摘要： An optical distance measurement device for determining the distance to a object 5 exhibiting a bilateral symmetry, such as an automobile, includes two optical systems whose optical axes are separated by a lateral distance perpendicular to the axis of symmetry of the object 5. Two images are formed upon the image sensors 3 and 4. A window formed within each image having a width substantially corresponding to the width of the object 5 is successively shifted from left to right within the image, and the symmetry with respect to the central axis thereof is evaluated by the microcomputer 10 at each position of the window. The axis position at which the evaluated degree of symmetry is the greatest is determined for each image. The distance to the object 5 is determined from the amount of shift between the two axis positions, based upon the principle of trigonometry.

摘要： In a digital ramp phase type gyro in which a ramp signal RAM is produced by repeatedly accumulating step values sequentially generated corresponding to an input angular rate until the accumulated value exceeds a threshold value THR or -THR and the ramp signal RAM is used to modulate the phases of clockwise and counterclockwise light beams to cancel the phase difference therebetween, a comparing part 38 compares the threshold values THR and -THR and the ramp signal RAM and, when the ramp signal RAM exceeds either one of the threshold values THR and -THR, outputs the threshold value THR or -THR and a subtractor 41 subtracts the output threshold value from the accumulated value at that time, thereby causing a flyback of the ramp signal RAM. The output from a synchronous detector 23 at this time is latched as an error signal in a latch circuit 31 and the error signal is integrated by an integrating filter 32 to generate a correcting signal. The correcting signal is added to a reference value Er in a circuit 37 to produce corrected threshold values THR and -THR and the phase difference between the clockwise and counterclockwise light beams immediately prior to the flyback is always held to be 2n.pi. rad.

摘要： An apparatus for detecting the distance between one's car and the car ahead, together with the angle between the axes of the two cars. The apparatus has a pair of driving optical systems disposed at a predetermined distance from each other, each driving optical system comprising an optical system having a light projector which projects pulse light having a specific code toward the car which is ahead of the one's car and a light receiver which receives the reflected pulse light from the car ahead, the light projector and receiver being disposed in so close proximity to each other that the respective optical axes can be considered to be on substantially the same axis, and a driving system for adjusting the angle of projection of the light projector on the basis of a signal from the light receiver. The apparatus further has a central processing unit which measures the angle of projection of the pulse light from the light projector when the light receiver of each of the driving optical systems detects the reflected pulse light, thereby detecting the distance between the one's car and the car ahead, together with the angle between the axes of the two cars.

摘要： To reduce the air exhausted to outside a main body after cooling a heat generating component from being taken in again from an intake port. The flow of cooling wind cooled the heat generating component is discharged from an exhaust port 21 at other than a first peripheral wall 19 with the flow bent inside the main body. When rectified inside the main body and discharged from the exhaust port 21, the cooling wind grows to a flow speed of a certain extent to become an exhaust air that a flowing direction is clearly defined, so that it is less likely to be taken in again from the intake port 20, it is less likely to be subjected to the influence of obstacles of the exhaust port, use can be made in a kitchen cabinet of the intake and exhaust air at the back side, and it is satisfactory and is less likely to be damaged without involving sense of unpleasantness by the exhaust air to the user.
