摘要： PURPOSE:To provide a stereoscopic light emission display device with excellent durability capable of displaying a stereoscopic light emission pattern, optionally revising the light emission color of the light emission pattern, partially revising the light emission color and manufacturing it at a low cost. CONSTITUTION:Plural kinds and many LEDs 3 with light emission colors different from each other are arranged on respective opposing surfaces of two printed circuit boards 2 arranged oppositely in a prescribed pattern, and a lens part 5 is formed covering the patterns. The lighting and the switching-off of the LEDs are controlled by a drive control circuit, and a light outgoing from the lighted LED 3 is deflected so as to approach to a horizontal direction parallel to the printed circuit board 2 by a deflection film 7 stuck on an inner surface of a transparent cover 6. Thus, the light emission pattern is viewed stereoscopically standing obliquely from the side of outside. By selecting the kinds of the lighting LEDs 3, the light emission color is revised optionally, and is revised partially also.

摘要： PURPOSE:To provide a constitution which has a simple structure, can be manufactured inexpensively, has a long lifetime and does not make a noise, in a rotary emitting display device which displays a rotating stereoscopic emitting pattern. CONSTITUTION:Plural light emitting display sections in which the prescribed numbers of LED are arranged with the prescribed pattern are radially arranged with equal angle interval on a light emitting element substrate 4. Plural light emitting display sections on the substrate 4 are successively selected along the prescribed rotating direction by a driving circuit provided on a driving circuit substrate 11 and a LED is emitted. The emitted light is converged by a lens section 10 formed over the LED and deflected by a deflecting film 3 provided at the inside of a cover 2 so as to close to the horizontal direction in parallel to the substrate 4. Thereby, an emitting pattern caused by emitted light from the external side direction erects and looks stereoscopically, also looked like rotating by a residual image phenomenon of an eye.

摘要： PROBLEM TO BE SOLVED: To very easily attain sure inter-communication at an optional position in a telephone tunnel and to attain communication between the inside and the outside of enclosed blocks by eliminating the need for a large scale installation and for approval of concerned authorities with capability of 2-way communication at an optional position under the work and suppressing a transmission/ reception noise. SOLUTION: A radio wave generated from one transceiver 5 is induced into a sheath 2 of an existing power cable inserted through enclosed blocks by approaching or bringing a radio wave induction coupler of each induction radio transceiver 5 in contact with the sheath 2 of the power cable at two parted positions in the enclosed blocks and the other transceiver 5 receives the induced radio wave to communicate information in mutual information transmission in the enclosed blocks such as a telephone tunnel or a tunnel, and the radio wave induction coupler 7 is provided in each transceiver 5 and the transmission reception signal is controlled by radio wave induction.
