IPC: H01L29/788
Filed: 1992-06-09
Abstract: PURPOSE:To prevent an oxide film from being deteriorated at the time of the erasing operation of a flash EEPROM and to reduce a current consumption. CONSTITUTION:A control gate electrode 1 and a substrate 7 are respectively set at a GND level, a source region 3 is set at a high-voltage level, a drain region 4 and a substrate 6 are set at an open level and a substrate 5 is set at a high-voltage level, whereby a tunnel current is generated between a floating gate electrode 2 and the region 3 and an erase is conducted by emitting electrons from the electrode 2 to the region 3. A potential difference between the region 3 and the substrate 5 is set so as to decrease to a level that an interband tunneling is not generated between the region 3 and the substrate 5. Thereby, the improvement of repeat write characteristics of a nonvolatile semiconductor device and the operation of a 5-V single power supply are made possible. Moreover, as a negative potential is not required, a complicated circuit becomes unnecessary, a structure for ensuring the breakdown strength of the source region part becomes unnecessary and the manufacturing process of the device is simplified.

IPC: G06T1/00
Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To estimate the area of a dead angle even when there is the dead angle in an image-pickup area in a system monitoring road by means of plurality of cameras. SOLUTION: The monitoring cameras 10 are arranged along the advancing direction of the road. An object such as a vehicle 100 is extracted from the image obtained by each camera and extracted data is sent to a next camera. Each camera estimates the number of objects estimated to presently exist in the image picking-up section based on past object data photographed by itself and past object data sent from a preceding camera, and compares it with the number of the objects actually extracted from the image. When the number of both objects are not coincident with each other, it is judged that a defective vehicle stops or a new vehicle joins the flow of vehicles in the area of the dead angle between respective image pickup areas.

Title: Solid-state image pickup device
Inventor: WATANABE FUMIO
IPC: H04N5/335
Filed: 1983-08-17
Abstract: PURPOSE:To enable to inject a fixed quantity of stable change at all times for variation of potential of a CCD by detecting quantity of injected change contained in an output signal and controlling IS potential to make the quantity of injected charge always constant. CONSTITUTION:An IS, an input gate (IG), a horizontal BCCD113, an output amplifier 114, a sample and hold circuit 501 and a comparator 503 constitute a feedback loop. When the IG is fixed to constant DC voltage and horizontal BCCD driving pulse voltage is fixed to a constant value, the qunatity of injected charge is proportional to voltage of the IS. As injection of charge is made in the period of stoppage of the horizontal BCCD113, level difference conrresponding to the difference of the quantity of injection is caused between the part where injection is not made and the part where injection is made in output signal waveform. This level difference is detected and held by sample and hold circuits 501, 502, and added to the comparator 503. IS voltage is controlled to make the output of the comparator 503 constant at all times.

Abstract: PURPOSE:To make an allowable value with respect to the tracking dislocation of a main beam large by irradiating an optical card with a spot so that a long elliptic cross sectional shape in the width direction of a recording zone is provided. CONSTITUTION:A collimator lens 3, a beam splitter 4 and an objective lens 5 are coaxially disposed in the optical path of light 2 emitted from a semiconductor laser 1 as a light source. The objective lens 5 has an elliptic contour which is smaller than the contour of the emitted light 2. The emitted light 2 which is passed through the objective lens 5 and which has the elliptic cross section is focused on the track 10 of the optical card 6 as the spot whose major axis is adjusted to the width direction and whose minor axis is adjusted to the track direction being the longitudinal direction. In such the case, the whole of the width of the track 10 is irradiated by the elliptic spot 12 and the allowable value of about 1/10 of the length is secured by setting the length of the major axis, that means, the width of the track 10 which is sufficiently longer than the diameter of a pit 11, as a reference. Thus, a sufficient allowable amount with respect to the dislocation of the track 10 is obtained.
