摘要:
A method of fragmenting a DNA sequence having a starting size of at least 10000 base pair into fragments having a mean size smaller than or equal to 1300 bp, wherein the DNA sequence is put in a solution, the solution comprising the DNA sequence is put in a container and the container is placed in a liquid bath which is subjected to the action of ultrasound waves such that the ultrasound waves travel through the liquid bath to excite the container and the solution so as to shear the DNA sequence, and wherein the ultrasound waves have a frequency falling in the range between 28 kHz and 80 kHz.

摘要:
A grid interconnection device includes a relay controller configured to control separation or interconnection of a relay; a receiver configured to receive, from a predetermined transmission path, power failure information containing at least local area information indicating an area in which a power failure occurs; a determination unit configured to determine an occurrence of a power failure in a power distribution system, when the power failure information includes local area information of an area to which the power distribution system belongs; and a detector configured to detect an islanding state. The detector increases detection sensitivity of the islanding state when the determination unit determines the power failure in the power distribution system. The relay controller performs separation control for the relay when the islanding state is detected by the detector.

The grid interconnection device connected to the bank where alternating-current power is transmitted and to the power supply device provided to a customer includes: a detector detecting start of the alternating-current power transmission based on a state of the alternating-current power; a receiver receiving a grid interconnection start instruction for starting grid interconnection between the bank and the power supply device; and a grid interconnection controller controlling the bank and the power supply device to be interconnected or separated, in which the grid interconnection controller starts grid interconnection between the bank and the power supply device upon receipt of the grid interconnection start instruction in a state where the start of the alternating-current power transmission is detected.
摘要:
A digital camera includes an interface connected with a memory card. To the memory card is recorded an image file including a compressed main-image data and compressed thumbnail image data of a subject taken. When the operator selects a transmit mode and performs predetermined key operation, the image file recorded on the memory card is transmitted to an Internet server via a communication circuit. After completing the transmission, the image files already transmitted are erased leaving the compressed thumbnail image data.
摘要:
A resin composition utilizing coated resin moldings, the resin composition comprising 100 parts by weight of a crushed material of coated polyolefin resin moldings compounded with from 3 to 15 parts by weight of an ethylene polymer having a weight average molecular weight of from 50,000 to 180,000.
摘要:
A synthetic resin composition comprises an aqueous medium, a surfactant, and a resin and filler dispersed in the aqueous medium by the surfactant. The surfactant comprises a first high molecular weight compound having a weight-average molecular weight of at least 10000 and a second high molecular weight compound having a weight-average molecular weight of not less than 150 and less than 10000. In the synthetic resin composition, a solid material is well dispersed and the viscosity doesn't remarkably increase even if a solid content is increased. So, the increased amount of a non-volatile matter may be used and the storage stability improves. Further, flame retardation, deodorization, heat resistance and light fastness also improve. In addition, an interior material which is a fabric coated with the synthetic resin composition is provided. In the interior material, the texture, flame retardation, deodorization and light fastness improve without the deterioration of workability.
