Title: Method and device for detection of tracking error signal with information reading device
Inventor: KANEKO NOBUYUKI
IPC: G11B7/09
Filed: 1982-05-20
Abstract: PURPOSE:To eliminate the variation of sensitivity of a tracking error signal due to the variation of amplitude level of the output signal of a photoelectric transducer, by detecting the position information contained in the output signal of the photoelectric transducer to obtain the tracking error signal. CONSTITUTION:When a light spot is at the right of a track, the output signal of an LPF21 is set at a low level by the voltage obtained when the light spot is on the center of the track. At the same time, the output signal of an LPF22 is set at a high level in the same way. Then a tracking error signal with which the light spot is shifted to the right of the track is obtained through the differential amplification of a differential amplifier 23. While the levels of the output signals of filters 21 and 22 change in the direction opposite to a case where the light spot is shifted to the right of the track. Thus a tracking error signal with which the light spot is shifted to the left of the track is obtained through the output terminal of the amplifier 23.

IPC: H04B3/10
Filed: 1988-04-07
Abstract: PURPOSE:To measure line equalization and to determine optimum transmission speed by one training by providing a mean square error calculation circuit calculating the mean square error during a TCF(training check) signal period to an equalizer. CONSTITUTION:The number of times of accumulation N is set to '2400' by using the CCITT modem recommendations V29. In accordance with the CCITT recommendations T30 with respect to the facsimile protocol, as the TCF, a consecutive '0s' signal for 1.5sec+ or -10% is sent. Thus, the N is set to '2400', then the square error is accumulated for 1sec. Then an error rate versus S/N curve for a V29 modem is plotted succeedingly to obtain the S/N with respect to the user allowable error rate. Then the mean square error accumulation is obtained by the square error accumulation level QL with respect to the obtained S/N to plot a threshold level TH. When the value QL is larger than the TH, 9600bps is selected as the optimum transmission speed and when larger, 7200bps is selected as the optimum transmission speed.

Abstract: PROBLEM TO BE SOLVED: To provide the method and device for improving efficiency in collecting spatters or fumes scattering along the surface of a material. SOLUTION: In a laser beam machine for machining a work W by emitting a laser beam LB from the nozzle 27 of a machining head 29, the shielders 35, 37 which enclose the upper side from near the upper surface of the work in the entire circumference of the machining head are installed at least double at prescribed spaces apart, with a dust collecting duct D sucking scattering S produced during machining. Consequently, most of the scattering S so produced is shielded with the shielder 35 closest to the machining head 29 and sucked by the dust collecting duct D. Further, the scattering S leaked outside through the nearest shielder 35 is shielded by the next shielder 37 and sucked by the duct D. When the scattering S passes under the shielder 35 closest to the machining head 29, a part made of a soft material 39 at the lower end of the shielder 35 reduces the speed of the scattering S.
