Title: Feedback pump for nuclear reactor
Inventor: SAITOU MASAHIRO
IPC: F04D7/06
Filed: 1982-08-27
Abstract: PURPOSE:To prevent generation of cracks by giving the mixture flow of high- temperature reactor water with the low-temperature purging water, which arises at the surface of the pump shaft and the inside surface of the casing cover, the form of a flow containing high-frequency components and thereby reducing thermal stress originating from this mixing. CONSTITUTION:The purging water 13 injected into a seal chamber 12 of a feedback pump for nuclear reactor passes through a gap 9 formed between the pump shaft 1 and casing cover 4 to come above an impeller 2, where the pump shaft 1 is equipped with a plurality of labyrinths 19 with different pitches, so that rotating the pump shaft 1 in the direction of Arrow 21 will induce a downward flow 23 and another flow 24 with different magnitude therefrom, and thus the purging water 13 is given the form of a flow containing high-frequency components to assure reduction of thermal stresses. Accordingly, temperature changes likely to occur due to mixing of the purging water with the high-temp. reactor water 14 at the surface of pump shaft 1 and at the inside surface of the casing cover 4 can be well eliminated to assure prevention of crack generation.

Title: Positioning device
Inventor: KITANO HIROSHI
IPC: G05B19/414
Filed: 1980-10-22
Abstract: PURPOSE:To change positioning points easily by storing the set value of a positioning point in a storage device, and by comparing this value with the position corresponding value of a moving workpiece, detected by a position detector, by a coincidence detector. CONSTITUTION:A positioning request from an external controller 21 is set to a positioning-request flag 20, and a control circuit 25 stores a set value, corresponding to a positioning point from the flag 20 in a set-value memory 30. The position of a workpiece is detected by the position coders 5a-5n of a position detector 5, and their values are inputted to a coincidence detecting circuit 35 through a selecting circuit 36. The circuit 35 compares the set value from the memory 30 with the detection value passed through the circuit 36 and, when the two are coincident, sets a coincidence detection signal to a positioning end flag 40 to output it to the device 21 through an output circuit 41. Consequently, the positioning points are changed easily only by rewriting the storage contents of the storage device.
