  • Publication number: 20220379869
    Abstract: A revolution position of an engine is set to a revolution position suitable for a start. A control apparatus for an electric vehicle includes an engine, a motor which generates electricity, a battery, a first controller which drives the engine, a second controller which drives the motor, and a sensor. The second controller confirms a relative position relationship between a revolution position of the engine and a rotation position of the motor by acquiring information of the revolution position of the engine from the first controller during the electricity generation driving by the motor and monitors the revolution position of the engine based on the relative position relationship and a signal from the sensor, and the second controller checks the stop position of the engine through the monitoring of the revolution position of the engine when the motor finishes the electricity generation driving.

  • Publication number: 20220381190
    Abstract: Closing timing of an intake port is changed without using a variable valve timing mechanism. An electric vehicle includes an engine for electricity generation in which closing timing of an intake port maximizes intake air charging efficiency in a specific revolution speed region, a sensor which outputs a signal related to a revolution speed of the engine, a controller which drives the engine at a revolution speed based on the signal of the sensor, a requested electricity generation amount being satisfied at the revolution speed, and a motor which applies a positive or negative torque to the engine. When the engine is driven in a revolution speed region other than the specific revolution speed region, the controller uses the motor to apply a positive or a negative torque to the engine in an intake stroke to change the closing timing of the intake port to increase intake air charging efficiency.

  • Patent number: 11480905
    Abstract: An image forming apparatus includes: an image carrier; an exposing device; a developing device with a developing roller; a development current detector that detects development current between the image carrier and the developing roller; and a hardware processor. Under an image forming condition, the hardware processor causes the exposing device to draw, on the image carrier, a development current-detection pattern that includes a solid image and a halftone image that follows the solid image in an image-conveying direction of the image carrier, causes the developing device to develop the development current-detection pattern, obtains information on a chronological change of the detected development current from the development current detector, and determines whether or not a ghost image due to the solid image occurs based on a temporary drop of the detected development current during development of the halftone image.

  • Publication number: 20220213217
    Abstract: The present inventors produced a variety of bispecific antibodies that specifically bind to both F. IX/F. IXa and F. X, and functionally substitute for F. VIIIa, i.e., have a cofactor function to promote F. X activation via F. IXa. Among these antibodies, the antibody A44/B26 reduced coagulation time by 50 seconds or more as compared to that observed when the antibody was not added. The present inventors produced a commonly shared L chain antibody from this antibody using L chains of A44, and showed that A44L can be used as commonly shared L chains, although the activity of the resulting antibody is reduced compared to the original antibody (A44HL-B26HL). Further, with appropriate CDR shuffling, the present inventors successfully produced highly active multispecific antibodies that functionally substitute for coagulation factor VIII.
