Title: Data sampling method
Inventor: SUZUKI KUNIHIRO
IPC: G01H3/00
Filed: 1984-06-07
Abstract: PURPOSE:An actually required wave form is represented as that in a higher standard of precision, by making a high-speed Fourier conversion section longer than that required to be displayed on its wave form, even if distortions are invided on both ends of a reversed high-speed Fourier conversion space after the reversed high-speed conversion process. CONSTITUTION:Distortions are represented as B. High-speed Fourier conversion FFT section T, and reversed high-speed Fourier conversion iFFT section W start earlier and end earlier than a wave form display section C the wave form of which being required to be represented. Further, aforesaid wave form display section C does not include the distorted portions of the iFFT wave form 4. Consequently, a displayed wave form 5 reproduces the wave form of the original actual signal 2 without distortion. Setting of this particular time is available by setting of a sampling trigger 1. Thus, a wave form can be displayed under less influence of distortions and of high precision.

Abstract: PURPOSE:To eliminate the time for the reinput and to reduce the load of an operator by offering the contents set to a register means as well as the Japanese reading of KANJI (Chinese character) set to a buffering means when the selection of KANJI is requested with the keyboard input. CONSTITUTION:The input data and the control data are supplied from a keyboard 1. The data equivalent of one character is stored in a keyboard register 2 and a character buffer 3 holed the input character data until a KANJI conversion key is pushed through the keyboard 1. A KANJI deciding circuit 4 detects the push of the KANJI conversion key and sends this detection result to a dictionary retrieving circuit 5 together with the output of the buffer 3. The circuit 5 detects the data having the same Japanese reading out of a dictionary memory 6 or a dictionary file 7 and stores it to a dictionary memory reading register 8. A buffer 10 stores temporarily the data of the buffer 3. When the request is given for the selection of KANJI with the keyboard input, not only the contents set to the register 8 but the Japanese reading set to the buffer 10 are offered to an operator. Thus the load of the operator is reduced.

Abstract: PURPOSE:To exactly measure the useless injection time of the water injection valve, and to improve the control accuracy of the coiling temperature, by installing the detector in the water injection apparatus in order to detect the flow of cooling water injected from the nozzle, in the controller for the hot strip coiling temperature, etc. CONSTITUTION:The water injection detector 43 is installed between the header 41 of the water injection apparatus for cooling the strip and the table roller 42; hereupon, a saucer 31 is arranged so as to be struck by the cooling water injected from the nozzle 22. The detector 43 is arranged so as to put ON the limit switch 32 at a specified water rate to be set by adjusting the pressure regulating spring 33. When the coiling temperature controller 44 produces the command ''ON'' to the water injection valve 14, the time from this command ''ON'' to the limit switch 32 ''ON'' becomes the useless ''ON'' time of the water injection valve 14.
