Title: Horizontal continuous casting method
Inventor: TAKAMURA KOICHI
IPC: B22D11/20
Filed: 1993-12-24
Abstract: PURPOSE:To sufficiently cool molten metal in a mold and to improve the quality of a cast billet by transferring pressure signal to a bending cylinder at the time of stopping drawing-out of the cast billet and pressing cooling blocks to the mold. CONSTITUTION:At the time of drawing out the cast billet 12 completing the solidification from the mold 21, the solidified shell is separated from the inner wall of the mold 21 and advanced. Intermittent drawing-out is controlled with a controller 50 so as to alternate the stopping time for growing the solidified shell and the drawing-out time. At the time of finishing the drawing-out time and starting the stopping time, the pressure signal is transferred from the controller 50 to the driving circuit of the bending cylinder 35 and an impressing force from the bending cylinder 35 is increased to forcedly press the cooling blocks 22 to the mold 21, Air gap is removed and the molten metal 11 is sufficiently cooled. At the time of completing the stopping time, the reduced pressure signal is transferred from the controller 50 to reduce the impressed force from the bending cylinder 35. By this method, the flow on the solidified shell surface at the time of drawing out is not developed.

IPC: A61L9/01
Filed: 1987-12-24
Abstract: PURPOSE:To deodorize many kinds of malodorous components, by granulating a powdery mixture of activated clay and zinc salt. CONSTITUTION:A granular deodorant is prepared by a method wherein moisture is added to and mixed with a mixture of activated clay and zinc salt in an amount corresponding to about 50wt.% of the wt. of both of them and the resulting mixture of three components is molded under heating by a granulating extruder. The mixing ratio of activated clay and zinc salt is suitably set to a range of 99:1-50:50 on a wt. basis. As the malodorous components generated from household raw garbage or a toilet, nitrogen-containing alkaline substances such as ammonia or trimethylamine, sulfur-containing acidic substances such as hydrogen sulfide or mercaptan and neutral substances such as dinethyl sulfide or the like are designated. Since the above mentioned malodorous components correspond to either one of the alkaline substances or sulfur-containing substances, all of malodorous components can be deodorized by mixing activated clay and zinc salt.

Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To easily adjust a frequency after a crystal resonator has been sealed by jointing a transparent and flat lid formed of glass to a base substrate for sealing the crystal resonator. SOLUTION: This crystal resonator sandwiched by electrodes is jointed into the recessed part 23a of the base substrate 23, and seal glass 22 is jointed on the upper face of the outer peripheral part of the base substrate 23. Thus, the crystal resonator is sealed between the lid 21 and the base substrate 23. The frequency of the crystal resonator is inspected, and the frequency of the crystal resonator which requires adjustment is adjusted by having it irradiated with laser beams from the outer side of the transparent glass lid and cutting the electrode. Thus, the lid 21 seals the crystal resonator and the frequency is adjusted by using the laser beam from the outside via the transparent glass lid 21. Consequently, the yield of a final product is drastically improved.
