Abstract: A method of producing a connecting rod with a bearing, in which both a process for producing a bearing separately from a connecting rod and a process for assembling the bearing to the connecting rod can be eliminated to reduce processes, labor, and costs to produce the connecting rod. A hollow cylindrical molding of a bearing metal material is inserted and fitted, as an inner member, inside an inner surface of a circular large end hole of a large end section of a connecting rod. A tapered surface of a rotary pressing tool is pressed, while rotating, to the hollow cylindrical molding to heat and soften the hollow cylindrical molding, causing the hollow cylindrical molding of the bearing metal material to plastically flow axially and radially outward, whereby a bearing metal layer is directly joined and formed on the inner surface of the large end hole.

Abstract: A sensor unit sensing a physical quantity comprises a first voltage evaluation circuit, a second voltage evaluation circuit, an alarm signal output circuit, and a sensor output circuit. The first voltage evaluation circuit evaluates a power voltage by comparing it with a reference voltage and outputs an accident signal when the power voltage is lower than a first predetermined voltage. The second voltage evaluation circuit working in a lower voltage range in which the first voltage evaluation circuit is insensitive outputs the accident signal when the power voltage is lower than a second predetermined voltage. The alarm signal output circuit outputs an alarm signal in response to the accident signal. The sensor output circuit outputs a sensor signal and inhibits the circuit from outputting the sensor signal in response to the accident signal, so that the alarm signal output circuit provides the alarm signal in response to the accident signal.
