Disclosed is a method for determining the sex of yellowtails, the method comprising a step of identifying whether an amino acid residue at position 143 in polypeptide encoded by the HSD17B1 gene of yellowtails is a glutamic acid residue or a glycine residue; a nucleic acid molecule or a primer set which is for use in said method; or a kit comprising the same, for determining the sex of yellowtails. The method according to the present invention is useful in that the genetic sex of yellowtails can be accurately determined.

Servo amplifier

A piston ring includes a plurality of first ring pieces placed inside the ring groove in a stacking manner such that the first ring pieces adhere to each other in the axis direction. The first ring pieces include respective piston ring gap portions each having end surfaces separated from each other in the circumferential direction of the first ring pieces such that the end surfaces face each other via a ring gap having a predetermined dimension. The respective piston ring gap portions of the first ring pieces are displaced from each other in the circumferential direction. A closing member is provided to close the piston ring gap portions of the first ring pieces in the radial direction of the first ring pieces.

Data transmitting device

A lens device includes a first lens system including a first lens, a second lens system including a second lens, a moving member configured to move in an optical axis direction of the first lens, and a physical structure configured to move the first lens in the optical axis direction and move the moving member in a direction opposite to a movement direction of a center of gravity of a physical system that includes the first lens.

Lens device, imaging system, movable object, and control method

A lens device includes a first electric motor, a second electric motor, a lens, a cam ring, a first gear, a second gear, and a controller. The cam ring is configured to drive the lens in a direction of an optical axis of the lens. The first gear is configured to transmit power generated by the first electric motor to the cam ring. The second gear is configured to transmit power generated by the second electric motor to the cam ring. The controller is configured to, when controlling the cam ring to stop rotating, first stop a rotation of the first electric motor and then stop a rotation of the second electric motor.

A light amount adjustment device includes a base member, a rotation member rotatably held with respect to the base member, and a light amount adjustment member engaged with the rotation member and configured to be driven by the rotation member to adjust an amount of passing light. The rotation member includes a first surface area in contact with the base member and a second surface area not in contact with the base member. A surface roughness of the first surface area is greater than a surface roughness of the second surface area.

Light amount adjustment device, imaging device, imaging system and moving object

The present disclosure provides a control device for controlling an imaging device. The control device includes an operation unit configured to be operated by an external force; a detection unit configured to detect an operation state of the operation unit; a processor configured to execute a program to: perform a predetermined operation based on the operation state of the operation unit; and invalidate an execution of the predetermined operation performed by the processor based on the operation state of the operation unit when the imaging device is connected to an object satisfying a condition.
