Title: Recovery of chlorine
Inventor: ROBINSON MICHAEL
IPC: C22B1/08
Filed: 1985-06-13
Abstract: Chlorine may be recovered from residues from the fluidised bed chlorination of iron-containing metalliferous oxidic materials, such as ilmenite, bauxite, chromite, wolframite, scheelite, tantalite or columbite, the residues containing condensed iron chloride and blow-over bed solids, by heating the residue to revolatalise the iron chloride and reacting it with oxygen. The quantity of iron chloride in the oxidic material is controlled relative to the quantity of blow-over carbon so that the quantity of carbon is sufficient on combustion to provide the required heat but is insufficient to cause undue dilution of the chlorine produced by virtue of its combustion products. Chlorine of a concentration suitable for direct recycle to a chlorination process, e.g. of 30% to 50% volume concentration is produced.

Title: Interconnecting device
Inventor: IMAI KEISUKE
IPC: H02J3/38
Filed: 1988-05-25
Abstract: PURPOSE:To realize an interconnecting circuit having high reliability and less loss by using a superconducting lead as the interconnection of a non-utility generator power source to an external power source. CONSTITUTION:A superconducting lead G and a disconnecting mechanism for opening a line when the lead G limits a current are connected in series with a line connected from a power distribution system 60 of an external power source to a non-utility load 70. The mechanism detects a current limit by a current limit detector 13 and opens a switch 10. A bypass circuit 20 is provided in parallel with the lead G and the mechanism. When a non-utility generator 80 is defective, the switch 20 is closed through a detecting mechanism 30, and the lad G is bypassed to connect the external power source 60 directly to the non-utility load. The lead G is cooled by a refrigerator 82. When an abnormal current flows to the lead G, it is quenched to disconnect the external power source system.

Title: Surface treatment of connection part of optical fiber
Inventor: MINEMATSU MASAKI
IPC: G02B6/255
Filed: 1983-07-12
Abstract: PURPOSE:To improve the strength of a connection part by using a gas flame as a heat source and interposing a heat resisting thermal diffusing plate between the gas flame and a fiber and make the control of the gas flame easy to evaporate a surface layer including minute flaws of the surface of the fiber with an easy operation. CONSTITUTION:In this method, flaws generated in surface layer parts of optical fibers 5 and 5' in a welding connection part are processed by fire polishing in case of welding connection between optical fibers. First, the welding connection part of fibers 5 and 5' is arranged in the horizontal direction above a gas burner 10 through a heat resisting thermal diffusing plate 11 and is heated by a gas flame 12 from the gas burner 10. The head of the gas flame 12 is transmitted to the diffusing plate 11 and is diffused, and local heating is not performed. Temperature distributions in fibers 5 and 5' are adjusted by changing the arrangement of the burner 10 and the diffusing plate 11 or the size of the gas flame 12, and thus, surface layer parts of fibers 5 and 5' are evaporated to eliminate flaws on surfaces.

Title: Quantization control circuit
Inventor: KITAMURA TAKUYA
IPC: H04N19/136
Filed: 1993-04-30
Abstract: PURPOSE:To prevent deterioration in the picture quality by deciding preceding quantization information based on DCT coefficient data even in the dubbing state where the preceding quantization information cannot be received. CONSTITUTION:A quantization index decided by the binary search is fed to n-sets of multipliers 42 via an absolute value processing circuit 41. A shift circuit 43 is connected to each multiplier. Each multiplier 42 and each shift circuit 43 form a quantizer, which divides respectively input coefficient data by the quantization index and quantization indices increased by 1, 2,..., +n. A fraction part being the result of the division is fed to an accumulator via an absolute value processing circuit 44. A maximum/minimum value detection selector 46 outputs a maximum value among values from the accumulator 45 and outputs of a quantization index corresponding to a minimum value among the values selectively and decides the quantization index being the output to be a preceding quantization index.

But in case chip selection signal CS is set at the 1 level through CPU1 to select IOC3 and I/O2, both writing signal WR and interruption reception signal INTA are not used and set at the 0 level. Then inverter 21, mono-multi 22 and 23, R/S latch 26 plus gate circuits 24, 25 and 27 are provided to IOC2, and the internal reset signal of IOC2 is produced at the edge where signal CS returns to 0 from 1 when both signals WR and INTA are 0. When  signal CS changes to 1 from 0, mono-multi 23 becomes effective to deliver 1 from  latch 26. While mono-multi 22 becomes effective when CS changes to 0 from 1, and  0 is secured again after delivering 1 for a fixed time. And the output of gate 27 is  used as the reset signal.
