Title: Helium compressor
Inventor: KONDO MASATAKA
IPC: F04C29/04
Filed: 1990-11-09
Abstract: PURPOSE:To make a device compact by letting a discharge gas cooling pipe line penetrates a hermetic case from the outside so as to be set up in a coil shape wherein heat is exchanged with helium gas by the pipe line acting as a cooling means for helium, which is provided in the hermetic case housing a compression element. CONSTITUTION:A helium compressor has both a motor driven element 2 and a compression element 3 housed in the inside of a hermetic case 1, helium gas acting as refrigerant gas is led into the compression element 3 out of a suction pipe line 4 so as to be compressed by the compression element 3, and it is discharged outside out of a discharge pipe line 5 thereafter. In this case, as a cooling means for cooling helium gas, a pipe line 11 for cooling discharge gas is provided at a place close to a discharge pipe line 5 at an upper section within the hermetic case 1. The pipe line 11 for cooling discharge gas penetrates the case 1 inwardly from the outside, for example, it is set up in a coil shape at a position enclosing the discharge pipe line 5, so that cooling water is thereby circulated within the pipe line 11. This thereby permits discharge gas flowing in the discharge pipe line 5 to be thermally exchanged, thereby directly cooling discharge gas within the hermetic case 1.

Filed: 1999-10-26
Abstract: PROBLEM TO BE SOLVED: To make accurately calculable the degree of contamination, to take a proper measure such as replacement of developer when the degree of contamination becomes over an allowable contamination value and to prevent printing quality from being deteriorated by calculating the degree of contamination occurring because another developing substance flows in the developer based on a first light receiving signal and a second light receiving signal outputted from a photodetector. SOLUTION: When a first tube part 41 and a second tube part 42 are irradiated with an identical light quantity concerning the contaminated developer, the quantity of light transmitted through the tubes 41 and 42 are different and the first light receiving signal and the second light receiving signal are outputted as different values. When the concentration value of pure toner respectively estimated based on the first light receiving signal and the second light receiving signal are different, it is recognized that the transmitted light quantity is changed because a contamination substance is mixed in.  Besides, a reference table prepared by previously obtaining the concentration value of the pure toner and the degree of contamination corresponding to the values of the first light receiving signal and the second light receiving signal is arranged in a developer contamination measurement part 80. Then, the degree of contamination is calculated by referring the reference table to check to see whether both of the first light receiving signal and the second light receiving signal correspond to the identical concentration value of the pure toner or not.
