Title: Corrosion inhibitory composition for organic acid pickling
Inventor: FUJIWARA KAZUYUKI
IPC: C23F11/10
Filed: 1994-06-29
Abstract: PURPOSE:To obtain an corrosion-inhibitory composition which effectively inhibits metal corrosion from occurring at the time of performing acid washing and causes no secondary corrosion even if the composition remains on the washed metal after the acid washing by blending a specific alkynyl alcohol and a specific amine together in a specified ratio. CONSTITUTION:This composition contains an alkynyl alcohol and an amine in a ratio by weight of the former to the latter of 9:1 to 1:9 and effectively inhibits the attack against metal, in particular iron, of an organic acid pickling solution for removing scale, rust, etc., on the surface of the metal. As the alkynyl alcohol, at least one compound represented by formulas I to III (wherein: each of R1, R2 and R3 is H or an alkyl group; and each of (m), (n), (k), (i) and (l) is 0 or 1 to 10) is used. As the amine, at least one compound represented by formulas IV and V (wherein each of R6, R7 and R8 is H or an alkyl, an aryl, benzyl, a heterocyclic or hydroxyl group) is used. The adequate amount to be used of the composition is about 0.1 to 2.0wt.% to the amount of the organic acid in the washing solution.

Title: Method for reducing blocking arc fact
Inventor: UIIRANTO YASU
IPC: H04N19/152
Filed: 1989-06-09
Abstract: PURPOSE: To improve the quality of images which are transmitted at a low data transfer rate by controlling the block filter function to decrease the blocking artifacts at the output terminal of a decoder. CONSTITUTION: The frequency parameter corresponding to every block via a coder functions to control the block filtering at the output terminal of the decoder, i.e., after a DPCM loop. In a scene encoding operation including the DCT(discrete cosine transformation), every image is divided into many square blocks which are contiguous to each other. The DCT and the inverse DCT which are carried out during the processing of images are applied to every block. Then the number of coefficients to be transmitted is limited in the DCT range of a single block, that is, the limitation of frequency related to the block contents is carried out, so that the bit transmission speed is kept at a limited level for the coder of a low transfer rate.

Title: Image information registration device
Inventor: KAGAYA MAKOTO
IPC: G06T1/00
Filed: 1988-06-15
Abstract: PURPOSE:To shorten the time required to register an image and to improve the use efficiency of the device by performing input operation for image information and output operation to a long-period recording device separately in parallel. CONSTITUTION:The image information which is inputted from an image scanner 8 is stored in a file 9 through an input function 4 or re-input function 6 and displayed on a CRT 1 through a confirming function 6 and when the input is in failure, the information is inputted again by using the re-input function 6 and the image in the file 9 which is already confirmed is stored by an output function 7 on an optical disk device 10. Thus, the input functions 4 and 6 for inputting data and the output function 7 for sending data out to the long-period recording device 10 operate independently of one another. Consequently, the time required to register one image is shortened and the use efficiency of the device is improved.

Title: Beam alignment correcting method for television camera
Inventor: AOKI AKIRA
IPC: H04N9/09
Filed: 1981-09-24
Abstract: PURPOSE:To improve the detection accuracy, by including a center position correcting control in a beam alignment correcting control procedure and controlling the correction while preventing shift to a reference signal. CONSTITUTION:In an automatic beam alignment correction with a microprocessor 20, the center position shift of a red channel to a green (or blue) channel, is detected at a center position shift detecting circuit 19 and the microprocessor 20 discriminates whether or not the center position is shifted to a degree out of the detecting range. If the position is shifted, the center position is matched to a reference signal via a control circuit 21. Next, the alignment shift detection to the red channel is done to correct the alignment of red channel. Further, the center position matching control and the alignment correcton are repeated and the correction is done until the mis-alignment reaches a set value or below.

Title: Ion descaling method of metal wire material
Inventor: AKIBA TOYONORI
IPC: C21D1/82
Filed: 1978-12-05
Abstract: PURPOSE:To perform descaling readily without accompanying pollution such as waste of acid solution by passing the high-temperature wire material out from the heating furnace or lead bath cell in the wire material production line through the hermetic pressure reducing device provided immediately therebehind and causing glow discharging. CONSTITUTION:The wire material having been deposited with scale is beforehand passed through a heating furnace 9 or further through a lead bath cell 10, whereby it is heated to 550 deg.C or more. This wire material is passed through the inside of a hermetic pressure reducing device 1 of a reducing gas atmosphere such as of hydrogen of about 10 Torr. Glow discharge is caused between the anode in this device and the wire material as cathode, whereby the scale is reduced and removed. Thereafter, the wire material is passed through the lead bath cell 10 or directly through a lubrication treating cell 11 by phosphate film or the like after which it is drawn to the wire material of the target diameter with a wire drawing machine 12. Since no acid solutions are used for descaling, no pollution is accompanied and since the wire material is beforehand preheated to the temperature necessary for descaling reaction prior to descaling, the electric power for descaling can be less.
