摘要： PROBLEM TO BE SOLVED: To speedily deal with the characteristic change or control specification change of a motor-driven air blower. SOLUTION: The vacuum cleaner is provided with a motor-driven air blower 2 for sucking litter, a current detecting means 21 for detecting a current flowing through the motor-driven air blower 2, a control means 23 for controlling the input of the motor-driven air blower 2 based on the output of the current detecting means 21 and a non-volatile storage means 22 for storing the control value of the control means 23 based on the output of the current detecting means 21. Since the control means 23 reads plural phase controlled variables and controls the motor-driven air blower 2 with this read phase controlled variable, the control change can be performed only by changing the stored contents in the storage means 22.

摘要： PROBLEM TO BE SOLVED: To provide a garbage treatment apparatus by which finishing can be detected at high precision even in the case the environments during treatment and the conditions of the garbage whose treatment finishing is just being determined are changed. SOLUTION: This garbage treatment apparatus comprises a finishing determining means 39 which detects the maximum value based on the detection temperature of a finishing sensor 32 and stores the value and finished heating dry after a determined time passes from the time when the temperature is lowered from the maximum value by a determined temperature. The finishing determining means 39 contains two determination values, i.e., determination temperature Δt1/determination time T1 and determination temperature Δt2/determination time T2 and in the case the temperature is not lowered to the determination temperature Δt1 due to environment condition alteration, the other determination temperature Δt2 is employed, so that the dry finishing time can be detected even if the environment condition changes.

摘要： PROBLEM TO BE SOLVED: To provide a garbage disposer in which heating treatment is appropriately performed at the shortest necessary time without receiving effect by ambient temperature in the automatically finishing garbage disposer. SOLUTION: A controlling means 35 starts a time check of set time T from a point of time when only a first set temperature Δt1 is lowered for the highest value of temperature inputted from a second temperature sensor 34 during generation of steam. A drying heater 23 is continuously heated and operated. It is judged at any time whether a fall of at least a second set temperature Δ2 is not caused for the temperature inputted from the second temperature sensor 34 at this time. When a fall of at least Δ2 is not caused at a point of time that set time T elapses, heating is finished. In the case except this, heating treatment is performed at the shortest necessary time regardless of ambient temperature by repeating operation at set time T.

摘要： PROBLEM TO BE SOLVED: To preferentially energize a heater of a gas sensor part on applying power source and to perform stable action even in a DC power source part of small capacity by installing a DC power source in which power source capacity is set so that a driving current when a built-in heater of a gas sensor part is cool can be supplied. SOLUTION: A gas sensor heater 27b is closed by a NC relay contact of a heater control part 29 in an initial state thereof. Since a microcomputer 36 does not perform action until a reset releasee voltage of about 4V is reached, impedance of a control circuit system is equal to that of the gas sensor heater 27b. When a power source is applied in this state, output of a DC power source part 37 rises toward about 5V, but since its voltage is about 4V or less, all the current from the DC power source part 37 flows to the gas sensor heater 27b and is consumed exclusively for heating the heater.

摘要： PURPOSE: To accurately control the travelling of a robot by detecting only the effect of weave texture of a carpet in the straight advance travel even in the case of direction change or meandering. CONSTITUTION: A carpet weave texture detection means 24 detects a deviation angle between a travel direction and an object direction of a robot due to the effect of the weave texture of a carpet and gives the deviation angle to a control means 21. The control means 21 is provided with a convergence detection means 52 to detect it that the deviation angle is converged into a value corresponding to the straight advance travel in succession to a direction conversion of the robot or avoidance of an obstacle of the robot, and the control means 21 uses only the deviation angle after the convergence to exclude the deviation angle information other than the weave texture of the carpet resulting from the direction conversion or avoidance of the obstacle thereby controlling the straight advance travel. Moreover, the convergence is detected in the process of a 1st process by the discrimination of the deviation angle and a 2nd process by the discrimination of a time change rate of the deviation angle calculated by a differentiation means 53. Furthermore, a spin-turn means 54 or a meandering means 56 sets a reference output for the carpet weave texture detection means based on the converged deviation angle in the case of the straight advance travel in succession to a spin-turn or meandering.
