IPC: H01L21/66
Filed: 2018-05-21
Abstract: To provide a manufacturing method of a SiC substrate capable of preventing yield reduction and device failure.SOLUTION: A CMP treatment is performed to a SiC substrate 1.

Title: Object detection sensor
Inventor: MATSUMOTO MASATAKA
IPC: G01F23/26
Filed: 2018-05-23
Abstract: PROBLEM TO BE SOLVED: To provide a capacitance type level sensor which is easy to adjust.MEANS: A counter 20 counts a high-frequency clock and divides its frequency and outputs a rectangular oscillation signal. The capacitance or inductance of a resonance circuit 26 changes in a state where there is an object 28 and in a state where there is no object, causing its resonance frequency to change. The frequency dividing number of the counter is gradually changed by frequency setting means 22 and the frequency of the rectangular oscillation signal is swept. The frequency setting means 22 acquires the amplitude of a detection signal when the frequency of the rectangular oscillation signal is changed. The rectangular oscillation signal is set to a frequency at which the amplitude is largest (or smallest). In this way, the frequency of the rectangular oscillation signal and the resonance frequency of the resonance circuit are automatically made to match.SELECTED DRAWING: Figure 1

IPC: F02P3/01
Filed: 2018-06-07
Abstract: PROBLEM TO BE SOLVED: To provide a system and method for controlling corona discharges and arc formations during a single corona event, i.e., intra-event control.SOLUTION: A driver circuit 30 provides energy to a corona igniter 20 and detects any arc formation.
