Title: Method for holding edge of fused glass flow and apparatus for forming glass ribbon
Inventor: IGA GENICHI
IPC: C03B18/04
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To lessen the occurrence of distortion by compensating the force to spread fused glass flow toward its transverse direction or the force to narrow the fused glass flow by varying the level of the molten metal near the edge of the fused glass flow from the level in the central part and holding the edge of the fused glass flow at a prescribed position. SOLUTION: The fused glass flow 1 of a viscosity of 10<3> to 10<7> poises is passed and dropped onto the molten metal 2 and is supplied to an edge holding part. Next, a linear motor 5 is operated to generate the flow 6 of the molten metal 2 heading toward a ribbon side part 8 from near the edge of the fused glass flow 1 in a trough 3, by which the downward flow 8 of the molten metal 2 is generated in the edge holding part and a negative pressure is generated and the height of the bath surface level 2a of the molten metal 2 in the edge holding part is made lower than the height of the bath surface level 2b of the circumference.  The fused glass flow 1 is admitted into the lowered part to make the thickness of the edge part 1a larger than the thickness in the central part, by which the compressive force occurring in the surface tension of the glass is compensated and the edge is held in the prescribed position.

The AND of the output of the circuits 11 and 15 is taken at an AND16, and is delayed at a monostable multivibrator 17, and the width of a correction pulse is decided at a monostable multivibrator 18. The output passing through a signal processing part 22 is inputted to the X side of a switch 20 and is delayed at a delay circuit 19 until reproducing output at a white side is stabilized, then it is inputted to the Y side of the switch 20. When an E signal is set, the output is connected to the X side, and it becomes a sigal H, and is added on a signal from the processing part 22 at a MIX circuit 23. Thus, it is possible to correct the omission of an edge part lost by the clipping.

Abstract: PURPOSE:To transmit only once an information code and the contents of information from a center to plural terminals by registering an information name and a terminal number to be transferred from the terminals to the center and allowing the center to form a secret code from them to store the code in the terminals. CONSTITUTION:When the terminal number and the information name to be transferred are inputted from an input section 5 of a terminal 1, a control section 6 transmits them to an information center 4 via a transmission and receiving section 8.

When the number is coincident with the terminal number stored in a memory 9, the terminal 1 stores the secret code in a secret code memory 10. When requested information is generated, the center 4 transmits its information code and the information itself. When the number operated from the information code and the own terminal number is coincident with the secret code stored in the memory 10, the terminal outputs the contents of information to an output section 7. Then, the requested data is received by each terminal by transmitting the identical information to the plural terminals only once from the center.
