Title: Cutting device
Inventor: MAEJIMA MAKOTO
IPC: B24B27/06
Filed: 2019-09-09
Abstract: To recognize a height (an initial height) of a cutting blade when a tip of the cutting blade comes into contact with a holding surface while suppressing damage to the holding surface.SOLUTION: On an image G taken with a camera 66, a height of a cutting blade 63 is determined at the time when the cutting blade 63 comes into contact with a shadow 63s of the cutting blade 63 projected on a holding surface 300. By subtracting a correction value from the height, an initial height of the cutting blade 63 can be determined. Thus, the cutting blade 63 is not brought into contact with the holding surface 300 when determining the initial height of the cutting blade 63, and thereby can suppress the cutting blade 63 from damaging the holding surface 300.SELECTED DRAWING: Figure 5

Abstract: To provide a hot water filling control device capable of eliminating restriction on an installing direction and a water-draining line and securely discharging internal water during water draining.SOLUTION: A solenoid valve 103 is provided in a hot water supply passage connecting a water heater with a bathtub. A filter 101 removing foreign matters is provided upstream of the solenoid valve and a check valve 104a is provided downstream of the solenoid valve.

An air intake valve 107 closed by pressure of hot water and opened by spring force is connected to a space between the solenoid valve and the filter. Due to this configuration, since the atmosphere release valve is opened only by draining water in a passage for supplying clean water to the water heater, hot water between the check valve and the solenoid valve is drained. When the hot water in the hot water supply passage from the water heater is drained, the air intake valve is opened to take in air between the solenoid valve and the filter, and thus the hot water between the solenoid valve and the filter can be also drained.SELECTED DRAWING: Figure 2
