Abstract: A scroll compressor includes an oil recollecting pump for recollecting oil discharged from a shell, thus to effectively recollect oil discharged out of the compressor. A differential pressure hole is formed at a position where it communicates with compression chambers after a suction completion timing such that oil stored in an inner space of the shell can be supplied into the compression chambers using pressure difference between the high-pressure inner space of the shell and the low-pressure compression chambers, resulting in allowing oil to be smoothly supplied to a compression unit even during low-speed driving of the compressor and preventing beforehand an occurrence of a suction loss due to oil.

Abstract: A regenerator for restoring the originally encoded optical phase of a differential-phase-shift-keyed signal. In an embodiment, the regenerator simultaneously provides limiting amplification and reduces amplitude noise based on a phase-sensitive optical amplifier that combines a weak signal field of a degraded input data with a strong pump field supplied by a local oscillator in a nonlinear interferometer. The two fields interact through degenerate four-wave mixing, and optical energy is transferred from the pump to the signal and vice versa. The phase sensitive nature of the optical gain leads to amplification of a specific phase component of the signal, determined by the input pump-signal phase difference and the incident signal phase is restored to two distinct states, separated by 180° according to the original encoding. Simultaneously, gain saturation of the pump wave by the signal wave results in limiting amplification of the signal wave for removing signal amplitude noise.
