Abstract: The present invention relates to a method for producing pancreatic progenitor cells from pluripotent stem cells. More specifically, the present invention relates to a method for producing pancreatic progenitor cells, comprising causing the action of a factor having the inhibitory activity for cyclin-dependent kinase 8 and/or cyclin-dependent kinase 19 (hereinafter, also abbreviated to CDK8/19).

Abstract: An electronic cash register includes a keyboard having data input keys and a registration complete key, and a memory into which input data is stored by operating the data input keys. The input data of the memory is read out by a central processing unit and printed onto a sheet in a printing section. The cash register further includes a flag memory for storing a flag and a time keeping circuit into which present time data is set, the above-mentioned flag indicating a time period elapsing from an operation of the registration complete key to the start of a next registration operation. When the flag of the flag memory does not indicate the above-mentioned time period, i.e. a registering operation is being effected, an operation other than the registering operation, such as a present time display operation or an alarm operation, is inhibited. When the flag of the flag memory indicates the above-mentioned time period, a present time display operation or an alarm operation is permitted.
