摘要:
An illumination device with a toning function in which possibility of moisture and dust intruding into the case is reduced with a simple mechanism is realized. The illumination device includes a light emitting element light source (17) mounted on a substrate inside the case unit (21), an external gear-shaped fluorescent-substance plate (41) having a configuration in which a light emitting color of an applied fluorescent substance differs according to position and being arranged above the light emitting element light source (17) inside the case unit (21), and an internal gear-shaped adjustment ring (43) arranged so as to mesh with the external teeth of the fluorescent-substance plate (41), wherein the adjustment ring (43) is arranged to be positioned on the outer periphery of the main body under a lens dome (11), and when the adjustment ring (43) is rotated, a relative positional relationship between a color distribution applied on the fluorescent-substance plate (41) and the light emitting element light source (17) is changed.

A waveguide to microstrip converter allowing size reduction as well as providing good cross polar discrimination and input VSWR characteristic. The waveguide to microstrip converter includes a structure of an orthogonal transducer formed of a circular waveguide and a rectangular waveguide integrally formed with and orthogonal to the circular waveguide. A first probe and a second probe are respectively coupled to the circular waveguide and rectangular waveguide. An output terminal of the first probe and an output terminal of the second probe are formed on the same plane and connected to respective microstrip lines.

In a converter for satellite broadcast reception having a fixing structure provided with a circuit board, a plurality of radio-frequency circuits mounted on the circuit board and separated from one another by a grounding pattern, a chassis having ribs arranged in a pattern that corresponds to the grounding pattern, and a mount plate placed on the back surface of the circuit board, a rubber plate having resilience is placed between the circuit board and the mount plate. This permits the grounding pressure with which the grounding pattern of the circuit board is kept in contact with the chassis to be distributed uniformly, and thereby permits stable grounding to be achieved.

An objective lens actuator includes an objective-lens-side main magnet and two stationary-holder-side main magnets mounted to a base body. The objective-lens-side main magnet is positioned to face the two stationary-holder-side main magnets across a gap. The magnets form a magnetic circuit producing magnetic flux extending from either the objective-lens-side main magnet or the two stationary-holder-side main magnets to the remaining magnet(s). The objective lens holder includes a focusing coil and a tilting coil. The focusing coil is located so that the objective-lens-side main magnet and the two stationary-holder-side main magnets are present outside and inside a winding of the focusing coil respectively. The tilting coil is located so that: the objective-lens-side main magnet is present outside a winding of the tilting coil; one of the stationary-holder-side main magnets is present inside the winding; and the remaining one of the stationary-holder-side main magnets is present outside the winding. The structure enables tilt correction and restrains undesirable tilting of the objective lens in a focusing action, for example.

A chuck portion provided to keep a fixed positional relation with respect to a housing, holds a light source unit detachably. This chuck portion is displaced from an advanced position to a retracted position to displace the light source unit which is in a provisional position with respect to the housing, in a direction being away from the housing along a reference axis and the light source unit is retracted from the housing. In a state where the light source unit which is in this position is held by the chuck portion, the light source unit is slid and displaced in a direction crossing the reference axis with respect to the housing, angularly displaced about the reference axis and an axis crossing the reference axis, and then fixed to the housing.
