A control apparatus for an internal combustion engine can detect knocking of the engine even when an extraction frequency band is switched in accordance with an operating state of the engine. The apparatus includes a knock sensor for detecting vibrations generated in the engine and outputting a vibration detection signal, a rotation sensor for detecting the engine operating state, a SCF circuit for extracting a signal of a specific frequency band from the vibration detection signal and outputting an extracted vibration signal, a filter frequency switching section for switching an extraction frequency band of the filter section in accordance with the engine operating state, and a knocking detection section for detecting knocking of the engine based on the extracted vibration signal. The filter frequency switching section inhibits switching of the extraction frequency band until a switching inhibition period elapses after the switching of the extraction frequency band.

In some examples, an electrode plate K is conveyed to a gap 230 of a pair of stacking drums 210 and 220 with a conveying section 100. In synchronization with conveyance of the electrode plate K, the drums 210 and 220 feed a pair of separators S each formed into a predetermined shape with the separators S adhering to corresponding peripheral surfaces of the pair of drums 210 and 220. While feeding the electrode plate K forward in a generally horizontal manner, the separators S are sequentially stacked on both surfaces of the electrode plate K in synchronized with rotations of the drums 210 and 220, and both edge portions of the separators S are welded.

A display device includes an electrode layer formed at a predetermined position on a substrate, an insulating film having a through-hole formed on the top of the electrode layer, and a wiring film connected to the electrode layer via the through-hole formed in the insulating film. Based on a surface of the substrate, the through-hole includes a first taper portion having a first taper angle, a second taper portion formed higher than the first taper portion and having a second taper angle different from the first taper angle, and a third taper portion formed higher than the second taper portion and having a third taper angle different from the second taper angle.

A parallel mechanism has a plurality of arms. Each of the arms has a ball joint. The ball joint includes a ball stud with a shaft portion and ball-shaped head, and a socket swingably and pivotally movably holding the ball-shaped head of the ball stud. The socket includes a semispherical recess portion holding the ball-shaped head from a top portion to an equator thereof, and an extending portion which is smoothly continuous with the semispherical recess portion and which extends from the equator of the ball-shaped head to the shaft portion side. The inner diameter of an opening in the extending portion is equal to or larger than the diameter of the ball-shaped head.

A parallel mechanism includes a base, actuators attached to the base, a plurality of arms coupled together in parallel, and a sensing device. Each of the arms has a first link, one end of which is coupled to the actuator, a second link through which the other end of the first link and a bracket are coupled together, a ball joint through which one end of the second link and the other end of the first link are swingably coupled together, and a ball joint through which the other end of the second link and the bracket are swingably coupled together. Each of the ball joints includes a ball stud including a ball-shaped head, a socket swingably holding the ball-shaped head of the ball stud, and a conductive member interposed between the ball-shaped head and the socket. The sensing device senses when at least one of the plurality of ball joints is loose, based on whether or not the ball stud and the socket are electrically continuous with one another.

In a vehicle-mounted electronic control device having a switching power supply in which a switching element is controlled to obtain a predetermined intermediate voltage Va stepped down from a vehicle-mounted battery, and to which a downstream side coil, a flywheel diode, and an output capacitor are connected to suppress a pulsating voltage, a circuit for suppressing reverse conduction for the switching element is provided in order to prevent that the switching element is reversely conducted and thus a charging voltage of the output capacitor is abnormally lowered when a power supply voltage Vb of the vehicle-mounted battery is abnormally lowered.

A parallel mechanism includes a base portion, a bracket to which an end effecter is attached, a plurality of actuators attached to the base portion, a plurality of arms through which the plurality of actuators and the bracket are coupled together in parallel, and a control device arranged to control the actuators. When the end effecter in a stopped state is moved to a target position, the control device is arranged to control the actuators so that a level of acceleration at which the end effecter is accelerated is higher than a level of deceleration at which the end effecter is decelerated.

An electronic control apparatus is provided in which a supervisory control circuit part capable of mutual communication with a main control circuit part, which is operated by a high speed clock signal of high precision, is operated by a medium speed clock signal, which is low in cost and precision, such that they can operate mutually independently of each other. The main control circuit part supplies a medium speed communication synchronization signal frequency divided to the supervisory control circuit part. The supervisory control circuit part is operated by the medium speed clock signal to supervise the control operation of the main control circuit part. An error measuring circuit calculates an error correction coefficient which is the ratio of the signal cycle of the communication synchronization signal to that of the medium speed clock signal. The value of the error correction coefficient is reversely supervised by the main control circuit part.
