Title: Heating/cooking appliance
Inventor: DOI SADAYUKI
IPC: A47J27/00
Filed: 1989-12-08
Abstract: PURPOSE:To restrain the release of steam to the outside, and also to obtain a heating/ cooking appliance with good usability, when the steam generated from the article to be heated is passed through a steam passage and is introduced to a heat exchanger for condensing it into water, by arranging the steam passage and the heat exchanger in the inside of the apparatus. CONSTITUTION:When rice and water are housed in a vessel 7 and a heater 8 is electrified for heating them, the steam generated passes through an inner cover 28 and is filled in the space under an outer cover 21, and then passing through steam pipes 24, 17, it is introduced into a heat exchanger 11. When it passes through the heat- radiating part 15, the heat energy retained by the steam is deprived through a heat- radiation fin group 14 and then is stored in a heat-storing material 16. As a result, steam is condensed and converted into water, and turning into dew, it flows out into a second dew receiver 19. In this case, since the steam passage formed by the steam pipes 17, 24 and the heat exchanger 11 is successively lowered from a steam intake port 26 to the second dew receiver 9, the water condensed into dew in the inside of the steam passage can successively flow into the dew receiver 9. Thus, since generated steam can be securely converted into water in the inside of the appliance, a scald due to the bust of high-temperature steam can be prevented.

Filed: 1994-12-22
Abstract: PURPOSE: To provide an operation priority calculating device which can properly determine the priority levels of respective operations in a production process wherein there are plural operations and an operator performs the respective operation in order. CONSTITUTION: The operation priority calculating device M2 calculates the deviation in the current quantity of stock from a reference quantity through a deviation calculating means M8 from (current number of stock)-(reference quantity of stock) as to respective products M6-M6 obtained by respective operations M4-M4, and the deviation is an index showing how much the stock quantity of each product has a margin. Further, an acceptance quantity expected value calculating means M10 calculates an acceptance quantity expected value and the value is an index showing how high the probability that each product is accepted from a postprocess is at present in the form of a quantity.  Therefore, a product which is larger in acceptance quantity expected value needs to be produced earlier and a product which is larger in deviation may be manufactured later, so an operation priority calculating means M12 calculates operation priority from (operation priority) = (acceptance quantity expected value) -(deviation).

When two circuits are symmetrically installed on the two load transistors T4 and T5 of the differential comparator, a fraction common to two variable voltages U1 and U2 of the two pseudo motors stabilizes the average non-load level of the outputs S1 and S2. The difference of U1 and U2 compensates offset between the output S1 and S2.
