Patent number: 10355100Abstract: A first field effect transistor and a second field effect transistor are formed on a substrate. A silicon nitride liner is formed over the first field effect transistor and the second field effect transistor. An upper portion of the silicon nitride liner is converted into a thermal silicon oxide liner. A lower portion of the silicon nitride liner remains as a silicon nitride material portion. A first portion of the thermal silicon oxide liner is removed from above the second field effect transistor, and a second portion of the thermal silicon oxide liner remains above the first field effect transistor. Selective presence of the silicon oxide liner provides differential stress within the channels of the first and second field effect transistors, which can be employed to optimize performance of different types of field effect transistors.Type: GrantFiled: May 17, 2018Date of Patent: July 16, 2019Assignee: SANDISK TECHNOLOGIES LLCInventors: Yu Ueda, Tomoyuki Obu, Kazutaka Yoshizawa, Yasuyuki Aoki, Eisuke Takii, Akio Nishida

Patent number: 7778941Abstract: A position recognition device for deciding a zone where a moving object takes a position. The device comprises: a travel distance decider for deciding whether or not the moving object has traveled a predetermined distance corresponding to the detection error of the position of the moving object; and a zone decider for deciding the zone where the moving object takes a position, if the travel distance decider decides that the moving object has traveled the predetermined distance. According to the invention, therefore, “the decision of the zone where the moving object exists” is not made, in case the position of the moving object cannot be precisely detected. Therefore, the precision in the decision of the zone where the moving object exists is improved, and it is unnecessary to set a buffer zone that “the decision of the zone where the moving object exists is not made if the moving object takes a position in the neighborhood” as the reference for deciding the existing zone of the moving object.Type: GrantFiled: August 10, 2001Date of Patent: August 17, 2010Assignees: Toyota Jidosha Kabushiki Kaisha, Aisin Seiki Kabushiki KaishaInventors: Masaki Kakihara, Yasuyuki Aoki

Patent number: 7487108Abstract: An on-vehicle automatic charging apparatus 10 obtains its own position information from GPS signals from GPS satellites 51 to 53, determines on the basis of the position information whether conditions for charging are satisfied, and subtracts a calculated charge amount from an inserted prepaid car, when the conditions for charging are satisfied. At this time, information used for calculation of the charge amount is written into the prepaid card as a charge record. When the prepaid card is inserted into a card issuing machine 20 in order to increase the balance, the card issuing machine 20 reads the written charge record and transmits it to a center computer 30. The center computer 30 distributes the charge amount to management companies on the basis of the charge record.Type: GrantFiled: September 28, 2001Date of Patent: February 3, 2009Assignees: Aisin Seiki Kabushiki Kaisha, Toyota Jidosha Kabushiki KaishaInventors: Yasuyuki Aoki, Masaki Kakihara
