Abstract: 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.

Abstract: An electrical enclosure wherein an electrical component can be moved between various positions (e.g., connected, disconnected, test, etc.) without opening an enclosure door. The electrical enclosure supports a component for movement between a withdrawn position, a test position, and an inserted position. A handle is accessible by an operator from an exterior of the enclosure and is configured to move the component between the respective positions without having to open the enclosure. The handle is integral with the enclosure and thus an operator needs no special tool or other device to effect movement of the electrical component between its respective positions.

Abstract: The present invention provides a plate brick having a low amount of generation of smoke and a gas with a pungent odor during use, and exhibiting high durability. A plate brick of the present invention is obtained by: adding an organic binder to a refractory raw material mixture containing 0.5 to 20 mass % of aluminum and/or aluminum alloy; kneading the mixture with the organic binder; forming the kneaded mixture into a shaped body; and subjecting the shaped body to a heat treatment at a temperature of 400 to 1000° C., wherein the plate brick is obtained without being impregnated with a carbon-containing liquid material comprising tar or pitch, after the heat treatment. The plate brick has a compressive strength of 180 MPa or more, and a weight-increasing rate of 1% or less as measured in a hydration test using an autoclave.

Abstract: An average fault ratio is calculated from product characteristics of a product as a target of yield prediction, in order to predict yield accurately in the course of manufacturing the prediction target product. With respect to a reference product, whose wiring pattern is different from the prediction target product but manufactured by the same manufacturing process, a monthly electric fault density is calculated from actually measured data. Respective average fault ratios are obtained from product characteristics of the prediction target product and the reference product. A monthly electric fault density of the prediction target product is obtained by multiplying the monthly electric fault density of the reference product by the ratio of the average fault ratios. The yield is calculated by using the monthly electric fault density of the month in which a yield prediction target lot of the prediction target product was processed.

Abstract: Disclosed is a grid interconnection device that converts electric power from a power supply device into predetermined alternating-current power, and interconnects the power supply device to a power distribution system. The grid interconnection device includes a detector that detects islanding of the power supply device, and a receiver that receives power failure information including local area information indicative of an area in which a power failure occurs, through a predetermined transmission path. The detector enhances detection sensitivity for the islanding when the received power failure information includes the local area information indicative of a different area from the area to which the power distribution system belongs.
