Title: Fluorescent lamp electronic lighting device
Inventor: KUMAGAI MIKIO
IPC: H05B41/18
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To provide a fluorescent lamp electronic lighting device for protecting the deterioration or breakage of a thyrister in the terminal stage of the life of a fluorescent lamp by arranging a voltage dividing circuit and a charge/ discharge circuit in a non-power source side circuit of the fluorescent lamp. SOLUTION: In the terminal stage of the life of a fluorescent lamp, the peak value of lamp voltage for causing discharge is increased, and movement to the discharge state becomes difficult. A thyrister repeats retriggers, preheating current intermittently flows, and the power loss of the thyrister is increased to lead to breakage. While the thyrister Thy repeats triggers, charge to a first capacitor C2 proceeds, and finally, charge current is stopped to flow and the trigger of the thyrister Thy stops. By the stop of lighting operation, the power loss of the thyrister Thy caused by preheating current is prevented, and the thyrister Thy can be protected from deterioration or breakage.

Then, garbage is thrown in onto the inside lid parts 4b and the foot pedal is released, and the lid bodies 4 are turned downward by their self-weight and the inside lid parts 4b are opened, so that the garbage drops in the inside of the garbage box. At the same time, the end edges of the outer lid parts 4a are brought into contact with each other so as to close the garbage inlet 3.

Abstract: PURPOSE:To facilitate postprocessing by an operator by providing an abnormal electrostatic discharging detecting means, a decision means, and an abnormality postprocessing means which performs postprocessing by judging that a normal image forming process is not performed at the time of deciding that the decision means exerts an influence. CONSTITUTION:A sequencer 21 has a function for deciding whether or not the detection signal of an overcurrent detecting circuit 14 which is supplied through an input/output circuit 22 affects an image area in terms of timing by using the time table of a predetermined image formation process and whether or not abnormal discharging has energy large enough to affect an image from the output time (pulse width) of the detection signal. When it is decided that the influence is exerted in both cases, a control command for the postprocessing is outputted. Consequently, even if abnormal discharging occurs in a process of large-quantity copying operation, the postprocessing by the operator is facilitated and an easy-to-operate copying machine is obtained.

Abstract: PURPOSE:To form a P-type gate electrode for a P-channel MOSFET and to form an N-type gate electrode for an N-channel type MOSFET without effects on characteristics by selectively growing a polycrystalline silicon film incorporating P-type or N-type impurities, and forming the gate electrodes. CONSTITUTION:An undoped polycrystalline silicon film or a polycrystalline silicon film doped at 1X10<19>cm<-3> or less is formed on a gate insulating film. Then, a P-type polycrystalline silicon film is selectively formed on the polycrystalline silicon film in a P-channel type MOSFET forming region. An N-type polycrystalline silicon film is selectively formed on the polycrystalline silicon film in an N-channel type MOSFET forming region. Thereafter, gate electrodes are patterned.

Abstract: PURPOSE:To quickly stop before generation of next pulse without increasing power consumption by providing a stopping mechanism to be applied by a load to stop a printer, if necessary, in synchronization with a timing pulse generated upon rotation of a type wheel shaft. CONSTITUTION:A cam 5-a is provided at a print gear 5 rotated synchronously with a print unit 6, and a motor stop spring 4 engaged at one side with the cam 5-a and at the other with a motor gear 1-a to rotate at a reduction gear shaft 3 fixed to a frame 2 as a center is provided.
