Cord provided with a tubular body

CORDÃO PROVIDO COM UM CORPO TUBULAR. Nos cordões convencionais com porções nodosas, tendo núcleo de borracha elástica, há uma diferença no grau de esticamento entre ambas as extremidades e o núcleo da porção nodosa. Portanto, há uma porção que é submetida a uma grande força de esticamento, e uma porção que não é submetida a nenhuma força de esticamento, e quando uma grande tensão se acumula na região entre as porções submetidas a diferentes forças de esticamento, a tensão atinge o limite e o cordão se rompe. A fim de resolver o problema acima, é provido um cordão tendo um corpo de cordão tubular feito de material elástico, compreendendo porções nodosas repetidamente colocadas em intervalos, cujo diâmetro varia dependendo da tensão na direção axial aplicada à mesma porção nodosa. CORD PROVIDED WITH A TUBULAR BODY. In conventional cords with knotted portions, having an elastic rubber core, there is a difference in the degree of stretch between both ends and the core of the knotted portion. So there is a portion that is subjected to a large stretching force, and a portion that is not subjected to any stretching force, and when a large tension builds up in the region between the portions subjected to different stretching forces, the tension reaches the limit and the cord breaks. In order to solve the above problem, a cord is provided having a tubular cord body made of elastic material, comprising knotted portions repeatedly placed at intervals, the diameter of which varies depending on the tension in the axial direction applied to the same knotted portion.

Lace provided with tubular lace body

A conventional cord having bulges is provided with an elastic rubber core and exhibits a difference in elongation or contraction between the rubber part corresponding to the end of each bulge and the rubber part corresponding to the center thereof.

The present invention is a cord provided with a tubular cord body that is made of a stretchable material and that has bulges which are repeatedly arranged with spaces thereamong and the diameters of which change in dependence on the axial tension applied to the cord body.

Information processing device

A digital coupon system (information processing device) consists of a database in which information on business operators and information on services provided by business operators are stored in association with each of a plurality of business operators, and a processor (control unit). When receiving a coupon issuance request from an Italian business division (a first business operator) that specifies a Thai business division (a second business operator) and a car sharing service (a second service) as a coupon issuance target related to a car lease service (a first service), the processor performs control to send a coupon to a user associated with the issuance target.

Technique for preparing universal humanised car19-dnt cells and application therefor

Provided are a technique for preparing universal humanised CAR19-DNT cells and an application therefor. Specifically provided are universal CAR-T cells targeting CD19, the universal CAR-T cells expressing an exogenous CAR construct, and the CAR construct having the structure shown in formula I: L-scFv-H-TM-C-CD3ζ (formula I); in the formula, L is nothing or a signal peptide sequence; scFv is an antibody single-chain fragment variable region sequence targeting CD19; H is nothing or a hinge area; TM is a transmembrane domain; C is a costimulatory signal molecule; and CD3ζ is a cytoplasmic signal conduction sequence derived from CD3ζ. The provided universal humanised CAR19-DNT cells have the advantages of low immunogenicity, not requiring gene editing to avoid GvHD, high safety, high specificity, and obvious tumour killing effects, and the provided construction method can be implemented in large-scale production, the production costs being low.

Sofa extension apparatus

Provided is a sofa extension apparatus. The sofa extension apparatus includes a sofa frame, extension brackets, a first linkage rod, a second linkage rod and a linear drive assembly. Each extension bracket includes a sofa fixing member and a leg portion extension assembly, the sofa fixing member is connected to the sofa frame, the leg portion extension assembly is rotatably connected to a front end of the sofa fixing member. Two ends of the first linkage rod are fixedly connected to rear ends of two sofa fixing members respectively. Two ends of the second linkage rod are connected to two leg extension assemblies respectively. The linear drive assembly is configured to drive the first linkage rod and the second linkage rod to move relative to each other, so as to enable the two extension brackets to be extended or retracted.

Adjustable bracket and high-feet sofa

Provided are an adjustable bracket and a high-feet sofa. In the adjustable bracket, the transmission rod (30) is in a straight rod structure. A first end (31) of the transmission rod (30) is connected to the fourth connection rod (213). A second end (32) of the transmission rod (30) is connected to the pedal rod group (10). The present application provides an adjustable bracket. In the case of the same sitting height, the adjustable mechanism of a sofa has a more compact structure so that the cleaning work of a mop, a vacuum cleaner, or a floor-sweeping robot is facilitated. Moreover, the height of the sofa from the ground is higher, making the sofa more attractive.

Seat Frame

A seat frame includes a base, a driving member and a stretching member. The driving member and the stretching member are disposed on the base. The stretching member includes backrest assemblies, cushion support assemblies and leg rest plate assemblies which are positioned on left and right sides of the base and set in pairs. A front end and a rear end of the cushion support assembly are hinged with one end of the backrest assembly and one end of the leg rest plate assembly respectively. When the seat frame is in a television (TV) posture and a lying posture, and the leg rest plate frame is inclined upward with respect to a horizontal plane.
