Abstract: Provided are an ocular surface drug-retaining agent that enables an excellent improvement in retainability of a medicament on an ocular surface and an eye drop containing the agent. An ocular surface drug-retaining agent containing a copolymer having three different kinds of constituent units at a specific ratio can express an excellent effect of retaining a medicament on an ocular surface (in particular, a corneal surface) to allow the effect or action of the drug to be sustained over a long period of time.

Abstract: The vacuum heat treatment device includes: a guide plate used to guide a cooling medium supplied by a cooling unit, into a heat-insulating container through one of at least two openings of the heat-insulating container in a state where the two openings of the heat-insulating container are opened; and a movement mechanism used to move the guide plate so that at least part of the guide plate is inserted into a movement area of a cover portion in a state where the two openings of the heat-insulating container are opened and so that the guide plate is retracted from the movement area of the cover portion before the cover portion is moved in order to close the two openings of the heat-insulating container.

Abstract: A boiler steam amount measuring method for continuously measuring a temporal change in an amount of steam from a steam boiler, includes: first measuring a differential pressure between a pressure at a first detection position that is a predetermined position in a can body of the steam boiler or a steam outflow path, and a pressure at a second detection position in the steam outflow path separated from the first detection position toward a downstream side; first calculating a pressure loss coefficient based on the differential pressure measured by flowing a predetermined flow rate of steam or fluid instead of steam into the steam outflow path, and the predetermined flow rate; and second calculating continuously the amount of steam based on the differential pressure measured in the first measuring and the pressure loss coefficient calculated in the first calculating, and outputting the calculated amount of steam as a measurement value.
