40results about How to "Efficient erase" patented technology

Non-volatile memory devices and arrays are described that facilitate the use of band-gap engineered gate stacks with asymmetric tunnel barriers in floating gate memory cells in NOR or NAND memory architectures that allow for direct tunneling programming and erase with electrons and holes, while maintaining high charge blocking barriers and deep carrier trapping sites for good charge retention. The direct tunneling program and erase capability reduces damage to the gate stack and the crystal lattice from high energy carriers, reducing write fatigue and leakage issues and enhancing device lifespan. Memory cells of the present invention also allow multiple bit storage in a single memory cell, and allow for programming and erase with reduced voltages. A positive voltage erase process via hole tunneling is also provided.

A free page extracting unit extracts a free page of a non-volatile memory. A directory page writing unit writes, to the free page extracted by the free page extracting unit, a directory that includes a logical page/physical page translation table of a page to which updated data are to be written. Further, a data page writing unit writes updated data to the free page extracted by the free page extracting unit. Therefore, even when data updating operation is interrupted, loss of the original data can be prevented, and the data before updating can be recovered.

In order to protect audio signals against copying, it is proposed to mix the audio signal with at least one non-audible disturbance signal. A first disturbance signal may be a low-frequency signal which is added to the audio signal, while a second disturbance signal may be a high-frequency disturbance signal which is multiplied with the audio signal. Additionally, the second disturbance signal may be modulated by a modulating signal comprising either the original or inverted original signal, or spoken messages indicative of an illegal copy.

A video display method is used in a display device that displays images in correspondence with frames or fields defined by a video signal on the basis of the video signal. The video display method includes a step of generating mask patterns in correspondence with frames or fields defined by the video signal such that the mask patterns corresponding to consecutive frames or fields defined by the video signal are different from each other. The mask patterns include randomly arranged black and white dots or patterns. At least one of the images is displayed on the basis of the video signal and then at least one of the generated mask patterns is displayed.

Receiving a request for canceling setting, a control circuit erases data stored in a corresponding block, changes a value of a protection flag, and cancels protection setting. When an overall protection is set for any block, the control circuit prohibits access to all blocks, except when it is an operation mode for activating a memory program contained in the microcomputer. Further, control circuit permits an access to a block M only when partial protection is set, CPU is in the mode for activating a memory program contained in the microcomputer and the access is for reading an instruction code in accordance with an instruction fetch.

The invention relates to a crawler type water removal device used for a tire rubber assembly. The crawler type water removal device comprises a rack, an upper head supporting roller, an upper tail supporting roller, a lower head supporting roller, a lower tail supporting roller, an inner turning roller, an outer turning roller, a water extrusion roller, a drive device and a crawler sponge; the upper supporting rollers, the inner turning roller, the lower supporting rollers and the outer turning roller are sequentially sleeved with the crawler sponge, and the moving direction of the crawler sponge is perpendicular to the moving direction of the tire rubber assembly; the device makes friction with the upper surface and the lower surface of the tire rubber assembly through the crawler sponge, meanwhile, water on the upper surface and the lower surface of the tire rubber assembly can be dried, energy is saved, and the environment-friendly effect is achieved; a cord layer can prolong the service life of the crawler sponge, and on the premise of protecting the crawler sponge against damage, the rubber assembly can smoothly penetrate the crawler sponge.

In a solid state radiation detector which includes an electrostatic recording section having a photoconductive layer that shows conductivity when exposed to recording light, and is constructed to receive recording light representing image information to record the image information in the detector, and to output image signals representing the recorded image information, the photoconductive layer is swept by an amount of major carrier greater than or equal to an amount of current that flows through the photoconductive layer at the time of recording to facilitate the recombination of minor carriers (residual charges) accumulated in the photoconductive layer.

In an image forming device including hardware resources for image-formation processing and a program for executing an image-formation-related process, a mode judgment unit determines whether the image forming device is to be started in a clearing mode or a normal starting mode, the clearing mode being configured to erase, when the image forming device is started, data stored in a storage device of the image forming device. A process starting unit starts execution of the image-formation-related process in response to both a result of the determination of the mode judgment unit and an image-forming-device setup data. A data erasing unit erases the data stored in the storage device when the image forming device is started in the clearing mode.

The invention relates to a double wringing water removal method for a tire rubber component. The double wringing water removal method comprises the steps of front traction, device reversal, feeding, reversal stop, rear traction, transmission beginning, device water removal and water removal completion. The method can reduce damage to a crawler shaped sponge during mounting of the rubber component and prolongs the service life of a device; a driving device reverses to allow the tire rubber component to pass through a double wringing water removal device; hands are prevented from stretching into the double wringing water removal device; industrial accidents are reduced; an upper and lower surface friction and contact mode of the two crawler shaped sponges and the tire rubber component is adopted; the upper and lower sponges are subjected to wringing treatment; continuous water absorption efficiency of the sponge is ensured; and water on the surface of the rubber component can be wiped efficiently and cleanly.

The invention relates to a device for reversely erasing a viscous fluid substance on surface of a soft roller by a hard roller and belongs to the technical field of a printing machine. The device comprises a doctor blade which has an upward cutter point and comprises a protraction position and a retreating position; the cutter point of the doctor blade is contacted with a metal reversely erasing roller line when the doctor blade is at the protraction position; an ink receiving device is arranged below the doctor blade; the metal reversely erasing roller is tangent with a plate erasing roller and rotates reversely; firstly, the viscous fluid substances such as waste ink and the like are erased from the surface of the plate erasing roller through the metal reversely erasing roller in working, and the waste ink on the metal reversely erasing roller is transferred and removed by the doctor blade and gradually flows to the ink receiving device under the action of gravity, so that erasing effect of the ink can be ensured by reverse contact rotation of the metal reversely erasing roller and the plate erasing roller; the doctor blade is not directly contacted with the plate erasing roller, so that injury cannot be generated; and the waste ink is automatically gathered, so that severe contamination cannot be generated.
