IPC: H02M3/07
Filed: 1993-11-09
Abstract: PURPOSE: To operate two charge pump circuits as a push-pull type basic bias pump by delaying an input signal used for pumping an electric charge stored in a substrate from a pumping capacitor and turning on a pumping transistor. CONSTITUTION: Electric charge pumping circuits 22, 24 are provided in a circuit path from the input of a generator 14 to a substrate 20 and supply an electric charge to the substrate 20 responding to the level of an oscillating signal. Since these circuits have similar constitution, for example, the circuit 22 transfers the charge stored from a pumping capacitor 61 to the substrate 20 while a pumping transistor TR 50 does not make all threshold voltages of TR 50 a voltage loss. The conductive path of TR 50 is connected between the capacitor 61 and the substrate 20 as a serial circuit, the control gate electrode of TR 50 is connected in a bootstrap manner and TR 50 is turned on by delaying the input signal for pumping the charge to the substrate 20 from the capacitor 61.

CONSTITUTION:The water is introduced from a flow-in port 11, comes into a vessel 21 situated above, and flows into a main filter module 3 situated below via a communication hole 13 in the base 1. The water stagnates in the vessel 21 until a certain water head pressure is attained which is required for the water to pass through a hollow filter 33 in a main filter module 3. With rising of the water level in the vessel 21, the air in the vessel 21 is lifted and released to outside from an air bleeder plug 40 situated above. When the water level rises above an upper plate 23a, water intrudes from a small hole 42a into a guide 42 of the air bleeder plug 40. Now a liquid absorptive swelling material 43 absorbs the water and swells, and a valve element 44 is put in pressure contact with the lower part of air bleeder hole 41 to generate the valve closed condition. When the water pressure further rises, the valve element 44 is put in stronger pressure contact with the lower part of the air bleeder hole 41, and perfect water-proofness is achieved.
