  • Patent number: 11965095
    Abstract: A bio-electrode composition contains (A) an ionic polymer material. The component (A) is a polymer compound containing: a repeating unit-a having a structure selected from the group consisting of salts of ammonium, sodium, potassium, and silver formed with any of fluorosulfonic acid, fluorosulfonimide, and N-carbonyl-fluorosulfonamide; and a repeating unit-b having a side chain with a radical-polymerizable double bond in a structure selected from the group consisting of (meth)acrylate, vinyl ether, and styrene. Thus, the present invention provides: a bio-electrode composition capable of forming a living body contact layer for a bio-electrode to enable signal collection immediately after attachment to skin and prevention of residue on the skin after peeling from the skin; a bio-electrode including a living body contact layer formed of the bio-electrode composition; and a method for manufacturing the bio-electrode.

  • Publication number: 20240098365
    Abstract: A lens apparatus connected to a camera, includes: a focus lens; a driving unit which drives the focus lens; an operation input unit; a mode switcher that switches between first and second modes relating to selection between AF and MF and a selection of an operation target of the operation input unit, and a controller, in which the controller, in the first mode, controls the driving unit based on an input from the operation input unit and controls a driving of the focus lens unit in MF, and in which the controller, in the second mode, outputs a control signal to change image pickup parameter based on input from the operation input unit, controls the driving unit in AF based on an AF control signal input from the camera when a set value input from the camera is AF-executable, and does not perform AF when the set value is AF-not-executable.

  • Publication number: 20230358776
    Abstract: An automatic analyzer capable of confirming the amount of sample aspirated by a sample dispensing unit is provided. An automatic analyzer that analyzes a sample includes an incubator which holds a reaction container in which a liquid mixture of the sample and a reagent is accommodated, a sample dispensing unit which dispenses the sample by aspirating the sample from a sample container in which the sample is accommodated and storing the aspirated sample in a storage portion and then discharging the sample to the reaction container, and a measurement portion which measures the amount of sample in the storage portion on the basis of a detected signal obtained by detecting light passing through the storage portion while irradiating the storage portion with light.

  • Patent number: 4738096
    Abstract: An open type metal cord has a plurality of cord units each constituted by at least one preformed metal wire member. The wire members within a given cord unit have the same preforming ratio but have a different ratio from that of the wire members within another cord unit. A difference between the largest preforming ratio and the smallest preforming ratio in cord units falls within the range of 0.20 to 0.40. In this case, the maximum preforming ratio possible for the wire members is 1.65 and the minimum preforming ratio possible for the wire members is 1.05. A total number of wire members constituting a metal cord according to the present invention is 3 to 5.
