Patent number: 11914075Abstract: A distance measurement apparatus includes: a laser light source configured to emit emitted light to be applied to an object to be measured; a laser light source control circuit configured to control the laser light source; a MEMS mirror configured to two-dimensionally scan the object with the emitted light; a reflecting member configured to cover a part of a scan region, and reflect the emitted light; and a light detector configured to receive reflected light from the object to be measured and reflected light from the reflecting member, and output a received light signal. The laser light source control circuit sets, to a threshold value, an amount of the emitted light obtained when output of the light detector is saturated, and controls an amount of the emitted light such that the amount of the emitted light is less than the threshold value.Type: GrantFiled: June 19, 2019Date of Patent: February 27, 2024Assignee: Mitsubishi Electric CorporationInventors: Yosuke Takagawa, Masahiro Kawai

Publication number: 20120273972Abstract: Mounting a power supply ring-shaped conductor and a ground ring-shaped conductor within the innermost circumferential ring-shaped area enclosing the semiconductor chip and within the ring-shaped region adjacent to the outer side of this innermost circumferential ring-shaped region when mounting the semiconductor chip on the substrate package, makes the chip more resistant to noise but also conversely causes the problem of increased cost and size for the entire semiconductor device. The power supply pad and ground pad are here clustered in the outermost ring-shaped area on the semiconductor chip. The power supply terminal and ground terminal are clustered on the innermost ring-shaped region enclosing the semiconductor chip. This placement reduces the size and manufacturing cost of the overall semiconductor device.Type: ApplicationFiled: April 20, 2012Publication date: November 1, 2012Applicant: Renesas Electronics CorporationInventor: Yosuke KAWAI
