Abstract: An electromagnetic relay includes a fixed contact, a movable contact, a movable contact piece, a movable iron core, a drive shaft, a coil, and a stopper. The movable iron core is movable in a moving direction including a contact direction in which the movable contact approaches the fixed contact and a separation direction in which the movable contact separates from the fixed contact. The movable iron core includes a shaft hole extending in the moving direction. The drive shaft is connected to the movable contact piece. The drive shaft extends through the shaft hole. The drive shaft is fixed to the movable iron core. The coil generates a magnetic force to move the movable iron core in the moving direction. The stopper is connected to the drive shaft. The stopper restricts a movement of the movable iron core with respect to the drive shaft in the moving direction.

Abstract: The electromagnetic relay includes a fixed terminal, a fixed contact connected to the fixed terminal, a movable contact piece moving in an opening direction and a closing direction with respect to the fixed terminal, a movable contact connected to the movable contact piece and being arranged to face the fixed contact, a coil generating an electromagnetic force to move the movable contact piece, and a drive circuit controlling a current to the coil. The drive circuit increases the current at a first increase rate in a first period that includes a period from a start time when the current starts to flow in the coil to before a contact time point at which the movable contact contacts the fixed contact. The drive circuit increases the current at a second increase rate larger than the first increase rate in the second period that includes a period after the contact time point.

Abstract: An electromagnetic relay includes a fixed contact, a movable contact, a movable contact piece, a case, and an adhesive material. The movable contact is disposed to face the fixed contact. The movable contact piece is connected to the movable contact. The movable contact piece is movable between a closed position in which the movable contact is in contact with the fixed contact and an open position in which the movable contact is separated from the fixed contact. The case accommodates the fixed contact and the movable contact. The adhesive material is disposed in the case. The adhesive material captures foreign matter in the case.

Abstract: A driving control apparatus is configured to control a driving unit that moves relative to each other a vibrator that is excited to vibrate by applying a first driving signal and a second driving signal that have a phase difference with each other, and a contact member that contacts the vibrator. The driving control apparatus includes a first control unit configured to control the phase difference, and a second control unit configured to control a voltage amplitude of each of the first driving signal and the second driving signal. The second control unit controls the voltage amplitude so that a change rate of the voltage amplitude increases as an absolute value of the phase difference decreases.

Abstract: An image pickup apparatus is configured to change a shooting process based on data on a shot image. The image pickup apparatus is configured to, when the image pickup apparatus changes the shooting process, assign greater weights to the data on the shot image based on an instruction from a user than to the data on the shot image automatically processed.
