Abstract: PURPOSE:To obtain quickly and easily a reaction record even with FCC consisting of residual oil and other heavy gravity hydrocarbons as the raw material by putting the raw material together with a catalyst into a vessel then heating up the material to the Curie point to effect the catalytic cracking reaction of the raw material. CONSTITUTION:Gaseous nitrogen is fed through a feed pipe 1 and a cock 2 to a sample pipe 31 of a cracking furnace 3. The resultant product of cracking of a sample 32 is fed to a column 4. The gas flowing out of the column 4 is fed through the cocks 2 and 5 to a molecular sieve 6. H2 and C1 are detected by a heat conductivity type detector 7. The cock 2 is changed over after detection of H2 to block the column 4 and to form lines 2, 5, 6, 7, 8, 9. The molecular sieve 6 is properly heated up and C1 and C2 are analyzed by detectors 7 and 9.

The column 4 flows out the gases in order of the b.p. The distillation characteristic of C<+>3 fraction is determined from the retention time of the peak area obtd. by the detector 9. As a result, the catalytic cracking reaction ends in a short period.

IPC: G01N30/64
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To perform continuous efficient ionization while heightening rigidity against a force from inside and suppressing deformation, by providing a tip surface with a curved surface to be recessed most at its approximate center so as to be bulged to the inside of a nozzle and boring a gas injection opening. SOLUTION: An end face plate 16 is sandwiched between the circumferential surface of the end of a nozzle main body 11 and a fixing nut 15 via a flat circular gasket 14. The end face plate 16 is formed of, for example, metal such as nickel and is provided with a spherical surface with a required curvature in a shape bulged to the inside of the nozzle body 11. A gas injection opening 13 of predetermined diameter is bored at the approximate center, i.e., the most recessed part of the end face plate 16. Upstream gas pressure is relatively extremely higher than downstream gas pressure with respect to both sides of the tip surface of the nozzle, and a large force is exerted on the tip surface from the inside of the nozzle.  In spite of this, as the tip surface is bulged to the inside of the nozzle, the tip face has a larger strength against a force from the inside than in the case with a flat tip surface and is scarcely deformed.

Filed: 1991-02-20
Abstract: PURPOSE:To obtain a digital pulse width converting circuit which can drive the transistor in a three-phase transistor inverter in proportion to a current command by stopping the operation of an up/down counter for a predetermined time. CONSTITUTION:When the counts of counters 11, 12 exceed a positive threshold, output CM of a comparator 16 goes H. When a maximum count is reached, the counter 12 outputs a ripple carrier from a terminal RC. Consequently, the counters 11, 12 begin down counting and when the count drops below the positive threshold, the output CM goes L. A signal DR is obtained from the output CM and an output from a NAND gate 20 and a transistor Q1 is turned ON by an output from an ON delay circuit 25 comprising a pulse with a rising delay DL during H level interval of the signal DR. Similarly, an ON delay circuit 26 turns a transistor Q4 ON with a pulse having the rising delay DL during L level interval of the signal DR.
