Title: Planar display device and manufacturing method therefor
Inventor: ISHIU TAKEHIKO
IPC: G02F1/1368
Filed: 2002-07-11
Abstract: PROBLEM TO BE SOLVED: To provide a planar display device of which the voltage dependency is suppressed. SOLUTION: After an auxiliary capacitance semiconductor layer 37 and then a resist mask are formed, impurity ions are injected into the auxiliary capacitance semiconductor layer 37. The part of the resist altered by injecting the impurity ions is dry-ashed without exposing semiconductor layers 31, 41, 45, and the remaining resist is removed by wet-etching. A gate insulating film 51 is formed after the impurity ions are injected into the auxiliary capacitance semiconductor layer 37 so that no impurities are present in a gate insulating film 51. Since the auxiliary capacitance semiconductor layer 37 of the auxiliary capacitance 24 contains the impurities at a high concentration, a leakage current is lowered to suppress the rate of dot defect generation.  Since no impurities are present in the di-electric layer of the auxiliary capacitance semiconductor layer 37, deterioration in the characteristics of thin film transistors 23 for pixels, thin film transistors 25 for a p-type driving circuit, and thin film transistors 26 for an N-type driving circuit does not occur.

Title: Roll clamp device
Inventor: HIRATA DAISUKE
IPC: B66F9/18
Filed: 2002-07-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide a roll clamp device capable of preventing a clamp arm from scratching and damaging the floor, and from generating loud noises at the time of taking delivery.  <P>SOLUTION: A roller 20 brought into rotatable contact with the floor 19 is rotatably supported on a short arm 14. Since the short arm 14 can be advanced by bringing the roller 20 into rotatable contact with the floor 19, the short arm does not scratch and damage the floor 19. The generated noises turn into the rolling frictional noises of the roller 20 which is remarkably smaller comparing with the frictional noises of a plate and the floor 19. Since the noises become small, an operator can perform the taking delivery work in comfort without giving consideration to the surrounding.  <P>COPYRIGHT: (C)2004,JPO
