Title: Differential amplifier circuit
Inventor: SHIROKURA MINORU
IPC: H03F3/45
Filed: 2002-06-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a differential amplifier circuit for preparing an amplifier whose through-rate is large, and whose DC characteristics are satisfactory.  <P>SOLUTION: When the collectors of transistors Q3 and Q4 are respectively connected through capacitors C1 and C2 to the emitters of transistors Q1 and Q2, negative feedback is generated by the capacitors in a high frequency area. Therefore, when the set of the transistors Q1 and Q3 and the set of the transistors Q2 and Q4 are respectively considered as one equivalent transistor, the mutual conductances of the equivalent transistors are made smaller than DC in the high frequency area. As a result, the capacitance value of the capacitor C3 for frequency compensation can be reduced, and a through-rate can be increased, and the mutual conductances in the DC can be increased, and DC characteristics can be made satisfactory.  <P>COPYRIGHT: (C)2004,JPO

Title: Fuel vapor treatment apparatus
Inventor: KONO AKIHIRO
IPC: F02M25/08
Filed: 2002-07-15
Abstract: <P>PROBLEM TO BE SOLVED: To prevent generation of excessive negative pressure due to clogging of a canister without complicating the structure of a fuel vapor treatment apparatus.  <P>SOLUTION: When a pressure drop amount PCNASN in a system is not larger than a criterion CANING#, an opening EVPS of a purge valve is decreased. By decreasing the EVPS, the intake negative pressure of an engine which tries to work to the canister side is decreased, therefore a disadvantage of deformation due to the application of high negative pressure to a fuel tank can be avoided. The action of the negative pressure is decreased by purge valve opening decrease control, thus no valve is required between the canister and the fuel tank, and disadvantage does not occur in a leak diagnosis. There is no increase in the number of parts or cost.  <P>COPYRIGHT: (C)2004,JPO
