Title: Etching solution flow rate control method in photoetching equipment
Inventor: KURITA KOICHI
IPC: C23F1/08
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To provide a method to avoid non-uniformity in the etching quantity attributable to the clogging in a spray nozzle or a spray piping. SOLUTION: A spray piping 2 on which a plurality of spray nozzles 3 are mounted performs etching on a sheet to be etched by a plurality of rows of photoetching equipment parallel to the advancing direction of the sheet 1 to be etched. The flow rate and the pressure of the etching solution to be fed to each spray piping are measured for each spray piping, and when the relationship between the flow rate and the pressure is deviated from the predetermined range, feeding of the etching solution to each spray piping is stopped and the operation of the etching equipment is stopped. Alternatively, non-uniformity of the etching quantity can be avoided by forcibly increasing the flow rate in the piping deviated from the predetermined range. More rapid treatment can be taken by installing an alarm.

Abstract: PROBLEM TO BE SOLVED: To permit efficient heating by a method wherein a voltage is im pressed between a positive electrode and a negative electrode to charge an electric field on a gas flame and control the shape of the gas flame so as to be directed toward the center of the bottom of a pot. SOLUTION: A burner 12 is equipped with a negative electrode 17 and a positive electrode 18. The negative electrode 17 is arranged at the inner peripheral side of the burner 12 while the positive electrode 18 is arranged at the outer peripheral side of the burner 12.

Title: Tire distinguishing device and method
Inventor: YANASE MINAO
IPC: B60C23/00
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To distinguish whether a tire is a tire for summer or that for winter by comprising a distinguishing means for distinguishing the tire mounted on a driving shaft on the basis of an inverse of a turning radius and a determination value. SOLUTION: When the pressure of a driving wheel is reduced, the differential limited-center turning radius is shifted. When the pressure of a driven wheel is reduced, the calculation itself of the radius is shifted, so that an EDL value (determination value) is moved in parallel in the vertical direction along a line of the difference of left and right driven wheels. It is necessary that the pressure reduction is determined by comparing the horizontal part under a normal pneumatics condition and that of a pressure reduction condition.  In the procedure, the DEL values are gathered on a position of an axis of abscissas = 0, that is, on an axis of ordinates (Y axis) during a time when the differential is limited with and without pressure reduction and regardless of the position, by taking the inverse 1/R of the turning radius calculated from the driving shaft, on the axis of abscissas (X-axis), so that the pressure reduction can be easily determined by comparing the determination values on the horizontal parts slightly separated from the axis of ordinates.
