摘要： In a high-voltage transformer, an insulating ring is placed on and along the inner surface of the core housing, and gaps are formed between the tips of the flange-like plates of the coil bobbin and the inner side of the insulating ring. With such a construction, the gaps and the insulating ring are provided between the coil bobbin and the inner wall of the core housing, so that the flange-like plates of the coil bobbin do not come in contact with the inner surface of cylindrical wall of the core housing. Therefore, a surface distance of the coil bobbin ranges to a contact surface of the coil bobbin where it comes in contact with the front wall of the core housing. The surface distance is elongated. The voltage drop by the creepage discharge does no occur.

摘要： In a spark plug, a nickel-alloyed center electrode has a front end which has a constricted end forming a spark gap with a ground electrode by way of a noble metal firing tip. The noble metal firing tip is secured to a front end surface of the constricted end by applying a laser beam welding to an interface between the constricted end and the firing tip all through their circumferential length so as to form a wedge-shaped welding solidification portion.

摘要： A gas sensor having a laminate structure composed of thin sheets of solid electrolyte and including a cavity portion 21 and an oxygen concentration cell 5. The oxygen concentration in the cavity portion 21 is held constant. The oxygen concentration cell 5 includes an active electrode 12 having a relatively high catalytic capability with respect to NOx or combustible gas and an inner common electrode 13/15 (serving as an inactive electrode and an oxygen-concentration-sensing electrode) having a relatively low catalytic capability with respect to NOx or combustible gas. The oxygen concentration cell 5 is disposed in the gas sensor so as to be exposed to the interior of the cavity portion 21. The concentration of NOx or combustible gas is determined based on an electromotive force (of the order of mV) generated between the active electrode 12 and the inner common electrode 13/15 by a concentration cell effect.

摘要： A split-flow-type flowmeter in which an end portion of a flow splitter tube 1 is inserted into a main-flow pipe 10 having a diameter D. A flow splitter tube 1 includes a U-shaped split-flow passage 1a. A detection element is disposed at a bottom portion (not shown) of the U-shaped split-flow passage 1a. The split-flow passage 1a assumes a flow path structure symmetrical with respect to a plane passing through the detection element. A flow inlet 2a and a flow outlet 2b of the split-flow passage 1a face in mutually opposite directions along the flow direction of the main-flow pipe 10 and open symmetrically at the same position on the flow cross section of the main-flow pipe 10. In order to divert into the split-flow passage 1a a portion of relatively high flow rate of flow from the main-flow pipe 10, the center of opening of the flow inlet 2a/flow outlet 2b is positioned between the center of the flow cross section of the main-flow pipe 10 and an average-flow-velocity position at which flow in the main-flow pipe 10 is of an average flow velocity, as observed on the flow cross section of the main-flow pipe 10.

摘要： A flow measurement device is disclosed, in which an accumulation of pollution substance onto a detection element is prevented, and which can measure a reverse flow similarly to a normal flow. On both ends of an outer wall 23 outer peripheral portion of a divided flow pipe 20 having a &OHgr;-shape pipe passage, there are oppositely formed an inlet port 25 and an outlet port 26, which open in faces orthogonal to a flow direction of a main flow M that is a detection object. Within the divided flow pipe 20, by a curved partition 27, plural branch flow passages 28a, 28b mutually branching and joining in the divided flow pipe 20 are formed. Inside both end portions of the outer wall 23, undulation portions 32, 33 are formed so as to clog an inlet and an outlet of the outer peripheral side branch flow passage 28a and, by this, throttles are formed respectively in a flow passage between the inlet port 25 and the inlet of the branch flow passage 28a and a flow passage between the outlet port 26 and the outlet of the branch flow passage 28a. In a bottom portion of the outer wall 23 of the divided flow pipe 20, a detection element 31 is attached so as to be exposed to a flow in the outer peripheral side branch flow passage 28a and, against its detection face, a down flow DW further divided from a divided flow D obliquely impinges.
