The stator of an electric rotating machine includes a stator core constituted of a plurality of split cores joined to one another in a ring, a plurality of phase windings wound around the stator core, and an outer casing to an inner periphery of which an outer periphery of the stator core is fitted with clamping margin therebetween. The outer casing is provided with a brim including at least two brim portions at least at one of axial ends thereof. The brim portions are spaced from each other in a circumferential direction of the outer casing and project in a direction receding from a center axis of the outer casing.

In designing supersonic aircrafts, a method of designing a natural laminar flow wing is provided which reduces friction drag by delaying boundary layer transition under flight conditions of actual aircrafts. A target Cp distribution on wing upper surface, suited to natural laminarization in which boundary layer transition is delayed rearward in desired Reynolds number states, is defined by a functional type having as coefficients parameters depending on each spanwise station, a sensitivity analysis employing a transition analysis method is applied to the parameters, and a search is performed for the optimum combination of parameters to delay transition rearward.

A waterproof connecting structure for a pipe for connecting an intake passage of an internal combustion engine and an external gas detector to convey gas into the intake passage. The structure includes a connecting space to which the pipe is connected and a partition wall formed between the intake passage and the connecting space. The connecting space has a larger diameter than the pipe. The partition wall includes an elongate hole for placing the interior of the intake passage and the connecting space in fluid communication. This configuration prevents intrusion of droplets drifting in through intake air and allows a high degree of freedom for location of the pipe.

To provide a synthetic resin bottle with a handle that can be manufactured at a low cost and can be used reliably, a synthetic resin bottle with a handle includes a bottle; and a handle comprising a grip disposed at the upper rear portion of said bottle, an upper arm extending forward from the upper end of the grip, and a pair of lower arms that extends to the right and the left from the lower end of the grip and pinch body of the bottle from both sides. The fore-end of the upper fitting arm is fitted to neck ring formed in the lower portion of neck of the bottle and is secured firmly by undercut engagement with the neck ring, and wherein fore-ends of the pair of the lower arms are fitted to bases of a pair of raised portions disposed on both sidewalls of the body of the bottle similarly by the undercut engagement with the raised portions.

A heat transport device includes a container having a hollow structure including a fluid channel, at least one thermal-receiver heat exchanger and one thermal-radiator heat exchanger arranged side-by-side on an outer wall of the container along the fluid channel, and driving heat exchangers at respective terminal portions of the container. In this heat transport device, both ends of the fluid channel are closed to prevent intrusion of external air, and a liquid and a gas are sealed in the fluid channel. The driving heat exchangers cause the liquid to oscillate in the container along the internal fluid channel. The heat transport device provides low acoustic noise performance, improved temperature controllability, high heat transportation and heat radiating capacities, and improved heat transfer and fluid flow characteristics.

A slip ring apparatus includes a pair of slip rings electrically insulated from each other and disposed coaxially, a pair of electric conductive elements for providing electric connection between the pair of slip rings and a field coil of an automotive alternator, and an insulating member for holding the pair of slip rings and the pair of electric conductive elements. The electric conductive elements have at least one deformation absorbing portion for absorbing a deformation of the electric conductive elements.

A rolling bearing with sensor has an inner ring, an outer ring, rolling elements rollably disposed between the inner ring and the outer ring, a sensor provided on one of the inner ring and the outer ring and a detection member provided on the other of the inner ring and the outer ring radially opposed to the sensor which is adapted to be sensed by the sensor. A first retaining member is fixed to the outer ring end surface of the outer ring and retains one of the sensor and the detection member. A second retaining member is fixed to the inner ring end surface of the inner ring and retains the other of the sensor and the detection member. At least one of the inner end surface and the outer end surface is arranged so as to be pressed axially without the sensor or the detection member.

In a rotor of an AC generator for a vehicle, a coil bobbin, around which rotor coil is wound, includes a bobbin body having a first through hole at a winding drum portion and is made of hard resin. A first hole member is kept at the first through hole and is made of good thermal conductivity rubber. An outer peripheral layer is formed integrally with the first hole member and is made of good thermal conductivity rubber covering the outer peripheral surface of the winding drum portion. An improved rotor of an AC generator for a vehicle is provided, in which a regular winding property of the rotor coil is improved and at the same time, heat of the rotor coil can be more effectively radiated to the rotor core side so that generator output can be improved.

A steam drying apparatus in which a process chamber is fitted at a loading opening with a lid which is closed from above. The inner side wall surface of the process chamber has a first surface formed in the lower part thereof and is substantially in parallel with the inner wall surface of the lid, and a second surface extending from the upper end part of the first surface and bent outwards to face the inner wall surface of the lid. The second surface is provided with a steam supply port for supplying the processing solution vapor into the process chamber. To the steam supply port is connected a steam supply means for supplying the processing solution vapor into the process chamber.
