IPC: B22D11/12
Filed: 1986-07-22
Abstract: PURPOSE:To miniaturize the titled device by forming coil grooves in both the inner circumferential side and the outer circumferential side of a cylindrical iron core in coincidence with a pitch angle of the grooves, winding a coil conductor between opposite coil grooves, and override-connecting the interval of coil conductors arranged in the circumferential direction at a coil end part. CONSTITUTION:Coil grooves 41, 42 are respectively formed in both the inner circumferential side and the outer circumferential side of a cylindrical iron core 4 with the interval of equiangular pitch in coincidence with a pitch angle theta of the grooves. Further coil conductors 51 are wound at every respective phases between coil grooves 41, 42 mutually opposed in the inner and outer circumferences. Furthermore the mutual interval of coil conductors of respective phases in the circumferential direction is override-connected at the coil end part projecting to the underside of the iron core 4. By this constitution, an override-connection in the circumferential direction is not present at the coil end part of the upper side of the iron core 4 and an obstacle-free passage of gamma-rays can be secured in the mutual interval of mutually adjacent conductors. Therefore both a radiation source 6 of gamma-rays which is a measuring means of the level of melted steel fed in a casting mold 1 and a detector 7 of gamma-rays can be provided to the position possibly near to the upper end face of the iron core 4.

Title: Turbidometer
Inventor: URUSHIBARA SHOTARO
IPC: G01N15/06
Filed: 1988-07-11
Abstract: PURPOSE:To improve the durability and to reduce the size of the turbidometer by using shape memory alloy for the driving mechanism for a cleaning brush and driving the cleaning brush with a displacing force at the time of the shape change of the alloy. CONSTITUTION:When a switch 18 is off, the shape memory alloy 11 is in a straight state and a brush main body part 14 is off a detection surface S. Then the turbidity of sample water can be measured. When the switch 18 is turned on at the time of cleaning, a current flows to the alloy 11 and a leaf spring 12 to generate heat. The alloy 11 restores itself to bend in a direction (a) as the temperature rises by said heat generation and then enters the state shown by an imaginary line by passing the detection surface S. Then the current is cut off, the alloy 11 is cooled and returns to the straight state with the force of the spring 12. In this reciprocation, the detection surface S is swept by the main body part 14 and cleaned. Consequently, the turbidity is accurately measured.
