Abstract: Three links (40) within one width-direction unit (54) are included in respectively different link units (46). The links in the first row and the sixth row from the right end and the left end of a chain are included in the same link unit (first link unit 46-1). The links in the second row and the fifth row are included in the same link unit (second link unit 46-2). The links in the ninth row and the tenth row are included in the same link unit other than the link unit in which the links in the second row and the fifth row are included (first link unit 46-1 or third link unit 46-3). With the above structure, the stress amplitude of the links forming a chain for a chain-type continuously variable transmission can be reduced.

Abstract: The fixing device includes a fixing member heated from inside; and a pressing member forming a fixing nip with the fixing member. A toner image transferred on a sheet is heated and pressed so as to be fixed on the sheet at the fixing nip through which the sheet is nipped and conveyed. The fixing member includes, on an inner circumferential surface thereof, a heat absorbing layer containing heat-conductive fillers oriented in a direction intersecting with a conveying direction of the sheet.

Abstract: A chain (endless flexible member) is looped over an input pulley and an output pulley. Each of the input pulley and the output pulley includes a pair of a fixed sheave and a movable sheave. The fixed sheave and the movable sheave have tapered faces that are opposed to each other to define a V-shaped groove. A vibration damping plate (vibration damping member) is fixed to each fixed sheave, and is in contact with the outer peripheral face of the fixed sheave. When the fixed sheave vibrates, the vibrations are damped by the friction between the outer peripheral face of the fixed shave and the vibration damping plate.

Abstract: In a hub unit of a bearing module, an outer end face of an attachment flange of an outer ring in a vehicle lateral direction is located further outward in the vehicle lateral direction than a point of a load applied to the outer ring from rolling elements located on an outer side in the vehicle lateral direction. A fitting surface for determining a radial position of the outer ring with respect to an inner periphery defining a supporting hole is formed on an outer periphery of an insertion portion. An inner edge of the fitting surface in the vehicle lateral direction is located further inward in the vehicle lateral direction than a point of a load applied to the outer ring from the rolling elements located on an inner side in the vehicle lateral direction.

Abstract: An image forming apparatus includes an image carrying member, a transport belt, a driving roller, a transferring member, a nip portion, and an applying portion. The transferring member makes contact with the inner circumferential surface of the transport belt to press the transport belt against the image carrying member. The nip portion is formed between the transport belt and the image carrying member by the pressure of the transferring member. The applying portion applies a bias to the transferring member. Application of the bias to the transferring member causes, at the nip portion, the toner image carried on the image carrying member to be transferred to the recording medium carried on the transport belt. Near the nip portion, a pair of support members are arranged which keeps both width-direction end parts of the transport belt in contact with the image carrying member.

Abstract: A dust cover disposed on an outer periphery of an outer ring member of a bearing unit has a generally disc shape as viewed from an axial direction of the bearing unit. The dust cover has an outside ring portion, a short cylinder portion that extends toward an outboard side from an inner peripheral edge of the outside ring portion, and an inside ring portion that extends radially inward from a distal end of the short cylinder portion. A partition that restricts entry of muddy water into a vicinity of a seal member located on the outboard side is provided on an upper portion of an outer peripheral face of the short cylinder portion of the dust cover. A drain opening through which the muddy water is drained to an outside is formed in the short cylinder portion, at a position on an inboard side of the partition.

The image forming apparatus includes an image carrier including an image carrying surface to form an electrostatic latent image; a developing device which supplies the toner to the image carrying surface to form a toner image; and a suction device configured to create airflow for suctioning the toner scattered from the developing device. The developing device includes a duct configured to guide the airflow to the suction device. The duct includes a connection surface, to which the suction device is connected, and a suction surface provided with suction ports into which the toner flows. The suction ports aligned in a direction apart from the connection surface include different suction ports in ventilation area.

Abstract: A chain, wound to span between two pulleys each having facing conical surfaces able to change a distance therebetween and sandwiched by the facing conical surfaces, includes: link units each configured such that plate-shaped links, each having openings, are oriented in a chain circumferential direction and arranged in a chain width direction; and pins each extending through the openings of the links of the link units adjacent in the chain circumferential direction and each contacting the conical surfaces of sheaves at both ends thereof. A curvature radius of a shape curve representing a shape of each end face of each pin in a plane perpendicular to the chain circumferential direction is larger at an inner side in a pulley radial direction than at an initial contact point that is a contact point at the time when a load on each pin is 0.

The difference in surface hardness between each sprag (4) and each of an inner ring (2) and an outer ring (3) is set to be larger than a hardness of Rockwell C-scale HRC0 and to be equal to or smaller than HRC15.

Abstract: A unicast-use tunnel is added between the Note-C and GW-B (i.e., a unicast optimization). Then, the Note-C transmits, to a GW-C, a second IP packet encapsulating a first IP packet, to which an inter-GW header is added, by an IP header to which a multicast address is set. The multicast-use second IP packet is transferred to a CE by way of a tunnel. The CE copies the received second IP packet and transfers it to a GW-A and the GW-B by way of the tunnel (i.e., a multicast optimization).
