Title: Oil separator for recovering fluorocarbon
Inventor: NAKAJIMA AKIRA
IPC: F25B45/00
Filed: 1994-06-24
Abstract: PURPOSE:To reduce the quantity of a fluorocarbon remaining in recovered oil as much as possible by forming an oil recovery vessel of a pressure resistant vessel, coupling the resistant vessel to the suction port of a fluorocarbon recovering apparatus body to always evacuate in negative pressure in the recovery vessel, and exposing the fluorocarbon remaining in the recovered oil within a negative pressure environment during the recovering operation. CONSTITUTION:Oil O separated from a fluorocarbon gas by a fluorocarbon recovering oil separator 100 is transferred to an oil recovery vessel 400 by opening a cock 402. Then, the cock 402 is closed, a cock 405 is opened, and fluorocarbon recovering operation is conducted. Thus, the interior of the vessel 400 is held in a negative pressure by the suction force of a fluorocarbon recovering apparatus body 200 during the recovering operation. Accordingly, the fluorocarbon tends to be easily released from the oil O by the negative pressure, and the quantity of the fluorocarbon remaining in the oil can be reduced. Further, the vessel 400 is heated to further increase the quantity of the fluorocarbon to be released from the oil.

Filed: 1982-08-20
Abstract: PURPOSE:To control optionally the phase of a sampling clock pulse which samples an input video signal when a TV video signal is delivered after conversion into a PCM, by controlling the delay time of a variable delay line in response to the output signal of a differential amplifier. CONSTITUTION:When the output of the final stage of a shift register 3 varies from E0 through E8 for each clock, the sample value is controlled so that the outputs E0-E8 are equal to the output value of an averaging circuit 8. As a result, the phase of the output clock signal of a clock generator 7 shifts to a synchronous state from an asynchronous state. Therefore a strobe pulse is delivered at least once and synchronously with a specific order of clock of the generator 7 within a burst signal period for each period of 1H. The outputs of the register 3 and the circuit 8 are latched to registers 4 and 4' respectively by the strobe pulse. Then a variable delay line 9 is controlled so as to obtain equal contents between both registers 4 and 4'.
