Abstract: A control apparatus for use in an imaging system that includes a first correcting member movable for image stabilization and provided to one of an image pickup apparatus and a lens apparatus detachably attachable to the image pickup apparatus, and a second correcting member movable for the image stabilization and provided to the other of the image pickup apparatus and the lens apparatus acquires first correction ratios of the first correcting member and the second correcting member for angular shake of the imaging system, and second correction ratios of the first correcting member and the second correcting member for shift shake of the imaging system.

Abstract: To suppress charging of a housing of a static eliminator while avoiding an influence on control of ion balance. In order to suppress the charging of the housing of the static eliminator, the housing is provided with a rear frame that is conductive. The rear frame is insulated from a placement surface of the static eliminator by an insulating member such as an insulating pad, an inner spacer, and an outer spacer, and movement of an electric charge from the rear frame to an earth via the placement surface is prevented. In addition, the rear frame is not connected to the earth, but is connected to a ground, that is, a wire electrically connected to each of a low-response detection circuit, a positive polarity high voltage power supply, and a negative polarity high voltage power supply.

Abstract: An ultrasonic flaw detection device comprises a flaw detection unit for transmitting and receiving ultrasound, a swinging mechanism for supporting the flaw detection unit to swing around a swinging axis, and a locking mechanism for switching between a swinging state and a locked state. The ultrasonic flaw detection device controls the locking mechanism and swinging mechanism such that when the flaw detection unit is moved along a direction tangential to a surface to be inspected from a position removed from a first end part of the surface to be inspected to a lock release position, the flaw detection unit is put in the locked state such that a direction tangential to a contact surface and the direction tangential to the surface to be inspected coincide, and the flaw detection unit is switched from the locked state to the swinging state after the flaw detection unit reaches the lock release position.

Abstract: An ionizer of a corona discharge type is configured to increase the yield of ions while minimizing contamination of a discharge electrode by foreign matters. In the ionizer, a gas path unit (11) supplied with clean gas has internal clean gas paths (50, 48) in an electrode assembly (40), and clean gas is released through each internal clean gas path (50, 48) to make a clean gas flow enclosing a front end portion of a discharge electrode (12). The electrode assembly (40) has a guard ring (46) encircling the discharge electrode (12), and the guard ring (46) has external air inlet openings (46b) permitting free passage of atmospheric air. The clean gas flow enclosing the tip of the discharge electrode (12) inhales atmospheric air through external air inlet openings (46b) of the guard ring (46) and changes to ionized air.
