摘要： PROBLEM TO BE SOLVED: To transmit a reception signal even if noise is superimposed on a power supply line, when the power supply line to supply power to a receiver is commonly used in transmission of the received signal from the receiver.
SOLUTION: In a signal shaper circuit 40 provided between a VICS antenna 28, which receives a VICS signal and outputs reception input data signal, and a navigation CPU 62 for signal processing, a low pass filter of a resistor 56 and a capacitor 58 is provided. The cutoff frequency of the low pass filter is set to pass light modulation noise which is generated as a result of turning on/off a current to be applied to an LED 22 and included in the input data signal but cut off the input data signal, which is higher in frequency than the light modulation noise. The input data signal is compared with the filter-processed signal used as a reference signal by a comparator 60. As a result, a final output data signal is outputted in a waveform-shaped form and without loss of data.

摘要： PROBLEM TO BE SOLVED: To provide a power supply unit which, while further holding down costs, reduces the effects of leakage flux from a transformer more than conventionally possible before supplying electric power to external apparatuses.SOLUTION: In a power supply unit 10 comprising a first substrate 12 where at least switching elements Q1 to Q3 (semiconductor elements) are disposed, a transformer 13, a filter mechanism to reduce AC components (a filter section 15 and an output stabilization section 16), and a case 11 which houses the first substrate 12, the transformer 13 and the filter mechanism, there is included a first shielding section 11c, installed between the transformer 13 and the filter mechanism disposed adjacent to each other, which provides protection against noise including leakage flux from the transformer 13. According to this composition, since the first shielding section 11c is interposed, influences exerted upon the filter mechanism by noise including leakage flux from the transformer 13 are reduced. Unlike in the conventional technology, an expensive heat sink can be dispensed with, and costs can therefore be reduced further than possible before.

摘要： PROBLEM TO BE SOLVED: To provide a light emitting diode driving circuit suppressing inrush current causing generation of dimming noise of a light emitting diode with a simple circuit configuration. SOLUTION: An integration circuit 40 is formed in a connection line for connecting a gate terminal of a MOS transistor 33 to gate terminals of MOS transistors 31a-31d. Thereby, even when the gate voltage of the MOS transistor 33 instantaneously changes from an off-voltage to an on-voltage, the gate voltage Vg of the MOS transistors 31a-31d gently rises from an off-voltage to an on-voltage. Thereby, carried currents ILED carried to light emitting diodes 30 by the MOS transistors 31a-31d gradually increase up to certain currents as well instead of instantaneously carrying the certain currents in starting the current carrying. As a result, since it is not necessary to instantaneously carry a large current when release of a current IL from a choke coil 21 is started, generation of inrush current can be suppressed.

摘要翻译：要解决的问题：提供一种抑制浪涌电流的发光二极管驱动电路，其以简单的电路配置引起发光二极管的调光噪声的产生。解决方案：在用于将MOS晶体管33的栅极端子连接到MOS晶体管31a-31d的栅极端子的连接线中形成积分电路40。因此，即使当MOS晶体管33的栅极电压瞬间从截止电压变为导通电压时，MOS晶体管31a-31d的栅极电压Vg从断开电压缓缓上升到导通电压。由此，由MOS晶体管31a-31d承载到发光二极管30的承载电流ILED也逐渐增加到一定的电流，而不是在开始载流时瞬间携带某些电流。结果，由于当开始从扼流线圈21释放电流IL时不需要瞬时携带大电流，因此可以抑制浪涌电流的产生。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a light emitting diode drive circuit capable of protecting a light emitting diode against overheating with high precision. SOLUTION: A constant current IL is made to flow to the light emitting diode 20a through a constant current setting control block equipped with a constant current source, and then a forward voltage detecting circuit unit 300 can detects a forward voltage Vf with high precision. When a voltage corresponding to the forward voltage Vf becomes smaller than a reference voltage Vref, the constant current IL (Va/Ri) determined by a resistance value Ri of the current setting resistance 30 and the voltage Va is made to flow to the light emitting diode 20a. In this case, the constant current IL also decreases as the Va drops, so overheating of the light emitting diode 20a can be suppressed. COPYRIGHT: (C)2009,JPO&INPIT
