Title: Taper end mill
Inventor: YAMAZAKI TAKAFUMI
IPC: B23C5/10
Filed: 1989-12-28
Abstract: PURPOSE:To enable prolongation of an axis of a taper end mill and secure the sharp ness by forming a web thickness radial dimension of the tip into the specified times of an outer radial dimension of the same part, and forming a rake angle in the radial direction of a cutting blade into 0 deg. or a positive angle, and forming an angle of a web thickness taper equal to a taper angle of an outer radial dimension of the a cutting blade. CONSTITUTION:In an end mill having a taper blade of which twisting angle is constant at any position of a cutting blade 1, a web thickness radial dimension d0 of the tip is formed into more than 0.7 times of an outer radial dimension D0 of the tip and less than 0.9 time thereof, and a rake angle alpha in the radial direction of the cutting blade 1 is formed into 0 deg. or a positive angle, and a web thickness taper angle theta1 is made equal to an outer radial taper angle of the blade. The tool rigidity is therefore made equal to that of a taper end mill having cross sectional polygon or more than that to have the excellent sharpness. A chip pocket is formed just under the cutting blade to improve the chip exhausting property more than that of the taper end mill having a cross sectional polygon. Consequently, in a taper end mill for processing the steel material and the pre-hardened steel, the tool rigidity is improved to enable prolongation of an axis, and the required sharpness can be secured, and the processing accuracy of a deep taper channel can be improved sufficiently.

Title: Painting spray gun
Inventor: YOSHIDA OSAMU
IPC: B05B5/025
Filed: 1994-12-27
Abstract: PURPOSE:To prevent potential difference occurrence due to high voltage in a seat part even if a paint to be sprayed out of a paint spraying outlet is stopped under a condition that high voltage is applied to a needle--like electrode. CONSTITUTION:A conductive layer 23 of a conductive ceramic is formed in a valve part 21A installed in the tip side of a needle valve body 21. Consequently, since the residual paint TB charged at high voltage by a needle-like electrode 22 and the residual paint TA connected to an earth side are electrically communicated to each other by the conductive layer 23, potential difference occurrence due to the high voltage VH between a valve seat 5E of a paint nozzle 5 and the conductive layer 23 of the needle valve body 21 is prevented at the time of closing the valve of a paint spraying outlet 5D. Electrolytic corrosion occurrence on the surface of the valve part 21A of the needle valve body 21 is thus prevented and the life of the needle valve part 21 is extended.

Title: Film feeding controller for camera
Inventor: KAZAMI KAZUYUKI
IPC: G03B17/00
Filed: 1989-12-28
Abstract: PURPOSE:To accomplish the alignment of image planes after reloading a film which is taken out midway by using a Hall element as a means for detecting information magnetically recorded on the film, detecting the exposed image plane according to whether magnetic information is recorded or not by using an electromagnet or a permanent magnet as an information recording means and controlling the feeding of the film based on the detected result. CONSTITUTION:The discrimination between a photographed image plane and an unexposed part is executed by assuming that it is performed according to the presence or absence of the magnetic information on the film. Then, the inexpensive Hall element is used as a detection means for the magnetic information and the electromagnet or the permanent magnet which is inexpensive and has simple constitution is used as a recording means 2 for the information. In the case of feeding the film by a film feeding means 4, a control means 1 acts so that the information may be magnetically recorded on the film by the information recording means 2 and controls the film feeding means 4 with the output of a recorded information reproducing means 3. Thus, the photographed image plane is automatically discriminated and the unexposed part is automatically set simultaneously with the discrimination without using an expensive magnetic head.
