Title: Digital recording and reproducing system for video signal
Inventor: SASAKI MOTOHIRO
IPC: H04N5/92
Filed: 1987-04-30
Abstract: PURPOSE:To obtain a reproduced picture free from degradation of picture quality by providing plural kinds of transposing pattern for transposition of the recording order and selecting a transposing pattern by M series and transposing recording positions of digitized video signals in accordance with the selected transposing pattern to record these video signals. CONSTITUTION:In case of transposition with each signal recording track as a unit, an M series generator 33 outputs the output once in a prescribed period to select the generated pattern of a pattern generator 34 at random. The pattern generator 34 generates individual contents of the pattern selected by M series once for each signal recording track to transpose the recording position of the signal recording track in the prescribed period. Consequently, recording positions of signal recording tracks, into which one field is divided, in the prescribed period are interposed at random and are recorded. Since picture lines specially reproduced at various speeds and scanned are moved at random on a picture, the reproduced image free from noise bar and degradation of picture quality is obtained by correction based on field correlations and frame correlations.

Title: Electrode plate for nonaqueous electrolyte secondary battery and its manufacture
Inventor: MIYANOWAKI SHIN
IPC: H01M4/139
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To enable a current collector to be accurately coated with coating liquid in a pattern at a high speed and reduce the loss of expensive active substance by coating only a required region of the current collector with the coating liquid by the use of a nozzle coating device. SOLUTION: While coating liquid is supplied under pressure from a coating liquid tank 9 to a liquid container 6 via a controller 10, the container 6 (a nozzle 3) is linearly moved in an X direction by an X-direction driving device 13, thereby forming a first coating line. Since the coating liquid isn't discharged from the nozzle 3 upon completion of the coating of the first coating line, the thickness of a coated surface 7 at the terminal end of the coating line cannot become thicker than other portions. Subsequently, after a current collector 5 is fed by one pitch in a Y direction, the nozzle 3 is driven in a direction opposite to that of the first coating line by the device 13, thereby forming a second coating line. By repeating the above-described lines, the predetermined coated surface 7 is formed on the current collector having a given width.  A coating film can be formed by drying the coated surface 7.

Title: Undesired signal preventing circuit for programmable lsi
Inventor: GOTOU MASAHIKO
IPC: H03K17/00
Filed: 1979-08-16
Abstract: PURPOSE: To obtain an extremely economical undesired signal preventing circuit, by adding the pull-down resistance to the signal pin of the programmable LSI.  
     CONSTITUTION: The pull-down resistance 10 obtained from the fixed relational formula is connected between the signal line 11 which connects the signal pin 1a of the programmable LSI1 and the buffer gate 6 and the earth. The reset signal A is applied to LSI1 to put pin 1a under the input mode and the high-impedance state for a fixed time. During this period, the resistance 10 keeps pin 1a at the logic 0, and thus the undesired output signal is reduced not to emerge to the output signal line 3. The pin output is set to the logic 0 at the moment when pin 1a is set to the output mode. After this, the real signal output produced from the control program inside the LSI1 is delivered with pin 1a set to the logic 1. Accordingly, the undesired signal can be blocked in an extremely simple way and just by a low-cost resistance.

Abstract: PURPOSE:To obtain a low-costing exposure device having a reduced number of movable components and still having high reliability, by providing, between a projection lens of the exposure device and a wafer, a spectral diffraction means which substantially transmits exposure light and substantially reflects alignment light which is non-printing light. CONSTITUTION:White light emitted from a light source 15 is collected by a reflection mirror 16, passes through a collimator lens 14 and is collected by an objective 10 onto a wafer 8. Since there are latent images of a wafer alignment mark and an alignment mark of a reticle 5, the light reflected from these latent images again enters into the objective 10. The light is then reflected by a beam splitter 11 and image formed by a collection lens 12 on an image pickup tube 13. The image pickup tube can observe simultaneously the wafer and reticle alignment marks and detect a positional error between them. An X-Y-Z stage 9 can be moved so as to correct the positional error to a desired value. In this manner, alignment between the R-AA mark and the W-AA mark is completed.

Abstract: PROBLEM TO BE SOLVED: To obtain a phase difference film capable of making expression uniformly with high fidelity over the entire area of visual fields by controlling the fluctuation in the tension applied on the film under stretching to a specific range. SOLUTION: The fluctuation in the tension applied on the film under stretching is controlled to the range of ±1% at the time of producing the phase difference film by uniaxial stretching a thermoplastic resin film.

Abstract: PURPOSE:To improve efficiency of irradiation and also to miniaturize a unit by setting the magnitude of a constant-level signal, subtracted from the output signal of a photo-detector according to picture information. CONSTITUTION:When picture information 12 resides on the surface of original 3, relatively high black-level signal (b) is obtained from amplifier 20 and substrated preadjusted constant-level signal (c) by subtracter 22.

On the other hand, when picture information 12A is on the reverse surface or original 3, a slightly low level black signal is obtained and signal (c) is subtracted from the signal. In this case, the level of signal (c) is so set that signal b-c will be below level 0. Therefore, no read signal appears at output terminal 24.
