Title: Magnetic coagulation apparatus
Inventor: HAYATA FUMITAKA
IPC: B03C1/025
Filed: 1978-08-07
Abstract: PURPOSE: To raise the efficiency of coagulation by arranging a coagulating grid of a material of a high magnetic permeability in a direction intersecting the direction of magnetic force line in flow path.  
     CONSTITUTION: Three grids 3 made of a material of a high magnetic permeability are arranged in a row at the right angle to the flow direction A of medium in such a way that they intersect the flow direction A of medium and the direction B of magnetic force line at nearly central part between the poles of the magnet 2. Thus, ferro-magnetic substances present in medium are caused to coagulate rapidly while passing through the magnetic coagulation apparatus. The coagulated particles are exfoliated from the coagulating grid 3 by the flowing force of medium when the adherence of the particles reaches a certain amount or more and then transported in the medium. On the other hand, particles coagulated in the medium between adjacent coagualting grids are transported by the flowing force of medium. Thus, the efficiency of coagulation can be greatly enhanced.

Title: Anisotropic bonded magnet
Inventor: KITAZAWA ATSUNORI
IPC: B22F1/00
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To raise the filling rate of an anisotropic bonded magnet and moreover, to realize the enhancement of the orientational property of the magnet by a method wherein specified wt.% of magnet powder, which satisfies the specified relation between the sizes of a mean crystal grain diameter and a particle diameter, exists and specified wt.% of magnet powder, which satisfies the specified relation between the sizes of a mean crystal grain diameter and a particle diameter, exists. SOLUTION: Leting the mean grain diameter of magnet power be denoted by D and the particle diameter of the magnet powder be denoted by d, 50 wt.% or higher to 80 wt.% or lower of magnet powder, which satisfies the relation of 0.5 D<=d<=1.5 D, exists and 5 wt.% or higher to 20 wt.% or lower of magnet powder, which satisfies the relation of 0.01 D<=d<=0.1 D, exists. In a powder particle diameter which is 1.5 times wider than the mean crystal grain diameter, the orientation of the powder can not be fully performed. Moreover, in a powder particle diameter of 1.2 D or narrower, the powder particle diameter is roughly equal with the mean grain diameter and the direction of easy magnetization of an anisotropic bonded magnet is uniquely determined.  When one powder is divided into two, the packing density of the magnet, which was 100% in packing density before the division, is reduced after the division because a gap is surely generated between the two powders. Accordingly, the lower limit of the powder particle diameter is also limited and a powder particle diameter of 0.5 D or wider is batter.

Abstract: PURPOSE: To enable an electromagnetic driving source to be used as the load of battery check by energizing the coil of the electromagnetic driving source in a reverse direction to such an energizing direction that electromagnetic force for driving a light shielding member in order to execute an exposure action is generated, which is set as an energizing direction for the coil. CONSTITUTION: The yoke 24 and the permanent magnet 25 of the electromagnetic driving source are magnetized in the up-and-down direction. The movable coil 26 is pivotally supported so that it can be turned around a shaft P. By making a current flow to the coil 26, the electromagnetic force is generated and rotational force is generated. That means, the so-called meter type electromagnetic driving source is formed. In this way, the direction of the current flowing to the coil is reversed by detecting the ON-OFF of a contact point so as to be reciprocated. By energizing the coil of the electromagnetic driving source in the reverse direction to such an energizing direction that the electromagnetic force for driving the light shielding member in order to execute the exposure action is generated, which is set as the energizing direction for the coil, the battery check is executed.  Thus, the battery check can be realized without using a lock member and the like.
