Title: Removal of ammonia and nitrate radical from cobalt compound
Inventor: IMAMURA MASAKI
IPC: C22B23/02
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To make ammonia and nitrate radical effectively removable to low concentrations with a small energy consumption, by baking a cobalt compound containing ammonia and nitrate radical in the inert gas atmosphere at a specific temperature. SOLUTION: A cobalt compound containing ammonia and nitrate radical obtained by ammonia leaching method is backed in an inert gas atmosphere of nitrogen, argon, helium, etc., at 300-500 deg.C, preferably 300-400 deg.C. Since the removal of nitrate radical is changed by oxygen concentration in the inert gas and removal efficiency is reduced even in slight existence of oxygen, an inert gas as pure as possible is preferable. Preferably the removed ammonia and nitrate are taken away from the spot by the inert gas flow. Consequently excessive ammonia to be reacted with nitrate radical is vaporized without being oxidized and the concentrations of ammonia and nitrate radical can be reduced to <=0.01 wt.%.

Title: Digital communication circuit and switching method of voltage level
Inventor: RICHIYAADO ERU UIIRAA
IPC: H04L25/02
Filed: 1990-04-06
Abstract: PURPOSE: To increase noise tolerance by placing a signal current source in not a driver, but a receiver and using a constant current source as its current source. CONSTITUTION: A driver chip 40 has only one switching transistor(TR) 44 and a receiver chip 42 has a constant current source 46 which is so connected that the current from a power source surface 48 is inputted and supplied to a signal line 50 at a certain rate. For example, when an output TR 44 is ON, the current of a signal source flows to the driver chip 40 through a signal line 50 to make a terminating resistor 56 of the receiver chip 42 to be in a state of short-circuit and to make a logical signal value on the signal line 50 low. Consequently, since a threshold level of the logical signal is determined only by the operation parameter of the receiver chip 42, noise tolerance of the driver-receiver pair becomes large.

Title: Magneto-optical recording medium
Inventor: TAKANO SHINICHI
IPC: G11B11/10
Filed: 1987-04-15
Abstract: PURPOSE:To prevent deterioration of a magneto-optical recording film by oxidation or nitriding even when a dielectric film consisting of an oxide or nitride is provided by interposing a shielding film which shields oxygen or nitrogen between the magneto-optical recording film and the dielectric film. CONSTITUTION:The shielding film which shields the oxygen or nitrogen is interposed between the magneto-optical recording film and the above-mentioned dielectric film. The oxidation or nitriding of the magneto-optical recording film is surely prevented by the shielding film which shields the oxygen or nitrogen even if the oxygen or nitrogen liberates from the dielectric film if the nitrogen shielding film is interposed between the surface of the magneto-optical recording film and the dielectric film. Degradation in the coercive force and CN of the magneto-optical recording film is thereby averted.

Abstract: PURPOSE:To facilitate the control of the density and MW distribution of a polymer, by effecting the polymerization in multistage polymerization tanks until the ratio of the intrinsic viscosity of the polymer formed in the last stage of the polymerization tanks to that of the polymer formed in the first stage falls within a specified range. CONSTITUTION:A polymerization reaction is effected in the first stage continuous polymerization tank A by continuously feeding thereto a solvent from a pipe 4 and at the same time continuously feeding thereto ethylene, hydrogen, and 1- butene from pipes 1, 2, and 3, respectively. The polymer is discharged through a pipe 5 and sent to a phase separator B where the formed solution is separated into phases. The thick liquid phase containing most of the ethylene copolymer is transferred through a pipe 7 to the second stage continuous polymerization tank C, and polymerized. The intrinsic viscosity of a sample of the polymer formed in the tank A [eta<1>] is 3.04, and that of a sample of the polymer formed in the tank C [eta<2>] is 1.89 and, therefore, [eta<1>]/[eta<2>] in this case is 1.6. The polymerization is continued until this ratio falls within the range of 1.1-4.

Filed: 1994-04-06
Abstract: PURPOSE:To simplify the constitution by outputting a mute signal till charging of a capacitor C, which is connected to transistors TRs A and B which are made conductive for the high level and the low level of an input signal respectively, due to conduction of the TR A and till discharging of the capacitor C due to conduction of the TR B. CONSTITUTION:When a voltage signal Hi is inputted, a TR Q1 is turned on with the signal Hi as the base current to output the mute signal, and a capacitor C1 is charged through a resistance R1. When the capacitor C1 is charged after a prescribed period, the TR Q1 is turned off not to output the mute signal because the base current doesn't flow. When a voltage signal Lo is inputted, a TR Q2 has the base set to the GND level by a resistance R2 and is turned on by the electric charge charged in the capacitor C1. Then, the charged electric charge of the capacitor C1 is outputted as the mute signal from the TR Q2, and the TR Q2 is turned off after a prescribed period by discharging not to output the mute signal.

Title: Insulation failure detecting method of power cable
Inventor: FURUYAMA KENJI
IPC: G01R31/02
Filed: 1981-06-17
Abstract: PURPOSE:To detect insulation failure of a power cable being in a hot-line state, with a high S/N ratio, by fetching a corona pulse current flowing to a ground wire by a transformer, removing an external noise by a BPF, and also using an optical fiber for transmitting a signal to an abnormal state indicator. CONSTITUTION:When an insulator of a power cable becomes faulty, a corona pulse current flowing to a ground wire 2 generates a secondary current in a secondary side coil 3b of a transformer 3. When this secondary current passes through a BPF 4 having a band characteristic of 20-100KHz, a corona pulse of a wide band is selected, and it becomes a specific frequency by which a noise of commercial frequency, a noise radio frequency, etc. are small. The corona pulse of this specific frequency is rectified by a rectifying circuit 5 which has bridge-coupled diodes 5a-5d, and drives a light emission diode 6. An optical output from this light emission diode 6 is transmitted by an optical fiber 7, reaches a photodetector 8 installed at a remote place, is converted to an electric signal, and is displayed on a abnormal state indicator 9.
