Patent number: 4653107Abstract: Coordinates of a handwritten pattern drawn on a tablet are sequentially sampled by a pattern recognition unit to prepare pattern coordinate data. Based on an area encircled by segments created by the sampled pattern coordinate data of one stroke and a line connecting a start point and an end point of the one-stroke coordinate data, the sampled pattern coordinate data of the one stroke is converted to a straight line and/or curved line segments. The converted segments are quantized and normalized. The segments of the normalized input pattern are rearranged so that the input pattern is drawn in a predetermined sequence. Differences between direction angles for the rearranged segments are calculated. Those differences are compared with differences of the direction angles of the dictionary patterns read from a memory to calculate a difference therebetween. The matching of the input pattern and the dictionary pattern is determined in accordance with the difference.Type: GrantFiled: December 24, 1984Date of Patent: March 24, 1987Assignee: Hitachi, Ltd.Inventors: Hiroshi Shojima, Soshiro Kuzunuki, Kotaro Hirasawa

Patent number: 4411338Abstract: In an elevator system in which an elevator car serves a plurality of floors in response to hall calls and cage calls, the number of, for example, up hall calls originated from, for example, the 2nd floor is counted, and the number of cage calls, classified by destination floors, registered in the elevator car after the elevator car has served each of the up hall calls is also counted. The count of the hall calls and the count of the cage calls classified by destination floors are compared with each other, and, on the basis of the result of comparison, the probabilities of origination of cage calls, classified by destination floors, which will be registered in the elevator car after the elevator car has subsequently served a new up hall call which would be originated from the 2nd floor, are calculated for forecasting future cage calls.Type: GrantFiled: September 25, 1981Date of Patent: October 25, 1983Assignee: Hitachi, Ltd.Inventors: Soshiro Kuzunuki, Kotaro Hirasawa, Takeo Yuminaka, Kanji Yoneda

Patent number: 4367811Abstract: In an elevator control system, in which the elevator car is controlled on the basis of elevator car positions obtained through the counting of distance pulses provided in proportion to the distance travelled by the car and floor height data indicative of the heights of individual floors, the distance pulses are counted by moving the car at a low speed from the lowest floor to the highest floor, and the count at the time of the actuation of a floor position detector, which is actuated when the car passes by each floor, is stored as the floor height value of that floor in a RAM (Random Access Memory). With this arrangement, the measurement of the floor heights is facilitated, and also the preparation of a ROM (Read-Only Memory) for storing the floor height data for each elevator car is made needless to promote the standardization.Type: GrantFiled: February 20, 1981Date of Patent: January 11, 1983Assignee: Hitachi, Ltd.Inventors: Kenji Yoneda, Kazuhiro Sakata, Takeo Yuminaka, Masao Nakazato, Tomiaki Kurihara, Soshiro Kuzunuki, Yasunori Katayama

Patent number: 4350225Abstract: A control logic for an elevator servicing a plurality of floors of a building comprises two microcomputers. The two microcomputers are provided with abnormal state detectors of their own. When the abnormal state detector of one microcomputer is actuated, the elevator is operated for recovery to the nearest floor by the other microcomputer on the condition that the abnormal state detector of the other microcomputer is not actuated, and thereafter retrial for the abnormal microcomputer is effected by an instruction from the other microcomputer. When the abnormal microcomputer recovers to normal state by the retrial, the elevator keeps operating, thereby preventing such a problem that the elevator cannot continue service by erroneous operation due to noise.Type: GrantFiled: January 31, 1980Date of Patent: September 21, 1982Assignee: Hitachi, Ltd.Inventors: Kazuhiro Sakata, Takeo Yuminaka, Masao Nakazato, Kenji Yoneda, Soshiro Kuzunuki, Yasunori Katayama
