  • Patent number: 10794354
    Abstract: In an ignition control apparatus, a control unit controls switching elements so as to supply a primary current to the other end side of a primary winding opposite to one end thereof connected to a DC power source by discharging (which is performed by turning on a second switching element stored energy from a capacitor during ignition discharge (which is started by turning off a first switching element. In particular, the control unit controls the second switching element or the third switching element so as to provide variability to the amount of stored energy discharged from the capacitor according to an operating state of an internal combustion engine.

  • Publication number: 20200238545
    Abstract: A robot having joint shaft that includes: a first-link member and a second-link that are coupled about a rotation axis; a reducer that has an input-shaft fixed to the first-link and an output-shaft fixed to the second-link; a motor that generates a driving force to be input to the reducer; and an input-side encoder and an output-side encoder. The motor is away from the rotation axis, and a power transmission mechanism is provided between the motor and the reducer. The reducer includes a hollow-part and a tubular-member. The tubular-member passes through the hollow-part, one end of which is fixed to the input-shaft or the output-shaft, and the other end of which protrudes from the input-shaft or the output-shaft. The output-side encoder includes a scale and a sensor. The scale is fixed to the tubular-member; and the sensor is fixed to the input-shaft or the output-shaft.

  • Publication number: 20190189800
    Abstract: The disclosure reduces the risk of collapse of the wall surrounding the trench and suppresses the withstand voltage fluctuation that accompanies the manufacturing variation for a semiconductor device having a super junction structure. The semiconductor device includes a drift layer of a first conductivity type and a plurality of embedded parts embedded in the drift layer. The embedded parts are of a second conductivity type different from the first conductivity type, and the embedded parts are arranged with a first direction as a longitudinal direction and spaced from each other along a second direction that intersects the first direction. A width of each of the embedded parts in the second direction changes continuously along the first direction.

  • Patent number: 10161376
    Abstract: An ignition control apparatus for engines is provided. The ignition control apparatus is designed to control a switch to release energy stored in a capacitor during spark discharge, thereby supplying a primary current to an other end side opposite a one end of a primary winding of an ignition coil connected to a dc power supply. This provides the ignition control apparatus which is capable of minimizing an increase in size or manufacturing cost and stabilizing the state of combustion of an air-fuel mixture.

  • Patent number: 9822753
    Abstract: An ignition control device includes a control unit to control first to third switching elements so that during ignition discharge, which is started by turning off the first switching element, energy stored on a capacitor is discharged by turning off the third switching element and turning on the second switching element for supplying a primary current to an end of a primary winding opposite to an end thereof connected to a direct-current power supply. During inductive discharge of a spark plug, the control unit non-intermittently turns on the second switching element so that the second switching element is turned on over a successive energy input time period, according to the operating conditions of an internal combustion engine.
