A joined body includes: a thin plate including through holes; a first member including a proximal portion having a portion contacting the thin plate, and a protruding portion that protrudes in relation to a contact surface of the proximal portion and is inserted through the through hole; and a second member arranged oppositely to the proximal portion via the thin plate and made of a material that is same as that of the first member. The thin plate is made of a material having a specific gravity smaller than that of the material forming the first and the second members. The second member and an end portion of the protruding portion are connected to each other, by a part of the second member and a part of the end portion being melt-solidified, the end portion being at a side opposite to a side connected to the proximal portion.

Joined body, automobile seat frame, and joining method

A joined body includes: a thin plate including through holes; first members each including: a base portion and a protruding portion inserted into one of the through holes; and a second member placed oppositely to the base portion via the thin plate and made of a material that is of a same kind as a material of the first members. The thin plate is made of a material having a specific gravity smaller than the materials of the first and the second members. The second member and an end portion of the protruding portion are connected together by melt-solidification. A post-joining hardness difference in a range of 30% along a direction orthogonal to a joint interface between the second member and the protruding portion, the range being centered on the joint interface, is equal to or less than 90% of a pre-joining hardness difference.

An optical module includes a photoelectric converter configured to receive an optical signal having an intensity that changes at one of a first frequency or a second frequency that is higher than the first frequency, and convert the optical signal into a current signal corresponding to the intensity of the optical signal; a signal processor configured to acquire, when the optical signal has the intensity that changes at the first frequency, wavelength information set on a transmitting side based on a ratio between a plurality of signal intensities included in the current signal relating to the optical signal having the intensity that changes at the first frequency; and a decoder configured to generate, when the optical signal has the intensity that changes at the second frequency, communication data from the current signal relating to the optical signal having the intensity that changes at the second frequency.

Optical module and optical communication system

To provide an optical module whose power consumption in an ambient temperature range is reduced, and an optical transmission equipment. The optical module includes: a housing; a box type optical subassembly including a bottom portion serving as a heat dissipation face; and a heat conductive member disposed between the bottom portion of the optical subassembly and a bottom portion of the housing. The optical subassembly includes one or a plurality of optical semiconductor devices, and a temperature controller on which the one or plurality of optical semiconductor devices are mounted and which is placed on an inner bottom portion of the optical subassembly. The heat conductive member is disposed only at a portion of the bottom portion of the optical subassembly.

A transaction coordinating deviceis composed, in which a transportation adjusting portionis 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.
