Title: Optical rectifier
Inventor: SAWA TAKESHI
IPC: G01R15/24
Filed: 1990-09-20
Abstract: PURPOSE:To carry out measurement of a high reliability by arranging the principal axis of an analyzer so as to be inclined by 45 degrees to one of three linearly polarized waves emitted from a light source, and by comparing the outputs of both the phase detecting system and the light-intensity detecting system. CONSTITUTION:Linearly polarized light sources 6a, 6b, 6c emit a linearly polarized light E0 of 0 deg., a linearly polarized light E60 of 60 deg., and a linearly polarized light E120 of 120 deg. respectively, and after they have passed through a Faraday element 3, they are subjected to the Faraday rotation by the angle of theta in proportion to the intensity of magnetic field H, and becomes E'0, E'60, and E'120. They pass through an analyzer 4 whose principal axis is inclined by 45 degrees, and only the principal-axial components of the analyzer 4 are composed and incident on an optical detector 5. The output signal of the detector 5 via the route 12 is caused to take a phase modulation waveform proportional to 3A/2pi.cos(omegat-2theta) by a band-pass filter 7. By comparing this phase modulation waveform with the reference phase of a driving circuit 9, a signal P1 being proportional to theta is output. The output of a sampling circuit 10 is supplied to a low-pass filter 11, and the output signal P2 of the filter 11 takes the waveform of A/12(1+sin2theta). Then, the output P1 is compared with the output P2 by means of a comparison circuit 14, and if there is any abnormality, an alarm ALM is emitted.

Abstract: PURPOSE:To arbitrarily adjust the quantity of combustion immediately after the ignition of a kerosene stove, to prevent odor from generating at the time of ignition and fire extinguishment, and also to prevent non-uniform flame from being generated, by rendering a liquid fuel into bubbles and subjecting the same to continuous combustion. CONSTITUTION:A sintered metal element 2 is disposed within a bubble collecting cylinder 3, and a wind box 4 for supplying combustion secondary air is provided on the upper outer side. When a gas is charged through a gas supply pipe 6 to the sintered metal element 2, the gas is supplied through the holes of the element 2, and a fuel oil rises up within the bubble collecting cylinder 3 while bubbling. Hence, air necessary for the combustion is supplied through a gas supply pipe 7 and the fuel oil is burnt. The quantity of air from the gas supply pipe 6 is increased to increase the quantity of bubble produced. By increasing the quantity of air from the secondary air pipe 7, it is possible to increase the quantity of combustion. Further, by bringing an ignition source into direct contact with bubbles produced, it is possible to ignite the bubbles produced, and the discharge of air to the gas supply pipe 6 is stopped whereby the bubbles are eliminated and fire is extinguished immediately and odor after the extinguishment is not felt. Further, it is possible to prevent local heating of a material to be heated by increasing the surface viscosity and lowering the surface tension.
