  • Patent number: 4606719
    Abstract: The disclosure is directed to a safety arrangement adapted to detect the incomplete combustion of a burner to stop the combustion in a combustion apparatus for burning a mixture of fuel and air. Through employment of an oxygen concentration cell type sensor (25), by setting the burner to be at a low air/fuel ratio (rich air/fuel mixture), ignition performance has been improved, while simultaneously, through utilization of the fact that the sensor electromotive force is large during a low air/fuel ratio, it is made possible to detect the ignition of the burner quickly and positively.In addition, it is so arranged that voltage is applied to the sensor (25) from outside, so that, by utilizing temperature characteristics of the internal resistance of the sensor (25), misfire of the burner is positively detected.

  • Patent number: 4492336
    Abstract: A high performance automatic temperature control system enables fries and Japanese tempura to be prepared in optimum condition.The temperature of the outer bottom surface of a container being heated is measured by a temperature sensor a given time later. A temperature rise gradient of the temperature sensor established at a given time in the initial stage of heating is used as a temperature correction value peculiar to the container, while a temperature rise gradient of the temperature sensor established after a certain temperature has been reached is used as a temperature correction value for the amount of food being cooked. The former and latter temperature correction values are converted into preset temperature values and serve as operating temperatures for the temperature sensor.When the temperature sensor reaches the operating temperature, the heating rate is controlled to hold the operating temperature.

  • Patent number: 4465228
    Abstract: A highly automationed cooking apparatus especially suitable for stew cooking or the like liable to boiling over. Temperature of outer bottom face of a pan is measured by a sensor and temperature gradients are sampling-measured at a sampling time pitch. Boiling point of food material is detected by finding a decrease of the temperature gradient, and thereafter the heating is lowered to avoid boiling over to a suitable value which is given by processing the temperature gradients.

  • Patent number: 4393858
    Abstract: A combustion control system having incorporated therein an electronic circuit for driving and controlling a proportional control valve provided on a fuel supply line to control the amount of combustion and thereby maintain the temperature of fluid to be heated by combustion at a constant level even when the amount of the fluid varies per unit time. The output voltage of a bridge circuit including a sensor for detecting the temperature of the fluid as a component is fed to operation amplifiers for differentiating, integrating and proportional amplification to control the control valve with the resulting output. The system is best suited for use in instantaneous water heaters.

  • Patent number: 4170339
    Abstract: An electromagnetic valve comprises a magnetic circuit formed by a stationary core and a movable core, or armature pivoted at one end of the stationary core and rotatable continuously between first and second positions with a free end positioned in opposed relation to the other end of the stationary core with an air gap therebetween. The armature is spring biased so as to remain in the first position and carries a valve head for engagement with a valve seat. The opposing ends of the stationary and movable cores are so shaped as to form in the air gap a first working section in which the main magnetic flux generates a vector component transverse to the length of the armature and a second working section in which the main magnetic flux generates a vector component parallel to the length of the armature. The resulting vector makes the angular displacement of the armature linearly proportional to the supply current.
