Title: Negative ion source
Inventor: YAMAMOTO HIROCHIKA
IPC: H01J37/08
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a high intensity negative ion beam without using an alkali metal such as cesium in a negative ion source. SOLUTION: A negative active gas is introduced from a plasma generating gas inlet pipe 3 to generate a plasma by the thermion emitted from a filament 5. Since the electron emitting part 1 of a sputter target 7 is biased to negative potential, the sputter get 7 is sputtered by the positive ion in the plasma. Since diamond having low electron affinity or negative electron affinity is used for the electron emitting member, electrons are easily emitted when the negative bias is applied. Consequently, the particles emitted from the sputter get 7 by sputtering receives the electrons from the electron emitting part 1 to form negative ions.

Abstract: PROBLEM TO BE SOLVED: To aquire the image data of resolution higher than performance provided for an image input device by extracting an overlapped part from plural pieces of partially acquired image data and linking the entire image data as one piece of image data. SOLUTION: Inside a work memory 22 of a data processing means 2, a non-synthesized data buffer for data, to which synthesizing processing is not performed, and a data buffer for confirming image data, for which the overlapped part required for synthesization can not be discovered, are prepared. All the image data to become the base of synthesization are inputted to the non-synthesized data buffer and the image data to become the reference of synthesization are extracted.  Concerning the data to become the reference and the data to become the target of synthesization, it is inspected whether the part overlapped with peripheral sections as a center exists or not and when such a part does not exist, it is discriminated that the data at a position away from the reference image are selected as the synthesizing target so that the image of synthesizing target is saved in the confirmed data buffer. When such a part exists, the reference image and the synthesizing target image are linked and defined as a new reference image.

Filed: 1989-03-15
Abstract: PURPOSE:To increase an analytical speed and to enhance the reliability of data by always allowing a solvent to flow to all of columns possible to combine to hold the outputs thereof to a stable state and selecting an arbitrary column by changing over a valve to perform analysis. CONSTITUTION:In a case not used in analysis, two adjacent columns are mutually connected by four-way change-over valves 4-8. A six-way rotary change-over valve 2 connects a pump to a column A and other valve 3 connects a column F to a receiver and the medium from the pump passes through all of columns A-F to preliminarily hold the outputs of the columns to a stable state. In the case of analysis, the valve 2 connects the pump to the required column and the pump 3 connects a detector to the required column. By this method, the arbitrary column is selected from the columns in a stable state only by changing over valves and an org. compound can be analyzed rapidly with reliability.

Filed: 1980-05-08
Abstract: PURPOSE: To improve the turbine output in a condensing apparatus by disposing both a condenser having high vacuum degree and another condenser having lower vacuum degree than the previous condenser at the heat so that the exhaust vapor of a turbine flows from the condenser to the another condenser, thereby heating the condenser water with exhaust vapor.  
     CONSTITUTION: An air cooled condensor 9 to which exhaust vapor is introduced from the second low pressure turbine 5 of low exhaust gas pressure side is disposed at higher position than a tubular condenser 7 to which exhuast gas from the first low pressure turbine 4 of high exhaust gas pressure side is introduced. The condenser 7 connected to a cooling tower 13 has lower vacuum degree than the condenser 9 connected to a condensed water reservoir 14, but the condensed water in the reservior 14 is introduced, due to the head difference overwhelming the condenser 9, to the top of the condenser 7, and is heated to saturated vapor temperature to be mixed with the condensed water in the condenser 7. Since the condensed water of the amount corresponding to one half of the exhaust vapor amount of the tubrine plant 1 is reheated with this heat thus obtained, it can reduce the heating vapor extract amount.

Title: Level display circuit
Inventor: NAGATA YASUO
IPC: G11B20/04
Filed: 1979-05-17
Abstract: PURPOSE:To maintain the operation of a high-level element even after the disappearance of an input signal by making fixed connections between the 1st group of transistors, supplied at their bases with an output divided by a resistance corresponding to the valve of a level, and the 2nd group of transistors and several display driving elements. CONSTITUTION:Dividing ratios of resistances 21-28 are so set that while base inputs of transistors (TR) 17-20 increase gradually, a difference in base input will increase above VBE. Then, TR17-20 are grounded in common via resistance 33 and their collectors are connected via resistances 29-32 to the bases of TR13-16, whose collectors are further connected to display elements 1-4. The emitters of TR13-16, on the other hand, are connected to electric power source 12. Once an input arrives at the input terminal, TR5, 6, for example, conduct and display elements 1 and 2 are put into operation. Meanwhile, TR17 is OFF and 18 and 14 are both ON. A self-holding circuit is therefore constituted, so that high-level display elements 2 will keep on operating even after the disappearance of the input.
