Abstract:
A solution for removing an aluminum oxide film from an aluminum or aluminum alloy surface, which includes a salt or oxide of a metal capable of substituting aluminum, a solubilizing agent for ions of the metal, and an alkali, and which has a pH of 10 to 13.5. The removing solution makes it possible to form a film of the metal derived from the metal salt or oxide contained in the removing solution by dissolving away the oxide film from the aluminum or aluminum alloy surface at a low temperature and a high speed while restraining, as securely as possible, erosion of the aluminum or aluminum alloy surface. The removing solution ensures that even in the case where the thickness of the aluminum or aluminum alloy basis material is very small, the aluminum or aluminum alloy surface can be activated while assuredly leaving the aluminum or aluminum alloy basis material.
Abstract:
An optical coherence tomographic apparatus includes a unit configured to perform tracking of an eye to be examined based on a plurality of images of the eye which are obtained at different times, and a control unit configured to control the unit which performs the tracking in a case where a plurality of tomographic images of the eye are obtained.
Abstract:
A power tool (1) and a method of producing such power tool capable of improving dust proof performance with respect to a circuit board (33) and a stator coil (31B), and capable of securing cooling performance to the circuit board. The power tool includes a brushless motor (3) having a hollow stator (31), a rotor (32) positioned in an internal space of the stator, and a motor driver circuit connected to the stator. The stator includes a coil (31B) electrically connected to the mo- for driver circuit. The coil is coated with a coating agent (31D), and the motor driver circuit is covered with an insulation cover member (33D).

Abstract:
When an anterior segment photographing mode is selected, ease of operation by an inspector is improved. An ophthalmologic apparatus includes an area changing unit for changing a movement area of an optical unit including an optical path of measuring light, when an anterior segment photographing mode for photographing an anterior segment of an eye to be inspected is selected, to be different from a movement area when a mode other than the anterior segment photographing mode is selected.
Abstract:
An electric power tool (1) includes a brushless direct-current motor (3) and a drive circuit that supplies drive power to the motor, the power tool rotates or drives a tool, whereby the drive circuit includes plural switching elements (21), and is arranged on a board (9) provided in a grip portion of a housing or below the grip portion; and an electric fan (22) is provided in the vicinity of the switching element for cooling the switching element.
Abstract:
A medical imaging apparatus includes an imaging unit configured to capture an image of a subject, an imaging sequence registration unit configured to register an imaging sequence, and a display unit configured to display the imaging sequence registered by the imaging sequence registration unit.
Abstract:
A portable electrical tool includes a tip tool; a cylindrical housing accommodating a motor including a chuck attachably and detachably holding the tip tool at tip end of a rotation shaft; a base including a surface plate which slides on an upper surface of work material, and which allows the tip tool to protrude from the surface plate downwardly, a cylindrical portion including a cutout portion, and a lever having a cam surface, and rotatable to a fixed position and a release position. When the lever is in the fixed position, a gap at the cutout portion is narrowed to stop movement of the cylindrical housing. When the lever is in the release position, the cylindrical housing is movable by weight in the cylindrical portion. The tool includes a stopper to stop a rotation of the lever between the fixed position and the release position.
Abstract:
A cooling structure for electronic equipment is designed for cooling a heat-generating body (2a) disposed inside a case (20) by recovering heat generated by the heat-generating body (2a) and dissipating the heat to the outside of the case (20). The cooling structure includes a heat-receiving section (4) for recovering heat generated in the heat-generating body (2a), a thermally insulated space (6) provided with an air inflow orifice (42a) and an air outflow orifice (42b) and thermally insulated from the heat-generating body (2a) and heat-receiving section (4) by a thermally insulating member (40), a heat-dissipating section (7) provided inside the thermally insulated space (6), a heat transfer member (5) for transferring the heat recovered in the heat-receiving section (4) to the heat-dissipating section (7), and a fan (22) for generating forcibly an air flow in the thermally insulated space (6). The heat generated by the heat-generating body (2a) is transferred to the heat-dissipating section (7) via the heat-receiving section (4) and heat transfer member (5) and dissipated in a concentrated fashion by using the fan (22) inside the thermally insulated space (6).
Abstract:
