摘要:
An ink jet printing apparatus is provided that can realize a stable ejection volume with the minimum change in a voltage value supplied in a scanning. To realize this, when a detected temperature of a print head is included in a first range, a pulse width control is performed while a voltage being fixed to a first voltage. When a detected temperature is included in a second range, a pulse width control is performed while a voltage being fixed to a second voltage. In the pulse width control based on the two voltages, a temperature partially overlapped region is provided between the first range and the second range. By this, even when a print head has an increased temperature during a print scanning, an ejection volume can be controlled, in the print scanning, while minimizing the switching of a driving voltage.
摘要:
A packaged tea beverage contains from 0.06 to 0.5 wt % of non-polymer catechins and an artificial sweetener. The content weight ratio (A)/(B) of (A) non-epicatechins to (B) epicatechins is from 0.54 to 9.0. This beverage is a highly clear packaged tea beverage, which contains catechins at a high concentration, makes the deterioration of catechins suppressed, is suited for long-term drinking, hardly changes in external appearance even during storage at a high temperature, and allows catechins to remain stable over a long term even when filled and stored in a clear package.
摘要:
An ink jet recording apparatus for effecting recording using a recording head for ejecting ink, the ink jet recording apparatus includes heating means for heating the recording head; detecting means for detecting a temperature of the recording head; setting means for setting a target temperature of the recording head, control means for controlling the target temperature of the recording head at or above a target temperature; wherein the control means controls the temperature by heating control for heating the recording head and by diffusing control for diffusing the heat supplied by the heating control.
