Title: Method for measuring form change of a plurality of subjects in image
Inventor: YAMASHITA HIROYUKI
IPC: G06T7/20
Filed: 1993-08-31
Abstract: PURPOSE:To compare a subject to be measured in images differed in image pickup condition to automatically perform the conformation, and quantitatively measure the change of the subject to be measured such as a hair. CONSTITUTION:The same part of a testee is image-picked up in different image pickup conditions such as time to provide images A, B. An image processing part 12 to which the images are inputted binarizes the images to separate the hair from the background, and the respective areas and lengths of the hair images are measured. The position of the hair, or the coordinate group of the hair root is automatically measured. It is regarded that the position of the hair root is hardly changed in the same position of the same testee, the coordinate groups ai(axi, ayi), bj (bxj, byj) of the hair roots of the images A, B are mutually matched to determine the correction values DELTAx, of the whole image in which the slippage of the individual hairs is minimized. By use of these values, the conformation of the root hair coordinate with the corrected hair root coordinate (bxj-DELTAx, byj-DELTAy) is conducted. The combination of (i), (j) in which the distance between the hair root coordinate and the corrected hair root coordinate (bxj+DELTAx, vyj+DELTAy) is minimized is found to determine the difference with the determined length of the hair, whereby the growth of the hair can be determined.

IPC: B65H29/42
Filed: 1987-08-31
Abstract: PURPOSE:To smoothly perform continuous in-carrying of paper sheets by constituting a device of two or more spirals in the same direction alternately arranging deceleration conveying means, in case of the device which deceleratively conveys the paper sheets, continuously carried in along guide members, by the deceleration conveying means to be accumulated. CONSTITUTION:An in-carried mail 2 is held in its point end part 2a by edges 1a, 13a of the first and second guide members 1, 13 and a point P on the first spiral 22, being decelerated. In the midst of this deceleration, the second spiral 23, while rotating, feeds out the mail 2 to the right direction in such a manner as to pat the mail on its rear part side. That is, by deflecting the mail 2 in the right direction while decelerating, the following mail 2 is prevented from being adapted to the rear end part of the preceding mail 2. Further the first and second spirals 22, 23 perform a role of decelerating the mail 2 and that of extruding it to be changed in very half cycle. Thus preventing the following mail 2 from adapting its point end and a jam from being generated, the mail can be well accumulated.

Title: Detection of insertion of electronic component
Inventor: NAGANO KAZUAKI
IPC: H05K13/08
Filed: 1987-08-31
Abstract: PURPOSE:To realize an easy and secure method of detecting the insertion of an electric component by a method wherein, after the leads of a leaded electric component are inserted into the insertion holes of a circuit board and the leads protruding from the rear surface of the board are bent, the component holding force of a chuck is predetermined to be only the actuating force of an actuating means and, further, when the chuck is removed from the board and claws are closed, an open-and-close detecting means detects the closing state of the claws and confirms the insertion and, when the detecting means detects the opening state of the claws, the insertion failure is recognized. CONSTITUTION:As for an operation of confirming an insertion of electronic components, for instance, in the state wherein an air-chuck 7 is made to ascend while clinching claws 13 are closed, an electric component 14 is pressed against a board 16 by the clinching claws 13 and does not ascend with the air-chuck 7. If a solenoid 2 is operated, claws 10 and 11 are closed. At that time, a proximity switch 8 detects the facing claw 11 and is turned to ON state and the insertion is confirmed. If leads 17 are not inserted into predetermined insertion holes 18, the air-chuck 7 is made to ascend while it is holding the electric component 14. Even if the solenoid 2 is operated at that time, the proximity switch 8 can not detect the claw 11 because the component 14 exists between the claw 11 and the switch 8. Therefore, the insertion failure is recognized.

Title: Semiconductor light emitting device
Inventor: HATAGOSHI GENICHI
IPC: H01L33/14
Filed: 1990-08-20
Abstract: PURPOSE:To realize large extraction efficiency and obtain a semiconductor light emitting device of high luminance, by constituting a light extraction side electrode in a structure divided into a plurality of regions. CONSTITUTION:The title device is constituted of the following; an N-GaAs substrate 10, an N-In0.5(Ga1-xAly)0.5P clad layer 11, an In0.5(Ga1-yAly)0.5P active layer 12, a P-In0.5(Ga1-zAlz)0.5P clad layer 13, a P-GaAlAs current diffusion layer 14, an N electrode 15, and a P electrode 16. Since the resistivity of the P-GaAlAs current diffusion layer 14 is small as compared with the P-InGaAlP clad layer 13 is small, the current spread width can be remarkably increased. The electrode is divided into a plurality of segments, and, when the effective current spread width is Weff and the electrode width is W0, the following effect is obtained. That is, when the current density is small in the case of a single circular electrode, the effective current spread width increases, so that the current extraction efficiency eta is large when the current value I is small. When the electrode is divided into (m) segments, the current flowing each electrode becomes I/m, so that the value Weff/W0 can be increased. Thereby eta is improved while the total current value I is kept constant, and therefore a semiconductor light emitting device of high luminance can be obtained.

Filed: 1982-12-10
Abstract: PURPOSE:To attain a small-sized and high-sensitive sensor, by using an oxide crystal having optical Farady effect as a magneto-optic element. CONSTITUTION:The light emitted from a light source 1 reaches a polarizer 3b through an optical fiber 2 and is coverted to a linearly polarized light, and the plane of polarization is rotated at 45 deg. by the optical rotatory power of BGO (Bi12GeO20) constituting a magnetooptic element 4b while this linearly polarized light passes through the element 4b to reach an analyzer 5b; and at this time, if a magnetic field H acts upon the element, 4b, a rotation angle DELTAphi of the plane of polarization satisfies equation DELTAphi=(V2H+theta)l. In this equation, V2 is the verdet's constant of BGO, and theta is its optical rotatory capability. Since the Verdet's constant of BGO is 4-5 times as high as that of a lead glass, the rotation angle of the plane of polarization and the sentivity are 4-5 times high as those of a conventional sensor.
