Title: Decision method for alignment of two line segment strings
Inventor: HASEGAWA HIROSHI
IPC: G06T7/60
Filed: 1990-03-09
Abstract: PURPOSE:To accelerate decision for similarity by calculating a total area as dividing the overlapped area of two line segment strings into triangular areas, and calculating mean distance between the line segments set as criterion for the similarity. CONSTITUTION:The line segment string targeted to decide the similarity consists of the one in which plural line segments a0, a1,... defined by a pair of start point and end point specified by (X,Y) coordinates are connected and the one in which plural line segments b0, b1,... are connected. Firstly, the overlapped area setting the start point of the line segment a0 and a point where the orthogonal component of the point crosses with the line segment b1 as start terminal side, and the end point of the line segment b3 and a point where the orthogonal component of the point crosses with the line segment a3 as termination side is extracted. Next, the length of the center line of the overlapped area is calculated, and the total area is calculated as dividing the overlapped area into the triangular areas. After that, the mean distance between the line segments is calculated based on the length of the center line and the total area of the overlapped area. Alignment between the two line segment strings can be decided setting the size of calculated mean distance as reference, which accelerates the decision for the similarity.

Abstract: PURPOSE: To prevent a clutch plate from coming in contact with a rotating member at interlocking the clutch by a method wherein a guide member is provided on the clutch plate and the rotating member is made up so that said guide member can be guided slidably in the direction of an output shaft.  
     CONSTITUTION: In a powered lawn mower, when an operating lever 111 is revolved in the direction of arrow A, its bent parts 11a, 11a push a pressure plate 6 downward against the force of a spring 9. Accordingly, a clutch spring 35 expands, the clutch plate 26 and the disk plate 15 are interlocked in a unitary body and a working cutter blade 40 is rotated by the rotation of the output shaft 4. In this case, three projections 36 are formed on the peripheral edge of the clutch plate 26 and a guide member 37 made of glass fiber-containing resin etc. is attached to each projection 36. On the other hand, cavity parts 38 are formed on the side wall of the rotating member 31 at the locations corresponding to said projections 36 and the guide member 37 is guided keeping a predetermined clearance C between the guide member 37 and the cavity part 38.

IPC: G11B7/24
Filed: 1991-03-20
Abstract: PURPOSE:To prevent dirt on an optical disk face with simple construction by providing plural blades on either an optical disk side or a spindle side. CONSTITUTION:In an optical disk device provided with a clamping mechanism on the upper end of a spindle provided for a disk driving part which is used to mount the optical disk 2 on the spindle by means of a hub 22 at the center part of the optical disk, when the optical disk 2 is rotated, a blade provided on either the side of the optical disk 2 or the spindle forms an air flow along a laser light incident surface. As a result, the opportunity for dust contained in the air to adhere to the laser light incident surface can be reduced. Even when the dust adheres, it is blown out of the optical disk surface by lamina air flow which stays all time and thus, the dirt on the optical disk surface can be prevented.

Title: Electron microscope using field emission electron gun
Inventor: OOI MASAMICHI
IPC: H01J37/28
Filed: 1991-03-20
Abstract: PURPOSE:To obtain an electron microscope using field emission electron gun capable of stably performing a gain control operation even at the time of selecting accelerating voltage. CONSTITUTION:The current amount of electron beam generated at a field emission electron gun 1 is detected by a throttle plate 14. When accelerating voltage in the aforesaid electron gun 1 is changed from Va1 to Va2, a time for an amplifier 16 to start a gain control operation is delayed by a time T for accelerating voltage to become stable. This time T must be changed, depending upon the values of the voltage Va1 and Va2. In the time T after the selection of the accelerating voltage, the amplifier 16 performs a gain control operation and a signal therefrom is fed to a division operation circuit 10, thereby causing the start of a noise cancellation operation.

IPC: G06Q20/18
Filed: 1993-02-23
Abstract: PURPOSE:To obtain nearly normal correction data and accurately discriminate paper money by using another sensor even if the paper currency has an absence at its edge. CONSTITUTION:When the optical pattern, etc., of a medium 1 are read out by using plural sensors 3-1-3-4, one sensor 3-1 is set as a sensor for correction data extraction first.

In this case, another sensor 3-3 is selected as the sensor for correction data extraction. Consequently, accurate read data on a no-pattern part of the medium 1 are obtained and a read signal is properly corrected.
