Title: Axial flow fan
Inventor: KAI TORU
IPC: F04D29/38
Filed: 1991-11-18
Abstract: PURPOSE:To prevent noise caused by turnbulence of flow when air flows in a blade end part by providing a semi-circular thick wall part on a part or the whole part of the positive pressure surface of respective outer circumferencial rims in a plurality of blades provided on a hub outer circumference, in an axial flow fan used for a ventilating air blower or the like. CONSTITUTION:An axial fan is provided with a propeller fan in which a plurality of blades 101 are installed on the circumrerence of a hub and the propeller fan is arranged in an annular shaped ventilation port 104 having a bell mouse shaped part and a straight pipe part while maintaining a prescribed clearance in circumferencial direction. In this case, a semi-circular thick wall part 1 is provided on the positive pressure surface 108 of an outer circumferencial rim on each blade 101. As a result, when the propeller fan makes its rotational motion, flow (d) followed by turbulence and flowing in the positive pressure surface 108 is forced to flow along the thick wall part 1 regardless of its flow-in direction so as to reduce generation of vortex. It is thus attempted to reduce noise generated by vortex.

Title: Rotary drilling tool
Inventor: TSUNASHIMA TERUTOSHI
IPC: B23B51/00
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To provide the drill structure, which can restrict the deficiency of a central part of rotation of the drill and which allows the drill to be manufactured inexpensively, by providing a cutting blade up to the central part of rotation or its vicinity of a tip end part of a tool main body of a rotary drilling tool. SOLUTION: A body 12 of a drill 10 is formed with a hard and highly ductile material, and two rows of flutes 13 are prepared. Outside a domain bounded by a prescribed radius from the center of the tip end part of the body 13, blading tips 14 made of such a material as is harder and more wear-resisting than the hard and highly ductile material forming the body 12 are fixed by brazing on the rear (with rotation) side of both flutes 13, while cutting blades 12 made of hard and highly ductile material are formed within a domain having a prescribed radius. As a result, the drilling resistance of the drill 10 can be made small. In addition, since the cutting blade having a high ductility is formed in the central part of rotation, chips hardly catch or stick to the drill 10.  Moreover, since the hard and highly ductile material for the body (12) itself is used as the material for the blade edge at the central part of rotation, precise and complicated machining can be dispensed with. Therefore, even in the case of a tool having a relatively small diameter, the tool can be manufactured easily.
