Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a semiconductor device whereby a buried layer having no surface defect can be produced, by preventing the auto doping from occurring into a substrate surface to be a region for forming a buried layer and possibly not damaging the surface. SOLUTION: A region for forming a buried layer is opened on a p-type substrate 1, a resist 2 is formed on the surface, an opening not forming the resist 2 is regarded as a window region, an impurity (B) is ion-implanted into the substrate 1 from the window region to form an ion-implanted (p+-)region, the resist 2 is removed, the substrate 1 is annealed in a nonoxidative atmosphere. Further, the p+-region is expanded while gradually raising temperature of the substrate 1 to form a p+-buried layer 4, and at the same time an epitaxial layer 5 is grown at a time at which the p+-region does not reach the surface of the substrate 1.

Title: Air separator
Inventor: FUJIMORI KANJI
IPC: F25J3/04
Filed: 1989-05-17
Abstract: PURPOSE:To simplify a system by a method wherein a pressure in a condensor is adjusted by a turbine inlet valve and an original air discharging valve, an amount of liquid nitrogen is increased and then a turbine bypass line and a bypass valve are eliminated. CONSTITUTION:It is necessary to keep a pressure in a nitrogen condensor 13 constant in order to make a pressure of product nitrogen constant. Due to this fact, a bypass valve is eliminated and a pressure in the condensor is adjusted by a turbine inlet valve 7 and an original air discharging valve 6. A pressure in the nitrogen condensor 13 is detected by PIC 11 and as the pressure in the nitrogen condensor 13 is increased, the turbine inlet valve 7 is gradually opened. Provided that the turbine 5 has its own dangerous number of revolution so as to prevent its over-speed rotation. As the number of revolution reaches a predetermined number of revolution, an opening operation for the turbine inlet valve 7 is stopped and then the original air discharging valve 6 is gradually opened. In case that an amount of air supplied to an expansion turbine 5 is less, it is adjusted by the turbine inlet valve 7 so as to apply a pressure loss, thereby it is possible to keep a pressure of the nitrogen condensor 13 constant.

Title: Magnetic head
Inventor: KIMURA AKIRA
IPC: G11B5/127
Filed: 1987-05-19
Abstract: PURPOSE:To stabilize the interface between a head and tape so as to improve the reliability of the head, by making constitutions of inclined patterns of ferrite tracks equal to each other when head sliding directions of heads are used as a reference. CONSTITUTION:A head, whose operating gap has a positive (counterclockwise) azimuth angle theta, is worked with an azimuth angle of 2theta when grooves 3A and 3B controlling a track width are formed and, when this magnetic head is compared with magnetic heads produced by conventional methods, the inclined direction of a ferrite track constituted of a ferrite core and mold glass is made symmetrical when the head sliding direction is used as a reference. Therefore, the sliding surface of another head having a negative (clockwise) azimuth angle in made equal to that of the head having the positive azimuth angle in shape, especially, in the inclined pattern of the ferrite track. Therefore, the difference in head interval caused by a change in shape of the sliding surface with lapse of time due to the difference in wear resisting property of the ferrite core and mold glass, which is seen in conventional magnetic heads when the heads are slid on tapes for a long time, can be eliminated and a stable interface is obtained between this magnetic head and tapes.

IPC: G06F17/27
Filed: 1988-05-20
Abstract: PURPOSE:To improve the processing speed for correct description of KANJI (Chinese characters) by extracting the words set before and after a character string expressing the higher-lower rank relation and converting both extracted words into the KANJI of the upper and lower rank concept words respectively by reference to a dictionary where the language meanings are systemized and stored. CONSTITUTION:The sentences supplied in the Roman characters, HIRAGANA (cursive form of Japanese syllabary) and KATAKANA (square form of Japanese syllabary) are held by an input sentence holding means 11. While a holding means 12 holds a higher-lower rank relation expressing character string which shows the higher-lower rank relation of languages. A deciding means 13 decides whether the sentence held by the means 11 contains the higher-lower rank relation expressing character string or not by reference to the means 12. Based on the result of this decision, an extracting means 14 extracts the words set before and after said relation expressing character string. Then a substitute means 15 refers to a dictionary 16 where the language meanings are systemized and stored and substitutes the plural extracted words for the KANJI of the higher and lower concept words corresponding to said words respectively. As a result, the processing speed is improved for the correct description of KANJI.

Title: Method for measuring total reflection infrared absorption spectrum
Inventor: ISHIKAWA MEGUMI
IPC: G01N21/35
Filed: 1985-06-07
Abstract: PURPOSE:To analyze the depth in a total IR light wavelength region at one time by using an inorg. compd. having no absorption in the wavelength region of IR light as a spacer. CONSTITUTION:The IR light 2 emitted from an IR light source 1 passes through a Michelson interferometer 3, is made incident on a crystal 5 in a sample holder 4 and is totally reflected by the boundary between the crystal 5 and the spacer 6. The inorg. compd. such as ZnSe or PbF2 which has the refractive index lower than the refractive index of the crystal 5 and is transparent to IR light is used for the spacer 6. Part 7 of the incident IR light bleeds to a measuring sample 8 beyond the boundary, is reflected by receiving the effect of the absorption by the sample 8 and is detected by a detector 9. The detected light is processed by a data processor 10 and the total reflection IR absorption spectrum is obtd. The penetration depth of the IR light 7 penetrating into the sample 8 in the stage of total reflection changes when the thickness of the spacer 6 is changed. The depth analysis is thus made possible. The depth in the total IR wavelength region is thereby analyzed without receiving the effect of absorption by the spacer.
