Title: Discharge lamp lighting device
Inventor: KANDA TAKASHI
IPC: H05B41/24
Filed: 1992-02-15
Abstract: PURPOSE:To make peak values of discharge lamp current almost equal regardless of the power supplied from a pulsating current power source or a condenser. CONSTITUTION:A series circuit of a discharge lamp La and a switch element S1 is connected to both electrodes of a pulsating current power source provided by carrying out full wave rectification of a commercial power source AC. A condenser C is charged in a period where the voltage of the pulsating current power source is higher than the specific voltage of the discharge lamp, while a discharge lamp La is lighted by the load of the condenser C in a period where the voltage of the pulsating current power source is not more than the specific voltage of the discharge lamp. The terminal voltage of the condenser C and the voltage of the pulsating current power source are compared with one another by a comparator 7. The ON period of the switch element S1 is shortened by reducing the time constant of a single stable multivibrator 8 in a period where the terminal voltage of the condenser C is lower than the voltage of the pulsating current power source.

Abstract: PURPOSE:To reduce the sense of incongruity to a viewer accompanied with the quick change of picture quality by providing a coefficient updating buffer means which updates coefficient groups set to a transversal filter for pseudo ghost generation divisionally in plural prescribed periods and gradually displaying the ghost eliminated effect. CONSTITUTION:A ghost detecting part 2 compares a reference signal having waveform distortion with a preliminarily registered distortionless reference signal to detect the ghost, and coefficient groups ki (i=1 to n) to be set to the transversal filter for pseudo ghost generation are generated with a prescribed period and outputted to a coefficient update buffer part 5. Every time receiving the new coefficient group of the set object from the ghost detecting part 2, the coefficient updating buffer part 5 tentatively sets this coefficient group to a coefficient memory 5b. An old coefficient group ki' in a coefficient memory 5a is gradually updated to another coefficient group ki through a subtractor 5c, a coefficient device 5e, and an adder 5f by dividing it in a maximum number M of times of prescribed periods tau. Thus, the sense of incongruity accompanied with the quick change of picture quality is not given to the viewer.

Title: Carbon dioxide recovering material and method for recovering carbon dioxide utilizing the same
Inventor: SUZUKI KO
IPC: C01B32/50
Filed: 1991-01-29
Abstract: PURPOSE:To obtain a carbon dioxide recovering material having excellent carbon dioxide adsorptivity by using cellular powder or a granular substance consisting essentially of slaked lime. CONSTITUTION:A carbon dioxide recovering material of cellular powder or a granular substance consisting essentially of slaked lime. Slaked lime [Ca(OH)2] is converted into quick lime (CaO) in calcining limestone and water is added to disintegrate the quick lime. Thereby, crystals of the quick lime having about 1-10 size are formed and the resultant crystals are treated in a granulator to provide the powder or granular substance having the objective grain diameter. If the crystals are treated in a honeycomb extruder in place of the aforementioned granulator, a honeycomb structure can also be obtained. Although the slaked lime of the powder or granular substance thus produced is naturally a cellular substance, the specific surface is large and contact efficiency with gases to be treated is increased with smaller pores of the cellular substance. As a result, their conditions are as follows. The cellular substance having pores of <=10mum size and >=1.0m<2>/g specific surface area is more preferred.

Title: Current limiting conductor
Inventor: HAYASHI TATSUYA
IPC: H01L39/16
Filed: 1992-02-17
Abstract: PURPOSE:To suppress the partial quenching of a current limiting conductor so as to improve quench propagation and prevent fusion by providing sections, where either the thickness or the width of a superconductor made zigzag is made smaller than other sections, at a plurality of places. CONSTITUTION:In case of letting a certain rated current flow to an oxide superconductor 2 in superconductive condition, the current flows to the oxide superconductor 2. But, if a short circuit or the like occurs in a circuit and an excessive current flows, the oxide superconductor 2 becomes a normal conductor, being quenched, and has low resistance. The current is suppressed by the resistance generated in the oxide superconductor 2, and it shows current limiting effect. At this time, the quenching occurs at the folding parts 2a and 2b which are thinner than the center 2c, and is propagated from the turn-down parts 2a and 2b at both ends to the center 2c. Accordingly, the quenching widens quickly to the whole, and also partial quenching is suppressed.
