Patent number: 10461521Abstract: A driving circuit according to an embodiment includes a driving unit, a first temperature detecting unit, an overheat protecting unit, a second temperature detecting unit, and a failure diagnosing unit. The driving unit supplies a driving current to a load based on a control signal input from a controller. The overheat protecting unit blocks supply of the driving current to the load when the level of the signal output from the first temperature detecting unit exceeds a temperature threshold. The failure diagnosing unit blocks supply of the driving current to the load and outputs a signal of a level corresponding to a temperature out of a temperature range detectable by the second temperature detecting unit to the controller when it is determined that the first temperature detecting unit breaks down.Type: GrantFiled: August 18, 2017Date of Patent: October 29, 2019Assignee: DENSO TEN LimitedInventors: Masayoshi Kume, Motoki Komiya

Patent number: 10107850Abstract: There is provided an abnormality detecting circuit. A clamp unit is configured to clamp an output voltage which is output from another device, such that the upper limit of the output voltage becomes a first clamp voltage which is generated on the basis of a constant voltage generated from a power supply voltage, or a second clamp voltage which is generated on the basis of the power supply voltage and which varies depending on the power supply voltage. A short-to-power detection unit is configured to compare the output voltage clamped by the clamp unit, with a predetermined threshold value which is generated on the basis of the power supply voltage, thereby detecting occurrence of a short to power.Type: GrantFiled: May 18, 2016Date of Patent: October 23, 2018Assignee: FUJITSU TEN LIMITEDInventors: Masayoshi Kume, Keisuke Kido

Patent number: 7482328Abstract: The present invention provides an artificially synthesized antimicrobial polypeptide that does not occur in nature and an antimicrobial agent comprising this polypeptide as the main component. This polypeptide contains in its peptide chain one or more types of nuclear localization signal sequences (NLSs) and/or one or more units of sequences prepared by partially modifying the NLS(s). The one or more units of NLSs and/or modified NLSs contain at least 5 amino acid residues in total and amount to 30% or more of the total amino acid residues constituting the peptide chain.Type: GrantFiled: April 24, 2003Date of Patent: January 27, 2009Assignee: Toagosei Co., Ltd.Inventors: Tetsuhiko Yoshida, Masayoshi Kume, Yoshinao Yamada, Yoko Matsuda, Hiroki Kourai
