Abstract: PROBLEM TO BE SOLVED: To almost eliminate exhaust of sludge with excellent strength through a great amount of fly ash is used by a method wherein specific amounts of cement and fly ash are used. SOLUTION: 60-400 kg/m<3> of fly ash is used with 200-500 kg/m<3> unit cement amount. Those are charged into a shuttering, and centrifugally molded by rotating. The centrifugal force is, for example, 1-5 G initial speed for 1-4 min, 5-15 G middle speed for 1-4 min, and 15-35 G high speed for 1-4 min. Thereby, inorganic impalbable powder (cement and fine aggregate) and sludge in squeezed out concrete are integrated, and affixed onto an inner peripheral surface of a hollow part of the concrete formed body (a slag layer). A ratio of a product thickness occupied by the slag layer is about 15-35%. A great amount of fly ash can be used thus, concrete sludge to be exhausted in manufacture of the formed body is made nil, and excellent strength can be obtained.

IPC: G01N27/409
Filed: 1994-05-11
Abstract: PURPOSE:To increase the detection output under high temperature while enhancing adhesion of an oxidation catalyst layer by specifying the firing temperature range of oxidation catalyst. CONSTITUTION:A pair of Pt electrodes 2, 3 are printed using a Pt paste onto the surface of a ZrO2 substrate stabilized by an oxygen ion conductive solid electrolyte, i.e., Y2O3. Lead wires 5, 6 for taking out the sensor output are then printed using an Au paste from the electrodes 2, 3 and the entirety is fired at about 900 deg.C. Alumina powder impregnated with about 1.5wt.% of Pt is mixed with an organic solvent, a binder, and a surfactant to produce a paste which is then printed while covering one electrode 3 to form an oxidation catalyst layer 4. When the catalyst layer 4 is fired at 800-1000 deg.C, sensor output is increased and the catalyst activity is substantially prevented from lowering due to growth of catalytic grains.

Title: Time-of-fiight mass spectrometer
Inventor: SAKURAI TATSU
IPC: H01J49/40
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To improve resolution without impairing detecting sensitivity of an ion by flying the ion on a revolving path. SOLUTION: A pluse-like ion from an ion source 24 is accelerated by constant voltage to proceed to a ring-shaped revolving path 10 by a deflection electrode 28 so as to get on the revolving path 10 by an incident electrode 30 or 50 operating in synchronism with the incidence. For example, the ion revolving in the revolving path 10 by six sets of toroidal type sector electric fiels 12, 14, 16, 18, 20, 22 is completely corrected in a flying time difference at half round time by the converging action of the sector electric fields, and is returned to a central path to eliminate the flying time difference at one round time, and returns again to the same point to continue to revolve without diverging by taking the same path in a revolution on and after second time.  After revolving by the target number of times, the ion is taken out of the revolving path by operation of an emitting electrode 32 or 52 to measure time up to a detector from pulse operation of the ion source 24 by a TOF measuring circuit 40. Since the sector electric fields are used in this way, there is the triple converging action on a time space to prevent scattering of ion beams.
