20080203163 | Manual noncontact IC card reader - A technology that is applicable generally to manual noncontact card readers regardless of whether they are of insertion or swipe type, and realizes stable communication even with antennas of small size is provided. A pair of loop antennas | 08-28-2008 |
20090039160 | Card processor - In a card processor having a function of intermittently transporting a magnetic card, card information is prevented more effectively from being illegally acquired by a skimmer mounted on a card slot. Transport rollers are mounted near the card slot. When a sensor turns ON as a card is inserted into the card slot, the transport rollers are intermittently driven to intermittently transport the card and fetch it in the card processor. Since the card is intermittently transported approximately at the same time when the card is inserted, even if a skimmer SK is mounted on the card slot, information skimmed with a magnetic head H of the skimmer SK during card insertion is only little information in a range a, and most of information will not be skimmed. | 02-12-2009 |

20100131222 | PHYSICAL QUANTITY MEASUREMENT DEVICE - The physical quantity measurement device involves a terminal unit, a sensor, a storage unit, an output unit, a communication unit, a control unit, and a discriminating unit. The terminal unit has a power terminal, an output terminal, and a ground terminal. The communication unit uses the power terminal in order to receive a serial signal from an external device. The control unit has an adjusting mode and a normal mode. The discriminating unit decides that the external device requests either the adjusting mode or the normal mode based on whether or not an electrical potential of each of the power terminal and the output terminal satisfies a predetermined condition. The control unit selects the normal mode when the discriminating unit decides that the external device requests the normal mode, and selects the adjusting mode when the discriminating unit decides that the external device request the adjusting mode. | 05-27-2010 |

20120243272 | CONSTANT CURRENT POWER SUPPLY APPARATUS - A constant current power supply apparatus is provided which can drive a load with a constant current, even if the circuit configuration is such that a time delay is generated in the feedback control of a converter, or the like. An FB period restricting circuit including an ON generation circuit, OR circuit, inverter, and PMOS restricts the period during which an FB signal is fed back, to the logical sum of the ON period of an SW signal for driving an LED array on and a replenishment period generated by the OR circuit based on the SW signal. An FB signal generation circuit including a differential amplifier, NMOS, reference voltage, capacitor, and shunt regulator generates, in the replenishment period other than the ON period of the SW signal, an FB signal corresponding to an output current having flown through the LED array during the ON period of the SW signal. | 09-27-2012 |
20140347895 | Switching Power-Supply Device - A switching power-supply device includes a COMP-voltage comparator circuit that compares a COMP-voltage obtained by performing phase compensation on the feedback signal, with a first threshold voltage which is a threshold value; and an intermittent-oscillation control circuit that, if it is detected by the COMP-voltage comparator circuit that the COMP-voltage is lower than the first threshold voltage, stops the switching operation of the switching device and performs a transition to a first intermittent oscillation operation in which the switching device performs the switching operation every predetermined first period, wherein if a predetermined delay period elapses in a state where the COMP-voltage is lower than the first threshold voltage, the intermittent-oscillation control circuit performs a transition to a second intermittent oscillation operation in which the switching device performs the switching operation every second period which is an integral multiple of the first period. | 11-27-2014 |
