A spark plug (1) includes an insulator (2) and a metal shell (3), including a middle section (41) positioned between a collar section (16) and a tool engaging section (19). The middle section (41) has a bulged section (42), a first slender section (43) and a second slender section (44) that is the most slender at a portion positioned further to the leading end side than the bulged section (42). In a cross-section including the axis CL1, when the distance between both slender sections (43) and (44) along the axis CL1 is F (mm) and the bulged amount to the inside in diametrical direction of a most bulged section (42M) with respect to an imaginary line that connects a portion that is positioned furthest to the inside in diametrical direction of both slender sections 43 and 44 is G (mm), the relationship 0.00

A fixing device includes an endless belt and a belt holder contacting and rotatably supporting each lateral end of the endless belt in an axial direction thereof. A first protection ring and a second protection ring are interposed between the endless belt and the belt holder in the axial direction of the endless belt and rotatable in accordance with rotation of the endless belt to protect each lateral end of the endless belt as the endless belt is skewed in the axial direction thereof and brought into contact with the first protection ring. A friction coefficient between the first protection ring and the second protection ring is smaller than a friction coefficient between the first protection ring and the endless belt.

An image forming apparatus includes a fixing device. The fixing device includes a rotatable endless fixing member, a nip forming member arranged inside the fixing member, a pressing member in contact with the nip forming member via the fixing member, and a heating source configured to heat the fixing member. When an abnormality occurs in at least one of the fixing device and other devices included in the image forming apparatus, a rotation of the fixing member is stopped prior to stopping a rotation driving of a discharging unit and, after stopping, the fixing member is controlled to rotate.

A thermal printer includes a first thermal head, a first platen roller, first biasing means, a second thermal head, a second platen roller, and second biasing means. The first thermal head, the first platen roller, the first biasing means are in contact with a heat-sensitive layer of thermal recording paper. The second thermal head, the second platen roller, and the second biasing means are in contact with a heat-sensitive layer of the thermal recording paper. The second thermal head is arranged on the upstream side of the first thermal head in a paper feed direction. A paper feed speed of the first platen roller to the thermal recording paper is larger than a paper feed speed of the second platen roller. The first platen roller is in contact with the thermal recording paper while being more slippery compared with the second platen roller.

An electric vehicle drive system including an output member that is drive-coupled to a wheel, and a compressor connection member that is coupled to a compressor for an air conditioner. A drive power to be transmitted to the output member and the compressor connection member is generated by a rotating electric machine. The electric vehicle drive system further includes a wheel-driving rotating electric machine that has a rotor shaft drive-coupled to the output member and an air-conditioner rotating electric machine that has a rotor shaft drive-coupled to the compressor connection member through a second clutch. The rotor shaft of the air-conditioner rotating electric machine is drive-coupled to the rotor shaft of the wheel-driving rotating electric machine through a first clutch.

For an input interface apparatus for recognizing the motion of an object, there may be cases where the brightness of the object to be captured is insufficient, and thus, a camera takes an image of the object operated by the object, a depth position detector detects the position of the object based on captured frames, an action identifying unit identifies an action of the player based on a result on the detection of the object, an input receiving unit receives the action as an instruction to an input-receiving image displayed on a display, and in response to the action, an illumination control unit raises the brightness of the image projected on the display higher than that before the action is detected.

In a spark plug that has a small sized center electrode, enhancement of corruption-resisting property and heat-resisting property is promoted. The spark plug 1 includes a center electrode 5, an insulator 2 and a metal shell 3, and the insulator 2 includes a foot section 13, a tapered section 14 and a middle body section 12. The maximum outer diameter of a portion, which is arranged within the foot section 13, of the center electrode 5 becomes 3.0 mm or less. A step section 21 and a leading end side inner periphery section 51 are formed in the inner periphery of the metal shell 3 and the tapered section 14 is engaged to a step section 21. When A (mm3) is a volume of a portion of 2 mm of the insulator 2 from leading end of the insulator 2 toward the rear end side along the axis CL1 and B (mm3) is a volume of a portion of the insulator 2 from the rear end of the portion of the tapered section 14 which is engaged to the step section 21 to the leading end side and the portion is 1.5 mm or less of the diameter difference between the leading end side inner periphery section 51 and its outer periphery portion, 0.12≦A/B≦0.24 is satisfied.
