Abstract: A method for monitoring thoracic tissue. The method comprises intercepting reflections of electromagnetic (EM) radiation reflected from thoracic tissue of a patient in radiation sessions during a period of at least 24 hours, detecting a change of a dielectric coefficient of the thoracic tissue by analyzing respective the reflections, and outputting a notification indicating the change. The reflections are changed as an outcome of thoracic movements which occur during the period.

Abstract: A reactor-securing structure includes, one end of a first-side stay and one end of a second-side stay that are connected to portions of a reactor which are separated from each other at the two sides of a coil axial direction. The other end of the first-side stay and the other end of the second-side stay are fastened in states overlapping the inverter case. A first-side overlapping portion is formed by having the other end of the first-side stay overlap the inverter case, and a second-side overlapping portion is formed by having the other end of the second-side stay overlap the inverter case. A portion of the first-side overlapping portion and a portion of the second-side overlapping portion, when seen from a plan view, are provided in the same range relating to the length direction of the I-shaped section forming the reactor.

Abstract: A toroidal core choke includes a toroidal core and an insulating part. The insulating part includes a separating device for separating winding spaces on the toroidal core. The separating device includes a divider and a spacer on an end of the divider. A width of the divider is less than a width of the spacer.

Abstract: A press-button switch is provided which includes a control unit between a press button and a conductive switching element within a housing of the press-button switch. The control unit utilizes a push element and a hook member beneath the press button to push and pull, respectively, against a first and a second actuating element both of which are situated at different planes. Thus, the rotary body of the control unit can continuously rotate at an angle of 180 degrees in a single direction, and the eccentric hole will change its position between an upper point (H) and a lower point (L) in order to move the push-pull rod for displacing the switching element for the on-off control. Moreover, the press-button switch can be smoothly disconnected in off state for ensuring the electric safety in case of overload current.

Abstract: An inverter transformer is formed of first and second cores arranged to face each other to form a closed magnetic circuit. The first core has a central leg, an outer perimeter wall, and a partition between the central leg and the outer perimeter wall so that a first groove is formed between the central leg and the partition and a second groove is formed between the partition and the outer perimeter wall concentrically with and outside the first groove. A primary winding is disposed in the second groove, and a secondary winding is disposed in the first groove so that the primary and secondary windings are arranged in the same plane.

Abstract: Groups of magnets are respectively provided on the joint surfaces of a vehicle-side connector and a power-supply-side connector in such a way that the N and S poles of a plurality of permanent magnets are alternately arranged in a circle. When charging is carried out, the magnetic attraction generated by placing the heteropolar magnets in both groups of magnets opposite to one another is utilized for bringing the vehicle-side connector and the power-supply-side connector into engagement with each other. After the charging, the group of magnets of the power-supply-side connector are turned by one pitch to place the homopolar magnets in both groups of magnets opposite to one another, whereby both connectors are easily separated from each other because of the magnetic repulsive force generated therebetween.

Abstract: An electromagnetic coupling device for charging an electric motor vehicle is provided which is easy for handling a charging coupler and hardly lowers electric power transmission efficiency for a long period of time. A charging coupler (10) containing a primary coil (15) is provided with a pair of heat-shielding covers (16), which are pivotably mounted on the coupler (10) by pins (17). When the charging coupler (10) is inserted into a depression (31) in an incoming unit of the electric motor vehicle, guides (21) push lower ends (16a) of the covers (16) to open the covers (16). The primary coil (15) in the charging coupler (10) is electromagnetically coupled to a pair of secondary coils (32, 32) in the depression (31). After charging, when the charging coupler (10) is drawn out of the depression (31), the heat-shielding covers (16) are closed by tension coil springs (18), thereby protecting the primary coil (15) and preventing a person from carelessly touching it.

Abstract: An inductive coupler for use in a battery charging system for an electric vehicle has a primary device having a primary coil and a core and a secondary device having a secondary coil and core. The primary and secondary devices are coupleable together with the primary coil placed within an open space defined by the secondary coil. The secondary coil is formed and sized so as to have a greater dimension than the primary coil as measured in the longitudinal direction of an electric vehicle parked for battery charging so that a space interval between the two coils in the longitudinal direction of the vehicle is greater than that in the lateral direction of the vehicle.

Abstract: A separable inductive coupler for transferring electrical power across a dielectric medium using magnetic induction. Its coil geometry allows for easy disassembly of primary and secondary circuits. When primary and secondary coils are mated, an extremely low leakage inductance transformer is formed. This provides for good high frequency operation at high power density. The coupler allows electrical power transfer without metal-to-metal contact. The design allows easy removal of the primary or secondary coil from the transformer. The coil geometry has very low leakage inductance and very low high-frequency resistance which allows high frequency operation. The power transfer density is much higher than previously achieved with separable inductive couplers. Approximately 6000 watts has been transferred through a version of the present separable inductive coupler having a volume of 25.8 cubic inches, yielding a power density of 230 Watts/cubic inch.

In particular, it is adapted for the medical treatment of living animal tissue by hyperthermia. The electrode comprises a single loop turn having capacitance associated therewith so as to resonate the electrode for maximum power transfer thereto. The electrode causes a field to be generated within the annular region enclosed by the electrode comprising a plurality of concentric, substantially equally powered lines of force in which the living tissue to be treated is disposed. The electrode finds particular use in the treatment of deep seated cancers in patients.

Abstract: An apparatus and method for coupling electromagnetic energy into a dielectric material such as tissue while substantially reducing external leakage of the energy. The apparatus may also be used as a receiver for electromagnetic energy transmitted through tissue. The apparatus includes an open transmission line which is inherently non-radiating and may be configurated with a centrally disposed, central strip conductor. A ground plane conductor is placed in spaced relationship to the central strip conductor and on both sides of the central strip conductor. Alternatively, the central strip conductor may be placed in spaced relationship to one side of a ground plane conductor. The central strip conductor is terminated with a resistor of resistance equal to the characteristic impedance of the open transmission line.
