  • Patent number: 11399426
    Abstract: A wiring board and a method for manufacturing the wiring board in which an initial Cu plated layer is formed by plating so as to cover the surface of a metallized layer and then the initial Cu plated layer is heated to be softened or melted. Copper in the softened or melted initial Cu plated layer enters into open pore portions of the metallized layer. In addition, during the heating, components of the metallized layer and components of the initial Cu plated layer are mutually thermally diffused. Consequently, when solidified later (that is, when the initial Cu plated layer becomes a lower Cu plated layer), the adhesiveness between the metallized layer and the lower Cu plated layer is improved due to, for example, an anchoring effect and a mutual thermal diffusion effect.

  • Patent number: 11336267
    Abstract: Duty signal ratio and signal generation circuits with clock signal duty ratio stabilization under decreased power supply conditions are disclosed. In one example, a duty ratio correction circuit includes an inverting buffer, a capacitor, a low pass filter, an error amplifier, and an adjusting unit. The capacitor adjusts the rising and falling times of an inverted signal output from the inverting buffer. The low pass filter extracts a low frequency component of the inverted signal. The error amplifier adjusts a duty ratio of the inverted signal by controlling at least one of an output source current and an output sink current of the inverting buffer on the basis of a difference between the extracted low frequency component and a reference signal. The adjusting unit adjusts the control of the inverting buffer by the error amplifier.

  • Patent number: 11165343
    Abstract: An object of the present technology is to stably operate a power supply circuit. A charge switch is connected to a first terminal of a capacitor and charges the capacitor with an input voltage on the basis of a control signal inputted to a control terminal. A discharge switch is complementary with the charge switch, is connected to the first terminal of the capacitor, and discharges on the basis of the control signal inputted to the control terminal the voltage charged to the capacitor, thereby generating an output voltage. A charge control signal converting section converts a charge control signal that controls the charge into a control signal referenced to the input voltage and inputs the resulting control signal to the control terminal of the charge switch. A discharge control signal converting section converts a discharge control signal that controls the discharge into a control signal referenced to the output voltage and inputs the resulting control signal to the control terminal of the discharge switch.

  • Patent number: 11041535
    Abstract: A control apparatus for a synchronous meshing mechanism that is equipped with a gear, a sleeve, a synchronizer ring, and a hydraulic actuator is provided. When it is determined that the sleeve and the gear have been rotationally synchronized with each other in an engagement transition period of the synchronous meshing mechanism, an electronic control unit with which the control apparatus is equipped sets a command pressure for the hydraulic actuator to an intermediate pressure that is lower than a meshing completion pressure. Besides, when meshing has not been completed even after the lapse of a predetermined time from a timing when the command pressure for the hydraulic actuator is set to the intermediate pressure, the electronic control unit sets the command pressure for the hydraulic actuator to the meshing completion pressure.
