Title: Flow rate integrating meter
Inventor: OOTA KAZUFUMI
IPC: G01F15/07
Filed: 1980-12-22
Abstract: PURPOSE:To permit the integrating of flow rate with a common arithmetic circuit by arranging common integrating units with the multiplying of input signals different in form by properly set constants with respect to the signals. CONSTITUTION:When inputting pulse train flow rate signals SD, the number of pulses is multiplied with a pulse scaling circuit 2 to generate one pulse for each integrating unit according to a scale constant Kp. A flow rate signal SF1 thus scaled is fed to an arithmetic circuit 6. When inputting an analog flow rate signal SA, these signals are converted into digital signals S0 with A/D converter 3 and multiplied by a scale constant KA with an analog scaling circuit 5 to form a flow rate signal SF2 based on the integrating unit which is fed to the arithmetic circuit 6. This permits common reception of the pulse train input and the analog input.

Title: Apparatus for washing mist eliminator
Inventor: ABE TOSHIJI
IPC: B01D46/10
Filed: 1982-10-20
Abstract: PURPOSE:To achieve the sharp reduction of equipment, the reduction of pressure loss and the increase of washing effect, by a method wherein a washing liquid is injected toward the oblique direction from a washing pipe and a mist eliminator is washed while the washing pipe is rotated on its own axis by the repelling action of a jet stream. CONSTITUTION:Two washing pipes 12 are filled with a washing liquid A supplied to a pivot part 11 from a water supply pipe 16 and said washing liquid A is injected from spray nozzles 15 by its pressure. Because this injection is performed toward the oblique direction with respect to the surface of a mist eliminator 9, it has a horizontally directing vector and a vertically directing vector. Among them, the jet stream of the horizontally directing vector imparts the driving force of its repelling action to the washing pipe 12. Two washing pipes 12 receive couple because the spray nozzles 15 attached to said pipes 12 are present at a symmetric position and start rotation themselves. This rotation is extremely smooth because vibration is suppressed by support rollers 13 provided to the leading ends of both pipes 12.

Title: Arc stabilizing method in pulse arc welding
Inventor: MITA TSUNEO
IPC: B23K9/09
Filed: 1981-11-16
Abstract: PURPOSE:To ensure transfer of droplet, stabilize arc and compensate output voltage against disturbance in welding in which droplet is separated from a wire by pinching force of peak current by making the base voltage value at the time of starting higher than that of stationary state and changing the former. CONSTITUTION:By generation of peak voltage VP, peak current becomes slightly delayed IP. When base voltage at the time of starting VBS and that in stationary state VB is made VBS>VB, the base current becomes IB and output current of welding power source becomes Im. Change of current in transfer section from IP to IB becomes gentle. The waveform of Im is changed by values of VBS etc. In the case where arc length becomes large and the average value of output voltage becomes too large, if VBS is lowered and base delay time td is lengthened, the current value IBS at starting point of transfer is lowered, DELTAABC becomes small, and arc length is shortened. In converse case, arc length is lengthened. By increasing and decreasing VBS by negative feeding back of Va, arc length, or Va can be maintained nearly constant against disturbance.
