Abstract: An atomic beam is quantum-mechanically collimated. The atomic beam is irradiated with a pumping laser beam and a filtering laser beam in this order. The pumping laser beam has a wavelength corresponding to a transition between a ground state and an excited state of atoms in the atomic beam. Irradiation with the pumping laser beam causes atoms to make transition from the ground state to the excited state and further relax from the excited state to a metastable state. The filtering laser beam has a wavelength corresponding to a transition between the ground state and the metastable state. By irradiating the filtering laser beam, atoms in the metastable state having velocity components equal to or smaller than a predetermined velocity component ?v in a traveling direction of the filtering laser beam are caused to make transition to the ground state.

Abstract: A wireless connector is composed of a pair of units. Each unit includes an annular transmission/reception unit which is provided with a coil used to wirelessly transmit electric power, and formed of a plurality of coil parts, and a main connector portion which is detachably attached to an object from the outside of the object to transmit the electric power to the object. Each unit is assembled such that each unit can be divided into a plurality of non-annular pieces so that the coil can be formed by coupling the plurality of coil parts via a plurality of connectors for coil. When one of the transmission/reception units is attached to the object, the one of the transmission/reception units is arranged so as to oppose the other one of the transmission/reception units in a non-contact manner such that electric power can be wirelessly transmitted therebetween.

Abstract: A method for manufacturing a connector comprises providing a housing and a contact intermediate product, making the holding portion of the housing hold a held portion of the contact intermediate product to attach the contact intermediate product to the housing, and inserting a jig between a contact point and the held portion to deform the contact intermediate product plastically and thereby forming a contact. The contact intermediate product does not enter an allowing portion in a state where it is attached to the housing. After the plastically deformation, a tip portion is situated in the allowing portion, and it is hidden by a movement suppression portion at least in part when viewed along an up-down direction.

Abstract: A connector comprises an insert-molded body. The insert-molded body comprises a housing and a terminal partially embedded in the housing. The housing has a main portion. The main portion is formed with a trace hole and an accommodation space. The terminal has a held portion, a bent-back portion extending forward from the held portion, a support portion extending rearward from the bent-back portion and a contact portion supported by the support portion. The held portion has a wide portion. When the insert-molded body is seen from above, the wide portion is, at least in part, visible through the trace hole. Each of the support portion and the contact portion has a size smaller than that of the wide portion in the lateral direction. The wide portion is partially visible through the accommodation space when the insert-molded body is seen from below.

Abstract: A connector is mateable with a mating connector in a front-rear direction. The connector has a main portion which is formed of a multilayer wiring substrate. The multilayer wiring substrate includes a first metal conductive layer and a second metal conductive layer. The second metal conductive layer has two conductive exposed portions. The conductive exposed portions are exposed to an outside of the connector at opposite side surfaces, respectively, of the main portion. The conductive exposed portions correspond to hooks, respectively, of the mating connector. Each of the conductive exposed portions has a thickness greater than a thickness of a lock portion of the corresponding hook of the mating connector. The lock portion of each of the hooks is brought into contact with the corresponding conductive exposed portion when the lock portions lock a mated state where the mating connector and the connector are mated with each other.

Abstract: A lever of a connector can rotate between a first position and a second position and can slide between the second position and a third position. When the lever is rotated to the second position in a state in which the connector whose lever is on the first position is on a fitting preparation position with respect to a mating connector, the connector is drawn to a fitting position, which is closer to the mating connector, by a cam mechanism and a main terminal of the connector and a mating main terminal of the mating connector are connected with each other. When the lever is slid to the third position, a flange portion provided to a housing of the connector and a mating flange portion provided to a mating housing of the mating connector are accommodated in a groove portion of the lever.

Abstract: In a connecting method, when a flexible conductor is exposed on a top surface of a connection object, a contact is disposed on the top surface of the connection object at the predetermined position in a state where the connection object is kept as it is, and when the flexible conductor is exposed on a bottom surface of the connection object, the contact is disposed on the top surface of the connection object at the predetermined position in a state where a part of the connection object where the connection part is disposed is inverted such that the connection part faces a top surface side of the connection object while being retained at the predetermined position.

Abstract: A connector includes a housing and terminals each having a fixation portion, an extension portion, and a connection portion. Each connection portion includes a connecting base portion, a first arm, and a second arm. The first arm includes a support portion and a sub-arm formed of a first sub-arm and a second sub-arm. The first sub-arm has a first contact portion and the second sub-arm has a second contact portion.

Each connection portion is configured such that when a mating connection unit is inserted between the respective first arms and the respective second arms, the pressing portion presses against the mating connection unit and at least either contact portion of the first contact portion and the second contact portion establishes continuity with the mating connection unit.

Abstract: An antenna device comprises a case and an antenna element. The antenna element is arranged in the case and radiates a radio wave with a predetermined frequency which has a plane of polarization in parallel to a predetermined plane. The case is formed with a predetermined opening. The predetermined opening has two main openings and a coupling opening. The two main openings are apart from each other in a first direction perpendicular to the predetermined plane. The coupling opening couples the two main openings together in the first direction. The coupling opening has a size smaller than another size of each of the two main openings in a second direction perpendicular to the first direction. The predetermined opening forms a split ring resonator which resonates at the predetermined frequency and radiates a radio wave corresponding to the radio wave radiated from the antenna element.
