摘要:
A biosensor is formed by immobilizing metal particles immobilized on a surface of a carrier and immobilizing probe molecules which are modified with fluorescent molecules on the metal particles. A biomolecule is detected at high sensitivity by use of this biosensor and utilizing fluorescence-quenching and fluorescence-enhancement effects attributable to the metal particle. In this way, it is possible to omit amplification of the biomolecule in a specimen and fluorescence-labeling on the biomolecule when detecting the biomolecule with the biosensor. It is also possible to improve quantitative reliability and repeatability of the biosensor.

摘要:
In an autoanalyzer for analyzing samples, such as urine and blood, analytical and measured values are prevented from being affected by carry-over caused by the repeated use of a pipetting nozzle. A molecular layer for inhibiting the adsorption of biological polymers is formed by coating surfaces of the pipetting nozzle with a polyethylene glycol derivative chemisorbed thereto, thereby reducing carry-over caused by the pipetting nozzle.

This invention provides a cell made of polymers for spectra measurement while inhibiting a decrease in a molecular weight of resin caused by discharge treatment and having a stable hydrophilic modified surface. The hydrophilic resin cell is prepared by providing a polymeric resin cell between the two opposing electrodes, applying an electric field to a region between the above opposing electrodes under a nitrogen atmosphere with a pressure close to the atmospheric pressure to generate an electric discharge, and exposing the cell subjected to discharge treatment with a gas including oxygen.

An on-vehicle information processing apparatus for implementing various functions in cooperation with a portable apparatus connected thereto in a cabin of a vehicle is disclosed. The on-vehicle information processing apparatus comprises: a communication device configured to communicate with the portable apparatus; and a screen generating device configured to generate an operation screen for the functions which can be implemented in cooperation with the portable apparatus. The screen generating device is configured to identify the functions which can be implemented in cooperation with the portable apparatus connected thereto via the communication device, based on information of the connected portable apparatus, and generate the operation screen which varies according to the identified available function or functions.
摘要:
A specification plan of an order-made product suitable for a building structure plan is generated promptly.A WWW server 11 and a database server 12 are provided to the equipment designer's side. The database server 12 has a drawing database 9 that registers a CAD symbol for each product. A CAD symbol for each product includes: effective space information, which expresses a space to be secured for installation of the product; product name information expressing a name of the product; structure information expressing structural features (size, shape, etc.); product specification information; option data; etc. On the other hand, WWW server 11 has a symbol generation data interface 3, through which requirements specification data for an order-made product can be received from a WWW client terminal 2, and a CAD symbol of the order-made product can be taken out from the side of the WWW client terminal.
摘要:
A vehicle-mounted communication device and a road-to-vehicle communication device are provided which each allow communication of information using a simple structure by making leakage of information difficult. Information including encryption information is communicated between an on-road apparatus 10 having a memory 28 in which an electronic key A is stored, and a vehicle-mounted apparatus 30 having a storage circuit 48. Encrypted route information and the like are stored as is in the vehicle-mounted apparatus 30. Encryption and decoding are executed at an on-road apparatus side. In reception of charges, encrypted information from an IC card 62 having a memory 70 in which a security mechanism is stored passes through the vehicle-mounted apparatus and is transferred to the on-road apparatus. The encrypted information from the IC card 62 is decoded with the on-road apparatus. Accordingly, the encrypted information is mutually transferred between these apparatuses and the vehicle-mounted apparatus does not require encryption or decoding. As a result, the security of a system can be improved.
