摘要： The transverse tooth profile of a screw rotor which meshes with a companion screw rotor is defined by a tooth root circular arc, an outer circumferential circular arc, and two curves interconnecting the tooth root circular arc and the outer circumferential circular arc. One of the curves is defined by a trochoid curve generated by a point on an outer circumferential surface of the companion screw rotor. Alternatively, the curve may comprise two curve segments, and one of the two curve segments comprising a tooth tip arc which is defined as an arc having a radius of curvature equal to or smaller than the difference between a radius of curvature of the outer circumferential circular arc and a radius of a pitch circle of the tooth profile, and the other of the two curve segments comprising a curve connected to the tooth root circular arc and determined by a curve generated by the tooth tip arc of the companion screw rotor. The other curve is defined by determining a curve which defines an imaginary rack and thereafter producing a tooth profile curve generated by the imaginary rack.

摘要： In a gradient magnetic field coil device including: a plurality of main coils generating in an imaging region of a magnetic field resonance imaging device a magnetic field distribution in which an intensity linearly inclines; and a plurality of shield coils, arranged on an opposite side of the imaging region across the main coils, suppressing residual magnetic field generated by the main coils on the opposite side. The plurality of main coils and the plurality of shield coils are connected in series. The device further includes a plurality of current adjusting devices, connected to the shield coils in parallel, independently adjusting currents flowing through the shield coils, respectively, to enhance symmetry of the residual magnetic field. The gradient magnetic field coil device is provided which can suppress generation of eddy current magnetic field even if there is a relative position deviation between the main coils and shield coils.

摘要： A charging apparatus includes a latent image bearing member having a charge generating layer for generating an electric charge by receiving light energy; a light source for emitting light energy for generating the electric charge in the charge generating layer; an electrode; a bias voltage applying portion for applying a bias voltage to the electrode; and an elastic member, which is insulative and transparent, for contacting the electrode to a surface of the latent image bearing member. The electric charge is generated in the charge generating layer by reception of the light energy emitted from the light source, and the surface of the latent image bearing member is electrically charged by applying the bias voltage from the bias voltage applying portion to the electrode. The electrode is provided on the elastic member and is contacted to the surface of the latent image bearing member in a contact area and does not extend to an outside of the contact area.
