Patent number: 10170997Abstract: A PWM signal generation circuit controls a current mode to set a PWM signal to an on-level in synchronization with a dock signal and set the PWM signal to an off-level in synchronization with a normal reset signal, which changes its level when a current detection signal reaches an error signal. A switching determination circuit checks whether an output voltage reached a switching determination voltage higher than a target output voltage. A reset signal generation circuit generates a reset signal, which is delayed by a predetermine time period from a time point of a change of the PWM signal to the on-level. When the switching determination circuit determines that the output voltage reached the switching determination voltage, the PWM signal generation circuit changes the PWM signal to the off-level in synchronization with the reset signal in place of the reset signal.Type: GrantFiled: October 13, 2017Date of Patent: January 1, 2019Assignee: DENSO CORPORATIONInventor: Takashi Asahi

Publication number: 20170209328Abstract: An orthosis 1 includes: an outer layer 2 which maintains a substantially elliptic shape; and a buffer 3 provided on the inner periphery of the outer layer 2, and buffers predetermined sites on the head. When the orthosis 1 is worn deviating from a state where the minor axis of the substantially elliptic shape corresponds to the width of the head, pressers 24a, 24b are formed which press the predetermined sites on the head with a stronger force than a force before deviation. The outer layer 2 includes adjustment portions 23a and 23b which can be close or apart in the minor axis direction of the substantially elliptic shape. The orthosis 1 further includes an adjuster 4 which adjusts the adjustment portions 23a, 23b so that the length of the minor axis of the substantially elliptic shape can correspond to the width of the head.Type: ApplicationFiled: September 28, 2015Publication date: July 27, 2017Inventors: Hiroyuki Kajimoto, Michi Sato, Takeyoshi Iguchi, Takashi Asahi
