Patent EP-0706224-A2 (EP)
Inventor: ONO TAKASHI
IPC: H01L29/792
Filed: 1993-10-05
Abstract: The present invention provides a method of writing data into and erasing it from a semiconductor nonvolatile memory having two diffusion layers (19, 20) formed in a semiconductor substrate (11), a floating gate (13) formed on a layer between the two diffusion layers, a control gate (15) and a select gate (18) formed on a side portion of the control. The method is achieved by applying a potential enabling a channel to be formed between the two diffusion layers (19, 20) to the control gate (15), applying a potential preventing the channel from being formed therebetween to the select gate (18), injecting an electric charge into the floating gate (13) without causing current to flow between the diffusion layers and writing data into the semiconductor nonvolatile memory. Using this method, the memory can be operated with low energy and the number of times in which the data is reloaded or rewritten can be made greater.

Abstract: An image to be read is divided into blocks (0,0..K-1, L-1..K, L) and pixels included in each block are consecutively binarized on the basis of a threshold. At this time, the threshold is determined in accordance with a maximum value of an image signal of an area including a block (K-1, L-1; K, L-1; K-1, L) adjacent to an attention-focused pixel (K, L). If the threshold is smaller than a reference threshold which is determined in accordance with the maximum value of the image signal of a particular reference pixel of a preceding block, the area is changed, and the threshold is redetermined in accordance with the maximum value of the image signal of the new area.

Abstract: A plasma processing apparatus generates high density plasma in a vacuum vessel housing (101) utilizing an electron cyclotron resonance phenomenon caused by an electromagnetic wave in an ultra-high frequency band and a magnetic field. An electromagnetic wave in an ultra-high frequency band for generating plasma is radiated from a planar conductive plate (105, 106, 107, 115, 117) consisting of graphite or silicon which is arranged opposite to the surface of the processed sample (110) into space inside the vacuum vessel (101). High density plasma in the low degree of dissociation can be generated by using an electromagnetic wave in an ultra-high-frequency band and as a result, the controllability of etching reaction can be enhanced. Further, a radical effective in etching can be increased by reaction between the surface of a planar conductive plate for radiating an electromagnetic wave and plasma.

Abstract: The signal converting apparatus and method predictively produces highly accurate interpolated pixels in accordance with a classification which precisely reflects a variety of signal characteristics of inputted video signals to provide a high resolution video signal. An activity is evaluated and classified (12) for each block of an inputted video signal (S1). Stepwise classifications (p0-p2), (Fig 5, 22-24) are executed on each block of the inputted video signal (S1) and a classification (C1) is selected in accordance with an activity code (c0) obtained as a result of the activity classification (21). In this way, the accuracy of subsequent classifications can be increased, reflecting the activity characteristic of each block of the inputted video signal (S1), thus achieving, as a whole, a highly accurate classification of the inputted video signal (S1). Appropriate prediction coefficients (d1) stored in a ROM (14) are read out based on the activity code (c0) and the class code (c1) for each block of the inputted video signal (S1). The coefficients are used in calculators (13) to produce highly accurate interpolated pixel values (d2-d5) which are selected by a selector 15 to provide a high resolution video signal (S2).

Abstract: In a system in which processing modules are coupled to each other and to peripheral devices through a network and wherein the operation of the peripheral device is managed by processing module managers employing different management protocols, the peripheral device includes plural agents each with a different management protocol to exchange data with the managers having the same management protocol. The plural agents are coupled to the managed device by an instrumentation interface which operates to translate request messages from the manager into calling signals for the managed device controller, to receive status and attribute signals from the managed device controller and to send data messages on the status and attribute signals to the requesting agent having the same management protocol as the requesting processing module manager. Alert signals from the managed device are sent to the instrumentation interface which provides data messages on the alert to the plural agents so that the processing module managers having different management protocols can interpret the alert condition of the managed device.
