Title: Method for forming hard edge of saw and thickness adjusting device for saw working machine used therefor
Inventor: KOJIMA KIYOHIKO
IPC: B23D61/04
Filed: 1988-10-28
Abstract: PURPOSE:To improve efficiency and precision in work when forming the edge of a band saw, a circular saw and the like for cutting wood, light alloy, etc., by cutting the cut piece of a rod material made of hard alloy to substantially equal angle to the face angle of the edge of a saw and welding after alignment. CONSTITUTION:A small piece 2 is cut from a rod material made of hard alloy, electrically welded to the edge of a saw 3, and it is polished and shaped to form the edge of the hard alloy. When the small piece is cut from the rod material made of the hard alloy, a cutting face is cut at an inclination equal to an angle obtained by adding the clearance angle of a cutting edge and the face angle thereof and the small piece 2 is welded, thus the number of works for polishing being saved. The saw clamp plate 10 of a saw working machine used for forming the hard edge is slidably attached to a main body frame 13 and fixed by an adjusting screw 14. Since the saw 3 is pressed to the saw clamp plate 10 by a saw clamp cylinder 8 during a welding work, if a distance between the center lines of the small pieces 2 is a half of the thickness of the saw 3, the center face of the saw 3 and the center of the small piece 2 are aligned.

Title: Radar
Inventor: HARA YOSHIHISA
IPC: G01S7/40
Filed: 1988-10-27
Abstract: PURPOSE:To remove a clutter signal stably by providing a radar with a frequency sweeper for generating a voltage for control a reference frequency and an adder which detects and holds a minimum output of an integrator attributed to a sweeping voltage thereof to be added to an own speed detection output. CONSTITUTION:A correction mode allows a switch 9 to be connected to a frequency sweeper 5. Under such a condition, a frequency is swept with the sweeper 5 in a certain range to be converted into a voltage and inputted into a receiver 1 to vary a reference frequency (RF) thereof. When an error of the RF is zero, an output of an integrator 4 is also zero with an output of the sweeper 5 down to zero. Therefore, when the RF is swept with the sweeper 5 near zero to hold the output of the integrator 4 with a minimum holding circuit 6, it gives an error difference of the RF. In an normal operation thereafter, the switch 9 is connected to an adder 8. Then, a frequency error portion of the holding circuit 6 is added to an output of a conventional own speed detector 7 and the results are inputted into the receiver 1, thereby enabling correction of an error of the RF.
