Title: Information signal recording and reproducing system
Inventor: MASHITA TSUGUAKI
IPC: G11B20/08
Filed: 1988-11-08
Abstract: PURPOSE:To record and reproduce an information signal in a wide band by recording and reproducing 1st and 2nd dividing signals respectively obtained at the fall and the rise of a PWM(pulse width modulation) signal and performing the exclusive OR operation of 1st and 2nd reproduced dividing signals which are reproduced so that a reproduced PWM signal may be obtained. CONSTITUTION:A 1/2 frequency divider 13 obtains the 1st dividing signal triggered at the fall of the PWM signal which is obtained by modulating the pulse width of the information signal so that the PWM signal is 1/2 divided and a 1/2 frequency divider 14 obtains the 2nd dividing signal triggered at the rise of the PWM signal so that the PWM signal is 1/2 divided. Both dividing signals are recorded in a recording medium 19 together. A synthesis circuit 22 performs the exclusive OR operation of the 1st and the 2nd reproduced dividing signals reproduced from the recording medium 19 to obtain the reproduced PWM signal and the information signal is obtained by demodulating the pulse width of the reproduced PWM signal. Thus, the pulse width of each pulse of the PWM signal is accurately restored even if the variation of a recording and reproducing state such as the variation of a beam spot, etc., occurs and recording and reproducing the information signal in the wide band is accomplished.

Then the contents of conversion and the length of a sentence are registered and stored in a conversion information control part 3. Then the registration contents of the part 3 referred to and edited by the part 5 in response to the input. Thus a KANJI- KANA sentence converted into its original sentence is outputted from an output control part 4 easily and completely and displayed with no operation of the homonym selection key and the non-conversion key.

Title: Controlling method for image forming device
Inventor: SENBA HISAAKI
IPC: G03G15/02
Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To attain uniform electrification by AC component while an AC current to be applied is controlled low and the shaving quantity of a body to be electrified is reduced by detecting voltage/current characteristics corresponding to capacitance for the thickness of the body to be electrified. SOLUTION: Specified AC voltage and DC voltage for detection are applied to an electrifying roller 2 in a non-image-forming area. Although a difference between positive component and negative component out of a current then, namely, DC component quantity is equivalent to the current so as to finally impart surface potential to a photoreceptor 1, DC current quantity for obtaining the same surface potential in accordance with the change of the film thickness of the photoreceptor 1 is changed. Thus, the capacitance is increased as the film thickness of the photoreceptor 1 is thinned, so that the DC component quantity I is increased. It shows, on the contrary, that the film thickness is predicted by detecting the quantity IDC. Then, the current is detected. A constant current value applied at an image forming area in accordance with a current value is decided by a second quadrant line.  Thus, DC component is detected, and image-forming is performed by the constant current value corresponding to its value.

Abstract: PURPOSE:To bring a powder material to compact powder forming without damaging a green compact by dividing and constituting a second punch being longer than a first punch in a powder forming punch of a material whose Young's modulus is higher than that of a first punch for a part thereof. CONSTITUTION:In a powder forming punch, a first vertically long cylindrical punch 5 is attached onto a first punch holder 8, and also, on a core rod 3, a second punch holder 7 for passing through the rod is provided so that it can ascend and descend freely, and a second cylindrical punch 4 internally contacted with the core rod 3 is attached thereon. In this case, the upper half 4a of the second punch 4 is formed of alloy steel of the same quality of the first punch 5, and the lower half 4b thereof is formed of a cemented carbide whose Young's modulus is high. Since a material whose Young's modulus is high is used partially for the second punch, when pressurizing force works by the upper punch 11, the contraction quantum by a compressive stress of the second punch 4 being longer than the first punch 5 is decreased and can be matched with the contraction quantum of the first punch, and a green com pact is formed without being damaged.
