| 20120103850 | PAINT CARTRIDGE - A paint cartridge ( | 05-03-2012 |
| 20110271906 | ELECTROSTATIC COATING APPARATUS - A rotary atomizing head is mounted on a fore end side of a motor. A shaping air ring having a plurality of air outlet holes at fixed intervals is provided on a rear side of the rotary atomizing head. Outer surfaces of the air motor and outer surfaces of the shaping air ring are enshrouded over the entire circumference by a cover member formed of an electrically insulating material. An external electrode assembly is provided radially outwardly of the cover member. An annular projecting portion which projects forward is provided on the shaping air ring over the entire circumference. The air outlet holes are open in a fore distal end of this annular projecting portion. As a result, a corona discharge can be generated by allowing an electric field to be concentrated at the fore distal end of the annular protecting portion. | 11-10-2011 |
| 20110107966 | ELECTROSTATIC COATING APPARATUS - A current sensor for detecting a full return current is connected to a high voltage generator. A leakage current detector including current sensors for detecting a leakage current is provided at the surface of the cover of a coating machine, air passages and a paint passage. Based on current detection values obtained by the current sensors, a high voltage control unit controls a power supply voltage control unit and a high voltage to be output from the high voltage generator can be raised or dropped. By employing the current detection values, the high voltage control unit can identify and provide notification of a location where the leakage current is increased and the insulation is deteriorated, and can request an operator to perform maintenance for the pertinent location. Further, upon occurrence of the insulation being deteriorated, the high voltage control unit can stop the high voltage supply. | 05-12-2011 |
| 20100282865 | ROTARY ATOMIZING HEAD TYPE COATING DEVICE - A rotation restricting mechanism is provided between a mounting shaft section of a rotational shaft and a mounting tube section of a rotary atomizing head. The rotation restricting mechanism includes a male spline member provided on the outer peripheral side of the mounting shaft section, and a female spline member provided on the inner peripheral side of the mounting tube section. By meshing engagement of the male spline member with the female spline member, the rotation restricting mechanism restricts rotational displacements of the rotary atomizing head relative to the rotational shaft. | 11-11-2010 |
| 20100243101 | PAINT REPLENISHING SYSTEM FOR CARTRIDGE - A quantitation setup mechanism ( | 09-30-2010 |
| 20100230511 | PAINT COATING SYSTEM - A common body ( | 09-16-2010 |
| 20100206225 | ELECTROSTATIC COATING APPARATUS - An atomizer ( | 08-19-2010 |
| 20100193613 | ELECTROSTATIC COATING APPARATUS - A housing member includes a main housing body and an intermediate tube provided around the outer periphery of the main housing body. Located in a front portion of the main housing body is an atomizer including an air motor and a rotary atomizing head, while located in a rear portion of the main housing body is a high voltage generator to apply a high voltage to paint through the air motor. A multitude of hollow cavities are uniformly formed in the intermediate tube over the entire outer surface thereof by the use of through holes opened through the intermediate tube. A cover member is fitted on the outer surface of the intermediate tube in contact with the intermediate tube, thereby intensifying electric field strength in outer corner portions of the hollow cavities to prevent deposition of charged paint particles. | 08-05-2010 |
| 20100001099 | AIR ATOMIZING TYPE COATING APPARATUS - There is provided an air atomizing type coating apparatus which is constituted by a main body ( | 01-07-2010 |
| 20090277378 | COATING APPARATUS - A round outer periphery of a valve mount member ( | 11-12-2009 |

| 20090206177 | PAINT APPLICATION CARTRIDGE - A tank base ( | 08-20-2009 |
| 20090071397 | ROTARY ATOMIZER HEAD TYPE PAINING MACHINE - A coupling portion is provided on an outer peripheral side of a rotational shaft, a stationary ring is mounted on a fore end portion of an air motor, a rotatable ring is rotatably attached to a stationary ring, and slide plates are provided between the stationary ring and the rotatable ring movably in radially inward and outward directions of the rotational shaft. A slider shift mechanism provided on the stationary ring and the rotatable ring brings each slide plate into and out of engagement with the coupling portions in step with a rotational movement of the rotatable ring. Thus, for locking the rotational shaft in a fixed state, an operator grips and turns the rotatable ring with one hand to engage the slide plates with the coupling portions by the slider shift mechanism. In this state, a rotary atomizing head can be mounted on or dismantled from the rotational shaft. | 03-19-2009 |
| 20090032625 | ELECTROSTATIC COATING DEVICE - An atomizer including an air motor and a rotary atomizing head, mounted in a front side of a housing member, while a high voltage generator applying a high voltage to paint through the air motor is mounted in a rear side of the housing member. A cover member is fitted on the housing member to cover an outer surface of the housing member. Opposite axial ends of the cover member are fitted on and attached to opposite axial ends of the housing member so as to leave an annular gap space between the cover member and the housing member. The annular gap space keeps almost entire radially confront areas of the cover member and the housing member, preventing high voltage electrostatic charges on the outer surfaces of the cover member from leaking through the housing member. | 02-05-2009 |
| 20090026293 | ELECTROSTATIC COATING DEVICE - An atomizer ( | 01-29-2009 |
| 20090020635 | ROTARY ATOMIZING-HEAD TYPE COATING MACHINE - A rotary atomizing-head type coating machine, wherein a paint passage for flowing a paint to a rotary atomizing-head, a turbine air passage flowing a turbine air to the turbine of an air motor, a discharge air passage for flowing the turbine air after driving the turbine to the outside in the form of a discharge air, and a heat insulating air discharge passage of a heat insulated air passage axially extending while surrounding the discharge air passage and allowing hot heat insulated air to flow therein are formed in the bottom part of a housing body forming a housing. Thus, even if the turbine air expanded in a heat insulated state and reduced in temperature flows in the discharge air passage, the housing can be prevented from being cooled by the discharge air by flowing a heat insulated air with a temperature higher than that of the discharge air in the heat insulated air discharge passage. | 01-22-2009 |
