摘要： PURPOSE:To provide a recycle apparatus for an antifreezing soln. informing the life of a treatment material or stopping regeneration treatment work when the life of the treatment material is exhausted, and execellent in repairing properties, handling properties, economical efficiency and maintenance and having reliability. CONSTITUTION:The used antifreezing soln. 25 received in a treatment soln. tank 9 is treated with a treatment device 1 and the regenerated soln. is stored in a regenerated soln. tank 10. During this regeneration treatment work, the life of filters 3a, 3b is judged from the pressure of the front flow of the filters detected by a pressure detector 12a and the life of a reverse osmosis membrane 5 is judged from the flow rate of the transmitted soln. flowing through a pipe 8f and the life of an ion exchange resin 6 is judged from the electric conductivity of the rear flow of the ion exchange resin measured by an electric conductivity meter 14. When the lives of those elements are judged, this state is informed to a user and the operation of the apparatus is stopped according to circumstances. The flow rate of the transmitted soln. can be detected by weighing the residual amt. of the treatment soln. tank 9 or regenerated soln. tank 10 by a liquid amt. detector 11.

摘要： PURPOSE:To perform stable illumination even when light quantity of a light sensor is suddenly changed by providing a hysteresis circuit and a delay circuit. CONSTITUTION:Circuit power is supplied from a battery 1, and circuit protection and action stabilization are performed by a power supply circuit 3. a current at an optical sensor 2 is converted into a voltage to be inputted to a lighting/ lighting off determination circuit 4 provided with hysteresis, and when the voltage signal is less than a specified voltage, a voltage of 0V is outputted to a delay circuit 5 to put a relay 6 on immediately for lighting an illuminating lamp 17. When the inputted voltage signal into the circuit is the specified voltage or more, a voltage of 5V is outputted to the circuit 5, and only in the case where this output continues for a specified delay time or more, the relay 6 gets off to light off the illuminating lamp 7. In the meanwhile, the set specified delay time is changed as a capacitor capacity inside the circuit 5 changes. Stable illumination is thus provided even when light quantity of a light sensor is suddenly changed.

摘要： PURPOSE:To provide an air conditioner that increases no air-flow resistance and has a built-in inexpensive air cleaner. CONSTITUTION:A sub air flow passage different from a main air flow passage is formed in an intake box, and an air cleaner 7 is installed in this sub air flow passage. In addition, in order to induce cabin inside air forcibly into this air cleaner 7, an intake door 28 is divided into an inside air door 5 and an outside air door 6 and thereby the main air flow passage is made so as to be closable. Apart from the main air flow passage in the intake box, the sub air flow passage for the air cleaner 7 is installed in particular, so that any air-flow resistance will in no case increase, and since a blower is used in combination, there is such an effect that an inexpensive air cleaner integral type air conditioner is thus providable.

摘要： PURPOSE:To obtain the electric air cleaner which imparts refreshing sense to clean air and is excellent in performance and quiet by equipping a negative ion generating needle, a negative discharge electrode and a positive dust collecting electrode having a damping function as a constitutional element. CONSTITUTION:A discharge electrode 5 and a dust collecting electrode 6 are arranged in the passage 1 of an air flow in a cleaner main body. A negative ion generating needle 9 is installed in the downstream side of the dust collecting electrode 6 in the passage 1 of the air flow. The electric air cleaner is set so that negative voltage is impressed to the discharge electrode 5 and positive voltage is impressed to the dust collecting electrode 6. Further the dust collecting electrode 6 is constituted of an electrode member having a damping function and of a sandwich structure in which synthetic resin 11 is pinched between two sheets of conductive plates 6a, 6b. As a result, the electric air cleaner which imparts refreshing sense to the clean air and is excellent in performance and quiet is obtained.

摘要： PURPOSE: To prevent an abnormal motion from occurring as well as to improve safety in operation by setting up a detective device for performing both on-off operations on a power supply circuit for a battery and a braking device at the same time, in a handle part. CONSTITUTION: When a detective device 8 is grasped, it is turned on, and thereby a judging circuit 10a receives an on signal, outputting a Hi signal. If this judging circuit 10a outputs this Hi signal, a current flows into a coil 6a of a braking device 6, whereby an armature 6b is attracted to the side of a field core 6c, and a clearance is produced between a brake disk 6d and this armature 6b, releasing the braking device 6. Therefore the current flows into a power supply circuit 10b which is turned on and thereby voltage of a battery 11 is imposed on a control circuit 10c which feeds the current conformed to a turning angle of a speed regulating volume 9 to a motor 2 from the battery 11.

摘要： PURPOSE:To eliminate an obstacle to the field of view of a car on the opposite lane and simultaneously prolong the service life of a light by performing automatic illumination suitable for the running condition of a vehicle. CONSTITUTION:A lighting or light-out determining circuit 3 with a hysteresis, taking a photo sensor 2 as input, and a car speed sensor take-in circuit 5, taking a car speed sensor 4 as input are connected to a delay time determining circuit 6, and a relay 7 is put between a battery power supply 1 and a light 8. Thus, the delay time is changed depending on the car speed to eliminate frequent ON-OFF of the light, so that an obstacle to the field of view of a car on the opposite lane can be eliminated and simultaneously lengthen the life of the light so as to accomplish stable automatic illumination.

摘要： PROBLEM TO BE SOLVED: To provide a regenerating device for antifreeze capable of performing cleaning action for a reverse osmotic membrane by automatically judging the lowering of the function of the reverse osmotic membrane during the antifreeze regenerating operation. SOLUTION: A 1st rout for performing the regeneration of the antifreeze, a 2nd rout for cleaning the reverse osmotic membrane with water and a 3rd rout for cleaning with a chemical are provided and when it is discriminated by a signal from an electrical conductivity meter provided in an ion exchange resin 6 that the ion exchange resin reaches the life during the regeneration working, it is judged that the function of the osmotic membrane 5 is lowered and the cleaning rout is automatically switched to the 2nd and the 3rd rout. Since the reverse osmotic membrane 5 is automatically cleaned when the function of the reverse osmotic membrane 5 is lowered in the regeneration working of the antifreeze, the lowering of the function of the reverse osmotic membrane 5 is accurately judged, the switching work to the cleaning rout by manual is made needless and the efficiency of the regeneration of the antifreeze is improved.
