Abstract: PURPOSE:To obtain a Si nitride film having a composition close to a stoichiometry-like composition by mixing Si into NF3 or N2F4 or a raw material gas while using NF3 or N2F4 singly or as a mixed body when Si is directly nitrified employing N2, NH3, N2H6 or the like as the raw material gas. CONSTITUTION:Clean Si wafers 10 are supported to carbon bases 11 coated with SiC, and the inside of a reaction pipe 1 is decompressed up to 10<-3> Torr. The predetermined quantities of NH3 and NF3 are introduced, and the flow rate of N2 is adjusted 6 to keep its pressure at approximately 1 Torr. High-frequency power is given to form the plasma of NH3 and NF3 in th pipe, and the wafers 10 are heated at approximately 1,000 deg.C. When power is interrupted after a fixed time passes, the supply and exhaust of NH3 and NF3 are stopped, the inside of the pipe is filled with N3 and the wafers are extracted, a minute thin- film having a property close to bulky Si3N4 is obtained. According to such constitution, the film thickness of several times as large as conventional examples is acquired, a virulently poisonous substance is not formed in a reaction, and the mixing of impurities is also extremely little because a halogne compound containing unnecessary atoms is not used.

Filed: 1991-02-15
Abstract: PURPOSE:To restrain a dimensional conversion difference from occurring in an etched object in a dry etching method where a resist mask reversely tapered in cross section is used. CONSTITUTION:A photoresist pattern 4 formed of negative type chemical sensitization resist material is formed into a reversely tapered shape in cross section due to its photosensitive characteristics.

Abstract: PURPOSE:To form a sharp image in a short time by calculating picture elements in an unflat area by a method which requires a long time, but obtains an accurate value and estimating values for other areas by a high-speed method. CONSTITUTION:A brightness calculator 2 is supplied with object data and light source data. A control part 5 scans an image at predetermined intervals (d) and supplies the address of an object picture elements to the brightness calculator 2. The calculator 2 calculates the value of the picture element at the position and writes it in an image memory. A control part 5 supplies vertex addresses of a square area in the image memory 1 and outputs picture element values of those addresses from the image memory 1 to a flat area detector 4. The flat area detector 4 decides flatness on the basis of them and passes the result to the control part 5. When the area is flat, the control part 5 controls a picture element estimating device 3 so as to estimate picture elements in the square area from the picture elements at the vertexes.

Abstract: PURPOSE:To securely detect an abnormal stack in reaction containers which are discharged after analysis and stored by discriminating whether or not reaction containers are stacked outside a storage container by using the output of a detecting means. CONSTITUTION:A reaction container supply mechanism 6 supplies reaction containers to a turntable 3 in order, which conveys the reaction container 1 on a reaction line to take a specific analysis and reaction containers 1 after the analysis are disposed by a scraping-out mechanism 7 from the table 3 are stored in the storage container 8.

Title: Frequency converter
Inventor: TEZUKA TSUTOMU
IPC: G02F2/02
Filed: 1990-02-26
Abstract: PURPOSE:To obtain the frequency converter which has good efficiency by specifying the frequency relation among pump light,input signal light, and output signal light. CONSTITUTION:Four waves which are the input signal light of frequency fi, the pump light of frequency fP1 which is several GHz different from fi, and pump light of frequency fP2 different from fP1 are mixed and when the intensity of the input light is much less than the pump light intensity, two frequency- converted light beams having frequencies fc<+> and fc<-> are generated. Consequently, it can be considered that there are the input signal light, two pump light beams, and three frequency-converted light beams, i.e. six frequency light components in a semiconductor laser amplifier 13 or semiconductor lasers 12 and 13. When the signal light is so converted that its frequency fi increases, a frequency selecting element 14 selects the fc<+> among the six frequencies and when the light is converted so that the frequency decreases, the fc<-> is selected and outputted. Consequently, highly efficient frequency conversion can be attained.

Abstract: PURPOSE:To uniformly set thickness of a painted film which is applied and formed on the surface of a supporting body by dividing cylindrical supporting bodies into two groups by the same number of pieces, drawing up the other group at the same moving speed from in a paint liquid, when one group is immersed into the paint liquid, and keeping the paint liquid surface in a container constant at the time of forming the paint film. CONSTITUTION:With regard to two groups of cylindrical supporting bodies 13A, 13B of the same number of pieces each, one is immersed into a paint liquid 11 and the other is drawn up from in the paint liquid 11. That is, the liquid level is lowered by drawing up the cylindrical supporting body 13A in the paint liquid 11 by a portion by which the liquid level 11A of the paint liquid has ascended by the cylindrical supporting body 13B which is immersed into the paint liquid 11. In such a way, by keeping a position of the liquid level constant all the time while applying to the paint liquid and keeping the height of a first liquid level high, a space part on the liquid level is decreased. In such a way, drying speed of the paint film is kept constant in spite of the fluctuation of a pint film forming position on the cylindrical supporting bodies 13A, 13B, and the paint film of uniform thickness can be applied and formed.
