Title: Multiplex channel optical fiber communication system
Inventor: ANDORIYUU AARU CHIYARAPURIBUI
IPC: H04B10/255
Filed: 1995-02-17
Abstract: PURPOSE: To increase the capacity of the system by making an interval large enough to evade the matching of the wavelength of an arbitrary 4-wave mixture product with the wavelength of arbitrary channel carrying, and reducing the limitation of 4-wave mixture. CONSTITUTION: Eight external cavity lasers represented as radiation wavelengths λ1 to λ8 are multiplexed by 4x<1> passive couplers 30 and 31 and a 2x<1> passive coupler 32 and an LiNbO3 modulator 35 generates a dummy bit stream of 10 Gb/second. A spool of 20 km introduces discrete delay to give a 3-bit shift/ channel at a speed of 10 Gb/second. After amplification by EDFA 37, those signals are sent to a variable power attenuator 36 to adjust radiation power. The attenuator 38 is used integrally with the spool 39 to provide proper insertion loss and 4-wave mixture. The signals pass through EDFA 43 next and are inputted to variable optical filters 44 and 45, EDFA 46, and a filter 47.

IPC: G05B19/02
Filed: 1995-02-17
Abstract: PURPOSE: To simplify processing by transmitting the state data of all object equipment to be sent from a transmitter to its host station in the form of state change data when the abnormality of that host station is recovered. CONSTITUTION: A transmitter 01 periodically fetches input data 1 showing the state of supervisory object equipment, and this-time value data 2 and the- last-time value data 3 are compared by a state change check means 4, defined as state change data 8 and 9, sent to duplex host stations 02-1 and 02-2 and processed by the host station on the active side corresponding to state changes. When the abnormality of the host station 02-1 is recovered, the transmitter 01 switches a changeover SW 16, the this-time value data 2 are inverted by an inverting means 6 and defined as the last time value data 3, and identification flags are added to all the state change data, which are generated by comparing these data 2 and 3, and transmitted. The host station 02-1 watches the flag and switches a changeover SW 18 and all the state change data are converted into state information 21 of all the object equipment and stored. Afterwards, ordinary state change data are received as 22 and the state information 21 is updated and processed corresponding to its state change.

Title: Plant-style electric cord cover
Inventor: YAMAYA HARUO
IPC: H02G3/02
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To make an offensive electric cord in sight nice to look at by a method wherein holes are made at equal intervals, an adhesive double coated tape is pasted on the inner side of a tube in which a tearing part is formed on the opposite side and root parts of artificial flower leaves are inserted into the holes. SOLUTION: Holes 4 which are made at equal intervals in a tube 2 are used so that root parts 7 of artificial flower leaves 6 are inserted. In addition, an adhesive double coated tape 3 is pasted on the innser side of the tube 2 on the opposite side of the holes 4 so as to cover an electric cord 1. Then, the adhesive double coated tape 3 is arranged so as to vacate only peripheral parts of the holes 4. This is intended so that the root parts 7 of the artificial flower leaves 6 do not interfere with the adhesive double coated tape 3 when the root parts are inserted into the holes 4. In addition, the root parts 7 of the artificial flower leaves 6 are made a little larger than the holes 4 in the tube 2 so as to prevent them from falling. Since the tube 2 itself is flexible, the artificial flower leaves 6 do not fall even when the root parts 7 are inserted by expanding the holes 4.  As a result, the electric cord which is offensive in sight and which is to be hidden becomes a plant style so as to become nice to look at.

Title: Filter for removing nonmetallic inclusion in molten steel
Inventor: HIRAOKA TERUYOSHI
IPC: B22D11/116
Filed: 1983-02-25
Abstract: PURPOSE:To adsorb away a fine Al2O3 inclusion by installing cylindrical refractories of lime by paralleling the axial direction thereof in the flow direction of a molten steel, between the inflow port and outflow port for the molten steel in a tundish. CONSTITUTION:Cylinders 1 formed of lime refractories are stacked between a long nozzle 3 which charges a molten steel from a ladle into a tundish 2 and a charging nozzle 4 which charges the molten steel from the tundish 2 into a continuous casting mold. Said cylinders are held by a keep plate 5 and are thus prevented from floating. The refractories 1 are so disposed that the axial direction thereof parallels with the flowing direction of the molten steel in the tundish 2. Fine Al2O3 is thus absorbed by the refractories 1 and the refractories 1 are hardly eroded.

Title: Water feeding device
Inventor: SOFUE YOSHIKI
IPC: F04B49/06
Filed: 1986-02-13
Abstract: PURPOSE:To decrease a response time when there is a high flow rate, by a method wherein, by means of a comparing means, comparing a pressure in a piping with a pressure previously set in a pressure regulator, the integrating time of the regulator is switched to prevent the occurrence of hunting when there is a low flow rate. CONSTITUTION:When there is a low flow rate and water is stably fed, i.e., when a state of a set flow rate Qs > a process flow rate Qp is transferred to a state of a set flow rate Qs < a process flow rate Qp as a result of an amount of water used being increased, a flow rate is detected by a flow meter 6, and a signal therefrom is decided by a comparing circuit 11 of a PI constant switching circuit 9. If the Qs is less than the Qp, by means of a signal from the comparing circuit 11, a PI constant switching output circuit 12 outputs a switching instruction to a pressure regulator 8. In the pressure regulator 8, since, by means of an instruction from the PI constant switching circuit 9, a time of integrating control when the Qs is less than Qp is previously set, when a switching instruction is inputted, the time is switched. When there is a high flow rate, an integrating time is decreased and a response time is increased, and when there is a low flow rate, an integrating time is increased to prevent the occurrence of hunting phenomenon.

Filed: 1982-02-25
Abstract: PURPOSE:To form a titled converted gas having a very slight concn. of oxygen surely and easily with less fuel consumption, by mixing waste gases of combustion and gaseous fuel and modifying the gaseous mixture thereof with oxidation catalysts. CONSTITUTION:Gaseous fuel is mixed with, for example, waste gases produced by combustion in a gas furnace for purposes except for the formation of a converted gas in order to consume part of the oxygen in the waste gases by oxidation. The gaseous mixture thereof is fed into an oxidation catalyst mechanism 4. Then, the oxygen in the gaseous mixture reacts with C and H and forms oxide such as CO, CO2, H2O, etc. The concn. of the residual oxygen can be set accurately and can be kept as low as about <=10ppm by selecting the mixing ratio of the gaseous fuel and waste gases to be fed into the mechanism 4. The converted gas is passed through a cooler 5 to remove moisture therefrom by condensation and is then fed into a heating furnace for surface treatment, for example, an electric furnace 6 for blackening treatment of aperture grilles as a reacting atmosphere thereof.

Title: Power amplifier and radio transmitter
Inventor: ANSONII JIYON REI
IPC: H04B1/04
Filed: 1995-01-27
Abstract: PURPOSE: To provide a power amplifier, such as an amplifier adopting closed loop feedback (e.g. Cartesian feedback, for example), and a radio transmitter incorporating such an amplifier. CONSTITUTION: An amplifier circuit has an amplifier control loop and a loop- closing element 18 for selectively opening/closing the control loop, in response to a loop closing signal 40. More than one gain elements 30, 31, 32 and 33 outside the control loop are regulated in response to the loop-closing signal 40 and maintain an almost fixed gain between the input and output of the amplifier, while the loop is opened/closed. Since gain control is performed outside the loop, the negative influence upon phase shift or phase stabilization is reduced or eliminated, and a simple circuit can be designed by reducing a phase margin.
