A fixing structure of an indoor lamp includes a lamp unit and an interior wall member. The lamp unit includes a design part arranged at an indoor side of the interior wall member and a functional part arranged at an outdoor side of the interior wall member and assembled with the design part through a lamp attachment hole in a state that the functional part holds the interior wall member therebetween. The functional part has a connector portion for connecting a connector. The design part has a regulating portion which forms a connector insertion portion together with the connector portion when the design part is assembled with the functional part. The regulating portion engages with the connector inserted into the connector insertion portion to regulate displacement of the design part in a disengagement direction from the functional part.

In a cylinder head structure of an engine, a structure of an oil passage is simplified to downside the engine and to provide proper flow of cooling water in the cylinder head. A partition wall is disposed in the cylinder head to separate an upward valve operating chamber from a downward water jacket. A boss section is formed at a position lower than the partition wall in an edge wall of the cylinder head, and has one end joined to a chain case and the other end protruding into the water jacket. A branch oil passage is formed in the boss section. The branch oil passage has a valve upstream-side passage section specified by a section toward the chain case with respect to a junction with a cylinder head-side oil passage. The linear communication passage section communicates between an end portion of the branch oil passage protruding into the water jacket and a camshaft cap coupling surface of a second camshaft bearing section.

摘要:
In a radio communication system, an electronic component for high frequency power amplifier carries out the detection of output level, required for feedback control of the output power of a high frequency power amplification circuit, by current detection. The electronic component has an error amplifier. The error amplifier compares an output level detection signal with an output level instruction signal, and generates a signal for controlling the gain of the high frequency power amplification circuit according to the difference between them. For the error amplifier, a low-pass amplification circuit is used. The amplification circuit is provided with, between its output terminal and its inverting input terminal, a phase compensation circuit. The phase compensation circuit comprises a resistance element, and another resistance element and a capacitive element in series connected in parallel with the resistance element.
