  • Patent number: 11986134
    Abstract: To dispense a predetermined length of a sheet hygienically. In a sheet dispensing device, a sheet feeding mechanism feeds out a predetermined length for use of a sheet from a sheet dispensing port, and at this time, a part, of the sheet, located upstream of the sheet dispensing port in terms of a feeding direction of the sheet is held by a driving roller and a driven roller. The driven roller is biased by leaf springs to be pressed toward the driving roller. Consequently, the sheet is dispensed while hanging down from the sheet dispensing port. When a user pulls down the hanging sheet while holding it, the sheet is cut from the vicinity of a held part, so that the user can take the predetermined length for use of the sheet hygienically.

  • Patent number: 11894574
    Abstract: A battery pack is provided with a check valve including a cover body that is attached to a housing accommodating battery cells and a valve main body that is provided at an inner side of the cover body. The check valve exhausts gas discharged from the battery cells to outside the housing. The valve main body includes a moving portion disposed at an upstream side of the cover body. The moving portion is urged by an urging member to separate to the upstream side from the main body portion. When an internal pressure of the housing is at least a threshold value, the moving portion moves to the downstream side in opposition to urging force of the urging member. Plural stopper portions of the moving portion abut against the main body portion and limit the movement to the downstream side. Interstitial flow paths for the gas are formed between the stopper portions.

  • Patent number: 11858029
    Abstract: A three-dimensionally shaped round metallic wire having a cross-section non-circular portion in a predetermined portion without performing additional processing and having specified dimensional accuracy and accuracy of form. In an intermediate step in which the round metallic wire is processed in a predetermined three-dimensional shape, a cross-section non-circular portion forming machine 20 which forms the cross-section non-circular portion having a non-circular cross-sectional shape in at least one position is included. At the time of bending, the cross-section non-circular portion is held by a wire holding portion of a bending machine 30, and the bending is performed in the predetermined three-dimensional shape. Holding the cross-section non-circular portion causes relative rotation between the cross-section non-circular portion and the wire holding portion to be suppressed as compared with a case of the cross-section circular shape.

  • Publication number: 20230102281
    Abstract: A wet sheet with a predetermined length is securely provided while drying is prevented. When a motor control part receives a detection signal from a hand hovering sensor, a motor is driven from a standby state to rotate a driving roller. When a cutting line is detected by a cutting line detecting sensor, the driving of the motor is continued until a predetermined time set beforehand in which the detected cutting line reaches the side downstream of a contact point between the driving roller and a driven roller in terms of the feeding direction has elapsed, to be stopped. The detected cutting line is located downstream of the contact point between the driving roller and the driven roller in terms of the feeding direction. In front of the detected cutting line, the wet sheet for one sheet is present and is detected by the sheet detecting sensor.

  • Patent number: 8519701
    Abstract: A magnetic resolver includes a stator core made of magnetic material, coils, and a rotor. The stator core has a base plate and protrusions formed integrally with the base plate so as to protrude from a surface of the base plate in the thickness direction. The coils are provided around the respective protrusions. The rotor is disposed so as to face the surface of the base plate with the coils interposed therebetween. The overlapping area between the rotor and each of the protrusions changes with a change in a rotation angle of the rotor relative to the stator core. The stator core has through-holes that pass through the base plate and the respective protrusions in the thickness direction.

  • Patent number: 8459686
    Abstract: A horn switch mechanism 15 has a securing pin 31 serving as a support member, a movable member 32 serving as an insulating portion, a compression coil spring 35 serving as an urging member, and a contact terminal 34 serving as a movable contact. The securing pin 31 is fixed to a metal core 12 of a steering wheel body 11 and supports a bag holder 21 in such a manner that the bag holder 21 selectively proceeds toward and retreats from the metal core 12. The movable member 32 is arranged between the securing pin 31 and the bag holder 21 and electrically insulates the securing pin 31 and the bag holder 21 from each other. The coil spring 35 urges the bag holder 21 away from the metal core 12. The contact terminal 34 moves together with the bag holder 21. When the bag holder 21 moves toward the metal core 12 against the urging force of the compression coil spring 35, the contact terminal 34 contacts the securing pin 31 and permits conduction between the contact terminal 34 and the securing pin 31.
