Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To easily prepare a desired document including a Chinese compound word, etc., by dispensing with the handwritten input of all the readings and KANJI (Chinese characters) in a character string desired to input. SOLUTION: In the input area 12a of a display (display screen) 15 obtained by providing input devices 12 consisting of tablets, at the time of inputting a handwritten character by surrounding with a circular mark, the circular mark is judged to be inputted based on handwritten stroke data stored in a stroke storage part in a storage device, and then the character recognition of a single KANJI is executed based on the stroke data except this circular mark. At the same time, a Chinese compound word with the recognized single KANJI as the head is retrieved from a Chinese compound word dictionary in a dictionary data storage part to display the first Chinese compound word in an output area 15a and to display the second and succeeding Chinese compound words in a candidate display area 15b.  Then, at the time of selecting a desired Chinese compound word by touching operation, the selected Chinese compound word is replacedly displayed in the output area 15a to be established.

Title: Preparation of polymer particle
Inventor: JIYON REONAADO MIYUURUBAUAA
IPC: C08F2/00
Filed: 1994-11-14
Abstract: PURPOSE: To produce a polymer particle having a very small content of rather large particle aggregates and being uniform in size by forming droplets of an ethylenically unsaturated monomer and a nonreactive compound in an aqueous medium containing a particulate suspension stabilizer.  
     CONSTITUTION: In the formation of droplets of an ethylenically unsaturated monomer and a nonreactive compound in an aqueous medium, the aqueous medium contains a particulate suspension stabilizer, and the nonreactive compound has a solubility lower than that of the monomer. A first mixture is formed from the nonreactive compound having a log P (calc) of at least 3 and the monomer having a long P (calc) lower than that, and a second mixture is formed from water, the particulate suspension stabilizer, and a promoter. The first and second mixtures are mixed with each other under high shear to form a discrete phase of droplets of the first mixture in a continuous phase of the second mixture and to thereby determine the size of the droplets by limited coalescence.

Title: Method for predicting dimensional change of sintering of metallic powder
Inventor: TAKAGI SHIGEAKI
IPC: G01N9/00
Filed: 1989-10-30
Abstract: PURPOSE:To predict the dimensional change of molding at the time of sintering and to improve the dimensional accuracy of parts by two-dimensionally and quantitatively measuring the sectional shape of metallic powder particles to determine a shape coefft. and obtaining the correlative relation between the shape coefft. and the dimensional change of sintering. CONSTITUTION:The particles of the metallic powder are embedded in a resin and are polished. The sectional images are magnified by an optical microscope and are two-dimensionally observed. The shape coefft. is determined by microscopic processing. The shape coefft. is adequately the max. diameter of the section of the particles or the ratio between the circumferential length and the sectional area. And the shape coefft. of the particles is quantitatively measured by the prescribed method and the correlative relation between the shape coefft. and the dimensional change of sintering is obtained. The powder characteristics, such as shape, grain size and compsn. of the particles affect the dimensional accuracy as well and, therefore, a weight correlation is used in the case of prediction of the dimensional change by the shape coefft. and the plural powder characteristic parameters. The dimensional change is predicted by the characteristics of the metallic powder when the correlative coefft. is previously determined in such a manner.

Title: Production of vertical magnetic recording medium
Inventor: TAKAHASHI YOSHIO
IPC: G11B5/852
Filed: 1984-12-28
Abstract: PURPOSE:To reduce the disorder in anisotropy in the thickness direction of a film by impressing a magnetic field vertical to a substrate by using 2 sets of magnets which are provided on each rear surface side of the substrate and a target both of which are arranged opposite to each other, and giving vertical induced anisotropy to a film in the early stage of formation whose crystal is not oriented yet. CONSTITUTION:Two sets of magnets 61 and 62 are arranged to generate a magnetic field in the direction as shown by the arrow or almost vertical to the surfaceoof a substrate between a target 21 and a substrate 41 on which a magnetic film is to be formed. The intension distribution of the magnetic field can be determined by the ship and size, magnetization intensity, and arrangement of the magnets, since the substrate on which a magnetic film is to be formed is nonmagnetic and the magnetic permeability of the target (Co-Cr) is low. Accordingly, when a high-frequency voltage is impressed between the target 21 and the substrate 41 in the vertical magnetic field and the surface of the target is sputtered, and sputtered particles (Co-Cr particles) are deposited on a 'Permalloy(R)' layer of the substrate 4, then the crystal M of the magnetic body having the magnetism in the direction as shown in the figure is deposited under the action of the vertical magnetic field, and consequently the Co-Cr magnetic film having excellent orientation can be formed.

Abstract: PURPOSE:To read an original picture in synchronism with any of picture processing units having different print speeds by providing a means applying drive control of a motor moving a read optical system or an original in synchronism with a subscanning synchronizing signal. CONSTITUTION:A CPU 10 prior to the read of an original picture sets the period of a printer synchronizing signal sent from a printer 20 and a timing signal generating circuit 4 generates a line synchronizing signal in a reader from the printer synchronizing signal. The CPU 10 standardizes an output signal of an A/D converter 3 by varying the setting value to a reference voltage generating circuit 13 in order to normalize the read density. Then the CCD 1 and the motor 12 are driven in synchronism with the printer synchronizing signal inputted from a picture recorder to vary a reference voltage for the A/D converter 3 and a gamma conversion data. Thus, the original picture is read and the picture data is sent completely in synchronism with any of plural picture recorders with different print speeds.
