Patent number: 5263566Abstract: The present invention relates to a coin discriminating apparatus and method for discriminating genuine coins from counterfeit coins, and determining their denominations. And more particularly, the present invention purports to detect genuine coins based on the inherent difference in degree of peripheral thickening or convex configuration between genuine coins and counterfeit coins so as to provide a coin discriminating apparatus and method capable of preventing counterfeit coins from being used in an unauthorized or unfair way. In one specific example, there is provided a thickness detecting sensor 8 adjacent to a coin passage, and a coin face contour detecting apparatus 11 measures a time during which an output of the thickness sensor 8 exceeds a threshold value 22, thereby detecting degree of peripheral thickening or convex configuration of coins to discriminate genuine coins from counterfeit.Type: GrantFiled: April 1, 1992Date of Patent: November 23, 1993Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takehiko Nara, Toru Ueki

Patent number: 4749074Abstract: A coin sorting apparatus in which the oscillation constants of oscillators change with the passage of a coin, and the amount of change in each of the oscillation constants or a value converted therefrom is compared with a reference value of a coin to be identified which is stored in a memory to identify whether the coin is genuine and the class thereof. Whether the reference values for each coin are corrected is determined by a plurality of counters which correct the reference values of corresponding classes of coins when their counts exceed a predetermined set value. At the same time, when the inserted coin is identified as genuine, a corresponding counter is activated, thus improving the performance of eliminating spurious coins without reducing the acceptability of genuine coins even under ambient temperature changes or secular variations of component elements with time.Type: GrantFiled: October 11, 1985Date of Patent: June 7, 1988Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Toru Ueki, Shigeru Kakimi

Patent number: 4705154Abstract: A coin selection apparatus comprises a plurality of detection coils and an oscillation circuit which detects changes of impedances of the detection coils caused when a coin pass through the detection coils, as a change of a voltage output. The plurality of detection coils include at least two sets of detection coils each including two detection coils opposingly arranged to the coin path. One set of detection coils has its two coils connected in series and in phase and the other set of detection coil has its two coils connected in series and in phase opposition. The two sets of coils are arranged at a spacing along the coin path smaller than a minimum diameter of a coin to be selected and all of the coils are connected in series and connected as a resonance element of the oscillation circuit. Thus, material, thickness and diameter and other appearance characteristic of the coin are detected based on the voltage output of the oscillation circuit.Type: GrantFiled: September 23, 1985Date of Patent: November 10, 1987Assignee: Matsushita Electric Industrial Co. Ltd.Inventors: Yukio Masho, Shigeru Kakimi, Toru Ueki, Satoshi Miyauchi, Tugio Ohigashi, Hitoshi Kurohata

Patent number: 4617207Abstract: Disclosed herein are thermoplastic resin sheets having a thermal shrinkage within .+-.0.3%, and a process for producing thermoplastic resin sheets by co-extruding a first thermoplastic resin and a second thermoplastic resin which is nonadhesive to the first thermoplastic resin, into a sheet-like structure so that the first thermoplastic resin is covered on both surfaces thereof with the second thermoplastic resin and then peeling off the resulting outer layers of the second thermoplastic resin B to obtain a sheet of the first thermoplastic resin. The thermoplastic resin sheets obtained in accordance with the above production process have an extremely small thermal shrinkage, undergo an extremely low degree of mechanical strain, and exhibits a little optical anisotropy. Because of the small thermal shrinkage, they may be used in liquid crystal displays (LCDs), poultice or sticker.Type: GrantFiled: August 9, 1984Date of Patent: October 14, 1986Assignee: Mitsui Toatsu Chemicals, IncorporatedInventors: Toru Ueki, Yoshiaki Fukuda, Katsuyuki Usami, Kazuharu Kanasaki
