Title: Apparatua and method for processing of data provided with write-request interlock
Inventor: SAIMON CHIYAARUZU WATSUTO
IPC: G06F5/06
Filed: 1995-03-23
Abstract: PURPOSE: To solve a problem of a failure in both of two write requests in the case that the two write requests try access seeking to a bus simultaneously. CONSTITUTION: A CPU core 4 can be operated by either of an internal clock frequency fc1k and an external clock frequency mc1k. In the case of the operation by the internal clock frequency fc1k, a write request signal is not buffered. In order to avoid it that write request signals reach a signal bus 6 in a disordered sequence, an interlock is provided between two paths so as to hold off an optional write request signal outputted via other path resulting from an optional holding write request signal in the write buffer 10. When the write request signal generated by the external clock frequency is blocked, the CPU core 54 is stopped.

Title: Fixing temperature control method of recording apparatus
Inventor: UGAI TAKESHI
IPC: H05B3/00
Filed: 1979-05-26
Abstract: PURPOSE: To reduce the fluctuation width of fixing temperature in electrostatic recording apparatus, by applying the electric power to compensate for drop of fixing temperature due to heat absorption of recording paper, to a heating element at specified time.  
     CONSTITUTION: The fixing temperature is detected by a temperature sensor 21 provided in the fixing part. In order that the detected fixing temperature may be within the range of specified upper and lower limits, the heating electric power to a heating element 18 is controlled by feedback. Suppose the delay time from application of electric power to the heating element 18 till resultant appearance of fixing temperature rise is t d , then the electric power to compensate for fixing temperature drop due to heat absorption of the recording paper is supplied to the heating element 18 about time t d  before the recording paper reaches the fixing part. Thus, the temperature drop due to heat absorption of the recording paper may be compensated at adequate timing, so that the fluctuation width of fixing temperature may be reduced.

Title: Peak position detecting method for magnetic reproducing device
Inventor: MAEDA YUTAKA
IPC: G11B21/10
Filed: 1988-03-22
Abstract: PURPOSE:To reduce the detecting time of the title method by limiting the searching extent for detecting the peak position of the envelope of a rotating magnetic recording medium to prescribed areas before and after the absolute track position of each track and, at the same time, setting the absolute track position as the peak position when no envelope is detected in the prescribed areas. CONSTITUTION:The peak position detecting process of this method is performed on the track which is discriminated as a recorded track in the course of a track searching process. A magnetic head is first positioned to the absolute track position of the said track and the peak position detecting process is performed with the absolute track position at the center. The process is performed by comparing the level of envelope signals. Since the process cannot be performed at the time of saturation, the gain of a circuit 83 is lowered for performing level comparison. When the peak of an envelope level is found, the position is set as the peak position. When no peak is found, the last feeding position is forcibly set as the peak position.

Title: Method and equipment for inspecting flaw of product
Inventor: YOKOI AKIHIKO
IPC: G06T1/00
Filed: 1993-03-03
Abstract: PURPOSE:To allow easy and accurate high speed detection even of a significant flaw present in the protrusion or recess of a product having a rough irregular pattern using a simple image processing method. CONSTITUTION:With regard to an original image data, a maximum gray level is determined for every rough decision pixel region M of predetermined number of pixels in row and column (S21). Shade is then contracted by substitution for the maximum gray level (S22) and the difference of gray level between an image data and the original image data is calculated for each pixel (S24). With regard to the image data subjected to difference processing, an intermediate gray level is determined for each fine decision pixel region N of predetermined number of pixels in row and column smaller than that in the rough decision pixel region M(S25). Smoothing is then performed by substitution for the intermediate gray level (S26) and each smoothed image data is binarized thus deciding presence or absence of flaw for each pixel.
