Abstract: The present invention relates to a bioabsorbable sheet or film, composed of a composition containing phosphorylated pullulan. The bioabsorbable sheet or film of the present invention can be suitably used in the medical fields, for example, as medical adhesives to be patched to a biotissue such as organs and blood vessels during surgical operations.

Abstract: A liquid transfer method includes the steps of conveying a sheet by holding the sheet by a transport cylinder, and transferring a liquid to one surface of the sheet by a transfer cylinder opposing the transport cylinder and transferring the liquid to the other surface of the sheet by the transport cylinder. The step of transferring includes the step of positioning an edge of a region on one surface of the sheet, downstream in a sheet convey direction, where the liquid is to be transferred, upstream in the sheet convey direction of an edge of a region on the other surface of the sheet, downstream in the sheet convey direction, where the liquid is to be transferred. A liquid transfer apparatus is also disclosed.

Abstract: A liquid transfer apparatus includes a supply cylinder and viscosity reducing agent supply unit. The supply cylinder comes into contact with a transfer target body and supplies a transfer liquid to the transfer target body. The viscosity reducing agent supply unit supplies a viscosity reducing agent which reduces a viscosity of the transfer liquid to the supply cylinder after the apparatus emergently stops and before the supply cylinder starts transfer.

Abstract: A cleaning apparatus includes a first liquid supply unit, second cylinder, cleaning unit, third cylinder, second liquid supply unit, first cleaning liquid supply unit, and controller. The first liquid supply unit supplies a transfer liquid to a first cylinder. The second cylinder performs transfer to one surface of a transfer target body with the transfer liquid transferred from the first cylinder. The cleaning unit cleans the circumferential surface of the second cylinder in contact with it. The third cylinder is arranged to oppose the second cylinder and performs transfer to the other surface of the transfer target body. The second liquid supply unit supplies the transfer liquid to the third cylinder. The first cleaning liquid supply unit supplies a cleaning liquid to at least one of the first cylinder and the third cylinder. The controller controls the control unit to clean the second cylinder while the second cylinder is in contact with the first cylinder and the third cylinder.

Abstract: A cleaning apparatus includes a liquid supply device and cleaning unit. The liquid supply device supplies a transfer liquid to a first cylinder. The transfer liquid supplied from the liquid supply device to the first cylinder is transferred to a transfer target body which comes into contact with the first cylinder. The cleaning unit comes into contact with and cleans the first cylinder. The cleaning unit is arranged downstream of a contact position where the first cylinder is in contact with the transfer target body in a rotational direction of the first cylinder, and upstream of a liquid receiving position where the first cylinder receives a liquid supplied from the liquid supply device in a rotational direction of the first cylinder.

Abstract: A cleaning apparatus includes a cleaning web, contact member, and web travel unit. The cleaning web is supported to be able to come into contact with and separate from a rotating body so as to clean the rotating body. The contact member comes into contact with the cleaning web. The web travel unit causes the cleaning web to travel and causes the cleaning web to travel for a predetermined length after cleaning the rotating body.
