摘要： PROBLEM TO BE SOLVED: To provide an automatic gate controller that reduces a control error as much as possible and permits accurate control without increasing a load on and drive current for gate facilities for a dam or the like.
SOLUTION: The gate automatic controller is provided with a controlled variable computing part 101 for computing the target opening degree Gm of a gate and a gate control part 102 for controlling the opening/closing operation of the gate. Furthermore, the automatic gate controller, for operating the gate in the open direction or the closing direction to attain a target opening degree, controls such that it factors an amount Q of excessive operation of the gate to be operated even after the gate has received a halt instruction, issues the halt instruction at the time point when the actual opening degree of the gate becomes Gm-Q during operation in the opening direction, and issues the halt instruction at the time point when the actual opening degree of the gate becomes Gm+Q during operation in the closing direction. With the automatic gate controller as above, an amount Qr of actual excessive operation when the gate is operated during certain gate operation is found, and actual excessive amount Qr of operation is used for an expected excessive amount Q of operation from certain gate operation through the following gate operation, thereby performing the gate control.

摘要： PROBLEM TO BE SOLVED: To solve the problem that an air-cleaning filter becomes a resistor against the circulation of air when the filter is mounted to the dehumidification passage of a conventional dehumidifier and hence its original dehumidification effect deteriorates. SOLUTION: An air-cleaning passage is provided separately from a dehumidification passage in this dehumidifier to form structure where the dehumidification passage is not affected even if the amount of wind of the air-cleaning passage is decreased by a filter. Further, wind passing through the air-cleaning passage and dehumidification wind are mixed when air is not cleaned by removing the filter to form air for drying clothes, thus reducing drying time.

摘要： PROBLEM TO BE SOLVED: To solve the problem that necessary data are not determined at the end of an updating process since various data are updated in a database and the updating process is performed in the order of the actual update of data at the time of the generation of a replica even when using methods and necessity of the data are different. SOLUTION: The priority of a replica generating process for some kind of data is stored, updated data of the database are preferentially extracted according to the priority, and replicas are updated with the extracted data.

摘要： PURPOSE:To facilitate air-conditioning which is combined with a freezing cycle and performs automatic control as the efficiency of temperature exchange is always kept at 100% so that not only ventilation is solely effected but also disturbance is prevented from being exerted on indoor hot heat environment in the situation wherein the degree of secrecy and heat insulation of a housing is increased. CONSTITUTION:During cooling operation in a summer season, air at the exterior 1 of a room is fed through an air-conditioning ventilating element 8, a cooler 11 located therebehind, an indoor discharge blower 13, and an indoor discharge 22. Air from the interior 2 of a room is heat-exchanged through the air-conditioning ventilating element 8, a reheater 12 located therebehind, an outdoor discharge blower 16, and an outdoor discharge port 5 and discharged to the exterior 1 of a room. During heating operation in a winter season, the cooler 11 and the reheater 12 are switched by means of a four-way valve to perform air-conditioning ventilation operation. Heat exchange during dehumidifying operation is effected in a similar manner described in that during cooling in a summer season and is carried out in a state that dehumidifying switching dampers 26a and 26b are changed over and the outdoor discharge port 5 and an outdoor suction port 4 are closed.

摘要： PURPOSE:To shorten drying time of clothing, by a method wherein out of two air current blowoff ports where opening areas vary in size the air current blowoff port whose opening area is wide is formed into the rear front of the air current of a heating source. CONSTITUTION:Air current blowoff ports 14, 15 are formed, an opening area of the air current blowoff port 14 is made wide and arranged at the front of the rear of the air current of a heating source 19. The air current dehumidified and reheated by passing through a cooler 17 and reheater 18 at the time of drying of clothing is heated by the heating source 19, a temperature is raised and blown off through the air current blowoff port 14. Therefore, the heating source 19 can be exposed to the air current by controlling an increase of ventilation resistance and without reducing an air quantity, heating value of the heating source is increased and drying hours of the clothing can be shortened. The air current blowoff port 15 is used at the time of spot drying where operation is performed by connecting the same with a duct hose.

摘要： PURPOSE:To improve reliability, to eliminate the need for a heat resistant material, and improve work efficiency of inspection and replacement, by a method wherein heat dissipated from a heater after operation is stopped is discharged into a chamber through a gap between a hole in the bottom of a fan casing and a closing plate for the hole. CONSTITUTION:During inspection and replacement of a heating preventing device 19 and a temperature fuse 20, by removing a decorative cover 2 and a screw 12 of a closing plate 21, and the closing plate 21 and pulling off the receptacle of a lead wire 25 and the receptacle of a lead wire 27 on the power source from a temperature fuse 20, they are completely separated from an air conditioner body 1 to effect inspection. In replacement, the heating preventing device 19 and the screw 12 for securing the temperature fuse 20 are removed to perform inspection. Since an electric heater 9 for heating is placed to the rear part of a vaporizer 8, there is no risk of the heater making contact with a human body and therefore, even if the heater is not cooled, inspection and replacement can be effected. Further, since a high temperature heat, generated during operation of the heating preventing device 19 and the temperature fuse 20, an air conditioner, requiring no heat resistant material nor heat insulating material, can be provided.
