  • Patent number: 10099965
    Abstract: Carbon opals, a form of colloidal crystal, are composed of ordered two-dimensional or three-dimensional arrays of Monodispersed Starburst Carbon Spheres (MSCS). Methods for producing such carbon opals include oxidizing as-synthesized MSCS, for example by heating in air, to increase surface charge. Such oxidation is believed to decrease settling rates of a colloidal suspension, enabling formation of an ordered colloidal crystal. Inverse opals, composed of any of a wide variety of materials, and based on a carbon opal template, have a reciprocal structure to a carbon opal. Inverse opals are formed by methods including: forming a carbon opal as described, impregnating a desired material into pores in the carbon opal to produce a hybrid structure, and removing the carbon portion from the hybrid structure.

The seed shaft (28) includes a cylinder part (28A), a bottom part (28B), and a low heat conductive member (28C). The bottom part (28B) is located at the lower end of the cylinder part (28A) and has the lower end surface (28S). The low heat conductive member (28C) is arranged on the upper surface of the bottom part (28B) and has a thermal conductivity lower than that of the bottom part (28B). This production apparatus can make the temperature within the crystal growth surface of the SiC seed crystal less liable to vary.

  • Patent number: 10101742
    Abstract: Mixed autonomous and manual control of a vehicle is provided. The vehicle can include an operational mode in which the vehicle operates autonomously but is influenced by a mix of autonomous control inputs and manual control inputs. A first weight can be assigned to manual control inputs, and a second weight can be assigned to autonomous control inputs. The assigned first and second weights can be applied to a vehicle system. Responsive to receiving a manual control input, the autonomous operation of the vehicle can be caused to be influenced by the received manual control input in an amount corresponding to the first weight without deactivating the autonomous operation of the vehicle.

  • Patent number: 10100763
    Abstract: In a control apparatus for use an internal combustion engine in which warming-up time air fuel ratio control is executed, the air fuel ratio of the exhaust gas flowing into the three-way catalyst is changed to an air fuel ratio higher by the predetermined amount, by using as a trigger the timing at which a measured value of an air fuel ratio sensor indicates a rich air fuel ratio. In addition, when the timing at which the measured value of the air fuel ratio sensor indicates the rich air fuel ratio is earlier than a reference timing, the starting-time-rich-air-fuel-ratio in the next and following warming-up time air fuel ratio control is corrected to an air fuel ratio which is higher than that in the current warming-up time air fuel ratio control.

  • Patent number: 10100925
    Abstract: After engagement of a clutch is suppressed from being started and a rotational speed of an input shaft of an automatic transmission is suppressed from being increased due to an increase in rotation resistance of the input shaft of the automatic transmission, which occurs by half-engagement of a clutch, the clutch is disengaged, and the clutch is completely engaged. In this way, the clutch is completely engaged after the rotational speed of the input shaft is suppressed from being increased. Thus, a heat generation amount of the clutch can be reduced, and furthermore, durability of the clutch can be improved by a reduction in the heat generation amount.
