Patent IN-2015DN00743-A (IN)
Inventor: SENYUTA ALEKSANDR SERGEEVICH
IPC: C22B3/10
Filed: 2012-07-20
Abstract: The invention relates to metallurgy in particular to acidic methods for producing alumina and can be used in the processing of low grade aluminium containing stock. The method for producing alumina comprises burning the aluminium containing stock treating the product with hydrochloric acid salting out aluminium chloride by saturating the clarified chloride solution with gaseous hydrogen chloride calcining the aluminium chloride in order to produce aluminium oxide and pyrohydrolyzing the mother liquor with the hydrogen chloride being returned to the acid treatment stage and being salted out. In order to increase the quality of the alumina and reduce energy consumption the aluminium chloride precipitated during the salting out process is treated with ammonium hydroxide the residue produced is sent for calcination and the solution of ammonium chloride is mixed with the aluminium containing stock before the latter is burned or during the burning process ammonia separated out during the burning is dissolved in water and the ammonium hydroxide produced is sent for treating the aluminium chloride. The solution of ammonium chloride can be subjected to phased concentration by evaporation with repeated use of heating steam before being mixed with the aluminium containing stock. The ammonium chloride separated out when concentrating the ammonium chloride by evaporation can be mixed with the aluminium containing stock.

Title: Method for allocating alternate sector, method for reading out data, disk drive assembly and device for reading out and writing av data
Inventor: ONO HIROYUKI
IPC: G11B20/10
Filed: 2000-01-06
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration in performance in reading the data in alternate sectors. SOLUTION: It is assumed that a write request of data (a) is made to a sector A, but since the sector A is a defective sector, the data is written into the alternate sector A' of an alternate sector region X. Next, when the write request for data (b) is made to a sector B, the alternate sector B' succeeding to the alternate sector A is subjected to reassignment. The defective sector C to which the write request for data (c) is made is similarly reassigned to the alternate sector C'. Accordingly, the continuous data (a), (b) and (c) are eventually written into the continuos sectors A', B' and C' within the same alternate sector X.

Title: Control device of variable displacement compressor
Inventor: KAWAGUCHI MASAHIRO
IPC: F04B27/18
Filed: 2000-01-07
Abstract: PROBLEM TO BE SOLVED: To provide a control device for variable displacement compressor capable of enhancing the controllability and responsiveness in the discharge displacement control of the compressor despite its simple controlling configuration. SOLUTION: The compressor is equipped with a control valve to work so that the differential pressure between two pressure monitoring points P1 and P2 set in a refrigerant circulating circuit is maintained at the specified target value (set differential pressure TPD). A sensing circuit 85 compares the temperature in the neighborhood of an evaporator 33 with the specified threshold temperature T1 or T2 and emits a signal when the larger becomes smaller than the other. In principle, an engine ECU 70 continues a processing to increase or decrease the set differential pressure TPD gradually with elapse of the time, and changing over of TPD from the incremental to decremental or vice versa is conducted when the signal is fed.

Title: Power supply and its control method
Inventor: NAGAI TAMIJI
IPC: G05F1/56
Filed: 2000-01-27
Abstract: PROBLEM TO BE SOLVED: To provide a power supply that can eliminate heat generated by a constant-voltage circuit and a constant-current circuit in a case that it supplies a direct power to load keep a superior level of safety, reduce its physical size, and operate within its operation range despite a high input voltage. SOLUTION: Direct current power is supplied from an input terminal T1. Voltage ad current supplied from the terminal T1 are sent to a voltage detector 1 and a current detector 2 respectively. The voltage detector 1 detects the input voltage that is higher than a reference voltage. When the current detector 2 detects an input current that is more than the first reference current, a signal is sent to a time constant circuit 5 and a pulse current detector 4. If the detector 4 detects the pulse current, a control circuit 7 increases impedance of a constant- voltage circuit 3. The power supply stops an output of a constant-voltage circuit 3 if an overcorrect is detected through the time constant circuit 5 and a stop circuit 6.
