Patent number: 9893619Abstract: A DC/DC converter in which a both-end voltage of each of capacitors can be safely uniformalized while an over current, which is passed through between the capacitors composing the DC/DC converter, is prevented. In a DC/DC converter which includes a plurality of switching elements, a reactor, a low-voltage side capacitor, a high-voltage side capacitor, a charge-discharge capacitor, and a controller which drives and controls the switching elements, the controller performs soft start control in which a duty ratio of at least one of the switching elements is gradually varied from 0% to 100%, and the switching element, in which the soft start control is not performed during the term of the soft start control, is turned off.Type: GrantFiled: August 29, 2016Date of Patent: February 13, 2018Assignee: Mitsubishi Electric CorporationInventors: Nobuhiro Kihara, Noriyuki Wada, Mitsuyasu Kunihiro, Makoto Akashi, Yuta Komatsu, Satoshi Murakami, Yoshihiro Takeshima

Publication number: 20120214740Abstract: There is provided an FGF2 substitute-containing medicinal composition which comprises, as an active ingredient, a chimeric protein comprising the amino acid sequence of an FGF1 protein in which a partial sequence including a sequence of at least positions 62-83 within a sequence of positions 41-83 is substituted with a partial sequence at the corresponding positions in the amino acid sequence of an FGF2 protein; and the remaining region is formed of the amino acid sequence of FGF1. In particular, this medicinal composition is used for wound healing and for the prevention and treatment of radiation-induced damage, and it exhibits a pharmacological action superior to that of an FGF2 medicinal composition, and further, it can be easily formulated into a preparation.Type: ApplicationFiled: April 4, 2012Publication date: August 23, 2012Applicant: National Institute of Advanced Industrial Science and TechnologyInventors: Toru IMAMURA, Kaori MOTOMURA, Akiko KURAMOCHI, Yoshiro HANYU, Masashi SUZUKI, Masahiro ASADA, Akiko HAGIWARA, Fumiaki NAKAYAMA, Makoto AKASHI

Publication number: 20120093807Abstract: An object of the present invention is to clarify unelucidated aspects in the control mechanism of circadian rhythms. The present inventors have newly found that ROR? (retinoic acid binding-receptor alpha; the same shall apply hereinafter) stimulates an induction of Bmal1 expression and also that the induction of Bmal1 expression is promoted under hypoxia. These findings strongly suggest the existence of a control mechanism of circadian rhythms that, when ROR? expression is promoted under hypoxia or the like, an induction of Bmal1 expression is stimulated and, when the induction of Bmal1 expression is stimulated, binding between BMAL1 and CLOCK is stimulated and an induction of Per gene or Cry gene expression is stimulated. The present invention, therefore, has applicability as jet-lag regulating agents and anticancer agents.Type: ApplicationFiled: September 16, 2011Publication date: April 19, 2012Inventors: Takuro Yamamoto, Takayoshi Mamine, Toru Takumi, Makoto Akashi

Publication number: 20110196619Abstract: There is provided a method that achieves the prediction of a biological rhythm with high precision while minimizing the number of times a biological specimen is collected from a subject. There is also provided a method for predicting a biological rhythm of a subject on the basis of time series expression level data obtained by measuring expression levels of two clock genes in biological specimens collected from the subject three times within 24 hours, the clock genes having different phases of circadian cycles of a change in expression levels. In this method for predicting a biological rhythm, a biological rhythm can be predicted with particularly high precision by collecting a biological specimen from a subject three times within 24 hours at eight-hour intervals.Type: ApplicationFiled: October 13, 2009Publication date: August 11, 2011Applicant: SONY CORPORATIONInventors: Haruhiko Soma, Takuro Yamamoto, Makoto Akashi, Koichi Node, Noriyuki Kishii, Kazuhiro Nakagawa, Shiko Yamashita, Tomohiro Hayakawa

Publication number: 20100196901Abstract: To provide a simple and low-invasive method for obtaining information on a biorhythm of an individual organism. Provided is a method for obtaining information on a biorhythm of an individual organism based on variations over time in an expression level of a clock gene in a hair follicle cell of the individual organism. According to this method, a phase shift of the biorhythm of the individual organism can be detected by preparing a plurality of times about the individual organism and conducting a collation. Further, a phase shift of the biorhythm of the individual organism can also be detected by collating an expression level of the clock gene at a predetermined time with the molecular clock table.Type: ApplicationFiled: July 16, 2008Publication date: August 5, 2010Inventors: Takuro Yamamoto, Makoto Akashi, Shiko Yamashita, Tomoteru Abe, Kazuhiro Nakagawa, Haruhiko Soma, Koichi Node, Noriyuki Kishii, Tomohiro Hayakawa

Patent number: 4938071Abstract: A device for detecting the degree of deterioration of bank notes has a driving rotary body and a detection rotary body, which are a pair of oppositely disposed rollers each having alternately disposed enlarged diameter portions and annular grooves. These enlarged portions and the grooves of the two rotary bodies are in staggered, opposed relationship so that when a bank note is conveyed between the two rotary bodies, the note is deformed into a wave shape. The rotation of the driving rotary body influences the rotary movement of the detection rotary body depending on the stiffness of the bank note in the wave shape. When the bank note is new and stiff, the influence is strong, while when the bank note is old and deteriorated with a small stiffness, the influence is small. Such influence is detected from variation in rotary movement of the detection rotary body to which a predetermined rotational characteristic is given by a resistance imparting device.Type: GrantFiled: August 30, 1989Date of Patent: July 3, 1990Assignee: Clory Kogyo Kabushiki KaishaInventors: Tetsuji Kobayashi, Makoto Akashi, Takahiro Yoshikawa, Shigeru Kusaka
