Title: Light source lighting device and illumination system
Inventor: ITO YUICHIRO
IPC: H05B37/02
Filed: 2009-11-06
Abstract: <P>PROBLEM TO BE SOLVED: To turn off a switching element of a step-down chopper by detecting an overcurrent instantly, while conducting a feed-back controlling of an LED current suitably by a simple circuit construction.  <P>SOLUTION: The LED lighting device includes: an LED 11 connected with an output of a step-down chopper circuit 32; an LED current-detecting resistor 12 for detecting an LED current; a differential amplifier 14 for detecting a voltage difference at both ends of the LED current-detecting resistor 12; a second switching element-controlling circuit 17 which compares an output signal of an error amplifier 15 with a target signal and adjusts an ON period of the second switching element 7 of the step-down chopper circuit 32 in a direction to match a signal level; and a switching current-detecting resistor 13 for detecting a current flowing in the second switching element 7 of the step-down chopper circuit 32. The second switching element-controlling circuit 17 turns off the second switching element 7 of the step-down chopper circuit 32 when a current flowing in the switching current-detecting resistor 13 becomes a prescribed current or more.  <P>COPYRIGHT: (C)2011,JPO&INPIT

Title: Abnormal condition detection device of booster negative pressure sensor
Inventor: TOMITA KOUICHI
IPC: B60T17/00
Filed: 2009-11-06
Abstract: <P>PROBLEM TO BE SOLVED: To improve reliability in an abnormality detection result of a booster negative pressure sensor.  <P>SOLUTION: When an engine negative pressure estimate value is in a steady state, and when a detection value of the booster negative pressure sensor is larger than an abnormal condition determining threshold value, a determination is temporarily made that the booster negative pressure sensor is abnormal (B2). When the engine negative pressure estimate value increases (a two-dot chain line) until a preset time Th<SB>11</SB>passes, a temporary abnormal condition detection result is canceled. Since the engine negative pressure estimate value changes delayed in a change from an actual value of engine negative pressure, when temporarily detected as an abnormal condition, the actual engine negative pressure increases, so that the possibility of being erroneously detected as abnormal is high due to its increase. The reliability of an abnormal condition detection result of the booster negative pressure sensor can be improved thereby.  <P>COPYRIGHT: (C)2011,JPO&INPIT

Filed: 2009-11-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a potentiality advantage in cost for measuring distance with high time accuracy in accordance with light transit time principle.  <P>SOLUTION: A division cycle of a frequency f1=400 MHz or a frequency f2=410 MHz is formed of a master cycle of 10 MHz. In order to produce an optional magnification of a differential cycle, a time base unit selects a pair formed of an n-th period of the frequency f2 and an m-th period of the frequency f1. The position of each pair is fixed to the master cycle, for example, n=2 and m=6 correspond to the time interval of 4/f2+6ΔT, and 1/f2=41ΔT. In this case, a counter is reset whenever 100 ns passes and synchronism occurs, and the numbering of the pair starts from the beginning. Based on the two frequencies f1 and f2, the time base extremely narrower than a detection segment can be used.  <P>COPYRIGHT: (C)2010,JPO&INPIT
