  • Publication number: 20240329088
    Abstract: The present disclosure provides a voltage detector capable of alerting a worker to nearby presence of a voltage source regardless of the worker's awareness simply by being worn on the worker's body. In a voltage detector for detecting approach to a voltage source, a voltage induced in a human body due to approach to a voltage source is measured by a first electrode of a detection circuit, a voltage to ground is measured by a second electrode of the same circuit, the detection circuit captures a current generated due to a difference between an electric potential of the first electrode and an electric potential of the second electrode, and output from the detection circuit is displayed for warning when the human body insulated from the ground approaches the voltage source.

  • Patent number: 9779921
    Abstract: An apparatus includes a process chamber, a substrate holder arranged in the process chamber, a first shield provided on the peripheral portion of the substrate holder, and a second shield provided inside the process chamber. The internal space of the process chamber is partitioned into an outer space and a process space to process the substrate, by at least the first shield, the second shield, and the substrate holder. The substrate holder can be driven along a driving direction perpendicular to a substrate holding surface. The length, in a direction parallel to the driving direction, of a minimum gap portion having a minimum size in a direction perpendicular to the driving direction between the first and second shields does not change even if the substrate holder is driven in the driving direction.

  • Patent number: 9099757
    Abstract: Provided is a battery which has less tendency to experience delamination or loss of short circuit prevention layer and/or active material layer during manufacture and use. A battery comprising a laminated electrode assembly in which a positive electrode, a negative electrode, and a separator are laminated together; wherein an alumina-containing layer containing ?-alumina particles is formed on at least one species selected from among the group consisting of the positive electrode, the negative electrode, and the separator. The fact that alumina-containing layer(s) is or are made to contain ?-alumina particles makes it possible to obtain high bond strength between alumina-containing layer(s) and electrode(s) comprising metal(s), current collector(s) and/or active material(s) making up electrode(s), and/or separator(s).
