    摘要： A device and method to improve the bleeding of air from a brake cylinder usable in a drum brake. A first cylinder cavity 3 and a second cylinder cavity 4 are bored in the upper and lower sections respectively of the cylinder body 2, and a first piston 31 and a second piston 41 are housed to stroke within said cylinder cavity 3 and cylinder cavity 4 respectively, wherein piston 31 and a partition 21, separating said cylinder cavity 3 and cylinder cavity 4, form a first fluid chamber 32, and piston 41 and said partition 21 form a second fluid chamber 42. The cylinder also comprises at least one grooved fluid line 52 or an interior fluid line 53 to enable passage between said fluid chambers 32, 42; a brake fluid inlet line 51 that brings brake fluid into the second fluid chamber 42; and a brake fluid outlet line 54 that discharges the brake fluid into the first fluid chamber 32. Since the brake fluid inlet line is connected to the lower fluid chamber 2 and the outlet line is connected to the upper fluid chamber 1, brake fluid within the cylinder circulates from the bottom to the top, which makes effective use of the property of air to rise. This motion facilitates an easy and complete exhaustion of the air.

    摘要： A method of controlling the pressure in an incinerator for incinerating municipal refuse, industrial waste, etc. Exhaust gas from an incinerator typically passes through an exhaust gas cooler and an exhaust gas treating device and then discharged into the atmosphere by the action of an induced draft fan. In a method of controlling the pressure in such an incinerator for incinerating municipal refuse, industrial waste, etc. gas, e.g., part of the flow of exhaust gas induced by the induced draft fan or air taken in from the atmosphere, is added to a gas flow path upstream of the inlet of the induced draft fan through an addition gas line provided with an addition gas control damper. The addition gas control damper is controlled on the basis of an output from a furnace pressure controller such that when the furnace pressure is relatively high, the flow rate of the addition gas is reduced, whereas, when the furnace pressure is relatively low, the flow rate of the addition gas is increased.

    摘要： The optical receiver includes: a photoelectric conversion circuit for receiving an optical signal and converting the received optical signal into an electrical signal; a comparator for outputting a first determination signal (S1) when a voltage corresponding to the optical signal does not reach a first threshold value (TH1) and for canceling an output of the S1 when the voltage corresponding to the optical signal exceeds a second threshold value larger than TH1 during the S1 is output; a timing extraction circuit for generating a clock signal based on a frequency and a phase of the electrical signal obtained by the converting and for outputting a second determination signal (S2) when the generated clock signal does not satisfy a predetermined condition; a unit for causing the comparator to output the S1 when the S2 is output; and detects loss of optical signal while one of the S1 and S2 is output.
