Abstract: A glow plug (100) includes: a housing (130) having a metal shell (110) and a cap unit (120); and a heater unit (150). A coupling member (180) is joined with the housing (130) and is also joined with the heater unit (150) at its edge portion (188), so as to enable the heater unit (150) to move along an axis line O and couple the heater unit (150) with the housing (130). When the edge portion 188 of the coupling member 180 is irradiated with a laser, at least part of the edge portion (188) melted by laser welding fills a gap (50) between the coupling member (180) and the heater unit (150) to form a welded part (210). As a result, even when there is a gap prior to welding, the weld strength between the coupling member (180) and the heater unit (150) can be maintained.

The heater unit has a large-diameter portion at the rear end thereof and a small-diameter portion frontward of the large-diameter portion and having a diameter smaller than the diameter of the large-diameter portion. The connecting member connects the small-diameter portion of the heater unit to the housing within the housing.

Abstract: A location information management system includes: a mobile station (30) that is located in a mobile communication network; and a service management server (40) that receives a movement sensing request to sense a movement of the mobile station (30) from a service providing server (50), the service management server (40) thereafter notifying the service providing server (50) that the movement of the mobile station (30) has been sensed upon an occurrence of the movement of the mobile station (30). The mobile station (30) receives first area information included in information that is periodically transmitted to each mobile station located in the area, the mobile station (30) thereafter sensing that the mobile station itself has moved upon receipt of second area information, and the mobile station notifying the service management server (40) that the movement of the mobile station itself has been sensed.

Abstract: Raw water G containing arsenic in an amount exceeding an environmental standard value is poured into a treatment bath filled with particulate carriers. The raw water G in the treatment bath is treated at a flow rate which does not allow production of ferric hydroxide in a suspended form in the raw water while adding an acidic iron solution to the raw water G so that the pH value of the raw water G is adjusted to 6.5-7.5. A ferric hydroxide membrane is produced on the entire surfaces of the carriers by contact oxidation reaction of dissolvable ferrous ions in the raw water G having the adjusted pH value, to cause the arsenic in the raw water G to be adsorbed on the ferric hydroxide.

Abstract: A glow plug (100) includes: a housing (130) having a metal shell (110) and a cap unit (120); and a heater unit (150). A coupling member (180) is joined with the housing (130) and is also joined with the heater unit (150) at its edge portion (188), so as to enable the heater unit (150) to move along an axis line O and couple the heater unit (150) with the housing (130).

A decline in detection accuracy can be prevented to the extent that combustion gas can be received by the leading end (72) of the convex portion (70) even if soot clogging should occur.

Abstract: A seal member (60) has a dual-tube structure consisting of an outer tubular seal member (160a) and an inner tubular seal member (160b); the outer tubular seal member (160a) is welded, at its rear end portion, to the inner circumferential surface of a forward-end housing (131), thereby forming a housing-side joint W2; the inner tubular seal member (160b) is welded, at its forward end portion, to a forward end portion of the outer tubular seal member (160a), thereby forming an inter-tubular-seal-member joint W3; and the inner tubular seal member (160b) is welded, at its portion located rearward of the joint W3, to the outer circumferential surface of the heater (10), thereby forming a heater-side joint W1. An action of pressing the heater forward is effected on the basis of an axial dimension L1 between the joints W2 and W1 shorter than an axial dimension between the joints W2 and W3 and is, therefore, mitigated.
