Title: Illuminator
Inventor: YO JUNSHO
IPC: F21V1/02
Filed: 1999-10-27
Abstract: PROBLEM TO BE SOLVED: To provide an illuminator, which transmits light tendered in a chassis. SOLUTION: A chassis 1 and a shade 2 are different from each other in light transmissivity. An illuminator is opaque when not emitting light.

Filed: 1988-12-02
Abstract: PURPOSE:To increase the rate of the area of the Schottky junction area of a first device layer by making a desirable Schottky barrier height obtainable to the first semiconductor layer in a Schottky barrier diode (JBS) and a third semiconductor layer to make a function which pinches off a power supplying path when a reverse bias voltage is applied. CONSTITUTION:It is arranged that depletion layers 18 produced in a third semiconductor layer 19 when a low reverse bias voltage VR including zero is applied across first and second metallic films 16 and 17 can be coupled with each other. Namely, adjustment of impurity concentration to a low level is mainly performed on the third semiconductor layer 19 in a JBS so that the power supplying path can be pinched off. On the contrary, the impurity concentration of the first semiconductor layer 12A is made higher than that of the layer 19 so that a low forward voltage value can be obtained. Therefore, it is not necessary to preferentially consider the pinching-off of the power supplying path with respect to the interval between each opposite-conduction type semiconductor layers 14. Therefore, the rate of the area which makes Schottky contact of the first semiconductor layer 12A can be increased.

Filed: 1986-12-24
Abstract: PURPOSE:To attain a stable radio communication while S/N is kept constant even if noise level is changed by controlling a high frequency output of a radio transmitter in response to a noise detection level. CONSTITUTION:A noise detector 10 is added to the transmission circuit of a radio transmitter, a noise caught by a transmission antenna 4 is rectified and extracted as a DC signal, the DC signal controls a current supplied to the transmission circuit to adjust the high frequency output automatically. That is, when the noise level is increased, the noise signal is rectified and the DC signal level rises and the supply current to the transmission circuit controlled by the DC signal is increased and the high frequency output is increased attended therewith. Conversely, when the noise level is decreased, the DC signal is decreased, the supply current is decreased and the high frequency output is lowered. Thus, the high frequency output is increased/decreased in response to the change in the external noise level to ensure a prescribed S/N and stable communication is attained by using a radio equipment with a minute output.
