Abstract: PURPOSE:To attain input of Roman characters with no discrimination of 'N' by switching automatically the conversion of the vowels or contracted sounds following 'N' into 'UNA', 'UNI', etc. or 'UNYA', 'UNYO' and 'UNYO'. CONSTITUTION:When 'ANI', for example, is inputted by a Roman character input means 1, the 'NI' is converted into 'NI' (cursive form of Japanese syllabary) and then into 'ANI' according to the Japanese rendering of KANA ('1' in a table by a Roman character/KANA (Japanese syllabary) converting means 2. Then the 'ANI' is converted into 'ANI', a KANJI (Chinese character). A KANA/KANJI conversion end signal generating means 7 informs with the end signal the end of a single KANA/KANJI converting action to the means 2. Thus the 'NI' is turned into 'UNI' (cursive form of Japanese syllabary) together with the 'ANI' turned into 'ANI' (cursive form) respectively by the means 2 in accordance with the Japanese rendering of KANA '2' in the table. Then 'ANI' (KANJI) is obtained by the means 3 and the dictionary 4.

Title: Method for manufacturing gas diffusion electrode for battery
Inventor: OOO FUMIO
IPC: H01M4/88
Filed: 1983-04-06
Abstract: PURPOSE:To produce a gas diffusion electrode excellent in battery characteristics with high productivity, by uniformly attaching manganese oxide having high catalysis to active carbon closely packed in a sheet form by use of an ultrasonic wave. CONSTITUTION:Active carbon very closely packed in a sheet form having porosity of 20-30% and weight per unit area of 350-600g/m<2> is submerged in an ultrasonic bath filled with a water solution of manganese sulfate. Caustic alkali is added to the solution to alkalinize the same while applying the ultrasonic vibration to the porous portions of the sheet-formed active carbon, whereby manganese hydroxide is produced there. The manganese hydroxide is oxidized by blowing oxygen into the bath and manganese oxide is thereby deposited and developed. Thereafter, by heat-treating the active carbon in a non-oxidizing atmosphere, a predetermined amount of highly catalytic manganese oxide can be attached to the active carbon, and then the gas diffusion electrode 2 can be produced by pressing, with a press or the like, the same into a predetermined thickness.

Title: Preparation of sample for analysis
Inventor: HOZAWA KAZUYUKI
IPC: G01N1/28
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a sample for analysis, to shorten the time for preparation of the sample, and to improve the accuracy of quantitative determination of contamination of the surface of a base, of which the amount of contamination is unknown, by dripping a sampling liquid by a small quantity in several times repeatedly onto one point of the surface of the base being heated. SOLUTION: A base 11 for a standard sample is set on a jig 12 and heated to a temperature of 110 deg.C, by using a temperature regulator 21, in a state wherein the shape of the base 11 is changed to a recessed one with the rear thereof kept in vacuum. A standard solution of which the atomic concentration is known is sampled by 100μl (the atomic weight is equivalent to 1×10<14> atoms/cm<2> ) by using a micropipette 22. The micropipette 22 is fixed at the center of the base 11 by using micropipette supports 23, 24 and 25 and a sampling liquid 15 is dripped by 2μl in 50 times separately to the center of the base 11. The result shows that the dimension of a trace of the dripped liquid is 2mm or less with respect to any samples.  The detection efficiency of a working curve of the standard sample for the working curve is improved in values of the curve to be about three times better than that of the working curve prepared by a usual method.

Title: Device for detecting intake air quantity of internal combustion engine
IPC: G01F1/72
Filed: 1992-03-17
Abstract: PURPOSE:To accurately detect the intake air quantity of an internal combustion engine irrespective of the output varying state of an air flowmeter, whether in a transient state or pulsating state, by discriminating the varying state and correcting the intake air quantity only when the varying state is in the pulsating state. CONSTITUTION:When the output varying state of an air flowmeter 16 is in a pulsating state, an electronic control circuit 18 calculates the maximum and minimum values and ripple factor of a tentative air quantity. Then the circuit 18 reads the rotating speed of an internal combustion engine 11 from the signal of a rotational angle sensor 19. An actual intake air quantity can be obtained by reading out the correcting amount corresponding to the ripple factor and rotating speed and correcting the tentative air quantity by using the correcting amount. Thus a tentative air quantity which well coincidents with the actual intake air quantity can be obtained by correcting the tentative air quantity when the varying state is in the pulsating state in which the tentative air quantity found from the output of the flowmeter 16 does not coincide with the actual intake air quantity. When the varying state is in a transient state in which the tentative air quantity well coincides with the actual air quantity, such correction is not required. Therefore, the intake air quantity can be accurately detected irrespective of the varying state, whether in the pulsating state or transient state.

Abstract: PURPOSE:To restrain back fire and stabilize combustion upon weak combustion by extending a multitude of partitionings of a burner cap radially from the upper surface of a burner body. CONSTITUTION:The burner cap 4, provided with a multitude of partitionings 6'' and the openings thereof, is fitted detachably to the burner body 2 to form flame ports 7 on the circumference of the burner cap 4 and flame port paths 6 at the inside of the same cap 4 while the partitionings 6'' of the burner cap 4 are extended radially from the upper surface of the burner body 2.

Title: Formation of film by utilizing vapor phase reaction
Inventor: HASHIMOTO YOUICHI
IPC: C23C16/04
Filed: 1984-03-27
Abstract: PURPOSE:To form a local covering in short time at a low cost without post working by concealing the non-film part of a work with a cover and closing the spacing between the cover and the work by a difference in the coefft. of thermal expansion between said cover and material to be worked in the stage of forming the film. CONSTITUTION:The non-film part of a circular cylindrical material 5 to be worked is locally concealed by a cover 9. The cover 9 is formed of an ''Invar'' alloy and has he inside diameter slightly larger than the outside diameter of the material. Such material is set on the tray 7 in a reaction furnace and the inside of the furnace is heated. Only the gaseous H2 is passed until the reaction temp. is attained. The material 5 expands thermally in an equal direction but the cover 9 does not expand thermally. The spacing between the material 5 and the cover 9 is thereby closed and the part of the material 5 except the exposed part can be shut off from the reactive gaseous atmosphere. If the temp. is lowered after the formation of the film, the material 5 restores the original size and can be therefore easily removed from the cover 9.
