Title: Sample for electron microscope and manufacture thereof
Inventor: SHIMIZU KEIJI
IPC: G01N1/32
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To enable observing of a fine crystal defect of a silicon single crystal with a transmission electron microscope by performing an ion milling of a silicon single crystal substrate and an oxidizing treatment of a damaged layer to remove the damaged layer subsequently. SOLUTION: A silicon single crystal substrate is cut by a diamond cutter and made into a test piece to match a sample holder. Then, an observing surface 1 is ground thinner from a plane on the opposite side thereof with a planar grinder or the like and the test piece 1 is worked by a ball grinder to be thinner only at the center thereof. Thereafter, an observing part of the test piece is made thinner by an ion milling device down to several hundred nm or less. Then, the test piece is washed by a solution having an oxidizing action such as standard cleaning 1 (R) and a silicon oxide film 3 is formed on the entire surface of the sample piece 1, when a part of the whole of a damaged layer 2 is oxidized.  Then, the sample piece 1 having the oxidized damaged layer 2 thereon is treated by a buffer hydrofluoric acid solution to remove a part or the whole of the damaged layer 2 on the sample. When the damaged layer is thick, this removing action is repeated to complete a sample having no damaged layer.

Title: Absorption type cold water or hot water heater
Inventor: YAMASHITA TERUMI
IPC: F25B15/00
Filed: 1993-06-07
Abstract: PURPOSE:To provide a stable liquid surface level of solution within each of high temperature regenerators by a method wherein an inside part of a low temperature regenerator is divided into two chambers during a heating operation and a flowing passage is made independent at each of the high temperature regenerators. CONSTITUTION:Vapor of refrigerant generated by heating solution within a high temperature regenerator 9 during a heating operation is guided to a hot water heater 13 and returned back to the high temperature regenerator 9. During cooling operation, vapor is flowed to a low temperature regenerator 10 through a refrigerant vapor pipe 14. Since a duct 15 of the low temperature regenerator 10 is divided with a refrigerant vapor pipe 1 extending from each of the high temperature regenerators 9, its function performed during cooling operation does not vary and an independent cycle is produced between each of the high temperature regenerators 9 and a hot water heater 13 and the refrigerant vapor in one regenerator does not flow into the other high temperature regenerator 9. Accordingly, since the refrigerant is circulated independently within each of the high temperature regenerators 9, a level of liquid surface of solution within the high temperature regenerator 9 is different from each other in each of the high temperature regenerators 9, so that it is possible to prevent the heater from being stopped due to a lowering of the liquid surface.

Abstract: PURPOSE:To easily discriminate a troubled place and to shorten a repairing time, by constituting the title printer so that the trouble of the detection means positioned in the scanning direction of a recording head is detected by a separate detection means to print a trouble message. CONSTITUTION:A step S1 shows a pre-processing part and a counter SC counting the number of times of right shift processing is cleared in a step S2. In a step S3, the carriage of a printer is shifted by one character to the right and, in a step S4, it is discriminated whether the output signal from the position detector HP of a printer unit PR is outputted. This operation is repeated and, when the position detector HP is brought into contact with a carriage and a detection signal is outputted, the processings of steps S9, S10 are performed. When said detection signal is not outputted, 1 is successively added to the counter SC in a step S5 and, when the position detector HP is normal, steps S3-S6 are repeated and cleared by the discrimination of the step S4. When the value of the counter SC reaches a predetermined value, it is judged that the position detector HP gets out of order to advance to a step S7 and the message thereof is transmitted to a printing register PRR and printing is performed in a step 8. Therefore, abnormality can be determined as present and a processing time can be shortened.

Title: High-purity silica and its preparation
Inventor: KASHIWASE HIROYUKI
IPC: C01B33/187
Filed: 1984-07-03
Abstract: PURPOSE:To obtain high-purity silica having low radiation and low content of alkali substance, by reacting a mineral acid with an aqueous solution of alkali silicate while keeping a reaction system in a strong acidity by adding the solution to the acid, treating formed silica precipitate with a mineral acid. CONSTITUTION:An aqueous solution of alkali silicate having >=20wt% SiO2 concentration is added to a mineral acid, and the reaction is carried out while keeping always a reaction system in a strong acidity of <=1pH, to form silica precipitate. Then, formed silica precipitate is treated with a mineral acid, to give the aimed high-purity silica having contents of impurities of <=10ppm Na, <=1ppb U, and <=1ppb Th. With regard to radioactive materials, contents of U and Th in silica are preferably <=1ppb, respectively, when the content exceeds 1ppb, silica unfavorably causes occurrence of soft error when it is used as a filter for a resin sealing agent of highly integrated IC, LSI, or VLSI. When content of ionic impurities represented by Na exceeds 10ppm, corrosion occurs easily, which is unfavorable.
