A magnetic core material made of a Fe-Co base alloy for use at high frequencies, and has excellent high-frequency alternating magnetic properties. The core material composition is Co: 45-53% by weight, C: 0.3-3% by weight, one or both of Mn and Si: 0.1-2% by weight, at least one of Mg, Ca, and Ce: 0.1-0.2% by weight, and the remainder Fe and unavoidable impurities. The structure of the alloy comprises a ferrite matrix containing graphite in an amount of from 1-20% by volume dispersed therein. The material is applied, for example, in a dot impact printer and to a pulse motor.

In a bending magnet, a core which is substantially sectoral or semi-circular in horizontally sectional configuration and in which opposed magnetic poles are formed and a vacuum chamber for storage of a charged particle beam is disposed in a gap between the opposed magnetic poles, and a pair of upper and lower exciting coils for generating a bending magnetic field in the gap between the magnetic poles of core, the reluctance against the magnetic flux passing through a portion of the core adjacent to the inner circumference of the orbit of the charged particle beam and a portion of the core adjacent to the outer circumference of the charged particle beam orbit is equally uniformed over the overall length of the orbit of the charged particle beam. With this construction, the magnetic flux density becomes uniform in the gap between magnetic poles where the magnetic flux passing through the inner and outer circumference side portions is concentrated and the magnetic flux distribution is uniformed in the orbital direction in the gap, thereby eliminating adverse influence upon the charged particle beam, and the bending magnet can be very effective for use in a synchrotron or a storage ring.

A rotor for a rotary electrical machine having a superconductive field winding, wherein thermal resistance means is arranged at contact parts between a damper, which is so disposed as to cover the superconductive field winding, and a damper support which supports the damper from the inner side thereof. A plurality of protuberances are formed on either said damper support or said damper for restricting heat flow between said damper and said damper support. It is possible to cause a cooling medium to flow through interstices which are defined at the contact parts between the damper and the damper support.

After a preheating operation is performed to raise an inner temperature of a heating chamber to a target preheating temperature (first specified temperature) by a first steam superheater of a steam temperature-raising device, a cooking operation is performed to raise, by the first steam superheater of the temperature-raising device, a temperature of steam obtained by heating of water in a steam generator by heaters 42A, 42B of the steam generator and then supply the steam to the heating chamber. In this process, when inner temperature of the heating chamber detected by an inner temperature sensor 81 during the preheating operation has come to or beyond a steam generation start temperature (second specified temperature) which is lower than a target preheating temperature, a control unit 80 decides that a steam generation start condition has been satisfied, and heats water in the steam generator by the heaters of the steam generator.

An inkjet head is disclosed, including a nozzle plate, a passage substrate, and a diaphragm. The nozzle plate forms multiple nozzles for discharging ink. A passage substrate joints to the nozzle plate. On the passage substrate, an individual liquid chamber leading to a nozzle, and a liquid supply chamber connected to the individual liquid chamber through an individual passage are formed for each of the multiple nozzles. The diaphragm forms a piezoelectric element which is laminated on a side opposite to the nozzle plate of the passage substrate and includes a lower electrode, a piezoelectric body, and an upper electrode. The liquid supply chamber formed for each of the multiple nozzles is compartmented by a bulkhead from an other liquid supply chamber, and each of the liquid supply chamber and the other liquid supply chamber include multiple ink supply ports.
