Title: Magnification controller in scanning electron microscope, etc.
Inventor: HIRATA YOSHIHIRO
IPC: H01J37/22
Filed: 1979-12-28
Abstract: PURPOSE:To control magnification without degrading the S/N ratio of a circuit by compensating the reduction component of a deflection current which is caused by improving the degradation of the S/N ratio due to an attenuator with a variable resistance circuit, adjusting the gain of a voltage amplifier. CONSTITUTION:The maximum and minimum values of the output signal of a scanning signal generator 1 which is attenuated by an attenuator 6 to enlarge magnification are detected by the maximum value detector 8 and the minimum value detector 9. The absolute value as the difference of these two values is calculated by  an absolute value detector 10 and sent to a hysteresis circuit 11. The hysteresis 11 compares a preset reference value with the output value of the absolute value detect or 10. It increases also the resistance value by sending a command to a variable resistance circuit 4 and the gain of an amplifier by sending it to a voltage amplifier 7.  This can improve the degradation of the S/N ratio due to the attenuator, compensate the reduction of the deflection current which is applied to an electron beam  deflection coil 3, and control a high magnification without degrading the S/N ratio  of the circuit.

Title: Method of controlling oil combustion on fluidized bed and generation plant executing said method
Inventor: NIKORASU BAAKAA
IPC: F23C10/00
Filed: 1989-07-05
Abstract: PURPOSE: To obtain a uniform temperature distribution in a bed by supplying oil in the form of water/oil emulsion to the bed. CONSTITUTION: Oil emulsion contains 4-50% of water, 0-2% of emulsifier, and the remainder of oil. When oil fuel is supplied the form of water/oil emulsion to the bottom 11 of a combustor 10, water contained in a fuel drop 2 delays heating and emission of volatile substances. The fuel 2 spreads into the bed 11 and emits volatile substances upon elapsing some time while the water evaporates to blow off the fuel drop 2 to produce a small drop 2a. Consequently, the fuel is dispersed and it is not deposited on the bottom 13 of the combustor 10. Subsequently, solid coke particles 4 are formed, dispersed into the bed 11 and burnt. When the fuel drop is heated in a region 23 around a nozzle, volatile components are volatilized while the water is evaporated and the fuel drop 2 begins to be decomposed. The water disperses the fuel well to enlarge the combustion area 16.  Combustion takes place uniformly in the bed and a uniform temperature distribution can be attained.
