Latest Patents
Yamashita's latest patents include a gate driver designed for driving a switching element and a power converter that integrates the gate driver and an output element into a single chip. The gate driver features an edge detection circuit, an ON pulse generation circuit, first and second OFF pulse generation circuits, and a status hold circuit. The first OFF pulse generation circuit generates a first OFF pulse in response to the leading or trailing edge of a control input signal, which is detected by the edge detection circuit. The status hold circuit drives an output element in response to the ON pulse outputted from the ON pulse generation circuit and maintains the driving status of the output element until a first OFF pulse is generated. Additionally, the second OFF pulse generation circuit generates a second OFF pulse in response to a protective operation signal, which is supplied to the status hold circuit to stop the driving of the output element. Another notable patent is for an oil pan designed for internal combustion engines. This oil pan collects lubricating oil drained from the engine and oil dripped from the crankshaft. It includes a shallow oil collecting portion, a deep oil collecting portion, and baffle plates that form first and second oil passages, facilitating the efficient collection of lubricating oil.
