Title: Method of controlling pressurization of hot stove
Inventor: ASAMI HIDEJI
IPC: C21B9/00
Filed: 1984-05-30
Abstract: PURPOSE:To prevent the deterioration of refractories due to thermal shocks and the variation of blast temps. by refuxing the hot air in a hot air main pipe through a hot air pipeline to pressurize a hot stove before the blasting is started. CONSTITUTION:When a combustion stage is switched to a blasting stage in a hot air stove 11, a pressurizing valve 38 is opened immediately before the blasting is started. Consequently, a part of hot air in a hot air main pipe 36 is refluxed through a hot air pipeline 33, and sent into a regenerator (b) which is pressurized. The hot air pipeline 33 is preheated by the pressurization with hot air. Consequently, when the stage is switched to the blasting stage by opening a cold air valve 32 and a hot air valve 34, thermal shocks to refractories in the hot air pipeline 33, a decrease in the temps. of the hot air due to heat absorption by the hot air pipeline 33 and a disorder in temp. control due to the time lag in a temp. sensor can be reduced, and the operation can be carried out smoothly.

Title: Humidifying appliance
Inventor: OOTA AKIRA
IPC: F24F6/08
Filed: 1985-05-23
Abstract: PURPOSE:To prevent a scald from occurring, to make it possible to observe blown-off steam by eyes, to eliminate the blow-off of heavy metals and to prevent the room temperature from lowering, by sending indoor air to a high- temperature portion of steam evolved from an evaporating pan. CONSTITUTION:Water which has been fed from a water tank 1 through a water conduit pipe 3 is stored in an evaporating pan 2 wherein water is heated into a hot water. The water enters into an evaporation process and steam rises up in a humidifying duct 5. On the other hand, a blower 11 sends indoor air which has passed through a filter 12 and air is guided by a guide plate 13 and is supplied to the high temperature portion of steam. The temperature of steam is lowered by the mixing operation of air and steam, and steam is blown off through a blow-off port in the form of a white mist so that a force of appealing to eyes is strong. Further, it does not lower the room temperature so much. Further, heavy metals contained in water are precipitated in the evaporation pan 2 and are not discharged into the room.

Abstract: PURPOSE:To improve the alarming accuracy of a human body detecting sensor by measuring the turning-on time and number of detecting area passing times of persons on the basis of the output of the sensor and changing the discriminating criterion of the sensor in corresponding to time zones. CONSTITUTION:The detecting area of this burglar sensor is divided into numerous small areas and, when a person arrives and passes through one of the small areas, a pyroelectric sensor 1 gives a signal to a off-delay timer 3 and a time measuring section 5 measures the turned on time of the sensor 1. On the other hand, a counter 4 counts the number of pulses from the sensor 1. A clocking controller 8 outputs the signal of either a business time zone or working time excluding the business time and unmanned time zone in night time and on holidays in accordance with the current time. Input correcting sections 6 and 7 correct input values by multiplying input values by factors corresponding to the frequency of occurrence of alarms in the time zones. A fuzzy reasoning section 9 performs fuzzy reasoning following a prescribed fuzzy rule and outputs a signal indicating the degree of doubtfulness of an arriving person.
