Title: Aging method of cathode-ray tube
Inventor: IMANISHI WATARU
IPC: H01J9/44
Filed: 1982-03-03
Abstract: PURPOSE:To check the functional deterioration of cathode powder and drop the gas pressure inside a gaseous body as well as to secure satisfactory emission characteristics, by impressing a high voltage on an anode and letting a beam current flow through a phosphor screen, while adding an alternating field from the outside of either a neck part or a funnel part. CONSTITUTION:A positive voltage of 10-30kV is impressed on an anode 17 to which an alternating field is arranged to be imparted by a coil 26 installed close to a funnel part 3 at the outside of a neck part 4. Therefore, when any voltage like this is impressed, the beam current 25 accelerated and deflected by the voltage of 10-30kV runs a long distance up to a phosphor screen 6 from a cathode 13 and thereby almost all of ionization and decomposition are produced inside the funnel part 3, so that a phenomenon of carbon sticking on cathode powder 21 causing deterioration in a cathod emission can be greatly decreased. With this, satisfactory emission characteristics can be secured.

Title: Injection molding machine
Inventor: KANDA KATSUTOSHI
IPC: B29C45/40
Filed: 1988-02-17
Abstract: PURPOSE:To shorten the molding cycle time of a product by enhancing followability and increasing the operation speed of a movable part, by driving the fluid actuator of a product recovery apparatus, by the fluid cylinder stretched between a fixed part and the movable part. CONSTITUTION:A movable part 3 is alternately reciprocated in the directions shown by arrows Y1, Y2 and a product 5 is subjected to injection molding at each time when a mold 1 is clamped. After the molding of the product 5, when movable part 3 is moved in the direction shown by the arrow Y2, the piston rod 15a of the second hydraulic cylinder 5 is moved to the right and operation oil is discharged from the first port 15c to be supplied to the first port 14c of the first hydraulic cylinder 14 through a pipeline 15 to drive the first hydraulic cylinder 14. Since the process volume of the first hydraulic cylinder 14 is smaller than that of the second hydraulic cylinder 15, the first hydraulic cylinder 14 is subjected to full stroke operation before the spaced- apart operation of the movable part 3 is completed and a bucket 13 is also moved to a receiving position before the spaced-apart operation of the movable part 13 is completed and the product 5 is demolded with the completion of the spaced-apart operation of the movable part 3 to be recovered in the bucket 13.

Title: Method for generating high density dot character
Inventor: NISHIKAWA KAZUNARI
IPC: G06K15/10
Filed: 1988-02-17
Abstract: PURPOSE:To reduce the data quantity of an encoded character, by decomposing a character into unit groups becoming one stroke per one raster to effectively utilize the repeated data of the same stroke and compressing the data quantity of the encoded character stored in a memory device. CONSTITUTION:For example, five elements A1-A5 are contained in a raster of A-A' and three elements B1-B3 are contained in a raster of B-B'. In a high quality dot character used in printing, A1 and B1 as well as A5 and B3 are different in a contained raster number but same in the code of a stroke element. In a kanji wherein vertical and horizontal lines are frequently used, this case is generated extremely numerously. Therefore, when the stroke element of a characters are respectively decomposed into block units continuous only in a raster direction, the repeating number of times of the same element are indicated in such a case that the same element is repeated in the raster direction to remove many elements. By this method, the data of a character can be compressed to a large extent.

Title: Image processing unit and its method
Inventor: KOBAYASHI NORIYUKI
IPC: H04N1/46
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To attain effective utilization of a memory area without excessive data storage by storing color image data consisting of a plurality of color components while minimizing a quantity of the image data of color components discriminated not valid. SOLUTION: A differential adder 23 accumulates a difference between a value of a pixel and that of adjacent pixels for each color component of received image data, and a comparator 24 compares the accumulated value with a prescribed threshold value. When the accumulated value exceeds the threshold value, a filp-flop 25 outputs a storage enable signal at an L level to instruct storage of image data of the color component after compression. On the other hand, when the accumulated value is less than the threshold value, the slip-slop 25 outputs a storage enable signal at an H level to instruct storage of only a mean value of image data of the color component calculated by a mean value calculation section 26.
