Inventor: YOSHIKAWA KUNIHIKO
IPC: C21D7/02
Filed: 1979-11-30
Abstract: PURPOSE:To make possible the use of a metal pipe without requiring heat treatment after cold working at the time of producing the metal pipe, by cold working the same by combining reduction ratios and diametral thickness working ratios under such conditions in which the differences in the crystal grain sizes in the thickness direction and axial direction of the pipe assume less than specific values. CONSTITUTION:At the time of producing a metal pipe through cold working, the product metal pipe is made usable with the strength at the cold working as it is without making heat treatment after the cold working. To this end, the pipe is cold worked and finished by the combination within the region (I)(II) of reduction ratio PHIl and diametral thickness working ratio Qepsilon at which the differences between the crysstal grain sizes of the section in the thickness direction of the metal pipe and the crysstal grain sizes in the axial section of the pipe are <=0.5 in ASTM grain size. Here, reduction ratio PHIl=(S-So)/So, So, sectional area prior to working, S; sectional area after working, diametral thickness working ratio Qepsilon=PHIt/PHIc, PHIt; thickness reduction ratio, PHIc; diametral reduction ratio. According to this method, the pipe may be used as it is without making any treatment even if the cold reduction ratio is >=20%.

Title: Automatic welding method
Inventor: TSUJI TATSUO
IPC: B23K9/095
Filed: 1978-12-13
Abstract: PURPOSE:To obtain a uniform welding over the entire weld line, by varying the welding current and voltage according to the inclination angle of weld line, in a torch of which relative angles to the projected lines of weld lines of two- and three- dimensional curves inclining with respect to the horizontal plane are unchanged. CONSTITUTION:When the vertical inclination of weld line shaped like a saddle is large, the welding current and voltage are lowered and raised in the upward slope and downward slope, respectively, according to the inclination of the weld line so as to improve the bead shape. The rotating angle of the torch in the process of trace welding is detected by a sensor 5 provided on the phi-axis of the torch 4. The torch 4 rotates once around the phi-axis in every revolution about a branch pipe 2 along the weld line. Since the relative angle of the nozzle with respect to the projected line of the weld line 3 is not changed, the angle of revolution may be detected from the rotating angle, taking the rotating angle at an arbitrary reference point 0 on the line 3 as 0 deg.. Then, the torch position is detected from the angle of revolution, and the welding current and voltage corresponding to the inclination of the weld line in that part with respect to the horizontal plane are applied.

Filed: 1986-07-03
Abstract: PURPOSE:To eliminate or alleviate the effect of scattering between valleys, by constituting an element using a semiconductor material, in which energy difference between an upper valley and a lower valley is sufficiently large. CONSTITUTION:On a semi-insulating GaAs substrate 10, n-GaAs and n<+>-InGaP, which are active layers, are epitaxially grown continuously. Then, the InGaP layer is etched away, with a drain region 23 being made to remain. Ions of n-type impurities are implanted, and a source region 11 is formed. Energy difference between an upper valley and a lower valley in a channel region 12 is about 0.3 eV. Whereas, the energy difference in the drain region 23 is about 0.37 eV. Electrons have as much difficulty in entering the upper valley as increased difference between both values. Even if this element is used at higher voltage, decrease in electron speed due to scattering between the valleys does not occur.

IPC: H03H11/26
Filed: 1990-06-15
Abstract: PURPOSE:To take out two base band signals without any delay phase difference by providing a variable delay circuit for one input base band signal and controlling the variable delay circuit so as to eliminate relative delay phase difference by a phase comparator for detecting phase difference between both the base band signals and an integrator. CONSTITUTION:One of the base band signals inputted from input terminals 1 and 2 is branched to signals to a phase comparator 7 and an output terminal 9 by a variable delay circuit 3 and a branching circuit 6A after passing through an LPF 5A, and the other signal is branched to signals to the comparator 7 and an output terminal 10 by a fixed delay circuit 4, LPF 5B and branching circuit 6B. The comparator 7 detects the phase difference between the both base band signals and outputs a detection signal. An integrator 8 smooths this detection signal and outputs a direct current voltage. The circuit 3 inputs this direct current voltage and changes a delay amount in a certain direction so that the phase difference of the comparator 7 can be zero. Thus, at the outputs of output terminals 9 and 10, the two base band signals can be obtained without any relative delay phase difference.

The group thin-film having wavelength sensitivity can easily be formed by applying a vacuum deposition method, etc. in the photoelectric sensor.
