Abstract: PURPOSE: To make possible control of the etching speed and prevent the oxidation of Al base film employing a mixed liquid of phosphoric acid and hydrofluoric acid with addition of perchloric acid in the etching of a protective film formed on the Al bonding pad of a semiconductor device.  
     CONSTITUTION: An etching liquid composed of 85wt% of phosphoric acid, 46wt% of hydrofluoric acid and 60wt% of perchloric acid varies in the etching speed with the content of fluorine. This chart shows the relationship with the etching speed (Å/min.) on the vertical axis y and the mixing ratio (% by capacity) of hydrofluoric acid with respect to the etching liquid. In the chart, at the point A, the amount of perchloric acid is 20ml, phosphoric acid 5 ml and hydrofluoric acid 0.5ml., namely, 1.9% by capacity in the content, while at the point B, it is respectively 20ml, 5ml and 1.5ml, namely 5.6% by capacity in the content. As clearly seen from this, the most desirable composition is 20ml, 5ml and 0.5W1.5ml for respective components.

Title: Tensile strength corrective controller for sheet
Inventor: TAKADA MASAHIKO
IPC: B65H23/195
Filed: 1993-06-18
Abstract: PURPOSE:To carry out stable correction of tensile strength by controlling the tensile strength of a winder so that a set sheet tensile strength is achieved by a means for controlling the rotation speed of the winder according to a winder velocity reference signal, and a means for detecting the position of a dancer roll which varies as the tensile strength of the sheet varies. CONSTITUTION:The rotation speed of a winder is controlled by a winder motor M2 according to a winder velocity reference signal via a tensile strength corrective controller 2. The position detection signal 13 of a dancer roll 3 which varies as the tensile strength of the sheet varies is amplified by a tensile strength signal amplifier 10, and the amplified tensile strength signal 4 is used to control the rotation speed of the winder via the tensile strength correction controller 2. A set level of the tensile strength of the sheet is achieved by these modes of controlling the rotation speed of the winder. The sheet can thus be wound up by stable tensile strength in a normal condition.

     CONSTITUTION: Thermo-oxide films 2 and 3 are formed on the surface and the back each of an n-type S i  substrate 1 and a p-type impurity is diffused through a window provided on the film 2 to form a p-type base region 4. Thus, a pn junction 5 is yielded between the film and the substrate. Then, a thermo-oxide film 2 a  is applied on the region 4 and with a window 6 made thereon. an n-type emitter region 7 is formed by diffusion, whereby a pn junction 8 is yielded between the substrate and the region 4. Thereafter, the substrate is entirely covered with an oxide film. At this point, first, employing SiH 4  and O 2 , an oxide film is formed by heating up to 400°C through a vapor phase growth and then, a polycrystal Si film is formed at the same temperature through a vapor phase growth. Finally, a thermo-oxide film 11 is made to grow in lamination with H 2  by heating up to about 1,000°C. In this manner, the substrate is made free from skewness.

Title: Synchronization separator circuit for composite signal
Inventor: NONAKA TADASHI
IPC: H04N5/08
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To separate a horizontal synchronizing signal stably independently of a waveform of a video signal by allowing the circuit to have a feedback loop circuit that makes a DC level of a composite signal stable. SOLUTION: A feedback loop circuit that makes a DC level of a composite signal stable controls a charging current of a charging circuit 9 by a feedback signal in response to a SYNC signal level of an output signal of an LPF 3 for a SYNC signal period of a composite signal, and controls a discharging current of the charging circuit 9 by a feedback signal in response to a pedestal level of a back porch of the output signal of the LPF 3 for other period than the SYNC signal period of the composite signal. An output signal from a voltage comparator circuit 4 switch-controls the connection between the charge/discharge circuit 9 and an input node 1a. Thus, a DC level of the composite signal is not deflected depending on a waveform of the composite signal for the video signal period and a clamp position is not fluctuated.

Title: Picture coder
Inventor: OTAKA HIDEKI
IPC: H04N19/00
Filed: 1989-06-09
Abstract: PURPOSE:To attain the processing at a low speed as to each coder by using plural coders to an HDTV signal to apply parallel processing. CONSTITUTION:In the case of an HDTV signal, an input signal is split into 4 by a 1st switch 2 and written in 1st-4th buffer memories 3-6 and read from the buffer memories 3-6 simultaneously to apply parallel processing. Since dispersion (rough and minute parts) takes place into a data by each parallel processing, random processing is applied by a shuffling device 8. After DCT operation is applied to a random processing data, variable length coding is applied to each conversion data. As to the write to the buffer memories 3-6, since the data is processed at random by shuffling at readout, there is no special restriction except the changeover of a 1st switch 2 in the unit of lines specified by the size of a block.

Title: Comparator circuit
Inventor: MASAKI SHIGERU
IPC: G01R19/165
Filed: 1986-06-26
Abstract: PURPOSE:To prevent a chattering phenomenon and to quickly return reference value to initial reference value by connecting a capacitor between an input terminal which is one side of a comparator where reference value is set and its output terminal. CONSTITUTION:When a power source input terminal 2 is connected to a high potential power source, the output of the comparator 1 produces H. And accompanied with charging of a capacitor C1 an integrated voltage which is inputted to a reverse input terminal of the comparator 1 is raised gradually, when the integrated voltage is over the referenced voltage which is set in non-reverse input terminal, the comparator 1 produces output L. On the other hand, when the output level of the comparator 1 is L, the current through a registance R1 is carried into the capacitor C2. The reference voltage set in the non-reverse input terminal of the comparator 1 drops to prevent the generation of the chattering phenomenon, and also initial reference voltage is thereby recovered accompanied with the charging of the capacitor C2 after a short time passage.
