Title: Mechanical lubricator for oil rotary vacuum pump
Inventor: KOIKE EIJI
IPC: F04C25/02
Filed: 1982-08-02
Abstract: PURPOSE:To make oil securable in an exhaust valve part at all times and eliminate any influence on the performance of lubricator due to a level drop as well as to make low noisy operation achievable, by attaching an exhaust valve cartridge to an exhaust valve part, while carrying out forced lubrication by means of an oil pump. CONSTITUTION:During operation on a vacuum pump 1, an oil pump 18 is also driven together and thereby oil is continuously fed to the inside of an exhaust valve cartridge 11, then part of the oil is so designed as to be put back inside an oil tank through an overflow hole 14 so that a fixed quantity of oil is secured inside the cartridge 11 at all times. On the other hand, in time of high load operation, oil is discharged outside from the inside of a cartridge chamber through a pass hole 13 and thereby even if a drop in the oil level temporarily happens, as the oil is fed out of the oil pump witout interruption, deterioration in operating performance never occurs. In addition, the exhaust valve cartridge 11 fulfills both roles as an initial muffler and a baffle, bringing its effectiveness into full play for reducing not only the spatter of oildrops but also exhaust noises.

Filed: 1989-05-30
Abstract: PURPOSE:To attain always accurate binarization immune from noise, amplitude fluctuation or fluctuation of DC component by obtaining tendency of increase/ decrease after digital conversion of an input signal and binarizing the result. CONSTITUTION:An analog input signal C is digitized by an A/D converter circuit 1. The digitized signal is stored tentatively to either of latch circuits 2, 3 at the edge of an external clock signal F. Then a subtraction circuit 4 subtracts output signals E0-E7 of the latch circuit 3 from output signals D0-D7 of the latch circuit 2 to generate a borrow signal G. The borrow signal G and the external clock signal F are exclusively ORed to represent the gradient of the input signal C correctly. Thus, the borrow signal G and the external clock signal F are given to the EXOR gate 5 and its output signal H is stored by using a latch circuit 6 with a signal I. A binarizing signal is obtained from the output of the latch circuit 6.
