Title: Ink recording head
Inventor: ICHINOSE SUSUMU
IPC: B41J2/16
Filed: 1980-05-30
Abstract: PURPOSE:To prevent the spread of a meniscus and to improve a response property of ink jet, by a method wherein a material, which has a property being nonaffinity with ink, is applied to a front surface of an ink jet orifice in an electrostatic acceleration type ink jet recorder. CONSTITUTION:The electrostatic acceleration type ink jet recorder records such that a large number of electrode plates are mounted at an internal surface of an orifice 1 of an ink jet head, and ink in the orifice 1 is jetted through the selective application of a high-voltage pulse between said electrodes 3 and a facing electrode 4 at the inside of a record paper 5. In said ink jet recorder, a material 8 (for example, an oily material if ink is aqueous, or an aqueous material if ink is oily), which has a property being nonaffinity with ink, is applied to a front surface of an upper plate 2a and a lower plate 2b, which form the orifice 1, or at the side of the record paper 5. This permits the prevention of a spread of an ink meniscus.

Abstract: PURPOSE:To obtain a high light use efficiency by arranging an optical integrated detecting element consisting of a prescribed prism in the optical path of semiconductor laser light to increase the quantity of light to a recording medium and that to a signal detecting system. CONSTITUTION:An optical integrated detecting element 20 is arranged on the optical path through which the light emitted from a semiconductor laser 16 goes toward an optical disk 19. An optical waveguide layer 23 is formed on a substrate 21 of the detecting element 20 with a buffer layer 22 between them, and photodetectors 24a to 24d are connected to this layer 23.

Filed: 1990-03-26
Abstract: PURPOSE:To obtain good lighting property by having rhenium metallic layer formed on the surface of a base metal and heat-treated to form a gradient function material layer composed of rhenium metal and base metal on the surface of the base metal. CONSTITUTION:A rhenium(Re) layer 12 is formed by a plating technique on the surface of a base metal 11 composed of bar tungsten (W). The metal 11 to which the Re layer 12 is applied is heat-treated in a vacuum to diffuse W and Re with each other, so that part of the Re layer 12 enters into the metal 11 to form a gradient function material layer. In this way, the Re layer 12 which has poorer hydrogen adsorptivity than the base 11 is formed on the surface of the metal 11, therefore to allow the release of hydrogen gas, which is adsorbed to an electrode, at starting. As a result, lighting malfunction hardly occurs and good lighting property can be expected.

Title: Method for chromizing treatment
Inventor: MURAYAMA JIYUNICHIROU
IPC: C23C10/58
Filed: 1980-05-31
Abstract: PURPOSE: To restrain the alloying of Fe in a base metal with Cr and obtain excellent workability and corrosion resistance by a method wherein an Ni film having a predetermined thickness is previously formed on a surface to be treated, when chromizing the surface of carbon steel or alloy steel.  
     CONSTITUTION: An Ni film having a thickness of more than 5 is formed on the surface of a carbon steel (0.22% C, 0.25% Si, 0.52% of Mn) or SUS410 steel (0.07% C, 0.40% Si, 0.51% Mn, 0.06% Ni, 11.5% Cr). Then the surface thus coated with Ni film is subjected to the chromizing treatment. If the Ni film is absent, the alloying of Cr with Fe in the base material proceeds during the chromizing treatment, readily resulting in the formation of a brittle phase. On the other hand, when the Ni film is provided in advance, the alloying of Cr with Fe is inhibited and excellent workability and corrosion resistance can be obtained.

Title: Alloy excellent in resistance against wear and heat
Inventor: OOHASHI TAKAYUKI
IPC: C22C38/54
Filed: 1979-06-13
Abstract: PURPOSE: To provide an alloy which has a soft and hard mixed structure and excels in resistance against wear and heat and is appropriate to the valve moving parts of an automobile engine or the like, by causing iron to contain prescribed quantities of Cr, B, C, Co and Ni.  
     CONSTITUTION: An alloy is composed of 10W45wt% of Cr, 0.5W4.0wt% of B, 0.2W1.5wt% of C, 5W50wt% of at least one of Co and Ni and the rest of Fe and unavoidable impurities. Even if the alloy is only cast, large amounts of chromium boride and chromium carbide of high hardness are educed in the matrix of the alloy. Therefore, the resistance of the alloy against wear and heat can be heightened without causing the alloy to contain expensive W. The alloy can be applied as a building up material and is very effective for parts which would suffer from drastic wear.
