Title: Permanent magnet rotor
Inventor: TAJIMA FUMIO
IPC: H02K1/27
Filed: 1983-10-26
Abstract: PURPOSE:To enable to mainly magnetize a magnet without any positioning operation by forming a cutout at part of a yoke disposed between the poles of a permanent magnet. CONSTITUTION:Cutouts 13 are formed at an interval on part of the outer periphery of a bore side yoke 7 disposed between the poles of the permanent magnet 8 of a permanent magnet rotor. When a magnetizing operation is performed, currents are flowed through two or three phases of stator windings by a magnetizing unit. In this case, even if the position of the rotor is displaced, salient poles are formed by the presence of the cutouts 13 on the rotor. Accordingly, the centers of the poles of the magnet 8 are affected by the force for moving it to the center of the magnetomotive force of the winding. Thus, the center position of the permanent magnet is moved to the center position of the magnetomotive force of the winding to be magnetized.

Title: Production of toner
Inventor: ITABASHI HITOSHI
IPC: G03G9/087
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To obtain a toner which satisfies blocking resistance, allows low- temperature fixing, makes it possible to obtain sufficiently image densities even at and under low temperature and low humidity and is free of degradation in image quality in spite of endurance by lightly adhering pigment t particles to resin particles and fixing the adhered pigments into the inside of the particles. SOLUTION: The pigment particles are lightly adhered to the resin particles in a first step. Namely, the resin particles and the pigment particles are mixed by a dry process and the pigments are adhered to the resin particle surfaces by mechanical agitation. The adhered pigments are fixed to the inside of the particles in a second step. The particles adhered with the pigments are dispersed into a medium which itself does not dissolve but dissolves a softening agent, into which the softening agent is dissolved. The softening agent is selectively absorbed in the colored particles and simultaneously the pigments on the particle surfaces are fixed in the form oil drops into the particles by lowering the solubility of the softening agent in the medium.  As a result, the toner, which is free from composition of the particles with each other and is free from the lacking of the pigments is produced even if Tg of the resin is low, is produced.

Title: Manufacture of dense concrete surface
Inventor: UCHISAKI IWAO
IPC: B28B3/02
Filed: 1987-08-12
Abstract: PURPOSE:To improve the hardness, strength and abrasion resistance of a dense layer by a method in which after the upper surface of concrete which is placed on a holder plate and has the low ratio of water to cement in such a grade that the fluidity of the concrete is lost, has been pushed and extended by an ultrasonic wave resonant body, it is stood as it is and is cured. CONSTITUTION:The concrete paste 7 having the ratio of water to cement of 15%-23%, is put in a frame 6. The ultrasonic wave resonant body 8 of a roller type rotated by a motor is moved in pressure contact, while it is slid relatively onto the cement paste, and then said paste is hardened tightly by generated ultrasonic wave, whereby a dense cement layer 9 is formed. By additionally applying the reinforcing concrete 10 for said layer 9, a precast concrete plate with an arbitrary area and thickness is obtained. In this case when the ratio of water to cement is less than 15%, the dense layer becomes very thin and cracks occur, and the thickness of the dense layer increases quickly in the range of 15%-23%, and further, when said ratio exceeds 23%, the dense layer is not generated.
