    Abstract: Disclosed are an aluminum alloy casting having a high strength and a high toughness, and a production process for the same. The aluminum alloy casting comprises silicon (Si) in an amount of 2.5 to 4.4% by weight, copper (Cu) in an amount of 1.5 to 2.5% by weight, magnesium (Mg) in an amount of 0.2 to 0.5% by weight and the balance of aluminum (Al), and a matrix thereof includes a dendrite which has a size of 30 micrometers or less. Since the Si addition amount is suppressed as less as possible and since the size of the dendrite is micro-fined in the aluminum alloy casting, the toughness is improved remarkably. Further, since the Cu and Mg are added in the predetermined addition amounts, the strength is enhanced in the aluminum alloy casting. In addition, a solution treatment which is employed in the production process can further enhance the strength of the aluminum alloy casting.

    Abstract translation: 公开了具有高强度和高韧性的铝合金铸件及其制造方法。 铝合金铸件包含2.5〜4.4重量％的硅（Si），1.5〜2.5重量％的铜（Cu），0.2〜0.5重量％的镁（Mg），0.2〜0.5重量％ 铝（Al）的平衡和其基体包括具有30微米或更小的尺寸的枝晶。 由于Si添加量尽可能少地被抑制，并且由于在铝合金铸件中枝晶的尺寸微细化，所以韧性显着提高。 此外，由于以规定的添加量添加Cu和Mg，所以在铝合金铸件中强度提高。 此外，在制造方法中使用的固溶处理能够进一步提高铝合金铸件的强度。

    Abstract: A linear actuator is provided which is able to simplify its structure by adding a stopper function, too, to a detent mechanism and to prevent generation of radial load. The linear actuator comprises a ball screw mechanism, to which a rotational driving force is transmitted, for converting a rotational motion into a linear motion. The ball screw mechanism comprises radially projecting guide projections provided in a linear motion component, and a guide groove arranged in a securing portion facing the linear motion component and is engaged with the guide projections to guide the guide projections in an axial direction. The guide projection has a projection projecting by the predetermined length, while engaging into the guide groove, at a stroke end of the linear motion component and a locking portion provided in a rotary motion component is locked to the projection of the guide projection.

    Abstract: In an exemplary method a piezoelectric wafer is prepared on which multiple piezoelectric frames are formed. Each frame has a piezoelectric vibrating piece including excitation electrodes, and a frame portion surrounds the vibrating piece. A lid wafer is prepared on which multiple respective lids are formed, each sized substantially similarly to the respective frames. A base wafer is prepared on which multiple of bases are formed, each sized substantially similarly to the respective frames. Each base has through-holes. Stripes of a first bonding film are formed on both major surfaces of the piezoelectric wafer around the periphery of each frame. Stripes of a second bonding film are formed on the inner major surface of the lid wafer, corresponding to respective stripes of the first bonding film. Stripes of a third bonding film are formed on the inner major surface of the base wafer, corresponding to respective stripes of the first bonding film. A bonding material is placed between the stripes of first bonding film and respective stripes of second bonding film, and between stripes of first bonding film and respective stripes of third bonding film, by which the three wafers are bonded together after being aligned with each other in a sandwich manner.

    Abstract: A piezoelectric device employs solder on a roughened surface to improve bonding of electrical contacts with the device package. The device package includes a base, a crystal frame and a lid. The base includes connecting electrodes on a side of the base adjacent the crystal frame.

    Abstract: An exemplary piezoelectric device includes a piezoelectric vibrating piece, on which excitation electrodes are formed, and a piezoelectric frame having a frame portion surrounding the piezoelectric vibrating piece. A plate (e.g., lid or base) is bonded to one surface of the frame portion. Fitting members are provided on both the frame and the plate. When the piezoelectric frame and plate are brought together for assembly, the fitting members fit together (e.g., interdigitate) to provide quick and error-free alignment. Then, the fitting members are bonded together by a bonding material.

    Abstract: A transaction coordinating device 100 is composed, in which a transportation adjusting portion 140 is provided for adjusting an insertion of cargo transportation of a spot transaction with respect to a schedule of single and/or plural cargo transportation of predetermined fixed transactions, in the event an insertion of a spot transaction based on a temporary contract with respect to fixed transactions based on the contracts of predetermined period of time is adjusted. Accordingly, inserting cargo transportation of a spot transaction easily into a schedule of single and/or plural cargo transportation of fixed transactions becomes possible even in the event that a spot transaction arises suddenly, and further inserting a commodity transaction under a flexible contract into commodity transactions under rigid contract simply also becomes possible.
