Title: Discharge lamp lighting device
Inventor: UCHIHASHI MASAAKI
IPC: H05B41/24
Filed: 1989-11-27
Abstract: PURPOSE:To prevent occurrence of flicker and going out by detecting the mean value of lamp voltage, and by increasing or decreasing on-duty following rising of the lamp voltage in a range where the obtained mean value of the lamp voltage is either lower or higher than the specific value, which is set over the rated voltage of the discharge lamp. CONSTITUTION:A comparator circuit 27 compares a momentary value of lamp current with the output of a lamp voltage detecting circuit 26, which is so set as decreasing with rise of the mean value of the lamp voltage, and the result is used for controlling the on-duty of a switching element. That is, control is so made that the lamp power is increased with rise of the lamp voltage in a range where the lamp voltage is lower than a specific value, which is set over the rated voltage, while the lamp power is decreased with rise of the lamp voltage in a range where the lamp voltage is over the specific value. This prevents the discharge from becoming unstable in the range where the lamp voltage is over the specific value, and also prevents flickering.

Title: Turning mechanism of leaf
Inventor: MATSUMOTO HITOSHI
IPC: B42D9/04
Filed: 1988-12-07
Abstract: PURPOSE:To prevent the occurrence of a faulty turn due to folding of a leaf by moving a passbook by rotating a roller while holding a movable panel by a holding means. CONSTITUTION:When a roller 81 is rotated in the direction of an arrow for turning a leaf, the leaf is curved and thereby a movable panel 9 is pushed and rotated upward. When curving of the leaf increases and the leaf is sprung up above the roller 81 at last, it is detected by a detecting means 10 that the leaf is sprung up, and based on a detection output of the means, a holding means 11 holds the movable panel 9 at a position whereat the leaf is not pressed on the roller 81 by the movable panel 9 under its own weight, i.e. at a position whereat the panel is held above the roller 81 at a prescribed space therefrom. In this state rollers 81 and 82 are rotated to move a passbook 5 in the direction of turning the leaf. Since the leaf sprung up is not pressed on the roller 81 by the movable panel 9 under its own weight, it does not happen that the leaf is folded, the occurrence of an error in turning can be prevented, and thus the leaf can be turned in a stable manner.
