A rotating electrical machine () is driven by a three-phase AC current and is provided with a stator core (), a molded resin () for covering a coil wound on the stator core, a rotor core (), a shaft () provided to the rotor core (), a terminal base () provided to a coil end section, and a case () for covering the rotating electrical machine (). Power cables extending from the terminal base () are led out of the case () through a case terminal box (). A temperature sensor () is affixed in a hole in the molded resin () by the terminal base () and measures the temperature in the vicinity of a heat producing source.

In the stator, a thermistor housed in a tube is arranged to be sandwiched between a coil end and a U-phase bus bar, allowing the thermistor to receive heat from above and below at two faces, that is a face of the U-phase bus bar and a top face of the coil end. Moreover, the thermistor can be placed substantially in close contact with the coil end. Accordingly, the temperature followability by the thermistor can be realized at high accuracy. As a result, there can be provided a stator having a configuration in which temperature followability of high accuracy can be achieved in measuring the temperature of a coil of a stator using a temperature detection element, and that can correspond to further downsizing of a rotating electric machine.

A drowsiness detector detects the drowsiness by measuring a distance of an eyebrow at three points from a reference line defined by an inner eye corner and an outer eye corner. The three distances of the eyebrow from the reference line are respectively standardized by an inter-eye distance between the inner eye corners of the left and right eyes, and are respectively compared with thresholds for determining the rise of the eyebrow. The rise of the eyebrow is then translated as the start of the drowsiness, and is associated with an operation such as a doze prevention operation or the like.

A spark plugincludes an insulator, a metal shell, a center electrodeand a ground electrode. A spark discharge gapis formed between a front end portionof the center electrodeand the ground electrode. The metal shellhas a through holetherein and a metal convex portioninwardly radially projecting in the through hole. The metal convex portionincludes a convex rearward face, a convex inner circumferential faceand a convex forward face. The through holehas an inner diameter A (mm) at a front end side inner circumferential face, which is located at the front end side with respect to the convex forward face. The insulatoris inserted in the through holeand has a first insulator taper portion, a second insulator taper portionand a basebetween the taper portions. The present invention satisfies the following representations: G&#x2266;(A&#x2212;B)/2; A&#x2267;7.3; and 2&#x2266;XX&#x2266;4, where 'B' (mm) is an outer diameter of a border K between an insulator front end portion 38 and the second insulator taper portion, where 'G' (mm) is a distance of a spark discharge gap, and where &#x201c;XX&#x201d; (mm) is a length from a very-end portion FF of the convex inner circumferential faceto the border K in the axial Cdirection.

A sleep prevention system captures a facial image of a driver, determines a sleepiness level from the facial image and operates warning devices including neck air conditioner, seatbelt vibrator, and brake controller if necessary based on the sleepiness determination. A sleepiness determination device determines sleepiness from facial expression information such as distances between corners of a mouth, distance between an eyebrow and eye, tilt angle of a head, and other facial feature distances. The facial distances are calculated from captured images and from reference information gather during wakefulness. The sleepiness degree is determined based on the determination results including combinations thereof.

Device, program, and method for determining sleepiness

An apparatus for accurately determining a drowsiness level is provided. A doze prevention system includes a photographic apparatus, a drowsiness determination apparatus, and other apparatuses for doze prevention such as an alarm apparatus, a neck air conditioning apparatus, a seat belt vibrating apparatus, and a brake control apparatus. The photographic apparatus captures a facial image of a driver of a vehicle. The drowsiness determination apparatus determines a drowsiness level based on the facial image. The drowsiness determination apparatus uses a facial image captured by the photographic apparatus, detects a sign of drowsiness or a sign of struggle, and determines the drowsiness level based on the detection results.

Drowsiness determination apparatus, program, and method

A drowsiness alarm apparatus and a program for decreasing the possibility of incorrectly issuing an alarm due to an expressed emotion is provided. A wakefulness degree calculation apparatus performs a wakeful face feature collection process to collect a wakefulness degree criterion and an average representative feature distance. A doze alarm process collects a characteristic opening degree value and a characteristic feature distance. The wakefulness degree criterion is compared with the characteristic opening degree value to estimate a wakefulness degree. The average representative feature distance is compared with the characteristic feature distance to determine whether the face of the driver expresses a specific emotion. If the face expresses the emotion, alarm output is inhibited. When the face does not express the emotion, an alarm is output in accordance with the degree of decreased wakefulness so as to provide an increased alarm degree for the driver if necessary.

In a vehicle air conditioner, a case member of an inside/outside air switching portion is disposed at an approximate center in an interior unit in a vehicle width direction, to define an air passage extending in the vehicle width direction. An outside air suction port is provided in the case member, and first and second openings are opened in the case member at both side ends of the air passage in the vehicle width direction. One of the first and second openings is used as an inside air suction port, and the other one thereof is used as an outlet passage port. In addition, the outlet passage port of the case member is coupled to a suction port of a blower through a connection duct.

An ignition system for an internal combustion engine. At least one of a plurality of spark plugs and attached to each of cylinders A, B, B, and A is a self-cleaning spark plug A.

Ignition system for internal combustion engine

A spark plug (1) comprises a center electrode (5), an insulator (3), a metallic shell (2), and a ground electrode (6). The center electrode (5) comprises a body portion (12) having a cylindrical peripheral surface and a front-end-side opposing face (11) opposed in generally parallel to a side face of the ground electrode (6), and a protruding portion (15) which is protruded from the front-end-side opposing face (11) at a position decentered toward one side opposite to the ground electrode (6) with respect to a center axis line of the body portion (12) and which has a top face (14) formed generally parallel to the side face of the ground electrode (6). Then, given a length D of a line segment formed by an intersection that an imaginary plane including the center axis line of the body portion (12) and a center axis line of the ground electrode (6) intersects the front-end-side opposing face (11), and a protruding height h to which the protruding portion (15) protrudes from the front-end-side opposing face (11), a value of h/D is set to not less than 0.2. As a result, mixed air can be smoothly fed to around a spark discharge gap g, and moreover the flame extinction phenomenon becomes unlikely to occur. Thus, a spark plug superior in ignitability can be realized.
