摘要:
In this junction element 1, when a forward voltage is applied, a depletion layer is formed in a semiconductor layer 2, prohibiting electrons present in an electrode layer 4 to move into the semiconductor layer 2. For this reason, a majority of holes in a semiconductor layer 3 do not disappear by recombination with conduction electrons in the semiconductor layer 2, but reach the electrode layer 4 while diffusing into the semiconductor layer 2. Accordingly, the junction element 1 can serve as a good conductor for holes, while avoiding the influence of a resistance value, and allows a current to flow therethrough at a level equal to or more than that achieved by a semiconductor element formed of a Si or SiC semiconductor. The present invention is applicable to any semiconductor material in which at least one of a donor level and an acceptor level is located at a sufficiently deep position beyond a thermal excitation energy at an operating temperature, such as diamond, zinc oxide (ZnO), aluminum nitride (AlN), or boron nitride (BN). The present invention is also applicable to even a material having a shallow impurity level at room temperature, such as silicon (Si), silicon carbide (SiC), gallium nitride (GaN), gallium arsenide (GaAs), or germanium (Ge), as long as operation is performed at such a low temperature that the thermal excitation energy can be sufficiently small.
摘要:
A head cap for an aerosol type atomizer is proposed in which a residual gas that remains in the container after the use of the aerosol type atomizer is ended are discharged easily and safely, and which is so structured that the aerosol type atomizer cannot be falsely operated while it is being used. It comprises a cap body mounted over a top of a container accommodating its contents, and a movable member for spray operation disposed inside of the cap body and having a fluid channel extending from a stem fitting part for fitting with a stem and leading to a spray port, the movable member for spray operation having a push button such that pushing down the push button to take a spray position sprays contents of the container from the spray port via the fluid channel, wherein the cap body has a side face elastically deformable so that when the push button of the movable member for spray operation is pushed down to take the spray position, pressing the side face of the cap body inwards locks the movable member for spray operation with the side face to hold the movable member for spray operation at the spray position.
