Filed: 1981-05-14
Abstract: PURPOSE:To measure and display an etching depth of a sample under test concurrently  with a mass analysis of a measured element during measurement of depth and direction  distributions of the density of impurities. CONSTITUTION:Primary ions generated by a duo-plasmatron are scanned electrically  and radiated on a sample 2, which is etched in a rectangle with optional sizes. A  Michelson interferometer is utilized as an optical system to measure the etching depth.  A semiconductor laser capable of generating a light which is subject to interference is  used as a light source. A beam from the light source 5 is split in two directions by  means of a semitransparent mirror 7, then one of them, as a reference light, is reflected  by a reflecting mirror 9, again going through the semitransparent mirror 7, and is converged on a light receiving face of a light detector 12.

IPC: B01D53/46
Filed: 1995-03-30
Abstract: PURPOSE: To make selenium contained in a stack gas harmless by providing a means for supplying a processing agent to insolubilize selenium(IV). CONSTITUTION: Most of the selenium (Se) contained in dust in a stack gas is removed by a dry dust collector 5 and dissolved in a liq. when the dust is brought into contact with the liq. such as water in a repulping means 13 and slurried. At least Se(IV) in the Se dissolved in the slurry is insolubilized by the processing agent of a processing agent supply means 16 and discharged on the solid-phase side in a separating means 15. Meanwhile, the filtrate separated in the means 15 is introduced into the slurry in a desulfurizer 20. Consequently, even Se(VI), which is contained in the stack gas, not insolubilized by the processing agent and dissolved in the filtrate, is allowed to react with the sulfurous acid absorbed in the slurry from the stack gas and reduced to Se(IV).  Accordingly, since the Se dissolved in the circulating liq. consists essentially of Se(IV), the equipment of the entire system is simplified.

Abstract: PURPOSE: To easily obtain a signal amplifier which is strong against a variation of temperature and supply voltage, by executing a compensation against a variation of an ambient temperature by use of a temperature compensating diode, and preventing a variation of output offset by use of a diode having the constant-voltage characteristics.  
     CONSTITUTION: Input voltage e i  which has arrived at an input terminal TA is applied to an inverted input terminal of an operational amplifier 4 through a resistance 1. On the other hand, when a suitable current is made to flow to a diode 7 through a resistance 8 from a positive electric power supply +VS 1 , a temperature compensating signal for negating a negative temperature drift of an output of the amplifier 4 is made by adjusting a variable resistance 9 connected across the diode 7, and this signal is applied to the inverted input terminal of the amplifier 4 through a resistance 2. Subsequently, when a suitable current is made to flow through a diode 12 and a resistance 11 from an earth in order to negate a voltage drop of the diode 7, constant-voltage is obtained across the diode 12. In this way, when a variable resistance 13 connected in parallel is adjusted, the voltage drop of the diode 7 is negated and voltage is applied to the inverted input terminal of the amplifier 4.
