponding one of paint tanks that are provided separately for each of the paint colors. An intermediate portion of each paint supply channel is provided with a paint valve that controls the open-closed state of the upstream side of the paint supply channel.

The present invention provides oxygen concentrators which achieve reliable pressure control in the oxygen columns with reduced number of components for pressure control in the oxygen columns, and also easy maintenance and reduced power consumption. PSA, PVSA, or VSA oxygen concentrator consisting of oxygen concentration columns BF1 and BF2, pressure control means for adjusting pressure in the oxygen concentration columns, and oxygen tank T for storing concentrated oxygen, comprises mechanical flow control means SC1 which regulates flow from the oxygen tank to the oxygen concentration columns. Pressures in the oxygen concentration columns BF1 and BF2 are kept within a predetermined range by the function of mechanical flow control means SC1 placed in between the oxygen concentration columns and the oxygen tank.

A painting material charging device may comprise a cartridge attaching unit, a painting material supplying path, a first switching unit, a painting material supplying unit, a discharging path, a second switching unit, a painting material sensor and a controlling unit. The controlling unit may be configured to be connected to the painting material sensor and the second switching unit. The controlling unit may be configured to cause the second switching unit to fully close the discharging path in a case where the painting material sensor detects the painting material.

There is provided a structure (17) for preventing electrical leakage for use in an electric power tool, typically a grinder (1), encased in a split aluminum housing (2, 3, 4) and provided with a commutator motor (5), a pair of brush holders (12) each including a brush (13) pressed against the commutator (6a) of the motor, and a fan (8) driven by rotation of the commutator motor for drawing air from the outside of the electric power tool through a plurality of air inlets (9) formed in the housing. The split housing includes a removable rear cover (4) that can be detachably fitted on the grinder. The structure is a shield (17) that is provided between the brush holders and the air inlets, for blocking air drawn by the fan from the air inlets to the brush holders. The shield is a substantially symmetrical element which includes a center portion (18) clamped between the removable part and the fixed part of the housing having two side edges, a pair of arm portions (19) extending outward from the side edges of the center portion, and a pair of cover portions (20) connected to the arm portions such that the cover portions are positioned close to the brush holders to block air drawn by the fan from the air inlets to the brush holders.

An atomizing apparatus comprises a body having a chamber into which liquid is supplied. A nozzle member is secured to the body to define a front vibrating member of said of the chamber, the nozzle member having at least one nozzle opening. A capacitive piezoelectric transducer is secured to the nozzle member for producing pressure rises in the liquid to cause the portion of the liquid in proximity to the nozzle opening to be ejected therethrough to the outside. The piezoelectric transducer is connected to an inductance element to form a resonant circuit. An amplifier is connected with the resonant circuit to form a self-oscillating loop to amplify the signal in the loop to sustain oscillation at a frequency variable as a function of the temperature-dependent capacitance of the piezoelectric transducer.

A paint supply method supplies a paint into a paint cartridge by using a filling valve that has: a paint supply channel that is linkable in communication with a supply portion provided for supplying the paint into the paint cartridge; a branch channel that branches from the paint supply channel near a site of linkage in communication between the supply portion and the paint supply channel; and a trigger valve as an open-close valve of the paint supply channel which is disposed in the paint supply channel upstream of the site of linkage in communication. After a filling liquid is filled into the branch channel, the trigger valve (open-close valve) is opened, and the paint is supplied into the paint cartridge via the paint supply channel.
