Abstract: A main journal 25a of a crank-shaped swinging shaft 25 which swings in a range of a predetermined angle is supported by bearing metals 51 and 52 each divided into two pieces. In supplying a lubrication oil through an oil bore 51b in the bearing metal 51 to a sliding surface of the main journal 25a and to inlet openings of lubrication oil passages P1 and P2 of the swinging shaft 25 open to the sliding surface, the inlet openings of the lubrication oil passages P1 and P2 of the swinging shaft 25 are designed so that they do not move past division portions 55 of the bearing metals 51 and 52 upon swing of the swinging shaft 25 in the range of the predetermined angle. Therefore, it is possible to prevent the lubrication oil to be supplied to the lubrication oil passages P1 and P2 from leaking from the division portions 55 of the bearing metals 51 and 52, thereby reliably lubricating a pin journal 25b of the swinging shaft 25 by the lubrication oil supplied from the lubrication oil passages P1 and P2.

Abstract: A controller for an electromagnetic actuator comprises a pair of springs acting on opposite directions, and an armature connected to the springs. The armature is held in a neutral position given by the springs when the armature is not activated. The actuator also comprises a pair of electromagnets for driving the armature between two end positions. In response to a release of the armature held in one of the end positions, the controller applies brake to the armature according to a load condition of the armature. In high-load conditions, the valve can surely be opened without additional electric power. In low-load conditions, the armature is prevented from colliding with a yoke of the electromagnet. The application of brake includes over-excitation operation, flywheel operation and suspension of power supply. In the over-excitation operation, voltage is applied to the electromagnet corresponding to one of the end positions from which the armature is released for a first period.

Abstract: A simulation coverage calculating apparatus is provided for calculating a simulation coverage for a complete verification. The apparatus includes a first input unit, a second input unit, an effective test pattern calculating unit, a coverage ratio calculating unit, and an output unit. The first input unit reads a property that represents effective test patterns to a logic circuit to be verified. The effective test pattern calculating unit calculates the effective test patterns based on the property. The second input unit reads the test patterns entered and executed by a verifier. The coverage ratio calculating unit calculates a coverage ratio from a ratio of the number of the test patterns matched to the effective test patterns to the number of all of the effective test patterns. The output unit outputs the calculated coverage ratio.

Abstract: It is found out that compounds represented by the formula (I): wherein R1 is an optionally substituted carbocyclic group or an optionally substituted heterocyclic group; and R2 and R3 taken together with the adjacent carbon atom form an optionally substituted heterocyclic group having one or more of oxo and/or thioxo; have an HCV RNA-dependent RNA synthase inhibitory effect.

Abstract: A portable terminal has one casing with a display unit and a speaker coupled to another casing with an operation unit and a microphone. The casings connect via a coupling unit and are capable of opening or closing by means of the coupling unit. The face of the casing with the speaker is directed in the same direction as the face of the casing with the microphone. The coupling unit enables one casing to be inclined to the other casing and to rotate around an axis substantially perpendicular to the face of the other casing with a microphone. Opening the casings increases the sound collecting rate of the microphone during a phone call and prevents a top face of the operation unit from being rubbed or scratched by the other.

Abstract: A humidity sensor is disposed near an HC adsorbent in an exhaust system of an internal combustion engine. After the internal combustion engine is shut off, it is detected whether or not the humidity sensor has failed based on the value of the humidity detected by the humidity sensor when the detected value of the humidity is substantially constant, by determining whether or not the detected value of the humidity falls in a range between upper and lower limit thresholds that are set depending on the temperature near the HC adsorbent. It is stably and easily detected whether or not the humidity sensor disposed near the HC adsorbent in the exhaust system of the internal combustion engine has failed.

The adsorbent deterioration determining apparatus comprises a humidity sensor arranged at a location downstream of the adsorbent in the exhaust system for detecting the humidity of exhaust gases, and an ECU for determining a deterioration of the adsorbent in accordance with a detected output of the humidity sensor at the time a predetermined time has elapsed from a start of the internal combustion engine.

Abstract: An exhaust gas purification system of internal combustion engine having a branch pipe coupled to the exhaust pipe through a flange and having a first cylindrical case constituting a bypass exhaust gas passage and a second cylindrical case constituting a main exhaust gas passage, whose flow are switched by a switch-over valve by selectively connecting the exhaust pipe to the main exhaust gas passage or the bypass exhaust gas passage, and an adsorbent installed in the bypass exhaust gas passage for adsorbing unburned components of the exhaust gas. The unburned exhaust gas components are recirculated to the air intake system through an EGR pipe. In the system, an inlet of the EGR pipe is formed integrally with the branch pipe flange, thereby enabling to prevent increase in fabrication step and cost and further to facilitate maintenance. Moreover, the first cylindrical case is made displace relative to the second cylindrical case.

Abstract: In an alternate energization process for alternately energizing a valve closing electromagnet and a valve opening electromagnet periodically, one of the valve opening electromagnet and the valve closing electromagnet is de-energized and thereafter the other electromagnet is de-energized at a time delayed by a predetermined time Toff. The alternate energization process is finished when the displaced position of a valve head which is detected by a displacement sensor has reached a predetermined position Vinit while the valve opening electromagnet is being energized. Thereafter, the valve opening electromagnet is continuously energized to seat the valve head in a closed position (initial position) from the time when the displaced position of the valve head has reached a predetermined position Vstart.

Abstract: An information input unit inputs functional configuration information representing a function of a device to be validated. A condition input unit inputs conditions concerning input/output sequence that is given to the device. A function generation unit generates a validation item function that fulfills all of the conditions based on the functional configuration information. An extraction unit extracts a combination of configuration elements that constitute the functional configuration information as a validation item based on the validation item function.

Abstract: A plurality of input signals to be input to a logic circuit, a verification object, is ranked depending on the degrees of influence the input signals have when vary on operation of the logic circuit. Verification is performed with a free pattern including all possible input patterns given to the input signals sequentially in descending order of the degree of influence. That is, the input patterns are sequentially generated according to preset conditions (the degrees of influence). Therefore, even when forced termination of the formal verification occurs due to insufficient memory of a verification apparatus, the obtained verification results can be kept based on the degrees of influence. This allows easy analysis on the causes of the forced termination, and improvement in verification efficiency. It is possible to estimate the time taken for the completion of the entire verification and the required memory capacity of the verification apparatus.

Abstract: A valve timing control system for an internal combustion engine is provided which is capable of ensuring reliable holding of a valve by an actuator, and attaining energy saving by efficient operation of the actuator. The valve timing control system controls valve-closing timing of a valve opened by a cam provided on a camshaft, by temporarily holding the valve. A response delay of the actuator is predicted as a response delay prediction value. Output timing is set in which a drive signal for driving the actuator is output, according to the predicted response delay prediction value. Holding timing is controlled in which the valve is held by the actuator, by outputting the drive signal to the actuator, based on the set output timing.
