IPC: G08G1/095
Filed: 1978-05-29
Abstract: PURPOSE: To prevent the colorless and transparent lens from shining as if it irradiated the colored beams via the sunlight and the like at the non-glowing time by distributing the color light source to radiate the colored beams at the back of the lens body.  
     CONSTITUTION: Lens substance 3 attached in front of device main body 1 is colorless and transparent. And color light source 4 distributed at the back body 3 is formed by coating phosphor 9 which emits the colored beams at the glowing time via exciatation of the ultraviolet rays and turns opque at the non-glowing time respectively. Thus, even if the external beams such as the sunlight ot the like enters main body 1 through lens 3, it is reflected by reflector 14 and thus not colored. Furthermore, the greater part of the sumlight coming in through phosphor 9 is cut off, and thus the reflected light is weak. Accordingly, the fact that the colored beams are radiated by the external light at the non-glowing time or lens 3 shines bright can be prevented.

Title: Semiconductor device
IPC: H01L27/06
Filed: 1992-03-19
Abstract: PURPOSE:To improve the P/V ratio of a semiconductor device so that the device can have an enlarged logical margin by using a resonance tunneling hot electron transistor (RHET) as a load resistance element. CONSTITUTION:A serial circuit of an RHET 3 and HEMT 2 is constituted by using the RHET 3 as a load resistance element. In other words, the RHET 3 and HEMT 2 (an HBT can also be used in place of the HEMT) are connected in series between a power source Vcc and earth GND as a load element and active element, respectively. The base of the RHET 3 is connected to its collector at the same potential (Vcc). Since a collector barrier exists as compared with a resonance tunnel barrier composed only of a double barrier, electrons passed through the double barrier can be reflected by means of the collector barrier. Therefore, the valley current of this semiconductor device can be reduced and, as a result, the P/V ratio of the device can be improved. The improvement in P/V ratio can enlarge the logical margin of circuit operations.
