Abstract: <P>PROBLEM TO BE SOLVED: To provide a detector that can detect the position of a moving body even if noise is superimposed on a weak voltage signal from a detection section in the position detection of the moving body.  <P>SOLUTION: A comparator 25 compares a voltage signal from the side of a resistor 21a that is transmitted to a non-inverted input terminal 25a through an electric wire 23a with a voltage signal from the side of a resistor 21b that is transmitted to a non-inverted input terminal 23b through an electric wire 23b for calculation, and outputs a specific voltage level signal according to the result. A variable termination resistor 27 reduces input impedance in the non-inverted input terminal 25a of the comparator 25 by terminating the electric wire 23a. A fixed termination resistor 29 reduces input impedance in the non- inverted input terminal 25b of the comparator 25 by terminating the electric wire 23b. In the variable termination resistor 27 and fixed termination resistor 29, a resistance value is nearly the same as that of resistors 21a and 21b.

IPC: B01D53/72
Filed: 2001-12-25
Abstract: <P>PROBLEM TO BE SOLVED: To efficiently obtain ice in which little amount of solvent is contained.  <P>SOLUTION: Water absorbed the solvent in exhaust gas is frozen in a freezer 21 and the solvent is not frozen from a difference of a coagulation point while water is frozen to become ice and concentrated water. Next, ice is stored in an ice storage tank 56 and this ice storage tank 56 is reduced in pressure by a vacuum pump 92. The freezing point lowers by reducing the pressure in the ice storage tank 56 and melted water containing a large amount of the solvent is efficiently taken out and air bubbles (the solvent is taken in air bubbles) taken in ice can be taken out. Then, the melted water melted in early stages is excluded as concentrated water and separated from ice with high separation efficiency. Ice becomes near to pure water and clean ice not containing the solvent too much is melted to be reutilized as water.  <P>COPYRIGHT: (C)2003,JPO

The fact that no fuel exists near the heater 24 in the fuel chamber 22 is determined based on a fact that fuel pressure in a delivery pipe 31 is lower than a predetermined pressure.  <P>COPYRIGHT: (C)2003,JPO
