摘要:
An immunochromatographic test piece measuring a concentration of a measurement object included in a solution includes a carrier causing the solution that includes the measurement object to flow from an upstream to a downstream of the carrier, and a plurality of color regions arranged at the carrier in series in a flow direction in which the solution flows through the carrier and spaced away from one another in the flow direction. The plurality of color regions each includes a capture reagent and is colored while capturing the measurement object included in the solution by the capture reagent. The plurality of color regions is formed at respective portions of the carrier, the respective portions having same dimensions and including same concentrations of the capture reagent per unit area.

The object of the present invention is to provide a light weight wood cement board having high strength and sufficient toughness. To attain the object, the present invention provides a wood cement board made of a cured raw material mixture of cementitious inorganic powder (C), a material containing silica (S), bundled wood fiber, and mica, wherein the weight ratio of said cementitious inorganic powder and said material containing silica is set to be in the range of between 40:60 and 50:50. The bundled wood fiber has a bulky shape, and gives good toughness to said wood cement board, with the mica improving its dimensional stability. In a case where the C/S is set to be in the range of 40:60 and 50:50, the curing of said board proceeds smoothly, leaving little unreacted material remaining in the board.

In order to ensure the security by access control, or the like, using a limited input/output interface of a household electric appliance without complicated setting manipulations, a refrigerator includes a filter section which permits only establishing a communication with a relay server having a specific IP address. The relay server includes a relay control section for relaying a communication between the refrigerator and a cellular mobile phone or a personal computer, a connectable device database in which a partner device whose communication is permitted by the relay control section to be relayed is registered in conjunction with the refrigerator, and a data conversion section for performing data conversion at the time of the relay according to a difference in the input/output interface between the refrigerator and the personal computer, or the like. The refrigerator and the personal computer, or the like, can establish a communication through the relay server.

A system efficiently determines and stores in memory the logical bit positions of bits in which bit errors have occurred in digital recording devices, etc. The system measures bit errors by comparing a test bit string with a correct bit string, and includes a bit string memory that stores the correct bit string, a word comparator for comparing corresponding words from the test bit string and the correct bit string, an error word content memory that stores the contents of the words containing errors, and an error word position information memory that shows the positions in the correct bit string which correspond to error words in the test bit string that contain the errors. Bit error information in a desired visual format is obtained by performing calculation processing on these memory values.

A preparation method of labeled DNA and use thereof are disclosed. More specifically, the invention relates to a preparation method of labeled DNA by preparation of a complex triple-stranded DNA through an deoxyoligonucleotide complementary to the deoxyoligonucleotide sequence of the 3′ terminal sequence of a certain double-stranded DNA followed by replacement of the 3′ terminal region of the plus strand of said double-stranded DNA with at least one labeled dNTP, and also to said immobilization method of a DNA obtained from the preparation method of the labeled (or modified) DNAs onto a solid support. These subject matters are mainly useful for preparation of labeled DNA molecules.

In a vehicle diagnosis information communication system, electric power is supplied from a battery to a vehicle control computer mounted on the vehicle during a period of vehicle operation, while the electric power is supplied to a radio communication unit mounted on the vehicle irrespective of the vehicle operation. The computer transmits a vehicle information such as engine diagnosis result to the radio communication unit through a communication line. The radio communication unit communicates the received vehicle information to an external site of communication in response to a request of the information form the external site of communication irrespective of the supply of the electric power to the computer. Preferably, the supply of the electric power from the battery to the computer is maintained for a predetermined period after the vehicle operation.
摘要:
A system measures the positions of bit errors in digital recording devices and displays the physical locations of the bit errors and their distribution in such a manner that they can be grasped visually and intuitively. The system compares a data stream to be measured with a correct data stream and measures the bit errors. The apparatus includes a data stream memory which holds the correct data stream, a comparator, a counter which totals the number of bit errors, a measured bit number counter which totals the measured data stream and determines the boundaries of the logical recording blocks of the recording medium, an error number memory which holds the number of errors in each logical recording block, and an error address memory. The physical locations of bit errors are calculated on the basis of the measured and recorded bit error information for each logical block, and the bit error information is displayed on the physical form of the recording medium.
