Title: Recognizing device for handwritten character
Inventor: YOSHIDA MASARU
IPC: G06K9/62
Filed: 1986-01-27
Abstract: PURPOSE:To secure recognition of handwritten characters even though they are set in the normal or upside-down directions, by delivering again information data stored in a memory to a recognizing means upside down if these characters are not set in the normal direction or plural character candidates are available. CONSTITUTION:Character data handwritten on a tablet 1 undergo input processing through an input process means and then a pre-process means. These processed character data are stored in a memory and recognized by a recognizing means. In case the characters are not set in the normal direction or plural character candidates are available, the character data stored in the memory are delivered again to the recognizing means after undergoing upside-down inverse arithmetic operation.

Title: Method and apparatus for mixing powders by air stream
Inventor: SAWAMURA MASAYUKI
IPC: B01F33/40
Filed: 1984-01-31
Abstract: PURPOSE:To perfectly mix powders without generating heat and deterioration due to mutual collisions of powders, in mixing two kinds or more of powders, by using a mixing apparatus to which a collection principle of a powder by a cyclone is applied. CONSTITUTION:Gas such as air is blown into the cylinder 13 attached to the upper part of the cyclone cylindrical part 11 of a powder mixing apparatus 1 from the tangential direction. The air stream advances in the cylinder 13 while spirally revolved by the spiral air atream generation means 131 in the cylinder 13. At this time, a different kind of powders are supplied from powder charging ports 130, 130 provided to the cylinder 13. The spiral air stream containing powders comes to a multi-layered rotary stream in the lower part of the cylindrical part 11 to enter a conical part 12. Herein, the air stream comes to a centripetal rotary stream and is gradually converted to a rising stream in the vicinity of the center and exhausted out of the system from an exhaust pipe 14. The powders receive centrifugal separation action in the conical part 12 and are fallen along the inner surface of the conical part 12 to be taken out as a powdery mixture from the collection port 120 provided to the lower part of the conical part 12.

Title: Manufacture of camshaft
Inventor: YAMAMOTO YOSHIFUMI
IPC: C23C26/00
Filed: 1988-01-28
Abstract: PURPOSE:To obtain a camshaft free from cracking in ramping parts by regulating the amount of alloy powder to be allowed to adhere to the peripheral surface of a cam base material so that it is smaller in the ramp parts than in the other parts and also applying a laser beam to the above peripheral surface while rotating the cam base material on the shaft center. CONSTITUTION:A sheet 7, e.g., of ferrous eutectic alloy powder prepared by kneading the above powder together with acrylic resin diluted with acetone is allowed to adhere to the peripheral surface of a cam base material 3. At this time, the amount of the alloy powder is reduced in the ramp parts 6 of the base material 3 so that the thicknesses of the sheet 7 are reduced in the ramping parts 6 as compared with those in the other parts. Subsequently, a laser beam 8 is applied to the surface of the base material 3 while rotating the base material 3 and the sheet 7 on the shaft center O of the base material 3, by which the base material 3 and the sheet 7 are successively remelted. At this time, the irradiation angle of the laser beam 8 is regulated so that it is smaller in the ramping parts 6 than in the other parts. By this method, an increase in the concentration of alloy components in the ramping parts 6 can be inhibited and, as a result, cracking in the ramp parts 6 can be inhibited.
