  • Publication number: 20230139371
    Abstract: Provided is a technique that can improve a physical sensation of a user during treatment. A low-frequency treatment device according to one aspect of the present invention includes a pad portion configured to be able to supply a low-frequency pulse current to a contact target, and an output unit configured to output, during supply of the low-frequency pulse current by the pad portion, at least one of light and sound synchronized with a change in a supply state of the low-frequency pulse current. For example, the low-frequency treatment device according to one aspect of the present invention includes a control unit configured to perform control of supply of the low-frequency pulse current by the pad portion and control, in conjunction with the control of supply of the low-frequency pulse current, of output of at least one of the light and sound by the output unit.

  • Patent number: 11166639
    Abstract: A flow control valve includes a bobbin around which a solenoid coil is wound, a plunger inserted into the bobbin so as to be capable of sliding, a core in which is provided an outflow port from which a fluid flows, a spring that biases the plunger in a direction away from the core, and a valve body incorporated into the plunger so as to be disposed facing the outflow port. During a non-operating state, the valve body is disposed at a first position distanced from the outflow port. During an operating state, the plunger is pulled toward the core against a biasing force of the spring, and is not in contact with the core when the valve body is at a second position in which the valve body blocks the outflow port.

  • Patent number: 11020012
    Abstract: A flow rate control apparatus includes a flow rate detection unit that detects the flow rate of a fluid flowing through a solenoid valve, a correlation storage unit that stores a correlation between a flow start point voltage at which the fluid starts to flow through a sample solenoid valve, which has substantially the same characteristic as the solenoid valve, and a limit voltage at which the sample solenoid valve is fully open, and a control unit that, when starting control of the flow rate of the fluid, changes the driving voltage of the solenoid valve, obtains the driving voltage at a time when the start of flowing of the fluid is detected as the flow start point voltage, and uses the correlation for the sample solenoid valve to set the driving voltage of the solenoid valve within a range between the flow start point voltage and the limit voltage.

  • Patent number: 10080502
    Abstract: In a solenoid valve, a bobbin and a solenoid coil are accommodated in a casing. A rod-shaped plunger is slidably inserted into the bobbin. A core provided with a flow port through which a fluid flows is disposed on one side of the casing. A valve body is attached to one end opposing the flow port of the plunger. In a non-operating period during which a solenoid coil is in a non-energized state, the valve body moves away from the flow port due to the biasing force applied by the biasing portion and another end of the plunger protrudes outward from the casing through the through hole, abuts against lock portions disposed outside of the casing, and is thereby locked. The lock portions can be elastically deformed by an external force such that separation of the plunger and the valve body from the casing is allowed.

  • Patent number: 9316544
    Abstract: Provided is an electronic thermometer that is inexpensive, has fast thermal response, and suppresses bending and directional misalignment of the lead of the temperature sensor during assembly of the electronic thermometer. The electronic thermometer includes: a temperature sensor that includes a temperature sensing unit that measures the body temperature of a measurement subject and a lead having one end that is fixed to the temperature sensing unit; a hollow housing that houses the lead, and in which the temperature sensing unit is arranged on the tip side; a printed circuit board to which the other end of the lead is fixed; and an assembly that includes the printed circuit board and is housed in the housing. The assembly includes an extension portion extending toward the tip side of the housing. The extension portion has a guide portion that orients the extending direction of the lead.
