IPC: A23L17/60
Filed: 1984-03-29
Abstract: PURPOSE:Carbon dioxide is brought into contact with algae under supercritical conditions to extract lipids containing carotinoids such as beta-carotin in such a state as chlorophyll is selectively excluded to enable the extraction of lipids free from chlorophyll. CONSTITUTION:Carbon dioxide is used as an extractant and pressurized with compressor 3, heated with heat-exchanging type heater 4 to prepare carbon dioxide gas under supercritical conditions (over 75.2kg/cm<2> of the critical pressure, over 31.1 deg.C of the critical point) and the gas is fed into the extraction tank 2.

IPC: G01M99/00
Filed: 1980-05-14
Abstract: PURPOSE:To obtain the pulses synchronized to the revolutions of an AC generator for diagnosis without stopping of the rotary machine by a means of generating pulses at the same phase point of source voltage from a commerical power source. CONSTITUTION:The AC voltage 4 obtained from a commercial power source in a power station is inputted to a halfwave rectifier circuit 1 in order to obtain one pulse per cycle. Next, the voltage 5 obtained in the circuit 1 is inputted to a comparator circuit. This yields such the voltage signal in which about half period out of one cycle wherein it is the voltage determined by a circuit constant below certain threshold value voltage Vs and is zero output voltage above the threshold value voltage Vs is of a high level and the other half period is of a low level. In this way, the pulses synchronized with the revolutions are obtained easily from the AC generator in a state of parallel operation with the commerical power source.

Title: Stove for waste tire
Inventor: SAITO GENJI
IPC: F24C1/00
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To eliminate public trash contamination by waste tires by a method wherein a combustion starts from the uppermost waste tire being housed in a combustion chamber by being stacked, and the combustion is transferred to tires at lower positions in order, and an incomplete combustion gas which is a generation element of smoke at the time of combustion, is burnt in a secondary combustion cylinder, and discharged to the outside. SOLUTION: Waste tires T in a combustion chamber 11 start burning from the uppermost tire T in order. By this combustion, smoke (almost all of it is an incomplete combustion gas) generates, but this smoke gas is joined with air from an air ascending cylinder 2, and is introduced into a secondary combustion cylinder 32 by detouring a detour leading path 43 as shown by arrow 44, and the incomplete combustion gas in the smoke is secondarily burnt by the combustion heat of the tire T, and is discharged to the outside from an air outlet 35 at the upper end through a chimney 36. After the uppermost tire T is burnt, the combustion is transferred to the tire T at the next position, and the tire T starts burning. Thus, the combustion is performed by transferring in order from the uppermost tire T to the tires at lower positions, and by the combustion heat, the surrounding is heated.

Abstract: PURPOSE:To produce a calcined high-purity and high-density alumina sheet having high smoothness by adding a specific amount of alpha-alumina powder which is hexagonal platy crystals as a seed powder to an alumina sol, forming the resultant mixture into a green sheet and calcining the formed green sheet. CONSTITUTION:alpha-Alumina powder which is hexagonal platy crystals in an amount of at least 0.5wt.% based on 100wt.% expressed in terms of alumina weight as seed powder is added to an alumina sol to prepare a slurry. The above-mentioned alpha-alumina powder which is the hexagonal platy crystals can be produced by adding 0.5-1.0wt.% calcium salt to 100wt.% NaOH solution at a high temperature by the Bayer process. The resultant slurry is then formed into a film and dried to form a green sheet. The forming is carried out by a doctor blade method, etc., and the crystal surface of the aforementioned hexagonal platy crystals is oriented parallel to the sheet surface. The green sheet is subsequently calcined. In the above-mentioned calcining, the green sheet is shrunk and calcined in a prescribed direction without causing deforming, cracking, warping, holes, etc., to afford the calcined high-purity and high-density alumina sheet having a prescribed shape.

Title: Silver-oxide battery
Inventor: INADA KUNIAKI
IPC: H01M4/54
Filed: 1980-05-16
Abstract: PURPOSE:To prevent any damage to the separator of a silver-oxide battery, and increase the discharge capacity of the battery by forming a given manganese dioxide layer containing metal silver between the separator and a silver-oxide positive electrode containing a given amount of manganese dioxide. CONSTITUTION:A manganese dioxide layer 4 which contains metal silver powder and has a larger porosity than a molded silver-oxide positive electrode 2 containing 5-50wt% of manganese dioxide, is formed between a separator 3 and the molded body 2. After that, an electrolyte holding material 5 and a gel-like negative electrode 6 made of zinc are placed over the separator 3, thereby a battery being constituted. Owing to the above constitution, as the discharge of the battery proceeds,  the volume expansion of the molded body 2 which is due to the expansion of the  manganese dioxide is compensated and prevented by the volume reduction of the  silver oxide, and the deterioration of the separator 3 is prevented by the decrease in  the oxidizing ability of the molded body 2. Besides, the layer 4 facilitates the reaction inside the body 2 during the initial and the middle stage of the discharge, increase the utilization rate of the active material during the last stage of the discharge, and prevents metal silver and silver ions from shifting toward the negative electrode 6. Consequently, the discharge capacity of the battery is increased.
