Title: Afc device for psk receiver
Inventor: YAMAMOTO TETSUO
IPC: H04L27/227
Filed: 1993-10-20
Abstract: PURPOSE:To follow fast frequency fluctuation and to converge a phase error at high speed. CONSTITUTION:A 4-phase PSK modulation signal is orthogonally detected by an orthogonal detector 12, and it is passed through a root cosine filter 17, and is sampled with a symbol period at a sampling circuit 18, and the phase error is detected by a phase error detecting part 19. When the absolute value of difference between the phase error and the one last time exceeds pi/4, a correction part 21 adds or subtracts pi/2 so as to set the absolute value of the difference at a value less than pi/4, and supplies it to a low-pass filter 22, and controls a local oscillator 13 by the output of the filter. When the phase of the output of the filter 22 exceeds pi/2, a correction reset part 31 detects the fact, and clears the internal state of the filter 22, and also, interrupts correction control for the local oscillator 13, and interrupts correction by a correction part 21.

Abstract: PURPOSE:To enable the relative alignment of two members with higher accuracy, and to sufficiently enlarge its detection range, by a method wherein the detected output at the moment that the oscillation position comes into an integer multiple of the pitch of fine alignment patterns is sample-held at the time of rough alignment. CONSTITUTION:Coarse alignment allows the oscillation of a mask 12 by setting the mask oscillation amplitude at a value for coarse alignment (an integer multiple of a pitch P1) according to instructions from a control unit 15. On the other hand, an alignment light passes through the mark 13 of the mask 12 and brought into the irradiation of the mark 23 on a sample 22, and the reflected light from the mark 23 is detected by a photoelectric converter 25 and then inputted to the control unit 15 though a signal processing circuit. There, the corrected amount of coarse position is determined, and coarse alignment is accomplished by a drive mechanism 29. Fine alignment allows the oscillation of the mask likewise as coarse alignment by setting the mask oscillation amplitude at a value for fine alignment (at a fraction of the value of a pitch P2). Signal detection, signal processing, and positional correction in the later process are completely the same as in the case of coarse alignment.

Title: Transport apparatus utilizing gas stream
Inventor: MARUI TOMOTAKA
IPC: B65G53/42
Filed: 1984-12-15
Abstract: PURPOSE:To facilitate the feeding of the transported articles and operate the captioned apparatus under the optimum conditions corresponding to the transport load for the transported article by installing a mechanism for adjusting the width of the annular gap formed between the outer wall at the top edge part of a transported-article feeding pipe and the inner wall of a funnel pipe. CONSTITUTION:The gas sent from a gas feeding pipe 24 is supplied into a conduit at high speed in the oblique direction along the inclined surface of a funnel part from an annular gap between the funnel part and a transported- article feeding pipe 3. A spiral gas stream is formed in the conduit 1, and the pressure at the outlet of the transported-article feeding pipe 3 is lowered. The degree of the pressure lowering is larger as the width of the annular gap is smaller and the gas flow rate is larger. The adjustment of the gap is performed by transferring the pipe 3 by a spur gear 51, gear 52, and a motor 53. When a negative pressure is generated, the transported articles supplied from a hopper 4 is blown into the spiral gas stream, and feeding is facilitated. Therefore, the pressure can be adjusted to the negative pressure necessary for automatic feeding of the transported articles at the outlet of the feeding pipe 3 by the gas amount corresponding to the transfer load, and efficiency can be improved.
