摘要:
In an electronic circuit comprising a modulator (35) and used in each substation of a TDMA system and responsive to a baseband data signal sequence for producing a burst in accordance with a first burst control pulse, spurious components resulting in the burst from the first burst control pulse are eliminated either by allowing the data sequence to pass through a low-pass filter (36) after switching (45) the sequence by the first burst control pulse or by filtering the first burst control pulse by a low-pass filter before switching a local oscillation signal by the first control pulse. An additional switching circuit may switch either a modulated signal supplied from the modulator or the local oscillation signal in response to a second burst control pulse that disappears after extinction of the first burst control pulse. Alternatively, a modifying circuit reverses polarities of a preceding and a following data signals immediately preceding and following the sequence, relative to a leading and a trailing end data signals of the sequence.

An image display device element, a filter element, and a reflective element allow a brightened display screen displaying red, green, blue, and composite colors through use of a single light-emitting portion. The image display device has a first element where a boundary wavelength between light absorption and light transmission or between reflection in an oblique direction and light transmission is variable or fixed and a second element where a wavelength region to be reflected is variable or fixed. The boundary wavelength of the first element and/or the wavelength region of the second element is variable. A positional relationship exists where light transmitted by the first element is incident on the second element. Controlling overlap between light transmission bands of the elements through varying the boundary wavelength of the first element and/or the wavelength region of the second element varies a band and amount of light reflected by the second element.

In a navigation apparatus having a cradle unit that is fastenable to a vehicle and is equipped with at least a microcomputer; and a front panel unit that is attachable to and detachable from the cradle unit and is equipped with at least a display displaying map data and a microcomputer performing a navigation function to indicate a determined location of the vehicle on the map data, it is configured such that a panel is integrally formed at bottom of the cradle unit to be attachable to the vehicle. With this, it becomes possible to provide the navigation apparatus configured such that a member having a microcomputer performing a navigation function is attachable/detachable to/from the main body, i.e., the base unit, thereby improving ease of use, that the member can be easily attached to the dashboard of the vehicle, and that unnatural impression is prevented from arising in the appearance.

An optical disc driving device has a metallic exterior casing composed of a first casing and a second casing and an internal unit to be housed in the exterior casing. The internal unit includes an optical pickup unit having an optical pickup part that moves in radial directions of an optical disc to perform recording or reproduction of information signals on the optical disc. At a portion where the optical pickup part moved radially outward of the optical disc makes a closest approach to, in either one of the first casing or the second casing opposed to the first casting, a protrusion for electrically connecting the first casing and the second casing to each other is provided.
