Patent application number	Description	Published
20110188958	CUTTING METHOD - There is provided a cutting method for cutting a work by rotating a rotary tool with a circular cutting edge around an axis while a cutting fluid is supplied thereto. Cutting is performed by means of the rotary tool which is rotated in the same rotational direction as an outflow direction of chips, and the rotary tool is rotated at a rotational speed of the rotary tool at which a circumferential speed of the cutting edge is higher than an outflow speed of the chips. Thus, the area of direct solid contact between the rotary tool and the chips is reduced with the aid of a dynamic pressure effect, and the abrasion of the rotary tool is suppressed.	08-04-2011

20100207625	CURRENT SENSOR - A current sensor includes an annular magnetic core that includes a closed magnetic path including a void in a portion thereof, and a magnetic body for focusing flux of a magnetic field generated around a conductor that carries a measured current, and a magnetic detecting portion for detecting flux of a magnetic field generated in the void of the magnetic core. The magnetic core includes a plurality of pairs of stepped portions on a pair of opposing end surfaces that form the void, the stepped portions descending along a direction separating from the conductor.	08-19-2010

20080263889	Hand Drying Apparatus - In a hand drying apparatus, an infrared light absorber absorbs infrared light, when a hand is not present, emitted from an infrared light emitter provided on an inner surface of a drying space.	10-30-2008
20080273866	Hand dryer apparatus - A hand inserting portion is opened at one surface of a casing or at both the one surface and other surface of the casing. The hand inserting portion includes a space in which hands can be accommodated. A high-pressure-airstream generating unit generates a high-speed airstream. A nozzle is provided on each of two opposing sides of the hand inserting portion, from which the high-speed airstream is jetted into the space of the hand inserting portion. The nozzle includes a hole array formed by arranging a plurality of nozzle holes in a row. Air volume of the high-speed airstream is larger at a central portion of the hole array than at other portions of the hole array.	11-06-2008
20090154907	Hand dryer apparatus - A hand inserting portion is opened at one surface of a casing or at both the one surface and other surface of the casing. The hand inserting portion includes a space in which hands can be accommodated. A high-pressure-airstream generating unit generates a high-speed airstream. A nozzle is provided on each of two opposing sides of the hand inserting portion, from which the high-speed airstream is jetted into the space of the hand inserting portion. The nozzle includes a hole array formed by arranging a plurality of nozzle holes in a row. Air volume of the high-speed airstream is larger at a central portion of the hole array than at other portions of the hole array.	06-18-2009
20100192399	HAND DRYING APPARATUS - A hand drying apparatus includes a high-pressure airflow generator that takes air through an air inlet and generates a high-pressure airflow, a main body casing, a first air path that is protruded from the main body casing, and a nozzle that is located in a position ahead of the main body casing in a direction of the first air path. The main body casing includes a main-body air inlet through which outside air is taken and a second air path that causes air from the main-body air inlet to flow upward and then downward to a level where the air inlet of the high-pressure airflow generator is located.	08-05-2010
