|20130278056||DC Power Supply System and Control Method - A DC power supply system and a control method, which can continue charging of a storage battery with a constant current even if an assist current is needed due to, for example, overload during charging of the storage battery and can suppress a current output from the storage battery as much as possible. In a power supply system, when a charger operates at a potential of an output voltage smaller than the potential of the output voltage of a rectifier during charging of the storage battery, the output current of the charger is controlled so that a charging current Ie supplied from the charger to the storage battery is kept at a predetermined value, and when a load requires a current larger than the current supplied by the rectifier during charging of the storage battery, the potential of the output voltage of the rectifier is reduced smaller than the potential of the output voltage of the charger by a current drooping operation, and the diode is electrically connected, the output current of the charger is controlled so that the charger outputs the assistant current Ic supplied toward the load while the charging current Ie is kept at a predetermined value.||10-24-2013|
|20130231007||CONNECTOR AND SWITCH - There is provided a connector including a connection terminal to be connected to another connection terminal of another connector; a fixed contact; a movable contact provided on one button end portion of a movable plate; a card made of an insulating material and being in contact with the movable plate; a button in contact with the card; a swing spring connected to the button; and a slide operating portion for controlling a contact between the fixed contact and the movable contact, wherein one of the fixed contact and the movable contact is connected to the connection terminal, the button is pushed down by moving the slide operating portion in one direction to thereby move the movable plate via the card, the connector is in a turn-on state when the fixed contact is in contact with the movable contact, the swing spring generates restoring force in a direction of separating a contact between the fixed contact and the movable contact, and the movable contact is separated from the fixed contact so as to be in a turn-off state the connector by moving the slide operating portion in another direction opposite to the one direction.||09-05-2013|
|20120258638||CONNECTOR AND CONNECTOR SET - A connector etc. that prevents wrong insertion and does not require large rotation of plug etc., when inserting a plug to a socket, is provided. Plug-in connector||10-11-2012|
|20120131862||DOUBLE FLOOR STRUCTURE AND SUPPORT LEG FOR DOUBLE FLOOR STRUCTURE - A double floor structure capable of being adapted to the conditions of construction and the needs of users at low cost. A double floor structure (K) provided with support legs (||05-31-2012|
|20110117762||CONNECTOR DEVICE, RECEIVING CONNECTOR, AND INSERTING CONNECTOR - A connector device includes an inserting connector and a receiving connector, wherein the receiving connector is connected to the electronic device; the receiving connector includes a single control plug terminal and two electric power jack terminals made of a conductor material, the electric power jack terminals being configured to receive the supply of the electric power; the control plug terminal can be extended and retracted in an inserting direction of the receiving connector; the inserting connector is connected to the electric power source; the inserting connector includes a control jack terminal corresponding to the control plug terminal and two electric power plug terminals corresponding to the two electric power jack terminals; and the control jack terminal includes a control switch.||05-19-2011|
|20110117758||A CONNECTOR UNIT WITH A MALE CONNECTOR HAVING A CONTROL TERMINAL WITH A SWITCH - A connector unit includes a male connector including a control plug terminal, a slide switch for moving the control plug terminal between a first position and a second position in a first direction, a return button protruding from the opening of the slide switch in a second direction perpendicular to the first direction, an urging part to urge the return button in the second direction, and an elastic member; and a female connector including a control jack terminal including a control switch. The control plug terminal is moved to the first position to connect the contacts of the control switch. The return button is pressed with the control plug terminal at the first position to cause the elastic member to deform via the control plug terminal, so that the control plug terminal is moved to the second position with the restoring force of the elastic member.||05-19-2011|
