Patent number: 8581984Abstract: An analog-state video signal is inputted from each of several in-vehicle cameras via a corresponding signal cable. An amendment amount for making uniform signal levels of the analog-state video signals originating from the respective in-vehicle cameras is determined, with respect to each of the analog-state video signals, based on a burst signal included in each analog-state video signal. According to the determined amendment amounts, the analog-state video signals are amplified to make uniform the signal levels, obtaining analog-state uniformed video signals, respectively. A composite image of combining images originating from the in-vehicle cameras is generated based on the obtained analog-state uniformed video signals.Type: GrantFiled: December 21, 2010Date of Patent: November 12, 2013Assignee: DENSO CORPORATIONInventor: Toshiaki Yamamoto

Patent number: 7521031Abstract: A method for treating exhaust gas includes: adsorbing target components in the exhaust gas with an adsorbent (5); introducing a nitrogen gas with an oxygen concentration of 10 vol % or less and a purity of 90 vol % or more into the adsorbent (5); and applying (6, 7, 8) nonthermal plasma to the adsorbent (5). After the adsorbent (5) adsorbs the target components in the exhaust gas, the nitrogen gas is introduced into the adsorbent (5), and then an electric discharge is generated so that the nonthermal plasma of the nitrogen gas is applied to the adsorbent (5) and causes desorption of the target components and regeneration of the adsorbent (5). This method can remove the target components effectively from oxygen-containing exhaust gas by using nitrogen gas plasma with high activity as a result of ionization of a nitrogen gas and combining adsorption, desorption by the nitrogen gas plasma, and nitrogen plasma treatment.Type: GrantFiled: October 6, 2004Date of Patent: April 21, 2009Assignee: Osaka Industrial Promotion OrganizationInventors: Masaaki Okubo, Toshiaki Yamamoto, Tomoyuki Kuroki
