Title: Japanese syllabary-chinese character conversion processing system
Inventor: HAYASHI HIROKAWA
IPC: G06F17/28
Filed: 1982-09-16
Abstract: PURPOSE:To add KANAs (giving the pronunciation of Chinese character) after conversion through simple operation, by displaying the reading of every displayed KANJI candidate of conversion in response to an operator's indication. CONSTITUTION:A word extraction part 3 receives a KANA character string extracted by an input preprocessing part 2 through a conversion control part 7 and extracts candidates of conversion corresponding to the character string by referring to a conversion dictionary to store them in a candidate word storage part temporarily. When an operator operates a conversion key, the extraction part 3 extracts the candidates of conversion, which are displayed 6 by an output control part 5. In this case, reading indexes of word candidates obtained from the conversion dictionary and corresponding KANJI characters are both stored in the candidate word storage part. When sending data on the candidates to the control part 5, a control part 7 checks whether a reading display mode is set or not firstly and when so, the data in the candidate word storage part is read out and parenthesized for every KANJI candidate of conversion on the display 6.

Title: Changing-over device of mold clamping force in motorized injection molding machine
Inventor: YAMAZAKI YOSHIHIKO
IPC: B22D17/26
Filed: 1984-07-30
Abstract: PURPOSE:To efficiently increase the speed of opening and closing of a mold and the mold clamping force by a method wherein a device, which changes the ratio of gears meshing with each other by properly changing-over two clutches and the large and the small gears, is added to the changing-over device of mold clamping force. CONSTITUTION:A small gear 32 is put into free state by cutting off the electric current to be supplied to the electromagnetic clutch 33 of a driving shaft 24. On the other hand, a transmission shaft 25 is connected with a mold clamping output shaft 28 through a large gear 30 by exciting the electromagnetic clutch 29 of the transmission shaft 25. Because a transmission shaft side gear 27 is smaller than a driving shaft side gear 26, the rotation of the transmission shaft 25 becomes higher than that of the driving shaft, resulting in making the speed of opening and closing of a mold quicker. When the clamping of the mold is intended, the connection of the transmission shaft 25 with the mold clamping output shaft 28 is disengaged by releasing the electromagnetic clutch 29 of the transmission shaft 25. In addition, the small gear 32 is fixed to the driving shaft 24 by exciting the electromagnetic clutch 33 of the driving shaft 24. Because the gear 30 is larger than the driving shaft side gear 32, the turning force of the mold clamping output shaft 28 becomes larger, resulting in making the mold clamping force larger.

-35
, and an adhesive is coated thereon and is dried, when inserting the inner blank pipe into a steel pipe and reducing the diameter of the steel pipe to adhere and fix the two pipes to each other. CONSTITUTION:In a method for producing a lined steel pipe wherein a blank pipe made of a synthetic resin is inserted into a steel pipe and the diameter of the steel pipe is reduced by drawing or other means to integrally adhere the two pipes to each other, the outside surface of the resin-made blank pipe constituting an inner pipe is preliminarily roughened to a roughness of 6
-35
, then an adhesive is coated thereon and is dried. By such a pretreatment, it is possible to prevent the blocking phenomenon of the adhesive coated on the surface of the blank pipe, which phenomenon would otherwise be generated at the time of inserting the blank pipe made of a synthetic resin into the steel pipe.

Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To improve a DMA transfer speed for image information from a DRAM used as a page memory to an image formation means. SOLUTION: In response to one DMA request from a plotter part 2, a DMA control part 10 DMA transfers to the plotter part 2 an image information in units of a plurality of words continuously with the same row address from a page memory 8 as a DRAM. Prior to the transfer, the image information of one page on the page memory 8 is sequentially converted in longitudinal and lateral directions in units of squares of a plurality of words by the DMA control part 10 and a longitudinal lateral conversion part 9. In a state where the image information after the conversion is rotated by 90 deg. or 270 deg. by the DMA control part 10, an address for transferring the information to the plotter part 2 can be generated.  Also, the number of words can be set by the plotter part 2 with a finer unit than that of the number of words of the image information DMA transferred continuously by the DMA control part 10 and the image information of the number of words can be masked from a leading end of a line.

IPC: B23P25/00
Filed: 1977-12-29
Abstract: PURPOSE:To simultaneously process a plurality of thin plates without hurting the surfaces thereof. CONSTITUTION:A plurality of thin square plates 1 to be procssed are first laminated via layers of a bonding agent 2. After the bonding agent 2 has been hardened, a large lamination 4 is obtained, which is then divided into several parts 5 of a predetermined dimensions. A lamination 5 thus obtained is then pasted on a special jig 3 with the same bonding agent 2, or directly chucked by the jig 3. The outer surface of the lamination is then subjected as it is to a grinding treatment. After the grinding treatment has been completed, the bonding agent 2 is removed to separate the thin plates 1 from one another to obtain a plurality of processed thin plates of a predetermined shape. According to this invention, thin plates are not hurt during a grinding operation since the outer surfaces thereof are protected by a bonding agent. In addition, the grinding operation can be conducted easily and at a high accuracy since the material to be ground is in an integrally laminated state.
