  • Patent number: 9988672
    Abstract: To provide a method for selectively detecting the methylation of particular cytosines in genomic DNA using a methylcytosine detection method using an anti-methylcytosine antibody to improve quantitativity and reliability. A method for detecting the methylated state of cytosine at a specific position contained in a nucleic acid, includes fragmenting the nucleic acid using a restriction enzyme; forming a double-stranded nucleic acid between the fragmented nucleic acid and a single-stranded nucleic acid having a base sequence capable of hybridizing with the fragmented nucleic acid but incapable of resulting in the formation of a base pair with cytosine at a specific position in the fragmented nucleic acid and a solid phase-binding site; binding the double-stranded nucleic acid on a solid phase using the solid phase-binding site; and measuring the amount of an antibody binding to the double-stranded nucleic acid on the solid phase.

  • Patent number: 6390807
    Abstract: The present invention relates to a structure in which an unburnt gas can be prevented from being diffused into a room while suppressing the generation of the unburnt gas during the extinction operation of a pot type oil burner. During the extinction operation, first of all, the supply of a fuel from fuel feeding means (35) to a pot (15) is stopped and conduction to an electric heater (31) is started. The rotation of each of a combustion fan (23) and a convection fan (11) is carried out continuously. While a second timer (67) counts a second time period, the convection fan (11) is rotated at a high speed. After the second time period is ended, the rotation of the convection fan (11) is switched from high speed rotation into low speed rotation. The low speed rotation is carried out continuously for a third time period counted by a third timer. After the third time period is ended, the rotation of the convection fan (11) is returned from the low speed rotation to the high speed rotation.

  • Patent number: 5964585
    Abstract: An oil burner capable of ensuring normal combustion of quality-deteriorated kerosine. A burner body including a vaporization section is fed with fuel and air from a fuel pump and an air fan, respectively. A combustion control unit controls the fuel pump and air fan to control a combustion quantity in the burner body. The combustion control unit increases the combustion quantity to a combustion level sufficient to permit tar collected in the vaporization section to be burned at a predetermined time interval. Also, the combustion control unit keeps the combustion quantity increased to the combustion level for a predetermined period of time which permits tar collected in the burner body prior to an increase in combustion quantity to the combustion level to be substantially exhausted. This permits the combustion quantity to be intermittently increased, to thereby ensure substantial exhaustion of tar collected in the burner body.

  • Patent number: 5524605
    Abstract: A non-open fire type cooking burner capable of exhibiting endurance, workability and safety. Heat combustion or exhaust gas produced by combustion in a burner body are guided to a heat exchanger made of metal and discharged through an exhaust pipe to an exterior of a room, respectively. The heat is then radiated to a ceramic plate arranged above the heat exchanger for cooking. An air shifter provided with an air-direction change-over damper is arranged so as to change over flowing of air, to thereby permit the cooking burner to be applied to space heating as well as cooking.
