Method for crystal growth of multi-element oxide thin film containing bismuth as constituent element
Patent number: 6071338Abstract: A method for crystal growth of a multi-element oxide thin film containing bismuth as a constituent element has setting a growth environment to fall under conditions such that an oxide of bismuth alone will not be formed, but the desired multi-element oxide will be formed; and supplying bismuth in excess of other elements to the growth environment, to prevent the lack of bismuth and evaporate surplus bismuth from the thin film. This method suppresses the formation of different phases or the precipitation of impurities ascribed to the deviation of the proportion of bismuth element from the desired composition, enables a high quality thin film to be grown, and markedly broadens the ranges of the set conditions for the thin film growth temperature and oxidizing gas in comparison with conventional technologies.Type: GrantFiled: November 25, 1997Date of Patent: June 6, 2000Assignee: Agency of Industrial Science & TechnologyInventors: Shigeki Sakai, Shinji Migita -
Patent number: 5940502Abstract: A phone holder for detachably holding a mobile phone in an automotive vehicle is provided with a holder main body including an inner casing having a phone accommodating portion, a phone urging device having a phone actuating roller and the like for urging the mobile phone being inserted into the phone accommodating portion in a direction opposite from an inserting direction of the mobile phone, and a phone locking device which can be switched between a locking state where the mobile phone is locked in a specified accommodation position in the phone accommodating portion against a urging force of the phone urger and an unlocking state where the locking is released. The phone locking device is switched to the locking state as the mobile phone is inserted into the phone accommodating portion. The above locking is releasable by moving the mobile phone in its locked state in the inserting direction.Type: GrantFiled: December 8, 1997Date of Patent: August 17, 1999Assignees: Harness System Technologies Research, Ltd., Sumitomo Wiring Systems, Ltd., Sumitomo Electric Industries Ltd.Inventors: Hiroki Hirai, Masashi Sugimoto, Shigeki Sakai, Yoshito Sakai, Nori Inoue, Tetsuji Tanaka, Yuichiro Tsutsumi
