The sample on the plate 8 is vaporized by switching the cock 4 and heating the heater 3 to 2,600 deg.C, and the sample vapor is introduced into the plasma 5a. Damage or consumption of the heater causing by a strong acid is eliminated because the direct contact between the heater 3 and the sample is prevented by the sheet 8.

Title: Disk cutter
Inventor: OKAMOTO TATSUICHI
IPC: E21D9/087
Filed: 1994-06-10
Abstract: PURPOSE:To improve the extent of workability in crushing a residual part existing between two disks by setting up plural pieces of disks with each face on the circumferential part, on a base circumference, and installing each auxiliary cutter of specified height among plural pieces of disks. CONSTITUTION:A residual part being formed between two disks 2a and 2b due to rock crushing is advanced and thereby its tip touches an auxiliary cutter 3a. In this case, each projection of three auxiliary cutters 3a to 3c should be set to 1/5 to 1/2 to each height of four disks 2a to 2d. Therefore, each opening of respective tip parts of these disks 2a to 2d is secured like those of the conventional ones. Thus, the auxiliary cutter 3a to 3c come to a state that each wedge is driven into the residual part, so a crack grows larger. These residual parts among these disks 2a to 2d to be formed due to a crush of natural ground by these disks 2a to 2d are advanced forward, whereby they are crushed by the auxiliary cutters 3a to 3c. With this constitution, any increase in friction at each root among these disks 2a to 2d is checked and thus their crushing can be advanced forward.

Title: Production of composite steel ingot

IPC: B22D7/02
Filed: 1984-07-25
Abstract: PURPOSE:To improve the uniformity of the penetration in the circumferential and height directions of a steel ingot by disposing the steel ingot provided preliminarily with a slag layer on the outside circumference in a water-cooled casting mold, inserting consumable electrodes into the cavity and executing electroslag building-up. CONSTITUTION:The water-cooled casting mold 1 is imposed on a water-cooled surface board 8 and the steel ingot 2 is placed concentrically therein. The consumable electrodes 3 are inserted to the space thereof. Plural current collecting brushes 9 are attached to the side face of the board 8 and are made rotatable. The part where the current density distribution is nonuniform is thus evenly given to the circumferential direction of the steel ingot 2 and the quantity of the heat to be transmitted to the ingot 2 is averaged. When the electroslag building- up is started, the electrodes 3 are melted by the resistance heat of a slag bath 4 and form a molten metal bath 5 under the slag bath. Said bath forms a solidified metal 6 and fills the cavity. The slag bath 4 is consumed by forming a slag skin 7 between the metal 6 and the mold 1 but is uniformly replenished by a slag layer 12 by as much as the bath is consumed.

Title: Electric dust collecting unit
Inventor: OTAKE SHIGEMITSU
IPC: B03C3/40
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To safely perform the replacement or maintenance and inspection of a dust collecting unit while reducing the pressure loss to an air flow. SOLUTION: In an electric dust collecting unit, the direction of needle electrodes 11, 11,... is set laterally with respect to an opening part to prevent danger such that the finger of a worker is injured by the needle electrodes at a time of the replacing work or maintenance and inspection work of the dust collecting unit to ensure safety. Therefore, the electric dust collecting unit can be widely adapted not only to an industrial air cleaner but also to a household air cleaner. In addition, since a conventional box-shaped needle electrode holder is not used, an air flow channel is not opressed and pressure loss can be markedly reduced and, as a result, a dust collecting unit, in its turn, an air cleaner can be miniaturized.
