摘要： PURPOSE:To reduce waste materials, a cost, etc., by constituting a seal material in such a way that an elastic material is formed in a pole shape, and a longitudi nal notch is formed and also opposing notch surfaces are reversed to outer circumference sides respectively so as to be used in their condition formed in annular shapes. CONSTITUTION:A seal material 24 is formed in a pole shape with an elastically deformable material, and also a notch 38 which cuts through along longitudinal direction except the both ends in the longitudinal direction. Two opposing notch surfaces 40 which are formed by the notch 38 are respectively reversed to the outer circumference sides so as to be used in their condition formed in annular shapes. Namely, both ends of the notch 38 are laid on hands, and two opposing notch surfaces 40 formed by the notch 38 are expanded. Both notch surfaces 40 are peeled off so as to be push-opened to this side, and both notch surfaces 40 are reversed in surfaces orientated outward. In the seal material 24, a shoulder part is cut in slant sides 39 viewing from adhesive surface 36 side or a seal surface 37 side, and the slant sides 39 are joined with each other so as to be reversed in an annular shape approximately in a complete circular form.

摘要： PURPOSE:To reduce a level of noise caused by ventilating resistance, by disposing heating elements such as resistances or the like in an air passage from an auxiliary internal air intake port to a sub air intake area in a casing having a plurality of internal air intake ports and an auxiliary internal air intake port. CONSTITUTION:A blower A for an air conditioning device comprises a centrifugal main casing 2A for accommodating a centrifugal multi-blade fan 1, upper and lower casings 2B, 2C coupled with the main casing 2A in such a manner that they are confronted with main and sub air intake areas a, b partitioned by a partition plate 1e of the fan 1 and a fan motor 10. A group of resistances 11 serving as a part of a means for controlling electric power supplied to the motor 10 are disposed in confrontation with an air passage at a suitable location on the inner surface of the lower casing 2C from an auxiliary internal air suction port 14 provided on the side wall surface of the lower casing 2C to the sub air intake port b of the fan 1. With this arrangement, the group of the resistances 11 are cooled effectively and a level of noise caused by ventilating resistance can be reduced.

摘要： PURPOSE:To prevent a reverse flow under such a condition as outside air reversely flows in from an inside air intake port and makes occupants uncomfortable in a semi inside air mode and to set an inside/outside air mode matching with the air conditioning condition at that time when the reverse flow does not badly affect the occupants. CONSTITUTION:In a semi inside air mode in which both of an inside air intake port 5 and an outside air intake port 6 are opened, a reverse flow is prevented by setting an outside air introducing mode if a blower voltage applied to a blowing means 8 is lower than a reference value. This control is carried out only in such a condition as makes occupants uncomfortable by the reverse flow, while this control is not carried out and the semi inside air mode is maintained if reverse flow is not caused greatly.

摘要： PURPOSE:To increase the dynamic pressure ventilation quantity by arranging in parallel an air conditioning duct equipped with air conditioning parts inside and equipped with an inside/outside air introducing port, switching means, and a car-interior blow-out port and a ventilating duct for connecting the above- described inside/outside air selecting means and the car-interior blow-out port. CONSTITUTION:The air conditioner parts 1 consist of a blower 2, evaporator 3, and heater core 4. An air conditioning duct 5 for accommodating these parts 1 is constituted of an inside/outside air selecting box 51, three-way branched box 52, defroster blow-out duct 53, center blow-out duct 54, and at-feet blow-out duct 55. A ventilation duct 6 for dynamic-pressure ventilation set in parallel to the air conditioning duct 5 is constituted of a subinside air introducing port 61, subinside air opening/closing damper 62, ventilation duct inlet 63, and outlet 64. Therefore, when ventilation is performed by introducing the outside air into the car interior only by the traveling wind pressure of a car, the resistance of an outside air passage can be reduced to the min. Further, the inside air introducing area can be spread by an inside air introducing port 57 and the subinside air introducing port 61.

摘要： PURPOSE:To eliminate the unpleasant feeling by the variation of the air capacity, by suppressing the generation of the variation of air capacity generated by prohibiting the outside air introduction in the scope the numerical aperture is small side as low as possible, in order to prevent an air cutting sound, as well as to prevent the air cutting sound owing to a ram pressure and an outside air introduction. CONSTITUTION:The outside air introduction prohibiting means 20 of a control device 12 does not prohibit the outside air introduction in the scope the numerical aperture is small side when the car speed is less than 10km/h. When the car speed is in the scope 10 to 60km/h, the outside air introduction in the scope the numerical aperture is 0 to 10% is prohibited. When the car speed is 120km/h or higher, the outside air introduction in the scope the numerical aperture is 0 to 30% is prohibited. Consequently, the prohibition of the outside air introduction which generates no air cutting sound is released, the variation rate of the numerical aperture by prohibiting the outside air introduction is reduced, and the variation of the air capacity is reduced, when the car speed is low.

摘要： PURPOSE:To eliminate a temporal, abrupt change of an amount of blast while assure a prescribed amount of blast in a stationary state by providing control means slowly changing an amount of operation of internal/external air introduction switch means or blast adjusting means in conformity with an instruction. CONSTITUTION:A fan 12 is operated in a stationary state in conformity with a signal from a speed control circuit 17. Switched now a switching damper 11 from introduction of fresh air to that of internal air, an instruction switch 19 is switched on interlocking with the switching damper to close a contact of a timer circuit 20, whereby electric charges changed on a capacitor 21 to that time is discharged in a moment via a resistor 22. For this, a transistor is switched off while a transistor 24 switched on, whereby a transistor 15 is switched off and a motor current passes only through the resistor 1, and thus the fan 12 is operated at low rpm. In succession, when the timer 20 reaches its time limit and opens its contact, the capacitor 21 is gradually changed, whereby the transistor 15 gradually increases the motor current to permit the operation to be returned to the original state.
摘要翻译：目的：通过提供控制装置缓慢改变内/外部空气引入开关装置或爆炸调节装置的操作量，以消除爆炸量的瞬时，突然变化，同时确保在静止状态下规定量的爆炸一个指令构成：风扇12根据来自速度控制电路17的信号在静止状态下操作。现在切换开关风门11从新鲜空气引入到内部空气，指令开关19被切换为与切换阻尼器以闭合定时器电路20的触点，由此电容器21上的电荷变化的电荷经由电阻器22在一定时间内被放电。为此，晶体管24接通时关闭晶体管，由此，晶体管15关断，电动机电流仅通过电阻器1，因此风扇12以低转速运转。连续地，当定时器20达到其时间限制并打开其接触时，电容器21逐渐变化，由此晶体管15逐渐增大电动机电流，以允许操作返回到初始状态。

摘要： PURPOSE: To prevent contamination of steam and damage of a compressor, by detecting temperature of compressed steam concentrically in a discharge chamber at high and low temperature regions, and stopping operation of the compressor at abnormal high and low temperatures.
CONSTITUTION: A temperature sensor 7 is constituted of a high temperature sensor and a low temperature sensor which are arranged adjacent to each other. Coefficient of thermal expansion of a metal piece A (bimetal) of the high temperature sensor is larger than that of B. Accordingly, when temperature increases, a rod 3 comes into contact with an upper switch spring. Coefficient of thermal expansion of a metal piece C of the low temperature sensor is smaller than that of D. Accordingly, when temperature decreases, a rod 4 comes into contact with a lower switch spring 2. Both the sensors are connected to each other to form a circuit leading from an electrode 8 to an electrode 9. There is defined an operational gap in the circuit near high and low set temperatures, and the gap is opened and closed according to temperature of compressed steam in a discharge chamber 15 to engage and disengage a clutch (not shown), thus controlling operation of a compressor. At abnormal high and low temperatures, the operation of the compressor is stopped to prevent contamination of the steam and damage of the compressor.
