Title: Cutting device
Inventor: TAKATANI MASARU
IPC: B24B27/06
Filed: 1986-12-12
Abstract: PURPOSE:To eliminate any drop of cutting accuracy due to wear on one same area of a cutting band material and aim at a long service life of said material by feeding said cutting band material little by little in one direction while repeating normal/reverse feed thereof, in a cutting device for hard and brittle material. CONSTITUTION:When a workpiece 30 to be cut is pressed on a cutting band material 1 due to rising motion of a machining table 31, then a reversible motor 22, torque motors M1, M2 and a motor 23 are driven while cutting oil being ejected from a grinding grains supply part 32 so that a grooved roller 10 is rotated in the direction of an arrow mark, for instance, a cutting process is carried out under normal run of the band material 11. Then, the supporting rod l of a seesaw section 4 also swings leftward to reduce a distance between rollers in No.1 band storing part 7 and to increase a distance between rollers in No.2 band storing part 18. Next, when the band material 1 is fed by a prederfermined length, each motor reverses the direction of its rotation to carry out cutting of the band material 1 through the reverse feed and also to change the direction of rotation before the amount of reverse feed reaches the amount of normal feed, and such action is repeated successively. Accordingly, wear does not take place only in one area to enhance the cutting accuracy because the cutting band material is fed a little by little while it is subjected to repetition of normal and reverse feed.

Title: Helicopter
Inventor: SHIBAYAMA KENJI
IPC: B64C7/00
Filed: 1991-11-13
Abstract: PURPOSE:To ensure a lower operation space and prevent an engine from the intake of foreign sustances by forming the upper width of the fuselage larger than the lower one while disposing the engines on both side ends on the upper part of the fuselage to drift rotor blown-down air sidewise of the fuselage. CONSTITUTION:While a helicopter has the fuselage 13 having the upper width larger than the lower one, engines 4 are disposed on both side ends of the fuselage 13 formed with a flat upper surface. Rotor blown-down air 12 generated by a rotor 2 disposed through a rotor rotating shaft 3 on the center part in the upper surface of the fuselage 13 is drifted sideways, so that the rotor blown- down air 12 flowing downward is canceled to hold an operation space below the helicopter under the satisfactory weak wind condition. Also, even when the helicopter is hovering near the ground, wind generated to circulate vertically is canceled and the engine 4 is prevented from taking in foreign substances like gravels without degrading the hovering flight performance.
