An internal combustion engine including an intake passage fuel injection valve for injecting fuel into an intake passage and a cylinder inside fuel injection valve for injecting fuel into a combustion chamber, includes: a fuel pump pressurizing and feeding fuel, which is fed from a fuel tank, to the cylinder inside fuel injection valve; a securing part provided on a cylinder head member of the internal combustion engine to secure the fuel pump; an introducing member having heat conductivity, the introducing member connected to the fuel pump and formed with: a first introducing path for introducing fuel from the fuel tank to the fuel pump; and a second introducing path for introducing fuel from the fuel tank to the intake passage fuel injection valve; and a heat transmitting member transmitting heat between the introducing member and the securing part.

Internal combustion engine

By connecting a grounding conductor pattern directly to a grounding terminal of a field-effect transistor and connecting a series circuit comprising a stabilized resistor and an open-circuit stub having a length equal to quarter of a parallel resonance frequency, undesirable parallel resonance caused by the grounding conductor pattern and the open-circuit stub is suppressed, and a voltage drop in the stabilized resistor is suppressed when a bias voltage is applied to the field-effect transistor. Accordingly, the operation of a microwave amplifier is stabilized.

Microwave amplifier optimized for stable operation

A thyris a thyristor is provided in which a lifetime of a minority carrier is controlled to improve the trade-off relationship between an ON-state voltage and a turn-off time and attain a high frequency and a low loss. Shielding members formed of metal plates are provided respectively in spaces above a plane on which a cathode electrode is provided and a plane on which an anode electrode is provided.
