  • Patent number: 11499620
    Abstract: To provide a sprocket that reduces the influence of tension fluctuations concurrent with load torque variations to suppress noise and vibration, and that prevents an increase in tension fluctuations, noise, and vibration even when the chain tension is low and the load torque is small, and in regions where engagement between the chain and sprocket is free of the influence of tension. The sprocket has a plurality of seating points for the chain when the chain sits under no load set between adjacent pairs of the teeth such that their radial positions change in a circumferentially continuous manner. The radial positions of the seating points under no load have a variation pattern in which the radial positions increase and decrease depending on circumferential positions of the seating points.

  • Publication number: 20220297445
    Abstract: A label printer includes an under cover, a top cover, a label peel-off unit, an interfering member supporting member, an interfering member, and an interfered member. The top cover moves between a first position where the top cover is opened and a second position where the top cover is closed with respect to the under cover. The label peel-off unit moves between a third position where the label peel-off unit is opened and a fourth position where the label peel-off unit is closed with respect to the under cover. The interfering member abuts against an exterior member of the label peel-off unit. The interfered member is a part of the exterior member of the label peel-off unit, and protrudes toward an upstream side in the label conveyance direction and is at a position where the interfered member abuts against the interfering member.

  • Patent number: 11384675
    Abstract: The control section of a control apparatus executes a first control for operating a voltage application section such as to cause a current to flow in a first direction through a gas sensor in a first period, and a second control for operating the voltage application section such as to cause a current to flow in a second direction, opposite to the first direction, through the gas sensor in a second period. The control apparatus changes the length of at least one of the first period and the second period based on a comparison between a first measurement value, which is the absolute value of a value measured by a sweep measurement section during execution of the first control, and a second measurement value, which is the absolute value of a value measured by the sweep measurement section during execution of the second control.

  • Patent number: 10391778
    Abstract: A liquid cartridge includes: a casing including a liquid chamber; a liquid supply portion; a deformable member; a movable member; and an urging member. An internal pressure of the chamber is reduced as liquid flows out of the chamber. The deformable member protrudes from the casing in a cross direction crossing forward and rearward directions and has an internal space in communication with the chamber. The deformable member has such an elasticity that a dimension thereof in the cross direction becomes smaller as the internal pressure of the chamber is reduced. The movable member includes a detection portion, and a contact portion contacting the deformable member. The contact portion is in contact with the deformable member and disposed at one of positions further forward and further rearward relative to the deformable member. The urging member urges the movable member to move the contact portion toward the deformable member.
