Title: Method for psk modulation and demodulation and device therefor
Inventor: YANAGISAWA SHIGEKI
IPC: H04L27/22
Filed: 1992-12-21
Abstract: PURPOSE:To provide the method for PSK modulation/demodulation and device therefor which reduce the error rate for demodulation of a PSK modulation signal in comparison with a delay detecting means and a synchronous demodulating means. CONSTITUTION:A modulator T sends the signal obtained by noninverting or inverting the carrier wave, whose instantaneous value starts with a prescribed value, in accordance with each bit value of information data Dot) as a PSK modulation signal P(t) from a terminal (e) of a switch circuit 6. Meanwhile, a demodulator R uses a wavelet converter 10 and obtains a value W(a, b), which is obtained by subjecting the PSK modulation signal P(t) to wavelet conversion by a function ha,b(t) for emphasis of only the phase change component of the PSK modulation signal P(t), to eliminate the noise included in the signal component other than the phase change component of the PSK modulation signal P(t). Simultaneously, a bit value corresponding to the polarity of the converted value W(a, b) is outputted from a polarity discriminator 13 to demodulate original information data D(t), thus improving the error rate.

Title: Exhauster
Inventor: MORITA SHINJI
IPC: B23Q11/00
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To significantly reduce the mist adhered to a fan by providing a baffle means for colliding the mist in a required position up to the fan of a duct. SOLUTION: The mist generated in the machining area of a cutting device is sucked through an exhaust port and advanced to a machining area communicating part 13. The mist advanced into the machining area communicating part 13 is advanced into a baffle means 12 through an outlet part 15, and most of it is collided to a baffle 17. The mist collided to the baffle 17 is adhered as water drops, soon fallen, and collected in the lower part of a housing 18. The liquid collected in the lower part of the housing 18 is discharged to a drain through a drain port 19. The liquid is thus never overflowed in the housing 18. Since most of the mist is adhered to the baffle 17 to form water drops in this way, the mist is hardly carried to a fan. Thus, the mist adhered to the fan can be significantly reduced.
