Title: Codec for time base compressed multiplex transmission
Inventor: KITAGAKI KAZUKUNI
IPC: H04N11/24
Filed: 1987-01-21
Abstract: PURPOSE:To simplify a circuit scale by providing a means for storing luminance signals for one horizontal scan period, and a means for storing chrominance components by bands for plural horizontal scan periods, and permitting a switching means to switch the actions of a coder and a decoder. CONSTITUTION:A memory 1 for one horizontal scan period H of the luminance signals Y generates a first delay means, and memories 2-7 for 2H of wide band chrominance components C and memories 8 and 9 for 1H of narrow band chrominance components C generate a second delay means with a tap. While the coder operates, the memories 2-7 work as the delay means of a vertical filter, and while the decoder operates, the memory 1 and the memories 2-7 as phase correction delay means, and the memories 8 and 9 as the delay means of an insertion filter. With switching a large parts in a memory area by the switching means and sharing them, the circuit scale is minimized and the number of elements and an occupied area can be reduced.

Title: Storing method of picture information
Inventor: IKEDA YOSHINORI
IPC: H04N1/21
Filed: 1983-01-24
Abstract: PURPOSE:To store picture information by a storage means whose capacity is small by using an aggregate of at least two very small picture elements as a unit picture element, and storing a rank number corresponding to the number of picture elements of a black or white level for constituting the unit picture element, as a density rank number. CONSTITUTION:Among 2X2 very small picture elements of a unit picture element, the number of black levels is used as a density rank number, and stored as picture information of each picture element. Writing of a video signal to a buffer is ececuted at every one line in order from ''1'', and as for readout, two lines are executed simultaneously at every group of the buffers 1 and 2, and 3 and 4. A binary counter 7 divides a signal into two bits each, the number of black level picture elements is counted at every line by bit counters 8, 9, respectively, and it is added at every two bits, and outputted to a multiplexer 14. On the other hand, when writing the signal to the buffers 1, 2, it is read out of 3 and 4, and the number of picture elements of a black level among the very small picture elements of 2X2 is outputted as a density rank number of 3 bits from an adder. In the multiplexer 14, at every two-line portion of the original picture element data, adders 12, 13 are selected and stored as picture information.

Filed: 1992-01-23
Abstract: PURPOSE: To facilitate time delay adjustments by providing a time delay generating means which guarantees the delay time difference between a primary clock signal and a master clock signal on a master clock output line within a specific time range. CONSTITUTION: The master clock signal distributed to master clock output lines is supplied to a circuit through a line 140.

Namely, when a fuse 166 is not disconnected, the multiplexer 148 outputs the clock signal from an inverter 142 after it is delayed by 8 gates. When the fuse 166 is blown by applying a sufficient current to a terminal 162, the multiplexer 148 outputs the undelayed master clock signal.

Title: Vertical magnetic recording and reproducing device
Inventor: KIMURA HISAO
IPC: G11B5/53
Filed: 1983-01-24
Abstract: PURPOSE:To increase recording density by performing two-dimensionally vertical magnetic recoding by using plural pieces of moving main magnetic poles. CONSTITUTION:A magnetic tape 1 having a two-layered construction is curved in a sectional circularly-arcuate shape and is sandwiched between a rotary disk 11 and an auxiliary magnetic pole 13. The tape 1 is moved by a driving mechanism in the direction at a right angle to the rotating direction of the disk 11, i.e. in the same direction as the direction of the revolving shaft 16 of the disk 11. Since the rotating direction of main magnetic poles 10 intersects orthogonally with the traveling direction of the tape 1, the recording on the tape 1 has a bitter figure. In other words, the one line intersecting roughly orthogonally with the traveling direction of the tape 1 is a pattern by the one pole 10 and the recording by the four poles 10 appears consequently in the traveling direction of the tape repeatedly by each one line. The vertical magnetic recording at the highest density is thus accomplished by utilizing the min. magnetic doman unit on the tape 1 in the two-dimensional direction in the X, Y directions by the above-mentioned constitution.

Abstract: PROBLEM TO BE SOLVED: To surely prevent skull formation at a casting pool by providing a side part opening from which a molten metal is allowed to flow outward in a metal supply nozzle and providing an opening through which a nozzle lower side is communicated directly with a nozzle trough inside in a nozzle bottom part. SOLUTION: The molten metal is allowed to flow out near the casting pool 68 whole surface as two injection flows directing sideward/outward through side part openings 64 so as to be allowed to collide with a casting roll 16 cooling surface immediately near a casting pool 68 surface. The opening 101 can be an additional source to allow metal flow to flow to the casting pool 68 near an underside of a nozzle, a relatively large gas bubble is prevented from stagnating/accumulating overall at an underside of the nozzle. In particular, it is important the side pat openings 64 are arranged at inner ends of two metal supply nozzle 19 half parts. By this method, the molten metal is sufficiently supplied near a center region, skull formation is surely prevented in this region of the pool.

Title: Dry etching method
Inventor: YANAGIDA TOSHIHARU
IPC: H01L21/28
Filed: 1994-02-01
Abstract: PURPOSE:To provide a dry etching method in which a connecting hole is buried with good flatness by etching back a blanket CVD tungsten layer. CONSTITUTION:A high-melting-point metal layer 5 is formed, by a blanket CVD operation, on the whole surface of a substrate including a connecting hole 6, and it is etched back by carbonyl fluoride (COF2) gas. Carbonyl sulfide (COS) may be used. An etching operation in an ion mode by CO<+> is used jointly. Thereby, it is possible to prevent a microloading effect on the basis of excessive F radicals, and an etching-back operation without abnormal corrosion can be achieved. In addition, by utilizing the concurrent reaction of the deposition of sulfur with an etching operation, an etched-back surface whose smoothness is high is obtained. When an F-based gas is added to the above gas and a two-stage etching operation is executed by controlling a mixing ratio, a high- speed etching-back operation can be performed. Thanks to these effects, it is possible to realize a multilayer interconnection structure by a high-reliability contact plug.

Title: Reproducing device of 2-system 4-channel sound pcm signal
Inventor: SASAKI KAZUJI
IPC: H03M1/66
Filed: 1985-01-24
Abstract: PURPOSE:To prevent a phase shift between channels L and R of a stereophonic signal by changing data arrangement to two systems of sound PCM signals so that the two channels in each system are in the parallel and in-phase (same time) relation and using two D/A converting means for obtaining a couple of analog outputs by each time division operation to obtain a 4-channel voice output. CONSTITUTION:Serial data of a TV sound are separated into L, R, one of them (L channel) is delayed by 16 bits to obtain L, R simultaneous data. Similarly, a changeover switch 2a and a 16-bit delay circuit 4 form independent audio data ADD as simultaneous data where the channel is separated into an (a) channel (L) and a (b) channel (R). Then one of the two systems, e.g., the independent sound channels (a, b) are delayed by 16 bits each by delay circuits 5, 6, and then 4-channel data is recombined into 2 systems by changeover switches 7a, 7b. Each of the 2-system data combined is converted into an analog signal by D/A converters 8, 9 and the L, R signals of the TV voice are obtained from the converters 8, 9 and no phase shift is caused.
