Title: Submerged arc welding on downward slope
Inventor: OKUDA NAOKI
IPC: B23K9/18
Filed: 1981-11-13
Abstract: PURPOSE:To prevent generation of defects such as concave bead, overlapping etc. in welding in which slag is formed on molten metal and the molten metal solidifies on a downward slope by specifying solidifying temperature and viscosity of the slag. CONSTITUTION:Downward slope welding is performed forming slag of which solidifying temperature is 850-1,400 deg.C and viscosity at 1,450 deg.C is <=5 poise, and in case where solidifying temperature is 850-1,200 deg.C, viscosity at 1,200 deg.C is >=5 poise, on molten metal. When the solidifying temperature is below lower limit, generation of slag is increased and concave bead is formed. At the same time generation of defects such as overlapping etc. is increased remarkably. When the temperature is above upper limit, generation of concave bead is eliminated.  However, defects such as slag inclusion, undercut etc. take place. When the  viscosity exceeds the upper limit at 1,450 deg.C, that is, temperature of starting  solidification of the molten metal, frequency of occurrence of defects such as  slag inclusion, undercut etc. increases, and when it is below the lower limit at  1,200 deg.C, a temperature at which inside of the bead solidifies completely, concave  bead is liable to be formed.

Title: Semiconductor output circuit
Inventor: SHIBAGAKI TARO
IPC: H03F3/45
Filed: 1987-07-22
Abstract: PURPOSE:To improve the high speed response of an output waveform by inserting a resistor between collector of two transistors(TR) in Darlington connection and increasing the collector potential of the input TR more than the collector potential of the output TR. CONSTITUTION:Resistors 13b, 13c are inserted between collectors of TRs 11, 12 in Darlington connection. By connecting the collectors of the TRs 11, 12 via the resistors 13b, 13c, the high speed switching of the TRs 11, 12 are performed for the change of carrier and since the current flowing to the TR 12 lifts up the collector potential of the TR 11 by the resistors 13b, 13c, the saturated TR 11 is prevented.

Title: Exposing method
Inventor: NIHEI TOMOMICHI
IPC: G03F1/38
Filed: 1990-07-13
Abstract: PURPOSE:To prevent the contamination of a mask by a photosensitive resist and the consumption of the resist by subjecting the resist to contact exposing by using a mask consisting of the thin film of a fluorine compd. formed on a mask surface on the side where the mask comes into tight contact with the resist. CONSTITUTION:A fluorine compd. layer is formed in place of an org. silicone resin on a mask surface to lower the adhesive strength between the mask and the resist, by which the peeling of the resist is eliminated even if the relatively thick resist layer is formed. Namely, the photosensitive resist is subjected to the contact exposing by using the mask consisting of the thin film of the fluorine compd. formed on the mask surface on the side where the mask comes into tight contact with the resist. The contamination by the adhesion of the resist to the mask surface in the contact exposing method and the consumption of the resist are prevented in this way and the prescribed exact patterns are obtainable without forming again the thin films with the same mask. This method is applicable to thick resists as well.

Thus, the application of tempering treatment to the place other than the high toughness part 10b can be prevented. By flowing the electric current to the place to form the high toughness part 10b, it is heated to the tempering temp. of the Al transformation point or below, and it is held to the same temp. for several second to several tens seconds and is thereafter cooled in a liq.
