Title: Belt unit
Inventor: MORIGAMI YUSUKE
IPC: B65G15/42
Filed: 2000-01-07
Abstract: PROBLEM TO BE SOLVED: To provide a belt unit capable of effectively preventing meandering of a belt, avoiding effect of a meandering force to a driving roller, and applying a stable belt turning performance. SOLUTION: The driving roller 8 for driving the belt 2 is separated from meandering movement regulating surfaces 2a, 21a of the belt 2, and there is a driving state in which a driven roller 3 and the regulating surfaces 2a, 21a of the belt 2 are slid. When the belt 2 meanders, the driven roller 3 side receives the meandering force to suppress the meandering. Additionally, the meandering force does not act to the driving roller 8. Therefore, even when the meandering force increases, vibration or rotation irregularity does not occur in the driving roller 8 and the belt 2 turns stably.

Title: Horizontal amplitude control circuit
Inventor: KASHIWAGI SHIGERU
IPC: G09G1/00
Filed: 2000-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a horizontal amplitude control circuit wherein the distortion of a picture due to high voltage load variation is slight, a power loss is low, constitution is very simple and the cost is low. SOLUTION: Concerning a pulse Vm1 generated at the connecting point of a capacitor 18 and diodes 19 and 20, the voltage level of the pulse base is clamped to the regulated voltage (a second DC voltage) Ec. When the voltage Ec is increased, the top part of the pulse Vm1 comes into a shape sliced at the level of DC power voltage Eb and a correction pulse Vm also reduces its pulse peak value with the increase of the voltage Ec. Since the pulse peak value of a deflecting current Iy is proportional to the difference between two pulses (Vc-Vm), the horizontal amplitude of an image screen raster spreads wider with the increase of the voltage Ec.
