Title: Screw compressor
Inventor: TORIGOE HIROSHI
IPC: F04C18/16
Filed: 1982-08-11
Abstract: PURPOSE:To prevent noise and vibration from being produced along with simplification of a compressor structure, reduction of the size and weight of said structure, and the improvement of its working efficiency by allowing both rotors to turn in a non-contact manner while attaching timing gears to the end surfaces of said rotors on their suction sides to permit said gears to engage with each other. CONSTITUTION:Timing gears 3a, 3b are respectively attached to the suction side end surfaces 1c, 2c of both rotors 1, 2 to permit them to engage with each other. These two rotors 1, 2 have been subjected to timing adjustment during an engaging test as an individual component, so that the both rotors 1, 2 are kept in a non-contact state where there is a gap ranging from 20 to 100mu between them. Accordingly, it is possible to prevent the rotors from producing vibration and noise, uniformalize the scatter of power caused by the scatter of said gap, and improve the compressor performance. Further, the structure of the compressor is simplified with the reduced size and weight, and timing adjustment of the both rotors may be carried out by making use of an engaging test as an individual component, so that it is possible to improve the working efficiency thereon.

Title: Method of measuring degree of separation of simple substance of mineral by using image analysis apparatus
Inventor: NAKAMURA IICHI
IPC: G01N33/24
Filed: 1988-06-07
Abstract: PURPOSE:To shorten measurement time by forming the binary images of all minerals, extracting the mineral to be measured and identifying a single particle and one of middling particles. CONSTITUTION:A sample contg. the mineral is consolidated and polished and is observed by a reflecting microscope. The binary images of the respective minerals are then formed from the image obtd. from this observation. The binary images of all the minerals are then formed into the reversal images of the matrix. The % (area) at which the respective particles in the 1st mineral occupy in the particles in the reversal images of the matrix image where the respective particles are incorporated is measured by each of the particles. The particles which are smaller in area rate than the prescribed numerical values which are previously registered are transferred and preserved as the middling particles. The similar operations are repeated with all the minerals such as the 2nd mineral, the 3rd mineral,.... The degree of sepn. of the simple substance is then calculated from the area of the certain mineral in the middling particles and the total area of the certain mineral. The measurement of the single particle of the mineral particles by using the image analysis apparatus is facilitated and the measurement time is shortened according to the above-mentioned method.

Inventor: MIO KOJI
IPC: H05B3/14
Filed: 1987-06-04
Abstract: PURPOSE:To uniformalize a distribution of temperature and to make a heating temperature adjustable freely by using specific metal oxides and synthetic resin as main ingredients so as to prepare heat-generating paste. CONSTITUTION:Metal oxides, e.g., V2O3, CrO2, ReO3, which are positive in their temperature coefficients of resistance and 5X10<3>muOMEGAcm or less in their specific resistance at a normal temperature and stable against heat, and synthetic resin e.g., Si resin, urethane resin, epoxy resin, are used as main ingredients so as to prepare conductive heat-generating paste. Since the conductive heat-generating paste obtained in this way has a self-temperature controlling function, a heater with a uniform distribution of temperature can be manufactured over a large to small heat-generating plane even if a coating film is dissimilar and uneven in its thickness. Further, temperature of this paste can be freely adjusted to be desired one in the range of about 350 deg.C to the maximum. Heaters of various shapes can be easily manufactured.

Title: Treatment of industrial waste water
Inventor: SUCHIYUWAATO TEII HERUMAN
IPC: C02F1/52
Filed: 1982-08-10
Abstract: An industrial wastewater treatment method is described whereby heavy metals dissolved in the waste. water are precipitated as a siurry which, when allowed to settle, will form a sludge containing at least 10 weight percent solids. In the method, an aqueous suspension or solution of a neutralizing agent is introduced into a first reactor. A suspension containing particles of carrier agent is also introduced into the first reactor. A portion, if not all, of the neutralizing agent is adsorbed on the surface of the particles of the carrier, which are maintained in suspension in the first reactor. The carrier, with its adsorbed neutralizing agent, is passed to a second reactor and simultaneously the contaminated industrial wastewater is added to the second reactor. The pH of the wasterwater is adjusted to a range between 8.4 and 10.6 by the neutralizing agent. Within such pH range, a substantial portion, if not all, of the heavy metals are precipitated in the form of a slurry. The mixture in the second reactor is passed to a solids separation device. The solids in the slurry settle to the bottom of the device to form a sludge which is removed therefrom. Purified water is removed as an overflow from the separation device. Optionally. a flocculant may be added to aid in settling the solids.insoluble calcium salts may also be precipitated in the second reactor. Such insoluble salts are adsorbed on the surface of the carrier and/or the heavy metal slurry particles and become part of the sludge formed in the seperation device.
