The present disclosure relates to an ultrasonic imaging apparatus that has a tolerance for easy assembly and reduces shaking and noise by reducing the tolerance after assembly. The ultrasonic imaging apparatus includes a main body, a probe connected to the main body to irradiate and receive ultrasonic waves and to transmit the ultrasonic signals to the main body, a control panel configured to control the main body or the probe, and a moving device configured to connect the control panel and the main body and to move the control panel with respect to the main body in the upward and downward directions, wherein the moving device includes a housing fixed to the main body, a moving member configured to be movable with respect to the housing in the upward and downward directions, and a regulating bearing installed in the housing and configured to assist the upward and downward movement of the moving member by coming into rolling contact with the moving member and to regulate a gap with the moving member.

Supports utilized to stabilize and/or support parked trailers, such as semitrailers parked at loading docks while loading and/or unloading cargo, are disclosed. Some example embodiments may include jacks mounted to repositionable frames, which may be mounted to posts. Some example embodiments may be configured to engage with king pin plates and/or king pins on the undersides of trailers.

An assembly includes an attachment arm having an axle extending from a first end of the attachment arm. The attachment arm of the detachable wheel assembly further includes a securing portion forming a second end of the attachment arm, the securing portion of the attachment arm including a pin positioned to extend above a first frame member of a gantry truss and to secure the first frame member between the pin and a portion of the attachment arm. The attachment arm also includes a frame support corresponding to a second frame member of the gantry truss such that the frame support supports the second frame member when the assembly is secured to the gantry truss, and the assembly includes a wheel rotatably attached to the axle of the attachment arm.

A wheel/foot assembly for a sign display stand or other object includes a cradle partially enclosing an optional wheel. The assembly is releasably attachable to a leg for a sign display stand, protects the leg and can be easily replaced if worn. The assemble protects wear on the stand and permits the sign display stand to be wheeled, rather than dragged or carried. Because the assembly is releasably attached, it can be replaced easily if damaged or worn.

A fluid balancer includes: a shaft; a cylinder; a base member which includes a through hole through which a shaft is inserted; a spacer which is provided between the shaft and the base member, and includes a plurality of grooves which are formed in a surface opposed to the shaft in the circumferential direction of the shaft at intervals and extend along the axial direction of the shaft and elastic support portion which supports the spacer with respect to the base member.

A photography stand configured to aid in a taking of self or group photograph(s). The photography stand is placed in a visited location where photographs are frequently taken with a background of interest. The photography stand comprises a post, a platform, and a holder configured to hold a camera enabled handheld electronic device. The platform has a top surface that is textured and a bottom surface attaches to a top end of the post. The platform is stationary, but in alternative embodiments, the platform spins at the connection with the post. The stand also can be placed into the ground or can include a base on a bottom end of the post which allows the stand to be placed on the ground. The base may include one or more wheels to move the stand.
