Title: Manufacture of piston ring for internal-combustion engine
Inventor: SAGAWA JUNICHI
IPC: F02F5/00
Filed: 1985-08-02
Abstract: PURPOSE:To prevent brittleness and reduction in adhesion of a thermal spraying layer formed in an annular groove of a piston ring, by forming a plating layer having a nitriding preventing effect on the surface of the annular groove, and then nitriding the surface of the piston ring. CONSTITUTION:A piston ring 1 is formed with an annular groove along a central portion of an outer circumferential surface thereof. A plating layer 2 having a nitriding preventing effect is formed on at least a bottom surface of the annular groove. Then, a surface of the piston ring 1 is treated by nitriding to form a nitriding layer 3 on upper and lower surfaces and an inner circumferential surface of the piston ring 1. Then, a thermal spraying layer 4 is formed in the annular groove. Thus, since the nitriding is not carried out after the thermal spraying, there is no possibility that the thermal spraying layer 4 is embrittled by the influence of the nitriding. Furthermore, as the nitriding layer 3 is formed on the upper and lower surfaces of the piston ring 1, hardness and wear resistance of the piston ring 1 may be improved.

Filed: 1992-04-23
Abstract: PURPOSE:To enable the correct detection of a train position even with power failure by computing the position of a train through the collation of extracted data with the data of a storage means at the time of an extracting means extracting one cycle data. CONSTITUTION:When a train (a) approaches a reference loop P1 and a cyclic loop P2, detection signals corresponding to the loops P1, P2 are sent to a position decoder C from a code signal receiver 3b as the train (a) advances. The position decoder C includes a storage means ROM stored with reference data, an arithmetic processing means CPU, and an RAM for accumulating the above-mentioned detection signals. When the data by ten-bit part (one code) is accumulated in the RAM, the coincidence degree of this data with the reference data stored in the ROM is collated, and when the coincidence is obtained, the position of the train (a) is computed. In the case of contradiction such as power failure being generated to the incorporated data, the computation of the train position is resumed at the input time of ten-bit data from the following bit on.

Title: Water boiler
Inventor: HAMAKO YASUTAKA
IPC: F23Q25/00
Filed: 1980-12-04
Abstract: PURPOSE: To protect a cover plate and other parts of a boiler against deformation, by  supporting a flange formed at an opening of a combustion barrel and a cover plate for  the opening in a movable manner so that a clearance is formed therebetween by the  pressure in the combustion barrel when it is raised extraordinarily, and that combustion gas can be released with ease, for instance, when explosion is caused.   
     CONSTITUTION: When a burner 6 is combusted, combustion gas is carried through the  inside of a combustion barrel 5 and discharged from an exhaust pipe (not shown) by a  motor fan incorporated in the burner 6. In doing so, water in a boiler chamber 2 is  heated by the combustion gas through the wall of the combustion barrel 5. Here, a  cover plate 20 is fixed to a flange 5a formed at the opening end of the combustion barrel 5 by the intermediary of a packing 23 by means of screws 22 having tension springs 21. With such an arrangement, if internal pressure of the combustion barrel 5 is  increased extraordinarily due to explosive ignition, the cover plate 20 is forced open  against the force of the tension springs 21 to form some clearance between the flange  5a and the cover plate 20. Resultantly, high-pressure combustion gas can be released to  the outside, so that the cover plate 20 and other parts of the boiler can be protected  against deformation.

Abstract: PURPOSE: To reduce driving forces by causing a valve element freely movably disposed within a housing to be driven by rotary moments resulting from pressures, so that a plurality of valve openings are opened or closed, and enabling compensating moments canceling the rotary moments to be created. CONSTITUTION: When an electromagnet 12 is not excited, an armature 16 is energized downward by a spring 14 and a valve element 28 is held in a tilted condition via a ball 20, with a spigot projection 116 pressed into contact with a membrane 92 to close a valve opening 56. Next, when the electromagnet 12 is excited by a current that is half of a saturation current, the armature 16 is drawn upward and the valve element 28 is displaced into a horizontal condition by the force of a spring 26. Since the membrane 92 in that state is separated from the edges of the valve openings 56, 58, fluid from an inlet 46 flows toward an outlet 48.  When the electromagnet 12 is excited until being saturated, the valve element 28 is rotated clockwise by the spring 26 and a spigot projection 118 is pressed into contact with the membrane 92 so that only flow of the fluid toward the outlet 90 can be created.

Title: Optical waveguide and optical device
Inventor: INANAMI YOSHIHITO
IPC: G02B6/12
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To optimize a change in a refractive index difference Δn between a core and a clad by providing a refractive index changing region where the Δn changes with a region where the refractive index difference decreases monotonously and a region where the refractive index difference increases monotonously along the propagation direction of light. SOLUTION: The optical waveguide has the Δn changing region 121 at an exit end face 123. The Δn changing region 121 is so formed that the Δn changes with respect to the propagation direction (Z direction) of the light. The Δn of another region is formed constant always at the value of Δn1. The refractive index difference Δn at an exit end face 124 is changed to the Δn3 of the value smaller than the Δn1 in order to expand the mode diameter of the propagation light in the Δn changing region 121. At this time, the change in the Δn is once monotonously decreased to the Δn2 (Δn2<Δn3) from the Δn1 and is changed to be increased again up to the Δn3. The optical waveguide is formed by using polyimide which is controllable in refractive index by, for example, irradiation with electron beams.
