Title: Manufacture of electrode catalyst
Inventor: YAMAZOE NOBORU
IPC: H01M4/88
Filed: 1998-08-20
Abstract: PROBLEM TO BE SOLVED: To improve the characteristics as a gas diffusion electrode by dispersing a carbon particle in a reverse micelle solution formed by mixing at least one aqueous metal salt solution to which a surfactant is dissolved in an organic solvent and calcinating it at a non-oxidation atmosphere after an electrode catalyst precursor is carried on the carbon particle to form an electrode catalyst. SOLUTION: A surfactant is added to an organic solvent such as cyclohexane and further, an aqueous solution of the mixture of a metal salt of a material for an electrode catalyst substance is added thereto, followed by stirring the mixture to prepare a reverse micelle solution (A). Similarly, a reverse micelle solution (B) is prepared in an organic solvent such as cyclohexane to which the surfactant is mixed. Next, when the reverse micelle solution (B) is added to the reverse micelle solution (A) and the mixture is stirred, a suspension of a mixed hydroxide of a metal is formed in the reverse micelle. After the suspension is aged, a precipitate is separated by a method such as a centrifugation, a filtration and a washing and is washed and then, after drying, the precipitate is made to a fine particle to prepare a precursor of the electrode catalyst substance.

Title: Developing device
Inventor: KASHIWAGI HIROMI
IPC: G03G15/09
Filed: 1988-09-20
Abstract: PURPOSE:To keep the concentration of toner in developer held on a developing roll at an optimum value by supplying the magnetic toner in a developer tank on the developing roll after it is adjusted to be a certain quantity with the aid of plural regulating members. CONSTITUTION:The magnetic toner is attracted to the outside of a permanent magnet 13 constituting a supply paddle 12. Then, when the magnetic toner is passed through the lower part of the regulating member 17, the layer thickness thereof is regulated to be (delta3) and the excessive magnetic toner is dropped in the developer tank 2. Next, since the size of a supply port 16 is set to be a gap (delta2) by the free edge 11d of a supporting plate 11 and the regulating member 15, the magnetic toner is supplied to a magnetic carrier housing area 11e with the prescribed thickness (delta2). Besides, the gap between the regulating member 14 and the surface of the developing roll 4 is set to be a gap (delta1) and the developer more than it is needed is prevented from being conveyed. Thus, the concentration of the magnetic toner in the developer can be easily and rapidly controlled or adjusted.

Title: Serial resonance type converter
Inventor: KIKUCHI YOSHIHIKO
IPC: H02M3/335
Filed: 1989-09-13
Abstract: PURPOSE:To obtain stability of control by driving only once a main switching element from one zero-cross to next zero-cross of a current in a parallel resonance circuit. CONSTITUTION:When the output of a converter is abruptly decreased and the frequency of an oscillator 3 is reduced, the output of a monostable multivibrator 15 attains a low level to trigger a monostable multivibrator 17. The output of the multivibrator 17 attains a high level to lower the output of the oscillator 3 during the period. Main switching transistors Q1, Q2 supply currents to a serial resonance circuit by a monostable multivibrator 4, a flip-flop 5 and AND gates 6, 7. Accordingly, the operating frequency of a converter can be held at the resonance frequency or more of a parallel resonance circuit by the setting time T1 of the multivibrator 15. The converter prevents control disable due to an abrupt drop of the impedance of the parallel resonance circuit to obtain stability of the control.

Title: High-speed character judging system in picture processing
Inventor: YAGI SHUICHI
IPC: H04N1/40
Filed: 1994-09-30
Abstract: PURPOSE: To enable shortening the picture processing time of, especially, a full-screen character picture when the picture processing such as the magnification/reduction, etc., of the picture is required by executing a rough judgement processing to know whether the full-screen character picture or not before executing minute area judgement. CONSTITUTION: When the full-screen character picture requiring the picture processing of magnification/reduction, etc., is inputted to an input picture 1, the input picture 1 is directly transmitted to a character processing 5 so as to be processed without passing through area judgement 3 which judges the character area and the photograph area of the input picture after passing through a full-screen character picture judging processing 2 which judges whether it is the full-screen character picture or not and a required output picture is obtained. Here, the processing time of the full-screen character picture judgement processing 2 is set shorter than the processing time of are judgement 3. Thus, the processing time can be shortened in comparison with the conventional processing passing-through judgement 3 when the input picture is the full-screen character picture.  When the picture with the photograph area is inputted to the input picture 1, the processing is executed by a route indicated by a dotted line arrow.

Title: Roll for giving difference of tension to metallic strip
Inventor: MIDORIKAWA SATORU
IPC: B21B39/00
Filed: 1989-09-14
Abstract: PURPOSE:To improve wear resistance of roll and to prevent sticking of foreign matters such as iron powder by dulling the surface of bridle roll and the like on which hot-melt-spray-coating of a composite material or a ceramic is performed and buffing both end parts. CONSTITUTION:After hot-melt-spray-coating of the composite material or the ceramic is performed on the dulled surface of a roll with body length L, both end parts of the roll 1 including the parts where the edge parts of the metallic strip are brought into passing contact, i.e. the surface from each end of the roll to 3L/10 is buffed. Therefore, because the surface of the middle part of roll without buffing has peculiar ruggedness of hot-melt-spray-coating, force for gripping the metallic strip is sufficiently obtained. And, because both end parts where are buffed are almost reduced with small and sharp ruggedness, it is difficult for metallic powder itself to be stuck. Then, because scabs on the edge parts of strip aren't shaved off with this ruggedness, the generation of metallic powder itself is remarkably decreased.
