  • Publication number: 20180208644
    Abstract: The present invention mainly addresses the problem of providing an antibody against semaphorin 3A protein, said antibody enabling effective prevention and/or treatment of a disease, in which Sema 3A protein participates, such as a neurodegenerative disease, autoimmune disease, inflammatory disease, cancer, infectious disease, etc. or disseminated intravascular coagulation syndrome. An anti-Sema 3A antibody comprising CDRs having specific amino acid sequences (SEQ ID NOS: 1-6, 60-62, 64-66, 68-70, 72-74, 76-78, 80-82, 84-86 and 88-90) enables effective prevention and/or treatment of a disease, in which Sema 3A protein participates, such as a neurodegenerative disease, autoimmune disease, inflammatory disease, cancer, infectious disease, etc. or disseminated intravascular coagulation syndrome and, therefore, remarkably ameliorates symptoms associated with such a disease.

  • Patent number: 9970403
    Abstract: When a start condition is satisfied after the internal combustion engine has been stopped according to an automatic stop control, a control apparatus reversely rotates the engine to compress an air in an expansion stroke cylinder at that time point, and thereafter generates a first time combustion. The apparatus determines whether the start condition becomes satisfied based on a first start request owing to a driving operation by a driver of a vehicle on which the engine is mounted. When the start condition becomes satisfied based on the first start request, the control apparatus makes a maximum value of an engine generating torque by the first time combustion and/or a maximum torque of the engine generating torque by a second time combustion larger as compared to when the start condition becomes satisfied based on a second start request other than the first start request.

  • Patent number: 9586576
    Abstract: A control device is applied to a hybrid vehicle (1A) in which an internal combustion engine (2) and an MG (3) are connected through a second clutch (21), the MG (3) and a transmission (10) are connected through a first clutch (20) whose state is switchable by a depression operation of a clutch pedal (CP), and an output shaft (12) of the transmission (10) is connected to a driving wheel (5) so as to transmit power. The control device starts the internal combustion engine (2) when an accelerator opening is equal to or greater than a start determination value. When the vehicle (1A) is stopped and the internal combustion engine (2) is stopped, and when the amount of return of the clutch pedal (CP) is small, the control device makes the start determination value greater than when the amount of return of the clutch pedal (CP) is great.
