An aspect of the present invention relates to a magnetic tape comprising a magnetic layer containing a ferromagnetic powder and a binder on a nonmagnetic support, whereinthe ferromagnetic powder is a hexagonal ferrite powder,squareness in a vertical direction without demagnetizing field correction of the magnetic layer ranges from 0.6 to 1.0, andthe magnetic layer further comprises a compound in which a substituent selected from the group consisting of a carboxyl group and a hydroxyl group is directly substituted into a ring structure comprising a double bond and having a ClogP falling within a range of 2.3 to 5.5.

A radiation therapy System comprises a magnetic resonance imaging (MRI) apparatus and a linear accelerator capable of generating a beam of radiation. The linear accelerator is immersed in and oriented with respect to the MRI magnetic field to expose the linear accelerator to magnetic force that directs particles therein along a central axis thereof.

A fine-pitch terminal and connector reduces the size of a connector in a direction in which a large number of terminals are arranged in parallel. A terminal is applied to a connector, to which a cable having a conductor covered with an insulator is attached, the terminal being connected to the conductor of the cable by soldering. The terminal has a soldering region which is provided in a part of the terminal and to which the conductor of the cable is soldered, and the soldering region has a depression for receiving a fillet.

A miniature mass spectrometer is disclosed comprising an atmospheric pressure ionisation source and a first vacuum chamber having an atmospheric pressure sampling orifice or capillary, a second vacuum chamber located downstream of the first vacuum chamber and a third vacuum chamber located downstream of the second vacuum chamber. An ion detector is located in the third vacuum chamber. A first RF ion guide is located within the first vacuum chamber and a second RF ion guide is located within the second vacuum chamber. The ion path length from the atmospheric pressure sampling orifice or capillary to an ion detecting surface of the ion detector is ≦400 mm. The mass spectrometer further comprises a tandem quadrupole mass analyser, a 3D ion trap mass analyser, a 2D or linear ion trap mass analyser, a Time of Flight mass analyser, a quadrupole-Time of Flight mass analyser or an electrostatic mass analyser arranged in the third vacuum chamber. The product of the pressure P1 in the vicinity of the first RF ion guide and the length L1 of the first RF ion guide is in the range 10-100 mbar-cm and the product of the pressure P2 in the vicinity of the second RF ion guide and the length L2 of the second RF ion guide is in the range 0.05-0.3 mbar-cm.
