Title: Ball end mill
Inventor: SASAKI KAZUYOSHI
IPC: B23C5/10
Filed: 1991-10-03
Abstract: PURPOSE:To provide favourable sharpness and a long life by making a ball part cutting blade as a right blade torsional to left or a left blade torsional to right and gradually changing the rake angle of the ball part cutting blade toward the ball head end part. CONSTITUTION:A cutting blade 3 is made as a right blade torsional to left, and an outer peripheral blade shaft rectangular section is formed in an orthohexagonal shape. That is, an outer peripheral blade rake angle gammar is to be -60 deg., and furthermore, the rake angle gammar of a ball part cutting blade 3 is sequentially changed and the rake angle gammar of the last head end part is set as O deg.. Consequently, cutting is to be started from the outer peripheral blade side which is favourable in sharpness and large in rigidity, and the cutting is stabilized. Additionally, the cutting amount comes to be smaller toward the ball head end part, sharpness comes to be more favourable as the blade edge comes to be sharper due to change of the rake angle gammar, and wearing in the neighbourhood of the ball head end part is restrained. Additionally, as the cutting blade rake angle is set as a negative value of 0 deg. to -60 deg. blade edge strength is heightened, chipping and others are prevented and the cutting comes to be favourable.

Title: Surface defect flaw detecting device
Inventor: HIWASA ATSUSHI
IPC: G01N21/89
Filed: 1985-12-17
Abstract: PURPOSE:To execute a flaw detection with a roughly uniform sensitivity with respect to the surface of the material, of a column or its similar shape to be inspected, by detecting an infrared-ray radiated from the surface of the material to be inspected, by plural pieces of infrared-ray detectors placed concentrically against the center of the material to be inspected. CONSTITUTION:A material to be inspected 1 whose surface is heated by a high frequency power source 2a and an induction heating coil 2b is carried and enters into the visual field of infrared ray detectors 3a1-3an. In this state, a current conducting to the surface of the material to be inspected 1 is usually concentrated in depth of <=1mm under the surface by a skin effect, therefore, in a surface defect part, its current path becomes longer than that of a part where there is no defect, the heating density increases and a temperature becomes high. On the other hand, before the material to be inspected 1 is carried and enters into the visual field of the infrared ray detectors 3a1-3an, the heat of the surface is diffused, but as for the surface defect part, the efficiency of heat conduction and heat radiation is worse than that of the part where there is no defect, therefore, a high temperature state is maintained. Accordingly, a defective part can be detected by being discriminated from the part where there is no defect.

Title: Protecting method for hydraulic iron pipe during inoperation of pressure regulator
Inventor: KAWAKAMI KAZUMI
IPC: F03B15/18
Filed: 1985-12-17
Abstract: PURPOSE:To reliably prevent increase of a water pressure in a hydraulic iron pipe, by a method wherein, when a pressure regulator, adapted to prevent increase of a water pressure in a hydraulic iron pipe, is inoperative, a flow rate equivalent to a flow rate throttled by the runner vane of a water turbine is discharged by opening the guide vanes of a water turbine. CONSTITUTION:A pressure regulator 5, adapted to prevent increase of a water pressure in a hydraulic iron pipe 1, is mounted to a water turbine casing casing 2, and is controlled by a hydraulic type controller 6. When guide vanes 3 are opened and closed at a speed, for example, lower than the set value of a dash pot, the pressure regulator 5 is closed. In the above constitution, when the pressure regulator 5 is inoperative, a flow rate equivalent to a flow rate throttled by a runner vane 4 of a water turbine is discharged with the guide vanes 3 of the water turbine opened. This constitution prevents increase of a water pressure in the hydraulic iron pipe 1 to prevent damage of the hydraulic iron pipe 1, and reduces production of a change in a flow rate in the hydraulic iron pipe 1.
