Title: Manufacture of glass substrate for liquid crystal display panel
Inventor: KATAUE SATORU
IPC: G02F1/1333
Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To suppress generation or scatter of glass powder and to prevent generation of defective products by breaking mother glass along a scribe line into plural glass substrates and moving each separated glass substrate in a horizontal direction. SOLUTION: Mother glass is broken from its upper surface by a sueegee along a scribe line to obtain plural glass substrates 11. While grasping a glass substrate 11 to be separated by a chuck 18, the substrate 11 is moved about 1 to 2 mm from another glass substrate 11 in parallel. Then a moving means 17 is lifted to move the substrate 11 upward. Since the glass substrate 11 formed by breaking the mother glass by the squeegee along the scribe line is not directly lifted in the vertical direction, generation of fine glass powder due to rubbing of cross sections can be prevented. Since the glass substrate 11 is moved in the horizontal direction, generation of defective products due to the scatter of glass powder sticking to broken cross sections to the upper surface of its adjacent glass substrate 11 can be prevented.

Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To provide an oscillation circuit where a rise time of oscillation upon application of power is short, and an oscillation is maintained with reduced power consumption during steady-state operation is settled. SOLUTION: A counting means 60 is reset at the time of application of a power supply and a control signal CONT is set to 'L'.
