摘要： The invention provides a method for preparing a soft magnetic material which meets demands for low iron loss, high density, high strength and high productivity. The method comprises a surface oxidation step of forming oxide films on the surfaces of a soft magnetic powder, a step of preparing a molding compound of the soft magnetic powder by mixing a soft magnetic powder and a binder with a predetermined blending ratio, a press molding step of press-molding the molding compound of the soft magnetic powder into a predetermined shape, and a sintering step of sintering the press-molded soft magnetic powder to produce a soft magnetic material, wherein a millimeter wave sintering apparatus or a discharge plasma sintering apparatus is used as a heating means in the surface oxidation step or in the sintering step. Thereby, energy of millimeter waves or discharge plasma acts locally on oxidized surface portions having a large electric resistance of the soft magnetic powder, the surfaces of the soft magnetic powder are locally heated at a temperature near the melting point, and oxidation of the surfaces of the soft magnetic powder (formation of an oxide film) and sintering (diffusional joining between oxide films) are promoted.

摘要： An air-supply module including an air cleaner case, a throttle body, a surge tank, manifold pipes and other components is integrated into one single unit. The module is mounted as a whole on an internal combustion engine by simply connecting a flange formed at an eigne side end of the manifold pipes to intake ports of the engine. Bolts sticking out of the intake ports are inserted into mounting holes formed on the flange, and nuts are screwed onto the bolts by a nut runner. The mounting holes on the flange are located between the manifold pipes so that the nut runner can reach the nuts directly from the outside of the module without disassembling any components already assembled into the module. Other components including the air cleaner case are disposed in the module to secure a tool space and not to interfere with the mounting operation.

摘要： The invention provides a method for manufacturing a soft magnetic material, wherein an Fe—Si alloy powder is heated in a weakly oxidizing atmosphere to form a SiO2 oxide film on the surface, and the powder is then press-molded and fired in a weakly oxidizing atmosphere to obtain a sintered product. By performing the surface oxidizing step in a weakly oxidizing atmosphere such as water vapor, Si is selectively oxidized to form a thin oxide film with high electrical resistance. Furthermore, by firing the molded product in a weakly oxidizing atmosphere, the sintering can be performed while the oxide film, in which cracks and the like are generated at the press-molding, is repaired.

摘要： An internal combustion engine has a plurality of cylinders and intake passages leading to the cylinders respectively. A plurality of intake control valves block and unblock the intake passages respectively. Drive devices open and close the intake control valves mutually-independently. A detecting device serves to detect a predetermined condition of the engine under which a speed of the engine is required to vary. A control device performs a control of closing the intake control valves mutually-independently by use of the drive devices after the detecting device detects the predetermined condition of the engine.

摘要： A field-winding type of synchronous machine comprises a stator with an armature winding wound phase by phase, a rotor having a rotor core with a field winding wound, and a circuit enabling an armature current to pass the armature winding, the armature current corresponding to a synchronous current producing a rotation field rotating at an electrical-angle rotation speed agreeing to a rotation speed of the rotor. The synchronous machine further comprises a current suppressor and a current supplier. The current suppressor is connected to the field winging and suppresses, into a unidirectional current, an induced alternating current induced through the field winding in response to the armature current passing the armature winding. The current supplier supplies, phase by phase, to the armature winding a rotor exciting current whose waveform is different from the synchronous current only during a predetermined period of time shorter than one cycle of the synchronous current.
