A jaw clutch coupling mechanism in which spline grooves serving as ball drop-in portions of the clutch are provided with a semi-spherical ball support recess to be engaged with a steel ball by way of linear or surface contact for enhancing the strength of the jaw clutch. A stopper is provided in the shift lever link mechanism to hold the shift lever securely in the forward, neutral or reverse position, and a shock absorber is provided in association with the shifter arm of the jaw clutch to dampen the shocks of engagement of the clutch, ensuring a better feeling in shift lever operations.

A charged beam radiation apparatus includes an auxiliary charged beam emitting mechanism, a main charged beam emitting mechanism, a secondary electron detector, and a computer as a controller. The auxiliary charged beam emitting mechanism emits an auxiliary charged beam of a given acceleration voltage onto a predetermined portion of an electronic device to be measured. The main charged beam emitting mechanism emits a main charged beam of an acceleration voltage lower than that of the auxiliary charged beam onto the predetermined portion and the vicinity of the predetermined portion. The secondary electron detector detects secondary electrons generated from a portion irradiated by the main charged beam. The controller measures a change in a secondary electron signal from the secondary electron detector.

There is disclosed herein a generator control system for use in a power supply system for vehicles in which a battery and an engine-driven generator are connected in parallel with a load. The total load current fed to the load is detected and the generated voltage level is changed by performing field regulation for the generator in accordance with the detected value. Switching of the generated voltage level of the generator is controlled according to the state of the load applied so as to improve power generation efficiency. Certain parameters, such as battery state, engine speed, auto choke and load state, can be provided as an input or inputs to a voltage regulator for the generator.

A wind turbine generator system can regulate the rotational velocity of the wind turbine within an operation range even when the wind velocity suddenly changes and can perform continuous operation of the wind turbine. The wind turbine generator system includes a generator connected to the shaft of the wind turbine and a converter connected to the generator. When the rotational velocity of the wind turbine is within a predetermined range, power outputted from the generator is controlled so as to follow the instruction concerning the generator output given from the wind turbine to the converter. When the rotational velocity of the wind turbine is out of the predetermined range, the power outputted from the generator is controlled without following the instruction concerning generator output given from the wind turbine to the converter.
