A system and method for preventing crosstalk noise from being superimposed on a read signal due to noise from a heater line for a slider in a recording disk drive is disclosed. A heater line pair to the slider is not grounded but is in a floating state with respect to an actuator support structure. A heater driver allows a heater current to flow between a positive power supply voltage and a negative power supply voltage. The heater line pair is not grounded, so an impedance is high as viewed from a magnetic disk. Thus, it is possible to effectively suppress a noise transmitted from the magnetic disk and read signal quality is kept from deteriorating due to the crosstalk from the heater line.

An ion wind generator is provided at the back of a light source. The ion wind generator negatively ionizes air by corona discharges using negative-side needle electrodes and draws the negatively-ionized air to a ground-side mesh electrode to allow an airflow to be occurred. A photocatalyst filter is provided at the back of the ion wind generator. Even if ozone (O3) is generated and a lower fatty acid is composed by the ozone and alcohol remained in a casing, the lower fatty acid is decomposed into alcohol and oxygen by the photocatalyst filter.

An illumination apparatus includes: a group of light source segments; a group of condenser lenses arrayed as opposed to the group of light source segments, and a group of rectangular lens elements arrayed as opposed to the group of condenser lenses for converging a light ray transmitted through the opposing condenser lens; and an illumination optical system for guiding the rays to an illumination plane. The lens elements have a shape of a rectangle and are arrayed in a rectangular effective area in such a way that a longitudinal axis of each lens elements intersects an axis passing a side of the effective area at 45°.

The projection type video display includes three illuminating devices (51R-1, 51G, and 51B). Each illuminating device includes a taper type rod integrator and a cuboid shaped rod integrator. The illuminating device (51R-1) emits red light; the illuminating device (51G) emits green light; and the illuminating device (51B) emits blue light. The illuminating device (51R-1) has a Fresnel lens. The illuminating devices (51G and 51B) do not have a Fresnel lens.
摘要:
A mechanical brake actuator realizing the miniaturization of the entire device and the reduction of the parts costs is provided. When the brake lever rotates in the cable releasing direction, the connecting pin can be connected with the free end of the brake lever from one facing plate side while the other facing plate restricts the movement of the connecting pin, and the clip (30) is set on one facing plate (23b) so as to restrict the movement of the connecting pin after connecting the brake cable and the brake lever via the connecting pin.
