An immersion type membrane filter apparatusis intended for obtaining filtrate by filtrating a fluid to be processed stored within a storage bathand primarily includes a filtration membrane moduleand an air bubbles supply devicedisposed therebelow. The filtration membrane modulehas numerous tubular membraneshaving on the inner surfaces thereof the function of filtrating a fluid to be processed packed within a cylindrical housing vesselhaving a discharge portfor filtrate. The tubular membranesare held in an opened state at both the ends of the housing vessel. The filtration membrane moduleis soaked in a fluid to be processed in such a way that the tubular membranesare opened in the vertical direction. When air bubbles are supplied to the filtration membrane modulefrom an air bubbles supply device, the fluid to be processed flows through the tubular membranesfrom the down side upwards to naturally circulate within the storage bath. Part of the fluid to be processed is filtrated by passing through the tubular membranesfrom the inside to the outside. As a result, the filtrate thus obtained flows out via the discharge portto a filtrate discharge pathway

Immersion type membrane filter

An encoding apparatus includes an interval register (250), a calculator (208, etc.), means for providing a potential shift-amount (Shift.sub.-- LSZ) of the interval register for the image data in a specific condition (LPS), a shift-amount decision circuit (258), a shift-amount register (259), and a shifter (251). The interval register stores plural bits of interval data to be used for encoding the image data. The calculator updates the interval data in the interval register. The shift-amount decision circuit generates an actual shift-amount of the interval register, in accordance with the potential shift-amount and the output of the calculator. The shift-amount register stores the actual shift-amount, supplied from the shift-amount decision circuit. The shifter shifts the interval data in the interval register a plurality of bits at one time, in accordance with the actual shift-amount stored in the shift-amount register.

Apparatus for encoding image data

A conversion parameter for a (N)th image data is read from the information table (201) while converting a (N-1)th image data, which is inputted one clock prior to the (N)th image data. The (N)th image data is converted in accordance with the previously read conversion parameter when the conversion of the (N-1)th image data is completed.
