    • A pneumatic tire has a good balance between on-ice and on-snow performances. The tire includes a tread portion having longitudinal and lateral grooves defining block rows. Each block in the block rows includes sipes. A length of each block in the first and second block rows is not less than 1.5 times and not more than 2.5 times a length of each third block row block. A width of each second block row block is larger than a width of each first block row block. The lateral grooves defining the first and second block row blocks are offset in the tire circumferential direction by not less than 0.2 times and not more than 0.8 times the length of each first block row block. The lateral grooves defining the second and third block row blocks communicate with each other while inclining in the same direction.

    • A merged MR head is formed by sequentially stacking a lower shield, a lower shield gap, a magnetoresistive (MR) element, an upper shield gap, a lower magnetic pole/upper shield, a recording gap layer, a coil, a coil insulating layer, and an upper magnetic pole on a side surface of a trailing edge of a floating slider having an air bearing surface. This merged MR head includes a pedestal which is formed on a portion on the lower magnetic pole/upper shield, including the air bearing surface, to have a width larger than that of the upper magnetic pole. The upper magnetic pole is stacked on the pedestal through the recording gap layer. A sidewall of the pedestal in the vicinity of the air bearing surface has a notch which is obtained by forming a plane where a sidewall of the upper magnetic pole is present. A method of manufacturing this merged MR head is also disclosed.

    • A pneumatic tire including rib-like land portions partitioned by a plurality of main grooves extending in a tire circumferential direction and/or block-like land portions partitioned by the plurality of main grooves and a plurality of lug grooves intersecting the main grooves in a tread surface. A plurality of protrusions are provided on a surface of the land portions, and at least two types of the protrusions, having different surface areas, are provided. Moreover, at least a majority of the protrusions adjacent to a small protrusion having a relatively small surface area are large protrusions having a relatively large surface area.

    • In the sand core 10, the tar reducing agent is included in at least the second coating layer 13, which is the outermost layer, of the coating layers 12 and 13. Thus, the tar, which may be generated from the core body 11 and the coating layers 12 and 13 which are positioned thereinside, can be decomposed into low molecular gases (carbon monoxide, carbon dioxide, water, and the like) by heat of the molten metal. As a result, generation of the tar from the sand core 10 to the outside can be prevented. In this case, since the layer which includes the tar reducing agent is the second coating layer 13 which directly contacts the molten metal, the second coating layer 13 can directly receive the heat of the molten metal, and the tar generation prevention effects can be thereby remarkably obtained. Therefore, generation of defects in cast products which may be caused by clogging in the gas drain can be prevented, and structures of the gas drain of the die and the surroundings thereof can be simplified.
    • 在砂芯10中,焦油还原剂至少包含在涂层12和13的最外层的第二涂层13中。因此,可以从芯体11和 位于其内的涂层12和13可以通过熔融金属的热分解成低分子气体(一氧化碳,二氧化碳,水等)。 结果,可以防止从砂芯10向外部产生焦油。 在这种情况下,由于包含焦油还原剂的层是直接接触熔融金属的第二涂层13,所以第二涂层13可以直接接收熔融金属的热量,从而可以实现焦油产生防止效果 显着获得。 因此,可以防止可能由排气堵塞引起的铸造产品的缺陷的产生,并且可以简化模具的排气结构及其周围的结构。
