A detector is operable to detect a displacement of a load by an ascending force based on a period of time from a time a heating output of an inverter drops from a predetermined level to a first level, to a time the heating output returns back to a second level larger than first level. Thereby, the detector distinguishes an intentional removal of the load from the displacement of the load by the ascending force. An induction heater including the detector reduces the displacement of the load by the ascending force and stops the heating of the load when the load is removed intentionally.

In an induction heating apparatus, in order to decrease the buoyancy exerted on an object to be heated which is made of a material having high electrical conductivity and low magnetic permeability, such as aluminum, an electrical conductor is provided between a heating coil and the object to be heated, thereby increasing the equivalent series resistance of the heating coil. Hence, the current of the heating coil, which is required for obtaining a desired heating output, is decreased, whereby the buoyancy of the object to be heated can be decreased. In addition, the electrical conductor is divided into two halves, and they are arranged in a circular arc form with a clearance provided therebetween and made close contact with the bottom face of a plate, whereby the temperature rise of the electrical conductor can be restricted. Furthermore, the heat of the electrical conductor is transferred and dissipated to the object to be heated, whereby the heating coil and the like are not damaged even if the electrical conductor is heated. An electrical conductor temperature sensor for detecting the temperature of the electrical conductor is provided; when the detection temperature becomes a predetermined temperature, the heating output of a drive circuit is decreased, whereby the heat generation of the electrical conductor is decreased and the heating coil and the like are not damaged by heat.

An induction heater having a safety function of lowering or stopping the heating power when an object to be heated moves, the safety function hardly interfering with the cooking activities of a user is provided. The induction heater of the present invention comprises an induction heating coil, an inverter circuit, an output detection section for detecting the magnitude of the inverter circuit, a control section, a setting input section for setting a target output, a first movement detection section, and a storage section for storing a control value before the first movement detection section detects a movement of an object to be heated. The control section has a reach control mode where the output of the inverter circuit is gradually increased from a low output to a target output, a stable control mode where control is exercised so that the output of the inverter circuit agrees with the target output, and a first output mode where a control value derived from the control value stored in the storage section is output, and when the first movement detection section detects a movement of the object, the control section shifts to the first output mode.
摘要:
After deposition of a conductor film made of titanium tungsten over a main surface of a semiconductor substrate formed with grooves, an initial conductor film made of aluminium is further deposited. Subsequently, the conductor film is made to reflow and run into the grooves. Thereafter, while heating, further conductor films are respectively deposited, thereby causing these conductor films to run into the grooves. The provision of the initial conductor film suppresses or prevents aluminium in the further conductor films and silicon in the semiconductor substrate from reacting with each other during reflowing of the conductor films.

A method for an automatic transmission includes measuring torque of a component of the transmission using a torque sensor in communication with the component. The torque of the component is estimated from information other than the measured torque. The measured torque is rejected from being used in a control operation of the transmission if the difference between the measured torque and the estimated torque is greater than a selected threshold.
摘要:
A non-synchronous automatic transmission up-shift control utilizes input torque measurements. The input torque is measured during an up-shift having preparatory, torque, and inertia phases. Target input torque profiles for the torque and inertia phases are determined based on the input torque during the preparatory phase. During the torque phase, an engine torque is controlled to cause the input torque to achieve the target profile for the torque phase. During the inertia phase, the on-coming clutch is controlled to cause the input torque to achieve the target profile for the inertia phase.
