  • Publication number: 20070092897
    Abstract: A method for labeling an object, which is effective when multiple types of labels are given as necessary even to a very small object such as a fine particulate substrate for use in fixation of biological substances such as probe molecules or nucleic acid primers that are used for a bioassay is provided. Further, an object given the labels is provided. Multiple types of labels can be given as necessary even to very small objects by using materials for labeling prepared in accordance with the composition condition of contained atoms corresponding to at least binary system n-digit numerical value information using a plurality of types (n types) of atoms selected beforehand as part of materials constituting the object, and presence/absence of the selected individual atoms contained or the level of the contents thereof. Further, the bioassay can be performed by the object labeled by the labeling method.

  • Patent number: 7188031
    Abstract: A measurement method is provided, which enables to obtain a two-dimensional image with better quantitative-ability by suppressing the influence of the charge-up, when the two-dimensional secondary ion image is obtained for a biological material fixed on a substrate having a high resistivity by utilizing a TOF-SIMS method in a certain wide area. A two-dimensional image having considerably high positioning resolution-ability can be obtained by the procedure in which the pulsed primary ion beam is irradiated at a spot, and the pulse-wise spot-applications of the primary ion beam and the simultaneous detection of the secondary ion generated from the irradiated primary ion beam proceed along with a discontinuous scanning pattern, and eventually the results of these secondary ion measurements are reconstructed into a two-dimensional image in line with the aforementioned discontinuous scanning pattern.

  • Patent number: 7036576
    Abstract: An air conditioning unit and an air blowing unit are connected via an intermediate duct. The air blowing unit is provided on the left side of the air conditioning unit in the forward direction of a car. The air conditioning unit includes an air mix damper and a discharge direction switching damper for switching the discharge direction of conditioned air, each driven by a corresponding actuator via a link mechanism associated therewith. The link mechanism and the actuator are provided on a wall part of the air conditioning unit. From the perspective of the forward direction of a car, the link mechanism and actuator are mounted on a left wall part of the casing of the air conditioning unit. On the other hand, the air blowing unit is provided with an actuator for driving an indoor air/outside air switching damper, and the actuator is mounted to a side of a casing of the air blowing unit facing the air conditioning unit. Thus, the resulting air conditioner is reduced in size to reduce its installation space.
