Title: Disturbance absorbing circuit for transmission signal
Inventor: OOSAKI TAKAAKI
IPC: H04Q1/30
Filed: 1991-03-01
Abstract: PURPOSE:To absorb the disturbance of the signal by reducing the deterioration of a protective characteristic against plural signals without increasing the quantity of a hardware. CONSTITUTION:Plural pieces (each one bit) of object signals whose protection from a disturbance is desired are series signals (multiple signals) of many bits. These signals pass through a receiving circuit 10 and become parallel signals by a series-parallel converting circuit 11. OR is taken by an OR circuit 12. A continuation monitoring circuit 13 monitors whether an output signal of the OR circuit is continued by the time which is shorter than the continuation time of a fault and other significant state, but is set longer than a general disturbance time or not. At the time of exceeding the set time, the signal is outputted and a gate 15 is opened, and the signal at such a time, held in a signal extracting part 14 is outputted and displayed. The set time of the monitoring circuit 13 is set to the time corresponding to many frame periods, and even if a disturbance signal is contained in an OR output, it is annihilated within this set time, therefore, the disturbance signal is not outputted from the gate 15.

Title: Bit synchronizing circuit/method for serial communication
Inventor: KOBAYASHI NOBUYUKI
IPC: H04L7/08
Filed: 1994-03-08
Abstract: PURPOSE:To provide a bit synchronizing circuit which can surely settle the synchronization without being affected by noises by detecting whether the width of the bit pulse of preamble of the reception data is kept within the allowable pulse width set by adding a prescribed allowable error to the pulse width that is prescribed by the transfer speed of the reception data. CONSTITUTION:The settlement of synchronization is decided and a synchronization settlement signal is outputted to a clock pulse generating part CPG when the coincidence pulses sent from the pulse width detecting parts 1 and 2 are continuously counted in the prescribed frequency by a synchronization settling part SYN while the preamble of the reception data is received. The part CPG generates a reception clock pulse in the center timing of the bit pulse of a data frame of the reception data. Therefore the coincidence pulses are not continuously outputted from the parts 1 and 2 in the prescribed frequency if the reception data include the noises. Then a non-coincidence pulse signal is outputted halfway so that the influence of noises can be evaded.

Abstract: PURPOSE:To suppress the corrosion of a furnace core tube, and to obtain an optical fiber preform at a low cost, by heating a porous preform at a low temperature to effect the thermal shrinkage, and reheating to the vitrification temperature. CONSTITUTION:The porous preform 13 deposited in the reaction vessel 16 made of e.g. Pyrex glass, etc. is heated in the electric furnace 15 maintained at about 1,300 deg.C (lower than the vitrification temperature) to effect the thermal shrinkage and obtain a semitransparent preform 12. The porous preform 13 is dehydrated in the above process with chlorine gas. The semitransparent preform 12 is transferred to another electric furnace, and reheated at about 1,500 deg.C to obtain a transparent glass preform. The reheating process is carried out using a furnace core tube made of carbon in the stream of pure helium gas to minimize the corrosion of the carbon core tube. Since the pressure control in the electric furnace and the core tube is not necessary, the operation can be simplified and the yield of the optical fiber preform can be improved.

Title: Dephosphorizing method for molten iron
Inventor: ITOU YUKIYOSHI
IPC: C21C1/02
Filed: 1981-03-16
Abstract: PURPOSE:To produce molten iron of low P at a low cost by blowing a dephosphorization (de-P) agent consisting essentially of CaCO3 to the molten iron of low Si obtained by removing Si beforehand to the depth deeper to a certain extent from the surface of the molten iron. CONSTITUTION:A de-P agent consisting essentially of CaCO3 is blown together with a carrier gas to molten iron of low Si obtained by removing only the Si beforehand from the molten iron through pretreatment through an immersion lance at >=1m depth from the surface of the molten iron. An oxidizing gas is used as the carrier gas and air is economical and desirable. Then, the P in the molten iron is oxidized by CO2 which is the product of decomposition of CaCO3 and the O2 in the carrier gas to a Ca salt which is removed. Hence, the saving of the de-P agent is made possible as well.
