Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To attain high quality information transmission by obtaining desired error correction capability without increasing redundant data for error correction so as to maintain the transmission efficiency. SOLUTION: A transmitter on the receiver side converts a received base band signal sent from a transmitter on the transmission side through multi- carrier into a parallel signal vi(i=0, 1,..., 7) and given to a discrete Fourier transform device 25, in which the signal is converted into a signal Vk (k=0, 1,..., 7) on a frequency and it is given to an error correction decoder 26. Then four null signals X0, X1, X6, X7 are known between the transmitter and the receiver to estimate received information data X2, X3, X4, X5 from the received block signal Vk(k=0, 1,..., 7).

Title: Paper detecting device for sorter discharge tray
Inventor: KATSUMATA TSUTOMU
IPC: G03G15/00
Filed: 1990-07-13
Abstract: PURPOSE:To surely prevent paper jam by allowing a paper sensor to detect that the loadage of papers exceeds the limit for terminating discharge papers, prohibiting copy and driving an alarm system as necessary. CONSTITUTION:A paper sensor 18, which has a light emitter 16 and a light receiver 17 faced to each other at an inclination alpha of 2-3 deg. to the level surface of a discharge tray 12, provides reliable detection of a paper 14, including the plane portion on the upper side, at a consistent position. When the paper 14 is copied and discharged, the sensor 18 detects condition how it is discharged in. If it takes less 5 seconds to finish operation from paper discharge to paper placing on the discharge tray 12, the discharge tray 12 is moved upward (or downward) and shifted for the acceptance of the next discharge paper. If the operation is still continued after 5 seconds or more passed, such a measure is taken as the movement to the next tray 12 for loading, the drive of an alarm for full-load situation, or no start of a copying machine 11.
Patent JP-H1031364-A (JP)
Title: Developing device
Inventor: SANADA YOSHIAKI
IPC: G03G15/09
Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To perfectly recover developer in a developing tank without scattering the developer by making the intensity of magnetic field in the tangential direction of the surface of a sleeve opposed to the downstream end of the opening of the developing tank lower than that on the upstream side and the downstream side of the surface of the sleeve. SOLUTION: The intensity of magnetic field in the tangential direction at the most proximate position on the surface of the sleeve 14 is set to be lower than the intensity of the magnetic field on the upstream side. Thus, the magnetic field acts on the developer in a direction shown by an arrow. On the downstream side of an opening 23, the thickness of the napping of the developer in a radial direction on the surface of the sleeve 14 near the most proximate position of the sleeve 14 becomes smaller than that before and behind the position, and impact force by the developer is reduced. Then, the intensity of the magnetic field in the tangential direction thereat is set lower then the intensity of the magnetic field on the downstream side. Thus, carrying force is increased by a carrying magnetic pole B even after the developer is carried in the developing tank 16.  Therefore, a situation that the developer is retained in the developing tank 16 near the most proximate position and the pressure of the developer is increased is prevented and the back flow of air from the aperture 23 is prevented.

Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To protect a semiconductor device against latch-up even if access is much sped up and electric powers are successively applied in any sequence. SOLUTION: When a chip inner voltage VDD is applied first, an N well bias circuit 9 and a P well bias circuit 10 are actuated, and an N well 12 and a P well 13 are biased.

Filed: 1990-07-13
Abstract: PURPOSE:To enable fiber to be prevented from its discoloring and fading by subjecting air in a storage space for fiber, etc., to oxidation treatment and then absorption treatment and removing nitrogen dioxide contained in the aforementioned air. CONSTITUTION:Air is sucked and passed through an oxidation bottle containing a potassium permanganate solution acidic with sulfuric acid in a storage space for fiber such as a storehouse to oxidize nitrogen monoxide in the air into nitrogen dioxide. The resultant air is then passed through an absorbing solution composed of a mixed solution of naphthylethylenediamine dihydrochloride, sulfamic acid and glacial acetic acid to remove the nitrogen dioxide caused by exhaust gases from heating equipment or automobiles contained in the air. Thereby, the obtained air is subsequently fed to the aforementioned storage space.

Abstract: PURPOSE:To make semipermanent continuance of kinetic energy attainable, by making centrifugal force use the form of a flywheel to function as internal force to the flywheel and simultaneously forming it functionable as external force which rotates and drives the flywheel in the same direction as its rotating direction. CONSTITUTION:Even when a flywheel D rotates and moves in any position on an orbital circle 8 centering on a center point 14, all these forms are rotation symmetrical form with one another centering on the center point 14, and the flywheel D always naturally generates turning force 2 or centrifugal force and external force to rotate the flywheel D in the same direction as its rotating direction, namely, turning force 22 for a while it conducts its rotational motion in the said rotating direction. With this constitution, reaction 37 is offset to turning force 10 while reaction 15 to turning force 30, respectively, thus since external force will not work on the flywheel D all, the flywheel D theoretically comes possible to do perpetual uniform, rotational motion even if there is not external force, namely, no fuel.

Title: Detection method of cutting depth and device therefor
Inventor: OKUMA TAKAMASA
IPC: B23Q15/14
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To cut while detecting simply and accurately as the distance between the conductor of the inside of a work and a cutting tool is born to a practical use by flowing a high frequency current between the cutting tool of a machine tool and the conductor of the inside of the work. SOLUTION: When a cutting tool 3 is contacted to the upper surface of a work 11, the electrode of C5 is connected by a conductor. Thereafter, as the electrode gap of C4 becomes smaller when the cutting tool 3 approaches to the conductor 13 of the metal inside the work 11, the high frequency current begins to flow too much. When the cutting tool 3 is contacted to the conductor 13 of the metal inside the work 11, the electrode of C4 is connected by the conductor and the high frequency current becomes maximum. When a signal output device 34 is set so as to output a signal to the control device of a machine tool so as to stop the cutting, the cutting is stopped.
