Filed: 1991-03-30
Abstract: PURPOSE:To make possible stable use at the time of high temperature of even polyimide and the like coated on the outer wall of a column by setting a fan in a column drum and introducing inert gas. CONSTITUTION:A sample is infected by a cylinder and the like from an infection opening on the upper part of a column drum 1 and a detector 3 detects the separated sample. A fan 5 in which a capillary column 4 and a rotary shaft 10 are supported by an airtight bearing 9 is set in the inside of the drum 1. The temperature of the inside of the drum 1 is made uniform and the inside thereof is agitated by the use of the fan 5. Nitrogen gas N2 of inert gas is supplied to the drum 1 through a flow controller 6 and an introduction tube 7 to purge the air of the drum 1. Thereby the pressure of the space of the drum inside is heightened by inert gas a little, so that the air does not come into the drum 1. Accordingly the quantity of oxygen coming into contact with a column surface is very little and there is almost no damage of the column surface.

Filed: 1985-04-30
Abstract: PURPOSE:To modulate lots of data with simple constitution by providing a count section counting a clock pulse and a comparison section comparing an output signal of the count section with a digital input signal to be modulated. CONSTITUTION:A counter 11 constituting the count section counts a clock pulse CLK with a prescribed frequency, outputs sequentially 4-bit binary data y1-y4 and sends them to a comparator 12 being a component of a comparison section. The comparator 12 compares 4-bit binary data x1-x4 with the data y1-y4 and when x<y exists, an H level signal is outputted, and when x>=y exists, an L level signal is obtained. A pulse width modulation signal going to an H level by a time (clock number) in response to the level of the data (x) to be modulated is obtained as the output signal of the comparator 12. Through the constitution, the sampling time of pulse width modulation is operated in the period of clock number 16 and no reset pulse is required.

Title: Magnetic recording medium
Inventor: FUJITA MINORU
IPC: G06K19/00
Filed: 1987-04-17
Abstract: PURPOSE:To improve security with simple constitution by combining and using >=3 kinds of patterns which are different in coercive force so as to meet information. CONSTITUTION:The patterns >=3 kinds which are different in coercive force, for example, high, middle and low coercive force patterns (successively 2, 5, 3) are combined in accordance with the information and are provided on a substrate 1. The high coercive force pattern 2 is previously magnetized in a desired direction and is preferably given with a part of the information in the magnetization direction. Since >=3 kinds of the patterns (2, 5, 3...) which are different in the coercive force are used to constitute this medium in such a manner, the information in the decision of truth or false is intricated and the security is improved. Residual magnetization is generated only in a part of the pattern 2 which is high in the coercive force even if an external magnetic field is applied to the medium for the purpose of reading the information. The patterns 3, 5 of the low coercive force are, therefore, not detected even if the information such as, for example, code for deciding the truth or false is attempted to be deciphered by a magnet viewer, etc. The security is thereby enhanced with the simple constitution even if the medium is not subjected to a special treatment such as demagnetization. This medium is helpful for preventing ill use, falsification and forgery of the medium.

Abstract: PURPOSE:To prevent deterioration in surface morphology by exposing inside of a dry etching apparatus to hydrogen plasma before etching. CONSTITUTION:When a III-V compound semiconductor is to be etched, before etching, that is with a specimen 6 not yet installed on a specimen stage 5, the inside of a dry etching apparatus is exposed to hydrogen plasma. Thus the inside of the apparatus such as an ion extractor electrode 1 is cleaned so that substances for preventing good etching such as re-attached substance existing in the apparatus can be removed, Thus etching can be performed in clean atmosphere thereby obtaining good surface morphology same as that before etching can be obtained after etching.
