Title: Method for refining molten steel
Inventor: NAITO KENICHIRO
IPC: C21C7/10
Filed: 1996-08-06
Abstract: PROBLEM TO BE SOLVED: To promote decarburizing reaction and to shorten degassing treating time by blowing hydrocarbon base gas into molten steel in a vacuum vessel and forcedly and positively cooling a local position of the molten steel, at the time of executing the vacuum treatment of the molten steel by an RH method or a DH method. SOLUTION: The molten steel 2 in the vessel 1 is locally cooled by blowing the hydrocarbon base gas as the cooling gas from tuyeres 5 arranged at 50-300mm lower part from the molten steel surface position of side wall of the vacuum vessel 1 during executing the vacuum treatment. By this method, since an equilibrium constant K=Pco /(ac .ao ) of C+O=CO reaction becomes large at the local position of the cooled molten steel 2, the decarburization can be promoted. Wherein, Pco is the partial pressure of CO gas and ac and ao are the partial pressures of C and O, respectively. Then, since a solidified block 6 is formed around the tuyere 5 during gas blowing with the cooling action of the gas, the tuyere 5 is not eroded. Further, the gas blowing can be executed by using a lance instead of the blowing through the tuyere depending on the case.

Title: Soldering inspection device
Inventor: SUZUKI SHINJI
IPC: B23K1/00
Filed: 1990-08-03
Abstract: PURPOSE:To improve the quality of a surface packaging board by providing a shape measuring means which irradiates the board packaged with parts on the surface with electromagnetic waves and obtains the shape of the soldered parts at the lead ends of the parts and a soldering defect detecting means which detects soldering defects in accordance with the side surface shape thereof. CONSTITUTION:The solder is pulled up by the lead 4 under the surface tension of the solder 5 at the time of melting the solder by heating. The side face of the solder is recessed and an inclination changes rapidly at the top end of the side face of the solder, i.e., the boundary between the solder and the lead if the soldering is good. The soldering defect is detected in accordance with the side face shape of the soldered part 5 largely reflecting the non- defectiveness and defectiveness of the soldering in such a manner and, therefore, the exact soldering inspection is executed. While the thickness over the entire part of the soldered part is known if X-rays are used, the soldering inspection by measuring optically the shape (height) in the side surface part of the solder is possible as well. Contribution is made to the improvement in the quality of the surface packaging board in this way.

Filed: 1993-08-23
Abstract: PURPOSE:To inhibit the elution of metal and the generation of particles and maintain high reliability over a long term by using only a static liquid contact part under a system to allow the overflow of a part of a sump liquid in a condenser into a tower part by an overflow weir, to obtain a reflux liquid. CONSTITUTION:A refined vapor is condensed by a cooling condensation coil 8 in a condenser, then a condensate drops into a condensate sump 7 at the inner bottom of the condenser 5 and is accumulated there. In addition, a part of the sump liquid overflows into a tower part 3 from an overflow weir 6 to become a reflux liquid. The remaining part of the sump liquid is guided out of a vessel by a condensate delivery line 16, and is sent into a refined liquid storage tank 10 after being cooled by a distillate cooler 9 as a distillate. In this case, it is possible to adjust the ratio of the amount of a distillate which is actually extracted to an area outside a distillation tower and the amount of a reflux liquid which is circulated back into the distillation tower by setting the relative positional relationship between the level of the top end part 17 of the condensate delivery line 16 and the gas and liquid interfacial level 20 of the condensate sump 7 in a vertical direction.

Filed: 1989-08-11
Abstract: PURPOSE:To prevent integrated circuit break at the time of insertion of a package of an electric circuit by preparing a short package terminal for driving electric power source in a package and installing a switching circuit in which a delay circuit is built. CONSTITUTION:A connector 12 has two connector terminals 13, 14 and the connector terminal 13 is always connected to 'high level' +5V electric power source. Two package terminals 23, 24 of a package 20 are respectively bound to the connector terminals 13, 14 and short-circuit connected in the inside of the package. As a result, when a prescribed driving electric power is applied to one of the two package terminals for driving electric power source by the connector 20, the driving electric power is returned from the outer one through the inserted package and runs and works and thus the switching circuit leads the electric power to run through the package connector 12 and the package terminal 21 in prescribed order.

Title: Cut type defatting facial tissue roll and stereoscopic toilet tissue case
Inventor: MIYASHITA SHINICHI
IPC: A61L9/12
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To enable facial tissue paper to be freely cut in a size by building a facial tissue roll into a stereoscopic facial tissue paper case equipped with a cutting mechanism. SOLUTION: A tab 4 for feeding facial tissue is equipped under a cylindrical stereoscopic facial tissue paper case main body 3 made of plastic molded integrally with a blade part 6. A guide mechanism and a fixed shaft locking mechanism are equipped in the stereoscopic facial tissue paper case and a facial tissue paper roll is set in the case. Since the facial tissue paper can be fed little by little in the CW direction by a step rotary gear and a spring inside the case, unexpected paper feeding can be prevented to easily obtain only a necessary quantity of the facial tissue paper. The system to cut the facial tissue paper is preferably to use either of a system to slide a fixed blade 6 and the main body or a slide cut system to rorate the main body and the blade structured in double layers.  The facial tissue paper can be used in a free size but by a blade 6 equipped in the case tying to efficient facial tissue paper consumption.
