Title: Treatment of gas containing nitrogen trifluoride and its treatment agent
Inventor: ORIHARA ITSUO
IPC: B01D53/68
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To effectively make a gas to be treated harmless by allowing the gas to undergo a chemical reaction with a band- or ribbon-like alloy containing Cr and Fe at a temperature higher than specified to reduce NF3 and then caus ing the residual acid fluoride to chemically react with a neutralizing agent. SOLUTION: When treating NF3 containing an acid fluoride such as HF, SiF4 or WF6 , the mixed gas is allowed to undergo a chemical reaction with a band- or ribbon-like Cr allow, especially an alloy with a Cr content of 16-26% at a temperature not less than 250 deg.C to reduce and detoxify NF3 . Next, the mixed gas is caused to undergo a chemical reaction with a neutralizing agent selected from granular or palletized soda lime, NaOH, KOH, CaO and activated alumina to make the acid fluoride harmless. Thus it is possible to reduce the production of a byproduct gas to almost a zero regarding a sole NF3 gas or NF3 containing an acidic gas such as HF, SiF4 , WF6 or MoF6 K.

Title: Semiconductor memory device
Inventor: HASHIMOTO KIYOKAZU
IPC: G11C17/00
Filed: 1990-10-11
Abstract: PURPOSE:To improve the operating speed and noise margin of a comparison detector even when a reference voltage is in dispersion by providing a constant current load circuit supplying a preset current from a power terminal on an output terminal of a sense amplifier circuit between the power terminal and the output terminal of the sense amplifier circuit. CONSTITUTION:A constant current load circuit 6J supplying a preset current from a power terminal Vcc to an output terminal of a sense amplifier circuit 2J is provided between the power terminal Vcc and the output terminal of the sense amplifier circuit 2J. In this case, a voltage when a memory cell storing a data '1' is selected is extended up to a power supply voltage. Thus, a voltage change when an output voltage of the sense amplifier circuit 2J exceeds a reference voltage is made steep. Thus, the reference voltage is in dispersion, the operating speed and the noise margin of the comparison detector 4J are improved and since a minimum power supply voltage at which the sense amplifier circuit 2J is in operation depends only on a logic threshold level of an inverter, the sense amplifier circuit is operated at a low power supply voltage.
