Abstract: PURPOSE:To prevent the abnormal operation of a microcomputer to hold data in an RAM by monitoring always a battery voltage and resetting the microcomputer before the battery voltage becomes too lower to obtain the normal operating voltage of the microcomputer. CONSTITUTION:A comparing circuit 1 compares a battery voltage VB with a set voltage VS, and the output goes to the high level in case of VB>=VS and goes to the low level in case of VB<VS and is connected to the input side of an off delay timer circuit 2, and the output side of the circuit 2 is connected to a microcomputer 3. The output of the circuit 2 goes to the low level when the output of the comparing circuit 1 goes to the low level, and the output of the circuit 2 goes to the high level after a prescribed time when the output of the circuit 1 goes to the high level. A regulator 4 adjusts the input voltage to 5V to apply a power source voltage VC to the microcomputer 3. When the battery voltage is lower (<=5.5V indicated by A in the figure), runaway of the microcomputer 3 is prevented because the microcomputer 3 is reset. Further, since reset of the microomputer 3 is released after a prescribed time T when the battery voltage VB is restored to >=5.5V, the microcomputer 3 is restarted stably.

Title: Glass fusion furnace
Inventor: HANADO SHINJI
IPC: C03B5/027
Filed: 1993-06-30
Abstract: PURPOSE:To enhance the operational efficiency by disposing an upper electrode in the vicinity of the liquid level of a fused material and accelerating the heating in the vicinity of the glass material dropping surface and at the low temperature part thereby making uniform the inner temperature of a fusion tank. CONSTITUTION:An upper electrode 12 is disposed at the inclining part on the side wall 2 of a fusion tank 11 having constricted upper part while exposing the surface thereof along the inclination of the side wall 2. Since a glass material is thrown into the fusion tank 11 through a material supply port 7, a low temperature part or a cold trap may occur in the vicinity of the surface of fused material X when power is not fed to the electrode 12. When power is fed to the electrode 12, the function for increasing the upper current distribution through inclination of the electrode 12 is offset by the function for retarding the current flow through low temperature in the vicinity of the liquid level, RL, thus making uniform the current distribution between the pair of electrodes 12 and allowing uniform heating. Since the glass material is fused quickly to bring about the fused state over the entire inner region of the fusion tank 12, operational efficiency is enhanced.
