Abstract: A fetal-pulse-wave-velocity-related-information obtaining apparatus, including a heartbeat-synchronous-signal detecting device at least a portion of which is adapted to be worn on at least one of a fetus and a mother so as to detect a heartbeat-synchronous signal produced from a proximal portion of the fetus; a pulse-wave detecting device which detects a pulse wave from a distal portion of the fetus that is located on a distal side of the proximal portion of the fetus; and a pulse-wave-velocity-related-information obtaining device for iteratively obtaining, based on the heartbeat-synchronous signal detected by the heartbeat-synchronous-signal detecting device and the pulse wave detected by the pulse-wave detecting device, respective sets of pulse-wave-velocity-related information each of which is related to a velocity at which the pulse wave propagates in the fetus.

Abstract: A furnace for cooling molten glass, which comprises a cooling tank for slowly cooling the molten glass while the average temperature of the molten glass is within a certain range extending below and above the temperature at which the speed of absorbing bubbles is highest, and cooling it rapidly when the average temperature of the molten glass is outside said range.
