Title: Semiconductor light emitting device and its manufacture
Inventor: MOMOI HAJIME
IPC: H01L33/14
Filed: 1993-06-28
Abstract: PURPOSE:To provide a semiconductor light emitting device, especially, a surface light emitting type LED which has a light emitting layer of multiple quantum well structure and is suitable to a light source for optical communication. CONSTITUTION:In a light emitting layer 20 of an LED 100, an active layer of multiple quantum well structure is formed which is constituted by alternately laminating 8-15 layers of mixed crtstal films turning to quantum well layers 21 and mixed crystal films turning to barrier walls 22. The well layer 21 (Eg 0.92eV) and the barrier layer 22 (Eg 1.13eV) have P-type conductivity, and the layer width is 1.8nm or larger and 5nm or smaller. The discontinuous value E of energy level of the valence bands of the barrier layer 22 and the well layer 21 is 2kT (45meV) or smaller. Hence electrons and light positive holes easily pass the barrier layer, and heavy positive holes easily get over the barrier wall, so that the light emission in the barrier layer is restrained. Further the ratio of electrons existing in the lowest energy level in the quantum levels of the well layer increases, and the luminous efficiency is improved. The life of minority carriers in the well layer is shortened and the response speed is increased.

Abstract: PURPOSE: To raise the efficiency of dust collecting operation, by collecting dust contained in gas to be cleaned by granulating crushed coal being used as fuel.  
     CONSTITUTION: Coal a is crushed finely into proper grain sizes by means of a crusher 4. Crushed coal having grain sizes greater than a certain value b 1  and one having grain sizes smaller than that are separated from each other by a separator 5, and they are sent to a drier 6 seprately. Then, crushed coal b 1  having larger grain sizes is carried into a first dust collecting tank 11 of a dust collecting apparatus 7 via a first crushed-coal inlet port 9, while crushed coal b 2  having smaller grain sizes is carried into a second dust collecting tank 12 via a second crushed-coal inlet port 10. On the other hand, dust containing gas C 1  is introduced into the first and the second dust collecting tanks 11, 12 from a dust containing gas inlet 15 and passed through the layers of crushed coal b 1 , b 2 , and clean gas C 2  thus obtained is supplied from an outlet port 16 to a gas turbine system (not shown). Further, crushed coal d 1 , d 2  containing dust therein is carried into a gasifying furnace 18 via a dust separator 17 and used as fuel to be gasified. With such an arrangement, it is enabled to collect dust efficiently in an inexpensive manner.

Title: Automatic gate system
Inventor: KOSAKA SHINSUKE
IPC: G06Q50/00
Filed: 1991-06-28
Abstract: PURPOSE:To eliminate an inconvenience of showing a wireless card to a specific location by installing a parabola antenna where a primary radiator is provided at a focus of a reflection surface on a passage region and then transmitting and receiving an electric wave of a data for judging whether a passing person is allowed to pass or not. CONSTITUTION:A startup data passes through an interrogation data transmission block 3a from a data processing block 3d in an interrogator 3 and is converted to an electric wave and is discharged through a primary radiator 2 of a parabola antenna 1 on a passage region after conversion to the electric wave. When a passing person 4 shows a responsor 5 which is a wireless card horizontally to the antenna 1 within a passage region, it is fully irradiated to the radiated electric wave and the responsor 5 radiates a modulated electric wave immediately again. This electric wave is received by the radiator 2 which is located at the focus by a reflection surface of the antenna 1 and enters a queue data reception portion of an interrogator and then the response data is interpreted by a processing portion 3d. If the response data is proper, the passing person 4 is allowed to pass. On the other hand, if the response data is not proper, he is not allowed to pass, thus eliminating an inconvenience for showing the wireless card at a specific device.

Filed: 1990-06-16
Abstract: PURPOSE:To surely shield a necessary shielding position even if there are such circumstances as an article exists in the periphery, etc., by allowing section doors to descend slowly at least in a position being lower than height of refugees in case of fire. CONSTITUTION:In case fire is generated, it is sensed by the fire sensor 8, the hook 9 is tilted, and hooks of the ropes 10, 10 come to be detached from the hook 9. In such a way, when the hooks of the ropes 10, 10 are detached, support to a third section door 4 positioned in the lowest part is eliminated, therefore, its descent is started, and also, in connection with its descent, a first and a second section doors 2, 3 also start its descent. Also since the section doors 2, 3 and 4 descend slowly, refugees being in the vicinity in case where a fire is generated do not get hurt caused by colliding with the seconding section doors 2, 3 and 4, and can avoid them easily.

Filed: 1988-06-27
Abstract: PURPOSE:To enable measurement of a high potential/high temperature crucible at a low cost with a simple construction by connecting one end of a conductor to an earth wire through an ammeter while the other end thereof is arranged near the crucible. CONSTITUTION:One end of a conductor 2 as tungsten is connected to an earth wire through an ammeter 3 while the other end thereof is arranged near a crucible 1. When the tip of the conductor 2 is heated upto a high temperature by a radiation heat of the crucible 1, electron is released and attracted to the crucible 1 at a positive potential with respect to the conductor 2 to generate a current between the both. The intensity of the current is detected with an ammeter 3 to be taken into an arithmetic device 6, which computes a temperature of the conductor 2, namely, the temperature of the crucible 1. The results are shown on a display device 7. This eliminates the need for providing an insulating construction or the like and applying a high voltage to a thermocouple or the like.
