摘要： PROBLEM TO BE SOLVED: To improve a dust raking up function by providing the front part of a sucking appliance main body with a first ventilator and the rear part with a second ventilator, respectively to introduce external air in the direction of the suction port opening at a bottom surface. SOLUTION: The sucking appliance main body 1 is moved along a floor surface 15 constituting of a carpet, e.g. to suck by the vacuum cleaner main body. Surrounding air is sucked with dust on the floor surface 15 from the sucking port 9 by this appliance. At the same time, external air is sucked from the first and second ventilators 12 and 13. A ventilated air stream (a) from the first ventilator 12 flows out to the front side of a sucking passage from a first downstream opening part 12b to move in the direction of the sucking passage. A ventilated air stream (b) from the second ventilator 13 flows out to the front side of a sucking passage from a downstream opening part 13b to move in the direction of the sucking passage. Both of the air (a) and (b) collide with the floor surface 15 to show the dust raking up function. By this raking up, dust is effectively sucked.

摘要： PROBLEM TO BE SOLVED: To prevent the mouth part of a ventilating path blowing air from being clogged with the fur of a carpet at the suction tool for a vacuum cleaner raking up dust by blowing air to a floor surface. SOLUTION: A bumper 18 made of a soft material is arranged at the outer peripheral part of a suction tool main body 1, a ventilating path 19 made of the soft material in one body with the bumper 18 is formed at the bumper 18 on the front side of the main body 1 to be vertical to a floor surface. By the sucking operation of a cleaner main body, peripheral air is sucked also from the path 19 to collide with the floor surface to rake up dust. Then the mouth part of the path 19 is deformed in the advancing direction and in the opposite direction by the moving forward/backward of the main body 1.

摘要： PROBLEM TO BE SOLVED: To efficiently suck dust even in a wall edge and a corner part. SOLUTION: When a suction tool main body 1 is mounted on a surface to be cleaned and a vacuum cleaner is driven, an air passing through a ventilation path 7 is collided with the surface to be cleaned so that the dust is raked up to be sucked into a suction port 5 and sucked into the cleaner main body. When the front surface of the suction port main body 1 is brought in contact with a wall or a furniture, the opening 7a of the ventilation path 7 is blocked so that the collision wind in the arrow (a) direction is shut off. The blockage of the opening 7a increases the wind quantity in the arrow (b) direction and the air flowing from the front face of the suction tool main body 1 to the opening part is increased so that the dust in the wall edge and the corner part is sucked.

摘要： PROBLEM TO BE SOLVED: To improve a dust raking-up function by respectively providing a sucking space part provided with a suction port at a bottom surface, communicated with a communicated pipe and incorporating a rotary blade and introducing external air from a ventilator provided through the front surface of a suction appliance main body. SOLUTION: The sucking appliance main body 1 is moved along a floor surface 16 to suck by the vacuum cleaner main body. Surrounding air is sucked with dust on the floor surface 16 from the sucking port 9 thereby. At the same time, ventilated air stream (a) is sucked also from first ventilator 12 to introduce to the direction of a suction passage. The rotary blade 13 is rotated to generate a rotary descending stream (b). This stream (b) collides with the stream (a) to prevent the stream (a) from raising to press to the floor surface 16 to collide. Then, dust on the surface 16 is raked up to effectively collect dust.

摘要： PROBLEM TO BE SOLVED: To provide a heat sink, having high heat transfer rate on the backs of projections formed, in order to increase the heat transmission area and thereby having high cooling capacity.
SOLUTION: The heat sink 2 is provided with a base 4 having a first face 4a, thermally connected to a heating element 3 and projections 6 formed on a second face 4b, which is located on a side of the base 4 opposite to the first face 4a and constitutes a part of a cooling medium passage. An inclined face 6a, having an attack angle with respect to the main flow of the cooling medium is formed on each projection 6. The inclined face 6a is formed so that an intersecting line with an XZ plane rectangular to the cooling medium main flow direction (Y direction) makes an acute angle with the normal direction (Z direction) of the second face 4b. Since the inclined face 6a is formed, in a state inclined from the second face 4b on a position observed from the cooling medium main flow direction, a pair of asymmetrical vertical eddies, having respectively different turning radii, are generated. Thereby, a stagnation region on the back side of the projection 6 is reduced, due to the vertical eddies having large rotational radii and heat transfer rate on the back of the projection can be improved.
