Title: Light splitting type height measuring instrument
Inventor: HIZUKA TETSUO
IPC: H05K3/00
Filed: 1991-03-20
Abstract: PURPOSE:To improve the measuring accuracy of a light splitting type height measuring instrument which is used for visual inspecting devices for measuring the thickness of printed wiring conductors, etc., of printed wiring boards, etc. CONSTITUTION:The height of a point irradiated with light on a sample 2 is detected by dividing the light from the point irradiated with light into two parts at the edge section of a reflector 3a by means of a light splitting type height detector 3 and using the ratio of the difference between both parts to the sum of both parts. The brightness and height of the point irradiated with light are detected with a height/brightness detector 5 having a wider measurement range than the detector 3 has and an average substrate section height detecting means 6 finds the average height of a substrate section at every line on the sample 2 based on the detected value of the detector 5. A stage control means 7 drives a movable stage so that the output of the detector can fall within the measurement range based on the average values. An adding means 8 outputs the sum of the height corresponding to the position of the state 4 and the height measured by the detector 3 as the height of the point irradiated with light.

Title: Semiconductor laser and manufacture
Inventor: SUGAO SHIGEO
IPC: H01L29/861
Filed: 1991-02-28
Abstract: PURPOSE:To improve light emission characteristics of crystal and to improve characteristics by reducing dislocation density of a semiconductor laser whose substrate is silicon single crystal. CONSTITUTION:This semiconductor laser is provided with double hetero structure which is constituted of a buffer layer 7, an active layer 8 and a clad layer 9 in a sheet-like space between a lower insulating layer 2 having a single crystalline window 3 which exposes a silicon single crystal surface on a silicon substrate 1 and an upper insulating layer 6. The double heterostructure is in contact with the silicon substrate 1 by the buffer layer 7 through the single crystalline window 3. Dislocation is generated from the single crystalline window 3 wherein the silicon substrate 1 and the buffer layer 7 are in contact with each other; generally, it extends upward according to crystal face orientation which forms a certain angle with the substrate surface and stops at an upper insulating layer. As a result, when the lateral width of the buffer layer 7 is adequately large, dislocation does not attain the active layer 8, thereby reducing dislocation density of the active layer 8. Double heterostructure of good light emission quality can be acquired in this way.

Title: Obstacle detector for vehicle
Inventor: ASAYAMA YOSHIAKI
IPC: G06T7/00
Filed: 1993-03-18
Abstract: PURPOSE:To identify an obstacle accurately by providing a plurality of windows on an image pick-up screen with left and right image sensors, extracting the edge in horizontal direction, and then identifying the size of the obstacle according to the position of windows positioned at both edges and the distance from them to the target. CONSTITUTION:A plurality of windows are provided at a display 11 by a window setting means 12. When the image of a preceding vehicle 5 is captured on the image pick-up screen of a right image sensor 4, a microcomputer 10 obtains an image position which most matches a reference image signal from the image signal of a left image sensor 3 inside a memory 8 with the image inside the window catching the image inside a memory 9 as the reference image signal. At this time, the distance from each window to the preceding vehicle 5 can be calculated from the amount of shift of picture element and pitch and then the base line length between the lenses 1 and 2 and a focal point distance. A horizontal edge extraction means 13 obtains the edge in horizontal direction of the image inside the screen. Both terminals of the edge become a plurality of windows and then the side width and height of the driving vehicle 5 can be calculated from the distance between the windows and the distance to the driving vehicle 5.

Title: Optical recording and reproducing method
Inventor: OBA HIDEAKI
IPC: G11B17/028
Filed: 1989-03-10
Abstract: PURPOSE:To suppress vibration caused during the rotation of a disk by sticking a charged plate-like or sheet-like member closely to an optical recording medium surface on the opposite side of a side irradiated with a laser beam, etc. CONSTITUTION:The plate-like or sheet-like member 61 is made an electro- statically charged state on its surface to be abutted on the disk 1 and fitted closely to the disk. Plastics and glass, etc., are preferable for the material of the member 61. Thus, when the plate-like or sheet-like member 61 is under the charged state, an electric field is thereon effective, and the adherence between the member 61 and the disk 1 becomes quite well. However, since the plate-like or sheet-like member 61 is placed under the attractively adherent state merely owing to the charge, and is rotated together with the disk 1, its weight and thickness are naturally restricted. By this method, fine vibration can effectively be prevented at the time of rotating the optical recording medium.
