Title: Production of spherical pearlite
Inventor: KATAOKA NOBUHIRO
IPC: C01B33/26
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To produce a spherical pearlite low in water absorption and excellent in fluidity or the like by crushing a natural vitreous rock and controlling the particle size, preheating it to control water content, adding a prescribed quantity of a high m.p. fine powder, and subjecting to foaming firing. SOLUTION: The natural vitreous rock (e.g. pearlite) is crushed under controlling the particle size. Next, the resultant rock particles are preheated at a lower temp. than the softening point to control water content to 0.1-2wt.%. Then, 30-200vol.% high m.p. fine powder (e.g. fly ash) having preferably 10-100μm particle diameter is mixed with the rock particles and foamed and fired at 900-1300 deg.C. As a device for foaming and firing, a rotary kiln or an electric furnace is suitable. Next, the produced pearlite is separated from the high m.p. fine powder by a vibrating screen, a wind screen or the like to obtain the spherical pearlite. The resultant pearlite has closed pores, small unevenness on the surface, excellent fluidity at the time of making mortal and is particularly suitable for application to building materials.

Title: Power supply circuit
Inventor: SHINTANI PIITAA
IPC: H02J1/00
Filed: 1992-12-25
Abstract: PURPOSE:To realize a power supply circuit for which the duration of life of its filament can be lengthened. CONSTITUTION:When power is turned on for a flyback transformer FBT, then an output voltage Vout changes; and when a level which makes the output voltage Vout equal to a stationary value is changed to 100% level, a duration from power turning-on to 50% level is limited by a Zener diode Zd provided by transistor FET, by which the occurrence of inrush current can be prevented. Thereafter, the channel resistance of the transistor FET gradually decreases as a result of charging to the capacitor C and the output voltage Vout increases slowly in response to the above and shifts to a stationary value (100% level). That is, the power supply circuit provided in the heater circuit operates so as to restrict the output current until changing from power turn-on to stationary value. By doing this, an inrush current which occurs during power turn-on and a sudden current cut due to power supply breaking can be prevented and the duration of life of the filament can be lengthened.

Title: Membership function generation device
Inventor: O MASANARI
IPC: G06G7/12
Filed: 1991-12-28
Abstract: PURPOSE:To prevent the shape of a membership function from varying even if a source voltage varies. CONSTITUTION:A membership function generating circuit generates a membership function by assigning a reference current I0 according to the differences between reference voltages VL1 and VL2 and an input voltage VIN. A constant current source which does not depend upon the source voltage is used as a reference current-source C1 and even if the source voltage varies between +VCC and -VEE, the reference current I0 does not vary, so the shape of the membership function does not vary. The arithmetic precision of a fuzzy system is improved. Then this device is applicable to other systems which differ in source voltage.

Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To control the amount of developer flowing down by gravity from a developer tank to a developer reservoir to be in a desirable condition by regulating the intrusion of air into the developer tank by the developer in the developer reservoir. SOLUTION: A developing unit 110 located at a developing position is in posture to supply the developer 1104 of a developer cartridge 1102 to a developing device 1103 by making the developer 1104 flow down by a proper amount. A developing unit 140 passed through the developing position recovers a part of the developer 1404 supplied to a developing device 1403 to a developer cartridge 1402 by making it flow backward. In order to make the developer 1104 flow out from the cartridge 1102, it is necessary to make air flow into the cartridge 1102. The outflow of the developer 1104 in the cartridge 1102 caused by the backflow of the air stops when the liquid level of the developer 1104 in the developer reservoir 1109 rises to a liquid level regulating wall and the backflow of the air is stopped. Therefore, the liquid level of the developer is nearly equal to the lower end position of the liquid level regulating wall.
