Insulators are respectively disposed such that longitudinal directions of trunk portions are oriented in a radial direction of teeth, and so as to place bottom surfaces of the trunk portions alongside two axial end surfaces of the teeth, concentrated winding coils are configured by winding conductor wires so as to be wound in multiple layers around the teeth so as to pass through a concave space that is formed by the trunk portions and first and second flange portions at two axial ends of the teeth, the second flange portion is disposed on an end surface of a core back of a stator core, and a temperature detecting element is installed by being inserted into an element insertion aperture that is formed on the second flange portion so as to be able to detect a temperature of a coil end of the concentrated winding coils.

Rotary electric machine

A fixing member () formed of an annular metal material is molded integrally with a connecting plate () to constitute a connecting plate structure (), said connecting plate () consisting of a plurality of bus bars () and a holder () for fixing and holding the bus bars. The fixing member () has an annular portion () touching a frame () for holding a stator (), and the connecting plate structure () is fixed to the frame () by the whole or a part of the surface of the annular portion.

Rotating electric machine

A connection member for supplying a stator winding with a current is constituted by covering a bus bar with a insulating resin. The bus bar is formed in an arc-like shape in the thickness direction of a belt-shaped conductor. Additionally, a weld zone formed on the bus bar has a projection portion projecting in the width direction, a first bent portion bent outside the arc from the projection portion in the thickness direction, and a second bent portion with the tip end thereof folded back in the width direction to allow the tip end of the second bent portion to be welded to a terminal on the stator winding.

Motor stator with improved connection member

An insulator includes: a trunk portion that is interposed between a tooth and a stator coil; and a first flange portion that is disposed on the trunk portion so as to be adjacent to the stator coil in a radial direction of a stator core. A notch portion is disposed on a flange protruding portion of the first flange portion that protrudes from the stator core in the axial direction of the stator core from an outer circumferential portion of the flange protruding portion toward the trunk portion. A holder that has a holder main body that is disposed on the notch portion is mounted onto the flange protruding portion. A temperature sensor is held between the holder main body and the stator coil.

The invention provides a projection display that achieves continuous light amount control with ease and without causing unevenness of illumination of light applied to a light valve responsive to a video signal, thereby allowing constant image display with satisfactory contrast. The projection display of the invention includes a light valve (); a light source () generating light applied to the light valve (); an integrator lens () provided on an optical path between the light source () and the light valve () and making uniform the illumination distribution of light applied from the light source () to the light valve (); and a light amount control system () provided on the optical path and including a turning mechanism () which turns like a set of double doors in order to adjust the amount of light applied from the light source () to the light valve (). The turning mechanism () is bent into a V shape in a direction to reduce the amount of light (to block the light).

A time management section is configured to change an output voltage in accordance with a temperature change characteristic of a lamp allowed to cool down. For restart of the lamp after the turn-off of the lamp, the lamp is cooled by a fan before the operation of turning on the lamp when it is judged that the temperature of the lamp is higher than a predetermined value, based on the output voltage from the time management section. The lamp is immediately turned on without the cooling of the lamp by the fan when it is judged that the temperature of the lamp is lower than the predetermined value.

It is an object to obtain a light source device and a projection type display device in which a fragment can be completely enclosed therein even if a discharge lamp bursts during lighting. During normal lighting of a discharge lamp ( ), an internal space of a light source device ( ) and an external space are spatially connected to each other through a vent hole ( ) formed on a cutoff valve mechanism ( ) and a vent hole ( ) formed on a concave reflecting mirror ( ). Cooling air is introduced and discharged between the internal space and the external space so that the discharge lamp ( ) is cooled down. When the discharge lamp ( ) bursts during lighting for some reason, a very strong impulsive pressure wave is generated in a moment of the burst. The pressure wave presses a movable valve ( ) provided in the cutoff valve mechanism ( ) through the vent hole ( ). By the pressing carried out with the pressure wave, the movable valve ( ) is pushed up in a direction of an arrow (K ), thereby closing the vent hole ( ).

A method of placing concrete into a steel encasement constructing an offshore structure. The steel encasement is erected. A plurality of first concrete injection holes are formed through the steel encasement in a heightwise spaced manner. The concrete is injected through the lowest disposed concrete injection hole into the erected steel encasement to a level below another concrete injection hole disposed just above said lowest disposed concrete injection hole. Then, the injection step is repeated in connection with a subsequent first concrete injection hole nearest to the level, to which the concrete has been placed, for placing the concrete into the steel encasement to a predetermined level.
