Title: Light amplifier
Inventor: TAMURA YASUAKI
IPC: H01S3/07
Filed: 1990-11-26
Abstract: PURPOSE:To reduce the size and cost of a light amplifier by forming one light isolator in such a manner so as to serve as two light isolators. CONSTITUTION:Input signal light 2 from an input port 1 is multiplexed with excitation light 4 from an excitation light source 3 by a light synthesizing device 5 to enter the first light beam connection system of a light isolator 6. Light which passes through the light isolator 6 and is emitted from the first light beam connecting system is guided to an erbium doped fiber 7, and the signal light is light-amplified here. The light-amplified signal light is again entered in the second beam connection system of the light isolator 6 to be output to an output port 8 through the light isolator 6. In this case, the light isolator 6 acts in same manner as two light isolators in the case where the light isolators are respectively inserted in the input side and output side of the erbium doped fiber 7. Thus, expensive light isolators are reduced to one, the reduction of cost of a light amplifier can be achieved, and the space saving can be accomplished.

Title: Advancing control of melt flow rate and reactor slurry concentration in polypropylene slurry method
Inventor: ROBAATO JIYOSEFU TOPURISU
IPC: C08F4/64
Filed: 1988-12-16
Abstract: PURPOSE: To produce the polymer with a desired melt flow rate at a low cost by producing a measurement signal of a liquid phase temperature, a measurement signal of a gas phase pressure, and a measurement signal of a gas phase H 2 /monomer concentration ratio and combining the signals to control the melt flow rate of a produced polymer.  
     CONSTITUTION: In the polymerization of a polypropylene in a reactor 12 including gas phase and liquid phase reaction by controlling a polypropylene slurry, a temperature of the liquid phase is measured to produce a 1st measurement signal proportional to the temperature, a temperature of the gas pressure is measured to produce a 2nd measurement signal proportional to the pressure, a ratio of hydrogen concentration to propylene concentration in the gas phase is measured to produce a 3rd measurement signal proportional to the ratio. The signals 70 are given to a computer 64 to combine them automatically to allow the computer 64 to produce a calculated output signal in response to the signals and denoting a momentary melt flow rate(MFR) of the polymer generated in the reactor 12. The MFR is compared with a desired melt flow rate and the ratio of hydrogen concentration to propylene concentration in the gas phase is adjusted to keep the desired ratio of hydrogen concentration to propylene concentration and hence the objective polymer is produced with the desired melt flow rate.

Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To suppress the waste of power at the time of opening a door or/and a window so as to improve the service life of each equipment and obtain an optimum air-conditioning state by controlling the position of a blowoff port according to a signal from a means for detecting opening/closing of the door or/and window of a cabin, and a target blowoff temperature signal. SOLUTION: According to an opening/closing signal from a door opening/ closing detecting sensor 30 or/and a window opening/closing detecting sensor 31, a control device 27 controls the position of a blowoff port and the air quantity and computes the target blowoff temperature (TOC). Upon the input of an opening signal from the door opening/closing detecting sensor 30 or/and the window opening/closing detecting sensor 31, the control device 27 switches over to forced control according to TOC at that time and forcibly limits a blowoff position according to the respective conditions of TOC<=25 deg.C, 25 deg.C<=TOC <=40 deg.C and 40 deg.C<=TOC. Power consumption is therefore suppressed to a low degree, and an efficient air-conditioning state can be obtained.

Title: Catalyst deterioration judging device of internal combustion engine
Inventor: NAGAI TOSHINARI
IPC: F02D41/02
Filed: 1995-12-07
Abstract: PROBLEM TO BE SOLVED: To correctly judge whether or not a three-way catalyst is slightly deteriorated. SOLUTION: An upstream side O2 sensor 23 is arranged in an exhaust gas passage on the upstream side of a three-element catalyst 14, and a downstream side O2 sensor 24 is arranged in an exhaust gas passage on the downstream side of the three-element catalyst 14. When the locus length ratio of the locus length of the output of the downstream side O2 sensor 24 to the locus length of the output of the upstream side O2 sensor 23 exceeds the threshold level, the threeway catalyst 14 is judged to be deteriorated. Deterioration of the three- way catalyst 14 is judged when the three-way catalyst 14 is started to be activated. The threshold level is set lower as the temperature of the downstream side sensor 24 is lower.

Abstract: PURPOSE:To enable the high speed of operations and to reduce the chip area at the time of an integration by driving a selected word line in short time. CONSTITUTION:The most significant bit signal An of a line address signal is made a 0 level, and when the writing and reading of information is performed for the memory cell within the plural memory blocks 31A of one group, the driving signal phi1 generating in response to a signal/RAS in a driving signal generation circuit 37 is outputted as a signal phi3 based on the signal An in a driving signal selection circuit 38. The output terminal of a signal phi4 performs electric discharge to the 0 level. At this time, the line decoders where the signals phi3 are supplied are the only plural lines decoders 34A of one side. Therefore, the wirings transmitting the signal phi1 to the decoders 34A become the half of the number of conventional wirings, and wiring capacity and resistance is also reduced. Therefore, the time till when a selected word line 32 rises to one level is drastically reduced, and as a result, operation speed can be improved.
