Title: Ghost elimination device
Inventor: ISHII AKIRA
IPC: H04N5/21
Filed: 1991-05-31
Abstract: PURPOSE:To extend the ghost elimination range by using an elimination signal obtained through calculation so as to eliminate a waveform around a tail end ridge of a reference signal thereby obtaining only a waveform distortion at a front ridge of the reference signal. CONSTITUTION:An input video signal is digitized by an A/D converter 12 and the result is inputted to a transversal filter TF 14 and a delay device 13, the outputs are subtracted at a subtractor 15, the result and an output signal of a TF 17 are subtracted by a subtractor 16 and the result is outputted to an output waveform memory 22. A ghost elimination reference signal GCR inserted to a digital video signal before and after ghost elimination is stored respectively to input and output waveform memories 21, 22. An MPU 25 obtains a difference of the GCR signals in the memories 21, 22, detects a maximum peak to obtain a peak position and obtains a frequency characteristic and a waveform distortion characteristic at the tail ridge of GCR and sums them. Thus, the waveform from which ghost is eliminated is obtained. Thus, an error component is detected and the correction of the tap coefficient of the TFs 14, 17 is implemented to correct the tap coefficient based on the error component and the GCR signal.

Title: Program monitoring device and device to be driven by program
Inventor: KONISHI ISAO
IPC: G06F11/30
Filed: 1995-05-29
Abstract: PURPOSE: To easily detect the runaway, etc., of a program in a short time by stopping measurement when any change is detected between a video signal stored for each period of a synchronizing signal from an image display device and the video signal of the next period. CONSTITUTION: A measuring means 15B measures time by counting the number of synchronizing signals from the device, which is driven by the program and displays an image on the display device, and the video signal is stored in a storage means 15D for each period of this synchronizing signal. Then, a comparing means 15E compares the video signal stored in the storage means 15D with the video signal of the next period and when its signal change is detected, a signal change detecting means 15C stops the measurement of the measuring means 15B. In this case, when the video signal is changed from a different repeat signal pattern to a fixed signal pattern at the signal change detecting means 15C or changed from the fixed signal pattern to the different repeat signal pattern, the measuring means 15B measures its time.

Title: Program correcting method
Inventor: SATO YOSHIO
IPC: G06F11/28
Filed: 1988-05-30
Abstract: PURPOSE:To omit the exchange of a fixed memory storing a program by storing a return instruction into the end of a corrected program to ensure a return to an address following a corrected part of the fixed memory. CONSTITUTION:A program of a ROM 1 is carried out by a CPU between a jump instruction JMP-R2 of an address A1 and an instruction JMP-R3 of an address A3. Then a corrected program AP3' following an address R3' is carried out based on an instruction JMP-R3' of a nonvolatile memory UDM2. Then the execution is shifted to an address (A4+1) of the ROM 1 in response to the final return instruction RETURN-(A4+1) and a program AP4 is carried out. Thus a program AP3 is replaced with the program AP3' and the contents of the AP3' can be corrected with no exchange of the ROM 1.

Abstract: PURPOSE:To obtain an inclined type continuous mixer applicable for mixing materials having a remarkable difference of specific gravity among each containing material, by using a mixer in which spiral blades are provided discontinuously of which a rotating range over-laps partly each other. CONSTITUTION:Supporting arms 2 are attached vertically to a shaft 3 provided at a mixer main body 1 having an inclined angle; spiral blades 4, rotating adjacently to the inner wall of the main body 1, are attached to the arms 2 at the position where each blade 4 is attached not to be continuously connected each other by rotating it in the circumferential direction of the shaft 3 and a part of its rotating range to be overlapped each other. Therefore materials fed from a charging port 5 are moved downward by their self weights along the inclination of the main body, but are moved upward by the blades 4 having the overlapped zones of the rotating ranges, and mixed by repeating said motion. Thus the materials having the difference of the specific gravity among each containing material are mixed uniformly.
