Carrier for a conveyor system

Motor module for a conveyor system

A linear conveyance device includes a conveyance carrier and a stator-side platform. The conveyance carrier includes: a conveyance carrier main structure; a first roller and a second roller; a mover-side magnetic element that drives the conveyance carrier main structure with respect to the stator-side platform; and a mover-side counter moment generating element that generates a counter moment against overturning of the conveyance carrier between the mover-side counter moment generating element and the stator-side platform. The stator-side platform includes: a first rail that engages with the first roller; a second rail that engages with the second roller; a stator-side magnetic element paired with the mover-side magnetic element to generate a magnetic attraction force in a horizontal direction; and a stator-side counter moment generating element that generates the counter moment between the stator-side counter moment generating element and the mover-side counter moment generating element paired therewith.

Linear conveyance device

From the viewpoint of a decrease in environmental impact in recent years, an object of the present invention is to effectively utilize lignin as a circulative biomass resource having high effect of reducing environmental impact. Specifically, the object is to provide a lignin derivative that can improve the dispersibility of various substances to be dispersed regardless of uses of cements, dyes, oil field drilling mud, and the like. The present invention provides a lignin derivative compound that is a reaction product of a lignin sulfonic acid-based compound with an aromatic water-soluble compound, and a dispersant containing the same. The lignin derivative compound preferably has an anionic functional group and/or a polyalkylene oxide chain.

Lignin derivative compound and use thereof

A linear transport apparatus includes a transport cart, a first roller that rotates about a first rotation shaft extending from the transport cart along a first direction, a second roller that rotates about a second rotation shaft extending from the transport cart and forming an acute angle with the first rotation shaft, and a rail sandwiched between the first and second rollers to extend along a track on which the transport cart moves. The rail includes a first contact portion coming contact with the first roller and restricting movement of the transport cart in a second direction perpendicular to a direction in which the rail extends and the first direction, and a second contact portion that comes into contact with the second roller and is parallel to the second rotation shaft, and the rail includes a portion in which curvature of the track moves is different from another portion.

Linear transport apparatus

A composition including: a lignin sulfonic acid-based compound and a water-soluble compound; a lignin derivative that is a reaction product of the lignin sulfonic acid-based compound with an aromatic water-soluble compound; or the lignin sulfonic acid-based compound, the water-soluble compound, and the lignin derivative. The composition is a granular product or a liquid product.
