Abstract: PURPOSE:To manufacture high-reliability multilayer printed boards by forming a copper oxide layer on the surface of an inner copper foil layer in an inner circuit board before the formation of a circuit patter, and grinding the copper oxide layer mechanically into a this and rough copper oxide film. CONSTITUTION:Patterning of a glass-cloth base epoxy resin double copper-clad laminate is performed by circuit formation by the use of UV hardening resin, and it is used for an inner circuit board. Next, this is dipped in an aqueous solution of H2O2 34g/l and H2SO4 46g/l for two minutes, and the surfaces are made rough by etching. After that, it is cleansed with dilute hydrochloric acid. Next, the copper-clad laminate is washed with water sufficiently and dipped in an aqueous solution of NaClO4 30g/l, NaOH 25g/l, Na2PO4.2H2O 5g/l; temperature 85 deg.C for two minutes, and a copper oxide layer 3 is formed and washed with water. Next, the copper-clad laminate having the copper oxide layer is ground with a #600 buff, and washed with water sufficiently. After being dried, it is baked at 105 deg.C for 30 minutes to make an inner circuit board 2.

Title: Oil separator
Inventor: KOIKE TADASHI
IPC: B01D17/02
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To provide an oil separator in which defective drainage is detected early. SOLUTION: The oil separator has a separator casing consisting of an inflow port 4 for water containing oil, an accumulating part 3, an outflow part 5 and a pressure equalizing port 14. In the accumulating part 3, a vertically long float 6 is arranged so as to be freely movable up and down. Just below the vertically long float 6, a valve seat member 12 provided with an outflow port 5 is fitted. The pressure equalizing part 14 is provided with a see-through part 24 successively, and the see-through part 4 are provided with plural windows inside which glass tubes 27 are arranged. Water containing oil that has flown in the accumulating part 3 is separated into water and oil which are accumulated in the upper and the lower parts respectively. When the water level reaches a prescribed position, the float 6 floats and only the water is discharged from the outflow port 5.  When the float 6 cannot float for some reason and the water cannot be discharged from the outflow port 5, the water level in the accumulating part 3 is raised and furthermore the water level in the see-through part 24 is also raised. By visualizing a rise in the water level in the see-through part 24, defective drainage is detected early.

Filed: 1981-02-16
Abstract: PURPOSE: To prepare high purity SiF 4  having extremely low hexafluorodisiloxane content, by maintaining the concentration of sulfuric acid used as a reaction medium above a specific level in the catalytic reaction of SiO 2  with HF in the presence of sulfuric acid.  
     CONSTITUTION: Amorphous or crystalline SiO 2  is dispersed in sulfuric acid of ≥80% concentration, and hydrofluoric acid or anhydrous HF is added to the dispersion to generate SiF 4 . The sulfuric acid is diluted as the reaction proceeds with H 2 O produced as a by-product of the reaction. Accordingly, the concentration is maintained to ≥80% by a proper means, e.g. by adding 98% sulfuric acid or fuming sulfuric acid to the reaction system in the course of the reaction. High purity SiF 4  having extremely low hexafluorodisiloxane (SiF 3 -O-SiF 3 ) content and suitable for the manufacturing of an amorphous Si layer for solar battery, can be obtained by the process.

Title: Frier
Inventor: KOBAYASHI TOSHIHIRO
IPC: A47J37/12
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To restrict aging of oil by speeding up a temperature rise of the oil in a cooking zone with a simple structure. SOLUTION: When an inclined surface 10a of an oil tank 10 is heated by a burner 31, oil rises in temperature near the inclined surface 10. All of the high temperature oil heated directly flows to a cooking zone from an opening 16 for outflow at an upper part of a guide plate 14 so that the temperature of the oil in the cooking zone rises quickly. The oil in the intermediate zone at a lower part of the cooking zone is harder to rise in temperature than the oil in the cooking zone thereby restricting aging of the oil.
