Abstract: An information processing device includes a categorizing section and a display control section. The categorizing section extracts a material component image identified as a material component from plural images obtained by imaging a sample fluid containing plural types of material element, and categorizes the extracted material component image serving as a detected component by predetermined category. The display control section performs control to re-categorize a material component image serving as the detected component already categorized into a different category, such that, when selection of a movement destination category is received in a state in which a first image list of detected components is being displayed, in a subsequent state in which the first image list and a second image list for the movement destination are being displayed at the same time, a material component image selected from the first image list is moved to the second image list.

Abstract: A centrifugal compressor is equipped with a housing including a suction passage which accommodates an impeller. The suction passage is provided with a first opening portion formed at a position facing the impeller, a second opening portion formed on an upstream side of the first opening portion, a circulation flow path which allows the first opening portion and the second opening portion to communicate with each other and extends in an annular shape around a rotational axis of the impeller, and a plurality of guide vanes disposed in the circulation flow path. The circulation flow path includes a first region in which a plurality of guide vanes is disposed at intervals in a circumferential direction, and a second region in which no guide vane is disposed. The second region extends over a wider range in the circumferential direction than the interval between the guide vanes in the first region.

Abstract: In a silent chain transmission, a silent chain composed of uniform link plates meshes with a sprocket having two or three kinds of teeth randomly distributed around its circumference. The teeth have a common tooth gap bottom diameter, and a uniform angular spacing, but have different heights and different tooth forms.

Abstract: Link plates of a silent chain are produced by first shaving the inner surfaces of the connecting pin holes, the sprocket tooth-engaging surfaces, and the backs of the link plates, and then forming dimples on those surfaces by shot-peening.

Abstract: In a silent chain, a link plate is formed by punching, followed by simultaneous shearing of the inner surfaces of the pin holes, the inner engagement surfaces of the teeth, the outer engagement surfaces of the teeth, the connecting arc continuous with the inner connecting surfaces, and the back of the link plate over at least 70% of the plate thickness. The plates are arranged at random to form a link, and engage a sprocket first by engagement of an inner engagement surface with a sprocket tooth, and thereafter seat on the sprocket with outer engagement surfaces of the link teeth in engagement with the sprocket teeth.

Abstract: In a double-sided engagement type silent chain in the form of an endless loop, the outermost link plates of the link rows whose outermost plates are not fixed to the chain's connecting pins, have teeth protruding toward the outside of the loon, and are paired in side-by-side relationship with adjacent inner link plates whose teeth protrude toward the inside of the loop.

Abstract: To reduce seizing in a tensioner having a plunger slidable in a plunger-accommodating hole of a tensioner housing and biased in the projecting direction, the tensioner housing is formed of a hyper-eutectic Al—Si series alloy containing Si in the range from 14 to 16 weight % and having a particle diameter of proeutectic Si in the range from 20 to 30 ?m.

Abstract: In a silent chain for an automobile engine timing drive, the pins which interconnect the link plates of the chain have a vanadium carbide layer formed on their surfaces by diffusion penetration. The vanadium carbide layer is composed of two parts: an inner part, on the steel base material of the pin, being a V8C7 layer, and an outermost part being a V2C layer.

Abstract: Connecting pins in a roller chain are chromized by a diffusion penetration treatment, that results in inner and outer chromium carbide layers on the steel base material. The inner layer contains Cr7C3, and the outermost layer, which is thinner than the inner layer, contains Cr23C6. The surface roughness of the outer layer is reduced by barrel polishing, without removal of all of the Cr23C6-containing layer.

Abstract: In a silent chain, back surfaces of the link plates of a guide link row, a non-guide link row, or both, are formed with concave, arc-shaped portions having radii of curvature shorter than the minimum radius of curvature of the chain-contacting region of a chain guide shoe. The minimum height of the back surface of link plates having concave back portions is greater than the minimum distance between the inner tooth flanks and the nearest pin holes, and the minimum distance between the outer tooth flanks and the nearest pin holes.

Abstract: A roller chain, in which when the roller chain comes into contact with guide members, the contact area is reduced, so that frictional resistance is decreased and friction loss generated during transmission of power is reduced. A roller chain is formed such that an outer link assembly comprising a pair of outer link plates and an inner link assembly comprising a pair of inner link plates are alternately connected along the pitch line of the chain to each other by pins. The distance from the pitch line of the roller chain to outermost edge surfaces of the link plates is the backside height. The backside height of the outer link plates is lower than the backside height of the inner link plates. When the roller chain contacts and slides on the guide members, the outer link plate does not come into contact with the guide members so that friction loss can be reduced. In some embodiments, some of the link plates are concave ellipsoidal (gourd-shaped) and others are non-concave ellipsoidal (cucumber-shaped).

Abstract: In a silent chain, the joint row link plates and the connecting pins are subjected to barrelling to improve the smoothness of their contacting surfaces and thereby achieve improved lubrication by an oil film. The edges of the pin holes in the plates are also rounded or chamfered by barrelling to reduce contact pressure when the joint row plates become tilted relative to the connecting pins.
