Title: Optical fiber amplifier
Inventor: FUNAHASHI MASAAKI
IPC: H04B10/293
Filed: 1990-11-27
Abstract: PURPOSE:To monitor the state of an optical fiber amplifier from a remote place by giving repetitive micro bend to an erbium dope optical fiber at a specified frequency, and modulating a light signal in strength by change of its bent loss. CONSTITUTION:A bent loss giving part 11 is constituted of an optical fiber sandwiching jig 21 and an actuator 22 to drive it. A sub-signal given from a modulation circuit 14 to the actuator 22 changes pressure to hold an erbium dope optical fiber 31 in accordance with its amplitude. The erbium dope optical fiber 31 changes micro bent loss in accordance with change of its pressure and can give strength modulation to a light signal. In such a way, it is possible to detect the state of an optical fiber amplifier by giving strength modulation to the amplifying light signal and demodulating the strength modulated amount from the light signal transmitted in a terminal equipment.

Title: Dyeing of polyamide fiber cloth
Inventor: KONDO TOSHIYUKI
IPC: D03D15/00
Filed: 1990-11-27
Abstract: PURPOSE:To obtain a dyed cloth having high quality, bulkiness and soft feeling by dyeing a cloth made of a polyamide fiber having a boiling water shrinkage and an initial modulus lower than respective specific levels with a gas-flow dyeing machine. CONSTITUTION:A woven or knit fabric such as taffeta, twill, satin, georgette, tricot or gray sheeting made of a polyamide fiber (e.g. nylon 6, nylon 66 or nylon 610) having a boiling water shrinkage of <=5% and an initial modulus of <=350 kg/mm<2> is dyed with a gas-flow dyeing machine. The above woven or knit fabric is endlessly circulated in the dyeing machine at a machine temperature of 80-120 deg.C with a flow of a gas or a mixture of gas and liquid. The longitudinal tension of the fabric in the transfer direction can be decreased by the above circulation method to prevent the generation of defects such as wrinkle, wale streak, crack and glare liable to occur in polyamide fabric having low thermal stress. At the same time, the defects such as lead mark and needle streak generated in the production of fabric can be eliminated by this process.

Filed: 1988-12-20
Abstract: PURPOSE:To attain efficient program loading by allowing a writing means to write a pair of two names of a preceding execution program and the succeeding execution program in a non-volatile memory based upon the two executed programs. CONSTITUTION:The writing means 7 writes program names indicated from an input device 5 in the non-volatile memory 1 in the order of execution by increasing a pointer 23 one by one. When no name is written in the memory 1, only the former half part 21 of the names forming a pair is written, and in the other case, the latter half part 22 pointed out by the pointer 23 and the former half part 21 pointed out by the pointer 23 whose contents are updated only by one point are written. Since the relation between the two programs once executed is stored in the non-volatile memory 1, complex work allowing each user to input the name of the program in each time at the 2nd time or after can be removed.

Title: Timer signal generating circuit
Inventor: TANBACHI AKIRA
IPC: H03K3/03
Filed: 1987-12-18
Abstract: PURPOSE:To suppress energy consumption as much as possible by providing a limiting resistance, with which an impressing voltage can fall only by prescribed quantity, between an IC chip and a power source part and fetching the falling of the impressing voltage as a signal. CONSTITUTION:A power source voltage V0 is impressed through a limiting resistance 9 to an IC chip 1. When a first inverter goes into a transition area, an impressing voltage V1 of the chip 1 is lowered and the lowering of the voltage V1 causes a threshold to be decreased to the inverting operation of the inverter. Then, a current I1 is rapidly increased to be flown to the chip 1. At such a time, the voltage falling of the resistance 9 goes to be maximum and the voltage V1 of the chip 1 goes to be lower than a voltage VL, in which the normal operation of the inverter is guaranteed. As the result, the value of the voltage V1 is speedily returned to the normal value V0. Such a returning condition of the voltage V1 is converted in a pulse shape by a differentiation circuit 10 and a rectifier 11 and fetched as a timer signal S0 to be generated with a constant time interval.
