Title: Character recognizing method
Inventor: EJIRI KOUICHI
IPC: G06K9/00
Filed: 1983-12-26
Abstract: PURPOSE:To obtan a high recognition factor for both handwritten characters and type characters by referring to the value obtained by averaging the square sums of all feature variable constants in order to discriminate the handwritten and type characters from each other. CONSTITUTION:The variances DELTAx, DELTAy, DELTAz... from a dictionary variable constant Pd to each of feature variable constants (x, y, z...) and a variance DELTAR between the Pd and the data R obtained by integrating all said feature variable constants are compared with the threshold value respectively. Then the threshold levels DELTAxB, DELTAyB, DELTAzB... and DELTARB of handwritten characters are set in an initial state. A dictionary is retrieved for each feature variable constnt extracted from characters to be recognized to extract the differences smaller than the prescribed value by means said threshold values of handwritten characters and to define them as the first candidate characters. Then these characters are checked to obtain a distance DELTAR from the Pd for each feature variable constant. This distance DELTAR is compared with the threshold value DELTARB to obtain the distance DELTAR, and the sum total of DELTAR is obtained by a register AD. This obtained sum is divided by the character number to obtain the mean value of distance DELTAR.

Title: Safety speed variation sensor
Inventor: AREN BURIIDO
IPC: H01H35/14
Filed: 1992-08-27
Abstract: PURPOSE: To obtain a safe sensor for detecting a speed change inexpensively by bending a first contact means toward a second contact means in response to deceleration by an inertia member. CONSTITUTION: A safety sensor 12 can be arranged on the refractory wall of a car and upper blades 50, 52 energize a spherical member 34 to bring the same into contact with a wall 30. A sensor 12 is arranged so that the spherical member 34 is energized in the direction shown by an arrow A when a car is decelerated. When this deceleration is larger than a predetermined threshold value, deceleration force overcomes the energizing force and the spherical member 34 is protruded in the direction shown by an arrow A along a passage 40 to come into contact with the leading end parts of the blades 50, 52. The spherical member 34 bends the blades 50, 52 in the same direction when moved in the A-direction until the blades 50, 52 come into contact with bent parts 58, 60.  Therefore, electric circuits are formed between the blades 48, 50 and 46, 52 and these passages are used in the generation of an electric signal. These signals are sent to the sensor 12 from a plug 94.

Abstract: PROBLEM TO BE SOLVED: To prevent a fatigue disconnection of a wire material caused by floating and to realize a long life by using a twisted copper wire or braided copper wire for a short-circuiting wire material for connecting a movable T-formed contact piece to a supporting piece, laying the wire material in parallel to a short piece of the movable contact piece at the nearest part of the abutting part of the movable contact piece on the supporting piece and spot-welding one end of the wire material. SOLUTION: A wire material 50 comprising a soft twisted copper wire is layed in parallel to a short piece 33 of a movable contact piece 30 at an approximately nearest part of the abutting part 34 of the movable contact piece 30 on an abutting part 41 of a movable contact piece-supporting piece 40 and an end 51 of the wire material 50 is spot-welded to the movable contact piece 30. The wire material 50 is layed in parallel to a longitudinal side 43 of the movable contact piece-supporting piece 40 and an end 52 is spot-welded to the supporting piece 40.  Thus, the floating of the wire material 50 by an opening/closing action of a power switch and a generation of a fatigue disconnection are suppressed to enhance a durability by short-circuiting both pieces at the nearest part of the abutting part of the movable contact piece 30 and the supporting piece 40 with the wire material 50 of a soft twisted copper wire or a braided copper wire having a durability. The wire material 50 can bear even against one hundred thousand times or more of opening/closing actions.
