A compression molding which is high in both dimensional accuracy and mechanical strength is difficult to manufacture by a powder molding process. Especially, a molding including a soft magnetic material with high soft magnetic properties is difficult to manufacture. A composite metal molding according to the present invention includes metal particles and the carbide of a resin intervening among the particles. It is manufactured by coating metal particles with a resin, molding the prepared molding material under pressure into a predetermined shape, and heating the prepared pressurized preform to calcine the resin and weld mutually the particles. The carbide of the resin has a weight ratio of 0.001 to 2% to the metal particles when the particles have their proportion expressed as 100. The particles have a weld ratio of 10 to 80%. The particles preferably contain a soft magnetic material and the resin is preferably a furan resin.

Composite metal molding and method for manufacturing thereof

To provide a sheet material identifying apparatus for identifying the kind of a sheet material, including an adjusting assembly for dehumidifying or humidifying a predetermined region of the sheet material and adjusting the moisture content of the predetermined region, external force applying means for applying an external force to the predetermined region of the sheet material whose moisture content is adjusted and detecting means for detecting an external force propagated through the sheet while the external force is applied by the external force applying means; wherein an external force is applied to the predetermined region whose moisture content is adjusted through the adjusting assembly by the external force applying means and the kind of a sheet material is identified in accordance with the external force propagated through the sheet detected by the detecting means.

Disclosed is an information detecting device capable of reducing fluctuation in detection accuracy. A recording sheet P transported through a transport path comes into contact with a displacing member, and, in this state, a motor is driven to rotate a cam, and the resilient force of a coil spring causes a pressurizing member to collide with the recording sheet P. The impact force at that time is detected by a detection sensor, and transmitted to a sheet material information obtaining means. Then, on the basis of the detection result, it is possible to detect the type, density, thickness, surface irregularities, etc. of the recording sheet P. At this time, the recording sheet P is in contact with the displacing member, whereby it is possible to reduce fluctuation in detection accuracy due to positional deviation of the recording sheet P.

A sheet material information-detecting apparatus is provided which is capable of detecting the type of a sheet material even if the sheet material is anisotropic. When recording paper sheet P is fed, feed rollersandare moved to narrow the nip of the rollers and front edge of recording paper sheet is pushed thereto to correct the oblique feed. Thereafter, external force is applied to recording paper sheet P by external force applying member. A signal based on the external force is detected by signal detecting means, and sheet material information-acquiring meansidentify the type of the recording paper sheet. Owing to the oblique feed correction, the type of the sheet material can be identified precisely even if the sheet material is anisotropic.
