Title: Base-extractible petroleum marker
Inventor: MAIKERU JIEI HARISHII
IPC: C10M133/28
Filed: 1993-06-30
Abstract: PURPOSE: To easily and precisely distinguish the brands and the grades of petroleum products using reactive extraction system by labeling petroleum products with the new silent markers.  
     CONSTITUTION: Firstly, markers of the formula is added to petroleum products in a detectable level, usually in an amount which results a concentration of 0.25 ppm or more in the final liquid petroleum product. Subsequently, the marker of the formula is extracted by an alkaline aqueous medium (suitably, a 50/50 mixture of a 2 wt.% NaOH aqueous solution and methanol) from the same petroleum product. Finally, the color of the marker in the extract liquid is observed. As the markers, for example, there is 2,6-di-sec-butyl-4-[2',5'- dimethoxy-4'-(4'-nitrophenylazo)]phenylazophenol or the like. In the formula, W is H or O-(1-3C) alkyl, provided that at least one of W is O-(1-3C) alkyl; X, Y are each H, alkenyl or the like.

Title: Chromate treating method of galvanized steel product
Inventor: TAMURA TETSUPEI
IPC: C23C22/30
Filed: 1978-12-29
Abstract: PURPOSE:To form the film of superior corrosion resistance without hygroscopicity, peeling etc. by coating the aqueous solution composed of the specific ratios of chromic acid, chromic acid reduction product and the specific grain sizes of silica powder to a galvanized steel plate. CONSTITUTION:The aqueous solution which is composed primarily of chromic acid, chromic acid reduction product and silica powder of 30-70mmu in mean particle size and in which the ratios of these contents are such that the ratio of the chromic acid reduction product to the chromic acid is 1:0.6-1 respectively in CrO3 equivalent weight ratio and the ratio of the silica powder (SiO2 equivalent) to the total amount of the abovementioned both materials (CrO3 equivalent) is 1:0.2-20 is coated on the steel plate or the like having been coated with zinc or zinc alloy, after which the steel plate is dried without rinsing. The addition of the chromic acid reduction product increases Cr<+3> ions, increases the degree of polymerization of chromium chromate and makes the chromate film difficult to dissolve and the increase in the particle size of SiO2 improves corrosion resistance.

Title: Method and device for managing process
Inventor: KAWAI NORIYA
IPC: G06Q50/04
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To allocate schedules to workers in detail such as optimum setting for reducing a fraction defective, setting for averaging the working of plural workers and setting corresponding to worker's ability. SOLUTION: A worker allocation method is selected from a 'worker's ability priority' method, a 'worker's load average priority' method and a 'worker's minimum fraction defective priority' method in each working process and workers are allocated in accordance with the selected method. Consequently workers having high ability are allocated to a working process requiring high ability, workers having average ability are allocated to a simple working process which can be done by anyone so that the working load of respective workers is averaged, and a worker having a low fraction defective is allocated to a working process which requires that the fraction defective is not increased.

Title: High-frequency wave heating device
Inventor: KASAI ISAO
IPC: H05B6/68
Filed: 1986-07-10
Abstract: PURPOSE:To enable an automatic setting of a heating electric power, ON/OFF time of a heating operation etc. in response to a state of a food by a method wherein at least water vapor outputted from a heated item is sensed by a humidity sensor at a control part and an output of high-frequency wave is changed over in response to a sensed amount. CONSTITUTION:An instruction inputted from an automatic cooking key 2 on an operation panel 1 is read and interpreted at a control part 3. The control part 3 may start to defreeze and cook a freezed food of a heated item 12 placed within a heating chamber 10. A heating is controlled in such a way as an electricity is supplied to a magnetron of a high-frequency wave generating means 7 through a driver 4. Signals from a weight sensor 14 for use in detecting a weight of food and a humidity sensor 9 for detecting a water vapor etc. outputted from the feed pass through a sensing circuit 5 and read and interpreted by the control part 3. The control part 3 may determine a changing- over timing of an output of a high-frequency wave for heating the freezed food, determine intermittent ON/OFF time of an output of a high-frequency wave as well as a low output level so as to control an entire heating time.

Title: Wet friction material and its production
Inventor: ONO HIDEO
IPC: F16D69/02
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To produce a wet friction material capable of surely having enough porosity with high strength and further capable of suppressing the wear of itself and an opposite material. SOLUTION: A papermaking body is formed by previously carrying out papermaking of carbon fiber, impregnating a thermosetting resin (a binder) liquid such as a phenol resin with fine particles of mesophase pitch powder dispersed in the papermaking body, and heat molding the papermaking body with the impregnated resin to provide a precursor. The precursor is fired to carbonize the mesophase pitch and the thermosetting resin and to provide the objective friction material comprising a carbon fiber/carbon composite material consisting essentially of the papermaking body of the carbon fiber as the substrate and the mesophase pitch (an optical anisotropic carbon) as time matrix. Because the papermaking body of mutually interlaced carbon fibers forms a strong, homogeneous network structure as the substrate, enough porosity can be surely formed while maintaining a high strength.  As the matrix consists essentially of the carbide of mesophase pitch, high in strength but little in attacking properties, both wears of itself and the opposite material can be suppressed.

Title: Gasifier for livestock excretion
Inventor: NIWA CHIEMASA
IPC: C02F11/02
Filed: 1980-11-17
Abstract: PURPOSE: To obtain inflammable gas directly from livestock excretion containing a large amount of water, by completely burning a part of the livestock excretion in a gas-generating oven to generate inflammable gas, and utilizing the combustion heat for fermentation of livestock excretion in a fermentation chamber at the upper part of the oven.  
     CONSTITUTION: Fowl droppings having water content of 20% or so are charged through the upper part of a fermentation chamber 2 at a rate corresponding to capacity inside a gas-generating oven 1 and a trancated cone-shaped part at the lower part of the vessel 2, and filled in the oven 1 by an agitating blade 24. After the blade 24 is stopped, crude droppings having water content of 60% or so are filled up to the upper part of the vessel 2, and the vessel 2 is hermetically sealed. Therafter, the droppings are set alight at the lower opening of the oven, a blower 4 is driven, and the blade 24 is rotated by a motor 27. Consequently, the fowl droppings at the lower part of the oven 1 are completely burnt, while those at the upper part are incompletely burnt or roasted to generate inflammable gas. The inflammable gas is introduced through a communicating hole 18 into the vessel 2, and then carried through the interior of a distributor 28 and through-holes 30, so that the inflammable gas is uniformly fed into the crude droppings. Thus, the droppings are fermented, heated and dried. The resultant ashes are dropped into a rooster 8, while water content and tar content are removed from the gas having reached the upper part of the vessel 2.

Title: One-side multi-pole magnet with yoke
Inventor: NAGASHIMA TOMIO
IPC: H01F7/02
Filed: 1982-09-18
Abstract: PURPOSE:To increase effective flux on an operating magnetic pole surface by a method wherein a yoke is provided on the back side of an anisotropic magnet, which is multi-pole magnetized to the direction of easy magnetization, to avoid the generation of unnecessary flux. CONSTITUTION:A yoke is provided on the back side of an anisotropic magnet, which is multi-pole magnetized to the direction of easy magnetization, to make flux circulated easily and covers the weak point of magnetizing to the direction of difficult to magnetize. For instance, when an SmCo magnet (diameter 5mm., thickness 1.5mm., direction of thickness is the easy-to-magnetize direction) is magnetized to the slant or perpendicular direction against the pole surface, flux on the pole surface increases from 2,300G to 2,700G and flux on the back side reduces from 2,100G to 140G if the yoke is provided. With this constitution of a magnetic circuit using such single magnet and the yoke, flux on the operating magnetic pole surface can be increased and generation of unnecessary flux on the back side is avoided.
