Title: Method for cracking of hydrocarbon and catalyst used therein
Inventor: ROBAATO BAATEKU
IPC: C10G11/05
Filed: 1988-09-13
Abstract: PURPOSE: To lower a harmful action on a catalyst because of a metal contaminant by performing catalytic cracking of a hydrocarbon supply material in the presence of a solid composition including a specific metal constituent and a catalyst containing a molecular sieve.  
     CONSTITUTION: In catalytic cracking of a hydrocarbon supply material carried out in a catalytic area in the presence of a solid composition including a catalyst, which contains a molecular sieve and can promote cracking of the hydrocarbon supply material under an efficient condition for decomposing it into constituents with lower boiling points, this catalytic cracking is carried out in the presence of at least one kind of metal constituent selected from barium, chromium, zirconium, and tin in addition to the catalyst. The metal constituent may exist in a particle other than a solid particle containing the catalyst, however, the metal constituent is favorably contained in the solid particle. For a useful molecular sieve, a zeolite series molecular sieve or zeolite, a non-zeolite series molecular sieve or NZMS, and a mixture of them are available.

Title: Suction sump for pump
Inventor: KANEKO MASATOSHI
IPC: F04B53/16
Filed: 1994-09-22
Abstract: PURPOSE: To randomly, freely, and easily set water pumping start/stop levels so as to comply with any water levels by forming a bored part having a specific inside diameter around a suction pipe of a pump having a suction pipe in a suction sump having a free surface. CONSTITUTION: When suction water level H is lowered during operation of a pump(P), inflow water drops as a waterfall in a bored part 1 in the adjacent of a bell mouth M. And it is sucked from the bell mouth, along with air rolled up in the basin part of the waterfall, namely, the bottom part 1a of the bored part 1 so as to stop water pumping. When the water level is raised, water pumping is restarted. Therefore, operation of the pump(P) can be continued regardless of suction water level. When the inside diameter(d) is double the suction pipe diameter(D) or less, generation of underwater vortex water is uncertain, water flow collides against the pump(P) so as to form inferior waterfall, and in the case of triple or more, air roll-up is inferior so that the inside diameter(d) of the bored part is set to two or three times of the suction pipe(D).

When the rack 8 is pulled out forwardly, a knob 23 of an inner cover 20 is released from an engagement part 22, and pulled out in the state where the inner cover 20 is placed in an inner pot 17. Therefore, the engagement of the rack 8 can be released only in the case when the cover body 18 is at the position suitable for the pulling-out of a pot body 15, and when the cover body 18 is at an improper position, the rack 8 is held in the engagement state, and the cover body 18, pot body 15, and the peripheral parts are prevent from being broken.

IPC: H02G15/02
Filed: 1993-08-20
Abstract: PURPOSE:To enhance aseismatic strength and mechanical strength that low cost by forming an epoxy seat of an epoxy resin and providing a lower flange part. CONSTITUTION:The upper part 63 of an epoxy seat 6 having a through hole 61 in the cable insulator 1 is set in a bushing 3 while abutting on the outer periphery of a premold insulator 5 and the inner space of the bushing 3 is filled with an insulation compound 4.

Title: Granule detector for agricultural machine
Inventor: HIRAYAMA HIDETAKA
IPC: G01V9/00
Filed: 1988-09-12
Abstract: PURPOSE:To eliminate a harmful influence caused by unnecessary secondary vibrations associated with vibrations produced in a granule detector so that the measuring accuracy of the detector can be improved by outputting signals only when the rise of the vibrations is detected. CONSTITUTION:Signals SI outputted from the granule detector 1 in accordance with the detection of granules are outputted and subjected filtration and half- wave rectification 2 and become signals S2. The signals S2 are compared 3 with a 1st reference value supplied from a clip circuit 4 and, as a result, a programmable uni-junction transistor 5 which is a switching element is turned on at the rising time of the signals S2. Then a PUT 5 is turned off after the capacitor C1 of a charge and discharge circuit 5 is quickly charged. The output signal S4 of the circuit 5 is compared 6 with a 2nd reference value decided by resistances R2 and R3 and, at the same time, superimposed upon the 1st reference value. Since an output signal S5 which detects the rise of vibrations produced in the detector 1 only is obtained from a comparator 6, the influence of secondary vibrations associated with the vibrations can be eliminated and the measuring accuracy of the detector 1 can be improved.
