  • Patent number: 12064460
    Abstract: According to a conventional method for treatment of Sandhoff disease and Tay-Sachs disease comprising administering a modified ?-subunit to a patient in the form of a protein, it is necessary that administration be performed frequently. This invention relates to a recombinant adeno-associated virus virion comprising: capsomere comprising a protein capable of forming a virus virion; and a polynucleotide packaged in the capsomere comprising a promoter sequence and nucleotide sequences operably linked to the promoter sequence encoding a first amino acid sequence derived from the amino acid sequence of the ?-subunit of wild-type human ?-hexosaminidase composed of amino acids 55 to 556 in the sequence as shown in SEQ ID NO: 28 by substitution of amino acids 312 to 318 with glycine, serine, glutamic acid, proline, serine, glycine, and threonine in that order and a second amino acid sequence, which is an amino acid sequence of a signal peptide linked to the N terminus of the first amino acid.

  • Patent number: 12066115
    Abstract: An electromagnetic valve manifold includes an electromagnetic valve and a manifold base. The electromagnetic valve includes a manual shaft. The manual shaft is configured to be manually operated to be switched between a first switching position, in which the manual shaft allows movement of the valve member relative to the valve hole, and a second switching position in which the manual shaft restricts movement of the valve member relative to the valve hole. The manual shaft includes a projection that is projected into and retracted from the valve hole. The valve member includes at least one recess in an outer surface of the valve member. The manual shaft is configured such that, in a state in which the manual shaft is located in the second switching position, the projection is projected into the valve hole and engaged with the recess, so as to restrict movement of the valve member.

  • Publication number: 20240239102
    Abstract: Provided is a liquid ejection apparatus, liquid ejection method, dispensing apparatus, and compound introduction apparatus capable of inhibiting contamination of a liquid after being ejected. The liquid ejection apparatus has an ejection unit having an ejection part and an ejection energy generation element that ejects a liquid from the ejection part by using a principle of inkjet ejection into an internal space in a storage part capable of storing the ejected liquid. When ejecting the liquid, the ejection unit covers an opening portion of the storage part to thereby screen the internal space in the storage part from an external space.

  • Patent number: 7003234
    Abstract: Disclosed is a toner recycle device for supplying recovered toner into a developing device again and reusing it. The ratio of the amount of the recovered toner to be supplied into the developing device to the amount of new toner is arbitrarily increased or reduced. Further, as the remaining amount of the new toner reduces, one or a plurality of the following three processing steps of a toner save mode are executed: (1) to increase the ratio of the amount of the recovered toner, which is supplied into the developing device, to the amount of the new toner; (2) to reduce the total amount of the recovered toner and the new toner to be supplied; and (3) to stop the new toner to be supplied into the developing device and to supply only the recovered toner. Furthermore, an ordinary mode and the toner save mode are automatically switched or arbitrarily switched manually.

  • Patent number: 6863224
    Abstract: A bottle unit (30) of a liquid atomizing apparatus is provided with: a bottle section (31) reserving a chemical liquid (L); a horn oscillating member (40) to whose a distal end the liquid (L) in the bottle section (31) is fed; and a mesh member (1) having a number of fine pores (2), and mounted to an end surface of the distal end (41) of the horn oscillating member (40) in contact therewith. The bottle section (31) is constituted of a large capacity section (B) and a small capacity section (b) in communication with the large capacity section (B) through an opening (32), and opposing to the distal end (41) of the horn oscillating member (40). The small capacity section (b) is formed such that the liquid (L?) therein is in contact with a point in the proximity of the contact section between the distal end (41) of the horn oscillating member (40) and the mesh member (1).

  • Patent number: RE40058
    Abstract: A method and apparatus for discriminating bottle types, for stirring the toner, and for detecting the amount of toner remaining in the toner bottle. A toner bottle is adapted to fit the apparatus for discriminating toner bottle types, and a toner bottle is adapted for the apparatus for stirring toner. The genuineness of the toner bottle product is checked by sensing a rib assumed to be formed with a predetermined length on the outer surface of the toner bottle. Toner is stirred by continuously rotating the toner bottle in forward and reverse directions. The toner bottle can be easily rotated in the forward and reverse directions by sensing the rib of the toner bottle by using the sensor. Since the load of rotation of the toner bottle changes in accordance with the amount of remaining toner, the rotational speed of the toner bottle is sensed by using the sensor to check whether toner is close to empty.
