Abstract: A stator includes a stator-core having slots and teeth, and a back-yoke having convex and concave portions. The convex portions are partially inserted into the slots, and the concave portions receive the teeth. The teeth include tip portions whose circumferential widths become larger along a radial direction from the inside to the outside of the stator. The back-yoke includes convex portions whose circumferential widths become larger along the radial direction from the outside to the inside of the stator. The tip portions and the convex portions have substantially the same shape. The length of a joint portion between the tip portion and the convex portion, the circumferential width of the tooth corresponding to a tip surface of the convex portion, the width of a root portion of the tooth, and the circumferential width of the convex portion corresponding to a bottom face of the concave portion are substantially the same.

Abstract: A mode control section controls an image generation section to operate in a normal mode or a polarized light component reduction mode on the basis of a mode signal from a mode signal generation section to cause the image generation section to form a normal image or a polarized light component reduced image. When the possibility of occurrence of stray light is high, the imaging device automatically switches to the polarized light component reduction mode and when the possibility of occurrence of the stray light is low, the imaging device automatically switches to the normal mode. The polarized light component reduced image is obtained by reducing or eliminating stray light having a polarized light component, and the normal image is formed without reducing the stray light. Thus, the imaging device is capable of automatically switching between the two modes.

Abstract: A method of bonding dissimilar metals, a bonding structure formed by such a method and a bonding apparatus for performing such a method. The resulting bond is capable of preventing corrosion (e.g., electric corrosion) resulting from contact of the dissimilar metals and obtains a dissimilar material joint exhibiting anti-corrosive property and bonding strength at low costs. The method includes overlapping two materials made from dissimilar metals having a seal material interposed therebetween and discharging the seal material from a bonding interface and bonding the two materials in direct contact with each other.

Abstract: In a crawler frame in which legs in a center frame are formed from cast steel, a simple structure is achieved by reducing the number of components. To this end, the crawler frame, which has a center frame composed of a central frame section for supporting a swing bearing and legs located on the right and left sides of the central frame section; and track frames disposed on the sides of the distal ends of the legs, respectively, of the center frame, is designed such that each of the legs is bifurcated into front and rear leg sections and the front and rear leg sections are respectively formed from cast steel.

Abstract: A crawler frame includes a center frame and right and left track frames disposed at right and left sides of the center frame so as to extend in a back and forth direction, wherein legs for connecting a central frame section of the center frame to the track frames are formed from cast steel in order that washing can be easily done by reducing the amount of mud to be adhered to and deposited on the legs and in order that easy manufacture may be possible.

Abstract: A concave portion serving as an erroneous insertion prevention groove is provided on a bottom of a battery pack along a battery pack attachment direction and an engagement concave portion engaged with an engagement member is provided in a battery-mounting equipment, whereby the detachment of the battery from the battery-mounting equipment can be prevented.

Abstract: A polyphase sequentially joined-segment coil of a rotary electric machine and a production method thereof are provided. The coil is made up of a plurality of conductor segments joined in series. Each of the conductor segments a head projecting from a stator core, a pair of legs, and a pair of ends projecting from the stator core. The heads are of two types: a large-sized head and a small-sized head extending inside the large-sized head. This structure permits the length of the conductor segments in an axial direction of the core to be decreased and improves cooling capability of the machine and coil losses.

Abstract: A sequentially joined segment armature coil is provided which may be employed in an ac machine such as an ac motor or motor generator. The armature coil is equipped with three phase coils each of which is made up of a first and a second phase windings identical in number of turns. This structure permits the number of turns of the armature coil to be changed easily by changing a connection of the first and second phase winding between a series connection and a parallel connection or changing a connection of the phase coils between a star connection and a delta connection. The structure also enables terminal leads of the first and second phase windings of each of the phase coils to be collected and withdrawn outside the ac machine, thus facilitating ease of arrangement of the terminal leads.
