摘要:
An intake control system includes an intake control valve disposed in a common intake pipe connected to engine cylinders or a plurality of intake control valves disposed in intake pipes connected respectively to the engine cylinders. The intake control valves are openable and closable under the control of an electronic control unit directly or through respective actuators, based on an electric signal indicative of an operating condition of intake valves on engine cylinders.

An intake apparatus for an internal combustion engine that has a first intake passage communicating with a combustion chamber of the internal combustion engine; a second intake passage which communicates with the combustion chamber of the internal combustion engine and whose length is greater than a length of the first intake passage; a valve for selectively changing over the communication/shutting off of the combustion chamber of the internal combustion engine with/from between the first or/and second intake passages; and a drive circuit for driving the valve to effect the changing over operation. A controller controls the drive circuit, and an air cleaner device introduces clean air into the combustion chamber of the internal combustion engine. The first and second intake passages are disposed inside a case of the air cleaner device, and the valve is disposed at a position which is prevented from interfering the outlet side of the second intake passage when the first intake passage is closed by the valve and the second intake passage is opened by the valve.

Provided are a ceramic-fine-particle producing process making it possible to produce, with ease, ceramic fine particles which have a spherical shape close to a complete round and an excellent mono-dispersibility, and are made only of a solid component of a simple ceramic material without making a fine channel structure complicated, and an apparatus used therein for producing ceramic fine particles. The process includes the step (S100) of feeding a dispersion phase made of an aqueous liquid containing a gelling agent to act upon cooling and a ceramic material into a continuous phase made of an oily liquid containing a surfactant, thereby producing fine droplets; the step (S110) of collecting and cooling the produced fine droplets; the step (S120) of washing the cooled fine droplets; the step (S130) of drying the washed fine droplets; and the step (S140) of firing the dried fine droplets.

A memory system permitting a number of alternative memory blocks to be made ready in order to extend the rewritable life and thereby contributing to enhanced reliability of information storage is to be provided. The memory system is provided with a nonvolatile memory having a plurality of data blocks in predetermined physical address units and a controller for controlling the nonvolatile memory in response to an access request from outside. Each of the data blocks has areas for holding a rewrite count and error check information regarding each data area. The controller, in a read operation on the nonvolatile memory, checks for any error in the area subject to the read according to error check information and, when there is any error, if the rewrite count is greater than a predetermined value, will replace the pertinent data block with another data block or if it is not greater, correct data in the data block pertaining to the error.

摘要:
A memory card includes a non-volatile memory, a memory controller for controlling the operation of the memory card. The memory controller is capable of providing an interface with outside according to a predetermined protocol, and performs error detection and correction of the memory information at regular time intervals or at the timing of connection of electric power supply, independently of reading out the memory information according to external access request. Therefore, it is possible to improve reliability of data retention in the non-volatile memory without the host device reading out the memory information from the non-volatile memory of the memory card.
摘要:
The reliability of data is significantly increased without considerably increasing costs by performing minor data corrections within an information storage device and performing major error corrections in an information processing device. When a request to transfer user data for reading is issued from an information processing device, a control circuit transfers the user data and management data to an error detection circuit, which checks the user data for errors. If the user data contains no error, the control circuit notifies the information processing device that the user data can be transferred, and transfers it to the information processing device. If the user data contains errors, an X count error position and correction data calculation circuit uses the user data and the management data to calculate correction locations and correction data, and judges whether the correction locations are correctable. If uncorrectable (there are more correction locations than X locations), the control circuit notifies the information processing device that the user data is uncorrectable, and then transfers the user data and the management data to the information processing device.

摘要:
A memory card has a plurality of non-volatile memories and a main controller for controlling the operation of the non-volatile memories. The main controller performs an access control to the non-volatile memories in response to an external access instruction, and an alternate control for alternating an access error-related storage area of the non-volatile memory with other storage area. In the access control, the speeding up of the data transfer between flash memories is achieved by causing the plurality of non-volatile memories to parallel access operate. In the alternation control, the storage areas is made alternative for each non-volatile memory in which an access error occurs.
