Title: Method for controlling groove profiling in gas shielded metal arc welding
Inventor: ONO HIDEHIKO
IPC: B23K9/127
Filed: 1984-02-02
Abstract: PURPOSE:To control easily and economically a torch so as to profile exactly a groove line by ejecting alternately a control gas having the potential inclination different from the potential inclination of a shielding gas from both right and left sides of a welding torch and controlling the movement of the welding torch in the transverse direction of the groove so that the right and left arc lengths are made equal. CONSTITUTION:A shielding gas (Ar, etc.) is ejected around the arc 5 generated between the top end of a welding wire 3 and materials 4 to be welded from a nozzle 6 to shut off air. A control gas (gaseous carbon dioxide) 8 is alternately ejected for specified time from holes 1a, 1b punched on both sides at the bottom end of a welding torch 1 in this state to oscillate the arc 5 to the right and left around the wire 3. The arc voltage when the arc 5 is oscillated to the right side wall 4b and left side wall 4a of the groove is detected and the torch 1 is moved in the transverse direction of the groove so that the arc lengths lR, lL are made equal. The torch 1 is thus moved to profile the weld line.

Title: Strain measuring device
Inventor: KAI TOKIO
IPC: G01B11/16
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To accurately perform the correction to the temperature change even when a local temperature change is generated in an object to be measured without any temperature distribution measuring instrument by fixing a first optical fiber part to the object, continuously arranging a second optical fiber part through a hollow tube, and providing a play between the hollow tubes. SOLUTION: An optical fiber 1 is adhered and fixed to an object 2 to be measured in sections 1a-1b. Then, the optical fiber 1 is returned to pass a hollow tube 9, and juxtaposed in the sections 1c-1d to the sections 1a-1b. Because a play is formed in the sections 1c-1d, the optical fiber becomes independent from the expansion/contraction of the object 2. When only the temperature is changed, the strain distribution in the sections 1a-1b and the sections 1c-1d is measured by a strain distribution measuring instrument 5. The temperature dependent initial strain distribution quantity is subtracted from the respective temperature dependent strain distribution quantity to the sections 1a-1b by an initial strain canceler A6 and to the sections 1c-1d by an initial strain canceler B7, and outputted to a signal processor 8.  When the output of the canceler B7 is subtracted from the output of the initial strain canceler A6 by the signal processor 8, the output of the actual strain distribution becomes zero.

Abstract: PURPOSE:To obtain a feedback signal with an inexpensive configuration by detecting the phase rotation of 3-phase AC voltages produced by a tachometer generator to detect the rotating direction of a motor, and switching the DC voltage in response to the speed corresponding to the output to positive or negative voltage. CONSTITUTION:The output voltage of a tachometer generator 3 is rectified, smoothed, and converted to negative or positive voltage via inverting amplifiers 12a, 12b.

When the motor is normally rotated, a logic product circuit 17a operates to conduct the photocoupling element 13a, thereby outputting the output of the amplifier 12a becoming negative voltage as the feedback signal. At reverse rotating time, a logic product circuit 17b operates to conduct the photocoupling element 13b, thereby outputting the output of the inverting amplifier 12b as a feedback signal.

Abstract: PURPOSE:To obtain an excellent magnetic tape by vacuum-depositing a ''Permalloy'' thin film on a substrate while limiting the distance of a mask substrate for shielding high incident angle components of vapor atoms in the early stage of film formation, and forming a film of vertical magnetization on the ''Permalloy  '' film. CONSTITUTION:While the magnetic tape substrate 1 is run along a cylindrical can 7 as shown by an arrow A, masks 10 and 11 are arranged between a vapor source 12 and the can 7 and the ''Permalloy '' thin film 2 is vacuum-deposited through a slit S.

Consequently, the film 2 is oriented by such crystal growth that the ''Permalloy  '' film necessary for forming the film of vertical magnetization of a Co-Cr film on the film 2 has a (111) surface parallel to the film surface. Thus, the magnetic tape with superior electromagnetic characteristics is obtained.

Abstract: PURPOSE: To prevent the miss orientation due to the exciting current of the transformer by computing the orientation value with the instantaneous voltage value as the zero and 180° in the current phase and selecting the larger result as the true value.  
     CONSTITUTION: The system voltage and current introduced through respective current transformers are introduced to the input terminals 41 and 42. The pulse signals generated with zero point pulse generating circuits 43-H and 43-L which is fed with the system current when the phase of the current is 0° or 180° are each fed to the voltage derivation circuits 44-H and 44-L with which the system voltage is derived each time the pulse signal is applied.

The voltage obtained in the circuit 46 through multiplica tion the settled reactance of the system current is fed to the circuit 47. Thus, the number of pulse is generated corresponding to the frequency inversely proportional to the input level. The pulses which will pais while the signals are derived from the gate circuits 45-H and 45-L are derived by circuits 48-H and 48-L. The pulses larger in the number among those derived is derived by the circuit 50 thereby orientating the trouble point.

Filed: 1993-01-11
Abstract: PURPOSE:To prevent erroneous function due to the effect of ground bound by performing the timing control of a data latch based on the detection of transition of output from a sense amplifier. CONSTITUTION:During an interval when a sense amplifier produces no output, a transfer gate 23 is sustained in ON state. When the sense amplifier produces an output and voltage transition takes place at an output node A, an output data is transferred to a data latch 7. At that time, a transition detection pulse generating circuit 10 outputs a detection pulse and an RS latch 13 is reset by the rising edge of the detection pulse. Since outputs from all circuits 10 are fed to a NOR gate 14 in the latch 13, the latch 13 is reset when output voltage transition takes place in at least one sense amplifier system. Consequently, a gate 23 is turned OFF and an output data is held in the latch 7. Upon elapse of delay time set in a delay circuit 16, the latch 7 is set and the gate 23 is turned ON. This constitution prevents erroneous function without causing any difficulty in the setting of delay time.
