Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To reduce thrust hysteresis by forming at least a housing, out of the housing, a fixed core and a plunger, of a magnetic material whose value obtained by multiplying the ratio of a residual magnetic flux density to a saturation magnetic flux density by the ratio of a coersive force to the strength of a magnetic field that demonstrates the saturation magnetic flux density is a specific value or less. SOLUTION: A linear solenoid S gives freely changeable thrust to a spool valve V provided between a hydraulic source 1 can a hydraulic working part 2. The thrust exhibits a hysteresis characteristic that generates difference between the increasing side and the reducing side. A housing 4 is formed of a material that has 0.15 or less value TH =(Br/Bs)×(Hc/Hs)}, which is obtained by multiplying the ratio of a residual magnetic flux density Br to a saturation magnetic flux density Bs by the ratio of a coercive force Hc to the strength Hs of a magnetic field that demonstrates the saturation magnetic flux density Bs , in the hysteresis curve of the magnetic material that forms the housing 4 of the linear solenoid S. Thus, the thrust hysteresis can be suppressed to 1.6% or below to the maximum value.

Abstract: PURPOSE:To make it possible to sufficiently stir even with a small volume of air, by producing three-phase flows of air bubbles, fermentation liquor in the fermenter and a granular material having a specific gravity to that of the fermentation liquor. CONSTITUTION:Air is fed from the bottom to stir a fermentation liquor 3 by an air lift effect.

A granular material 4, consisting of ceramics, resin, etc., and having a specific gravity almost similar to that of the fermentation liquor 3 to be fermented in the fermenter 1 is mixed in the fermentation liquor 3. Thus, since the granular material 4 and the fermentation liquor 3 are stirred by air bubbled generated by the inflow of the air, the use of an inert gas, e.g. nitrogen gas, etc., for stirring is not required. Thereby, running cost can be reduced and an area for installing a feeding apparatus for the inert gas, etc., can be reduced.
