Title: Treatment of exhaust gas
Inventor: YAMADA SHINICHI
IPC: B01D53/60
Filed: 1993-09-10
Abstract: PURPOSE:To achieve desired desulfurization and denitration capacity from the initial operation stage of the treatment of an exhaust gas even when a carbonaceous catalyst of low quality is used by introducing oxygen containing gas into a regenerator before the start of the operation of desulfurization and denitration treatment to oxidize and activate the carbonaceous catalyst. CONSTITUTION:An exhaust gas containing sulfur oxide and nitrogen oxide is introduced into a moving bed reactor packed with a carbonaceous catalyst to be subjected to desulfurization and denitration treatment in the coexistence of NH3 while the carbonaceous catalyst deactivated by the contact with the exhaust gas is heated and regenerated in a regenerator 6. In this treatment of exhaust gas, oxygen-containing gas is introduced into the regenerator 6 before the start of the operation of desulfurization and denitration treatment to oxidize and activate the carbonaceous catalyst 4. For example, the carbonaceous catalyst 4 is stored in the storage area 11 of the regenerator 6 to flow down to a mixing area 12a to pass through a heat transfer pipe 13 and heated to desired temp. (e.g. 100-400 deg.C) suitable for oxidation by heating gas and the heated catalyst is sent to a separation area 14a and discharged from the lower part of the regenerator 6 to be circulated to the reactor.

Abstract: PURPOSE:To obtain parts having a uniform surface film and high reliability in a process for production in which compaction-molded parts of silicon iron powder are annealed after sintering by providing a stage for removing the silicon dioxide on the surface of said parts after the annealing stage. CONSTITUTION:The silicon iron powder 1 is pressed by molds and molded to desired parts in a compaction molding stage 2 and the molded parts are sintered under heating in a sintering stage 3.

The SiO2 generated on the surfaces of the sintered parts in the sintering stage and annealing stage is removed by using a blasting method in which emery 10 is blasted at a high speed from a high pressure nozzle 11 or by using a soft cloth in an SiO2 removing stage 7. The SiO2 is thus removed without exerting working strain to the sintered parts and the uniform surface film is formed on the sintered parts in a surface finish treating stage 6 without the deterioration of the magnetic characteristics.

Filed: 1985-10-11
Abstract: PURPOSE:To make it possible to make repeating operation when modulating system is either analog modulation or digital direct modulation by providing a clock detecting circuit, an analog modulating circuit and a switching circuit that switches digital direct modulating system and analog modulating system. CONSTITUTION:Digital signals outputted from a digital conversion circuit 5 become transmission base band signals and inputted to a switching circuit 10. Signals outputted from an analog modulating circuit 9 are also inputted to the switching circuit 10.

As the result of judgement, if there is clock component in received input signal, the switching circuit 10 connects a base band conversion circuit 6 and a modulator 7 and operates to make transmission signals of digital direct modulation as the signal is that of digital direct modulating system. When there is no clock component in received input signals, the switching circuit 10 connects the analog modulating circuit 9 and the modulator 7 and operates to make analog modulated transmission signals as the signal is that of analog modulating system.

Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a slide core which moves back and forth horizontally without causing friction with an edge part in clamping the top force of a molding die and thereby prevent the edge part from becoming deflected or deviated and also prevent a urethane foam from leaking from an area near the edge part. SOLUTION: A core Xb is set in the top force 5 of a molding die and a skin material Xa is set in the bottom force 3. Next, a slide core 21 is moved forward under this state and the outer face of an edge part 9 is positioned by causing it to come into contact with a first contact face 23 and retaining the outer face of an edge part 9. Then a raw material for a urethane foam Xc is injected into the back face of the skin material Xa. After that, the top force 5 is caused to descend and at the same time, the slide core 21 is caused to move backward to clamp the forces. Thus the edge part 9 is positioned by retaining it with the projecting part 13 of the core Xb and the outer edge of the core Xb is sandwiched between the second contact part 25 of the slide core 21 and the top force 5.  Further, the raw material for the urethane foam Xc is caused to foam between the core Xb and the skin material Xa by the mold temperature of a molding die 1, so that an instrument panel X which partially has a pad part 7 with the urethane foam interposed between the core Xb and the skin material Xa is integrally molded.

Title: Production of quartz glass based optical waveguide
Inventor: KONISHI SHIGERU
IPC: C03B19/12
Filed: 1994-09-21
Abstract: PURPOSE: To obtain a high quality quartz glass based optical waveguide by using a sol solution consisting of a mixture of a sol obtained by adding another metallic alkoxide to silicone alkoxide to hydrolyze, and a dispersion of a fine powdery metallic oxide. CONSTITUTION: The sol solution of a glass raw material is prepared by adding 1-10wt.% dopant such as another metallic alkoxide to silicon alkoxide, hydrolyzing to form a sol solution and mixing the dispersion of 3-20wt.% fine powdery metallic oxide such as SiO2 per total alkoxide. The sol solution is applied on a quartz substrate combining a lower clad layer, gelated, dried and heated to form a porous glass body and a quartz glass laminated film for a core is formed by transparently vitrifying the porous glass body under heating at >=1000 deg.C. The high quality optical waveguide is obtained by transferring an optical waveguide pattern thereon, forming a core layer by reactive ion etching and further forming an upper clad layer having lower refractive index than that of the core layer thereon by using a sol solution for a clad, from which the dopant is removed.

Title: Method for preventing bond strength of organic adhesive from being lowered
Inventor: ZAMA MASATO
IPC: C09J5/00
Filed: 1982-12-27
Abstract: PURPOSE:To prevent the bond strength in the bonded part of a member bonded by org. adhesive from being lowered with time, by cathodically inhibiting, the corrosion of a metallic member in a corrosive soln. such as sea water. CONSTITUTION:The potential in the bonded part and its neighborhood of metallic members or alloy members (e.g. nickel sheet or steel sheet) bonded by an org. adhesive (e.g. epoxy paint) in a corrosive soln. such as sea water, is kept at a potential lower than the spontaneous electrode potential of the bonded part of the member. Usually, it is desirable to keep the potential at -200- -800mVS.C.E (saturation calomel electrode reference). In this way, the bond strength in the bonded part of the member bonded by the org. adhesive is prevented from being lowered with time.
