Patent number: 11789013Abstract: Application of the present invention enables quantification of fractions of candidate pharmaceutical compounds (a parent compound and its metabolites), one excreted to the basolateral (Basal/Basolateral)-side via transporters and by diffusion, one excreted to the lumen (Apical)-side, and one remained in the cells. This enables determination of the total amount of the administered candidate pharmaceutical compounds and the distribution ratio of the fractions. The kinetics of the administered candidate pharmaceutical compounds can be evaluated, thereby enabling in vitro screening of an enormous number of candidate pharmaceutical compounds for drug candidates exhibiting the efficacy.Type: GrantFiled: April 23, 2020Date of Patent: October 17, 2023Assignee: Hitachi High-Tech CorporationInventors: Ryosuke Takahashi, Katsuhiro Kanda, Yusuke Shimizu, Hisashi Ichikawa

Publication number: 20160265584Abstract: A ball joint includes a ball seat for slidably holding a ball part of a ball stud. In the ball seat, a stud-side holder is housed in a housing of a socket while the stud-side holder is tilted and deformed to the ball part side by a tapered part. A first groove is formed in the stud-side holder of a holder of the ball seat. The first groove has an only shape with the curvature of the inner surface of the cross-section being a finite value, in other words, has a shape in which a shape with the curvature of the inner surface being an infinite value is not included. The first groove has a shape in which the first derivation value of the distance between the central axis of the tubular holder and the inner surface of the first groove consecutively changes.Type: ApplicationFiled: October 6, 2014Publication date: September 15, 2016Inventors: Hisashi Ichikawa, Hiroaki Ito

Patent number: 4135413Abstract: A device or arrangement of parts for electrically loading a movable member so as to bias same in one direction. In this device, an elastic member is secured to a pivot provided on a base member, with its two arms being deflected and then held by first and second locking members, after which a movable member is forced down against the elastic member from above, so that a guide portion of the movable member may push one arm of the elastic member so as to keep the arm apart from the locking member which locks the arm, and then a locking portion continuous with the guide portion, of the movable member locks the arm. As a result, the movable member is elastically loaded so as to bias in one direction, while the movement of the movable member is limited by means of a control member provided on the base member.Type: GrantFiled: September 28, 1977Date of Patent: January 23, 1979Assignee: Hitachi, Ltd.Inventors: Hisashi Ichikawa, Kenji Ogiro
