The present invention provides a system 10 for irradiating a breast 20 of a patient 22. The system 10 comprises a gantry 12 rotatable about a horizontal axis 14 and comprising a radiation source 16 for generating a radiation beam 18 and a detector 24 spaced from the radiation source 16, and a barrier 26 disposed between the patient 22 and the gantry 12. The barrier 26 is provided with an opening 30 adapted to allow a breast 20 passing therethrough to be exposed to the radiation beam 18. In some embodiments, the barrier 26 is provided with an opening 30 adapted to allow both the breast 20 and the tissue leading from the breast to axilla and the muscle tissue of the adjacent chest wall passing therethrough to be exposed to the radiation beam 18.

Electrochemical method for treating teeth: applying metal salt solution to teeth, applying ionizable substance to the teeth, and applying current flow to the teeth so as to ionize the ionizable substance. Electrochemical device for dental treatment: applicator for applying a substance to teeth, having a first end and a second end, a first electrode attached to first end of applicator, second electrode attached to second end of applicator, wherein first electrode and second electrode are configured for current flow through applicator, and an ionizable substance for placement within applicator, wherein ionizable substance is configured for ionization upon application of current flow through the substance. Electrochemical teeth whitening method: applying metal salt solution to teeth, applying an oxidizing agent to teeth exposed to metal salt solution, and applying current flow to the teeth so as to activate and reduce the oxidizing agent for effecting whitening of the teeth.

A contact terminal includes: a contact pin; and a plate spring configured to support the contact pin, wherein a portion of the plate spring is connected to a circuit board, wherein the contact pin can be connected to a counterpart while being supported by the plate spring, thus ensuring a stable connection structure.

A method and apparatus of circulating cavitation fluid within a cavitation fluid circulatory system is provided. The system provides a means of circulating the cavitation fluid through a cavitation chamber, before or during cavitation chamber operation, as well as a means of draining and filling the chamber with minimal, if any, exposure of the cavitation fluid to the outside environment. The apparatus includes a network of conduits coupling the cavitation chamber to a cavitation fluid reservoir and at least one external fluid pump. Preferably the cavitation fluid reservoir serves the dual function of fluid reservoir and degassing chamber. Manipulation of various valves within the conduit network allows the cavitation fluid to either be pumped from the reservoir into the cavitation chamber or from the cavitation chamber into the reservoir. During cavitation chamber operation, the same pump and conduit network can be used to continuously or intermittently circulate the cavitation fluid through the degassing system. A vacuum pump coupled to the degassing system can operate continuously or intermittently during system degassing. In another aspect, the cavitation fluid circulation system includes a bubble trap immediately following the fluid pump, thus providing a means of capturing bubbles generated during the pumping operation. In yet another aspect, the cavitation fluid circulation system includes a filter, preferably for removing contaminants that could disrupt the cavitation process. In yet another aspect, the cavitation fluid circulation system includes a heat exchange system, thus allowing the temperature of the cavitation fluid to be controlled.

A mammography apparatus capable of obtaining a breast image having an optimum density with reduced burden on the subject. The apparatus includes a radiation irradiation section and an object table connected to an arm such that they face each other, and the breast compressed onto the object table using a compression paddle is imaged by rotating the arm by an arm rotation means according to the imaging direction. In the apparatus, the size of the breast is detected, and the position of a dose detector is moved along the side of the object table facing the chestwall of the subject according to the detected size of the breast and the angle of rotation of the arm when rotated by the arm rotation means.

A valve manifold assembly including a manifold body defining a primary flow passage and a secondary flow passage fluidly coupled therewith through an aperture in the wall of the primary flow passage. A valve including a head portion and a stem extending therefrom is disposed through the aperture. The head portion has a valve sealing surface adjacent and extending around the stem, and a valve seat having a seat sealing surface facing into the primary flow passage extends around the aperture. The valve is selectively shiftable between a closed position wherein the valve sealing surface is sealingly engaged with the seat sealing surface to block fluid flow between the secondary flow passage and the primary flow passage, and an open position wherein the valve sealing surface is spaced apart from the seat sealing surface to enable fluid flow between the secondary flow passage and the primary flow passage.

A contact terminal includes: a contact pin; and a plate spring configured to support the contact pin, wherein a portion of the plate spring is connected to a circuit board, wherein the contact pin can be connected to a counterpart while being supported by the plate spring, thus ensuring a stable connection structure.

Clothing includes a body part, a waistband part circumferentially provided at an upper end of the body part and having opposite end portions, and a rubber band encapsulated in the waistband part. Locking units are provided on a surface of the end portion and a back face of the end portion, opposite ends of the rubber band which can be exposed from a side end of the end portion and from a hole portion formed in the back face of the end portion are coupled by a coupling unit so that a length of the rubber band can be adjusted, the opening / closing portions integral with the opposite end portions can be separated leftward and rightward, and the units are invisible from the front when the opening / closing portions are closed. Therefore, clothing with a waist size, which can be adjusted by a wearer, and with good appearance can be provided.

Getter multilayer structures are disclosed, embodiments of which include at least a layer of a non-evaporable getter alloy having a low activation temperature over a layer of a different non-evaporable getter material having high specific surface area, both preferably obtained by cathodic deposition. The multilayer NEG structures exhibit better gas sorbing characteristics and lower activation temperature lower than those of deposits made up of a single material. A process for manufacturing such structures includes depositing a first, high surface area NEG film on a support, and then depositing a thin over layer of low activation NEG film.
