Title: Digital phase synchronization circuit
Inventor: OYAMA KOYO
IPC: H03L7/00
Filed: 1991-05-28
Abstract: PURPOSE:To simply realize the phase synchronization circuit with a simple, small circuitry and high accuracy by constituting of two sets of positive polarity delay buffer blocks, a latch circuit, an encoder circuit and an (N-1) selector or the like. CONSTITUTION:In input buffer 1 receives a reference clock input signal and distributes the signal into two, the one is outputted from an output buffer 4. The other distributed signal is given to a flip-flop 7, in which the clock is 1/2 frequency-divided. Moreover, an input buffer 2 receives the clock input signal and distributes it into two, the one is given to plural buffers 3 connected in series, from which the signal is sequentially delayed while the positive polarity is kept. A flip-flop 6 latches a signal of a 1/2 frequency division flip-flop 7 by using other distribution signal from the input buffer 2 as a latch timing. Furthermore, a buffer 11 obtains plural signals resulting from sequential delay of an output signal of the flip-flop 6.

Abstract: PURPOSE:To analyzing characteristics such as film thickness, electron conductivity and rugged state of a thin film sample surface by casting rays of vacuum UV rays and visible wavelength to the sample surface to ionize the surface molecules and detecting the quantity of the generated electrons, ions and holes. CONSTITUTION:A high voltage Va is impressed between electrodes 6a and 6b of a discharge tube 6 to generate discharge and the generated UV rays are focused by a lens 7. The surface of the thin film sample 3 is irradiated by the focused rays. The irradiated part is ionized and the electrons released by the same are captured by an intermediate electrode 8 impressed with a positive voltage Vb. Electron current flows through the sample from a collector electrode 2 to the holes generated on the sample surface.

The film thickness of the part irradiated by the UV rays can be determined from the curve Vb-Ib of the voltage Vb and the current Ib. The film thickness and electrical conductivity of the respective parts 9 of the sample are determined by moving the sample to change the irradiation position.

When the uncorrectable error is generated by the sticking, etc., of the dust to the optical recording media, an information processing circuit 18 changes over a switch circuit 101 in accordance with the detecting signal by the circuit 103. Thus, the special code from a special code generating circuit 104 is written through the laser 5 to the next sector, further, the data, in which the error occurs, are recorded to the sector again, and until the error generation is eliminated, the same repetition is repeated. Thus, the error generating part is clarified and the recording with a high reliability is executed.
