  • Publication number: 20240011960
    Abstract: An ultraviolet ray emitter includes an inner tube, an outer tube arranged around the inner tube, the outer tube defining between the outer tube and the inner tube, a discharge space where discharge gas is sealed, a pair of electrodes that causes discharge in the discharge space, and an auxiliary light source that assists excitation of discharge gas by emitting light to discharge gas from the outside of the outer tube. The outer tube is less likely to allow passage therethrough of ultraviolet light generated by excitation of discharge gas than the inner tube but allows passage therethrough of light having a wavelength emitted from the auxiliary light source.

  • Publication number: 20230349879
    Abstract: An inspection apparatus includes a measurement unit, a flow-in tube for flow of sample water into the measurement unit, a connection portion that connects a sample tube and the measurement unit to each other, a liquid sending portion that sends sample water to the measurement unit, a pressurization pump that increases a pressure in the inside of the sample tube, and a controller. The controller controls operations of the liquid sending portion and the pressurization pump to suppress within a prescribed range, variation in pressure applied to sample water until sample water reaches the measurement unit from the inside of the sample tube.

  • Publication number: 20230314356
    Abstract: A conductivity meter includes a measurement unit including an electrode arranged as being in contact with sample water and a substrate on which a circuit that processes information outputted from the measurement unit is mounted. The measurement unit and the substrate are connected to each other, with a wall portion being interposed, the wall portion partitioning a space in a housing into a water section and an electric section. The measurement unit is arranged on a first surface of the wall portion on a side of the water section such that the electrode is located in an opening provided in the wall portion. The substrate is arranged on a second surface of the wall portion on a side of the electric section such that an electrode contact that electrically connects a power supply and a circuit to each other is located in the opening.

  • Patent number: 11739006
    Abstract: A water quality measurement device 1 includes a twin tube excimer lamp 2. The inflow pipe 3 is connected to one end of the inner tube 21 of the excimer lamp 2, and the outflow pipe 4 is connected to the other end of the inner tube 21 of the excimer lamp 2. The detector 5 that measures the conductivity of sample water is interposed in the outflow pipe 4. In the water quality measurement device 1, sample water sequentially flows through the inflow pipe 3, the inner tube 21 of the excimer lamp 2, and the outflow pipe 4. Hence, the channel in the water quality measurement device 1 can be simplified. Additionally, the sample water is oxidized by being irradiated with UV light in the inner tube 21 of the excimer lamp 2. Hence, it is possible to irradiate the sample water with UV light from the excimer lamp 2 efficiently.

  • Patent number: 9061882
    Abstract: A fastening member according to the invention includes right and left sewn areas which are sewn to one member out of a cushion member and a cover material, a hook-and-loop fastener area which is disposed between the right and left sewn areas and which has a plurality of female engagement elements formed on one face thereof, and a connection area which connects between the hook-and-loop fastener area and the respective sewn areas. Here, the connection area is configured to have a lower yarn density than that of the sewn areas and allows the hook-and-loop fastener area to be displaced relatively to the sewn areas. According to the fastening member of the invention, since the fastened cover material can be easily displaced against the cushion member, wrinkling occurrence at the cover material can be prevented when the cover material is assembled to the cushion member.
