Filed: 2019-03-22
Abstract: To provide a pulse-width modulation control circuit capable of increasing the control precision without increasing an operating frequency.SOLUTION: A pulse-width modulation control circuit includes a first transistor and a signal generator. The first transistor includes a first terminal coupled to a power source, and a second terminal coupled to a first input of a controlled component. The signal generator includes a first node coupled to a gate of the first transistor. In the signal generator, the pulse-width modulation receives a comparison value 3322 and a comparison criterion 3324, 3326, and compares the comparison value to a counter value 3304 on the basis of the comparison criterion. In response to the comparison value satisfying the comparison criterion with respect to the counter value, a control signal is sent to the gate of the first transistor to generate a pulse edge of a pulse of a pulse-width modulated signal.SELECTED DRAWING: Figure 33

Title: Electronic component enclosure and electronic device
Inventor: MIYATA HIDEMITSU
IPC: H03B5/32
Filed: 2019-03-26
Abstract: To secure a large mounting area for an electronic component in an electronic component enclosure.SOLUTION: Side walls 20A and side walls 20B are formed along an outer edge of a backside of a substrate 10. Both side walls 20A and 20B are not formed all along the outer edge of the backside of the substrate 10 (rather than a frame), but formed with a portion of it broken off, which allows for a larger area of an IC 40 to be placed. In an electronic device 1 in this embodiment, a recess 13 is formed on a back-bottom surface 12 of the substrate 10, which is shallower than a thickness of the IC 40 and has a larger area than the IC 40. The IC 40 is bump-connected to a recessed bottom surface 16 of the recess 13. Continuously to the recess 13, injection portions 14, 15 of the same depth are formed. Although underfill is injected from the injection sections 14, 15 to a place between the recessed bottom surface 16 and the IC 40, since an exterior edge surface of the recess 13 is present, the underfill is prevented from leaking outside the electronic device (electronic component enclosure).SELECTED DRAWING: Figure 1

Abstract: To automatically search a pulse waveform so as to further reduce a sputter quantity.SOLUTION: A pulse waveform search device, has a generation part for generating waveform information for expressing a pulse waveform, an acquisition part for acquiring a sputter quantity generated when pulse arc welding is executed by using the pulse waveform expressed by the waveform information and a repetitive processing part for preserving mutually corresponding the waveform information and the sputter quantity in a storage part by repetitively executing pulse waveform generation and sputter quantity acquisition in this order. The generation part generates the waveform information expressed by a searched design variable by searching the design variable for expressing the waveform information so as to reduce the sputter quantity from a prediction value by determining the prediction value of the sputter quantity when each piece of the waveform information already preserved in the storage part is set as the design variable when newly generating the waveform information. The repetitive processing part extracts the waveform information which is made to correspond to the minimum sputter quantity from the waveform information in the storage part when a predetermined termination condition is satisfied.SELECTED DRAWING: Figure 1
