摘要:
A novel human stem cell which can be differentiated to cells constituting a plurality of human organs including human liver is disclosed. The human stem cell according to the present invention is originated from human salivary gland, which is CD49f-positive, and which can be differentiated to (1) a nestin-positive and albumin-positive cell, (2) an insulin-positive cell and (3) a glucagon-positive cell by culture in vitro.

A stem cell which can be differentiated to a hepatic cell, a pancreas cell or to a salivary gland cell is disclosed. The stem cell according to the present invention is originated from salivary gland duct epithelium, which can be differentiated to an alpha-fetoprotein-positive cell, an albumin-positive cell, an amylase-positive cell, an insulin-positive cell and a glucagon-positive cell by culture in vitro. By transplanting the stem cells according to the present invention, organs such as liver can be regenerated.

摘要:
Card-type memories have a memory unit with an area having a minimum memory capacity and a control unit for interpreting a command issued by a host system and controlling the memory unit in accordance with the command. The memory area is formatted in accordance with the universal disk format so each sector of the area has a user data area of 2048 bytes with a logical sector length of 2048 bytes. File management is performed by a UDF file system of a host computer.

A piezoelectric power generating device includes a power generating element and a package member. The power generating element includes a plate-like piezoelectric element and a metal plate. The piezoelectric element has a pair of principal surfaces opposite each other. The metal plate is bonded to one of the principal surfaces of the piezoelectric element. The package member has a supporting part and a restricting part. The supporting part supports an end of the power generating element in a cantilevered manner. The restricting part is disposed opposite the piezoelectric element with the metal plate interposed therebetween. The restricting part restricts displacement of the power generating element toward the outside of the metal plate.

摘要:
A USB storage device having the function of preventing stored software from being deleted by mistake achieved with as simple a structure as possible. In the USB storage device, the storage area is divided into an area in which execution of reading, writing and deleting is allowed and an area in which only execution of reading is allowed. Information to make a USB mass storage class driver recognize these areas as areas corresponding, respectively, to logical unit numbers defined in the SCSI command set of the USB mass storage class driver owned by the host is stored in the USB storage device. The information includes logical unit numbers, formats, writing/deleting allowed/not allowed flag, logical block numbers and physical block numbers. By this, the USB mass storage class driver recognizes the USB storage device as a SCSI device having two logical units.
