A compressor swash plate includes a base member having a flat plate shape, and a coating layer formed on a surface of the base member and having projections formed in a linear shape, in which the following inequalities are satisfied when a plane part formed on a prism is pressed against the coating layer with a pressure of 30 MPa: 0.01B0.06 and 10S40, where B indicates widths (mm) of surfaces of the projections in contact with the plane part, and S indicates a percentage (%) of a total sum of an area Si of the contact surfaces (a gross area of the surfaces of the projections in contact with the plane part) relative to a reference area (an area of a part of the coating layer against which the plane part is pressed).

A sliding contact surface-forming material, and method of making the material are disclosed, the material having minimal swelling and excellent friction-proof and wear-proof characteristics when used in moist environments such as in water, and improved in the friction-proof and wear-proof characteristics under dry friction conditions such as in the open air, particularly under oscillation conditions for testing journal. The material includes a reinforcing base impregnated with a resol-type phenolic resin having polytetrafluoroethylene resin dispersed therein. The reinforcing base is composed of a woven fabric formed by using, as each of the warp and the weft, a ply yarn which is formed by paralleling at least two strands of a single twist yarn spun from fluorine-containing resin fiber and a single twist yarn spun from polyester fiber, and by twisting them in the direction opposite to the direction in which the single twist yarns were spun.

A method for producing a pendulum arrangement of a pendulum laser device includes producing a universal joint of a pendulum of the pendulum arrangement by forming two orthogonal, at least partially micro-structured shafts via plastic injection moulding and positioning at least two bearing shells on the at least partially micro-structured regions of at least one shaft of the universal joint. The method further includes producing an optic carrier of the pendulum of the pendulum arrangement as a single piece with the bearing shells by overmoulding at least two bearing shells surrounding a shaft of the universal joint via plastic injection moulding. The optic carrier is connected to the universal joint such that it is configured to rotate about the one shaft.

A failure detection device includes a formaldehyde sensor that detects the generation of formaldehyde, a vibration sensor that detects vibration of a spindle head, and a machine controller that detects the occurrence of an abnormality of a spindle bearing. The machine controller determines the occurrence of the abnormality of the spindle bearing and a cause of the abnormality based on a change in the output value of the formaldehyde sensor over time and a change in the output value of the vibration sensor over time.

A rolling-element bearing includes a first ring element, a second ring element, a plurality of rolling elements rotatably disposed between the first ring element and the second ring element, and an electrically insulating layer on a surface of the first ring element.
