Title: Hearing aid
Inventor: KUNO MAKOTO
IPC: H04R27/00
Filed: 1980-03-26
Abstract: PURPOSE:To increase the articulation of sound by setting the amplification degree of a vowel independently from that of a consonant. CONSTITUTION:Through filters F1, F2 and F3 having proper bands, an electric signal from microphone M is detected by detectors D1, D2 and D3, whose outputs are applied to comparators C1, C2 and C3. When a vowel enters microphone M, corresponding filters, detectors and comparators operate to open corresponding switches among S1-S3. When a consonant enters microphone M, on the other hand, outputs of comparatos C1-C3 are all at ''0'', so NAND circuit A outputs ''1'' to open analog switch SN, so that a signal which does not pass through any filter will appear at output 0.

Title: Purification device
Inventor: ARAKAWA MASAYUKI
IPC: B01D29/11
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To prevent the flow rate of a fluid to be purified from lowering and improve the cleaning effect of a bobbin filter by causing the passage of the fluid to the outside from the inside of the hollow bobbin filter which purifies the fluid during its passage. SOLUTION: A bath water contained in a bath tub 1 is sent to a purification tank 7 through a suction aperture 2b and a water supply hose 3 using a circulation pump 6 and the drainage and purification process of the bath water from the inside to the outside of a bobbin filter is performed. When the bobbin filter is clogged, it is expanded from the inside by the water pressure of the bath water and consequently, a gap is generated between the threads wound around a cylindrical core to ensure the passage of the bath water, so that the circulatory flow rate hardly decreases. Part of the bath water after purification passes through a first flow path 14, then is heated higher than a specified sterilization temperature in a heating tank 12 and is stored temporarily in a sterilization tank 13.  The bath water flowing through a bypass flow path 15 becomes confluent with the first flow path 14 in the downstream of the sterilization tank 13, and has an optimal temperature for bathing. Further, the bath water makes a reflex into the bath tub 1 from a drainage hose 4 and a discharge aperture 2a. Thus it is possible to prevent the flow rate of the purified fluid from decreasing and maintain the cleaning capability of the bobbin filter for a long time.
