Latest Patents

One of his latest inventions is a programmable sequence controller that enables the display of the contents of a storage means for storing input and output data to and from a machine. This device allows numerical values to be set in the storage device from an external unit. The programmable sequence controller utilizes a sending and receiving unit for exchanging commands and other data with a numerical control device, facilitating the transfer of display content and numerical values. This innovation allows the contents to be displayed on the numerical control device's display means and permits the setting of numerical values entered from a data setting means.

Another significant patent is a programmable sequence controller that does not require a tape reader for reading a paper tape bearing a punched sequence program. In this system, a prepared sequence program is punched in a paper tape according to the standards of a paper tape reader provided in a numerical control device. The program is then transferred from the numerical control device to a random access memory in the programmable sequence controller. This allows the sequence program to be read from the random access memory, enabling the execution of sequential operations by processing the program.
