Abstract: A semiconductor device includes a substrate, a first adhesive layer, a first semiconductor chip, and a second adhesive layer. The first adhesive layer is provided above a first surface of the substrate and includes a plurality of types of resins having different molecular weights and a filler. The first semiconductor chip is provided above the first adhesive layer. The second adhesive layer is provided in at least a part of a first region between the substrate and the first adhesive layer, and the second adhesive layer includes at least one type of resins among the plurality of types of resins having a molecular weight smaller than a molecular weight of other types of resins among the plurality of types of resins, and a filler having a lower concentration than that of the first adhesive layer.

Abstract: A tightening tool such as a torque wrench is provided in which electric power can be fed to an electronic circuit with eliminating the need for a battery and achieving daily maintenance-free. In the tightening tool, when a tightening torque has reached a set torque value and a torque limiter is actuated, an electronic circuit unit that has obtained a detection signal outputted from a torque limiter actuation detection unit outputs a tightening completion signal. The tightening tool has a power generation unit for feeding electric power to the electronic circuit unit at least during the actuation of the torque limiter. The power generation unit performs photovoltaic power generation, electromagnetic induction power generation, power generation by conversion from mechanical energy into electrical energy, or temperature difference power generation.

Abstract: The torque tool device includes a torque tool and an information processing terminal. The torque tool is capable of measuring the torque value at which a bolt or the like was tightened and then transmitting the measured torque value via wireless communication unit and the information processing terminal has information processing unit receiving the measured torque value and determining whether the torque value is acceptable.

Abstract: An object is to provide a torque tool device which can expedite tightening operations using a torque tool without requiring any other manipulation than the tightening. The device is also capable of performing tightening operations consecutively by determining instantly whether the tightening has been adequately performed. The torque tool device includes a torque tool 1 and an information processing terminal 20. The tool 1 is capable of measuring the torque value at which a bolt or the like was tightened and then transmitting the measured torque value via wireless communication means. The terminal 20 has information processing means for receiving the measured torque value and determining whether the torque value is acceptable. This arrangement eliminates the need of including a pass/fail test device in the torque tool 1, thereby allowing it to be reduced in weight.

Abstract: An object is to provide a torque tool device which can positively identify which torque tool was used to tighten a bolt. Another object is to provide a torque tool device which can be provided with traceability from the torque tool to standards of torque. A torque wrench 1 transmits, after having tightened a bolt, a set of the manufacturer's serial number of the torque wrench 1 and tightening data such as a measured torque value to a processing terminal 20. The processing terminal 20 transmits the manufacturer's serial number and the tightening data to an externally connected device 30, so that the tightening data and data on the tightened bolt or the like are recorded by the manufacturer's serial number in the externally connected device. This makes it possible to identify the torque wrench 1 from the tightened bolt and maintain traceability.
