IPC: H01L31/04
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To evade unnecessary alarm generation by giving an alarm when hours wherein the mean output current value of a specific solar battery circuit decreases below a rate set for a solar battery circuit having a maximum mean output current value increase above set hours. SOLUTION: A solar battery current measurement part 17 measures mean output current values I1, I2...In of respective solar battery circuits. A mean output current arithmetic part 18 finds the mean output currents of the respective solar batteries in unit times. On the basis of the largest value among the mean output currents of the respective solar battery circuits in the unit times as a reference value, a mean current rate arithmetic part 19 calculates the rates of the mean output current values of other solar battery circuits to the reference value. A current decrease circuit detection part 20 detects a solar battery circuit whose mean current rate is less than a set value.  A successive number count part 21 for current decrease unit times counts the successive current drop unit times of the current decrease circuit and sends out a signal for making an alarm generation device 13 to perform alarming operation when the count value exceeds a set value.

Title: Multilayer buildup fillet welding method
Inventor: UCHIDA NORIO
IPC: B23K9/127
Filed: 1986-01-28
Abstract: PURPOSE:To stabilize the quality of multilayer buildup fillet weld by setting the welding current, welding speed, etc., by fixing the reference bead width accordingly, by deciding a logical necessary pass from that and the leg length and by performing the welding of the prescribed leg length by deciding the welding passes and the welding speed of the final pass therefrom.

The minimum number of passes necessary for forming the bead width larger than the leg length X on the initial layer, namely the logical pass number (n) is then found. The unwelded length (r) of the case of completing the welding before one pass of the logical necessary pass (n) is then found. In case of the unwelded length (r) being smaller than the reference value (n-1) is made the final pass and the welding of the prescribed leg length X is performed as well by reducing the welding speed. In case of the unwelded length (r) being larger than the reference value (n) is made the final pass and the welding of the prescribed leg length X is performed by increasing the welding speed. In this way, the welding conditions setting work is simplified and the welding quality is stabilized.

Filed: 1994-01-18
Abstract: PURPOSE:To efficiently obtain the uniform low oxidized titanium-containing powder by reducing and sintering titanium dioxide in the presence of an ammonium-adsorbed substance as a reducing agent in a low oxygen concentration atmosphere. CONSTITUTION:Titanium dioxide is reduced and sintered in the presence of an ammonium-adsorbed substance in a low oxygen concentration atmosphere to produce a lowly oxidized titanium-containing powder.
