Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To simply remove a plate material nailed to a wooden frame by circularly cutting a plate material nailed to the wooden frame in the periphery of the nail to be separated from the wooden frame. SOLUTION: When the surface of a veneer plate 20 is damaged over application limit by the repeated use of a wooden panel, a cutting tool 40 is used to cut out the veneer plate 20 in a circle in the peripheries of nails 30, 30. The cutting tool 40 is installed on a motor-driven drill to be used, and includes a cylindrical cutting blade main body and a bar shaft-like cutting blade holding part provided concentrically inside the cylindrical part of the cutting blade main body.

Abstract: PURPOSE:To prevent the equipment overheating as well as the poor cooking quality by determining from the presence or lack of the drive signal output and the applied voltage level to the input terminal whether the relay operation is normal or faulty every time the cooking start command signal is generated, and stopping the operation and activating the warning device when there is a failure. CONSTITUTION:When the start switch is turned on, the output is arbitrarily designated as 0. The input terminal I determines whether the input thereto is 0, and, if 0, the relay coil 8a is determined to have been failed and discontinued. The drive signal is then inhibited from being outputted to prohibit the cooking operation, and the warning device 18 is activated to sound off a buzzer. If it is determined that the input is 1, the output from the output terminal S is designated as 1, and the input terminal I determines whether the input is 1 or not. If the input remains to be 1, the relay coil 8b is determined to have been shorted, and the cooking operation is prohibited and the warning device 18 is activated. If the input is 0, it is determined that the operation is normal, and the cooking operation is executed in accordance with the prescribed operation program.
