Title: Draining device
Inventor: UNO SHIGEKI
IPC: F24H9/16
Filed: 1987-05-28
Abstract: PURPOSE:To reliably detect the occurrence of water leak if a drain plug is insufficiently inserted and to prevent the occurrence of a phenomenon in which ignition is impracticable even when water flows, by a method wherein an inner and an outer O-ring, situated on the outer peripheral surface of the drain plug of a water boiler, are situated so that the inner O-ring is first sealed and the outer O-ring is then sealed. CONSTITUTION:An inner O-ring 14 mounted to a low pressure drain part 13a is brought into slide pressure contact with the inner surface of a low pressure chamber drain passage 17, communicating to a low pressure chamber 6, and an outer O-ring 15 mounted to a high pressure drain part 13b with the inner surface of a high pressure drain passage 16, (also communicating to the low pressure drain passage 17) communicating to a high pressure chamber 5. When a drain plug 13 is insufficiently inserted (fastened), the outer O-ring 15 is not sealed, water leaks past the high pressure drain passage 6, and it is reliably detected by a user that insertion of the plug 13 is insufficient. In this case, the inner O-ring 14 completely cuts off the high and low pressure drain passages 16 and 17, and phenomenon in which ignition is impracticable even when water flows is prevented from occurring.

Title: Muffling device for cooling system
Inventor: ADACHI KOSAKU
IPC: F04B39/00
Filed: 1991-06-05
Abstract: PURPOSE:To display a noise control effect in a constantly best condition with the active control of noise made in a stable condition even under a situation where ambient temperature is lowered. CONSTITUTION:An artificial sound, having a reverse phase to and a frequency and amplitude same as that of noise from a compressor 3 in a ventilating hole 2a, is generated by processing a signal from a pickup 4 to actuate a speaker 5 in a computing element 9, and the noise is eliminated by the artificial sound. This muffling effect is monitored with a microphone 6 to be converted into a frequency signal Sp, and when a monitored sound is not within an allowable range, the operation coefficient of the computing element 9 is corrected based on the frequency signal Sp to make adaptive control with an adaptive control circuit 10. When the temperature near to the speaker 5 is lowered to deteriorate its low frequency characteristic, the low-frequency component of the frequency signal Sp is not attenuated with a frequency discrimination circuit 11, performing no adaptive control in a frequency band where the low frequency characteristic of the speaker 5 is deteriorated. Consequently the diffusion of an adaptive control system is eliminated, allowing the active control of noise in a constantly stable condition.
