Title: Lighting device for discharge lamp
Inventor: YAMADA AKIYASU
IPC: H05B41/24
Filed: 1994-09-16
Abstract: PURPOSE: To enable a filament to be sufficiently preheated by a circuit simple in constitution by connecting an electrolytic capacitor at the low voltage side of a partial smoothing circuit to its high voltage side, and thereby letting oscillation be started at low voltage by a switching element at the time of starting. CONSTITUTION: At the time of starting, the voltage across a Zener diode 2 is lower than a Zener voltage, and both a transistor 3 and a switching element 4 are turned off. In this case, oscillation transistors 5 and 6 allows oscillation to be started at voltage at both ends of an electrolytic capacitor 1 at the low voltage side of a partial smoothing circuit. Therefore, a lamp is not lit because of low voltage, and is brought into a continuous preheating condition, so that its filament is sufficiently preheated. After a specified period of time has elapsed, when voltage across the diode 2 exceeds the Zener voltage, the clipped transistor 3 is turned on, and the element 4 is also driven so as to be turned on. This situation thereby allows oscillation to be started at high voltage, and thereby enables the lamp to be reasonably lit.

Title: Method and device for detecting motion vector
Inventor: MASUYA KEN
IPC: H04N19/85
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To reduce erroneous detection of a motion vector by detecting a zero vector without fail even when an input signal is affected by jitter or the like. SOLUTION: A differential value operating part 52 finds a differential value DFD between a reference field signal and a deviated field signal. A gradient value operating part 50 finds gradient quantity between the adjacent picture elements of the reference field as an absolute value |ΔX| and a code SIGNΔX. A multiplier 54 multiplies the DFD and the SIGNΔX. An accumulating part 56 outputs a value ΣSIGNΔX.DFD for which the result is accumulated for picture elements of a block. An accumulating part 58 outputs a value Σ|ΔX|for which |ΔX| is accumulated for the number of picture elements in a block.  When the zero vector is selected as an initial deviated vector, a comparative value selecting part 60 sets a comparative value α0 to a discrimination part 62 but when any vector excepting for the zero vector is selected, a comparative value α1 (α0>α1) is set to the discrimination part 62. According to the discriminated result, a vector operating part 64 outputs the zero vector or a deviated vector Vx operated from the results of the accumulating parts 56 and 58.
