摘要： PROBLEM TO BE SOLVED: To expand the degree of freedom of designing by forming a solar cell on the reverse side of a clock dial. SOLUTION: A total of 25 solar cells 12 (each five solar cells vertically and horizontally) are formed on an alumina substrate 11 that is in 6 inch square and × 0.2 mm thickness. The alumina substrate 11 has a 50% visible light transmittance. The solar cells 12 are divided into four portions by a cross split line and four stages are connected in series. An indium tin oxide transparent conductive film with a film thickness of 1000 Å is formed on the substrate 11. Then, a photoresist is formed in an electrode shape by the photolithography process. Then, p-i-n type amorphous silicon lamination is formed by the plasma CVD method and the solar cell parts 12 are formed by the photolithography process and the reactive ion etching method. Then, a counter electrode that also plays a role of the reflection plate of incidence light to the solar cells 12 is formed. An epoxy resin where carbon black powder is mixed is applied to the entire batteries 12 with a film thickness of 50 μm for covering and is burned to form a protection film 13.

摘要： PROBLEM TO BE SOLVED: To obtain the product of a compression-molded bonded magnet having a high mechanical strength by compression molding a magnet compound composed only of magnet powder or of magnet powder and a slight amount of binder resin, and then impregnating the molded body with the binder resin in a vacuum. SOLUTION: After a magnet powder has been compression-molded into a molded body having a prescribed size under a prescribed pressure without adding anything, the molded body is impregnated with an epoxy resin in a vacuum and hardened under a prescribed heating condition. The vacuum impregnation is performed, in such a way that the molded body is dipped in a two-part epoxy resin contained in a glass beaker, and the beaker is deaerated in a vacuum desiccator so that the molded body may be impregnated with the resin. Then the impregnated molded body is returned to the atmosphere, and the excessive epoxy resin adhering to the surface of the molded body is removed by cleaning the surface with isopropyl alcohol. Since the epoxy resin is not added at the time of compression-molding the magnet powder, the density of the SmCo bonded magnet thus manufactured is improved. Therefore, the characteristics of the magnet are improved and an adequately strong strength is obtained, because the molded body is impregnated with the epoxy resin.

This composite magnetic powder is compressed and molded together with a binder in the magnetic field. Moreover, it is also possible to use composite magnetic powder obtained by mixing anisotropic NdFeB system magnetic powder of 50 to 500mum and anisotropic Sm2Co17 system magnetic powder of 10mum or less and composite magnetic powder obtained by mixing anisotropic Sm2Co17 system magnetic powder of 50 to 500mum and SmFeN system magnetic powder of 10mum or less. Thereby, the filling density can be raised and a magnet having higher characteristic can be obtained.

摘要： PURPOSE:To obtain a thin film magnetic head having excellent characteristics by patterning a magnetic film by a lift off method in which a plating layer of a metallic material having the higher solubility in an acid soln. than the magnetic film is used. CONSTITUTION:A 'Permalloy(R)' film 20 is deposited as an underlying film for plating on an insulating substrate 10. A positive type photoresist 30 is then coated thereon and is so patterned that magnetic pole parts remain. A frame 40 consisting of the Zn film is completed if the resist 30 is removed. An amorphous Co-Nb-Zr film is next formed as the magnetic film 50 over the entire surface, then the magnetic film is divided to a peak face 41 of the frame and the 'Permalloy(R)' and the frame 40 is formed. Only the frame 40 is dissolved when the entire part of the substrate 10 is immersed in an aq. hydrochloric acid soln. The film 50 deposited on the peak face 41 is simultaneously lifted off and removed and the film 50 patterned to the magnetic poles remains. The magnetic poles are completed by finally etching off the film 20 except the magnetic pole pattern. The magnetic film having excellent soft magnetic characteristics is patterned with high accuracy according to the above-mentioned method.

摘要： PURPOSE:To improve the adhesion strength of a transparent oxide film to Ag, by incorporating specific amounts of Ge or Ga to Ag or Ag alloy at the time of applying the coating of a transparent oxide film of Al2O3, etc., for the purpose of preventing the sulfide discoloration of Ag or Ag alloy. CONSTITUTION:Since the product of Ag or Ag alloy is easily sulfidized in the air and discolored, a hard film consisting of transparent oxide such as Al2O3, SiO2, Ta2O5, etc., is formed on the above the sputtering method in order to prevent the above-mentioned sulfide discoloration. This transparent oxide film is inferior in the adhesive strength to Ag or Ag-alloy product, so that, prior to the application of the transparent oxide film of Al2O3, etc., Ge or Ga is incorporated by 0.5-10wt% to an Ag or Ag-alloy matrix. In this way, oxides of Ge or Ga are allowed to exist between the surface of Ag base metal and the transparent oxide film, and, owing to the presence of these oxides, the adhesive strength of the transparent oxide film to Ag metals can be remarkably improved.

摘要： PURPOSE:To improve productivity and reproducibility by installing glass substrate on which a lower electrode and iridium hydroxide film are patterned in a reaction chamber and laminating successively a tantalum pentaoxide film, tungsten trioxide film and upper electrode by CVD on said substrate. CONSTITUTION:Ta2O5, WO3 and upper ITO electrode are continuously formed by a plasma CVD method on a substrate on which a lower ITO electrode and Ir(OH)n are preliminarily patterned. Ta(OC2H5)5 is introduced with gaseous H2 as a carrier gas into a vacuum chamber and a gaseous mixture composed of Ta(OC2H5)5-H2 and an equal amt. of gaseous O2 are introduced therein to form a Ta2O5 film. WCl6 is then introduced likewise with H2 as a carrier gas into the chamber to form WO3 by making the mixing ratio with O2 as 15SCCM (WCl6-H2):10SCCM(O2). A gaseous mixture composed of In(C2H5)3-H2 at 19 SCCM, a gaseous mixture composed of Sn(OCH3)4-H2 at 2SCCM and O2 at 15SCCM are introduced with H2 as a carrier gas into the chamber to form ITO. The film formation by such CVD method is excellent in productivity, reproducibility of element characteristics and ease of process automation.

摘要： PURPOSE:To make selection of displays easy and to prevent uneven displaying by having the 1st transparent conductive film layers consisting of many segments on one outer side of constituting layers, and the 2nd transparent conductive film layer as a common electrode on the other outer side and applying voltage between the segments of the 1st transparent conductive film layers thereby transferring electric charge within the same plane to obtain the intended display patterns. CONSTITUTION:The 1st transparent conductive film layers 12, 12', tungsten trioxide thin film layers 13, 13', tantalum oxide layers 14, iridium oxide layers 15, 15' and the 2nd transparent conductive film layer 16 are formed in respective patterns on a transparent substrate 11. In this stage, the display patterns 13, 15 are formed as a pattern A, and 13', 15' as a pattern B and both patterns are formed into the same shape. When the pattern A is driven by ordinary driving and is held open at the point of the time when the pattern is colored, the pattern A exhibits a memory characteristic in the colored state. Thereafter, when plus voltage is applied to the pattern A and minus voltage to the pattern B, the pattern A changes to a decolored state and the pattern B to a colored state. In other words, the phenomenon in which the coloring electric discharge migrates from the pattern A to the pattern B is confirmed.
