Abstract: PROBLEM TO BE SOLVED: To obtain a flash memory device in which the load of a negative charge pump is minimized and which prevents a drop in the operating characteristic of an element by a method wherein a memory cell block is selected by an erase signal and the output voltage of the negative charge pump is supplied. SOLUTION: When an erase signal at a high level is input to a block selection signal 2 so as to output a first high-level output signal B1, the output voltage of a negative charge pump 1 is dropped so as to be applied to an output terminal R at a first local pump circuit P1, a first switching means Q1 is operated, the output voltage of the pump 1 is supplied to a first memory cell block MB1, and an erase operation is performed. When the erase operation of the block MB1 is completed, an erase completion signal is input to a clock generation circuit 3, a clock signal CLK is output, a second output signal B2 to be output from a circuit 2 is set to a high level, and the erase operation of a block MB2 is completed in the same manner as the block MB1. This operation is performed up to a signal B4.  When the erase operation of a block MB3 and that of a block MB4 are completed, a block erase completion signal and the signal B4 are input to a generator 3, and an erase finish signal is output. Thereby, the load of the pump 1 can be minimized.

Title: Character processor
Inventor: SAKAKIBARA ATSUSHI
IPC: G06F17/24
Filed: 1989-10-20
Abstract: PURPOSE:To effectively use a memory space by extracting a character string that satisfies the conditions to be pointed out and its substitute candidate character strings among those documents stored in a document storage means and using these extracted character strings. CONSTITUTION:A character string satisfying the conditions to be pointed out and its substitute candidate character strings are extracted among the documents. The character string satisfying the conditions to be pointed out is detected among the documents stored in a document storage means. This detected character string is stored and displayed together with its position in the document and its satisfied conditions as well as its substitute candidate strings. Thus, it is not required to register such character strings not included in the documents and to be corrected and their substitute candidate strings into a dictionary. Then the least necessary number of memories are used with high efficiency. Furthermore it is possible to prevent such a case where the character strings to be corrected and stored in the documents are not pointed since they are not registered yet in the dictionary.

Title: Electron microscope with neutral particle beam radiating device
Inventor: HONDA TOSHIKAZU
IPC: H01J37/26
Filed: 1985-12-06
Abstract: PURPOSE:To realize an optimum design and improve the resolution without resticting the form of a pole piece for an object lens, by forming a gaseous layer on the electron beam optical axis, and radiating the electron beams to the gaseous layer. CONSTITUTION:On the way that electron beams 3 pass through an intermediate chamber 8, the electron beams strike to the accumulated gas molecules g in the intermediate chamber 8, giving the speed V1 in the direction of the electron beam passing to the gas molecules g. When the initial speed of the gas molecules g is V0, the given speed V=V0+V1. Furthermore, since the electrons which passed through a differential exhaust throttle 7 and the gas molecules repeat striking again and again to accelerate the speed of the gas molecules g, almost all the gas molecules g are converted into neutral particle beams 3' and radiated over the sample 5. The neutral particles radiated over the sample strike to the sample with a kinetic energy mv<2>. Since such neutral particles are not charged, they flow straightly without deflection in the magnetic field of the object lens, and irradiate the analysis point, or the electron beam radiating point accurately. Therefore, the gas and impurities attached over the sample 5 are removed, and a clean sample can be observed.

Title: Nucleic acid probe and method for detecting fungus
Inventor: UIRIAMU JII UEISUBAAGU
IPC: C12Q1/68
Filed: 1990-10-12
Abstract: Nucleic acid probes are described for detecting fungi capable of causing fungal septicemia or capable of causing food spoilage. The preferred probes are complementary to ribonucleic acid sequences found in numerous fungi and absent in animal or plant genomes. As such, these probes can detect the rBNA, rDNA, or polymerase chain reaction amplification products from the majority of fungal species. The detection of etiological agents of human fungemia, the clinical diagnosis of this disease and the direct evaluation of food or beverage fungal content utilizing rRNA or rDNA probes is now possible.

Title: System for detecting number of sheets of wafer
Inventor: KOSUGI TETSUYA
IPC: H01L21/67
Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To detect disconnection if a connection line between an optical element and a control part is disconnected and prevent transfer of a double wafer, by a method wherein a wafer detection is falsely made in a state that the wafer is not between the optical elements. SOLUTION: A wafer sensor is stopped at a set position for detecting the number of sheets of wafer. Set as a state of detecting the number of sheets of wafer, a light omission of a light emission part E is stopped, and 'presence of wafer' is falsely set for all light receiving parts D of a port set as a state of detecting the number of sheets of wafer. Then, if a system for detecting the number of sheets of wafer is normal, an output DT is set 'H' according to a potential of a position D1, and a control part detects 'presence of wafer'. While, when a connection line is disconnected, if a light projection of a light projection part E is stopped, the output DT is still 'L'. Therefore, the control part detects 'no wafer'. For this reason, if the light receiving part D is abnormal, an automatic detection is possible, and a problem such as a double wafer transfer, etc., can be prevented.

IPC: E21D11/10
Filed: 1994-10-15
Abstract: PURPOSE: To keep cracks from forming and to enhance a waterproofing effect by sandwiching a mixture layer consisting of a cement crystallization enhancer and a buffer material between the shotcrete of primary lining and the concrete of secondary lining. CONSTITUTION: After a tunnel is excavated, primary lining is constructed on its interior wall by shotcrete 3, and lock bolts 2 are driven into the natural ground 1. After the shotcrete 3 sets, a mixture of a cement crystallization enhancer 4, a buffer material 5 and water is sprayed onto the surface of the shotcrete 3 by a thickness of several mm to 1cm to form a mixture layer. After the mixture layer sets, concrete 6 is poured onto the layer to construct secondary lining. The cement crystallization enhancer 4 penetrates and diffuses into capillaries, cavities and cracks, increasing the crystals of the cement and enhancing a waterproofing effect. Also, the mixture layer is deformed with setting contraction and with changes in the earth-pressure stress of the natural ground 1 to disperse and absorb the stress.

Title: Power semiconductor device
Inventor: KOIKE YOSHIHIKO
IPC: H01L25/07
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To reduce the inductance of a module by mounting even number of semiconductor elements on an insulation substrate, providing a circuit unit for parallel operation of even number of insulation substrates, and disposing module outer terminals corresponding to the circuit unit to thereby operate in parallel from outside the module. SOLUTION: Even no. of semiconductor elements 101, 102 are mounted on each of DBC-AlN substrates 103. An IGBT unit to be operated in parallel through terminal wirings in the module is composed of even number of DBC-AlN substrates 103. The IGBT units are wired in the module and operated in parallel. This structure ensures that even a large-capacity module with many semiconductor elements is operative with keeping these elements balanced enough to be switched at high speed and enhances the short-circuit resistance. This also reduces the inductance of the module and makes uniform the solder reliability for connecting the terminals to the insulation substrates even in a large-capacity and large-size module.
