Title: Oxidation-resistant fat or oil powder and its preparation
Inventor: HASEGAWA NOBUHIRO
IPC: C09K15/34
Filed: 1993-02-19
Abstract: PURPOSE:To obtain a fat and oil powder of an improved oxidation resistance by mixing a fat or oil containing higher unsaturated fatty acids with an ethanolic aqueous solution of zein, an emulsifier, a higher fatty acid, a corn gluten meal extract, vitamin C and porous starch grains. CONSTITUTION:Corn gluten meal is dried to a water content of 1% or below and defatted with e.g. n-hexane. The defatted corn gluten meal is mixed with an ethanolic aqueous solution, and the resulting mixture is heated, kept in the heated state, then left to cool and subjected to solid/liquid separation to prepare an ethanolic aqueous solution of a zein/ethanol/water ratio of 50/(50-90)/10. The n-hexane is distilled off from the n-hexane extract to obtain a solvent extract (GM oil) of corn gluten meal. A fat or oil containing highly unsaturated fatty acids such as EPA and DHA is mixed with a specified amount of an emulsifier such as sugar ester, a specified amount of at least one member selected from between a higher fatty acid and GM oil, a specified amount of vitamin C and a specified amount of starch grains made porous by partially decomposing them with a raw starch decomposition enzyme to form an emulsion, and this emulsion is spray-dried to obtain an oxidation-resistant fat or oil powder.

Title: Low-oxygen air generator
Inventor: SUZUKI JIRO
IPC: A01F25/00
Filed: 1987-03-09
Abstract: PURPOSE:To prevent the temperature during low oxygen combustion from lowering, by recovering more heat than that radiated from a purifying cylinder from exhaust gas by an air preheater by keeping expansions of two cylinders balanced by designing the air preheater longer than the purifying cylinder, because the purifying cylinder is expanded downward by heat starting from the upper part of a combustion cylinder, while the air preheater is expanded upward by heat starting from the lower part of a purifying cylinder. CONSTITUTION:An exhaust gas generated in a combustion cylinder 1 is purified by an ash- treating filter 16 and a CO purifying catalyst 17 in a purifying cylinder 14, flowing into an air preheater 18, where it gives heat to combustion air, flowing into a cooling unit 19 at the top of a preheater, where it is cooled down to the atmospheric temperature. The exhaust gas flows into a scrubber 20 which is filled with a substance which adsorbs carbon dioxide, and then is fed into a refrigerator 9. The combustion air is circulated through a combustion part and the refrigerator 9 in order to make the atmosphere in the refrigerator 9 of low oxygen and high carbon dioxide concentration that is suitable to store vegetable and fruit. The purifying cylinder 14 is expanded downward by heat starting from an exhaust pipe 15, so that the upward expansion by heat of an air preheater 18 is cancelled, and excessive deforming stress is not produced between the air preheater 18 and the cooling unit 19. Accordingly the air preheater which has necessary and enough capacity can be mounted on an equipment in order to raise the temperature during combustion.

Title: Refining method for aluminum by reduction
Inventor: KUWABARA KANEYUKI
IPC: C22B1/244
Filed: 1980-04-22
Abstract: PURPOSE: To advantageously recover refined aluminum which is rather volatile by a method wherein briquets prepared from a mixture of ore and coal powders are coked, the coked briquets are refined by reduction, then the resultant alloy is absorbed in molten lead and the lead layer is separated from the alloy by cooling.  
     CONSTITUTION: A kneaded mixture of the ore and coal powders is fed to a briquetting machine 3 to produce the briquets, which are charged into a carbonizing machine 6 and a nonoxidizing gas is passed through the machine 6 to produce porous alumina-based coked briquets. The coked briquets are charged into a blast furnace 10 and are heated to a temperature of not lower than 2,000°C, whereby the alumina and silica contained in the ore are completely reduced to form an Al-Si alloy. In this case, molten lead is injected into the furnace 10 through a tuyere 13 so that the dropping alloy is absorbed into the molten lead. The lead and the alloy collected in a basin 20 are transferred into a retaining furnace 15, where they are separated from each other as layers by cooling. The alloy pumped up from the furnace 15 is fed to a deleading furnace 18, where a minute amount of residual lead is removed and then aluminum and silicon are separated from each other.

Title: Variable resistor
Inventor: YOSHIDA HIROYUKI
IPC: C08L67/02
Filed: 1995-02-17
Abstract: PURPOSE: To provide a variable resistor which provides a stable electric contact and has a low electric sliding noise and which is low cost. CONSTITUTION: A sliding resistor 2 is formed on a substrate 1 which is made of resin such as polyethylene terephthalete. A movable contact 4 linking with a movable member 3 which is made of resin such as liquid crystal polyester and which is formed above the sliding resistor 2 slides on the surface of the sliding resistor 2. Since the resin material which constitutes the movable member 3 and the resin material which constitutes the substrate 1 have the same coefficient of thermal expansion, there is only a small difference in thermal expansion and thermal contraction due to a change in temperature between the movable member 3 and the substrate 1. Therefore, such a trouble is prevented that a sliding position of the movable contact 4 deviates and causes an increase in contact resistance.

Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To realize a voltage comparison circuit which can suppress the influence of a noise mixed with an input signal and by which a change in the level of a signal can be detected with high accuracy. SOLUTION: According to the rise edge or the fall edge at the output signal of a comparator CMP1, a delay circuit DLY1 or DLY2 is operated.

Title: Electric heater device
Inventor: MORISHITA FUMIO
IPC: G05D23/24
Filed: 1987-03-11
Abstract: PURPOSE:To reduce the scale of the facilities and to simplify the constitution of an electric heater device by unifying a temperature controller containing the combination of plural positive characteristic thermistors and a switch circuit which gives instructions to these thermistors to switch temperatures. CONSTITUTION:The relays 29E-29A of a switch circuit 28 are actuated successively in the order of lower control temperatures with command signals given from a setting circuit 31 and the positive characteristic thermistors 20E-20A of a temperature controller 12 are successively actuated to perform the temperature control of a pipeline 1 before the pipeline 1 is heated up to a prescribed temperature by an electric heater 11. If the Curie point of the thermistor 20A is set at 300 deg.C, the resistance value of the thermistor 20A is reduced as long as the temperature of the pipeline 1 is kept at <=300 deg.C. As a result, the most of the power supply voltage is applied to a heating line 15 and the pipeline 1 is heated. Then the resistance value of the thermistor 20A increases suddenly when the temperature of the pipeline 1 exceeds 300 deg.C. As a result, the power supply voltage applied to the heater 11 is reduced. In such a constitution, the facilities for detection and control of temperatures can be unified.

Abstract: PURPOSE: To change over a cascade system to single system by means of a hand press, by changing over an actual flow detecting value and an output of the converter to a flow feedback signal corresponding to the amount of the detecting flows after having found a flow property of a check valve by means of a function converter.  
     CONSTITUTION: A process amount S 1  detected by a detector 2 is controlled by regulating a flow F. A primary regulator XC finds a flow set valve S 2  from the process amount S 1  and a set value S 0 , and the result is fed to a secondary regulator FC. The secondary regulator FC finds a valve operating signal S 5  from the set value S 2  and a flow detecting value SH of a high signal selector 12, and outputs the result to a valve 6. A flow signal SM from a flow detector 3 and a flow signal SV found at a control valve opening degree converter 10 are supplied to the high signal selector 12. The flow signal SM is automatically controlled by the flow signal SV since the signal SM is set at lower than an actual flow signal value in the case of the flow signal SM being lower than a given flow.
