Abstract: An engine includes a cylinder block including a cylinder wall, a cylinder liner, and a water jacket. The engine further includes a heater including an induction coil disposed in the water jacket. The heater is configured to heat the cylinder wall by generating an eddy current in the cylinder wall by an alternating current flowing through the induction coil.

Abstract: This instrumentation control system includes: input/output modules provided correspondingly and adjacently to respective field devices; control logic units implemented inside the input/output modules and performing various control calculation processes for the field devices; and a communication network connecting the input/output modules to each other by a communication line.

Abstract: A control panel includes: a cable formed by a plurality of signal lines connected to an input/output unit of the control apparatus; a terminal block to which a plurality of external wirings connecting to a control target device are electrically connected; and an I/F terminal block between the terminal block and the cable. The I/F terminal block includes: a plurality of first terminals provided on the terminal block side and each having a corresponding one of the plurality of external wirings electrically connected thereto; a plurality of second terminals provided on the control apparatus side and each electrically connected to a corresponding one of the plurality of signal lines; and a switching circuit to change a combination of one of the plurality of first terminals and one of the plurality of second terminals connected in a one-to-one relation.

Abstract: A method for filling a gap with a filler material, enabling prevention of inflow of the filler material into an air removing tool through its opening before complete removal of air from the gap, and enabling uniform filling of the gap with the filler material. The gap is between an existing conduit and a lining material provided inside the existing conduit. The method includes: inserting an air removing tool into an air removing hole bored through the lining material, and bringing a leading end face of the air removing tool into contact with the inner circumferential surface of the existing conduit; and injecting the filler material into the gap while expelling air from the gap through a leading end of the air removing tool, the air removing tool including, at its leading end, an air removing portion through which air is discharged.
