Abstract: An image reading apparatus of the present invention includes a first light source, a first light guide, a second light source, a second light guide, light receiving elements and a lens unit. The first light source emits first light. The first light guide directs the first light from the first light source toward an image-carrying object as first linear light extending in a primary scanning direction. The second light source emits second light of a wavelength different from that of the first light. The second light guide directs the second light from the second light source toward the image-carrying object as second linear light extending in the primary scanning direction. The light receiving elements are arranged in the primary scanning direction. The first and second linear lights are reflected by the image-carrying object, and the reflected lights are guided by the lens unit toward the light receiving elements.

Abstract: The first primer of the invention is a primer which, when used in PCR under appropriate conditions, serves to detectably amplify 16S rRNA-encoding DNAs of bacteria of the Escherichia, Salmonella and Vibrio genera, but when used in PCR under the same conditions, does not serve to detectably amplify either chloroplast 16S rRNA-encoding DNAs or mitochondrial 16S rRNA-encoding DNAs. The second primer of the invention is a primer which, when used in PCR under appropriate conditions, serves to detectably amplify 16S rRNA-encoding DNAs of Staphylococcus aureus and Bacillus cereus, but when used in PCR under the same conditions, does not serve to detectably amplify either chloroplast 16S rRNA-encoding DNAs or mitochondrial 16S rRNA-encoding DNAs.

Abstract: In a vehicle power steering device, a motor is turned on to rotate in one direction whether a steering wheel is turned clockwise or counterclockwise. A switching mechanism is interposed between a motor armature shaft and an output shaft to change directions of the output shaft rotation relative to the armature shaft rotation in response to turning direction of the steering. The switching mechanism may include electrically controlled coupling/releasing members or mechanically controlled rotation reversing and coupling mechanisms.

Abstract: In a starter with a planetary gear speed reduction mechanism, a first output shaft retaining member (retaining member 10, washer 20) and a second output shaft retaining member (pinion retaining ring 250) are mounted on an output shaft 220 in such a manner as to sandwich from axially front and rear directions a bearing support portion of a housing 400 which supports one end of the output shaft 220, so that a thrust load in the frontward and rearward directions of the output shaft 220 is received at the front and rear end faces of the bearing support portion of the housing 400. Therefore, the axially rearward movement of the output shaft 220 is regulated assuredly without regulating it by the rear end face of the center bracket 360 and the mortor partition wall 800, thereby preventing deformation of the center bracket.

Abstract: In a starter having a planetary gear reduction mechanism and a shock absorbing device, a first friction plate of the shock absorbing device is engaged with an internal gear of the reduction mechanism to restrict the internal gear from rotating. A space is provided radially between the internal gear and a housing to allow rotation of the internal gear upon application of an impact shock. A cylindrical member which is harder than the housing is disposed between the space relatively movably against the housing and the internal gear so that the internal gear is restricted from directly contacting the housing.

Abstract: In a starter, a planetary gear reduction mechanism has pins supporting planetary gears and directly fitted into an outer member of a one-way clutch. The outer member rotates with the revolution of the planetary gear. An internal gear engaged with the planetary gears is connected with a rotary disk of a shock absorbing device disposed on the outer periphery of the one-way clutch through a connecting member and an elastic member. The connecting member has engaging projections engaged with the elastic member within the connecting recess of the internal gear. The engagement projections are housed within the connecting recess with some clearance provided in the radial direction. The internal gear is thus held radially movably with respect to the rotary disk via the connecting member.

Abstract: A starter dynamo having a pinion engageable with a ring gear and an armature for rotating the pinion is supplied at engine starting with an electric storage power from an electric double layered capacitor used exclusively for the starter dynamo. With this storage power, the armature rotates and, with this armature rotation, the pinion rotates. An engine ring gear is driven through the pinion to start the engine. After the engine starting, the ring gear rotation is transmitted to the armature through the pinion and the starter dynamo charges the electric double-layered capacitor. Thus, an electric storage power required for the next engine starting is charged in a short period of time.

Abstract: A rotor 2 has a rotary shaft 20. A drive shaft 7 is provided around an outer periphery of rotary shaft 20 and is rotatably supported on a housing. Drive shaft 7 has the same axial center as rotary shaft 20, and has a pinion gear 7b meshing with a ring gear 8 of an engine. A speed-reduction mechanism 4 includes a sun gear 2b provided on rotary shaft 20, a planetary gear 4b meshing with sun gear 2b, and an internal gear 4a meshing with planetary gear 4b. A reduction shaft 5 receives a rotational torque transmitted from rotor 2 through speed-reduction mechanism 4. A first one-way clutch 6b is interposed between reduction shaft 5 and drive shaft 7 for connecting reduction shaft 5 to drive shaft 7 only when any rotational torque is transmitted from reduction shaft 5 to drive shaft 7. A second one-way clutch 6a is interposed between drive shaft 7 and rotary shaft 20 for connecting drive shaft 7 to rotary shaft 20 only when any rotational torque is transmitted, from drive shaft 7 to rotary shaft 20.
