Abstract: PURPOSE:To reduce the leakage current to such extent that it becomes negligible by forming the laminar structure on a semiconductor substrate, which is composed of a semi-insulating first semiconductor layer, a second semiconductor layer of the first conductive type whose forbidden band gap is narrower than that of the first semiconductor layer, a third semiconductor layer of the first conductive type whose forbidden band gap is wider than that of the second semiconductor layer and providing the fourth semiconductor layer of the second conductive type which is formed in contact with the semiconductor substrate and the side edges of the first, second and third semiconductor layers. CONSTITUTION:On a GaAs substrate 13, an undoped AlxGa1-xAs layer 17, undoped GaAs layer 3 which is to be an active layer, and Se doped N-type AlxGa1-xAs layer 4 are grown in order by epitaxy using an organic metal gas-phase growth technique. On the grown layers, an SiO2 or SiN film is deposited and a predetermined region is removed by etching into stripe form to expose the surface of the grown layer. After removing the grown layer by etching, the selective growth, for example, by liquid-phase epitaxy is made to form a P-type AlGaAs layer 18 including Zn. A P-type electrode 10 and an N-type electrode 12 are arranged on the P-type AlGaAs layer and the N-type AlGaAs layer, respectively.

IPC: G03G15/16
Filed: 1986-09-29
Abstract: PURPOSE:To contrive the stable separation of a copying form by electrostatically transferring toner particles on the copying form inserted between a stepless belt means partially having a semiconductor material with a specific electric resistance, a photosensitive body and a belt. CONSTITUTION:A conveyance belt 26 is provided with a grounding roller 30 made of a semiconductor material with an electric resistance of 10<10>-10<13>OMEGA-cm. Negatively electrified toner particles on a photosensitive drum 10 are attracted by a + true charge on the conveyance belt 26 or a polarization charge on the copying form 7 in the direction of the conveyance belt 26 in the vicinity of an abutting part against the photosensitive body and the conveyance belt. The toner particles are transferred to the copying from attracted on the conveyance belt 26. If selenium is used for the photosensitive body 10, the surface potential of the conveyance belt 26 required 2KV or above in order to transfer the toner particles against the surface potential. The conveyance belt provides the high potential of 2.5-3KV, thereby transferring satisfactorily. Thus the sheet can be isolated stably.

Abstract: PURPOSE:To make effective recovery of thermal energy and prevent harmful gas from mixing into exhaust gas by shunting and exhausting part of combustion gas from a middle position of a rotating furnace through a thermal conductive wall, and bringing the remaining part into contact with solid matter and returning it from the upper end side to the lower end side. CONSTITUTION:Solid matter (stock material) is fed to a rotating furnace 1 from an introduction tube 8 via an inlet 2, and in a preheating zone it is heated via a thermally conductive wall 5 by part of combustion gas flowing through a shunt passageaway 6 and is directly heated by the remaining flowing in the preheating zone II. Hereby, the solid matter is raised in its temperature and flows toward the lower end of the rotating furnace. Organic matter involved in the solid matter is heated and decomposed to produce varieties of inorganic and organic gases. These gases are entrained in the combustion gas flowing in the preheating zone II and fed from the inlet 2 into the introduction tube 8, and further reaches an inlet 12 from a blower via a return tube 15. The gases are substantially fully combusted in a combustion preheating zone I together with combusting air, and gases causing any bad odor are also fully combusted or decomposed. High temperature combustion gas not involving harmful gas flows partly into the shunt passageaway 6 at a location of a partition wall 4 and is exhausted from an exhaust tube 10 while the remaining gas flows in the preheating zone II.

Title: Cassette holder device
Inventor: KASAMI HIROYUKI
IPC: G11B15/675
Filed: 1983-12-08
Abstract: PURPOSE:To stop a cassette holder at an optimum position in a cassette loading/ unloading mode regardless of a fact whether the cassette type VTR main body is stored in an adaptor or not. CONSTITUTION:An operator releases a stopper when a cassette holder put into a cassette holder 13. Thus a lift arm 16A is turned toward an arrow (f) around a shaft 13F by the force of a bucket spring 14A. Therefore the revolving power toward an arrow (e) is produced at a part of a shaft 17E owing to a link structure of the arm 16A, the holder 13, a holder bracket 17A and a holder arm 18A. Then the holder 13 moves relatively away from the bracket 17A. While a detection pin 32 of a detection part 30 receives no external force and therefore the arm 16A continues its revolutions round the shaft 17E and then stops at a moment when a pawl part 16A at the tip of the shaft 17E is hooked to a pawl part 19a of a control lever 19. Then the movement of the holder 13 is stopped when the lower side 13a of a cassette take-out port of the holder 13 is set at the same height of a cabinet 60 of the VTR main body 10.
