Title: Corneal abrasion device
Inventor: NAKAMURA HIROTSUGU
IPC: A61F9/008
Filed: 1992-11-24
Abstract: PURPOSE:To prevent a stepped section from appearing at a boundary between an abraded zone and non-abraded zone by controlling a zone changing means in accordance with the shape of an adjusting zone, regarding a device for abrading the surface of a cornea to perform correction or the like of the curvature thereof. CONSTITUTION:A laser beam emitted from a laser beam source 10 is polarized via plane mirrors 11 and 12 and, then, projected to an ocular cornea 16 via an aperture 13 variable in opening diameter and working for limiting an abrasion zone, a projection lens 14 and a plane mirror 15. In this case, the plane mirror 12 is caused to reciprocate in a Z-axis direction synchronously with laser pulses, thereby causing the parallel displacement of the laser beam in the direction of Gaussian distribution and obtaining abrasions of equal depth. A control device 19 determines the shape of an adjusting zone for smoothly connecting an optical zone to a non-abraded zone on the basis of data from an input device 20, and controls the opening diameter of the aperture 13 on the basis of the adjusting zone.

Title: Ribbon removing method of winder
Inventor: OHASHI KENJI
IPC: B65H54/38
Filed: 1993-12-28
Abstract: PURPOSE:To disperse turn back points in traverse so as to increase prevention effect of a ribbon by varying rotation speed of a traverse drum so that a difference occurs between rotation speed of a package and rotation speed of the traverse drum and making the variation irregular. CONSTITUTION:When a traverse drum 2 is rotated in contact with a package 1 and a yarn is wound to the package 1 while traversing it, rotation speed of the traverse drum 2 is varied so that a difference occurs between rotation speed of the package 1 and rotation speed of the traverse drum 2. Also, the variation is made irregular so that turn back points in traverse are not arranged in parallel monotonously in the circumferential direction of the package 1. For instance, a switch drive section 7 turns ON and OFF a switch element 6, reads the time of ON or OFF from a time table 8, and changes over ON and OFF of the switch element 6 when the time shown by a clock 9 reaches the time of ON or OFF. The time table 8 may arrange random numerical values which show time intervals in advance and store them.

Filed: 1992-12-18
Abstract: PURPOSE:To decide exposure so that a main image such as a human face, etc., can be reproduced from the color original image of a negative film, etc., with optimum density. CONSTITUTION:Photographic information is read from the negative film and also the original image is divided into many picture elements so as to perform photometry, a noise in the data which is obtained by photometry is removed (100). Next, the picture elements of the original image having the similar data which is obtained by the phtometry are integrated (104), and as to each integrated area, an area which is drastically different from the size of the main image decided by the photographic information (photographic magnification) is removed (106). An effective area whose color is similar to that of the human face as the main image is extracted from the remaining original image area (108). The density of the human face is estimated with reference to all the extracted effective areas, and then, the photometric data having the density which is estimated as the human face is outputted (110).

Title: Front controller of wheel loader
Inventor: KOBAYASHI TORU
IPC: E02F3/43
Filed: 1992-12-18
Abstract: PURPOSE:To reduce the descending speed of the boom to mitigate the shocks on grounding of the bucket and also move up swiftly the boom to increase the working efficiency, by reducing the hydraulic oil flow rate or retaining it to the ordinary flow rate, when the boom moves down by the gravity and the front end of boom reaches a specified level above the ground or lower by turning a switch valve to the float position. CONSTITUTION:A boom cylinder 4 is provided with a switch valve 14 to change the flow of hydraulic oil. When the switch valve 14 is turned over to the float position F, the rod chamber of the boom cylinder 4 is connected to the bottom chamber thereof through a connection path 15. When the boom is lowered by the gravity to a specified height from the ground or lower at the front end of the boom, the flow rate of the hydraulic oil passing through the path 15 is decreased by a solenoid valve 22 and the descending speed of the boom is decreased. When the boom is lifted up higher than a specified level above the ground, the flow rate in the path 15 is retained as much as the ordinary rate. In this way, the shock of the bucket on grounding is mitigated and the working time is curtailed and further, the working efficiency can be increased.

Title: Security structure for circuit board
Inventor: TAKAHASHI KUNIMASA
IPC: A63F7/02
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To provide a security structure which is freely applicable, simply structured and low in manufacturing cost and which destroys the integrated circuit if the cover is opened. SOLUTION: Before a cover 48 is attached, the difference in level 44 in a free end piece 43 of a trigger 40 is engaged with an opening 42 edge of a case 12, preventing the pressed-movement of the trigger 40 and preventing hammer impact movement. With the attaching of the cover 48 causing a projection 50 inside the cover to push the free end piece 43, the engagement is released between the difference in level 44 and the opening 42 edge, making the difference in level 44 engaged with the projection 50.  If someone opens the cover 48 in order to come into contact with the integrated circuit for example with the purpose of illegally rewriting the data stored in the circuit, it releases the pressurizing by the cover 48, releasing the engagement of the projection 50 with the difference in level 44 and causing the pressed-movement of the trigger 40, which goes out of the case 12 and allows the hammer impact movement, so that a piezoelectric element 20 receives the impact to generate a voltage and that the integrated circuit is destroyed by the voltage thus generated.
