Patent number: 9628306Abstract: Provided is a pulse generation device capable of suitably adjusting and outputting a pulse pattern by a simple configuration. A pulse generation device (100) includes a radio frequency oscillator (110) that generates a carrier wave of a certain frequency, a baseband pulse generating unit (120) that generates a signal having a certain pulse shape at a baseband, a timing generator (130) that controls a timing to generate a pulse through the baseband pulse generating unit (120), and a mixer (140) that modulates the carrier wave output from the radio frequency oscillator (110) using the pulse output from the baseband pulse generating unit (120). The timing generator (130) can adjust a waveform of the pulse output from the baseband pulse generating unit (120).Type: GrantFiled: September 28, 2015Date of Patent: April 18, 2017Assignees: FURUKAWA ELECTRIC CO., LTD, FURUKAWA AUTOMOTIVE SYSTEMS INC.Inventors: Yoshihito Ishida, Yasushi Aoyagi, Kei Takahashi

Patent number: 9223016Abstract: A pulse radar apparatus and a control method therefor are provided that can detect information about a target with a high degree of accuracy by allowing detection of target information at all times and updating a replica signal of a noise signal in order. When the number of sets of distance data n1 is determined to be more than the number of sets of all distance data Nr in step S5, it is determined that target information detection processing is finished, and replica signal generation processing is subsequently performed. The radar function is activated in steps S13, S15, S16, and the noise signal for each distance data is obtained in step S17. Thereafter, in steps S19, S21, S23, the first, second, and third background signals, respectively, are generated, and thereafter, in step S23, a replica signal is generated.Type: GrantFiled: September 23, 2013Date of Patent: December 29, 2015Assignees: FURUKAWA ELECTRIC CO., LTD., FURUKAWA AUTOMOTIVE SYSTEMS INC.Inventors: Kazutaka Kamimura, Yasushi Aoyagi, Yoshihito Ishida

Patent number: 8547273Abstract: The invention provides a pulse radar apparatus, and a control method thereof, that permits to readily downsize and to lower its cost and allows information on an object to be detected in high precision by removing an influence of noise when a gain of a variable gain amplifier is discontinuously changed corresponding to detected distance, with a simple configuration. A variable gain amplifier 135 configured to adjust a gain corresponding to a distance gate is used to be able to detect weak reflected wave from a distant object and to amplify a reflected wave from a short distance with a low gain. An offset noise from the variable gain amplifier 135 is prepared together with interference noise and self-mixing noise in advance as a replica signal of unwanted wave and the replica signal is removed from a baseband signal in detecting the object T.Type: GrantFiled: September 6, 2012Date of Patent: October 1, 2013Assignees: Furukawa Electric Co., Ltd., Furukawa Automotive Systems Inc.Inventors: Yasushi Aoyagi, Kazutaka Kamimura, Yoshihito Ishida

Publication number: 20110281085Abstract: The objects of the present invention are to provide a polymer thin film having finer structure than the conventional product, excellent regularity over a wide range and only limited defects, patterned media, methods for producing the thin film and patterned media, and surface modifying agent used in these production methods. The method of the present invention is for producing a polymer thin film with a plurality of microdomains regularly arranged in a continuous phase by microphase separation on a substrate, comprising steps for forming a grafted silsesquioxane film on the substrate, and for forming a pattern different in chemical properties from the grafted silsesquioxane film in such a way that the pattern corresponds to the microdomain arrangement.Type: ApplicationFiled: May 12, 2011Publication date: November 17, 2011Inventors: Yasuhiko TADA, Hiroshi Yoshida, Teruaki Hayakawa, Tomoyasu Hirai, Yoshihito Ishida
