Title: Treatment of dust-containing water of molten iron pretreatmemt furnace
Inventor: INA MASAKI
IPC: B01D21/01
Filed: 1994-04-11
Abstract: PURPOSE:To efficiently apply flocculation treatment to independent treatment dust-containing water by adding an acrylic ester type cationic polymeric flocculant whose colloid equivalent is specific to the dust-containing water of a molten iron pretreatment furnace and adjusting the pH thereof to a specific value before solid-liquid separation. CONSTITUTION:The exhaust gas of a molten iron pretreatment furnace is guided to a wet dust collector and brought into contact with water to collect dust in the gas to form dust-containing water. In the case of the treatment of this dust-containing water, an acrylic ester type cationic polymeric flocculant whose colloid equivalent at pH4.0 is 0.1-3.0meq/g is added to the dust-containing water. Thereby the pH value is regulated at 5-8.9 and then solid-liquid separation is performed. As the cationic polymeric flocculant, for example, an alkylaminoalkyl (meth)acrylate/(meth)acrylamide copolymer is used. By this constitution, floc good in sedimentation properties is formed and solid-liquid separation is made easy.

Title: Method for cleaning surface of aluminum material for cap
Inventor: TOYOSE KIKURO
IPC: C23G5/00
Filed: 1987-04-20
Abstract: PURPOSE:To easily clean the surface of an Al material for caps and to improve the adhesion to a paint film by treating the material with a soln. type degreasing agent to remove rolling oil and by activating the surface by corona discharge. CONSTITUTION:An Al material for caps obtd. by cold rolling is treated with a soln. type degreasing agent such as an alkali-, acid- or solvent-based degreasing agent to reduce the amt. of rolling oil sticking to the material <=1mg/m<2>. The material having the very amt. of residual oil is further treated by corona discharge. Conditions during the corona discharge are properly selected so as to decompose and remove the residual rolling oil and to reduce the angle of contact water to <30 deg., preferably <=about 20 deg.. By the corona discharge, the surface of the material is activated. Thus, the adhesion of the material to a paint film is improved and the peeling of the paint film during subsequent necessary working such as drawing is prevented.

Title: Magnetostatic wave oscillator
Inventor: AOKI IKUO
IPC: H01P1/215
Filed: 1991-04-26
Abstract: PURPOSE:To provide a magnetostatic wave oscillator enlarging the oscillation bands while keeping satisfactory phase noise characteristics. CONSTITUTION:A magnetostatic wave delay line composed of an input/output transducer and a magnetostatic wave propagation medium 1 and an amplification circuit 7a constitute an oscillation loop, and in the magnetostatic wave oscillator of which the oscillation frequency is changed by a magnetostatic field corresponding to a control input VC for setting frequency, the saturation level of the amplification circuit 7a is controlled by the output current of a variable constant current circuit 16 corresponding to the control input VC. The saturation of a magnetostatic wave delay line is prevented by reducing the saturation level of the amplification circuit 7a rather than that of the magnetostatic wave delay line on the low frequency side corresponding to the control input VC, and the phase noise characteristic is improved. Further, the upper limit frequency of oscillation is enlarged by increasing the saturation level of the amplification circuit 7a on the high frequency side.

Title: Case structure of wrist watch
Inventor: NAGATA HIROMICHI
IPC: G04B37/16
Filed: 1985-05-10
Abstract: PURPOSE:To improve workability and yield by performing the plating to a sintered hard case so that its size is a little larger than a thin plate fixing part, and on the other side, performing the plating to the whole surface, and using a thin plate whose terminal expansion coefficient is <=12.0X10<-6>/ deg.C. CONSTITUTION:A thin plate 4 is tack-welded to a thin plate fixing part 2 by a projection welding 5. In that case, the thin plate 4 is sloped down so as to descend as it goes toward the outside direction of the wrist watch, therefore, after the tack-welding, a sintered hard case 1 is turned inside out and a brazing filler material 6 is placed in the vicinity of the fixing part to which the case 1 and the thin plate 4 have been tack-welded. In this case, the section of the brazing filler material 6 is formed so that a part of the brazing material 6 contacts directly to a plating part 3 of the case 1. Accordingly, since a part of the brazing filler material contacts to a part of the plating part 3, a brazing metal can be called in, and brazing can be executed satisfactorily by the brazing filler material of the minimum quantity. Also since a thermal expansion coefficient of the thin plate 4 is <=12.0X10<-6>/ deg.C, the workability in case of brazing the thin plate 4 to the case 1 is improved, and the yield can be improved.
