Title: Gene transduction cell sheet
Inventor: UEDA MINORU
IPC: A61K48/00
Filed: 1998-10-21
Abstract: PROBLEM TO BE SOLVED: To provide a gene transduction cell sheet into which an object gene can be readily transduced and can be prepared in a shortened time, particularly obtain a congenic cell sheet that can increase the take percentage to the living body and can produce the product of the introduced gene for a long period of time after the introduction. SOLUTION: This cell sheet is constituted with plural layers of mucosal epithelial cells into which the object gene is transduced. As the mucosal epithelial cells are more anaplastic, the object gene can be easily transduced. For example, in the case that the gene of an antimicrobial peptide is used as the object gene, the gene transduction cell sheet can be inhibited from its infection as a transplant thereby increasing the take percentage. In another case where human blood coagulation factor IX is used as the object gene, the formation of the blood coagulation factor IX can be retained in an organism for a long period of time.

Title: Method for using alloy type temperature fuse
Inventor: NISHIDE RITSU
IPC: H01H37/76
Filed: 1992-10-12
Abstract: PURPOSE:To use identical alloy type temperature fuses at a lower rated voltage as a rated current is higher, and use them at various rated currents. CONSTITUTION:Since a current flowing in a fuse element is increased during temperature fuse operation at various rated current values, Joule heat generation of a fuse becomes large so that a temperature at a cut portion of the fuse is increased and heat dissociation becomes large. Energy of an arc generated at the cut portion becomes large accordingly. When the fuse is used at a lower rated voltage as the rated current is higher, the arc can be weakened accordingly. Consequently, it is possible to avoid an increase in arc energy as a whole.

IPC: G06F12/08
Filed: 1988-11-30
Abstract: PURPOSE:To constitute a cache memory system so that a failure part can be supported easily even when a mounted cache memory device is used as it is by executing an operation test of an information processor by switching an operation mode of the cache memory device. CONSTITUTION:A cache hit/miss deciding circuit 44 decides a normal mode in which a cache memory device 40 operates regularly or a minicache mode for executing an operation only at the time of cache hit by mode information M from a mode register 43. By setting the cache memory device 40 to the minicache mode, a CPU 10 can execute an operation test of an information processor excluding a principal part of the cache memory device 40 in a state that the cache memory device 40 is mounted. Subsequently, after confirming a fact that the device is normal, the operation test of the principal component is executed by setting the cache memory device 40 to the normal mode. In such a way, a failure of the principal part of the device or other failure can be discriminated simply in a state that the cache memory device is mounted.
