Improved approaches to providing thermal and power management for a computing device are disclosed. These approaches facilitate intelligent control of a processor's clock frequency and / or a fan's speed so as to provide thermal and / or power management for the computing device.

Onto the surface of a dressing tool for removing the clogging of an abrasive cloth, diamond grains of plural groups each having a different average particle diameter are subjected to be mixed and then fixed. In this state, the upper end of small diamond grains 4 is projected over nickel plating 2. Thereby foreign substances aggregated in the concave of the abrasive cloth are effectively removed and at the same time wearing the surface of the nickel plating 2 is prevented. Achieved are the stabilization of a polishing speed in polishing and the inhibition of dropping out diamond grains and wearing nickel plating in dressing.

A turbocharger in which a drive shaft supports at one end a turbine driven by exhaust gases from an internal combustion engine. The end of the drive shaft remote from the turbine supports a drive connection which is coupled to an output shaft of the driving engine. The shaft is supported in a housing by a first bearing adjacent the turbine and a second bearing adjacent the drive coupling. The first and second bearings each define an inner bearing surface relative to which the shaft rotates and an outer bearing surface which rotates relative to the housing. The first and second bearings are mechanically coupled together such that they rotate relative to the housing at the same speed. Coupling the two bearings together ensures that directional forces applied to the bearing at the end adjacent the drive connection which might cause that bearing to seize are resisted by torque delivered from the bearing at the other end of the shaft.

A boat or ship (marine vessel) can be powered and propelled by using wind or solar energy. This propulsion results in the forward movement and six degrees of motion (roll, heave, pitch, yaw, surge, and sway) of the marine vessel. These motions have kinetic energy. This invention capitalizes on the fact that the solar wind and wave energy are cyclical by nature. The present invention enables the vessel to store energy harvested from these energy sources during periods when levels of energy is available from wind, solar, or the motion of the vessel in waves. This invention makes this stored energy available for use during periods when the external natural sources of energy (wind, wave, or solar) are not available in adequate quantities to maintain a reasonable speed of advance for the marine vessel. The harvesting of the energy during high energy cycles, storing it and using it when needed in this invention allows a marine vessel to get maximum speed of advance over a course. In this invention the marine vessel can maintain faster average speed without reliance on any fossil or chemical fuel and by only using renewable energy sources. In this invention the vessel is normally driven by wind channeling methods like canvas or foil sails or Flettner rotors. In addition to this, the vessel can be propelled by propulsion thrusters such as propellers, rim driven thrusters, azimuthing drives, water jets or other means of thrusting and propelling the vessel. These propulsion devices are driven by regenerative electric motors using stored electric energy in batteries on the vessel. The energy stored in the battery bank is used to provide supplemental or primary propulsion during cyclical periods when natural sources of wind, wave or solar energy are low. These same thrusters and their electric motors work in reverse to generate and harvest energy when wind levels are high and as the marine vessel is moving forward at higher speeds while being propelled by wind energy. In this invention the batteries, which are dense and heavy, to store this energy, are secured in the bottom of the marine vessel also serve as ballast to keep the vessel upright. This serves to lower the marine vessel's center of gravity to get the maximum hull stability for safety. This also helps the vessel channel maximum available wind energy to propel the vessel and harvest energy whenever stronger winds permit.

A servo control device 10 connected to servo motors 21 to control them includes a digital logic circuit 11 having a predetermined bit width. The digital logic circuit 11 includes at least one pair of parallel arithmetical circuits 11a, 11b.

A control method according for an impact wrench includes ascertaining whether the impact wrench applies an impact when the drive shaft rotates in a lower speed range. The speed of the drive shaft then is increased to a higher speed range as a function of an ascertained impact during the rotation in the lower speed range.

A windmill design in which all rigid blades are replaced by sail-type Blades that are only supported by tension. Each Blade is connected to a central Hub and outer Rim by means of two Spokes, and is twisted in shape to maintain a materially constant free wheeling angular velocity at any radial location along the Blade while preserving a near-constant width. The cross section of the Rim is wing-shaped to produce laminar flow of air over the Blades.
