Title: Electrode for tig welding
Inventor: JOGAN SHIGETOSHI
IPC: B23K9/167
Filed: 1992-07-30
Abstract: PURPOSE:To prevent the generation of welding defects by specifying the tapered angle of the conical part in the TIG welding electrode. CONSTITUTION:The tapered angle of the conical part 2 in the TIG welding electrode 1 in which the conical part 2 is formed in the tip end is set for 55 to 65 degrees. For example, when a square base material made of an alloy and an electrode 1 are connected to a TIG welder, and the generation and extinction of arc are repeated while argon gas is supplied, the generation of arc from a part other than the tip end is not recognized in the electrode 1 whose tapered angle of the conical part is in the range of 55 to 65 degrees. In the electrode 1 whose conical angle is less than 55 degrees, the generation of arc from other than the tip end is comparatively few; and in the electrode with the angle more than 65 degrees, the generation of the arc from other than the tip end is comparatively many. Consequently, even if the generation and extinction of arc are repeated, the generation of arc from other than the tip end of the electrode 1 is prevented, and therefore welding is performed in accordance with a welding line.

Title: Flash discharge tube
Inventor: NAKAMURA NOBORU
IPC: H01J61/073
Filed: 1982-11-19
Abstract: PURPOSE:To reduce an impact noise as well as to make a high quantity of light and low starting voltage maintainable for hours, by letting a cathode include such a coil that surrounds with some play an electron radiation material holding body impregnated with an electron radiation material, while making up this coil so as to exist in a specific temperature range during operation. CONSTITUTION:An electron radiation material 19 is impregnated into an electron radiation material holding body 12 consisting of an insoluble metal, while a coil 14 composed of an insoluble metal wire is installed in position so as to surround the electron radiation material holding body 12 with a gap 13, and a sealing rod 10 is connected to the coil's terminal end whereby a temperature range of 800- 1,300 deg.C is designed so as to keep up during operation in this coil 14. With this constitution, temperature in a cathode is easily kept at a desired one, so that a cathode fall comes as small as negligible, relieving a degree of collision energy in an anode and thus reducing the impact noise. In addition, scatters out of the electron radiation material during operation are almost caught by the coil 14 and therefore the sedimentation of these scatters inside a tube is well reduced, preventing a quantity of light from dropping.

Title: Internal latent image type direct positive photosensitive silver halide material
Inventor: MURAI HAJIME
IPC: G03C1/485
Filed: 1983-10-31
Abstract: PURPOSE:To improve the reversal performance and aging stability by incorporating a compound contg. sulfur represented by a specified formula into an internal latent image type direct positive silver halide emulsion layer subjected to chemical surface sensitization or a hydrophilic colloidal layer adjacent to the emulsion layer. CONSTITUTION:A compound represented by the formula (where R1 is a satd. or unsatd. aliphatic residue, an aromatic residue, a 5- or 6-membered heterocyclic residue contg. N or acyl) is incorporated into an internal latent image type silver halide emulsion layer of a positive photosensitive material subjected to chemical surface sensitization or a hydrophilic colloidal layer adjacent to the emulsion layer. The compound is practically useful when the amount is about 5X10<-7>-1X10<-4>mol per 1mol silver in the emulsion layer. Though the amount is much smaller than the amount of a conventional compound, the aging stability is well improved. Accordingly, when a sensitizing dye is added to carry out spectral sensitization, the adsorption of the dye is hindered, and effective spectral sensitization can be carried out.

IPC: H01L21/027
Filed: 1994-08-30
Abstract: PURPOSE: To provide a method and device for controlling the drying speed of high-viscosity chemical material applied on substantially flat surface of a rotary object. CONSTITUTION: The drying speed of chemical materials is controlled by controlling the local atmosphere, where an object 302 is rotating locally, the saturation level of a solvent in the space adjoining a surface 304 of the object 302. By rotating the object 302 in a vapor containing the solvent, the evaporation of the solvent from a chemical material is delayed, so that the ratio at which the chemical material is dried and becomes thicker is also delayed. By applying a thin layer of the solvent to the surface 304 of the object 302, the spreading of chemical material or diffused-application also becomes easier, while premature drying of chemical material is avoided.
