Title: Digital pll circuit
Inventor: HAYASHI HIDEKI
IPC: H03L7/093
Filed: 1994-12-13
Abstract: PURPOSE: To obtain a reproducing clock signal accurately synchronized with the phase of a read signal by detecting a phase error generated in the read signal from a recording medium, generating an oscillation data signal sequence and obtaining a square wave signal converted from the signal sequence as a clock signal. CONSTITUTION: A pickup 1 supplies recording information recorded in a recording disk 3 to a head amplifier 4. The amplifier 4 supplies an amplified read signal to an A/D converter 5. The A/D converter 5 converts the amplified read signal into a sample value (q) and supplies the value (q) to a digital PLL circuit 40 and a time axis correcting circuit 20. In the PLL circuit 40, a phase detecting circuit 41 detects a phase error in the read signal and a digital VCO 43 obtains a sine waveform signal with the period of data. A comparator 46 inputs a reproducing clock signal (e) and supplies the signal (e) to the converter 5, the circuits 20, 41 and a digital filter 42. A viterbi decoder 30 catches the sample value (q) corrected by two time axes through the circuit 20 as a time sequence to obtain reproduced data.

Title: Optical recording medium and optical recording method
Inventor: MOCHIZUKI HIDEAKI
IPC: G11B7/24035
Filed: 1987-12-08
Abstract: PURPOSE:To enhance the flexibility of production and to reduce the cost at the time of small-quantity production by constituting the title medium in such a manner that a change in optical properties is maintained even for reproducing light of the wavelength which does not belong to a specific absorption band. CONSTITUTION:This optical recording medium is constituted by providing a transparent optical recording layer 2 which is transparent except in a specific absorption wavelength region on a transparent substrate 1, providing a transparent layer 3 thereon and providing a reflecting layer 4 further thereon. The optical recording layer 2 is so constituted as to generate the change in the optical properties by absorbing the recording light belonging to the specific absorption band and to maintain the change in the optical properties even with the reproducing light of the wavelength which does not belong to the specific absorption band. Since the change in the optical properties generated at the time of recording covers nearly the entire wavelength region, the signals are detected as the discontinuity of the reflected light for the reproducing light which does not belong to the absorption wavelength region of the recording layer 2 (i.e., the recording layer is transparent to the reproducing light). The need for the process for producing a costly stamper in the manufacture of CDs is thereby eliminated and the small-quantity production of the CDs and CD-ROMs of the same software is executed at the low cost with ease.

IPC: B32B27/08
Filed: 1990-11-15
Abstract: PURPOSE: To obtain a multilayered film structure having oxygen, carbon dioxide dioxide and moisture barrier properties by constituting the same of a first polymer film having low permeability to moisture and a heterogeneous polymer blend film containing a gas barrier polymer and a second polymer distributed in the gas barrier polymer so as to allow the heterogeneous polymer bland to adhere to the first polymer. CONSTITUTION: A multilayered film structure has three layers, that is, a non- uniform inner layer prepared from a blend of a usually polar polymer and a non-polar polymer and outer layers containing a non-polar polymer same to or different from the non-polar polymer forming the non-uniform inner layer. The non-polar polymer is present in the inner layer in an extremely fine particulate distribution state imparting good adhesion between the inner and outer layers without using a binder layer. The surface rich in non-polarity of the non-uniform film layer ensures good adhesion to the outer layers by the simple mutual impregnation of individual layers at an interface and the entanglement of polymer chains having properties similar to those of the outer layers.
