Abstract: A semiconductor device relating to the present invention comprises a base layer of an N-type impurity region. In the base layer, trenches are provided. In the each trench, a gate insulating film and a gate electrode are formed. A body layer of a P-type impurity region is formed in contact with the trenches, and in parallel adjacent to the base layer. On the main surface of the body layer, an emitter layer of an N-type impurity region is provided. On the main surface of the body layer, a contact layer of a P-type impurity region is provided spaced from the trenches. The emitter layer and the contact layer are exposed in different regions on the main surface of the body layer. A buried layer of a P-type impurity region is formed spaced from the trenches in closer to the base layer than to the contact layer in the body layer.

Abstract: A corneal surgery apparatus capable of reducing parts where a corneal curvature suddenly varies, and an apparatus for determining a corneal ablation amount. The corneal-ablation-amount determining apparatus includes a data input unit which inputs data on a correction amount of a patient's eye and data on a size of a second ablation zone for connecting a first ablation zone for securing the correction amount with a non-ablation area, a calculation unit which divides the inputted correction amount into at least ten, obtains an ablation amount for each divided correction amount as a lens component is ablated according to a size gradually enlarged from the first ablation zone to an outer diameter of the second ablation zone for each divided correction amount, and determines a total ablation amount by summing each obtained ablation amount, and an output unit which outputs data on the determined ablation amount.

Abstract: In an environment monitoring system for a vehicle, when a detecting means decides that an approaching vehicle cannot be detected by an image processing means, a waning means gives warning of this fact. Thus, the environment monitoring system permits one's own vehicle to run with safety even when the approaching vehicle cannot be detected.

Abstract: In a rear monitoring system for a vehicle, the information on the road on which one's own vehicle has run is acquired. On the basis of the information thus acquired, the white lines on a rear road image which distinguish one's own lane from both adjacent lanes are estimated. Using the white lines thus estimated, it is decided whether another detected vehicle is located on one's own lane or adjacent lanes.

Abstract: A medical data managing system includes: a recording unit which is able to record patient data including identification data on a patient and inspection data; a display; a reception input unit which inputs reception data on the patient; and a control unit which displays, on the display, at least part of the patient data and at least one of reception time and an elapse time from the reception time with linking each other.

Abstract: A vehicle-applied rear-and-side monitoring system wherein a monitoring area is set inside or outside an area enclosed with lines connecting two lane marking positions, where two lane markings on both sides of a preceding vehicle running lane in the road image cross a periphery of the road image, to an infinity point in the road image, which infinity point corresponding to a detected rudder angle. Further, a vehicle-applied rear-and-side monitoring and alarming system which a alarms a drives when the following vehicle was detected as a result of monitoring a rear-and-side road view by was of the vehicle-applied rear-and-side monitoring system.

Abstract: In a rear monitoring apparatus for a vehicle, a prism (2) enlarges the lower portion of the range which can be picked up by a camera (1), and a usage means uses the lower portion. In this configuration, the image in the vicinity of one's own vehicle can be picked up without impeding the detection of the optical flows generated from another vehicle approaching from a far distance, and can be used for the purpose different from the detection of the optical flows.

Abstract: A rear-view monitor for use in vehicles is provided, in which contained are vehicle-mounted image pickup means for picking up images of road in the rear of one's own vehicle at every fixed time; and detection means for detecting an overtaking vehicle by processing road images obtained by the image pickup means. The monitor keeps monitoring of relative movement between one's own vehicle and the overtaking vehicle detected by the detection means. The monitor is characterized in that the image pickup means contain a wide-angle high resolution camera, and the detection means include: first image processing means for processing the whole road images obtained by the image pickup means by sampling image data; second image processing means for processing a part of road images obtained by the image pickup means without sampling image data; and selection means for selecting either the first image processing means or the second image processing means in response to a situation of traffic.
