Title: Reproducing device for digital information recording disc
Inventor: IMAI TAKAHIRO
IPC: G11B20/10
Filed: 1985-05-13
Abstract: PURPOSE:To reproduce even video data inputted from the external by providing an external input writing means which writes a digital video signal in a picture memory in the same writing method as a picture memory writing means in a device. CONSTITUTION:A picture memory writing part 9 separates the digital video signal from the digital signal inputted from an error detecting and correcting part 7 and writes it in a picture memory 11. An external input writing part 12 converts the analog video signal inputted from an external input terminal 13 to a digital video signal and writes it in the picture memory in the same method as the picture memory writing part 9. That is, the signal is written while allowing a position on the screen and that of an address of the memory to correspond to each other. A video signal processing part 14 reads out stored contents of the picture memory 11, namely, video data of a disc or video data inputted from the external and subjects read video data to D/A conversion and outputs video data to a video terminal 15 as an analog video signal. Thus, video data other than video data recorded on the disc is reproduced.

Abstract: PROBLEM TO BE SOLVED: To attain a broad frequency band by inserting a constant impedance isolator to at least one of input and output sides of a 1st delay line in the distortion compensation amplifier provided with a distortion elimination circuit that cancels a distortion component generated in a main amplifier to provide a multi-frequency amplifier signal to suppress multiple reflection. SOLUTION: Isolators 40a, 40b, 50, 60 are added to a conventional circuit. The isolator 40a or 40b with a constant impedance having a broad frequency band characteristic is inserted to an input side or an output side of a delay line 6 of a distortion detection circuit 20 to suppress multiple reflection in a path of components 1-6-7-8 and to make a broad frequency band stable. Furthermore, the isolator 50 is inserted to an output side of a main amplifier 5 to make an output impedance of a power combiner 7 stable over a broad frequency band. The similar effect is obtained by inserting the isolator 60 to a pre-stage of a power distributer 2 to make an input impedance of the distortion detection circuit 20 stable over a broad frequency band. Thus, the amplitude frequency characteristic over a broad frequency band is obtained.

A scanning means (X scanner 14, Y scanner 16, relay lens 18, ftheta lens 20) scans a laser beam produced by the device 12 on the surface of the mask 46. When the laser beam is irradiated on the mask 46, the laser beam is absorbed by a light absorbing layer 38. The absorbing layer 38 generates heat and a liquid crystal 42 is transparent because its molecules align in order, and is heated until it becomes an isotropic liquid crystal phase. Thereby, a good pattern shape can be obtained.

Abstract: PURPOSE:To continuously hot-dip galvanize a steel strip with a high rate and a large capacity by filling the upper part of an inlet-side chamber communicating with an outlet-side chamber at the bottom with molten zinc, filling the lower part and outlet-side chamber with a high-sp.gr. material not adhesively bonded to the strip and passing the strip through both chambers. CONSTITUTION:A pot 2 for continuously hot-dip galvanizing a steel strip 1 is separated by a partition 3 into two chambers, and the two chambers communicate with each other at their bottom. The upper part of the inlet-side chamber is filled with molten zinc 5, and the lower part of the inlet-side chamber and the outlet-side chamber are filled with the molten material 6 such as lead having a higher sp.gr. than zinc and not adhesively bonded to the strip 1. The space 7 over the bath surface of the outlet-side chamber is preferably filled with a gaseous mixture of nitrogen and hydrogen to prevent the oxidation of the molten material 6 and the deposition of dross. The annealed steel strip 1 is passed through the pot 2 from the inlet-side chamber to the outlet-side chamber with the aid of a pot roll 4. Consequently, the excess zinc deposited on the strip 1 surface is pushed up by the high-sp.gr. molten material 6 and removed.
