Title: Information recorder
Inventor: INOUE TAKAHIRO
IPC: H04N1/23
Filed: 1983-07-05
Abstract: PURPOSE:To attain the recording excellent in quality while making the effect of interference fringe unremarkable by modulating and driving a semiconductor laser by a driving current having harmonic components in a device recording information through the scanning of a photosensing face by a semiconductor laser light modulated by an information signal to be recorded. CONSTITUTION:When a picture signal 3 is inputted to a laser driver 2, a driving current flows to the semiconductor laser 1 in response to this picture signal, the semiconductor laser 1 is flickered by the result and outputted as an optical signal. When the picture signal is supplied, a driving current VD as the result of superimposition of a DC current on an AC current in several tens MHz - several GHz is applied to the semiconductor laser 1, which is suton and the semiconductor 1 is changed for the state from a normal oscillation. As a result, the number of oscillating wavelengths go to a plural. Assuming that the oscillated wavelengths of the laser light are two kinds as (a), (b), then the interference fringe produced by a photosensitive body goes to the superimposition of two kinds of interference fringes comprising the lights (a) and (b) and a pattern having less peaks and valleys than those of an interference fringe due to a light of a single wavelength is obtained.

IPC: G01S13/66
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To effectively suppress the number of hypotheses without lowering the performance of target tracking, concerning a target tracking device estimating the track of a plurality of targets. SOLUTION: A target observation device 11 detects the observation vector containing the position information of a target. An in-gate judging matrix calculation part 30 and a wake correlation matrix calculation part 34 calculate a track correlation matrix indicating a realizable state, by combining possibility of the observation vector of an erroneous signal and a possibility corresponding to a tracked target and a possibility of a new track. The target observation state estimation part 15 estimates the number of tracked targets and the total number of new tracks and erroneous signals, and judges the existence of erroneous signals and new tracks. A hypothesis renewal part 38 utilizes the processed results of the target observation state estimation part 15, and performs a simple processing for suppressing the hypothesis.

Filed: 1990-05-11
Abstract: PURPOSE:To immediately start data transfer by a DMAC generating a DMA transfer request by generating DMA permission signals to the plural DMACs by using a halt acq. signal from a CPU. CONSTITUTION:When detecting the H (high) state of a DMA request signal 2 by the starting edge of a clock, a DMAC 203 also outputs a halt request signal 2 and since loading a gate to a DMA permission signal 2 of the DMAC 203 by AND gates 210 and 211 according to a halt request signal 1 and a strobe signal 1 of a DMAC 202, however, the DMA permission signal 2 of the DMAC 203 is outputted after completing the DMA transfer of the DMAC 203. Afterwards, since the DMA permission signal 2 of the DMAC 203 is made effective, the DMA transfer is executed between the DMAC 203 and an I/O device 205 after opening the gate for one cycle. Thus, the DMA transfer can be executed at minimal time intervals while satisfying the setup/hold time of an address or data bus.

Title: Conversion circuit for voltage/current
Inventor: UCHIUMI YOSHIO
IPC: H03F3/45
Filed: 1980-09-03
Abstract: PURPOSE:To improve the linearity of a current by combining a differential amplification circuit with a current mirror circuit having two outputs and thereby removing the non-linearity of an amplifying element. CONSTITUTION:When input signals V1 and V2 are impressed on gates FET2 and FET5 through input terminals T1 and T2 respectively, the voltage between the gate and source of FET2 and FET3 and a drain current turn to be fixed constantly irrespective of the values of the input signals V1 and V2. As the result, the difference between the input signals V1 and V2 is generated at both ends of resistors 3 and 4 and thus a linear signal current (V1-V2)/(R1+R2) which is proportional to the difference between the input signals flows through the resistors 3 and 4. Accordingly, the linearity of the current being proportional to the differential voltage of a voltage impressed on an input can be improved by such a constitution.

Filed: 1978-10-05
Abstract: PURPOSE:To eliminate dead space looking from a driver's seat and prevent an accident due to a left-turning vehicle, by bending a glass plate having flat projections, cutting the bent glass plate to obtain a rear-view mirror which has no distortion and a nonuniform radius of curvature. CONSTITUTION:A glass plate 5 is cut off so that flat projections 6 are provided on the plate 5. The plate is then set on a baking mold of nonuniform radius of curvature so that the plate 5 is bent. As a result, a mirror whose radius of curvature ranges from 350mm at the top to 200mm at the bottom is manufactured. Since distortions 8 are produced on areas A, B due to the bending, the mirror is cut along lines 7A-7B, 7C-7D to eliminate the distortions. An integrally formed rear- view mirror having no distortion and a nonuniform radius of curvature is thus obtained. When the rear-view mirror is mounted on a vehicle by a fitted fixation ring, the rear view can be confirmed by a surface part of 600mm in radius of curvature and the view of the space just under the driver's seat can be confirmed by a surface part of 200mm in radius of curvature. Therefore, the range necessary for turning to the left can be checked.
