Abstract: PROBLEM TO BE SOLVED: To prevent deterioration caused by radiation heat when an insulative sealing film is to be formed continuously by forming an optical element consisting of a laminate of a light emission region and electrode under the vacuum film forming conditions, and forming a conductive sealing film while vacuum state is retained. SOLUTION: By means of mask evaporation, an ITO transparent electrode 5 of 100nm thick, a TPD hole conveying layer 4 of 500nm thick, Alq3 light emission layer 3 of 50nm thick, and LiAl alloy metal electrode 1 of 2kÅ thick are laminated in the sequence as named on a glass board 6 in a patten of picture element dots so that an organic EL element is formed. The evaporation mask is replaced within the same vacuum chamber, and a conductive sealing film 7 of gold of 10kÅ thick is put as enclosing the surfaces of the picture element dots consisting of laminate of the transparent electrode 5, hole conveying layer 4, light emission layer 3, and metal electrode 1. Further the evaporation mask is replaced in the same vacuum chamber, and an insulative sealing film 8 of SiO2 of 2kÅ thick is put as enclosing the conductive sealing film 7.  Likely deterioration of the organic layer at this time caused by the radiation heat is reduced by existence of this film 7.

Title: Illuminance distribution adjusting device in lens scanning type optical system of copying machine
Inventor: HARADA MASAAKI
IPC: G03G15/04
Filed: 1979-06-29
Abstract: PURPOSE: To correct the decrease in the quantity of light on a photoreceptor caused by the movement of the lens and make the illuminance on the photoreceptor even by using a shield plate.  
     CONSTITUTION: A shield plate 5 is provided between the slit 3 and lens 2 of the lens scanning type optical system A. As this shield plate 5 goes away from the central axis B of an original platen 1, the quantity of light on a photoreceptor 4 decreases as shown in the figure on account of the COS 4  law of the lens 2. Thereupon, the decrease in the quantity of light is corrected by the shield plate 5. When the lens 2 is on the central axis of the original platen 1 (position of 2a), the shield plate 5 shields the central part of the lens and as the lens 2 goes away from the central axis B of the original platen (the positions of 2b, 2c), the area of the lens 2 shielded by the shield plate 5 is decreased, whereby the decrease in the quantity of light by lens scanning is corrected.

Title: Method for forming polycrystalline silicon film
Inventor: KAMIDATE SHINICHI
IPC: H01L23/52
Filed: 1987-04-01
Abstract: PURPOSE:To improve the breakdown-strength characteristic of an oxide film, by intermittently supplying material gas, and laminating and forming a plurality of polycrystalline silicon layers, in which the diameters of crystal grains in each layer gradually increase toward an upper region from a lower region. CONSTITUTION:Monosilane is intermittently supplied in two times, end a polycrystalline silicon film is formed. This film is divided into two layers, i.e., an upper polycrystalline silicon layer and a lower polycrystalline silicon layer. Namely, the crystal growth in the upper layer is performed again independently from the crystal growth in the lower layer. Therefore, the diameter of the crystal grain in the upper layer becomes smaller than that in the conventional grain. An oxide film, which is formed on said polycrystalline silicon film, is formed in the upper polycrystalline silicon layer. Then the interface between the polycrystalline silicon and the oxide film is positioned in a region, in which the diameter of the crystal grain is small. The degree of asperity appearing at the interface becomes small. Thereby, the breakdown strength of the oxide film 1 can be improved.
