IPC: G01B11/02
Filed: 1978-06-12
Abstract: PURPOSE: To perform size measurement without being affected by the vibrations, thickness change and inclination of the target object by forming bright and dark parts on both sides of the target object with a projecting means, picking up the images of the bright and dark parts and target object and operating the coordinates of both ends in the size measuring direction of the target object.  
     CONSTITUTION: A target object 1 is placed on a table 8. Light is then projected from a projector 7 which is so arranged that its divergent point comes on the optical axis of a camera 2. The image of the target object 1 is picked up with the camera 2 and the video is obtained in a monitor 5. At this time the portions Tu, VN of the shade of the target object 1 created on the table 8 are also picked up and their images are obtained in the monitor 5. From the video electric signals of this monitor, formula [I] is operated in a processing unit 6, whereby the size W in the width direction of the target 1 is obtained.

IPC: H04R9/02
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To provide an inner core type magnetic circuit for speaker in which deficient magnetic flux in a magnetic gap is eliminated. SOLUTION: A caption 1 indicates a yoke, a caption 2 is a magnet A, a caption 3 is a magnet B, a caption 4 is a pole, a caption 5 is an upper yoke, a caption 6 is a side yoke and a caption 10 is a the entire magnetic circuit. Two sides of the magnets A2, B3 opposed to each other are of the same pole to form a repulsion magnetic field. The side yoke 6 is fixed to one bottom side of the yoke 1 and one end of the upper yoke 5. The magnetic flux from the magnet A2 passes through the pole 4, the magnetic gap (g), and the yoke 1. The magnetic flux from the magnet B3 passes through the pole 4, the magnetic gap (g), the yoke 1, the side yoke 6 and the upper yoke 5. Since the flux from the two magnets passes through the magnetic gap (g), a sufficient magnetic flux density is obtained.

Title: Method of etching semiconductor crystal
Inventor: KATOU YOSHITAKE
IPC: H01L21/3065
Filed: 1993-03-30
Abstract: PURPOSE:To make an etching surface a mirror surface without using corrosive gas, and have excellent controllability of an etching speed, and further use a prior art MOCVD, MBE device as it is, when etching a semiconductor crystal. CONSTITUTION:An organic metal gas is used as etching gas. Dimethyl zinc (DMZn) received within a bubbler 1a is bubbled with H2 and flows at 50mumol/ min within a reaction tube 11. All carrier flux is set at 5000sccm. A GaAs substrate 12 is etched at 0.11mum for 20min, and an etching speed is 5.6nm/min with excellent controllability. An etching surface is a mirror surface with no damages. It is presumed that this is because DMZn is resolved on the GaAs substrate to obtain methylradical CH3*, which reacts to Ga or As on the uppermost crystal surface to evaporate as Ga(CH3)n or As(CH3)n. Also, the organic metal gas is not corrosive.

Title: Abnormality detection controller of electric power steering system
Inventor: KANI AKIRA
IPC: H02P29/00
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To integrate a failure detecting mechanism and an assist inhibiting mechanism by decting a failure by directly comparing steering torque with assist torque as a mechanical displacement and controlling an assist inhibition by mechanically making a power source nonconductive simultaneously with this failure detection. SOLUTION: The lever 57 of a low speed comparing part fits into the groove of the sleeve of a first detector detecting steering torque, and first and second electrodes 52, 53 axially move according to displacement of the sleeve. A brush 54 for low speed moves via a push-pull wire 64 according to displacement of a proportional solenoid detecting assist torque. When assist torque is too much larger than steering torque, the brush 54 for low speed advances more quickly than the second electrode 53. Therefore, when the brush 54 for low speed reaches a fail area, the brush 54 for low speed passes the second electrode 53 and moves on an insulated substrate 51, a power source becomes a disconnected state and a failure is detected.
