  • Publication number: 20110169748
    Abstract: An interactive input system comprises a display surface and processing structure communicating with the display surface. The processing structure presents on the display surface at least one graphic object, the graphic object having properties and a respective solution state comprising a value of at least one property. The processing structure in response to gesture input manipulates the value of the at least one property, and provides an indication as to whether the graphic object is in its solution state in response to the application of a predetermined amount of pressure against the display surface in association with the graphic object. A method and computer readable medium are also provided.

  • Patent number: 7858155
    Abstract: It is intended to provide a plasma processing method and apparatus capable of increasing the uniformity of amorphyzation processing. A prescribed gas is introduced into a vacuum container 1 from a gas supply apparatus 2 through a gas inlet 11 while being exhausted by a turbomolecular pump 3 as an exhaust apparatus through an exhaust hole 12. The pressure in the vacuum container 1 is kept at a prescribed value by a pressure regulating valve 4. High-frequency electric power of 13.56 MHz is supplied from a high-frequency power source 5 to a coil 8 disposed close to a dielectric window 7 which is opposed to a sample electrode 6, whereby induction-coupled plasma is generated in the vacuum container 1. A high-frequency power source 10 for supplying high-frequency electric power to the sample electrode 6 is provided and functions as a voltage source for controlling the potential of the sample electrode 6.

  • Publication number: 20100204236
    Abstract: Certain novel substituted imidazoles are ligands of the human bombesin receptor and, in particular, are selective ligands of the human bombesin receptor subtype-3 (BRS-3). They are therefore useful for the treatment, control, or prevention of diseases and disorders responsive to the modulation of BRS-3, such as obesity, and diabetes.

  • Patent number: 7759254
    Abstract: A method of forming an impurity-introduced layer is disclosed. The method includes at least a step of forming a resist pattern on a principal face of a solid substrate such as a silicon substrate (S27); a step of introducing impurity into the solid substrate through plasma-doping in ion mode (S23), a step of removing a resist (S28), a step of cleaning metal contamination and particles attached to a surface of the solid substrate (S25a); a step of anneal (S26). The step of removing a resist (S28) irradiates the resist with oxygen-plasma or brings mixed solution of sulfuric acid and hydrogen peroxide water, or mixed solution of NH4OH, H2O2 and H2O into contact with the resist. The step of cleaning (S25a) brings mixed solution of sulfuric acid and hydrogen peroxide water, or mixed solution of NH4OH, H2O2 and H2O into contact with the principal face of the solid substrate.

  • Publication number: 20100148323
    Abstract: A subject of the present invention is to realize an impurity doping not to bring about a rise of a substrate temperature. Another subject of the present invention is to measure optically physical properties of a lattice defect generated by the impurity doping step to control such that subsequent steps are optimized. An impurity doping method, includes a step of doping an impurity into a surface of a solid state base body, a step of measuring an optical characteristic of an area into which the impurity is doped, a step of selecting annealing conditions based on a measurement result to meet the optical characteristic of the area into which the impurity is doped, and a step of annealing the area into which the impurity is doped, based on the selected annealing conditions.

  • Patent number: 7626184
    Abstract: It is an object to prevent functions expected originally from being unexhibited when impurities to be introduced into a solid sample are mixed with each other, and to implement plasma doping with high precision. In order to distinguish impurities which may be mixed from impurities which should not be mixed, first of all, an impurity introducing mechanism of a core is first distinguished. In order to avoid a mixture of the impurities in very small amounts, a mechanism for delivering a semiconductor substrate to be treated and a mechanism for removing a resin material to be formed on the semiconductor substrate are used exclusively.
