Title: Energy-absorbing bumper
Inventor: NAGATOMI KAORU
IPC: B60R19/18
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To provide an energy-absorbing bumper capable of highly reducing energy applied to a collided item on collision. SOLUTION: An energy absorber 3 is formed to a member exerting a shape in which its lower part is forwardly projected from its upper part. The result provides the energy absorber with the shape in which its lower part is forwardly projected from its upper part when the energy absorber collides with a columnar item which is bent at its intermediate point, for example. Thus, a position kept away from the bent part of a collided item comes to a colliding place, reducing force for generating the moment around the bent point. The result highly reduces the energy of the collision to reduce shock to the collided item.

Title: Character recognizing method and device therefor
Inventor: SHIBATA KATSUNOBU
IPC: G06K9/62
Filed: 1994-06-14
Abstract: PURPOSE:To provide a character recognizing method and device which can improve the recognizing efficiency of handwritten characters and also can increase the character recognizing speed. CONSTITUTION:A stroke input part 1 inputs the handwriting of characters to be recognized as the waveforms to show the continuous time changes of the X and Y coordinates, and a stroke normalizing part 2 normalizes these input waveforms. Then, a feature vectorizing part 3 extracts the partial feature value out of the normalized waveforms, and a hashing part 4 hashes the partial feature value to obtain the hash value. A weight totalizing part 6 and a recognizing candidate selecting part 8 select the recognizing candidates based on the hash value. A matching part 9 compares the partial feature value of the recognizing candidates with the partial feature value of various characters which are previously registered in a character feature vector data base 10 to secure the matching between both feature values. Thus the number of characters to be matched with each other can be decreased to some extent. As a result, the deterioration of the character recognizing efficiency can be suppressed and the character recognizing speed can be increased.
