Title: Contact chip for consumable electrode arc welding torch
Inventor: HANDA KATSUMI
IPC: B23K9/26
Filed: 1989-04-19
Abstract: PURPOSE:To prevent burning of a wire and to improve efficiency of welding work by forming a notch having two surfaces where a section in the axial direction passes the center on the tip of a chip. CONSTITUTION:A through hole 1a through which a consumable electrode is passed is formed on the center of a contact chip 1 for a consumable electrode arc welding torch and further, the notch 1b having a notch angle theta and a notch length (a) is formed on the tip thereof. As a result, even if a, spherical molten part of the wire tip reaches the tip of the chip 1, since the notch 1b is formed, a possibility of the wire burning on the chip tip is reduced. In addition, even if the wire is burned on the chip tip, since the wire can be easily separated from the chip 1 by applying the force in the direction of the notch on the wire, there is no difficulty in supplying the wire at the time of next welding. Accordingly, the need for changing the chip is eliminated.

Title: Method for cooling strip
Inventor: MAKIHARA KATSUMI
IPC: C21D9/573
Filed: 1980-07-18
Abstract: PURPOSE:To prevent deformation of a strip caused by ununiform cooling by a method wherein temp. difference of the strip, longitudinal elastic coefficient and linear expansion coefficient are measured when a deformation amount is reached to a max. tolerance value and a contact length of the strip and a cooling roll is controlled so as to make different thermal stress calculated from average temp difference of the strip lower than a yield point of said strip. CONSTITUTION:Usually, when a width direction of the strip is fixed, extension DELTAL of the strip due to temp. difference DELTAT of longitudinal both end parts is imparted by a formula I when linear expansion coefficient is alpha and a length is L and strain epsilon is shown by a formula II. Further, thermal stress sigma of the strip plate is shown by a formula III (wherein E is longitudinal elastic coefficient). On the other hand, if thermal stress partially generated in cooling the strip by a practical cooling roll is made smaller than a yield point sigmaS of the strip, any deformation of the strip is not generated. That is, the temp, difference DELTAT may by controlled so as to satisfy a condition of a formula IV. As the result, quality deterioration of the strip due to deformation during cooling can be prevented beforehand.

Abstract: PURPOSE:To obtain a high-performance detector which is made at a low production cost while enabling a positive signal detection, by receiving underwater sound waves to calculate the frequency at which the short-time mean value of the level thereof rectified exceeds the long-time mean value thereof. CONSTITUTION:Underwater sound waves received enter a bandpass filter 2 at an input terminal 1 and after the extraction of the desired band alone, they are inputted into a short-time averaging unit 6 via a rectifier 3, a lowpass filter 4 and an A/D converter 5. The averaging unit 6 computes the mean, for instance, for 30sec. A long-time averaging unit 7 receives the mean of the averaging unit 6 to output the long-time mean value, for example, for 20min. The long-time mean from the averaging unit 7 is multiplied (a) times with a constant unit 8 to be applied to an adder 9, the (a) times-multiplied output of the long-time mean applied is subtracted from the short-time mean applied to the adder 9 from the averaging unit 6 and the results are outputted to a decider 10. The decider 10 determines whether sound waves as signal exist or not among those being received and the results are outputted to an output terminal 11.
