Spinel-type ferrimagnetic particles having a composition represented by the formula:(MO)&#xb7;/2(FeO)where M is a divalent metal and n is a molar ratio of Fe to M (n=Fe/M) which is from more than 2.05 to less than 2.5 (2.05&#x3c;n&#x3c;2.5). They contain a superparamagnetic component in an amount of not more than 2% by mass, has an average particle diameter of 5 to 30 nm. The particles are respectively coated on surface with a hydroxide of at least one metal Si, Al, P and Zn in an amount of not more than 10% by mass, calculated as the metal. The spinel-type ferrimagnetic particles can exhibit a high coercive force irrespective of fine particles, and are excellent in dispersibility and chemical stability, as well as the magnetic recording medium for high-density recording can exhibit not only excellent frequency characteristics and high output characteristics, but also an excellent weather resistance and a high reliability.

An injection-molding process including kneading functional particles with a binder resin in a kneader, temporarily storing the kneaded material supplied from the kneader in a reservoir device and feeding the kneaded material stored in the reservoir device to an injection device, the reservoir device including a pair of reservoirs, the kneaded material stored in one reservoir device is fed to the injection device where the kneaded material is then injection-molded, and simultaneously the kneaded material is fed from the kneader to another reservoir device and stored in it. Then, the kneaded material stored in the other reservoir device is fed to the injection device where the kneaded material is then injection-molded, and simultaneously the kneaded material is fed from the kneader to the one reservoir device and stored in it, so that the injection molding process is conducted by alternately repeating the above steps by switching operations. This injection-molding process is capable of producing a molded product of uniform quality by preventing feed pressure of the kneaded material fed to an injection device from being transmitted to the kneader.

Injection molding process using a pair of reservoirs and an injection device

An injection-molding device including an injection machine, a mold unit connected to the injection machine having separable molds defining a cavity for forming a molded product, and chucks next to the mold unit for removing a molded product from the mold. The molded product is initially coolied in the mold cavity then again cooled after removal from the mold unit. Plural chucks are advanced into and retreated from a region defined by the open molds, the chucks being a pair of blocks grasping the surface of the molded product, each block having a circulating path through which a heating medium is passed to cool the grasping surface. The injection-molding apparatus produces articles having high dimensional accuracy, for example, electronic parts such as a magnet roll or the like.
