Publication number: 20230323475Abstract: The diagnostic markers that provide novel diagnostic criteria to blastic plasmacytoid dendritic cell neoplasm (BPDCN) has been searched, and the presence of immunoblastoid cytomorphology, 8q24 rearrangement, and MYC expression were established as novel markers for subtyping BPDCN. It has been further found that the inhibitors which directly or indirectly inhibit the expression, functions, or signaling pathways of MYC, such as BET bromodomain-selective inhibitors or aurora kinase inhibitors, are effective in MYC-positive BPDCN, and HDAC inhibitors or BCL2 family protein inhibitors are effective as therapeutic drugs for BPDCN.Type: ApplicationFiled: May 9, 2023Publication date: October 12, 2023Inventors: Kengo Takeuchi, Kana Sakamoto, Ryohei Katayama, Seiji Sakata

Patent number: 5528361Abstract: An image forming apparatus capable of executing a plurality of functions at the same time to promote efficient use thereof. The apparatus includes reading means for reading a document, recording means for forming an image on a sheet, and an operating section for setting modes and displaying information. Control means causes the recording means to print simultaneously and continuously image data read by the reading means and a plurality of independent data written to a memory by a plurality of functions.Type: GrantFiled: March 16, 1993Date of Patent: June 18, 1996Assignee: Ricoh Company, Ltd.Inventor: Seiji Sakata

Patent number: 5251045Abstract: A magnification changing system for a copier. When any one of a document longitudinal key, a document lateral key, a copy longitudinal key and a copy lateral key is pressed, all the data associated with that key are displayed so that an operator is clearly informed of whether or not the entry of particular data is requested.Type: GrantFiled: July 13, 1992Date of Patent: October 5, 1993Assignee: Ricoh Company, Ltd.Inventor: Seiji Sakata

Patent number: 5111309Abstract: A digital copier having a density control system. The background of the original document is digitally erased based on the density of the background. The image data is separately controlled and not effected by the background erasing process. A manual operating control is provided in conjunction with an automatic density mode in order to control the image data. The particular level of the image data can be adjusted even in the automatic density mode.Type: GrantFiled: May 21, 1990Date of Patent: May 5, 1992Assignee: Ricoh Company, Ltd.Inventor: Seiji Sakata

Patent number: 5105284Abstract: A digital copier using a laser card or like external storing medium for storing image data. A remaining amount of memory capacity of a laser card is displayed in terms of the number of papers of a particular size or by percent. Based on the remaining amount of capacity, image data are compressed and reduced, the reduction ratio being also recorded in the card. When the contents of a series of documents cannot be accommodated in a single card, the first card is provided with a mark which shows that the second card is to follow.Type: GrantFiled: December 14, 1989Date of Patent: April 14, 1992Assignee: Ricoh Company, Ltd.Inventors: Seiji Sakata, Tamotsu Harada, Norifumi Ito, Masayuki Hayashi, Tsuyoshi Yoshimura, Nobuyuki Koinuma
