Patent JP-S61195323-A (JP)
Title: Torque sensor utilizing magnetostriction
Inventor: YAMADA MASAYOSHI
IPC: G01L3/10
Filed: 1985-02-25
Abstract: PURPOSE:To detect an instantaneous torque and a mean value of the torque for stationary, normal and reverse operations under non-contact state by directly imparting magnetic anisotropy to the surface of a torque transmitting shaft and constituting a torque sensor. CONSTITUTION:On the surface of the torque transmitting shaft 1 are formed parts 4, 5 of different stress-strain characteristics or strain magnetic characteristics from those of the matrix of the shaft in spiral pattern to afford magnetic anisotropy. Since these parts of magnetic anisotropy 2, 3 are formed in mutually opposite spiral patterns, magnetic anisotropy becomes symmetrical relative to the plane perpendicular to the torque transmitting shaft 1. The result is the different values of permeability of the parts 2, 3 on the surface of the transmitting shaft 1. When the current is supplied from an AC exciting circuit 10 to exciting winding 7 for exciting the parts 2, 3 on the surface of the transmitting shaft 1, the electrical voltage corresponding to the difference in permeability is excited in differentially coupled detection windings 8, 9. By synchronous detection of the excited voltage by a synchronous rectification circuit 11, the torque as well as its direction can be detected since the phase of the excited voltage is correlated with the torque direction.

Title: Crystallizer
Inventor: UE HIDEKAZU
IPC: B01J19/18
Filed: 1993-02-01
Abstract: PURPOSE:To produce crystalline particles whose diameter is made uniform by installing an annular pipe having a lot of liquid jetting ports in the lower end of an outer pipe of a draft tube and circumferentially and uniformly feed a dissolved liquid to a crystallizer through the annular pipe. CONSTITUTION:A liquid return pipe 23 is connected to an annular pipe 18 integrally installed in the lower end of an outer pipe 9 of a draft tube 10. A heated dissolved liquid 1 in an outer circulating device 17 is uniformly and circumferentially fed into a crystallizer 2 from a lot of liquid jetting ports 17 formed in the annular pipe 18. Therefore the dissolved liquid 1 uniformly comes into contact with crystalline particles which are circulated up and down and agitated in the crystallizer 2 to uniformly grow them. And a feed liquid pipe 24 is connected to the liquid return pipe 23 and the feed liquid 4 is fed, mixed in the dissolved liquid 1 returned to the crystallizer 2. Consequently the feed liquid 4 is uniformly distributed in the crystallizer 2 to prevent the unevenness of the concentration and temperature of the dissolved liquid 1, allowing crystalline particles of uniform diameter to be produced.

Abstract: PURPOSE: To alternately move the liquid surface in a vessel up and down at regular intervals and to allow organismic agglomerated lumps on a supporting device to alternately contact with a liquid and a gas, in the equipment.  
     CONSTITUTION: In this equipment, sewage 30 is introduced into a sedimentation chamber 19 through an inlet pipe 2 and allowed to flow in a downwardly orientated stream. Then, the inflow sewage 30 is mixed with sewage treated to some extent and organismic agglomerated lumps, in the zone 19 to form a liquid mixture 15 that is allowed to continuously flow through a screen 10 in the equipment. An inverted box 13 contg. a contact medium 14 of an organismic agglomerated lump supporting device is filled with the liquid mixture 15 whose liquid surface is at a level 17 in a vessel. When an air blower 11 is operated, air is transferred with a pressure to the inverted box 13 through a pipe 12 to remove the liquid mixture 15 from the inverted box 13. By this replacement of the liquid mixture 15 with air, the liquid surface in the vessel is raised to a level higher than the level 17 and further, the liquid mixture 15 is moved up through the other contact mediums 18 and 20 to backwardly pass the liquid mixture 15 through the screen 10 and to dilute the inflow sewage 30 with the liquid mixture 15.

Abstract: PURPOSE:To perform immediately the processing for abnormality of various machine instructions and increase the instruction processing capability by setting the maximum time of execution needed for each of various machine instructions and producing an error signal after detecting that the next instruction is not started even when said maximum execution time elapses. CONSTITUTION:A machine instruction word is executed by a processor 1 of an instruction execution monitor device, and an instruction code signal PD showing the type of the instruction word is delivered together with an instruction execution starting signal FX. The time data signal TM showing the maximum for execution of instruction is delivered from an ROM2 which supplies the signal PD.

An error signal ER is applied to the processor 1 from an error signal generator 5 when the difference between the value indicated by the count signal CT and the initial value is larger than the maximum execution time of instruction. Then various machine instruction words are applied to the processor 1 from a machine word memory 6. Thus the instruction processing capability is increased.
