Abstract: A piezoelectric material is described. The piezoelectric material comprises aluminum nitride (AlN) doped with ytterbium (Yb), an atomic percentage of Yb in the AlN being greater than or equal to approximately 10.0% and less than or equal to approximately 27.0%. Piezoelectric layers comprising the piezoelectric material may be used in bulk acoustic wave (BAW) acoustic resonators, and surface acoustic wave (SAW) acoustic resonators. The BAW acoustic resonators and SAW acoustic resonators can be used in a variety of applications.

Abstract: It is provided a processor system comprising at least one processor core including a processor, a memory and an accelerator. The memory includes an instruction area, a synchronization flag area and a data area. The accelerator starts, even if the processor is executing another processing, acceleration processing and executes read instruction in a case where the read instruction is a flag checking instruction and a flag indicating the completion of predetermined processing has been written; and stores the data subjected to the acceleration processing after completion of the acceleration processing, and further writes a flag indicating the completion of the acceleration processing. The processor starts, even if the accelerator is executing another processing, read instruction corresponding to a flag in a case where the read instruction is the flag checking instruction and it is confirmed that the flag indicating the completion of the acceleration processing has been written.

Abstract: A surface chemical treatment apparatus provided with: a first conduit having an opening at one end and communicating with a liquid supply means at the other end; a second conduit having at one end an opening that surrounds the opening of the first conduit and communicating with a liquid suction means at the other end; and a moving mechanism for moving the openings of the first and second conduits relative to the solid phase surface, so as to make a surface chemical treatment possible in a fine pattern by allowing the patterning solution to be dispensed through the opening of the first conduit while allowing the solution to be suctioned up together with the surrounding liquid phase or gas phase medium through the opening of the second conduit that surrounds the opening of the first conduit and, thus, preventing seepage of the solution in all directions.

Abstract: The present invention provides a method for selectively separating a straight-chain conjugated diene with high purity from a mixture containing the straight-chain conjugated diene and at least one type of straight-chain olefin. The method involves separating the straight-chain conjugated diene from the mixture containing the straight-chain conjugated diene and the straight-chain olefin using a zeolite membrane composite. The composite contains a porous support and a zeolite layer formed on the surface and in the fine pores of the support, and the zeolite contains an alkali metal cation.

Abstract: A self-healing wire includes, an electric wire arranged on a substrate, and a hybrid structure in which the electric wire is covered with at least one fluid selected from the group consisting of a fluid having conductive particles dispersed therein and a fluid having metal ions dissolved therein, formed on a healing portion for a crack to be generated in the electric wire. And a stretchable device includes the self-healing wire formed on a stretchable base material and an electric element mounted only on a base material higher in rigidity than the stretchable base material. Even when a crack is generated in the electric wire due to stretching of the substrate having flexibility, the crack is bridged by the conductive particles or a solid metal deposited from the metal ions in the fluid. Thus the self-healing wire and the stretchable device having both high conductivity and high stretchability are provided.
