Abstract: A quartz glass crucible having a crucible shape including straight body portion, curved portion, and bottom portion. The crucible includes: an outer layer made of an opaque quartz glass containing bubbles; and an inner layer made of a transparent quartz glass and having a thickness of greater than or equal to 1.5 mm. Concentrations of Na, K, and Li in the inner layer at 1 mm from an inner surface of the quartz glass crucible are less than 5 ppb by mass for Na, less than 5 ppb by mass for K, and less than 100 ppb by mass for Li. Average concentrations of Na, K, and Li in a thickness direction at the curved portion and the bottom portion in the outer layer are less than 10 ppb by mass for Na, less than 50 ppb by mass for K, and less than 180 ppb by mass for Li.

Abstract: The present technology relates to an information processing device, an information processing method, and a program capable of reducing a load in a case where an operator monitors the surroundings of a plurality of systems. The information processing device includes: a recognition unit that extracts a caution-needed region, which is a region requiring caution around each of a plurality of systems, on the basis of a plurality of captured images captured at different positions by the plurality of systems; and an image processing unit that generates a first bird's-eye view image on the basis of the plurality of captured images including a plurality of the caution-needed regions. The present technology can be applied to, for example, a server that mediates monitoring of a system and intervention in the system by an operator.

Abstract: An information processor according to the present disclosure includes a deviation amount predictor that predicts, on the basis of a first sensor value acquired by bringing a tactile sensor into contact with a connector and a second sensor value acquired by bringing the tactile sensor into contact with a first candidate location of an insertion target for the connector, a positional deviation amount between the connector and the insertion target.

Abstract: A timepiece includes a case, a dial having a circular plate shape and accommodated in the case, an inner rotating ring formed in a ring shape along an outer peripheral edge of the dial and rotatable in a circumferential direction, a rotation operation unit configured to rotate the inner rotating ring, and a rotation restriction unit configured to restrict an operation of the rotation operation unit. The inner rotating ring includes a plurality of tooth portions. The rotation operation unit includes a rotation shaft portion rotatable around a shaft center along a radial direction of the dial, and a drive transmission gear provided in the rotation shaft portion and meshing with the tooth portions to rotate the inner rotating ring. A plurality of locking portions is formed in the drive transmission gear at different positions in a direction around a shaft. The rotation restriction unit includes a lock receiving portion biased toward the locking portion and detachably locked to the locking portion.

Abstract: A method for evaluating a quartz glass crucible constituted by an outer layer formed of an opaque quartz glass containing a bubble, and an inner layer formed of a transparent quartz glass. The method includes steps of preparing a quartz glass crucible to be evaluated, irradiating the quartz glass crucible to be evaluated with ultraviolet rays as an excitation light, detecting a blue fluorescence emitted from the quartz glass crucible irradiated with the ultraviolet rays, and evaluating a state of oxygen deficiency defects in the outer layer of the quartz glass crucible on the basis of existence or non-existence of the blue fluorescence. The method allows hydrogen doping and water vapor introduction to attain nondestructive and easy evaluation on the state of the oxygen deficiency defects generated in the quartz glass crucible.

Abstract: A binder for an electrochemical element, comprising: a polymer having a carboxyl group and/or a salt thereof, a polymer having an amide group and/or an amide bond; or a polymer having a carboxyl group and/or a salt thereof and an amide group and/or an amide bond.

Abstract: A binder for an electrochemical element, containing a polymer having both an anionic unit and a nonionic unit, wherein a part of the anionic unit is neutralized, and a degree of neutralization of the anionic unit in the polymer is 95% or less. Optionally, the anionic unit in the polymer is a carboxyl group, a sulfo group, a phosphonate group, a phosphinate group or a phosphate group.
