Abstract: PURPOSE:To perform welding work stably by providing a setter for regulation of welding outputs, a detector for actual welding voltage and current, and an operating device for comparison thereof to an electric power supply device for welding devices, and controlling control elements for output voltage and a motor for feeding a welding wire in accordance with the compared values thereof. CONSTITUTION:In an output terminal 14 from a smoothing circuit 13 for DC secondary current in an electric power supply section of a welding device, the welding voltage and current under welding work are drawn out and detected with a shunt 19 for detection and the values thereof are inputted via an input circuit part 21 to a logical arithmetic circuit 22 of a microcomputer. At the same time, the set values of voltage and current are inputted from a setter 20 for regulation of welding outputs to the circuit 22. Both input values are compared and subjected to feedback operation. The voltage of the welding output and the driving of a motor 18 for feeding a welding wire are controlled by control circuits 23, 24 in such a way that the welding output is brought close to the set value infinitely, whereby the welding work is performed stably.

Title: Slip detecting device
Inventor: HORIUCHI TOSHIO
IPC: B25J15/08
Filed: 1988-06-16
Abstract: PURPOSE:To detect accurately a slip between a material body and a contact shoe without a damage of the material body by accepting a pressure sensor in a substrate, providing a contact shoe made of a frexible material in the substrate, and forming the contact shoe with a swelling part projecting from a substrate surface. CONSTITUTION:When a slip is generated on a contact surface between a swelling part 5 of a contact shoe 3 made of a frexible material and a material body 17, the contact shoe 3 oscillates shearingly and disorderly and an internal pressure P fluctuates with this oscillation. This fluctuation of the internal pressure P is output as a slip signal by a pressure sensor 7 connected with the contact shoe 3 via a substrate 1. At this stage, a direct component of the pressure sensor 7 reflects a contact of the contact shoe 3 and the material body 17, and the fluctuated part reflects a slip between the contact shoe 3 and the material body 17. When the inside of the contact shoe 3 is full of a fluid 15, a shearing oscillation of the contact shoe 3 corresponds to a fluctuation component of the output.

IPC: H01P5/04
Filed: 1979-11-15
Abstract: PURPOSE:To adjust the Q at load and to avoid the change in the equivalent electric length inside the resonator, without dismounting the cavity resonator, by changing the coupling angle of a coupling loop through loosing the fastening screws and fixing the screws at a prescribed angle. CONSTITUTION:An external conductor 22 for input and output plugs can be rotated manually by loosing a little fastening screws 18, and a coupling loop 14 rotates around a rotary center line X-X'. After adjusting the coupling loop 14 according to Q at load to be adjusted, the coupling loop 14 can be set to a cavity resonator with a given relation by fastening the fastening screws 18. Further, since an external conductor 12 is electrically connected to a short-circuit bar 11 with the spring effect of a spring washer 19 even during said adjustment, the adjustment of the load Q can be made with a stable electric state. Further, since the length of loop is not changed even with the coupling loop 14 rotated only with the equivalent area changed, the Q at load can be adjusted without changing the equivalent electric length inside the cavity resonator.
