| 20120133671 | Method and System for Processing Mass Analysis Data - In an imaging mass analysis, image information of a sample allows users to grasp specific information about the sample, such as distribution of a portion with a particular function or effect. The mass spectrum intensity data are normalized for each pixel so that the sum of the intensities over the entire mass-to-charge ratio (m/z) is one. Entropy is calculated by totaling the product of the intensity normalizing at each m/z and the logarithm of that intensity over the entire m/z range. After the entropy is calculated for each pixel, the pixels are colored according to their entropy values to display a two-dimensional color image of entropy distribution. The entropy of a cancerous portion is relatively small because of a high content of a specific kind of substance and the simplified composition of the substances. Thus, the cancerous part and the normal part of the entropy image can be distinguished. | 05-31-2012 |

| 20120119083 | Ion Trap Device - Ions supplied in the form of a pulse are introduced into an ion trap through an ion entering orifice while a rectangular voltage of a frequency higher than the frequency at which the best trap is accomplished is applied to a ring electrode from a trap voltage generating unit. With this, since a well of a pseudo ion potential is formed in a radial direction in the ion trap, the spread of ions of low m/z values introduced previously is suppressed. A part of ions is introduced into the ion trap, and thereafter the frequency of the rectangular voltage applied to the ring electrode is lowered stepwise to the frequency at which the best trap is accomplished. As a result, the ions of the low m/z values introduced previously can be efficiently trapped, and introduction of ions of high m/z values reaching the ion trap later is not hindered. Consequently, ions of a wide range of m/z values can be trapped in the ion trap with high efficiency | 05-17-2012 |

| 20120112255 | Solid-State Image Sensor - A floating diffusion region is formed at an edge of a light-receiving surface of an embedded photodiode, with a transfer gate electrode located therebetween. A first region, with radially extending portions centered on the FD region, and a second region, located to the outside of the first region, are created in the substantially sector-shaped light-receiving surface. A dopant whose conductivity type is the same as the signal charges to be collected in the first region are introduced, whereby an electric field for moving the signal charges from the radially extending sections towards the center is created due to a three-dimensional field effect. As a result, the charge-transfer time is reduced. Additionally, since a circuit element in the subsequent stage can be placed adjacent to the floating diffusion region, the parasitic capacitance of the floating diffusion region can be reduced and a highly sensitive element can be obtained. | 05-10-2012 |
| 20120112060 | Multi-Turn Time-of-Flight Mass Spectrometer - A multi-turn time-of-flight mass spectrometer creates, an accurate mass spectrum of a wide mass range, with the smallest number of measurements. Deflecting electrodes are provided on an ejection path through which ions deviating from a loop orbit fly to a detector having a two-dimensional array elements. A varying voltage applied to the deflecting electrodes creates an electric field. When two ions having different mass-to-charge ratios simultaneously arrive at the detector, these ions are affected with differing strengths since they pass through the deflecting electric field at different times. This results in arrival for the ions on a detection surface. The time an ion passing through the deflecting electric field can be calculated from the displacement of the arrival position of that ion. Then the flight speed of the ion is obtained and its number of turns is roughly deduced to arrive at its mass-to-charge ratio. | 05-10-2012 |

Moreover, a vertical displacement control unit feedback-controls a vertical position scan unit so as to obtain a constant distance between the probe needle and the sample according to a frequency shift by a frequency detection unit.

| 20110062325 | Quadropole Mass Spectrometer - If a scanning rate of a mass scanning is set to be high, the amount of change in an applied voltage between a time of an incidence of a certain ion into a quadrupole mass filter and a time of an emission of the ion therefrom increases. This leads to a change in the condition of a passage of ions, causing the amount of ions to decrease and thereby deteriorating detection sensitivity. In order to avoid this problem, according to the present invention, the values of direct current voltage U and an amplitude V of radio-frequency voltage, both voltages being applied to rod electrodes during a mass scanning, are respectively determined so that a voltage ratio U/V of the voltage U to the amplitude V becomes smaller as the scanning rate becomes higher. Accordingly, in a stability diagram based on the Mathieu equation, the inclination of line L indicating the change in the applied voltage during the mass scanning becomes gradual and the amount of ions passing through the quadrupole mass filter increases particularly when the mass is high. | 03-17-2011 |

| 20110036976 | Atmospheric Pressure Ionization Mass Spectrometer - The present invention aims at suppressing noises when a mass analysis is performed by introducing a sample solution into an atmospheric pressure ion source by a pressurized liquid feeding method. As a dilution solvent of the sample solution contained in a sample container, a mixed liquid is used in which the mixture ratio of an organic solvent such as methanol is decreased to 20% and the ratio of water is 80%. Since nitrogen, which is a gas for the pressurization, is soluble in an organic solvent, decreasing the ratio of the organic solvent lowers the saturated dissolution amount and suppresses unstable emergence of the gas in the process of the mass analysis. Consequently, even after the elapse of a considerable length of time from the start of liquid feeding, spike-like noises do not appear in the ion intensity, which stabilizes the ion intensity. | 02-17-2011 |

Since a radius of curvature is 1 μm or more, a focal length of an electron gun can be longer than in a conventional practice wherein a radius of curvature is in the range of from 0.5 μm to not more than 0.6 μm.

Since the angular current intensity (the beam current per unit solid angle) is proportional to square of the electron gun focal length, the former can be improved by an order of magnitude within a practicable increase in the emitter radius. A higher angular current intensity means a larger beam current available from the electron gun and the invention enables the Schottky emitters to be used in applications which require relatively high beam current of microampere regime such as microfocus X-ray tube, electron probe micro-analyzer, and electron beam lithography system. | 05-27-2010 |
