Patent number: 8073901Abstract: Information update technique where information held by every apparatus does not need to be updated at the same time. A first server is connected with a second server. The first server judges whether it is possible to access the second server. When a result of the judgment shows that the second server may be accessed, then the first server sends an information update request including information to the second server. On the other hand, when the result of the judgment shows that it is impossible to access the second server, the first server repeats the judgment until it becomes possible to access the second server. When it becomes possible to access the second server, the first server sends an information update request including the information to the second server. Receiving the information update request, the second server updates its information by replacing the information with new information, i.e. the information included in the information update request.Type: GrantFiled: June 27, 2008Date of Patent: December 6, 2011Assignee: Hitachi, Ltd.Inventor: Tetsuya Uemura

Patent number: 8071025Abstract: An automatic analyzer having a smaller size, allowing a larger number of reagents to be loaded, and having a higher processing capability. Reagent disks are disposed inside and outside a reaction disk. Reagent probes are disposed to be able to suck reagents from the reagent disks and eject the reagents at common positions. A plurality of reagent probes are alternately accessed one by one to each of the reagent disks per cycle. Each reagent probe comprises two arms rotatable independently of each other so that the reagent probe is able to access a plurality of points and interference between the plurality of reagent probes can be avoided. A first reagent and a second reagent can be loaded on each of the reagent disks, and the number of loadable reagents can be increased without enlarging an overall system size. Thus, an automatic analyzer having a shorter cycle time and a higher processing capability can be realized.Type: GrantFiled: September 9, 2005Date of Patent: December 6, 2011Assignee: Hitachi High-Technologies CorporationInventors: Hitoshi Tokieda, Isao Yamazaki, Masaaki Hanawa

Publication number: 20110291009Abstract: Disclosed is a device capable of probing with minimal effect from electron beams. Rough probing is made possible using a lower magnification than the magnification usually viewed. When target contact of semiconductor is detected, measurement position is set in the center of picture usually to move probe without moving stage. With the miniaturization, contact can be confirmed only at high magnification, although probe can be confirmed at low magnification on the contrary but it is necessary to display it in real time. Static image obtained at high magnification once is combined with image obtained at low magnification in real time from target contact required for probing and characteristic of probe to be displayed, so that probing at low magnification can be realized to reduce the effects of electron beams and obtain accurate electrical characteristics.Type: ApplicationFiled: January 20, 2010Publication date: December 1, 2011Applicant: Hitachi High-Technologies CorporationInventors: Tohru Ando, Masahiro Sasajima
