摘要:
In a toroidal-type continuously variable transmission including input and output side disks and a pair of power roller bearings, rolling elements of the power roller bearings are made of a steel which is to be case hardened, a medium-carbon steel or a high-carbon steel which is such a steel as containing carbon in an amount of 0.2 wt % or more, and are subjected to a carbonitriding process and hardening and tempering treatments. The toroidal-type continuously variable transmission has a long life by improving the rolling life of the power roller bearings, the input side disks, and the output side disks.

In order to prevent strong bending stress given to outer rings of thrust ball bearings of power roller assemblies and to improve the durability of the outer rings, a toroidal-type continuously variable transmission has thrust needle bearings which absorb thrust load given to the outer rings as well as allow the outer rings and corresponding trunnions to be shifted from each other. Preferably, the entire circumference of the pitch circle of the balls of each thrust ball bearing overlaps with a load-absorbing region, which is one or more annular and/or arcuate regions having the same width as the needles of needle bearings radially arranged in said regions in order to absorb thrust load.

A toroidal-type continuously variable transmission provides an input side disk disposed on an input shaft, an output side disk disposed on an output shaft, and a power roller for transmitting motive power of the input shaft to the output shaft while engaging both the input side disk and the output side disk, in which the input side disk, the output side disk, and the power roller made of a material are subjected to either a carburizing and grinding process or to a carbonitriding and grinding process so that effective carburized depths of the input side disk, the output side disk, and the power roller are limited to a range between 2.0 mm and 4.0 mm. The toroidal-type continuously variable transmission is capable of improving not only the rolling contact lives of the traction surfaces of the input and output side disks as well as the traction surfaces of the power rollers, but also the fatigue fracture lives of the input and output side disks and power rollers.

To provide an electronic apparatus that can prevent electronic components from being separated from a circuit board.The electronic apparatus 10 includes a circuit board 25, an electronic component 28 mounted on the circuit board 25 via solder balls 26, a cover member 30 mounted on the circuit board 25 so as to surround and cover the electronic component 28 and a convex portion 34 provided at the top plate portion 32 of the cover member 30. The convex portion 34 is deformable to a second state protruding on the circuit board 25 side from a first state protruding in the direction opposite to the circuit board 25 side. When the convex portion 34 is deformed in the second state, the convex portion 34 thus deformed can be made in contact with the top portion 28a of the electronic component 28.

There is provided a liquid crystal display capable of decreasing the number of components and easily carrying out an assembly. When a liquid crystal body 13 is to be attached to an opening 12 of a housing 11, the liquid crystal body 13 is supported and attached to the housing 11 by means of a plate portion 16 provided in parallel with the opening 12 through a wall portion 15 on a back side 11a of the housing 11. In this case, a flexible board 14 drawn from an end face of the liquid crystal body 13 is pulled out of an insertion hole 17 provided on the wall portion 15. For this reason, it is not necessary to provide a holding member in the attachment of the liquid crystal body to the housing as in the conventional art. Therefore, it is possible to decrease the number of components and to reduce an attachment man-hour of the holding member.

A three-dimensional shape measuring apparatus capable of simultaneously obtaining range information and luminance information with high precision, independently of an object. A controller scans slit light, emitted from a laser beam source and shaped by a cylindrical lens, on an object plural times, by mirror surfaces of a polygon mirror, while causing the laser beam source to flash by using a laser beam source driver. The slit light is time-sequentially combined into projection pattern light having plural light stripes, respectively 3-level or more intensity-modulated, and the projection pattern light is projected onto the object. An image processor obtains the range information and the luminance information based on reflection light obtained by image pickup by first and second cameras.

A replaceable ink cartridge has a body for storing the ink; an ink outlet for supplying the ink into a recording head; an air communicating port for communicating with an atmosphere; a peripheral portion around the ink outlet; a peripheral portion around the air communicating port; a seal member for removably sealing the peripheral portion around the ink outlet and the peripheral portion around the air communicating port. The replaceable ink cartridge has a structure that is formed so as to strip the seal member off from the peripheral portions of the ink outlet and the air communicating port in a manner that the air communicating port is opened at first and the ink outlet is opened at second.
