Title: Method for purifying waste containing gallium and arsenic
Inventor: OKUYAMA YUKIO
IPC: C02F1/42
Filed: 1988-03-30
Abstract: PURPOSE:To reduce the amts. of As and Ga in waste water to traces by simple operation by subjecting the waste water adjusted to 3-5pH to solid-liq. separation, adding a ferric salt to the separated liq., adjusting the liq. to 6-8pH and carrying out solid-liq. separation. CONSTITUTION:Waste water contg. Ga and As is adjusted to 3-5pH and subjected to solid-liq. separation. By this operation, about >=70% of the As is removed because dissolved metals such as Ga in the waste water are converted into hydroxides and these hydroxides act as a flocculant to coprecipitate As. The ferric salt is added to the separated liq. and this liq. is well stirred and adjusted to 6-8pH by adding an alkali agent such as NaOH. The ferric salt forms ferric hydroxide and this hydroxide acts as the flocculant to coprecipitate As. By separating the formed precipitate, the concn. of As can be reduced to a regulated value or below.

Title: Production of aromatic carboxylic acid
Inventor: TORIGATA HAJIME
IPC: C07C63/00
Filed: 1981-05-21
Abstract: PURPOSE: When an aromatic compound bearing methyl groups is catalytically oxidized into the titled compound, acetic acid which contains a specific amount of water is used as a solvent and the above aromatic compound is added to the distillate mix of water and acetic acid originating from the reaction mixture, then concentration is conducted again to separate the water formed as a by- product advantageously.  
     CONSTITUTION: An aromatic compound having at least one of methyl groups is oxidized with a gas containing molecular oxygen in the presence of a heavy metal catalyst in a solvent of acetic acid containing 5W25wt% water. Then, the distillate mix that is mainly composed of water and acetic acid orginating from the reaction mixture is combined with the aromatic compound newly fed and they are subjected to concentration to distil off almost the same amount of water as that of the water formed in the oxidation and recover the remaining containing acetic acid. The remaining is circulated to the above oxidation stage, whereby the water formed in the oxidation is separated from the acetic acid solvent without precise rectification operations and the objective aromatic carboxylic acid is produced economically.

Title: Zinc alkaline battery
Inventor: TAKADA KANJI
IPC: H01M4/42
Filed: 1987-03-31
Abstract: PURPOSE:To secure corrosion proof characteristics of a negative electrode in the state where amalgamating rate is repressed as much as possible by using a copolymer of specified oxyethylene and oxypropylene as an anticorrosive for a negative electrode active material. CONSTITUTION:A copolymer of oxyethylene and oxypropylene as expressed in a formula 1 is used as an anticorrosive which represses the corrosion of a negative electrode. The methods of application of the anticorrosive are shown below: addition of it into an electrolytic solution, impregnation of it into both or either of a separator and a member holding the solution, or application of it on the surface of a negative electrode active material. In the case of the anticorrosive, the values of a, b, c shall satisfy a formula 2 and the total molecular weight shall be in the range of 818 to 14088. To realize a sharp cutdown in amalgamating rate the combined use of anticorrosive zinc alloy and this anticorrosive is effective. For example when a zinc alloy containing indium and lead or a zinc alloy containing gallium is used jointly with this anticorrosive even at an amalgamating rate of 0.2 %, a cell with a negative electrode having enough anticorrosive characteristics can be obtained.

Title: Picture scan reader/recorder
Inventor: YAZAWA HIROMI
IPC: H04N1/04
Filed: 1986-04-04
Abstract: PURPOSE:To always record a picture having 2 different screen angles on a film with no positional deviation by scanning the 1st light beam in the main scanning direction to read the picture information on an original document, processing the obtained picture signals to modulate the 2nd light beam for picture recording and projecting the modulated beam on a photosensitive material as dot signals. CONSTITUTION:The laser beam L is secanned over a film F through a gap part formed between nip rollers 88 and 90. The end of the 1st picture recording is detected after the continuous scan of the light L and when a photodetecting means 41 reads the bar code sattached to a mobile plate 200, for example. Then a laser beam source 52 is driven again at an angle deflected by 30 deg. from the screen angle at which the 1st picture is carried out. Thus the 2nd picture scan is started. In other words, a motor 84 is driven toward an arrow head C and the rollers 88 and 90 are pressed against a rotary drum 82 for feed of the film F. Thus the picture recording is carried out.

IPC: B41F17/14
Filed: 1993-04-05
Abstract: PURPOSE:To simplify the production process of a black matrix without decreasing flatness of the surface of the produced color filter by forming both of the picture element part and the black matrix part of the color filter with one-color film in a manner that the film thickness in the black matrix part is made thinner than in the picture element part. CONSTITUTION:A tool 5 is formed by etching a copper plate as the base body 1 in an acid soln. First, the surface of the copper plate is etched twice each to form 3mum depth and to obtain 6mum depth of the picture element part by using a patterned mask. Then the picture element part and the black matrix part are etched simultaneously with a mask to 3mum depth. Thus, for example, picture element grooves 2 of 9mum depth and black matrix grooves 3 of 3mum depth are formed. By using this tool 5, color films of R, G, B are laminated on the black matrix part as well as the picture element part is formed when the color filter is produced by printing, so that the black matrix of enough light shielding property can be formed.

Title: Physically critical state detecting system for railway
Inventor: OKUYA TAMIO
IPC: B61L23/00
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To provide an inclination sensor capable of generating a warning signal by constantly monitoring the presence or absence of a critical state of a railway structure limit without depending on visibility and by promptly and accurately grasping the presence of critical state. SOLUTION: A plurality of detectors 1 consist of each detecting column and an clinometer mounted in the detecting column. The detectors are vertically installed generally along a railway line beyond railway structure limit, near the railway line. Each clinometer produces an electrical signal corresponding to an inclined angle to the vertical direction. An A/D converter 2 directly samples analog voltage signals produced from the detectors 1 at previously established predetermined intervals to convert into detected data consisting of digital signals. An arithmetic processor collects the discrete detected data from the detectors 4 and discriminates the critical state based on comparison of the detected data with a predetermined threshold value to generate a warning signal.  The warning signal generated and produced in and from the arithmetic processor flashes a specific signal light emitter installed at the wayside.

Abstract: PURPOSE:To obtain a telephone set with excellence in a sense of beauty by covering a front side of a receiver mount part with a cover whose size covers up to a front side of a lock piece so as to reduce the number of components without need of so high precision in dimensions and solving the problem of the design. CONSTITUTION:When the telephone set is used for a wall mount telephone set, a lock piece 40 is fitted to a recessed part 14 of a receiver mount 13 of a main body 12 and the receiver 10 is engaged with the lock piece 40 to mount the telephone set. Then the size of a label display section 42 and a transparent cover 44 is selected to be a size to cover part or all of a font side (toward the receiver) of the lock piece 40 so that the lock piece 40 is not entirely observed from the front side (receiver side) or only a long side 36 of the lock piece 40 is observed. Since falling-off of the lock piece 40 is prevented by the cover 44, the mount of the telephone set is enough to fit the lock piece 40 to the recessed part 12 loosely without provision of a projection or a hole. Since a gap 32 for removing the lock piece is hidden by the cover 44 or the display section 42, any special component to conceal the gap is not required.
