  • Patent number: 8044624
    Abstract: A load control apparatus outputs a PWM signal to a switching element to control a load. The switching element is connected between a power supply and a grand in series with the load. An abnormal increase detecting unit outputs an abnormal increase detection signal when detecting abnormal increase in applied voltage, which is applied to the load, relative to target voltage. An abnormal decrease detecting unit outputs an abnormal decrease detection signal when detecting abnormal decrease in the applied voltage relative to the target voltage. An operating state monitoring unit outputs a normally operating signal when the load normally operates. A signal combining unit generates a combined signal by combining the abnormal increase detection signal, the abnormal decrease detection signal, and the normally operating signal and outputs the combined signal via a common signal output terminal.

  • Patent number: 8043549
    Abstract: An object is to reduce the axial dimension of an injection apparatus (31), facilitate the work of removing and inserting a screw (20), and improve the quality of molded products. The injection apparatus (31) comprises a heating cylinder (17), a screw (20), and a drive apparatus. The screw (20) includes a plasticizing portion which includes a body portion (45a) and a flight (53) projectingly formed on an outer circumferential surface of the body portion (45a). An index ?, which is obtained by dividing a value obtained by adding a screw stroke S and a screw effective length L together by the screw stroke S, satisfies the relation 2.0<?<4.5. Even when the screw (20) is shortened, resin can be melted satisfactorily. Accordingly, the axial dimension of the injection apparatus (31) can be reduced.

  • Patent number: 7100368
    Abstract: In a secondary air injection system, MOSFETs control supply of electric current to an air pump and to a motor for driving an electromagnetic valve and to an electromagnetic coil to introduce secondary air into an exhaust gas passage upstream of a catalyst for purifying the exhaust gas of an internal combustion engine. Gate drive circuits control the MOSFETs based on an instruction from an ECU via input signal processing circuits. Abnormal conditions in the operation for controlling the air pump and the electromagnetic valve are detected, and, when an abnormal condition is detected, forcibly turn the MOSFETs off to interrupt the current to the motor and to the electromagnetic coil. A diagnosing circuit sends to the ECU diagnosis signals representing the state of controlling the load.
