Title: Surface treatment method
Inventor: KOMORI MASANOBU
IPC: C23C8/34
Filed: 1982-04-14
Abstract: PURPOSE:To reduce the generation amount of scale due to oxidation, by a method wherein the surface of austenite type stainless steel subjected to nitridation treatment is subjected to oxidation treatment and a first and a second oxide layers are removed to leave a third oxide layer. CONSTITUTION:After the surface of the ferrous metal of 18Cr-8Ni type austenite type stainless steel is subjected to nitridation treatment, the treated steel is subjected to high temp. oxidation treatment to form a first oxide layer mainly comprising Fe2O3, a second oxide layer comprising Fe3O4 reaching a depth of 0.02mm. from the surface thereof and a third oxide layer of alpha+FeO+Cr2O3 in a depth of about 0.07-0.08mm.. The film of this third oxide layer does not advance further in oxidation because of the presence of Cr2O3. Therefore, by processing and removing the first and the second oxide layers to leave the third oxide layer slow in the advance of oxidation, the generation of oxide scale is suppressed. This method is suitable for the surface treatment of the valve stem and the bush of a steam turbine main valve required in always holding a predetermined gap.

Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to exactly, easily and completely pack a plating material into grooves having a depth and width of low values by forming thin films by an electroplating method within the groove parts formed on a substrate surface. SOLUTION: Secondary line grooves 26b are formed opposite to primary line grooves 26a by grinding using a magnet T. The secondary line grooves 26b are formed in such a manner, by which the line grooves 26 are completed. Conductive ground surface films 32 having thin films 31 remaining only on the bases B thereof are formed. An electrode jig 35 is then mounted on the substrate 21 and the electroplating method is executed by using the ground surface films 32 as cathode electrodes. Cu which is the conductive plating material is thereby grown on the ground surface films 32. The Cu is thus packed into the line grooves 26. The Cu deposited on the line grooves 26 is subjected to polishing for flattening, by which terminal junctures are completed.

Title: Branch insertion system to direct relaying
Inventor: MOMO NIJIROU
IPC: H04J1/10
Filed: 1978-05-25
Abstract: PURPOSE:To avoid the effect to other directions due to the decrease in signal, by using the oscillator having the frequency equivalent to the signal difference between the No. 2 and No. 3 directions, when the No. 1 to No. 2 signal is less than a given value. CONSTITUTION:When the signal f1 toward the No. 1 direction decrease, the discrimination circuit LOG1 selects the switch SW1 to 1-2 and the switch SW2 to 2-3. Thus, the signal in frequency f3' is produced at the output of the mixer MIX3 and it is delivered as the signal toward the No. 3 direction. When the signal f2 is decreased, similarly the switch is selected to 1-1 and 2-2 to produce the signal of f3' at the output of the mixer MIX3. Thus, when the signal toward the No. 1 or No. 2 is decreased, the signal of the shift oscillators SFO3 and SFO4 can deliver the signal  from normal direction to the No. 3 (f3) direction.
