  • Patent number: 9328026
    Abstract: A raw ceramic portion is formed on each of first and second lateral surfaces of a raw ceramic body. The raw ceramic portions contain ceramic particles and more of at least one constituent selected from Ba, Mg, Mn, and a rare-earth element between the ceramic particles than the ceramic section of the raw ceramic body in terms of total amount. The raw ceramic body is fired with the raw ceramic portions thereon. In this way, a ceramic electronic component is obtained that has a main body left after the raw ceramic body is fired with the raw ceramic portions thereon.

  • Patent number: 7211027
    Abstract: An apparatus for controlling an automotive vehicle including an engine and an automatic transmission. The apparatus is operable upon generation of an engine-output control command requiring an output of the engine during a shift-up action of the transmission initiated in the absence of the engine-output control command, and includes a shifting-progress calculating portion operable to calculate a degree of progress of the shift-up action of the transmission after a moment of generation of the engine-output control command, on the basis of a change of a rotating speed of a rotary element which changes with the progress of the shift-up action, and a gradual-engine-torque-increase control portion operable to control the engine on the basis of the degree of progress of the shift-up action calculated by the shifting-progress calculating portion, so as to gradually increase an output torque of the engine with the progress of the shift-up action.

  • Patent number: 6643118
    Abstract: A solid-phase method for making a barium titanate powder involves the steps of compounding powdered barium carbonate and powdered titanium oxide and calcining the mixture. The powdered barium carbonate used is needle particles having an aspect ratio of the length of the long axis to the length of the short axis of at least about 2. The powdered barium carbonate preferably has a specific surface area of about 5 m2/g or more. The resulting barium titanate powder is finer and homogeneous.

  • Publication number: 20030113446
    Abstract: A method for making a dielectric ceramic material powder containing a basic component powder including particles of a basic component for making a dielectric ceramic, a first additive component and a second additive component is provided. The first additive component has an effect of preventing the second additive component from forming a solid solution with the basic component powder. The method includes the steps of diffusing the first additive component into a surface region of each particle of the basic component powder, and adding the second additive component to the resulting basic component powder. After the dielectric ceramic material is sintered, each of the particles of the sintered compact can reliably have a core-shell structure that includes a core containing no second additive component and a shell containing diffused second additive component.

  • Publication number: 20030012727
    Abstract: A barium carbonate powder having a specific surface area of at least about 20 m2/g is mixed with a titanium oxide powder to form a powder mixture. The titanium oxide powder has such a specific surface area that the specific surface area ratio of the titanium oxide powder to the barium carbonate powder is at least about 1. The powder mixture is calcined and thus results in a fine barium titanate powder having a high content of tetragonal crystals and a small range of compositional variation.

  • Patent number: 6390949
    Abstract: An apparatus for controlling a vehicle automatic transmission, wherein a moment at which the supply of a pressurized fluid to a hydraulic cylinder for engagement of a frictional coupling device to effect an upshift of the transmission during running of the vehicle in a power-off state is initiated is determined by comparing an estimated synchronizing time required for the transmission input speed to reach a synchronizing speed of a higher-gear position to which the transmission is shifted, with a stored predetermined stroking time required for the piston of the hydraulic cylinder to reach its engaging stroke end.
