Abstract: The present inventions provides a generated-voltage regulator for an automobile, in which the on state of a key switch can be detected securely without being affected by a change in ambient temperature or the like. According to a selected embodiment, when a generation failure occurs in a power generation circuit 12, a power MOS FET 111 is turned on and off periodically so that a charge lamp 3 is lighted. The on/off state of the MOS FET 111 is detected by a detecting section 1121 of a voltage detecting circuit 112. Being supplied with an on signal from the detecting section 1121, a holding section 1122 turns the level of its output signal c to an "H" level only for a predetermined period. As a result, the key switch 2 is not judged to be off even in the case where the MOS FET 111 is turned on, and the on state of a switch 116 is maintained.

Abstract: A process for the separation of liquid component mixtures by combined pervaporation-vapor permeation with a feed flow in the form of a vapor-liquid mixture being employed and the feed flow being passed from bottom to top as a vapor-liquid mixture over a vertically arranged membrane, so that a permanent thorough mixing of vapor and liquid results, and no stationary liquid film is able to form on the surface of the membrane.

Abstract: A MCAV optical disc read/write system with a postscript type of recording medium is, which uses a pit edge method of recording information in spiral physical tracks of the medium. The spiral physical tracks are grouped into logical tracks in which a single track address is assigned to each logical track. The logical tracks in turn are grouped into circumferential zones. The number of physical tracks constituting a logical track in adjacent circumferential zones, and the number of track sectors per logical track are set such that the increment in the number of sectors per physical track in proceeding from an inner one to an outer one of such zones is controlled to minimize rate changes in the read/write clock frequency at zone boundaries. Sector addresses thereby may be read even when a read/write head is positioned in a wrong one of adjacent zones.

Abstract: A liquid sample automatic analyzer is achieved in which if any test strip is not placed at a photometric position for such a reason that a test strip automatic supply device has failed to supply the test strip, this failure is detected to enable automatic judgment on that the measured results of examination correspond to which samples. A presence/absence detector is provided in the test strip automatic supply device, and a pressure detector for detecting whether the test strip is gripped or not is provided in a grip device. Detection signals from the presence/absence detector and the pressure detector are supplied to a control unit. Based on those detection signals, the control unit determines a failure in taking out or gripping the test strip, if occurs.
