摘要:
The present invention provides a method for washing a separation membrane module after filtering raw water containing particles having a hardness higher than that of a separation membrane. Thus, after completion of filtration, water at the primary side in a separation membrane module is drained to outside the system, backwash waste water in the separation membrane module is then drained while carrying out backwash, and any of the steps of: (a) filling the primary side in the separation membrane module with water and carrying out air scrubbing; and (b) carrying out air scrubbing while feeding water to the primary side in the separation membrane module is then carried out, followed by draining water at the primary side in the separation membrane module to outside the system.

A system for successively extracting unprocessed substrates from a cassette, successively conveying the extracted substrates to a plurality of processing units, causing the processing units to process the substrates, and successively returning processed substrates to a cassette is disclosed. In the system, corresponding to a recipe that contains process conditions for each of at least one lot, a process start prediction time at which processes of each lot start and a process completion prediction time at which processes for each lot are completed are calculated for at least two processes. Corresponding to the process start prediction time and the process completion prediction time, at least one of optimum processing units that optimize processes for each lot is selected for each lot.

摘要:
A circuit breaker of different interruption speeds, and a spring operation mechanism is standardized for designing and manufacturing the circuit breaker. The circuit breaker has a power transmission mechanism for driving a movable contact 63 and a fixed contact 64 and an interruption spring 26 that imparts a driving force to separate the contacts through the power transmission mechanism. A latch mechanism restricts movement of the power transmission mechanism, and a pull-out operation section releases the restriction of the power transmission mechanism by the latch mechanism. The pull-out operation section is arranged to oppose a first arm of a lever to rotate the first arm. The lever is arranged so that a tip of a second arm is able to engage with and rest on the latch mechanism, and release the restriction of the power transmission mechanism by the latch mechanism.
摘要:
Disclosed is a hydraulic operating apparatus for switch with which it is possible to constantly obtain a stable interrupting performance at the time of high-speed successive operations. Closing and interrupting pressure accumulators comprise closing and interrupting pressure accumulation pistons, and closing and interrupting pressure accumulation springs for biasing the closing and interrupting pressure accumulation pistons in pressure accumulation directions, respectively. The closing and interrupting pressure accumulation springs exert, on the closing and interrupting pressure accumulation pistons, forces corresponding to received pressures acting on the closing and interrupting pressure accumulation pistons from closing and interrupting pressure accumulation chambers in a steady state. The closing pressure accumulator and the interrupting pressure accumulator are independently constituted for closing and for interrupting, respectively.

A sound data processing apparatus includes a central processing unit for controlling predetermined processing in the apparatus, a rewritable RAM, a decoder performing the decoding processing for sound data, and an interface unit for being fitted with an external memory. The sound data processing apparatus reads a driver from the external memory mounted in the interface unit and stores the read driver into the RAM, and reads the sound data from the external memory with the driver and processes the read sound data. As a result, the wastefully using of the memory capacity of the memory mounted in the sound data processing apparatus is reduced.
