Abstract: The ultrasonic probe has an element part which transmits and receives ultrasonic waves, a relay cable connected to the element part, which transmits a signal to the element part, a frame and a window constituting a housing part in which the element part and the relay cable are housed, and an oscillation mechanism which oscillates the element part. The oscillation mechanism has a rotation axis configured to provide oscillation movement of the element part. The relay cable has an S-shape or a reversed S-shape with two arc-shaped parts. One end of the relay cable is connected to a cable connecting surface of the element part and, when the element part is positioned at a middle of a scanning range, in a connected portion with the element part, the relay cable is drawn from a point connected to the element part in a direction substantially parallel to the cable connecting surface. The frame is placed on an opposite side of the rotation axis from the element part.

Abstract: In an ultrasonic probe including an element part 1 for transmitting and receiving ultrasonic waves, a relay cable 2 connected to the element part 1 and an oscillation mechanism part for oscillating the element part, a cross section of the relay cable 2, which is taken perpendicularly to a rotation axis 3 of the oscillation that is provided to the element part 1 by the oscillation mechanism part, has at least two arc-shaped parts smoothly connected each other, more specifically, S-shape arc-shaped parts or reversed S-shaped parts. In addition, the relay cable 2 is drawn from the surface of the element part 1 facing the rotation axis 3. In this manner, the stress applied to the relay cable 2 during the oscillation of the element part 1 can be dispersed, thereby improving durability of the relay cable 2.

Abstract: The invention provides a security design device that, even when a core configuration element implementing a security function has become unusable, enables maintenance of security that existed before the loss of the core configuration element. The security design device: in correspondence with a configuration change of a first configuration element, extracts a security requirement model; and if the first configuration element is the core configuration element, for a second configuration element for which the security function was implemented by means of the first configuration element, generates the security requirement model without using the first configuration element, said security requirement model implementing the same security function as when the first configuration is used.

Abstract: A bite-in type pipe joint includes a first joint member having an internal thread and a second joint member having an external thread. An annular ferrule is formed integrally with the second joint member. By the time the first and second joint members are fastened to each other, the ferrule separates from the second joint member and bites into a pipe. The second joint member has a cylindrical cover that covers the ferrule. This structure prevents a distal portion and a tapered surface of the ferrule from being damaged when the joint member is handled. A refrigerating apparatus and/or a water heating device can include one or more of the pipe joints.
