An object of this invention is to provide such a welded structure of and welding method for two metallic parts fitted together at a tubular section in a high-pressure fuel supply pump, that enables rapid joining of both metallic parts by staking (press-fitting included), screw fastening, and / or laser welding, offers high welding strength and sufficient fluid sealability, and keeps the metallic materials free from thermal changes in composition. While an electric current is supplied to any one of the welding connection surfaces formed between a pump housing and cylinder in a high-pressure fuel supply pump, between the pump housing and an installation flange, between the pump housing and an intake or discharge joint, between the pump housing and a pulsation-absorbing damper cover, between the pump housing and a relief valve mechanism, and between the pump housing and an electromagnetically driven intake valve mechanism, the particular two sections are pressed against each other to generate, along the connection surface, a plastic flow not causing melting or fusion due to heat, and form a diffusion-weld region at the connection surface by using the plastic flow and the application of the pressure.

[Problem] To provide a knitted tricot fabric having a high fabric strength and a low cost, which is to be used in a female member of a hook-and-loop fastener, exhibits a large engagement force with an engaging element and, in the case where said knitted fabric is engaged with engaging elements located on both sides thereof, shows no difference between the engagement forces in both directions. [Solution] A knitted fabric for hook-and-loop fastener, which is a knitted tricot fabric consisting of a knitting yarn in the front face part, a knitting yarn in the middle part and a knitting yarn in the back face part, wherein the knitting yarn in the front face part, the knitting yarn in the middle part and the knitting yarn in the back face part are each provided with loops formed at definite intervals, the loops formed in the knitting yarn in the front face part are connected with the loops formed in the knitting yarn in the middle part, and the loops formed in the knitting yarn in the middle part are connected to the loops formed in the knitting yarn in the back face part. In the knitted tricot fabric, a same number of piles are formed by the knitting yarn in the front face part alternately from side to side, and the knitting direction of the loop-forming knitting yarn in the front face part is opposite to the knitting direction of the loop-forming knitting yarn in the middle part while the knitting direction of the loop-forming knitting yarn in the middle part is opposite to the knitting direction of the loop-forming knitting yarn in the back face part.

A monolithic ceramic electronic component includes a component body and outer electrodes. The component body includes a plurality of stacked ceramic layers and a plurality of inner electrodes which extend between the ceramic layers, which contain Ni, and which include exposed ends exposed on predetermined surfaces of the component body. The outer electrodes are electrically connected to the exposed ends of the inner electrodes and are formed on the predetermined surfaces of the component body by plating. The inner electrodes include Mg—Ni coexistence regions where Mg and Ni coexist.

It is possible to provide a light modulator using a thin plate having a thickness of 20 mum or below capable of stably holding a conductive film suppressing troubles such as resonance phenomenon of microwaves in a substrate and pyro-electric phenomenon. It is also possible to provide a method for fabricating the light modulator. The light modulator includes: a thin plate (10) formed of a material having a photoelectric effect and having a thickness of 20 mum or below; light waveguide (11) formed on the front or rear surface of the thin plate; and modulation electrodes (13, 14) formed on the front surface of the thin plate for modulating light passing through the light waveguide. The light modulator further includes a reinforcing plate (16) bonded to the rear surface of the thin plate and a conductor film (17) formed on the side surface of the thin plate continuously to the side surface of the reinforcing plate.
