摘要:
In an ultrasonic imaging apparatus, an object to be inspected is scanned while being irradiated by a generated ultrasonic beam. Echo signals from the object are received and a plane image and a cross-sectional image formed from the received echo signals are displayed. A marker indicating the focus position of the ultrasonic beam and a marker indicating the setting range of a detection gate are synthesized and displayed on the cross-sectional image. The plane image of the portion assigned by the focus position and the depth range on the cross-sectional image is obtained.
摘要:
Ultrasonic apparatus that automatically adjusts the focus of ultrasonic waves to a desired depth within an object includes an ultrasonic probe which irradiates a focused ultrasonic beam onto an object to be inspected and a receiver which receives ultrasonic waves reflected from the object. A desired focusing depth is set and the inherent focal length of the probe and the velocity of sound within the object are detected to evaluate a distance between the probe and the object at which the focus of the probe coincides with the desired depth. The distance between the probe and the object is adjusted to coincide with the evaluated distance.

An amorphous core transformer is provided which is capable of effectively suppressing influences, fluctuation, displacement or the like of a coil caused by an electromagnetic mechanical force or the like. In an amorphous core transformer 100 including an amorphous core 101, a plurality of coils 102 in which the amorphous core 101 is inserted and a fixing metal frame 110 that assembles the coils 102 and the amorphous core 101, the inter-coil member 106 is interposed between the neighboring coils 102 and the inter-coil member 106 is positioned and held by a positioning member 107. Thus, it is possible to prevent the coils 102 from being deformed or displaced beyond the inter-coil member 106 and maintain the shape of the coils 102.

Disclosed is a wound iron core (3) for a static apparatus in which magnetic paths in the inside of the wound iron core are subdivided to improve iron core characteristics. The iron core (3) is configured by using two or more kinds of magnetic materials (11 to 14) with different magnetic permeabilities to form laminated blocks with single plates or a plurality of laminated plates and by alternately arranging the laminated blocks with different magnetic permeabilities from the inner circumference. An iron core material (14) with large magnetic permeability out of iron core materials with different magnetic permeabilities is arranged on the inner circumference side. Further, when the iron core materials with different magnetic permeabilities are alternately arranged, the iron core materials (11) with the same magnetic permeability are configured to gradually change in thickness to ease an excessive magnetic flux density distribution in the iron core. A ring-shaped iron core is configured such that a plurality of block-like laminated members, which are each formed by laminating a plurality of strip-like amorphous material thin plates, are laminated and formed into a ring shape and a sheet-like non-magnetic insulation material is arranged between the n-th (n: an integer of two or more) layer of the ring-shaped block-like laminated members from the most inner circumference side and the (n+1)-th layer of the ring-shaped block-like laminated members from the most inner circumference side.

In the lighting control device according to the exemplary embodiment, the detection section detects the presence or absence of a person in a lighting area and a movement speed of a person, based on an image data of the lighting area that is lighted by a light source of a plurality of lighting apparatuses and is acquired from an imaging device. A decision section decides whether each of division areas is a stay area or a non-stay area based on the movement speed of a person detected by the detection section. A lighting control section performs different lighting controls on the lighting apparatus of the division area decided as the stay area by the decision section and the lighting apparatus of the division area decided as the non-stay area.

A sheet conveying device includes an attraction belt, multiple rollers, a charging device, and a contacting and separating device. The attraction belt is arranged to face the upper surface of a stacked sheet stack. The multiple rollers stretch the attraction belt with tension. The charging device charges a surface of the attraction belt. The contacting and separating device causes the attraction belt to come into contact with and separate from the sheet stack, with different tensions set for the attraction belt at a contact position in contact with the uppermost sheet of the sheet stack and the attraction belt at a separation position separate from the sheet stack.
