摘要： PROBLEM TO BE SOLVED: To form a multilayer film having extremely high adhesive on a resin material surface. SOLUTION: A mixed layer 12 of a gradient compsn, in which a carbide forming element and its carbide are mixed and a carbide content is reduced as it is away from a substrate 11, is formed on the resinous substrate 11 and the most upper layer 13 is formed on a surface of the mixed layer 12. As compsn. differentiation in a boundary of the substrate 11 and the first mixed layer 12 is extremely small, an adhesive strength between the substrate 11 and the multi-layered film 10 becomes to extremely high.

摘要： PURPOSE:To suppress the generation of a noise radio wave through reduction of the generation of a capacity discharge current by sufficiently generating preliminary micro-discharge in prior to main discharge. CONSTITUTION:An electrode for preventing a noise radio wave comprises an electrode parent material 1; and a mixture film 2 with which the electrode base material 1 is covered and which consists of a resistor 21 of a metallic oxide and a dielectric 22 of a metallic oxide. At least on the surface of the mixture film 2, the dielectric 22 is formed in a needle-like state extended approximately vertically to the surface of the electrode base material 1 and uniformly dispersed. In prior to main discharge generated between the resistor 21 and a counter electrode anode, preliminary microdischarge is frequently generated between the two phases of the dielectric 22 and the resistor 21, and along therewith, a main discharge voltage can be reduced. This constitution causes effective reduction of a capacity discharge current causing the generation of a noise radio wave.

摘要： PURPOSE: To ensure the surface of a substrate to be made rough without breaking the substrate so as to enable a highly adhesive coating film to be formed on the surface. CONSTITUTION: A 1st process to form a coating film 2 on the surface of a substrate 1, and a 2nd process to form unevennesses on the surface by peeling the film 2 off the surface to effect peeling part of the substrate off the substrate together with the film 2, are conducted in this order. By this method, the surface of the substrate 1 can be assuredly made rough without breaking the substrate 1, thus enabling a highly adhesive spray coating film 4 to be formed on the rough-surfaced substrate.

摘要： PURPOSE:To provide a method for producing a corrosion resistant muffler for attaining noise absorption and sound insulation by filling and outer pipe provided on the outer periphery part of an outlet pipe with a noise absorbing material without the fusion loss of the noise absorbing material, and by bending and welding works in a production process. CONSTITUTION:In an outer pipe attaching process, the other end of an outer pipe 8 with its one end opened is fixed to the periphery of the small hole opened part 4 of an outlet pipe 4. In a frame assembling process, an inlet pipe 1 and the outlet pipe 4, are attached to an inner plate 6 and an outer plate 5 disposed in a muffler, and inner pipes 2 and 3 are attached, if necessary. In a coating process, the front and back surfaces of a member forming a frame are coated with a corrosion resistant material and burnt. In a noise absorbing material filling process, a part between the outlet pipe 4 and the outer pipe 8 is filled with a noise absorbing material 9. In an outer pipe diameter reducing process, the diameter of one end of the outer pipe 8 is reduced. In a final process, an outer shell is cylindrically attached to the periphery of the frame.

摘要： PURPOSE:To avoid stick slip, delay in action, the occurrence of scuffing and the like by preventing a spool from being hydraulically locked. CONSTITUTION:A thin film 100 made of titanium nitride is formed over the outer circumferential surface of the second land section 62 of a spool 58 in such a way as to be thin at the side of a control pressure port 78, but to be thick at the side of a first low pressure port 74. Since a clearance between the outer circumferential surface of the second land section 62 and the inner circumferential surface of a valve port 52 is large at the control pressure 78 side, but small at the first low pressure port 74 side, unbalance liquid pressure in the direction correcting eccentricity takes place in the circumference of the second land section 62 when the spool 58 is one-sided, so that the occurrence of hydraulic lock is thereby prevented. This constitution thereby allows the spool 58 to be smoothly slid in response to the degree of the excitation of a coil 106, and the liquid pressure control of respective cylinders can be enhanced in accuracy.

摘要： PROBLEM TO BE SOLVED: To reduce the damage to a laminated oxygen sensor element having a ther mal spray layer. SOLUTION: A fusion spray layer 12 is formed on the surface of a sensor element 1, when the operating condition of a spray gun 15 is controlled on the basis of the set conditions that the temp. difference between the sprayed surface 14 and non-sprayed surface 17 of the sensor element 1 becomes below the specified value, or such a condition is established that the temp. difference between the sprayed surface 14 and non- sprayed surface 17 is maintained under the specified value (below 100 deg.C) by heating the non-sprayed surface 17 of the sensor element 1 using a heat source or temp. raising the two surfaces 14 and 17 simultaneously with the fusion spray heat through a thermo- medium, and thereupon fusion spray is conducted. A solid electrolyte sheet, base material sheet, and a plurality of atmospheric air introducing hole sheets to form atmospheric air introducing holes between them are laminated, and an exhaust side electrode and atmosphere side electrode on the atmospheric air introducing hole side are furnished on the two surfaces of the solid electrolyte sheet, and the atmospheric air introducing hole sheets are arranged so that the one farther from the solid electrolyte sheet and nearer the base material sheet has a greater adhering area.
