Abstract: Provided are a gear in which oil film formation between the tooth surfaces of gears rotating at high speed can be effected to a sufficient degree, in which generation of pitting, abrasion, and scoring is prevented, and which helps to prevent an increase in temperature and wear to achieve an improvement in durability, and a gear drive unit. A multitude of minute concave recesses are provided at random on a tooth surface, and an average area of the recesses is set to a range of 160 to 740 ?m2. Accordingly, the tooth surface can obtain a high oil film forming capacity. Thus, even under a low-viscosity/thin-lubrication condition in which the thickness of the oil film is extremely small, it is possible to achieve a long service life.

The driver circuit includes a pulse generating circuit for generating an output signal at the output terminal. The pulse generating circuit has a first and second differential input stage for respectively driving a push-pull construction of output transistors in response to the input pulse signal supplied through the input signal terminal with respect to the push-pull output, whereby to simplify the circuitry, operate at a high slew rate, and decrease electric current consumption.

Abstract: Provided are a gear and a gear drive unit which allow oil film formation to a sufficient degree between tooth surfaces of gears rotating at high-speed and which help to prevent generation of pitting, abrasion, and prevent scoring, temperature rise, and wear to thereby achieve an improvement in terms of durability. A tooth surface is provided with a multitude of minute recesses arranged at random, in which an axial surface roughness parameter Ryni of the surface thus provided with the recesses is set to a range: 0.8 ?m?Ryni?2.3 ?m. As a result, the tooth surface is endowed with a high oil film formation performance, and it is possible to attain a long service life even under a low-viscosity/thin-lubrication condition in which the oil film is extremely thin.

Abstract: The present invention provides a planetary gear device that can prevent wear and seizing of a pinion gear and a carrier, has few components, and of which assembly is not complicated. In the planetary gear device of the invention, a pinion gear 14 is supported such as to rotate freely by an outer circumferential surface of a pinion shaft 13 with a needle roller 15 interposed therebetween. The pinion shaft 13 is fixed between a pair of carriers 11 and 11. A hard coating including a diamond-like carbon is formed on surfaces of the carriers 11 and 11 facing both end surfaces of the pinion gear 14 and the needle roller 15. Wear and seizing can be prevented as a result of the hard coating even when the end surfaces of the pinion gear 14 and the needle roller 15 come into sliding contact with the surfaces of the carriers 11 and 11 during operation of the planetary gear device. Because the number of washers 16 can be reduced, the number of components can be reduced and complicated assembly can be reduced.

Abstract: An object detection apparatus has a laser radar and near infrared ray projector. The projector has a near infrared ray projecting lens, a laser oscillator, a laser receiver and a swivel actuator. The laser oscillator emits a laser beam, while the swivel actuator scans the laser beam in a laser scanning range. A laser receiver receives the laser beam reflected on an object. The near infrared ray projecting lens diverges the laser beam and projects a near infrared ray into a range including the laser scanning range and a near infrared ray projecting range. The near infrared camera obtains an infrared image by receiving a near infrared ray reflected on the object. An electronic control unit calculates object information based on the received laser beam when detecting an object and causes the near infrared ray to be projected to obtain the infrared image when acquiring the infrared image.
