A cleansing control apparatus includes: a cleansing fluid projector for projecting a cleansing fluid; a position controller for controlling the position where the fluid from the cleansing fluid projector hits an aimed part; a pick-up part which monitors the color and brightness of the aimed part so as to thereby output an image signal, and a control part which outputs a control signal to the position controller so as to determine the position of the aimed part to be cleaned on the basis of the image signal from the pick-up unit, whereby it is possible to project a medicine, cleanser, toilet water, etc. different from the cleansing water from a second fluid projector, and the aimed part can be properly treated, for example, a wound of the aimed part can be healed or protected.

Cleansing control apparatus

A temperature-adjustable water supply system used for supplying an appropriate temperature water to a water-using object. The system comprises a mixing device coupled to a hot water supply passage and a cold water supply passage for respectively introducing hot water and cold water thereinto and coupled to a water mixture supply passage for supplying the mixture of the hot water and cold water toward said water-using object. The mixing device includes a flow rate adjusting valve assembly for adjusting the mixture ratio of the hot water and the cold water discharged into the water mixture supply passage. A temperature sensor is provided so as to sense the temperature of the water mixture and a temperature setter for setting a target temperature. Also included in the system is a control unit which calculates a temperature deviation on the basis of the temperature of the mixture sensed by the temperature sensor and the target temperature set by the temperature setter. The control unit determines a control amount to the flow rate adjusting valve assembly on the basis of the calculated temperature deviation so as to provide an appropriate mixture ratio of the hot water and the cold water.

Gas shut-off system

An air conditioning system comprises an outdoor unit and a plurality of indoor units, a plurality of delivery conduits for supplying working fluid from a variable capacity energy source located in the outdoor unit to the indoor units, and a plurality of control valves respectively provided in the delivery conduits. A temperature sensor and a reference temperature setting device are provided for each room for transmitting corresponding temperature data to a central control unit. The central control unit detects whether the sensed temperature of each room is increasing or decreasing as a function of time and whether the sensed temperature is above or below a predetermined temperature associated with a value established by the reference setting device. Based upon these data the central control unit provides a control signal for closing the valve to divert a certain amount of the total supply energy to other rooms. Another control signal is generated to increase the total amount of supply energy when the temperature level and its gradient of each room indicate a shortage of the total supply energy and to decrease the total amount when a total energy supply excess is indicated.

Air conditioning system having a plurality of indoor units

This invention is directed to a temperature control apparatus for an air-conditioning apparatus which does not require a manual operation in controlling the temperature of a house room relative to the outdoor temperature. The control apparatus utilizes a micro-computer having a linear function stored thereon. The control of the indoor temperature is carried out by calculating the desired indoor temperature using the linear function of outdoor temperature and controlling the air-conditioning apparatus using the desired indoor temperature.

The present disclosure relates to a power supplier for a magnetron for use in electric appliances, such as a microwave oven. The power supplier of the present disclosure has a solid state frequency converter which changes commercial A.C. power to A.C. power at a high frequency, which A.C. power is increased in voltage in a step-up transformer and then fed to the magnetron. The power supplier further has a control system which stabilizes the power to be applied to the magnetron with respect to a preselected reference level and a power supplier protecting circuit for protecting the power supplier from an unexpected low voltage occurring in the commercial power source.

Power supplier for magnetron

A high frequency heating apparatus in which a combination of a microwave oven for heating food through dielectric heating and a cooking device for heating metallic vessel through electrical induction is incorporated to effect efficient cooking and simultaneous formation of brown scorching on the surface of food. In the heating apparatus, power required for the magnetron of the microwave oven and also for the heating coil of the cooking device is supplied through one inverter unit, by which arrangement, an efficient cooking apparatus of compact size is presented.
