    • Provided is a control apparatus for an internal combustion engine which controls the internal combustion engine in such a manner as to prevent excessive overshoot of an actual phase angle at a time of phase angle feedback control. The control apparatus for an internal combustion engine includes: a unit for detecting an actual phase angle of a camshaft based on a crank angle signal and a cam angle signal; a unit for setting a target phase angle of the camshaft based on an operational state; and a unit for performing phase angle feedback control calculation such that the actual phase angle coincides with the target phase angle, to calculate an amount of operation for the hydraulic pressure control solenoid valve, in which: the phase angle feedback control calculation is started for a first time after a KEY is turned ON with an initial value of an integral term set to a predetermined value; the phase angle feedback control calculation is performed using a control gain obtained by multiplying a control gain at a time of normal control when a control difference is equal to or larger than a preset value during the phase angle feedback control; and the phase angle feedback control calculation is performed using the control gain at the time of normal control when the control difference is smaller than the preset value during the phase angle feedback control.

    • Respective positive terminal electric potentials of exhaust gas sensors are sequentially selectively inputted to an analog input terminal of a multi-channel AD converter through a multiplexer. An offset voltage is applied to respective negative terminals of the exhaust gas sensors. This offset voltage is inputted to another input terminal of the multi-channel AD converter. A microprocessor detects a generating voltage of the exhaust gas sensors by the difference between a digital converting value of the positive terminal electric potential and a digital converting value of the negative terminal electric potential. The microprocessor also individually judges that each of the digital converting values is excessively small and excessively large. Thus, the microprocessor judges the existence of ground, sky short circuit and disconnection abnormalities of the negative terminal and the positive terminal.
    • 废气传感器的正极端子电位通过多路复用器依次选择性地输入到多通道AD转换器的模拟输入端。 对排气传感器的各负极施加偏移电压。 该偏移电压被输入到多通道AD转换器的另一个输入端。 微处理器通过正极端子电位的数字转换值与负极端子电位的数字转换值之差来检测废气传感器的发电电压。 微处理器还单独地判断每个数字转换值过小和过大。 因此,微处理器判断负极和正极端子的接地,天线短路和断线异常的存在。

    • Systems, methods and circuits for implementing efficient device testing. As one example, a method is disclosed for testing a device that includes both a digital and analog portion. In some cases, the digital portion includes a plurality of latch devices, and the analog portion includes a plurality of memory cells and a plurality of selector devices. Each of the plurality of selector devices is electrically coupled to a respective one of the memory cells, is at least indirectly coupled to one of the plurality of latch, devices, and is controlled by a selector input. In the method, a load clock is applied to the plurality of latch devices such that a pattern is loaded into the plurality of latch devices. The selector input is asserted such that a derivative of the pattern is received by the plurality of selectors and returned to the plurality of latch devices. A system clock is applied to the plurality of latch devices such that the derivative of the pattern is loaded into the plurality of latch devices.

    • During an operation to change the recording speed, an optical pickup (3) is retracted so as to play back a signal that has already been recording onto a disc D. A synchronization signal obtained from the signal that is played back by the optical pickup (3) and a recording reference signal are synchronized, and the recording operation is resumed from a recording interrupted position. The position where the optical pickup (3) is to be retracted is set on the basis of the time required to change the recording speed. Also, a rotational speed change operation for a spindle motor (1) for rotationally driving a disc D and the retract operation for the optical pickup (3) are performed concurrently.
