摘要： PROBLEM TO BE SOLVED: To make machining be performed while smoothly operating a tip of a tool without changing an instruction point of a machining program even when there is an instruction of an intermittent attitude change of the tool or when there is an instruction of a discontinuous attitude change amount of the tool. SOLUTION: A rotation-axis filter processing part 5 applies moving average filter to an angle change amount between interpolation points 13 of a rotation angle of a rotation shaft according to a filter time constant previously imparted by a parameter or the like of a machine tool to smooth the angle change amount between the interpolation points 13. A translation-axis timing synchronization part 6 applies the moving average filter to a movement amount between interpolation points 14 of tool-tip positions of a translation axis to synchronize timing of movement of the translation axis with smoothing-processed rotation of the rotation shaft. A coordinate transformation part 7 performs coordinate transformation into a machine position 17 of the translation axis according to a configuration of the machine tool, from each tool-tip position 16 after the timing synchronization between the translation axes and each rotation angle 15 of the rotation axis after being filtered.

摘要： PURPOSE:To control the energy propagation by allowing the direction of a conductor, which is taken in and out between central conductors in a side coupling cavity of a cavity resonator, to coincide with the direction of the electromagnetic field and providing a member, which short-circuits central conductors, in the front end of said conductor as one body. CONSTITUTION:A side coupling cavity 13A is provided for acceleration cavities 9 and 10. The power of the electromagnetic wave supplied from a power supply part to the acceleration cavity 10 is propagated to the side coupling space 13A through a coupling hole 18 and reaches the acceleration cavity 9 through a coupling hole 17. Resonance frequencies of acceleration cavities 9 and 10 and the side coupling cavity 13A are equalized. When a T type conductor 31 is moved to a position indicated by a dotted line, the TEM mode is excited in the cavity 13A, and the resonance frequency at this time is set to be equal to the resonance frequency of acceleration cavities 9 and 10. The electromagnetic wave between the coupling cavity 13A and coupling holes 17 and 18 is greatly disturbed and the phase difference is 180 deg., and the phase difference between acceleration cavities 9 and 10 is 0 deg., and the energy gain is zero between acceleration cavities 9 and 10. Thus, the number and positions of side coupling cavities are selected to easily change the transmission energy.

摘要： PURPOSE:To supress a transmission loss and exothermic of high-frequency waves and, at the same time, to carry out stable high-frequency wave transmission, by providing Cu-plated layer to prescribed sections of 1st and 2nd flanges. CONSTITUTION:High frequency waves entering from a 1st window 1W of the 1st flange 1 enter into a vacuum chamber 6V after passing through a ceramic plate 5 from a pressure chamber 6P and further enter into an accelerator which is not shown in the figure from a 2nd window 2W of the 2nd flange 2. Since Cu-plated layers 7 are provided on the 1st and 2nd flanges 1 and 2, stable high- frequency wave transmission can be carried out when the high-frequency waves are passed through the high frequency windows, since the transmission loss and exothermic of the high-frequency waves can be suppressed by means of the layers 7. Moreover, since when the layers 7 are provided on the 1st and 2nd flanges 1 and 2, the transmission loss and exothermic of the high-frequency waves can be suppressed, the high frequency windows can be constituted inexpensively.

摘要： PURPOSE:To accurately measure a current taking the form of a high-speed pulse. CONSTITUTION:When a pulse-form beam of charged particles passes through a beam duct 5, it produces magnetic flux in a core 9. This magnetic flux causes current through a conductor 2, and the current is taken out from a connector 3 whereby the current passing through the beam duct 5 can be measured without contact. The core 9 is manufactured by winding into a toroidal shape an alloy tape made of fine crystal grains made of an iron or cobalt alloy. The waveform of the highspeed pulse and the current value can be measured at high accuracy and the rate of aged deterioration is reduced.
