20140117891 | SEMICONDUCTOR DEVICE, ELECTRONIC APPLIANCE, AND VEHICLE - A semiconductor device has a first chip and a second chip sealed in a single package. The first chip includes a regulator which generates an internal voltage from a supply voltage, a reset circuit which monitors the supply voltage and the internal voltage to generate a reset signal, and a controlled circuit which operates by being supplied with the supply voltage. The second chip includes a controlling circuit which generates a control signal for the controlled circuit by being supplied with the internal voltage. The reset signal is fed to both the controlling circuit and the controlled circuit. | 05-01-2014 |
20150079914 | ANTENNA DRIVING DEVICE - An antenna driving device includes an antenna driving circuit arranged to generate driving current of a transmission antenna, a power supply circuit arranged to generate an output voltage from an input voltage so as to supply the output voltage to the antenna driving circuit, and a logic circuit arranged to control the antenna driving circuit and the power supply circuit. The power supply circuit has a function of temporarily disabling current feedback control so as to perform voltage feedback control using a reference value just before halting the drive of the transmission antenna when the power supply circuit restarts to drive the transmission antenna, or has a function of performing variable control of a reference value for current feedback control in accordance with a rising edge of the driving current when the power supply circuit restarts to drive the transmission antenna. | 03-19-2015 |

20080271556 | ROTATION DRIVE UNIT AND IMAGE FORMING APPARATUS USING SAME - A rotation drive unit having a first reduction mechanism of traction transmission system comprising a drive roller attached to a drive shaft and a driven roller attached to a driven shaft, and a second reduction mechanism of gear transmission system comprising a drive gear attached to the drive shaft and a driven gear attached to the driven shaft. The first reduction mechanism generates a braking effort while making slippage between the rollers during transmission of a rotational driving force from the drive shaft, and exerts a torque load on the second reduction mechanism of the gear transmission system. Since this unit transmits the rotational driving force via the first reduction mechanism while exerting the load upon the second reduction mechanism, it provides a satisfactory and reliable speed-reducing function as well as reliable and accurate transmission of the rotational driving force even if equipped with a plurality of driven shafts coupled to the single drive shaft. The rotation drive unit is suitable for driving photoconductor drums of an image forming apparatus. The rotation drive unit thus provides a sufficient speed-reducing function while effectively avoiding the need to increase a size of the apparatus even in a structure having a plurality of driven members. | 11-06-2008 |

20110273104 | CONTROL CIRCUIT FOR SWITCHING POWER SUPPLY - A control IC controls a switching power supply configured to supply a driving voltage Vout to one terminal of an LED string which is driven in an intermittent manner. A sample-and-hold circuit performs sampling of a detection voltage Vs that corresponds to a driving voltage Vout in the on period, and holds the sampled detection voltage Vs in the off period. In the off period, a pulse modulator generates a pulse signal having a duty ratio adjusted such that a hold detection voltage VsH output from the sample-and-hold circuit matches the detection voltage Vs. A driver drives a switching transistor according to the pulse signal. | 11-10-2011 |

20150109632 | ELECTRONIC DEVICE - An electronic device includes a first mode, a second mode, a mode transition accepting unit, a state confirmation unit, and a transition determination unit. The mode transition accepting unit is configured to accept from a plurality of demanding sources a transition demand to transition from the first mode to the second mode. The state confirmation unit is configured to confirm a device state of the electronic device. The transition determination unit is configured to determine whether or not a transition from the first mode to the second mode is possible based on a demanding source of the transition demand accepted by the mode transition accepting unit, and the device state confirmed by the state confirmation unit. When the device state is a predetermined device state, the transition determination unit makes a determination that the transition is possible for some of the plurality of demanding sources that issued the transition demand and not possible for others of the plurality of demanding sources that issued the transition demand. | 04-23-2015 |
