Title: Device for detecting degree of congestion on platform
Inventor: SASAO ISAO
IPC: G06T1/00
Filed: 1990-07-27
Abstract: PURPOSE:To make the processing technique of the title device simpler so that the degree of congestion on a platform can be detected with a fewer number of pickup devices by calculating the degree of congestion by the door opened time of trains arriving at the platform. CONSTITUTION:This device for detecting degree of congestion on a platform is constituted of an A/D converter 2, a video memory 16 which always stores the latest image pickup data by successively storing image pickup data digitized by the converter 2 synchronously to video synchronizing signals, time measuring means 17 which counts the opened time of the door 14 of a train 13, and a degree-of-congestion calculating means 18 which calculates degree-of congestion data 15a from the door opened time of trains. Since the degree of congestion of a platform is calculated from the door opened time of trains arriving at the platform in such way, an image pickup device 1 can take the image of the door section of trains and the image pickup process required for the device 1 is only the discrimination of opened and closed states of doors. Therefore, the degree of congestion of a platform can be detected with a fewer number of image pickup device 1 and the processing technique can be simplified.

Title: Semiconductor light emitting device
Inventor: YAMAGOSHI SHIGENOBU
IPC: H01S5/34
Filed: 1982-11-12
Abstract: PURPOSE:To prevent mirror breakdown and thus contrive to stabilize the characteristic and improve the reliability by forming a window layer in accordance with the structure of a quantum well. CONSTITUTION:Under mentioned each layer 12-15 is successively formed on an N type GaAs substrate 11. An N type GaAs buffer layer 12 has the impurity concentration equal to that of the substrate 11, and an N type AlxGa1-xAs clad layer 13 has a forbidden band width larger than that of a well layer 14. The structure of a quantum well 14 is formed by alternately laminating e.g. well layers and barrier layers both in non-doping by means of GaAs for the well layer and AlxGa1-xAs for the barrier layer. By the way, the thickness of the well layer should be a de Broglie's wave length. A P type AlxGa1-xAs clad layer 15 is the same as the layer 13. In this constitution, the light generated in the well layer is confined in the layers 13 and 15 and then go toward a resonance mirror plane M caused by cleavage. The mirror plane M has the forbidden band width increased more than in the well layer, thus obtaining the effect of a window region.

Filed: 1981-12-12
Abstract: PURPOSE:To stabilize the ageing variation of a contactor resistance by superposing Al which contains TiN and Cu on an ohmic contact layer or a Schottky junction layer, thereby preventing a void from forming due to electromigration. CONSTITUTION:A window is opened at an SiO2 film 2 on a diffused layer 8 of an Si substrate 1, Ti 3 is sputtered in Ar, TiN 4 is superposed by a reactive sputtering method in atmosphere having Ar and N or 5:1 of pressure dividing ratio, is annealed at 450 deg.C in N2, Ti4Si3 is formed in the boundary between Si and Ti as an ohmic contact. Then, Al 7 which contains Cu is covered by a sputtering method on the TiN4. The range of containing Cu is 0.5-16wt%. According to this structure, Cu is segregated in Al grain boundary, thereby suppressing electromigration along the grain boundary. Accordingly, the production of voids can be prevented, thereby reducing the ageing variation in the contacting resistance. Since the TiN is interposed and Si diffusion is prevented from the substrate, the void in the substrate can be prevented, thereby obtaining stable electrode in large current.
