It is determined that indoor condensation of hydrogen peroxide vapor is to occur, if there is a solution with which both (Equation 1): PT·y1=P01·x1·γ1 and (Equation 2): PT·y2=P02·x2·γ2 hold. With this, it is possible to accurately determine whether indoor condensation of hydrogen peroxide vapor is to occur or not in decontamination.

In an image processing apparatus that includes an order placement means for executing an operation associated with order placement of an expendable used in an image forming apparatus, data associated with image formation is accumulated to have a timing associated with order placement as a trigger, and the operation of the order placement means is controlled on the basis of the accumulated value. In this manner, redundant orders for expendables can be prevented.

A semiconductor device comprises: a p-type semiconductor substrate (1); an insulating film (3); a gate electrode (2) formed an the substrate via the insulating film; and an n-type source/drain region (5) formed on both sides of a channel forming region (4) located under the gate electrode (2) formed on the substrate (1). In particular, the thickness (TOX) of the insulating film (3) is determined to be less than 2.5 nm at conversion rate of silicon oxide film (silicon oxide equivalent thickness); a gate length (Lg) of the gate electrode (2) is determined to be equal to or less than 0.3 μm; and further a voltage applied to the gate electrode (2) and the drain region (6) is determined a be 1.5 V or less. Therefore, in the MOSFET having the tunneling gate oxide film (3), the reliability of the transistor under the hot carrier stress can be improved, and the gate leakage current can be reduced markedly, so that the transistor characteristics can be improved markedly.

The present invention provides materials from laver (a seaweed) as the starting material, which are useful in the field of pharmaceutical preparation, the field of health food, etc. The present invention relates to enzyme-decomposed materials from laver comprising a peptide mixture having an antihypertensive action obtained by decomposing laver with pepsin, wherein laver is boiled as a starting material for 1 hour or more and then the broth is removed whereby their antihypertensive action is further raised while their bitter taste, smell, viscosity etc. are eliminated. Accordingly, these enzyme-decomposed materials are made further useful as an antihypertensive agent and also suitable when added to food for use as health food. Further, these materials after decomposed with pepsin are further decomposed with an enzyme having a peptidase activity thereby improving tastes and providing more suitable food additives.
