Abstract: A thermal displacement compensation apparatus for compensating a dimensional measurement error due to a thermal displacement of a workpiece, including a machine learning device for learning shape measurement data at the time of inspection of the workpiece, wherein the machine learning device observes image data showing the temperature distribution of the workpiece and shape data after machining as state variables representing the current state of the environment, acquires judgment data indicating the shape measurement data at the time of inspection, and learns the image data showing the temperature distribution of the workpiece and shape data after machining and the shape measurement data at the time of inspection in association with each other using the observed state variables and the acquired judgment data.

Abstract: A storage unit stores first information on at least one of a machine tool and a peripheral device of the machine tool. A control unit includes a generation unit configured to generate a first light emitting pattern which is recognizable to human eyes and which includes a lighting-on state, a lighting-off state, or a lighting-on/off state of a light emitting element, a modulation unit configured to modulate the first information into a light communication signal based on lighting-on/off of the light emitting element unrecognizable to human eyes but recognizable to an electronic device, a superimposition unit configured to superimpose the light communication signal on the first light emitting pattern, thereby generating a second light emitting pattern including the light communication signal, and a light emitting element control unit configured to control the light emitting element on a basis of the second light emitting pattern generated by the superimposition unit.

Abstract: A numerical controller includes: a monitor unit that monitors a water level; a backup unit that performs power supply when a main power source is turned off; and a cutoff circuit that cuts off the power supply, and when the water level monitored by the monitor unit detects a predetermined water level, the power source of the backup unit from an external power source means is cut off. Thus, the power supply is cut off before the flooding occurs in the numerical controller, which makes it possible to reduce the damage caused by electrolytic corrosion.

Abstract: A spinning reel with a handle shaft rotatably supported in a reel body. The handle shaft is connected with a handle. A master gear and a driving spiral gear are provided at separated positions on the handle shaft. The master gear is meshingly engaged with a pinion gear provided integrally with a rotor at the front of the reel body so that rotation of the handle rotates the rotor. A spool shaft fixed with a spool extends in a frontward/rearward direction of the reel body and is oscillatingly movably supported on the reel body. A traverse camshaft is rotatably supported by the reel body. The traverse camshaft is fixedly provided with a driven spiral gear and is formed with a cam groove. A slider member is fixed to the spool shaft and has a pawl engaged with the cam groove so that the slider member is driven to move along the length of the traverse camshaft by rotation of the traverse camshaft.

Abstract: A release preventing device for a fishing reel provided with a one-way clutch that allows a rotating body, such as the spool of a double-bearing type fishing reel and the rotor of a spinning reel, to rotate in one direction but restricts rotation of that rotating body in the other direction. Rotation is restricted in the reverse direction, the direction in which fishing line is released, by a wedge effect, wherein roller members are wedged between an inner race and an outer race.
