IPC: G06T7/00
Filed: 1991-04-19
Abstract: PURPOSE:To register original feature points other than dummy feature points with priority by evaluating plural 'windows' formed in the vicinity of an extracted feature point at the time of registering a finger print. CONSTITUTION:A feature point is extracted from an input image (binary image) stored in a binary memory 3 by a feature point extracting part 12 and plural 'windows' segmented from the vicinity of the feature point are registered in a feature information storing part 5. Then a picture element value comparing part 10 collates the registered 'windows' with the plural 'windows' segmented from an input image positioned around the registered windows. When both the 'windows' coincide with each other, the number of times of coincidence is calculated. Then a using order setting part 20 registers the 'window' having less coincidence frequency with priority.

Title: Unfair shot detector
Inventor: TAKEMOTO TAKATOSHI
IPC: A63F7/02
Filed: 1997-05-06
Abstract: PROBLEM TO BE SOLVED: To detect a game player's continuous unfair single shot. SOLUTION: An incoming ball count means 12 counts the number of game balls collected from a prize winning port or an outlet arranged on a game board surface as the incoming ball number. A unit incoming number calculating means 14 sequentially obtains the number of incoming balls per unit time (e.g. one minute) according to the count value of the incoming ball count means 12. A comparing means 16 compares the incoming ball number per unit time with a designated reference number, and an unfair shot determining means 20 determines the unfair shot when the period the incoming ball number per unit time is smaller than the reference number continues more than fixed time. For example, although it is usually 100, when the period the incoming ball number per unit time is less than 40 continues for three minutes or more, an intentional single shot is detected.

Title: Piano handle-type switch
Inventor: UENO SATORU
IPC: H01H21/00
Filed: 1990-05-02
Abstract: PURPOSE:To improve returning force of a slide cam to the center and at the same time improve reliability of the returning as well by installing a slide cam with a specific shape to provide contra-rotating force to a contra-rotatable handle while sliding in the back side of a push-button handle. CONSTITUTION:When a push-button handle 32 is pushed down by pushing down one end part of a piano handle 43 using a supporting part in the other end part as a supporting point, a contra-rotatable handle 31 is contra-rotated through a slide cam 33 in the lower plane side of the push-button handle 32. When the pushing of the piano handle 43 is released, the push-button handle 32 returns by a returning means, so that one end side of the piano handle 43 rises while pushed by the push-button handle 32 and returns to the original position. At that time, the slide cam 33 returns to the center position owing to the elastic returning force of spring 33a unitedly formed with the slide cam 33. Moreover, since the slide cam 33 is formed like a square shape, deformation at the time of assembly is prevented.
