摘要： A mass analyzer includes: an ion trap device including an ion trapping space surrounded by a plurality of electrodes; a time-of-flight mass analyzer for determining a mass to charge ratio of ions ejected from the ion trapping space; a trapping voltage generator for generating an ion trapping RF voltage to at least one of the plurality of electrodes; an ejecting voltage generator for generating an ejecting voltage to at least one of the plurality of electrodes to form an ion ejection electric field for ejecting ions trapped in the ion trapping space; and a controller for stopping the ion trapping RF voltage at a timing when ions are trapped in the ion trapping space and the ion trapping RF voltage is at a predetermined phase, and for applying the ion ejecting voltage a predetermined period after the ion trapping RF voltage is stopped. Here the predetermined phase and the predetermined period are predetermined so that, when the ion trapping RF voltage is stopped at the predetermined phase and the predetermined period passes, the voltage of said at least one of the electrodes to which the ion trapping voltage is generated becomes almost a certain fixed value irrespective of the amplitude of the ion trapping RF voltage when it is stopped. Thus, by stopping the ion trapping RF voltage and applying the ion ejecting voltage at such a timing, the initial kinetic energy of the ejected ions does not vary with the amplitude of the ion trapping voltage before it is stopped, and a precise determination of the mass to charge ratio of the ions becomes possible.

摘要： The present invention provides a time of flight mass spectrometer having an ion optics forming a multi-turn track, which is capable of time-focusing the ions while allowing the multi-turn track to be configured in an unlimited and highly variable manner. In a specific form of the invention, a reflector 9 is provided on the flight path between the position where the ions leave the loop orbit P and the ion detector 10 located outside the loop orbit P, and the condition of the electric field generated by the reflector 9 is appropriately determined. Thus, even if the ions cannot be well time-focused by the ion optics 2 creating the sector-shaped electric fields 4 and 7, it is possible to compensate the time-focusing performance with the reflector 9 to achieve a good performance of time-focusing of the ion throughout the overall system wherein the ions leave the ion source 1 and finally reach the ion detector 10. Thereby, the ions can reach the ion detector 10 at approximately the same time even if the ions having the same mass number have different levels of energy at the moment they leave the ion source 1.

摘要： A permanent-magnet rotating machine includes a rotor having a rotor core carrying on a curved outer surface multiple permanent magnets arranged in two rows along an axial direction. The permanent magnets in one row are skewed from those in the other row in a circumferential direction by a row-to-row skew angle (electrical angle) θe. A stator having a tubular stator core in which the rotor disposed includes stator coils for producing a rotating magnetic field for rotating the rotor. A lower limit of the row-to-row skew angle θe larger than 30 degrees (electrical angle). A ratio of cogging torque occurring in the absence of skew to cogging torque occurring when the permanent magnets are skewed, at a row-to-row skew angle of 30 degrees is calculated based on the cogging torque ratio, the row-to-row skew angle θe, and B-H curve properties of the stator core. An upper limit of the row-to-row skew angle θe is not larger than the maximum value at which the cogging torque ratio does not exceed the calculated cogging torque ratio at 30 degrees.

摘要： In the mass spectrometer of the present invention, first the length of flight time of a known ion is measured at every turn of the loop orbit. Ideally, the length of flight time at every turn is equal to one calculated based on the speed of the ion and the path length of the loop orbit, but an actual length of flight time deviates from it in a reproducible fashion. Thus, in the present invention, the deviation information is stored in the correction memory at every turn. In measuring an unknown ion, the unknown ion is made to fly the loop orbit a predetermined number of times. Then the flight time of the unknown ion that has flown the loop orbit a predetermined number of turns is measured, and the deviations of the flight time at the turns are corrected using the correction data stored in the correction memory. The mass to charge ratio of the unknown ion is calculated based on the corrected flight time. Thus the deviation of the actual flight time from the theoretical or ideal one is canceled, and the calculated mass to charge ratio becomes more precise.

摘要： A time of flight type mass spectrometer (TOF-MS) of the present invention includes: a flight space containing a loop orbit on which ions fly once or more than once; a flight controller for making ions of a same mass to charge ratio fly the loop orbit at several values of number of turns; a flight time measurer for measuring a length of flight time of the ions; and a processor for determining the mass to charge ratio of the ions based on a relationship between the value of number of turns and the length of flight time of the ions. The speed of ions flying a loop orbit depends on their mass to charge ratios. For ions of the same mass to charge ratio, the difference between the lengths of flight time of the ions flying the loop orbit N turns and of the ions flying the loop orbit N+1 turns depends on the speed of the ions, so that the difference depends on the mass to charge ratio of the ions. The difference in the length of flight time is unrelated to the variation in the starting time (jitter), variation in the detection timing (jitter), etc, so that the value of the mass to charge ratio can be precisely determined free from errors caused by such disturbing factors.

摘要： To provide a sensor mounting structure which enables mounting an automotive sensor directly to the wall section of a part to be detected, without using screws, and also mounting a pressure detector directly to a pressure air passage without using a pressure inlet pipe. The non-circular sensor mounting hole is provided for inserting a part of the sensor housing into the wall section of the part to be detected. In the sensor housing the first locking portion (pawl) and the second locking portion (flange) are integrally formed by molding. The housing 1 is allowed to be inserted into the mounting hole under the condition that the pawl is directed to a specific orientation, and, after insertion, is turned through a specific angle. Therefore the pawl is engaged on the inside surface of the wall section. The flange is engaged on the outside surface of the wall section. The pawl and the flange are designed to hold the wall section of the part to be detected, thereby mounting the sensor. The projection of the hook is engaged with the recess provided in the sensor housing 1, thus locking the sensor from turning.

摘要： In a TOF-MS according to the present invention, ions fly a round orbit or a reciprocal path once or more than once to be separated by their mass to charge ratios before they are detected by a detector, The detector is movable at least in two positions, where the effective distances from the exit of the round orbit or the reciprocal path to the detector are different. The length of time of flight of ions in each position of detector is measured, and the mass to charge ratio of an ion is calculated based on the difference of the lengths of time of flight in at least two positions. Similarly, the ion source may be movable at least in two positions, and a similar method can be used to calculate or estimate the mass to charge ratio of ions.
