Abstract: A stop switch assembly includes a movable block, a pressing portion, a driving rod, a driving pin and an elastic member. The movable block includes a first pair and a second pair of opposite side surfaces, a hole is defined in the movable block passing through the first pair of side surfaces and an inclined slot is defined in the movable block passing through the second pair of side surfaces. The driving pin is inserted in the driving rod with its head movably arranged in the inclined slot. The elastic member is arranged between the pressing portion and the movable block for applying an elastic bias to the pressing portion to allow the pressing portion being away from the movable block. When the pressing part is pressed, the driving pin slides in the inclined slot and drives the movable block moving between a first position and a second position.

Abstract: The present invention discloses an annular cooling device for large-scale cylindrical shell, which comprises a plurality of inner jet devices and outer jet devices; the inner jet devices are arranged inside the cylindrical shell along the inner periphery; the outer jet devices are arranged outside the cylindrical shell along the outer periphery; each inner jet device and each outer jet device are oppositely arranged; the inner jet devices are used for spraying cooling medium to the inner wall of the cylindrical shell; the outer jet devices are used for spraying the cooling medium to the outer wall of the cylindrical shell; and the spray ranges of each inner jet device and each outer jet device in the axial direction of the cylindrical shell are both greater than the length of the cylindrical shell.

Abstract: Two PARMS-SNP molecular markers for identifying resistant gene VrTAF5 of Vigna radiata (Linn.) Wilczek Cercospora leaf spot disease are provided, which belongs to the field of molecular genetic breeding. The two molecular markers PARMS-1517 and PARMS-10010 include SNP sites located at the 32622352 and 32613913 bases of Vigna radiata (Linn.) Wilczek chromosome 6 respectively. 240 bp sequence before and after the PARMS-1517 is shown in SEQ ID NO.1, a 131st position is SNP site, and a polymorphism is A/C; 240 bp sequence before and after the PARMS-10010 is shown in SEQ ID NO.2, a 117th position is SNP site, and a polymorphism is A/G. The PARMS-SNP molecular markers have a high specificity, accurate and reliable detection results, which can be used for rapid identifying Vigna radiata (Linn.) Wilczek Cercospora leaf spot disease resistant varieties, molecular marker-assisted selective breeding, and shortening a breeding period.
