Inventor: KUWABARA KATSUMI
IPC: C02F1/00
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To provide a small-sized purifier for a bathtub effectively filtering hot bathwater though an existing afterburning heater can be utilized to sanitarily purity hot bathwater and capable of being repeatedly used as a result and capable of being especially adapted to a unit bath as it is.

Title: Amplifier
Inventor: AKITA SHINICHI
IPC: H03F1/30
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To realize stabilization by extremely simple constitution by connecting a stabilized capacity between a node to stabilize voltage and a power source terminal. SOLUTION: When power is supplied and a power source voltage is boosted with time, the voltage of the node 4 is also boosted linked with coupling operation by a capacity 10. Even when operations of a differential amplifier 3 and a constant current circuit 7 are not stable because a power source voltage is not sufficient at this time, the potential of the node 4 is controlled linked with the power source voltage to make an output transistor 5 active to be conductive. As a result of this, the voltage of an output terminal 6 remains at a ground level and a noise is not generated. At the point in time when the power source voltage is established after this, the coupling operation of the capacity 10 is not generated so that the potential of the node 4 comes to be controlled mainly by the output voltage of the amplifier 3.  On the other hand, when the power source is disconnected, the potential of the node 4 is linked with the dropping of the power source voltage so that the potential does not become unstable to prevent the generation of noise.
