摘要:
To improve resolution of a built-in A/D converter by reducing the area occupied by a chip of the built-in A/D converter in a semiconductor integrated circuit that is mounted in an on-vehicle millimeter wave radar device and which incorporates an A/D converter and an MPU. In the semiconductor integrated circuit, a plurality of reception signals of the radar device is A/D-converted by a single digital correction type A/D converter. The digital correction type A/D converter of the single A/D converter is a foreground digital correction type A/D converter that sequentially A/D-converts the reception signals output from a multiplexer of a receiving interface. The single A/D converter includes a pipeline type A/D converter having a plurality of cascade-coupled converters. The semiconductor integrated circuit comprises a correction signal generating unit, a digital correction D/A converter, and a digital correction unit for digital correction.

A quinoline-3-acetic acid derivative of the formula ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are the same or different and each is a hydrogen atom or a halogen atom, R.sup.4 is a hydrogen atom, a halogen atom or a substituted or unsubstituted lower alkyl, R.sup.5 is an optionally esterified carboxyl and the broken line means an optional presence of a double bond, and a pharmaceutically acceptable salt thereof. The novel compound of the formula (I) and a pharmaceutically acceptable salt thereof of the present invention have an aldose reductase inhibitory activity in mammals inclusive of human and are highly safe. Accordingly, they are useful as pharmaceutical compositions for the treatment of the complications of diabetes, such as faulty union of corneal injury, cataract, neurosis, retinopathy and nephropathy, particularly cataract and neurosis.
