Title: Demodulator
Inventor: MORIMOTO YOSHINORI
IPC: H04L27/227
Filed: 1991-08-28
Abstract: PURPOSE:To demodulate a QPSK modulation wave accurately and stably by employing a 2fc VCO, a 1/2 frequency divider and a -pi/2 phase shifter for the demodulator. CONSTITUTION:A QPSK modulation wave (carrier frequency is fc) is inputted to the demodulator, in which the wave is processed by a BPF 12 and an AGC amplifier 14. A multiplier 16a multiplies the processed QPSK modulation wave with a 1st carrier being an output of a 1/2 frequency divider 8 to obtain an in-phase detection output I. A multiplier 16b multiplies the processed QPSK modulation wave with a 2nd carrier being an output of a -pi/2 phase shifter 20 to obtain a 90 deg. phase detection output Q. The output of the multiplier 16a is inputted to multipliers 26a, 30b via an LPF and a limiter. The output of the multiplier 16b is inputted to multipliers 26b, 30a, via an LPF and a limiter. The phase difference between the detected outputs I, Q is detected by the multipliers 30a, 30b and an adder 32 to control a VCO 22 via an LPF 34. On the other hand, the output of the multipliers 26a, 26b is given to an AGC amplifier 14 via an adder 36 and an LPF 40 to control the gain.

Abstract: PURPOSE:To detect misreleasing such as double releasing at a high speed and to improve debugging efficiency by turning off a flag provided corresponding to a memory block on confirming the ON state of the flag, and turning on the flag on detecting the OFF state of the flag. CONSTITUTION:This system is provided with a flag-ON detection routine which is executed at the time of hunt routine execution to confirm the ON state of the release flag of an area and a flag-OFF detection routine which is executed in free routine execution to confirm the OFF state of the release flag of the area; and the area is secured on confirming the ON state of a flag showing the releasing of a transaction in the hunt routine execution, and released after the OFF state of the flag is confirmed at the time of releasing. When the area is thus secured, the flag is turned off after the confirmation of the ON state and when the area is released, the OFF state is confirmed to turn on the flag, so even if various routines try to release the same transaction owing to a bug, that is detected from the flag which is released once by the flag-OFF detection routine to prevent the double releasing.

Title: Method for controlling flatness of sheet stock
Inventor: SATO TOSHIYA
IPC: B21B37/00
Filed: 1984-10-17
Abstract: PURPOSE:To maintain well the flatness of a sheet stock by measuring the sheet- thickness distribution in the sheet width direction at the inlet side of rolling rolls and changing a roll profile so that the measured distribution conforms with the sheet- thickness distribution in the same direction at the outlet side of said rolls obtained by a specific equation. CONSTITUTION:After rolling a sheet stock S by the 4th stand, the sheet thickness distribution in the sheet width direction of stock S is measured by a gamma-ray thickness meter 53 of sheet-width direction moving type, and its signal is inputted to an arithmetic unit 6. The unit 6 operates the sheet thickness distribution g(x) of stock S, obtained after rolling by the 5th stand, based on said signal and an equation, to generate a signal used for controlling the roll profile of a work roll 51. A roll bending device 54 changes the roll profile of roll 15 so as to conform the sheet-thickness distribution with the g(x) of equation by inputting the signal of unit 6. In this equation, each factor is denoted by the following sign, where; f(x): sheet thickness distribution in sheet width direction at inlet side of rolling roll, HCS: thickness of central part in sheet width direction at inlet side of rolling roll, (h): thickness of central part in sheet width direction at outlet side of rolling roll. Further, the profiles of work rolls 61, 71 are also controlled at the 6, 7th stands in the same manner as the control at 5th stand.

Title: Image forming device
Inventor: KITAZAWA ATSUNORI
IPC: G03G21/10
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To hardly turn up a cleaning blade even in the case of increasing the contact pressure and/or contact angle of the cleaning blade by always heaping the toner scraped by the cleaning blade at the contact part of the cleaning blade with an image carrier and a part just below the contact part. SOLUTION: The toner T remaining on the image carrier after the toner image on the image carrier is transferred is scraped and removed by the cleaning blade 21 in contact with the surface of the image carrier 10. Then, the toner T scraped by the blade 21 is always heaped at the contact part C of the blade 21 with the image carrier 10 and the part U just below the contact part C. Therefore, the toner T is always supplied to the contact part of the blade 21 with the rotating image carrier 10 without being affected by an image pattern. Since the toner T has a function as lubricant, frictional force between the blade 21 and the surface of the photoreceptor gets low and the blade 21 is hardly turned up.
