Abstract: PURPOSE: To attain high quantization efficiency and superior output with a small dark current by forming adjacent regions, consisting of p-conductive type and n-conductive type silicon carbide components, and forming p-n junction between the adjacent regions. CONSTITUTION: A diode 10 is formed by a single-crystal substrate 11, consisting of 1st conductive silicon carbide, a 1st epitaxial layer 12 consisting of silicon carbide having the same conductive type as the substrate 11 and formed on the substrate 11, and a top epitaxial layer 13 consisting of silicon carbide formed on the layer 12 and allowed to be exposed to an incident electromagnetic radiation. A top layer 13 has a conductive type which is reverse to that of the 1st layer 12 and the substrate 11. Between the 1st epitaxial layer 12 and the top epitaxial layer 13, a p-n junction 14 is formed. Ohmic contacts 15, 16 are respectively formed on the top layer 13 and the substrate 11. The density of the layers 12, 13 is mutually different. Consequently the dark current of a diode can be reduced, and the sensitivity of a photodiode can be increased.

Abstract: PURPOSE:To perform optical switch control based upon light by providing a means which separates the optical path of output light of a laser device capable of oscillating in plural modes according to plural modes and a mode selecting means for making light incident on the laser device and selects one of the modes. CONSTITUTION:Input light is incident on a polarizer 2, passed through reflecting mirrors 3 and 4, quarter-wavelength plates 5 and 6, and an active layer 7, and outputted to an optical path 10 or 11 through a quarter-wavelength plate 8 and a polarization separating element 9. The laser device oscillates in a hybrid mode and once it oscillates in either mode, feedback is provided in a resonator, performing stable oscillation. At this time, output light of TE mode is projected on, for example, the optical path 10, but no light is projected on the optical path 11. Here, when light of TM mode is made incident from the optical path 11 and the incident light exceeds some threshold value, the laser device oscillates in the other mode and switching from the optical path 10 to the optical path 11 is carried out. Further, the optical path 11 is switched to the optical path 10 by making light of TE mode incident on the optical path 10. Thus, switch control based upon light is performed.

Title: Automatic focus adjusting device of variable focus type camera
Inventor: WAKABAYASHI HIROSHI
IPC: H04N9/64
Filed: 1984-03-23
Abstract: PURPOSE:To simplify a moving mechanism which moves an optical system in the optical axis direction by providing an intermittent interlocking mechanism between the main optical system and a distance detecting means, and interrupting their interlocking operation in an intermediate section on the track of the main optical system. CONSTITUTION:An interlocking lever 202 for telephoto distance and an interlocking lever 203 for wide-angle distance are fitted to the guide shaft 19 of the base plate 10 of the main optical system 3, and tips are engaged with a distance measurement lever 209. An interlocking pin 201 moved by the shaft 19 is provided between the levers 202 and 203. Therefore, the pin 201 engages the lever 202 during the extension of the main optical system 3 and engages the lever 203 during the contraction while the engagement is interrupted at the intermediate position. For example, when the optical system is extended from the wide-angle side to the telephoto side, the pin 201 leaves the lever 203 and moves toward the lever 202, but the interlocking is interrupted in the intermediate section and a focus adjustment is made without the movement of a photodetecting element 213; and a subordinate optical system is interposed between them. Consequently, the moving mechanism for the optical system is simplified.

Title: Reactor container vessel
Inventor: FUKUI TORU
IPC: G21C9/004
Filed: 1991-03-20
Abstract: PURPOSE:To increase a pressure suppression effect by increasing the temperature difference between a pressure suppression chamber and its outer circumference so as to radiate a large amount of heat to the outer circumference, or by increas ing heat radiation from a reactor container vessel. CONSTITUTION:At the time of an accident, the noncondensible gas inside the drywell 3 of a reactor pressure vessel 2 is accompaniedly pushed out by the steam being discharged from the vessel 2 and flows into a pressure control pool 5 through vent pipes 7, and is accumulated in a first space 61, and then flows into a second space 62. Then, the steam flows into the pool 5 through pipes 7, so that the water temperature is raised, and also the total pressure is increased. Since the space 62 is cooled, the steam flowing in together with the noncondensible gas is condensed, and as a result, the pressure in the space 62 becomes lower than that in the space 61, and again the steam flows in from the space 61 into the space 62. This action is repeated, and all the noncondensible gases in the wetwell 6 are accumulated in the space 62. Since the return of gaseous phase to the space 61 is restricted, the space 61 is filled only with steam.
