摘要： In a control apparatus and method for controlling an intake air quantity for an internal combustion engine, a throttle position of a throttle valve installed in an intake system of the engine is controlled in such a manner that an intake pressure around the throttle valve (pressure difference between upstream and downstream sides of the throttle valve or a ratio of a pressure between the upstream and downstream sides of the throttle valve) is maintained constant at an approximately predetermined negative pressure under a predetermined (low) engine load condition and a valve closure timing of at least one intake valve installed to open and close each corresponding combustion chamber of the engine is simultaneously controlled to regulate an intake air quantity supplied to the engine under the predetermined (low) engine load condition.

摘要： In a semiconductor memory device in which cell arrays are connected to a shared bus line through sense amplifiers at the time of reading-out and writing operations, a sub-amplifier is provided between two bus lines, the sub-amplifier amplifying a potential difference of reading-out data fetched on the bus lines from the selected sense amplifier and a potential difference of writing data input to the bus lines from the outside. The sub-amplifier has an ability to amplify the potential differences of both of the reading-out data and writing data on the bus lines without separating the bus lines, whereby the amount of delay due to wiring can be reduced.

摘要： Apparatus is provided for reproducing either M channels of digital audio signals recorded in longitudinal tracks on a record medium or an analog audio signal recorded in one or two stereo tracks. M heads are used to reproduce the M channels of digital audio signals and N of those heads (N.ltoreq.M) are used to reproduce the analog audio signal. The reproduced digital or analog audio signals are multiplexed and digitized. When digital audio signals are reproduced, the digitized multiplexed signals are digitally processed and then converted to analog form. When analog audio signals are reproduced, the digitized multiplexed signals are summed such that signals reproduced by the N heads are combined to form a digital representation of the recorded analog audio signal. The summed signals then are converted to analog form to recover the original analog audio signal.

The valve is of the type which is held in a neural position, i.e., in a partly open position when an electromagnetic actuator is not energized. When the valve fails in opening, the supply current is increased than that at normal times to drive the valve to close, whereby to prevent misfire, backfire and a bad influence to intake conditions of other cylinders and thereby attain an elongated service life of engine parts. A failsafe control method is also provided.

摘要： A synchronous semiconductor memory comprises a memory controller receiving a pre-CAS signal and a test-CAS signal for outputting the test-CAS signal as the CAS signal when a mode discrimination signal is active to indicate a test mode, and the pre-CAS signal as the CAS signal when the mode discrimination signal is inactive. A data amplifier controller receives the CAS signal and a clock signal and generates a data amplifier enable signal in time with the clock signal when the mode discrimination signal is inactive. This data amplifier control generates the data amplifier enable signal by delaying the CAS signal when the mode discrimination signal is inactive. In response to a column selection signal, data stored in the memory cell array is outputted to associated data amplifiers. When the associated data amplifiers are enabled by the data amplifier enable signal, the data outputted from the memory cell array is amplified and outputted by the associated data amplifiers.

摘要： A spray head (30) for an applicator (1) for applying biological tissue bonding agent to an affected area, where the bonding agent is produced by spraying and mixing solutions respectively received in a pair of syringes (2 (2a, 2b)). The spray head (30) has a first nozzle opening (42a) from which the solution received in either one (2a) of the syringes is jetted in a predetermined jetting direction, and also has a second nozzle opening (42b) from which the solution received in the other syringe (2b) is jetted in the direction same as or substantially the same as the predetermined jetting direction. The second nozzle opening (42b) is placed forward in the jetting direction from the first nozzle opening (42a). In applying the biological tissue bonding agent, which is formed by simultaneously spraying the first solution received in the first syringe and the second solution received in the second syringe and mixing them together, onto an affected area, a clogging of the nozzle openings from which the first and second solutions are jetted can be prevented, and as a result, intermittent application of the bonding agent can be reliably performed.
