摘要:
A voltage control circuit is connected to a voltage source. The voltage control circuit changes voltages of n different values and outputs them to an output node of the voltage control circuit according to control signals. A first switch element is connected between the output node of the voltage control circuit and a reference voltage node, and a second switch element is connected between the output node of the voltage control circuit and an output node of the voltage source. The first switch element is controlled so as to be conductive when the voltage control circuit changes the voltage of the output node from a first voltage to a second voltage that is lower than the first voltage, and the second switch element is controlled so as to be conductive when the voltage control circuit changes the voltage of the output node from a second voltage to a first voltage.

The center of rotation of a disk medium 1 when servo information is written thereto coincides as accurately as possible with its center of rotation in the drive into which the disk medium 1 is assembled.The magnetic disk medium 1 is fixed to a spindle hub 4. A centering pin 8a of a push-aside mechanism 9 pushes aside the magnetic disk medium 1 with respect to the center of the spindle hub 4 until the disk-to-hub gap is moved to one side. Then, with a centering pin 8b of a come-back mechanism 10 placed in the same line intersecting with the center of the spindle, the magnetic disk medium 1 is pushed back to the opposite side.

A cavity back golf club head having a bridge member and a damping element is disclosed. The bridge member extends across a first rear cavity connecting a heel and a toe of the golf club head to control the trajectory of a golf ball. For the longer iron clubs, a damping element extends from the sole portion of the cavity back golf club head to the bridge member to define a second cavity to further influence the trajectory of the golf ball. For the shorter iron clubs, the damping element extends from the top portion of the cavity back golf club head to the bridge member. The damping element may reduce the vibration and sound of the golf club head upon impact with a golf ball.

The method for fabricating a semiconductor integrated circuit device disclosed includes the steps wherein an active region is defined so as to be surrounded by an insulating film on a silicon substrate, a surface of the active region and a semiconductor layer that extends underneath the insulating film are changed to an amorphous state by implantation of ions from oblique angles, a metal film is formed over the silicon substrate, and a metal silicide layer is formed by a thermal-treatment causing the metal film and silicon in the amorphous state to react with each other. In this way, it is possible to form a sufficiently thick silicide layer even on a narrow line width diffusion layer.

A method for manufacturing an integrated circuit, wherein, before providing an IC composite by forming a metal film on an IC assembly which includes a semiconductor substrate and a silicon part formed along the substrate and consisting essentially of silicon, an amorphous region is formed into the silicon part. The IC composite is subjected to first primary and secondary heat treatments in a nitrogen atmosphere and then to a second heat treatment at 600.degree.-700.degree. C., 700.degree.-900.degree. C., and 700.degree.-900.degree. C. to turn the metal film on the silicon part into a metal silicide film of excellent uniformity. The assembly has a silicon dioxide portion, on which the metal film is turned during the first primary and secondary heat treatments into a metal nitride film. The second heat treatment is carried out after the removal of the metal nitride film.

In a brake system of a vehicle adapted to be operated automatically, the brake system includes a forecasting mechanism for forecasting a need of automatic braking, and a pump to provide a source of a pressurized working fluid for the automatic braking is started when a need of an automatic braking is forecast. By such a need forecast starting of the pump, the brake system can automatically apply an effective braking to a vehicle wheel or wheels, with no accumulator for storing the pressurized working fluid. The pump need forecasting may depend upon an estimation of a turn behavior of the vehicle and/or a detection of an obstacle in front of the vehicle.
