An adjustment system for a video monitor including a microprocessor, a D/A converter, an on-screen display controller circuit and an operator input unit. The microprocessor is configured to output adjustment signals to input circuits of the video monitor via the D/A converter and overlay a message concerning image adjustment on a display screen via the on-screen display controller circuit. The adjustment system corrects the problem of conventional adjustment systems wherein adjustment operation cannot be carried out unless an operator is fully aware of and skilled in the adjustment procedure.

To prevent disconnection of wind turbine generators due to changes in wind conditions even if the wind turbine generators is operated to limit the power output. A plurality of wind turbine generators that generate electric power by the rotation of rotors are provided in a wind farm are interconnected and are operated while the power outputs are limited in advance so as to be able to further supply electric power to a utility grid in response to a decrease in the frequency or voltage of the utility grid. The rotational speed of the rotor, which is a physical quantity related to increase and decrease in the power output of the wind turbine generator, is measured for each of the wind turbine generators by a wind-turbine control system, and the limitation amount of the power output of the wind turbine generator is set for each of the wind turbine generators by a central control system on the basis of the rotational speed of the rotor measured.

Yaw control is performed such that a nacelle faces into an actual main wind direction. The actual wind direction is estimated by detecting the main wind direction with an anemoscope (wind direction detecting means), assuming the actual wind direction by assuming a wind direction offset value, which is a deviation between the main wind direction and the actual wind direction, which is a direction of wind which blows in actual use, at a predetermined wind speed with a wind direction assuming unit (wind direction assuming means), calculating an average generator output power for a predetermined period of time in the assumed actual wind direction with an average-generator-output-power calculation unit (average-generator-output-power calculation means), approximating the average generator output power with respect to the assumed wind direction offset value to a quadratic curve with an actual wind direction estimation unit (actual wind direction estimation means), and estimating the wind direction offset value at the time when the average generator output power is the maximum in the approximated quadratic curve to be an actual offset value.

A speaker system removably attachable to a video monitor is described which would eliminate the complexity in mounting the speaker system as an add-on unit as well as the ungraceful appearance of the video monitor when the speaker system is removed. The top side of a case incorporating speakers is formed to match the shape of the bottom of the front panel of the video monitor. The speaker system can be mounted on the bottom of the front panel of the video monitor, which is supported on top of a base, as a locking member formed on the top of the case is engaged with a locking hole formed in the bottom of the front panel, or a locking member formed on the bottom of the front panel is engaged with a locking hole formed in the top of the case. Due to lightweight and compact construction, the speaker system can be integrally mounted on the video monitor by using dead space formed between the video monitor and its base and it can be easily removed therefrom.

A MOS transistor semiconductor device has a gate electrode portion with a spacer film, diffused regions diffused with dopants, and element-separating regions. After the formation of the gate on the substrate, a spacer oxide is formed adjacent to the gate. A polysilicon layer doped with the same dopants as the diffused regions is formed between the element-separating regions and the spacer film. The polysilicon layer is overlaps portions of the gate electrode and the element-separating regions that are close to the diffused regions. Thermal diffusion of the dopants from the polysilicon layer to the substrate is performed to further dope the diffused regions. After an insulation layer is formed over the polysilicon layer, connection holes are formed through the insulation layer to connect the polysilicon layer to metal interconnects. In this MOS transistor, the polysilicon layer provides holes that are larger in diameter than holes at the openings of the diffused regions that are part of the substrate surface. Therefore, the area on the silicon substrate surface occupied by diffused layers is reduced to permit semiconductor elements to be packed at a high density. The resistances of interconnects are also suppressed.

A parking gear mounting structure for an automatic transmission includes an input shaft which is supported by a transmission case in such a manner as to be prevented from moving radially with respect to an axis of the input shaft, an output shaft which is arranged coaxially with the input shaft and is also supported by the transmission case in such a manner as to be prevented from moving radially with respect to an axis of the output shaft, and a planetary gearset provided between the input shaft and the output shaft. The planetary gearset has a pinion carrier which is provided with a parking gear in a fixed relationship thereto. The parking gear is engageable with a parking gear locking member for locking the parking gear when the transmission is in parking. The pinion carrier is mounted onto the output shaft to rotate as a unit with the output shaft. A connecting member is provided for transmitting driving power from the input shaft to the planetary gearset. The connecting member is in a fixed relationship to the input shaft. A bearing is arranged between the pinion carrier and the connecting member such that the pinion carrier is radially supported by the connecting member through the bearing to prevent a radial displacement of the pinion carrier with respect to the axis of the output shaft.
