20150099391 | ELECTRIC CONNECTOR - An electric connector includes a first housing including a guide shaft and a second housing including a guide hole into which the guide shaft is inserted, the guide shaft including a main body, and a projection radially projecting from the main body, the guide hole being formed at an inner surface thereof with a groove into which the projection is fit, the projection and the groove being formed such that a first imaginary line intersects with a second imaginary line, the first imaginary line being defined by extending a contact plane at which the projection and the groove make contact with each other when the first housing rotates relative to the second housing, towards a center of the main body, the second imaginary line being defined as a line bisecting a top surface of the projection and extending towards a center of the main body. | 04-09-2015 |
20150140853 | ELECTRIC CONNECTOR AND DETECTION TERMINAL INCLUDED THEREIN - An electric connector includes a housing to be fit into a second electric connector, a lock arm resiliently deforming when the lock arm makes contact with an engagement part of the second electric connector, and thereafter, returning back to its original position, when the electric connector and the second electric connector are coupled to each other, a first detection terminal for detecting whether the electric connector and the second electric connector are electrically connected to each other, and a unit for assisting the lock arm to return back to the original position, the lock arm, the first detection terminal, and the unit being arranged in the housing, the detection terminal including a first portion to be fixed relative to the lock arm, and a second portion to make contact with a second detection terminal of the second electric connector. | 05-21-2015 |
20150180156 | CASING FOR ELECTRIC CONNECTOR - A casing in which an electric connector is housed, including a floor, and a wall standing perpendicular to the floor, the wall being formed with an opening, when a part of the electric connector projects outwardly through the opening, a seal formed around the part making close contact with an inner edge of the opening, the casing further including a first positioning unit for positioning the electric connector relative to the opening in a first direction defined as a length-wise direction of the wall, and a second positioning unit for positioning the electric connector relative to the opening in a height-wise direction of the wall. | 06-25-2015 |
20150180157 | CASING FOR ELECTRIC CONNECTOR - A casing in which an electric connector is housed, including a floor, and at least one wall standing perpendicularly to the floor, wherein the wall is formed with an opening, when a part of the electric connector projects outwardly through the opening, a seal formed around the part makes close contact with an inner edge of the opening, the casing further including a pair of guide paths allowing the electric connector at opposite ends thereof located in a first direction to slide towards the opening from inside of the casing on a first surface with which the electric connector makes contact at a lower surface thereof, the first direction being defined as a length-wise direction of the wall. | 06-25-2015 |
20150180159 | SEAL USED FOR ELECTRIC CONNECTOR AND METHOD OF USING THE SAME - A seal used for an electric connector having a part protruding outwardly through a first opening formed at a wall of a casing, the seal filling a space formed between an outer surface of the part and an inner surface of the first opening, includes a flat portion formed with a second opening having an inner edge entirely or partially identical in shape with an inner edge of the first opening, the flat portion lying on the wall such that the second opening overlaps the first opening, and a packing portion extending from the flat portion, and making close contact with both the outer surface of the part and the inner surface of the first opening. | 06-25-2015 |

20100182807 | Synchronous Rectifier Circuit Capable of Preventing Flow-Through Current - A synchronous rectifier circuit (DC-DC converter) includes a CR integration circuit and a discharge circuit. The CR integration circuit outputs a voltage that varies at delayed timing as compared with a voltage induced in a secondary-side main winding. The discharge circuit discharges a gate voltage of a rectifier transistor as a result of conduction of a discharge transistor in response to the output voltage from the CR integration circuit. According to such a configuration, the rectifier transistor is turned off earlier than the timing of switching of polarity of voltages induced in the secondary-side main winding and a secondary-side auxiliary winding in response to turn-on of a primary-side transistor. | 07-22-2010 |
20100214810 | Push-Pull Inverter - A push-pull inverter allows a power supply unit to supply an input voltage to two primary windings of a transformer, and allows MOSFETs (Metal Oxide Semiconductor Field Effect Transistors) to drive the transformer in push-pull mode so as to increase the input voltage supplied from the power supply unit and to output the increased voltage as an output voltage from a secondary winding of the transformer. The two primary windings of the transformer are mixedly wound on a same bobbin without being separated, so that when the transformer is driven, the two primary windings of the transformer are prevented from resonating with each other. This makes it possible to prevent turbulence in the input current, thereby reducing loss (power loss) of the MOSFETs, allowing the transformer to have a high efficiency. | 08-26-2010 |
20140078680 | Power Supply Device and Display Device - This power supply device includes a substrate, a transformer mounted on a first surface of the substrate, and a switch element electrically connected to the transformer, mounted on a second surface of the substrate, while the switch element is arranged in a position different from a position on the second surface corresponding to a position on the first surface in which the transformer is mounted. | 03-20-2014 |
20140218977 | SWITCHING POWER SUPPLY CIRCUIT - A switching power supply circuit includes a switching element that switches power fed to a primary winding of a transformer and thus induces a voltage in the secondary winding, and an oscillation circuit that oscillates to generate a pulse signal to control switching action. The oscillation circuit repeatedly performs intermittent oscillation of the pulse signal, and in each of the intermittent oscillation cycles, increases or decreases the number of pulses in the pulse signal to lengthen or shorten the oscillating portion of the pulse signal, and at the time of lengthening or shortening, the oscillation circuit respectively lengthens or shortens an oscillation-halted portion, thus varying the period of the intermittent oscillation cycles. | 08-07-2014 |
