Title: Electron beam exposure
Inventor: KAI JUNICHI
IPC: H01L21/30
Filed: 1985-08-02
Abstract: PURPOSE:To improve the stability of a control system by a method wherein the amount of exposure in relation to the variation of the current density of an electron beam is compensated by maintaining the cycle of the system clock constant and by increasing and decreasing the blanking time so as to operate the whole system with a constant clock cycle. CONSTITUTION:The amount of exposure in relation to the variation of the current density of an electron beam is compensated by adjusting the exposure time. At that time, the cycle of the system clock that is a sum of the exposure time and the blanking time is held at a constant value, and the blanking time of an electron beam is increased and decreased. The variation of the current density of the electron beam is not so large and generally remains within a few %, and there will be no problem even if the blanking time of the electron beam is increased and decreased in such amount. Then, it is made possible to allow a series of exposure processes with a system clock with a constant cycle, thereby improving the stability of the control system.

Inventor: TANAKA YUTAKA
IPC: G01C15/00
Filed: 1983-09-19
Abstract: PURPOSE:To tilt an optical horizontal plane in a specified direction at a large angle, by positioning the focal point of an objective lens, with suspending points of an automatic correcting lens as supporting points, making the objective lens to perform circular movement, and reducing abberation. CONSTITUTION:A device is constituted by light source parts 1 and 1', an automatic correcting mechanism part, an optical tilting part, and an optical-plane setting part. The optical tilting part rotatably supports a frame body 4', in which an objective lens 4 is fixed, with a shaft 15, which crosses a shaft X-X' that suspends the automatic correcting lens 10, as a rotary center. The frame body 4', i.e., the object lens 4, can be tilted by the operation of a micro-knob 11 at the rear of the frame body 4' with the shaft 15 as the center. In this constitution, the abberation of the objective lens 4 can be reduced, and the light beams become the parallel light beams without enlarging the automatic correctting lens 10. The light beams are not converged or dispersed even though the tilting device is provided.

Title: Optical character reader
Inventor: TERASAKI MASANORI
IPC: G06K9/20
Filed: 1990-06-29
Abstract: PURPOSE:To normally recognize a character by only giving simple correction by performing character recognition by excluding the character on a character entry field corresponding to a mark decided by a mark position deciding means from an object to be processed. CONSTITUTION:The character recognition is performed by excluding the character on the character entry field corresponding to the mark decided by the mark position deciding means from the object to be processed. The mark is entered at the position of the mark entry field 12 corresponding to the position of the mark entry field 12 corresponding to the position of the character desired to correct on the character entry field 11, namely the position of a mark entry field 12 corresponding to the position just above a wrong character, and the correct character is entered in the next frame of the character entry field 11. Thus, the character recognition can be normally performed by only re-entering the correct character in the character entry field, and in addition, entering the mark at the corresponding position of the mark entry field.

Title: Reactive ion beam etching device
Inventor: WATAKABE YAICHIROU
IPC: H01J37/08
Filed: 1983-09-17
Abstract: PURPOSE:To contrive the prolongation of a W filament by a method wherein the W filament which radiates thermal electrons to generate reactive gas ions by activating a reactive gas in an ion source chamber is stably operated in the atmosphere of an inert gas. CONSTITUTION:For example, Ar gas is introduced into a metallic pipe 8, the reactive gas being introduced into the ion source chamber 1, and a negative high bias voltage of several hundred V being then impressed on an accelerating electrode 5 through a window 4. Next, the thermal elctrons are radiated by heating the W filament 3. The Ar gas is activated and then comes to the state of plasma of isolation into Ar ions and electrons. The plasma penetrates into the reactive gas outside the metallic pipe 8 through numerous small holes formed in the pipe wall and then activates the reactive gas. The positive ions of the reactive gas are led out through the window 4 by the negative high bias voltage impressed on the electrode 5, and performs etching by irradiating the film to be etched formed on the main surface of an Si wafter 6. In this case, the filament 3 is protected by the inert gas.

Title: Kanji conversion processor
Inventor: HAMADA AKIRA
IPC: G06F17/22
Filed: 1988-07-08
Abstract: PURPOSE:To improve the ability of a word processor by giving continuously the preference to a word registered in a learning buffer according to the using situation of the word. CONSTITUTION:A memory which records the using situations of words is added to a learning buffer 5 and the using situations of the recorded words are checked and recorded. When a word is excluded out of the buffer 5, the recorded contents of the word are checked to decide whether the preference is continuously given to the word or not. If so, the word is registered into another memory means 4 having the lower priority than the buffer 5. Thus such words that exceed the storage capacity of the buffer 5 can be registered into the means 4 according to the using situations of those words. Then these words can be called out as necessary.

The deposited crystal is further separated from the liquid, then washed with a 10-90% sulfuric acid, subsequently washed with a 0-20% sulfuric acid and then hydrolyzed to afford hydrated titanium dioxide.  The hydrated titanium dioxide is then baked to provide high-purity titanium dioxide having contents of Nb and Zr of <=50ppm expressed in terms of Nb2 O3 and <=20ppm expressed in terms of Zr.

Title: Non-oxidation welding method in liquid for electric welded pipe
Inventor: SHIMOMURA TAKAYOSHI
IPC: B23K11/08
Filed: 1985-08-06
Abstract: PURPOSE:To enable the non-oxidation welding with less welding defects even the alcohol concentration being low by performing the welding by sealing the welding zone of an electric welded pipe with the deaerated water including alcohol. CONSTITUTION:The shielding liquid 2 containing >=1% liquid showing no oxidation even with its vaporization such as alcohol, with deaeration treatment as well is contained inside a shielding liquid tank 1. The welding is performed by locating the weld heating part 6 of an electric welded pipe therein with feeding this liquid 2 into a shield tank 7. The oxidation of the weld heating part 6 is therefore prevented with being sealed by the shielding liquid. In this case, the number of defects can be reduced to 1/3-1/4 in the past even in case of the alcohol concentration being 1% and the number of defects can be made zero almost in case of more then 10%. Consequently the cost in reduced and the risk of ignition can be reduced as well.

CONSTITUTION:A thick CVD oxide film 12 is deposited on a silicon substrate 11; it is patterned; a first recessed part surrounded by the oxide film 12 is formed; after that, a polycrystalline silicon film 13 is deposited on the surface by a low-pressure CVD method. A photoresist 14 is etched on the whole surface by a CDE method or the like; it is left only in a second recesssd-part region of the polycrystalline silicon film formed in the first recessed part; it is patterned. Then, boron is used as an ion species; ions are implanted; a carbonization layer 15 is formed on the surface part of the photoresist 14. Thereby, an etch rate of the photoresist 14 by a reactive ion etching operation is reduced largely; an excellent mask effect can be obtained. As a result, a pattern can be formed without a decrease in a film thickness of the polycrystalline silicon film 13.
