Title: Dry polishing wheel and its manufacture
Inventor: OKADA HIDEKI
IPC: B24D3/32
Filed: 1985-02-07
Abstract: PURPOSE:To form a wheel with its new abrasive grain surface continually appearing in accordance with polishing work and eliminate the necessity for dressing the wheel, by piling together a plurality of paper sheets, consisting of an abrasive grain, fibril made natural fiber and a binding agent, as an annular or circular sheet. CONSTITUTION:An abrasive grain, fibril made natural fiber and a binding agent are mixed in water, next after flock is generated by adding a flocculating agent, this slurry is made into paper in accordance with the normal method. In this way, the obtained paper sheet forms an annular or circular plate shaped sheet, and a plurality of these sheets are piled together, obtaining a desired dry polishing wheel. A web structure, consisting of this abrasive grain, fiber and the binding agent, is rich in elasticity and a relatively weak binding unit, and when the wheel performs polishing, the wheel, destructing its peripheral end surface with polishing and successively forming the new web structure with its abrasive grain surface appearing on the surface, eliminates the necessity for dressing the wheel.

Filed: 1991-02-18
Abstract: PURPOSE:To improve responsiveness at the time of stopping by changing over a target speed to a set low speed immediately without a sacrifice of decelerating time when a high-speed operation mode is changed over to a low-speed mode. CONSTITUTION:When an operator presses a winding operation push-button 5, the part between the COM terminal and the F/R terminal of an inverter controlling part 7 is cut off for a winding mode. After a constant time has passed, the part between COM terminal and an INC terminal is short-circuited for an inching mode.

Filed: 1992-02-10
Abstract: PURPOSE:To largely lower the min. load of a boiler, to utilize coal of a high fuel ratio and to produce powdered coal having wide particle size distribution by providing a definite distance between the top plate of a housing and the upper end of a rotary blade and providing an up-and-down movable adjusting cylinder from the top plate of the housing inside or outside the rotary blade. CONSTITUTION:In a vertical mill, by raising the lower end of an adjusting cylinder 15 above the upper end of a rotary blade 14, a part of particles circulating within the mill is discharged to the outside from a discharge pipe through the gap between the lower end of the adjusting cylinder 15 and the upper end of the rotary blade 14 even when the particles are rougher than the classification point in a classifier 13. The particles circulating within the mill are ground until they become finer particles because the classification point in the classifier becomes small by raising the number of rotations of the classifier 13. By this constitution, powdered coal with wide particle size distribution containing fine particles can be produced and stable combustion is achieved at the time of the min. load of a boiler or even in a boiler using coal inferior to combustion properties.

IPC: G05F1/44
Filed: 1993-02-12
Abstract: PURPOSE:To effectively suppress biased magnetization due to an imbalanced voltage applied to an inverter unit with an inductive load. CONSTITUTION:If the load current of an inverter circuit 200 is imbalanced to the positive or negative direction due to the imbalance in the output voltage, a biased magnetization detecting circuit 500 outputs a signal. A minimum dead time setting device 700 issues a setting signal corresponding to the optimum dead time length. This signal is added by an adder 600 to a value detected by the biased magnetization detecting circuit 500. When a biased magnetization occurs, the adder 600 issues a signal to set a dead time corresponding to the amount of biased magnetization and a PWM waveform generator 800 sends to a switching element a drive signal with a dead time corresponding to the setting signal from the adder 600.
