Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To provide an image-forming apparatus which can prevent a productivity decrease by an error return retry process more than required in a large- capacity image storage means such as a hard disk or the like. SOLUTION: A hard disk manages areas in units of a predetermined size, and writes and reads by every predetermined size. When the predetermined size is not occupied with image data, a dummy is written or read out (S1037 and S1039). When an abnormality is detected during the transmission of the dummy, an error return retry is not carried out because the apparatus does not fail in transmitting the image data (S1041, YES).

Title: Method and apparatus for predicting life expectancy of stainless steel material
Inventor: AOYAMA TAKASHI
IPC: G01N23/09
Filed: 1994-06-15
Abstract: PURPOSE:To predict the life expectancy of stainless steel easily and uniquely by measuring the length of crack in a test piece and the intergranular concentration upon elapse of a predetermined interval and then calculating the crack latent time and the lifetime based upon this. CONSTITUTION:A test piece of stainless steel material has known initial intergranular Cr concentration Cr0 at the time t0 of starting to use, and known Cr concentration (corrosion starting critical Cr concentration) Cr1 at a crack latent time t1 when a crack begins to appear. When the intergranular Cr concentration Cr2 is measured by means of a transmission electron analytic microscope and the crack length L2 is measured by means of an optical microscope upon elapse of a predetermined time t2, the latent time t1 can be determined as follows; t1= {(Cr0-Cr1)/(Cr0-Cr2) }Xt2. Subsequently, the lifetime t3 and equal determined as follows; t3=t1+(t2-t1) (L2/L3)<1/2>. (L3 represents the crack length for the lifetime t3 and equal to a crack developing speed (v) integrated from time t1 to t2). Finally, the life expectancy T=t3-t2 of steel material is determined as follows; T=(t1-t2)+(t2--t1)(L2/L3)<1/2>.

Title: Tape speed control method
Inventor: HATSUTORI SHIROU
IPC: G11B15/46
Filed: 1982-07-29
Abstract: PURPOSE:To perform stable control even when the tension of a tape is low or when the tape runs at a high speed, and to prevent a runaway even if the tape is cut, by detecting a tape wind radius detection signal and a radius variation signal, and generating a reference speed signal from both signals and controlling the rotating speed of a reel. CONSTITUTION:A feed reel circuit signal (a) and a run signal (e) are inputted to a tape wind radius detection part 18 once the tape starts running to obtain a signal (h) corresponding to the wind radius at the starting point of the run. The signal (h) enters into a constant state instantaneously and a signal (a) which does not vary is inputted to a tape thickness correction part 19 thereafter to obtain the tape wind radius variation signal (k) which varies stepwise in proportion to variation in wind radius of a wing part 11. An arithmetic part 20 generates the reference tape speed signal (q) from the signal (h) and (k). An F/V converter 22 obtains a current feed reel revolving speed signal (r) from the signal (a). A comparison amplification part 23 outputs a signal 5 which drives a feed reel motor 13 so that the difference of the signal (r) from the signal (q) is eliminated. Therefore, a slip occurs during the run, no influence upon the signal (q) is exerted and the tape speed is not influenced. Even if the tape is cut, no runaway occurs.

Abstract: PURPOSE:To expand the high frequency limit of a treated frequency by amplifying, multiplying a timing signal by N, branching the resulting signal into two, inputting one signal to a logic circuit via a delay circuit and applying OR processing with a timing component extracted coarsely. CONSTITUTION:The output signal of a narrow band amplifier 5 is branched into two and inputted to a limiter amplifier 6 and a broad band amplifier 14.

The f0 clock signal outputted from the circuit 17 is branched into two, one is inputted to a delay circuit 13, where the signal is subjected to a prescribed delay, the resulting is fed to an OR circuit 11. Thus, the f0 clock signal as the output signal from the circuit 11 as the result of ORing the stable f0 clock signal inputted from the circuit 13 coarse f0 component clock signal from the 1st timing extraction filter 18 is outputted. The branched other signal is inputted to an identification circuit 7.

Filed: 1991-05-10
Abstract: PURPOSE:To demodulate an accurate color signal and to secure high horizontal resolution even when a signal level of one color is high in the color signal demodulation circuit. CONSTITUTION:A low frequency detection circuit 13 outputs an attenuation level signal 1/YL in response to a low frequency level of a Y signal to correction signal generating circuits 29, 39, 49, and a high frequency detection circuit 9 outputs a high frequency signal YH in response to the high frequency level of the Y signal.
