  • Patent number: 11543620
    Abstract: Provided are a lens barrel and an imaging device, with which it is possible to lock an optical member of which the movement in an optical axis direction is made free in a case where there is no electrification, particularly to hold the optical member in a locked state without use of electric power. A movable frame that holds a focus lens is driven in the optical axis direction by a linear motor. In a case where the movable frame is to be locked with the linear motor being not electrified, the movable frame (engagement portion) is caused to abut onto a restriction portion at an end portion of the movable range of the movable frame and a locking ring is caused to rotationally move to a locking position by an electric actuator. Accordingly, the movable frame is fixed by the restriction portion and a locking portion of the locking ring to become unable to move.

  • Publication number: 20220307456
    Abstract: Provided is a start controller for an engine capable of reducing torque of a starter consumed to start the engine. The start controller includes a stop position sensor that detects a position of a piston in each cylinder at an engine stop time, an intake pressure sensor that detects an intake pressure in an intake passage, and a processor that determines whether the position of the piston in each of the cylinders detected by the stop position sensor is within a specified target range after the engine is stopped. In the case where it is determined that the position of the piston in each of the cylinders after the engine stop is out of the target range and the intake pressure detected by the intake pressure sensor is lower than an atmospheric pressure, the engine is started by a motor even when an engine start condition is not satisfied.

  • Patent number: 11440315
    Abstract: There is provided an ink jet recording apparatus including an ink jet head and a drive circuit. The ink jet head forms an image on a recording medium in response to a drive signal applied to multiple piezoelectric elements. The drive signal causes multiple pressure chambers corresponding to the multiple piezoelectric elements to expand or to contract in volume and causes ink in the multiple pressure chambers to be discharged from multiple nozzles. The drive circuit generates a drive signal for discharging multiple liquid droplets to one pixel for combining the multiple liquid droplets together and applies the drive signal to each of the multiple piezoelectric elements of the ink jet head. The drive signal includes multiple discharge pulses which make velocities of tips of respective liquid columns substantially same after a predetermined time from starting of ink discharge from the nozzles.
