  • Patent number: 11597898
    Abstract: A number analyzing method, a number analyzing device, and a storage medium for number analysis are disclosed, which enable, with high accuracy, analysis of the number or number distribution of particulate or molecular analytes according to the kinds of the analytes. A computer control program is executed on the basis of a data group of particle-passage detection signals which are detected by a nanopore device in accordance with passage of subject particles through a through-hole. Also, a particle type distribution estimating program is executed, to estimate probability density on the basis of a data group based on feature values indicating feature of the waveforms of pulse signals which correspond to the passage of particles and which are obtained as the particle-passage detection signals. Thus, the number of particles can be derived for each particle type.

  • Publication number: 20230048535
    Abstract: A battery lid is formed of a metal plate integrally formed with a valve and a surrounding plate portion surrounding the valve which facilitates rupturing the valve at a predetermined pressure. The valve includes a pressure receiving plate portion having a bending groove, and bendable from the bending groove by applied pressure, and a thin plate portion thinner than the thickness of the surrounding plate portion, and connects the pressure receiving plate portion to the surrounding plate portion. The thin plate portion has a rupture groove passing through extension sections on the respective lines extending from the bending groove. As the pressure receiving plate portion is deformed by the pressure applied to the valve, the extension sections are pulled more strongly than are the other sections in the valve. Therefore, when a predetermined pressure is applied, the valve is ruptured from the extension sections of the rupture groove.

  • Patent number: 11568921
    Abstract: A device includes an array of memory cells having a word line coupled to at least a subset of the array, a queue, and control logic. The control logic: detects a first read command to read first data from a first page of the subset; accesses a second read command in the queue, the second read command to read second data from a second page of the subset; causes a voltage applied to the word line to ramp up to an initial value; causes the voltage to move to a target value; directs a page buffer to sense the first data from a first bit line coupled to the first page of the subset; directs the page buffer to sense the second data from a second bit line coupled to the second page of the subset; and causes the word line to be discharged.

  • Publication number: 20220320675
    Abstract: According to the present disclosure, there is provided a sealing plate equipped with a gas discharge valve that reduces processing load and work hardening during molding. A gas discharge valve of a sealing plate 1 disclosed herein has a flat plate-shaped base portion and a protruding portion protruding from a first surface of the base portion in a first direction, an annular thin-walled portion having a thickness smaller than the thickness of the protruding portion is provided around the protruding portion, and a first surface of the thin-walled portion is substantially on the same surface as the first surface of the base portion. In the gas discharge valve having the above configuration, the total amount of metal that is plastically deformed is reduced by limiting the formation region of the thin-walled portion to the periphery of the protruding portion.
