Title: Measuring instrument for surface area of metallic material
Inventor: NISHIKAWA YUUJI
IPC: G01B7/32
Filed: 1978-09-30
Abstract: PURPOSE: To obtain a measuring instrument that can measure correctly and simply a surface area of complicated shape by measuring the maximum dissolution current when the electrolyte is active.  
     CONSTITUTION: When voltage is impressed between a measured metal 3 and an electrode 4, dissolution current flows between them. By changing the voltage on the condition a constant potential polarization curve is obtained through the connection between the dissolution current and the electric potential near the measured metal 3. In this case the maximum dissolution current value is shown and it is known that this maximum dissolution current is proportional to the area of a matter when it is of the same material. And this current makes no connection with histories such as material temperature, working, etc. and is constant. Regarding standard materials, if the maximum dissolution current density pecular to a material is given, it is possible to measure correctly and easily the surface area of any metallic of complicated shape by detecting its maximum dissolution current IM and operate IM/δ.

Title: Method for starting tapping of vessel for molten steel
Inventor: OMIYA SHIGERU
IPC: B22D41/46
Filed: 1985-06-05
Abstract: PURPOSE:To decrease considerably the inclusion-type defects of an ingot by packing a packing consisting of a mixture composed of a specific flux and carbon grains or carbon fibers into the tap hole of a vessel prior to receiving of a steel, operating a sliding open/shut device to open the same so as to allow the packing to fall by gravity and tapping the molten steel. CONSTITUTION:The hole of a stationary plate 4a of the sliding open/shut device 4 provided to the bottom of a ladle 1 is made dissident with the holes of a sliding plate 4b and long nozzle 5, then the packing 3 consisting of the mixture composed of the low melting flux particles consisting of 20-70% CaO and 30-80% SiO2 as well as the carbon grains or carbon fibers is packed into the tap hole 2. The plate 4b and long nozzle 5 are slid in an arrow direction after receiving of the molten steel in the ladle 1 so that the position of said holes is made coincident with the hole of the stationary plate 4a. The molten metal falls therefore into a tundish 6 upon falling of the packing 3. The packing falling into the molten metal is melted immediately without being sintered and is separated and floated from the inside of the molten steel and therefore the packing does not intrude into a casting mold 8 by passing through an immersion nozzle 7 as in the conventional practice. The contamination of the molten metal is thereby thoroughly prevented. The inclusion-type defects of the ingot 9 are thus considerably decreased.

Title: Dissolving device of semiconductor thin film
Inventor: MATSUNAGA HIDEKI
IPC: G01N1/28
Filed: 1984-06-15
Abstract: PURPOSE:To reduce impurities in a sample solution by vibrating a semiconductor thin film sample in an airtight case or dissolving the semiconductor thin film with hydrofluoric gas. CONSTITUTION:A sample wafer 9 coated with a semiconductor thin film 8 is stood against a wafer carrier 3 and a hydrofluoric acid solution 10 is put in a beaker 2 and heated by a heater 11 if necessary. Consequently, the thin film 8 is dissolved by hydrofluoric gas 12 and its dissolved solution 13 is dropped on a saucer 4. If the sample 9 is vibrated by a vibrator 5c, the dropping efficiency of the dissolved solution 13 is improved. Since the sample 9 is made airtight in the case 1, the sample 9 is directly dissolved with the hydrofluoric gas 12 without acid dissolution and highly accurate detection is attained. Since the quantity of impurities is extremely small in the hydrofluoric gas 12 even if impurities are included in the hydrofluoric acid solution 10, the quantity of the impurities in a collected solution 13 is also reduced. In addition, the dissolved solution 13 can be collected for a short time by vibrating the sample 9.

Title: Method and device for heating
Inventor: SAITO SUSUMU
IPC: B23K1/012
Filed: 1989-05-16
Abstract: PURPOSE:To execute a uniform heating and reflow soldering with high reliability by providing hot wind blowing parts and sucking parts respectively at >=2 points at specific intervals, thereby blowing the hot wind to materials, such as printed circuit boards, to be heated in the direction approximately perpendicular thereto at the heating of the materials to be heated, such as printed circuit boards. CONSTITUTION:The hot wind blowing parts and hot wind sucking parts are so provided as to exist respectively at >=2 points at the intervals shorter than at least either of the width and length of the materials to be heated. The hot wind blown from a hot air generator passes spaces 10 for blowing out the hot wind and is blown out of nozzles 7. This wind falls onto the circuit boards 11 and flows horizontally along the boards. Since the spacing between the nozzles 7 are set shorter than the size of the circuit boards 11, the hot wind blows against the hot wind coming out of the next nozzles and flows simultaneously upward. This hot wind returns to he suction port of the hot air generator by passing the spacings 9 or holes. The thermal conductivity of the hot wind and the materials to be heated is improved in this may and the heating reflow of eutectic solder with the decreased temp. fluctuations is possible.
