Title: Formation of compound thin film and device for executing this method
Inventor: NISHIMOTO KEIJI
IPC: C23C14/32
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To form a compd. thin film at a relatively low temp. by irradiating a substrate consisting of the other of compd. constitution elements with an ion beam of the one metal among the compd. constitution elements and irradiating the substrate alternately or simultaneously with the ion beam of the one metal among the compd. constitution elements and the ion beam of the other metal. SOLUTION: The substrate is irradiated with the ion beam of energy from several eV to several 1000eV, by which the part near the surface of the substrate 7 and the ion beam are brought into reaction and the compd. thin film is formed. In such a case, only the compd. thin film of about several 10nm thickness is formable. When the compd. thin film thicker than the same is going to be formed, the substrate 7 is irradiated alternately or simultaneously with the ion beam of the compd. constitution element of the substrate constitution element and the ion beam of the compd. constitution element different from the substrate constitution element to form the compd. thin film. The substrate 7 is recommended to be kept heated to the temp. at which a chemical reaction is accelerated for added convenience. The formation of the film at a relatively low temp. of <=50 deg.C is possible.

Title: Highly plastic alumina paste and its production
Inventor: ONO AKIRA
IPC: C04B35/10
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To obtain a highly plastic alumina paste useful as a ceramic stock by incorporating alumina particles with agar-agar. SOLUTION: This highly plastic alumina paste is obtained by melting agar powder under boiling followed by cooling to form agar gel which is then kneaded with alumina particles; alternatively, by adding alumina particles to an aqueous solution of agar powder which is melted under boiling in advance, followed by cooling the system to effect coating the alumina surface with agar-agar followed by dehydration; wherein it is preferable that the agar-agar to be used as a starting material is >=5 g/cm2 in jelly strength, and the agar content of the final alumina paste is 0.5-10 wt.%.  This alumina paste obtained by mixing (kneading) process is capable of controlling its pore size depending on its gel size, therefore being advantageous for making porous forms; whereas another version of this alumina paste obtained by coating process is hard to produce pores because the agar-agar as binder uniformly and extremely thinly adheres to the alumina, therefore affording a dense sintered compact, dense/high- density molded form or molded form with controlled pore size. The above method for producing this alumina paste is effective in cost reduction and operability improvement.

Filed: 1986-12-06
Abstract: PURPOSE:To impart excellent corrosion resistance and pitting resistance to the title steel sheet by underplating a Zn-Fe alloy incorporated with the specific amt. of oxide particles on the steel sheet surface, and overplating a Zn-Fe alloy thereon. CONSTITUTION:A Zn-Fe alloy contg. 10-30wt% Fe and 0.005-5wt% >=1 kind among silica, alumina, titanium oxide, magnesia, chromium oxide, and zirconium oxide is electroplated on the surface of a steel sheet as the lower layer.

The deposition amt. of the lower plating is controlled to about 10-50g/m<2> per face, and the deposition amt. of the upper plating is preferably adjusted to about 0.5-10g/m<2> per face. Since eutectic oxide particles are dispersed in the lower layer of the double-layer electrodeposited steel sheet, formation of non-growing type corrosion products is accelerated by the oxide when corrosion proceeds to the lower layer, and the progress of corrosion into the inside is prevented.

Title: Convergence correction circuit
Inventor: SUZUKI MANABU
IPC: H04N9/28
Filed: 1990-10-31
Abstract: PURPOSE:To improve a convergence correction function and to reduce cost by applying voltage for convergence correction respectively to the primary winding wires of two correction voltage transformers equipped with two secondary winding wires having the equal number of primary and secondary winding wires. CONSTITUTION:In the connection of the secondary winding wires of two correction voltage transformers (dynamic convergence transformers DCT-4:DCT-5) equipped with two secondary winding wires having equal number of primary and secondary winding wires, the common mode connection and the reverse mode connection of the secondary winding wires of respective transformers are made to superimpose each output through a clamp circuit to horizontal still convergence electric potential (H.STAT electric potential) VD. In short, since convergence correction voltage CV3 is generated by the output addition of two power amplifiers 3 and 4, the output of each amplifier can be halved and the number of winding wires of the secondary winding wire of one transformer can be reduced. Thus, the DCT can be reduced to two without deteriorating the correction function of misconvergence.
