Title: Arc welding method for al base composite material
Inventor: TANAKA KAZUO
IPC: B23K9/23
Filed: 1986-06-09
Abstract: PURPOSE:To prevent the defective fusion of mutual base metals by setting the root gap of a butt part specifically and performing a TIG welding by making the arc length at <the specific value. CONSTITUTION:An AC power source 11 is provided between Al base composite material base metal 1 and the electrode 6 of a torch 2 and TIG welding is performed by feeding the filler metal 3 of Al or Al base alloy. In this case, the root gap 12 of an I groove part is set in 0.5-5mm, so the molten metal surely reaches upto the back face side of the base metal 1 and the base metal each other can strongly be joined. Also, since the arc length is set in <= 5mm the reduction in the mechanical property due to the effect of the welding heat with the excess spread of the arc can be prevented. Consequently the integral joining method without the problems of an airtightness, heat transfer and conductivity is established.

In this way, the time required for writing and reading various welding conditions is shortened remarkably, and the manual switch operation in case data is input is not required, and therefore there is no error at all for setting the welding condition.

Abstract: PURPOSE:To obtain an audio signal having good quality, by forming a compensating signal interpolating a missing part of a signal during the period of impulsive noise in an audio equipment by an analog circuit with a simple circuit constitution. CONSTITUTION:An input audio signal S1 outputted from a delay circuit 2 is applied to a sample-and-hold circuit 5 and a differentiating circuit 6.

The output signal S3 of the circuit 5 is given to an adder 10. Further, the differentiating circuit 6 outputs a signal S4 differentiating the signal S1 and feeds it to a sample-and-hold circuit 7. Since the circuit 7 is operated so as to hold a signal level of a time position just before the period of pulse width of the control signal S2 in the signal S4 over the period of the pulse width of the control signal S2, a signal S5 is applied to a gate circuit 8 from the circuit 7. An output signal S6 from the gate circuit 8 is applied to an integrating circuit 9 and the integrating time constant is changed according to an input voltage value, and the signal S3 and a correcting signal S7 outputted from the integrating circuit 9 are added to the compensating signal S7 at the adder 10.

Title: Bipolar voltage detecting circuit
Inventor: TANAKA KOUICHI
IPC: G01R19/22
Filed: 1983-07-21
Abstract: PURPOSE:To make it possible to set a detection level to the resistance value of a resistor element with higher accuracy, by a bipolar voltage detecting circuit which can set a detection level to an arbitrary value with high accuracy in a state stable to a temp. CONSTITUTION:Differential transistor pairs Q10, Q11 and Q12, Q13 are used and common potential is applied to the bases of Q11 and Q12 by the resistance division of stabilized voltage Vs while potential determined by the ratio of resistors R16-R18 is respectively applied to the bases of Q12 and Q13. In this case, the base potential of Q10 is lower than common potential and the base potential of Q13 is higher than the common potential. Q11 and Q12 in an ON-side are constituted so as to be mutually compensated in the base currents thereof. The measuring error of a detection level is shown by a constant formula and, by making hFE of Q11 and Q12 same by making Q11 and Q12 complementary from said formula, a set error can be theoretically brought to zero. As mentioned above, because a detection level can be set by the selection of a resistor element and determined by the resistance value of said resistance element, the detection level can set with high accuracy in a state stable to a temp.

Abstract: PURPOSE:To accurately measure a length of the let-out line, by a device wherein magnetic materials are attached on the fishing line with a given interval therebetween and the number of pulses is counted which are generated when the magnetic materials pass through coils. CONSTITUTION:A plurality of magnetic materials are attached on a fishing line with a given interval therebetween, while the line is let out to pass through coils fixed on a fishing rod. With the fishing line being let out, a counting circuit calculates the number of pulse signals which are generated when the magnetic materials pass through the coils, so that the length of the let-out fishing line is measured. For example, magnetic materials 5 are attached on a fishing line 2 with a given interval therebetween. The number of pulse signals from an oscillator 11 which are generated every time when the magnetic materials 5 pass through coils 8a, 8b upon letting-out of the fishing line are counted via an amplifier 12. Thus, the counted result is displayed on an indicator 13. By providing a part of coils 8a, 8b and adding a line direction detecting circuit 14, it becomes possible to decide whether the fishing line is being let out or wound up.
