A position calculation method includes: by using a current position of a mobile object, a link candidate point position, an error variance of positions of a plurality of links included in a region around the current position, and an error variance of azimuths of the plurality of links, calculating, an evaluation value that corresponds to a probability that the mobile object is traveling upon a road corresponding to each link candidate point, for each link including the each link candidate point; and calculating the current position based upon the evaluation value, by taking the mobile object as being positioned at a link candidate point, among a plurality of link candidate points, for which the probability is highest.

Position calculation method and position calculation apparatus

A position estimation device includes: a mathematical expression model processing unit that calculates a position of a mobile object, a condition quantity indicating a moving condition of the mobile object and an error in the condition quantity through filtering processing executed by using a probability model based upon an attitude information and a positioning information of the mobile object having been obtained from sensors and a specific mathematical expression model among a plurality of mathematical expression models expressing behavior of the mobile object; a threshold calculation unit that calculates a threshold candidate value for a threshold value to be used as a criterion when selecting the specific mathematical expression model, by using the error; a threshold value determining unit that determines the threshold value based upon the threshold candidate value; and a mathematical expression model selection unit that selects the specific mathematical expression model based upon the threshold value.

Position estimation device and position estimation method

A vehicle-mounted information processing apparatus such as a car-navigation system detects that a key switch of the vehicle has been set up at a Lock position (i.e., the engine is stopped). After that, the apparatus performs data reproduction of data files in an order from the oldest, then re-recording the reproduced data files with no change added thereto. Here, the above-described data files, which are stored within a magnetic disk device built in the apparatus, have been not updated for a constant time-period. This re-recording prevents a data loss caused by a thermal decay in the case where the magnetic disk device is mounted inside the vehicle that is likely to have existed under a high-temperature environment for a long time-period.

The following invention relates to an apparatus and a method for improving the rate of cell fusion. Cells contained in chambers are prevented from adhering to the surface of the walls of a chamber in which they are contained by the pulse-like changes in fluid pressure, which causes the cells to separate from the surface of the chamber.

Method for improving the rate of cell fusion

In order to make it possible to measure the light absorption coefficient of various sorts of substances contained in a light scattering material with a high precision, the wavelength of light transmitted through the light scattering material is varied and the coefficient of light absorption is calculated, starting from a ratio of variations in the intensity of the transmitted light to variations in the wavelength.

Method and equipment for measuring absorptance of light scattering

A method and an apparatus for the treatment of particles or biological cells are disclosed, wherein the particles or cells are precipitated or ascended depending on the specific gravity of a liquid used, and the particles or cells are handled with the aid of a holding plate. A method and an apparatus for the fusion of particles or cells are also disclosed, wherein an electric voltage is loaded on a position between electrodes in a microchamber to fuse the particles or cells held in the microchamber.

Cell handling method for cell fusion processor

A cell handling apparatus is provided with a device for moving cells which are held in chambers of the apparatus, at predetermined periods, preferably a device for generating pulse-like changes in fluid pressure of the chambers, so as to prevent the same portions of the cells from remaining in contact with the wall surfaces of the chambers over a predetermined period of time.

Cell handling apparatus

Disclosed is a cell manipulating apparatus for conveying cells to a plurality of chambers provided in a chamber plate. The apparatus comprises a taking-up device adapted to take up cells to the respective taking up portions of a carrier plate placed in positions corresponding to those of said chambers in the chamber plate and a moving device adapted to move, relatively with respect to the chamber plate, the taking-up device to a position above the chamber plate. The taking-up portions may be effectively composed of pressure-controlled cavities or SiO.sub.2 films provided in the carrier plate.

Cell manipulating apparatus

A lithography apparatus in which a charged particle ray such as an electron beam or an ion beam is controlled to scan a desired region of a sample and thereby draw a pattern, including a framing pattern memory for storing therein closed framing lines of a pattern to be drawn in the form of dot images, a framing pattern generator for writing the framing lines of the pattern to be drawn into said framing pattern memory in the form of dot images, and a raster scanning circuit for scanning the framing pattern memory having stored therein closed framing lines of the pattern to be drawn and for generating a beam deflection address for drawing the pattern and a beam blanking control signal.
