Title: Plasma build-up device
Inventor: ENOMOTO NOBUYUKI
IPC: B23K10/02
Filed: 1991-03-19
Abstract: PURPOSE:To efficiently execute the heat input to a base metal, and to form the build-up member so that its width becomes narrow and its height becomes high. CONSTITUTION:By magnetic flux generating means (2, 3, 10) a magnetic flux having a component being orthogonal to the direction running along the center axis of a main electrode (51) and the direction of the movement is generated in a space between the tip of the main electrode (51) of a torch (1) and a base metal (59), and to an arc generated in the space concerned, deflection force is given to the relative moving direction of the torch (1) and the base metal (59) in accordance with the Fleming's left-hand rule. The arc shakes in the moving direction concerned. Metallic powder (53) supplied to the arc moves together with the arc, but by said shake, a transverse section (a cross section running along the face being parallel to the surface of the base metal) shape of the arc becomes an asymmetrical elliptical shape (roughly an egg shape), melting width (the direction being orthogonal to the moving direction) of the base metal becomes narrow, and meeting width (the direction running along the moving direction) becomes wide. In accordance with a fact that the melting width becomes narrow, build up width becomes narrow, a floating escape of a gas component in a molten metal corresponding to an expanse of the melting length is quickened and build up of high quality being free from a defect is obtained.

Abstract: PURPOSE:To prevent the chattering at the release of power supply reset or at the changeover in operation by providing a feedback circuit so as to assist the charging current to an integration capacitor through the output of a comparator and giving sufficiently the charging to the integration capacitor even when the power supply voltage rises or descends slowly. CONSTITUTION:When a voltage detection circuit 11 detects that the power voltage rises up to a prescribed voltage, a charge/discharge circuit 12 supplies a charging current to a capacitor C1 and a terminal voltage across the capacitor C1 rises. When the voltage exceeds a reference voltage, the transistor (TR) Q15 of a comparator 13 is turned on. The output is inhibited until the TR Q15 is turned on. Since a feedback circuit 16 is provided, a current three times of the collector current of the TR Q15 is fed to a TR Q19, and when the TR Q19 is turned on, a resistor R7 is short-circuited to lower the reference voltage of the comparator circuit 13, a current is conducted also to a TR Q25 constituting a current mirror circuit together with a TR Q20 at the same time thereby supplying a current to the capacitor C1.
