Title: Composite filler metal for build-up welding
Inventor: OHASHI YOSHIHISA
IPC: B23K35/30
Filed: 1987-03-27
Abstract: PURPOSE:To easily obtain the titled composite flux by forming mixed sintered crystal of matrix metallic powder with dispersed ceramics powder and specifying its density in the range of a specific ratio at the time of having no void and performing the combined build-up welding with the high adherent strength and an uniform distributing state of ceramics. CONSTITUTION:The composite filler metal for the build-up welding of this invention is the mixed sintered crystal of the matrix metallic powder of Cr-Ni- Fe, etc., with the dispersed ceramics powder such as Al2O3, etc., and its density is 55-98% when there is no void. Then, since said composite filler metal has low sintered density <=98%, its bond is weak and it can be welded at a low current and the heat input to a molten pool can be reduced. Moreover, when the heat input is reduced, the melting temperature becomes low and the viscosity of molten metal becomes high. As a result, a dispersed state of ceramics at a build-up zone can be uniformized.

The surface layer covers a range within 20 nm depth from the surface of the photocatalyst composite substance. Consequently, the substrate baring the photocatalyst composite substance is provided with high catalytic activity.

Title: Power supply apparatus
Inventor: OZAKI KOYO
IPC: H02M3/28
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To compensate for the voltage drop of a load side voltage due to the wiring to reduce the cost by detecting increase of an output current because a negative voltage side voltage reduces in proportion to an output current due to the voltage drop by the wiring and controlling an output voltage of the power supply circuit to rise when an output current increases. SOLUTION: When a voltage level of the input signal v1 of the voltage added in an adder 18, a duty of the output voltage v2 increases. When a voltage level of the input signal v1 is high, the duty of the output voltage v2 becomes small. Therefore, when an output current i2 becomes high, the voltage v2 of the load 2 side is lowered. Thereby, the voltage level of the input signal v1 is also lowered and the duty of the output signal v2 becomes high. This output signal v2 is supplied to the base side of the control transistor 15 to control the ON time of this control transistor 15 and also control the output voltage v1 of the power supply circuit to rise. Therefore, voltage drop by the wirings 3, 4 in the load 2 side can be compensated.
