Abstract: A dissimilar metal joint structure includes a first and second joining materials and a three-dimensional structural body. The structural body is joined to the top of the first joining material. Spaces in the structural body are filled with the second joining material, so that the second joining material is geometrically integrated with the structural body. The structural body is joined to the first joining material at an interface. The second joining material is charged into the spaces in the structural body and is integrated with the structural body. The first and second joining materials are joined together via the structural body. Because the second joining material is charged into the spaces in the structural body, the second joining material and the structural body are strongly joined and integrated together by the anchor effect. Inducing metallurgical reaction at the interface between the first and second joining materials can increase bonding strength.

Abstract: A recording medium transport and transfer belt includes at least a base material layer and a surface layer, in which a ratio (?s500/?v500) between surface resistivity ?s500 and volume resistivity ?v500 at an applied voltage of 500 V is 1.0 or more, and a difference (?s100??s500) between surface resistivity ?s100 at an applied voltage of 100 V and surface resistivity ?s500 at an applied voltage of 500 V is 0.3 or less.

Abstract: A transfer device includes an intermediate transfer belt that has an outer peripheral surface to which a toner image is to be transferred, a primary transfer device that has a primary transfer member performing primary transfer of a toner image formed on a surface of an image holder to the outer peripheral surface of the intermediate transfer belt, and a secondary transfer device that has a secondary transfer belt arranged in contact with the outer peripheral surface of the intermediate transfer belt and performing secondary transfer of the toner image transferred to the outer peripheral surface of the intermediate transfer belt to a surface of a recording medium, in which the intermediate transfer belt has an indentation modulus A of 5,000 MPa or more, and the secondary transfer belt has an indentation modulus B of 300 MPa or less and a tensile modulus C of 250 MPa or more.

Abstract: In an endless belt, the absolute value of an electrostatic capacitance C and the absolute value of an alternating-current resistance Z when an alternating voltage of 1 Vp-p is applied in a frequency range of from 10000 Hz to 0.1 mHz from a high frequency side satisfy Formula (1) below, and an alternating-current resistance Z0.63 when an alternating voltage of 1 Vp-p with a frequency of 0.63 Hz is applied satisfies Formula (2) below. Moreover, an alternating-current resistance Z630 when an alternating voltage of 1 Vp-p with a frequency of 630 Hz is applied satisfies Formula (3) below: log10 C?3.18×log10 Z?30.27;??Formula (1): 6.3?log10 Z0.63?6.9; and??Formula (2): 9.1?log10 Z630?9.9.

Abstract: A package opening knife has a body part, a blade part, a gripping part that extends in an elongated shape in a prescribed first direction, and a guide part provided with a guide surface that slides in a surface direction of the package in a state of contacting the package to guide movement of the blade part. When a surface direction of the guide is defined as a second direction, the first direction and the second direction become substantially parallel to each other.

Abstract: A memory system of an embodiment includes a nonvolatile memory, a primary cache memory, a secondary cache memory, and a processor. The processor performs address conversion by using logical-to-physical address conversion information relating to data to be addressed in the nonvolatile memory. Based on whether first processing is performed on the nonvolatile memory or second processing is performed on the nonvolatile memory, the processor controls to store whether the logical-to-physical address conversion information relating to the first processing to be in the primary cache memory as cache data or logical-to-physical address conversion information relating to the second processing to be in the secondary cache memory as cache data.

Abstract: A razor comprises: a head portion, a connecting portion and a gripping portion. The width dimensions of the gripping portion are set to be equal to or greater than the width dimension of the head portion and to increase gradually toward the side leading away from the head portion. The connecting portion linearly connects together both ends of the head portion and both ends of the gripping portion. The height of the connecting portion is set to be smaller than the height dimension of the head portion and the height dimension of the gripping portion. The gripping portion comprises a top surface part, a pair of the side wall parts and rib parts that are slanted in the longitudinal direction, the vertical direction and the width direction. The top surface part, the pair of side wall parts and the rib parts include placement surfaces on which a user's fingers can be placed.
