Title: Quantitative determination of chlorine contained in organic solvent
Inventor: SAKANO TETSUMASA
IPC: G01N31/22
Filed: 1983-11-02
Abstract: PURPOSE:To enable simple and quick quantitative determination of the chlorine in an org. solvent by using a specific selected reagent. CONSTITUTION:An alcohol soln. of alkaline earth metallic salt of iodine or ammonium iodide is allowed to exist and the free iodine is quantitatively determined in the case of determining quantitatively the chlorine in an org. solvent. Measurement is possible in the uniform phase of the org. solvent according to such method and therefore the corrosion of the device arises hardly and there is no need for separating the aqueous phase. Generation of scale in a flow passage is suppressed as well. The method is therefore easily adaptable to a continuous automatic analyzing method particularly in the process for producing the org. solvent. The chlorine in the org. solvent often coexists generally with hydrogen chloride, ferric chloride, etc. but even if such coexisting materials exist therein, the quantitative determination is accomplished without affecting the quantitative determination value of the chlorine.

IPC: H04N1/41
Filed: 1992-07-31
Abstract: PURPOSE:To compress the image data with high picture quality and at the fixed compression rate by selecting the reversible compression processing or the non-reversible compression processing based on the relationship between the quantity of compressed data undergone the reversible compression of a block and a prescribed quantity of data. CONSTITUTION:An image processor which processes the image data for each block is provided with a reversible compressing means 3 which reversibly compress the blocks and an ADCT compressing means 4 which non-reversibly compress the image data. Then the block undergoes the reversible compressing processing with D<=L and the non-reversible compression processing with D>L respectively (D: the compressed data quantity obtained with the reversible compression of the block; L: the prescribed data quantity). Then the result obtained by expanding the compressed data as the reversible compressed data or the result obtained by expanding the compressed data as the non-reversible compressed data is selected baded on the input information. Thus, the original image data are restored. As the result, the images produced by a computer can be reversibly compressed and the picture quality of the natural images can be improved with the non-reversible compression processing.

IPC: G11B5/127
Filed: 1985-09-19
Abstract: PURPOSE:To prevent the deformation of a gap edge part by melting glass and filling the molten glass into the space between butt surfaces near a sliding surface. CONSTITUTION:A welding glass bar 8 is set in the front gap of a core consisting of a soldered magnetic metallic Fe-Al-Si material and heat is applied in this state to the bar to melt the glass and to penetrate the molten glass in the air gap part 6. The air gap is replaced with the glass by the penetration of the molten glass and is closed if the glass having the working temp. lower by 100-200 deg.C than the silver brazing temp. is used. On the other hand, SiO2 is virtified by the penetrated glass and the boundary with the SiO2 is sometimes invisible in the case of using the SiO2 for the material of a gap spacer 5. The deformation of the gap edge is thereby prevented.

Title: Synchronizing signal discrimination circuit
Inventor: KONISHI AKIYO
IPC: H04N5/46
Filed: 1990-08-02
Abstract: PURPOSE:To accurately discriminate a binary synchronizing signal and a ternary synchronizing signal with very simple constitution by forming the discrimination circuit with a pulse generating means using a gate pulse to gate a positive pulse of the synchronizing signal and generating an output pulse having a prescribed pulse width based on the gated positive pulse and with a comparator comparing the output pulse with a reference level to obtain a synchronization discrimination output. CONSTITUTION:An input video signal (d) after pedestal clamp is compared with a lst reference level V1, resulting in obtaining a comparison output (e). In this case, since no positive pulse is in existence in a binary synchronizing signal, a comparison output for the part is not obtained. Thus, a level of the comparison output (e) gated by a gate pulse (f) is 0, then a monostable multivibrator circuit 26 is not triggered based on the output. Thus, when the binary synchronizing signal is included in the input video signal (a), the detection means is controlled so as not to be in operation and when a ternary synchronizing signal is included in the input video signal (a), the detection means is controlled to be in operation.

Title: Adsorption and separation of paraxylene using diethyltoluene desorbent
Inventor: HAAMAN EI JINEN
IPC: B01D15/04
Filed: 1989-08-08
Abstract: PURPOSE: To effectively obtain p-xylene from a mixture of xylene isomers, by adsorbing the mixture on a specific crystalline aluminosilicate as an adsorbent and separating the desired compound using diethyl toluene as an desorbent.  
     CONSTITUTION: Separation of p-xylene from the mixture of xylene isomers is effected by contacting a mixture of p-xylene and one or more other xylene isomers with an adsorbent consisting of a crystalline aluminosilicate containing a Group IA or IIA metal ion at exchangeable cationic sites, to adsorb selectively p-xylene and obtain a raffinate of weakly adsorbed other xylene isomers. Then, the p-xylene-containing adsorbent is contacted with a desorbent comprising diethyltolunene to separate p-xylene as an extract stream from the desorbent. Thus, use of the desorbent which can be readily separated from the starting mixture in the extract or raffinate by simple fractionation can separate p-xylene readily from the isomer mixtures, and diethyltoluene can be reused.

Title: Al-alloy trolley wire and preparation thereof
Inventor: TAKEDA YOSHINOBU
IPC: B22F9/08
Filed: 1983-10-31
Abstract: PURPOSE:To easily obtain an Al-alloy trolley wire excellent in anti-wear property and corrosion resistance, by molding a powder due to a quenching solidification of an Al-alloy having a predetermined amount of Fe contained therein by a hot plastic processing method. CONSTITUTION:A molten Al-alloy containing, on a wt. basis, 5-20% Si, Fe<=1% and Cu<=0.5% and comprising the remainder of Al is sprayed to form a powder with a particle size of 0.2mm. or less and, at the same time, quenched at 10<3> deg.K/ sec. By this method, a powder having a fine crystal structure is obtained. When this powder is used as a stock material and subjected to sintering molding by a hot plastic processing method to be processed into a wire material, molding can be performed easily. In this alloy, Si-particles are precipitated as a hard dispersion in order to develop anti-wear property. As other alloying elements, Cu is suppressed because strength is enhanced while corrosion resistance is deteriorated but the upper limit thereof is set as mentioned above from the aspect of the security of economical efficiency. Further, strength is held by the solid solution of Si and Al as well as the fine dispersion of Si-particles and flexibility is further held by the formation of a fine structure.

IPC: B23K11/06
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To maintain a superior weld quality even in the curvature part of a weld line by inclining a pair of roller electrodes so that each axial center comes close to the center of the curvature in the case where the weld line has a curve and thereby suppressing slippage of both roller electrodes or twist of a work to be welded. SOLUTION: In welding the curvature part C of a weld line L in a work W, both roller electrodes 1, 2 are tilted at an equal inclined angle so that each axial center 1a, 2a comes close to the center O of the curvature. In the case where the upper roller electrode 1 comes into contact with the work W and where the weld line L is the curvature part C with the center O, the axial center 1a of the upper roller electrode 1 and the work W are apart from each other by a small distance on the center O side of the curve, and by a large distance on the opposite side. In the curvature part C, the upper roller electrode 1 moves at a slow speed on the center O side and at a high speed on the opposite side. The upper roller electrode 1 has no tendency to expand out of the weld line L. The upper and the lower roller electrode 1, 2 pass through the curvature part C at the same speed.
