Title: Overload preventive device for motor
Inventor: ISHIDA KAZUO
IPC: H02P3/06
Filed: 1987-04-30
Abstract: PURPOSE:To protect a motor positively from burning due to overload by turning a motor base, overcoming the elastic force of an elastic member while stopping power supply to the motor immediately after the state of overload is brought and excess tension is applied to the motor. CONSTITUTION:When a motor 4 is rotated, a conveyor 12 is driven through a chain 11. Since tension applied to the motor 4 through the chain 11 is made smaller than elastic force by a spring 8 during a time when the conveyor 12 is operated within the range of predetermined load fluctuation, a motor base 1 is not revolved, and the motor 4 continues stable revolution. When the state of overload, in which the conveyor 12 receives restraint and is stopped, is brought and excess downward tension is applied to the motor 4 through the chain 11, the motor base receives revolving torque, using a node shaft 2a for a link 2 as a fulcrum, and the driven side section 1b of the motor base 1 is lifted, overcoming the spring 8. A limit switch 10 is operated by the driven side section 1b at that time, and a power supply is interrupted.

Title: Pattern collation device
Inventor: NAKAJIMA HIROSHI
IPC: G06F17/14
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To improve the collation precision of patterns by collating a registered pattern with a collation pattern based on the intensity of the correlative component of each of data forming the N-dimensional pattern data on the correlative component area emerging in the synthetic Fourier N-dimensional pattern data that undergone the N-dimensional discrete Fourier transform. SOLUTION: A fingerprint collation (two-dimensional pattern collation) device consists of an operation part 10 and a control part 20. The part 10 includes a ten-key 10-1, a display 10-2 and a fingerprint sensor 10-3. The two-dimensional discrete Fourier transform is applied to the image data on the collation fingerprint. Thus the collation Fourier image data are produced and synthesized with the register Fourier image data on the registered fingerprint that undergone the two-dimensional discrete Fourier transform. Then (n) pixels of higher orders having high intensity of correlative components are extracted out of a correlative component area emerging in the synthetic image Fourier data through the amplitude suppression processing and the two-dimensional discrete Fourier transform.  Then the average intensity of correlative components of those extracted (n) pixels is referred to as the correlative value and compared with the threshold value. Thus the registered fingerprint is collated with the collation fingerprint.

Title: Controller for variable speed drive system
Inventor: OKAMATSU SHIGETOSHI
IPC: H02P29/40
Filed: 1994-05-23
Abstract: PURPOSE:To improve follow-up to a speed command by computing a required value of the input or outlet current from the operating command signal and the load characteristics of an electric motor, and setting it as the output value of an integrator or the primary delay factor in a voltage control part. CONSTITUTION:Torque increases with the square of the speed in an electric motor, so it is possible to obtain a current command value which maintains speed at the time of restarting operation as an output when a speed command value is inputted in a square-law operating device 27 with coefficient. The current command value is inputted in a switch 28, and is set as the output of the operating device of a proportional integrator 17 during stopping. Because a required value to maintain a speed is given beforehand as the output of the proportional integrator 17 generated at the time of restarting operation, response delay is shortened, and the current required to maintain a speed is injected with only the response delay of the proportional integrator 20 for current control. It is thus possible to enhance the speed response characteristics of an induction motor 7 and improve it regardless of the response characteristics of the proportional integrator 17 for voltage control.
