Patent number: 6454054Abstract: In an elevator, a transmission sheave is attached to a mount structure fastened to a guide rail. A speed governor rope suspended from a speed governor is coupled with an elevator car that ascends and descends in a shaft, and is wound on the transmission sheave. An idler pulley is provided for increasing a winding angle with respect to the transmission sheave by changing movement of the speed governor rope 4. A position detection apparatus is provided for detecting the position of the car in the shaft based upon the rotation of the transmission sheave. The position detection apparatus can be installed in an empty space in the shaft without the need of a repair of an existing speed governor to save the repair costs of the elevator.Type: GrantFiled: March 27, 2001Date of Patent: September 24, 2002Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Junichi Tanino, Masao Shibata, Ichirou Satou

Patent number: 5233292Abstract: A speed detector device capable of making speed measurements of an elevator in its relatively slow speed region comprises a pulse generator generating two-phase pulse signals with a predetermined phase difference between both signals, in a period according to the rotational speed of a motor, a pulse processing circuit for outputting corresponding triggers in response to the rising edge and the falling edge of each of the pulse signals generated by the pulse generator, a timer counter, latches for latching the output of the timer counter at the timing of the triggers, and calculating circuit for calculating the period of the pulse signals based on the timer counter output and for calculating the speed of the elevator based on the period calculated. The above arrangement allows data to be latched not only at the rising edge of the one pulse signal, but also at the falling edge of the same pulse signal and the rising and falling edges of the other pulse.Type: GrantFiled: May 21, 1992Date of Patent: August 3, 1993Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Yasuhiro Nagata, Junichi Tanino

Patent number: 5086450Abstract: An emergency intercommunication system for an elevator has an interphone unit and an intercommunication command switch located in an elevator car. A telephone number input apparatus for inputting the desired telephone number is provided in an elevator hall, in connection with a register apparatus for storing the input telephone number. An intercommunication command detecting section for detecting the actuation of the switch is provided in connection with an emergency call apparatus for automatically dialing the stored telephone number to connect the interphone unit with a telephone having the telephone number when the actuation of the switch is detected by the detecting apparatus. Preferably, an identification number input apparatus is provided in the elevator hall so that the register apparatus stores the telephone number only when it is input together with a predetermined identification number.Type: GrantFiled: August 17, 1990Date of Patent: February 4, 1992Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Shigeo Kitagawa, Kenzo Tachino, Yasuhiro Nagata, Tomoichiro Yamamoto, Shigemi Iwata, Terumi Hirabayashi, Junichi Tanino

Patent number: 5074385Abstract: A call registration apparatus for an elevator system includes a call registration lamp and a car call button disposed in an elevator car and connected by a common signal line to a CPU. When the call button is pressed a first time, the CPU registers a call and turns on the call registration lamp. When the elevator car reaches a floor, the CPU makes the call registration lamp flicker. If the call button is pressed while the lamp is flickering, the CPU performs a door opening or door closing operation.Type: GrantFiled: June 25, 1990Date of Patent: December 24, 1991Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Junichi Tanino, Hideyo Ujihara

Patent number: 5019960Abstract: A signal transfer system for an elevator including a master station and a plurality of slave stations, each slave station having provision for generating call signals and illuminating a call registratioin lamp. The master station generates a call registration signal in response to cage call and hall call signals. Each slave station also includes a timer which measures the time interval between transmission of a hall or cage call signal and a call registration signal. When the call registration signal is not received within a predetermined period of time, the respective slave station retransmits the hall or cage call signal. The call registration lamp is extinguished if the slave station has not received the call registration signal after a predetermined number of signal retransmissions.Type: GrantFiled: May 11, 1989Date of Patent: May 28, 1991Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Hiroshi Ando, Junichi Tanino

Patent number: 4846310Abstract: A signal transmission apparatus for an elevator in a multi-story building comprises a small number of signal lines which carry, in a time-shared fashion, hall call signal and hall call registration information for all floors. On each floor, one or more signal terminal means comprises one or more push buttons for entering hall calls and one or more indicator lamps for indicating that a hall call has been registered. A reference signal originates in a control unit and propagates through a ring counter with stages corresponding to each signal terminal means and each separate direction of travel, ascending or descending, supported therein. A signal indicating that a button on a given signal terminal means has been pushed is transmitted over a hall call signal line in synchronization with the reference signal to the control unit.Type: GrantFiled: May 10, 1988Date of Patent: July 11, 1989Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Junichi Tanino
