摘要:
A breakerless ignition system for an internal combustion engine comprising an ignition power supply, a capacitance discharge type ignition circuit including a capacitance, an ignition coil and a first semiconductor switching means to discharge the capacitance through the ignition coil on the primary side thereof, and an ignition signal source to trigger the first semiconductor switching means to be turned on, the ignition system further comprising an ignition inhibiting means including a second semiconductor switching means arranged so that it periodcally prevents the ignition power from being applied to the ignition circuit when the speed of the engine becomes less than a predetermined value and also when the intake vacuum pressure of the engine exceeds a predetermined value.
摘要:
An ignition system for an internal combustion engine comprising a power supply, and an ignition circuit including an ignition coil having a primary coil portion connected to said power supply and a secondary coil portion connected to at least one ignition plug, said ignition plug disposed within an operating chamber of said engine and a contact breaker connected to said primary coil portion, said ignition system characterized by comprising means to override said ignition circuit and means to periodically effect the operation of said overriding means. Means to periodically effect the operation of said overriding means comprises a triggering signal generator to generate a triggering signal each time said contact breaker is operated, a frequency divider to divide said triggering signal from said triggering signal generator so as to produce a divided signal with the frequency of 1/n times that of said triggering signal wherein n is 2 or 4, with said overriding means receiving said divided signal for its operation and means to allow the operation of said overriding means only when said engine requires to periodically fail to ignite said operating chamber.

A recording-material cooling device includes a first cooling member, a second cooling member, an approach-and-separation member, and a positioning member. The first cooling member is disposed at a first face side of a recording material to absorb heat of the recording material. The second cooling member is disposed at a second face side of the recording material to absorb heat of the recording material. The approach-and-separation member brings the first cooling member and the second cooling member close to and away from each other. The positioning member positions the first cooling member and the second cooling member relatively brought close to each other by the approach-and-separation member.

A recording-material cooling device is disposed downstream from a fixing device in a transport direction of a recording material. The fixing device includes a fixing member and a pressing member to fix an unfixed toner image on the recording material. The recording-material cooling device includes a first cooling unit disposed at a same side as the pressing member relative to the recording material, a second cooling unit disposed at a same side as the fixing member relative to the recording material, and a third cooling unit disposed at the same side as the pressing member relative to the recording material. The first cooling unit, the second cooling unit, and the third cooling unit are arranged in an order of the first cooling unit, the second cooling unit, and the third cooling unit from upstream to downstream in the transport direction of the recording material.

In a forming apparatus, inner frames are arranged in a forming roll stand so as to move up and down. Mechanical structures of convexo-concave engagement are provided on opposed faces between respective roll chocks and yokes and the inner frames. After connection with a pressing device is released, the roll chocks and yokes are guided utilizing the moving-downward motion of the inner frames, and a stack body is formed in series so as to be withdrawn from the roll stand. The stack body is disassembled utilizing the moving-upward motion of the inner frames, and the roll chocks and yokes can be guided to the desired positions inside the stand and locked.
摘要:
A storage system including first storage devices constituting a first logical storage area, second storage devices constituting a second logical storage area; and a storage control apparatus. The storage control apparatus manages the first and second logical storage areas so that the data stored in the first and second logical storage areas have redundancy, and parity data for the data stored in the second logical storage area are stored in parity storage areas arranged in part of the second storage devices. When part of the first storage devices constituting part of the first logical storage area fail, the storage control apparatus generates part of the data stored, before the failure, in the part of the first storage devices, and stores the generated part of the data in at least part of the second parity storage areas in the second logical storage area.
摘要:
An apparatus using a battery includes a receiving unit, a determination unit and a calculation unit. The receiving unit receives a dischargeable capacity, a first voltage and a second voltage from the battery. The first voltage is used to display the end of an available time and the second voltage is used to carry out a low power operation. The determination unit determines whether the first voltage is less than the second voltage. The calculation unit corrects the dischargeable capacity and calculates the available time based on the corrected dischargeable capacity, if the determination unit determines that the first voltage is less than the second voltage.
