摘要： PROBLEM TO BE SOLVED: To conduct analysis/recognition processing for images and audio data or the like, in a real time with high accuracy. SOLUTION: The device is provided with a code book system compression section 102, that seeks code vectors similar to a plurality of vectors extracted from input data from a code book prepared in advance respectively and outputs a code corresponding to them and a frequency distribution generating section 104, that uses an outputted code stream to generate frequency distribution of the output codes. Then an output code stream after conducting matching for the input data is used to generate the frequency distribution so as to analyze the data and the data are recognized, based on a difference from the frequency distribution so as to conduct analysis and recognition processing of the input data, without the need for processing which requires an extremely large calculation, such as frequency transformer processing or the like as typified by Fourier transformation.

摘要： PROBLEM TO BE SOLVED: To realize a rinse water or a chemical by which (1) a surface oxide film is hardly formed, (2) particles are removed or the adhesion of particles is prevented, (3) the hydrogen termination of a silicon atom is promoted, in the chemical cleaning step or the rinsing step using pure water or ultrapure water in the semiconductor wet cleaning process. SOLUTION: In this cleaning method, the forming of a surface oxide film is suppressed by adding hydrogen gas to pure water or ultrapure water used for the rinsing, and, when a silicon substrate is cleaned, hydrogen termination on the surface is promoted. Cleaning is conducted while giving a vibration at a frequency of 500 kHz or more to the pure water or ultrapure water to which hydrogen gas are added in order to remove particles or prevent the readhesion of particles. The effect of preventing the adhesion of particles is produced in addition to the conventional etching effect on the surface by adding ozone or hydrogen peroxide having an oxydizing ability to hydrofluoric acid. By the following step in which cleaning with a rinsing water to which hydrogen gas is added to the pure water or ultrapure water, the termination of hydrogen which is slowed by adding the ozone or the hydrogen peroxide is promoted.

摘要： PROBLEM TO BE SOLVED: To obtain a semiconductor memory device in which analog data and multivalued data can be stored at high speed and with high accuracy by a method wherein, when the output voltage of a readout circuit becomes equal to a prescribed voltage, a write finish signal is output, an analog voltage value and a multivalued voltage value are input to an input terminal and an output voltage which corresponds to the voltage values is output. SOLUTION: The control gate 115 of a memory cell is set at a set voltage. A terminal 111 is set at '1'. When the voltage of the output terminal 104 of a readout circuit and that of an input terminal 105 are not equal, the output of an output terminal 110 is set at '0'. The write voltage of an output terminal 113 is output to the output terminal 101 of a write voltage changeover circuit, and a write operation is started. During the write operation, the voltage value of a floating gate 117 is read out by the readout circuit so as to be output to the terminal 104. When the voltage value of the terminal 104 and that of the terminal 105 become equal at a comparator, '0' is input to the terminal 110 as a write finish signal, and the output voltage of the terminal 101 is changed over to the write finish voltage of a terminal 112.

摘要： PROBLEM TO BE SOLVED: To maintain high plasma density, even if a processing object is diametrically enlarged by directly connecting an electrode to an electric power supply means by a conductor, without arranging a matching circuit constituting a distributed constant line and a matching box between the electrode and the electric power supply means in the matching circuit. SOLUTION: A plasma device is constituted by directly connecting an electrode 107 and an electric power supply means 101 by a conductor 105 to reduce power loss supplied to the electrode from the electric power supply means, except for a matching circuit constituting a distributed constant line and a matching box almost decided in characteristic impedance. The output of the electric power supply means 101 is connected directly to the electrode 107 via the conductor 105 so that a processing object 108 is arranged on the electrode 107. A multistage high frequency amplifier 103 uses an electric circuit constituted of plural bipolar transistors, an inductor, a capacitor and a DC power source, and the matching circuit 104 does not use a semi-fixed variable capacitor but rather uses a variable capacitor.

摘要： PROBLEM TO BE SOLVED: To attain pressure flow control of high accuracy by providing an inlet tapered part, a short throttle parallel part, a short tapered part and a parallel diameter-enlarged part continuously in this order. SOLUTION: An orifice for a pressure type flow control device is composed of an orifice A, an inlet tapered part 1, a throttle parallel part 2, a tapered diameter-enlarged part 3 and a parallel diameter-enlarged part 4. As a concrete example, it is confirmed that linearity between a flow rate and primary pressure P1 is ensured over a range of the flow characteristic P2 /P1 of the orifice (a parallel diameter-enlarged part inner diameter (ϕ2 =0.2 mm) A being P2 /P1 =0.633 (P1 =3.0 kgf/cm abs, P2 =1.89 kgf/cm abs), that is, in spite of a form of the orifice A based on machining of only deburring by an R-cutting tool, a drill and a center drill, the linear characteristic of any orifice A is held to a point of P2 /P1 =0.633 so as to attain flow control of high accuracy.

摘要： PROBLEM TO BE SOLVED: To quickly perform initial fire fighting, protect life of persons in a clean room, and further prevent devices disposed in the clean room from being contaminated to the utmost. SOLUTION: When a fire occurs in a clean room including a clean chamber 30, the supply of air-conditioned air to the interior of a ceiling chamber 18 from an external air conditioner 14 is stopped and only the air circulation of the ceiling chamber 18 and the clean chamber is continued in the state of intercepting a supply path for oxygen. Under the condition of continuing such air circulation, while the air in the clean chamber 30 is discharged, fire fighting gas comprising carbon dioxide and inert gas is emitted into the ceiling chamber 18. The fire fighting gas emitted in the ceiling chamber 18 is jetted into the clean chamber 30 through a HEPA filter 28 disposed in the ceiling surface 26 by air circulation. Thus, oxygen concentration in the clean chamber 30 is quickly lowered so as to perform quick fire fighting.
