Abstract:
A sputtering apparatus includes a rotatable rotary member to which a target is attached, connection terminals, and feeding terminals. The connection terminals are arranged on the end portion of the rotary member in a direction along the axis of rotation of the rotary member, and are electrically connected to the target. The feeding terminals supply electric power to the target via the connection terminals. When the rotary member is rotated while the feeding terminals are in contact with the end portion of the rotary member, the electrical connection or insulation state between the feeding terminals and connection terminals is switched.
Abstract:
A vacuum film forming apparatus includes a target chamber in which a target is disposed for performing a vacuum film forming; a first mold at a side of the target chamber; and a second mold that includes a workpiece chamber in which a workpiece is capable of being disposed. The first mold and the second mold are structured such that a film being formed onto the workpiece is capable of being carried out by die matching between the first mold and the second mold, and a shutter device for opening and closing the target chamber is provided to the first mold.

An electrostatic latent image developing toner has an average sphericity of at least 0.94 but no more than 0.98, the particles for which the accumulated equivalent spherical diameter on a number basis is at least 90% and the sphericity is less than 0.92 account for less than 3% of the entire toner, the proportion of particles having a sphericity of at least 0.90 but less than 0.95 is at least 20% but no more than 40% of the entire toner, and a proportion of particles having a sphericity of at least 0.95 but no more than 1.00 is at least 60% but no more than 80% of the entire toner.
Abstract:
In an X-ray generating device of the neutral grounding system, to remove an unbalance voltage generated due to difference in impedance of parallel transformer coils of the high voltage transformer and particularly an unbalance voltage involved with difference in impedance above and below the neutral points generated in a metal X-ray tube, a plurality of currents flowing in opposite directions through primary windings of the parallel transformer coils in the high voltage transformer are passed through by or wound around a common toroidal coil or wound around an outer circumference of the toroidal coil at a predetermined ratio of winding number, and the unbalance voltage occurring to the secondary side is cancelled by changing primary current with magnetic behavior.
Abstract:
A communication terminal that builds a wireless network includes a control-information transceiver that transmits and receives control information indicating number of times of forwarding required for a communication with the communication terminal, with respect to other communication terminals connected to the wireless network; a routing-information creating unit that creates, based on the control information received, routing information indicating an initial forward-destination terminal to which data is firstly transmitted when the communication terminal is a destination, for each of the other communication terminals; and a data transmitting unit that transmits the data based on the routing information.
Abstract:
A switching type power source device used for magnetic field generation coils for an MRI device in which a switching power sources (9˜11) are constituted by a first and a second multi level PWM inverter (12,13) having a same number of potential levels connected in parallel each other with respect to magnetic field generating coils (6˜8) for the MRI device working as a load as well as a switching control circuit (19) for drive controlling the first and the second multi level PWM inverter (12,13) is constituted to drive control the first and the second multi level PWM inverter (12,13) in a manner to shift the switching phases thereof each other, thereby, ripple components in currents output from the first and the second multi level PWM inverter (12,13) are canceled out each other and a current with a further reduced ripple components as a whole can be supplied to the load (6˜8).
