摘要:
The present invention relates to a cytoplasmic transduction peptide (CTP) showing transduction potential, as well as cytoplasmic remaining potential and various uses thereof. The CTP of this invention exhibits a transduction potential identical or higher than the conventional protein transduction, PTD, and a strong tendency to remain in the cytoplasm, so that it is very useful in inducing cytotoxic T lymphocytes (CTL) and a drug delivery system (DDS) targeting cytoplasm.
摘要:
In an exemplary embodiment of the invention a method of forming a gate oxide layer of a semiconductor device uses deuterium gas. The method includes introducing a semiconductor substrate, and depositing an insulating layer on the semiconductor substrate by supplying an oxidation reaction gas and a deuterium gas to the semiconductor substrate. Thus, a high quality gate oxide layer can be formed and resistance to degradation from the hot carrier effect can be improved. Further, when the method is applied to a tunnel oxide layer process of a flash memory, problems such as an increasing dispersion of the threshold voltage can be mitigated.
摘要:
A cleaning device of a charging unit in an image forming apparatus using an electrophotographic process for cleaning a corona wire. The cleaning device comprises an elongated shield case having a guide slit in a central portion extending in a lengthwise direction of a photosensitive drum; a cleaning shaft guide containing a bore therein, mounted to the guide slit and adapted to slide along the guide slit, a cleaning shaft having a handle and an integrally connected body inserted into the bore and adapted to maintain a cleaning member at a distance from the corona wire during non-cleaning of the corona wire, and to allow, upon application of force, the cleaning member to resiliently press against the corona wire and move along the corona wire while being held in frictional contact with the corona wire during cleaning of the corona wire by way of an elastic spring disposed between the handle of the cleaning shaft and the cleaning shaft guide.
