Abstract: PURPOSE:To rapidly detect the phase difference of high speed rotation, by fixing discs overlapping with each other at the outer peripheral parts thereof respectively to two parallel shafts rotating in synchronous relationship and detecting a plurality of the windows each composed of an involute curve provided to the overlap part of said discs by a slit and a photocoupler. CONSTITUTION:Shafts 3, 4 are connected in the relationship of master and servant to be rotated by a male rotor 1 and a female rotor 2. Discs 9, 10 overlapping with each other at the outer peripheral parts thereof are fixed to the end parts of the shafts 3, 4. A plurality of light pervious windows 17, 18 whose opposed surfaces form involute curves 17a, 17b, 18a, 18b are provided to the overlap part at equal intervals. The light from a light emitting element 11 passes through the windows 18, 17 and a light passing window 22 formed by the observing window 15 of a light blocking plate 16 to be inputted to a light receiving element 12. When the shafts 3, 4 are shifted in a phase, the size of the light passing window 22 changes. The output change of the light receiving element 12 is detected by a detection circuit 102, amplified by an amplifying circuit 103 and filtered by a filter 104 to be outputted for detection of phase difference. By this method, phase difference is rapidly detected even during high speed rotation. This apparatus is suitable for the female and male rotors of a screw type compressor.

IPC: F23C10/18
Filed: 1983-03-17
Abstract: PURPOSE:To easily remove high temperature clean combustion gas by a low-cost system, by a method wherein combustion residue is removed to the outside of a combustion furnace together with a combustion flow to change its direction centering around a horizontal direction acting as an axis. CONSTITUTION:Combustion gas (b) including combustion residue (c) fed through a combustion exhaust hole 7 to the outside of a furnace is momentarily changed in the direction of its flow by means of a duct B which is bent at 180 deg. to form the shape of a hair pin. The change in the direction of the flow causes the combustion residue (c) contained in the combustion gas (b) to be converged to the bent outer periphery side of the duct B bent in a hair pin through a centrifugal force, and when its direction is changed by about 180 deg., the residue is separated from the combustion gas (b) through a total sum of a centrifugal force and acceleration of gravity. The combustion residue (c) separated from the combustion gas (b) is taken-out from an air lock valve 13 to the outside after passing through an exhaust pipe 12. This permits easy taking-out of high temperature clean combustion gas by a low-cost system.
