Abstract: PURPOSE:To realize sharp halftone printing by deriving image information with first print density or that with second print density selectively based on a control signal sent synchronizing with the image information with the first print density. CONSTITUTION:A converter 17 inputs black picture element number signals of four picture elements of image data with 300dpi, and outputs it after converting to the image data of 16 picture elements with 1200dpi.

Also, when only one piece of image data shows a black picture element, the image data with 1200dpi of 16 picture elements in which one black picture element is repeated at every fourth picture element is outputted. Furthermore, when only two pieces of data show the black picture elements, the image data of 16 picture elements with 1200dpi in which the white picture element and the black picture element are repeated at every third picture element is outputted. Also, when one piece of data shows the white picture element, the image data with 1200dpi of 16 picture elements in which one white picture element is repeated at every fourth picture element is outputted. When all image data show the black picture elements, the image data go to the black picture elements.

IPC: C07C239/00
Filed: 1979-04-06
Abstract: NEW MATERIAL:Basic L-amino acid.L-malic acid salt crystal.  
     EXAMPLE: Neutral L-ornithine.L-malate dihydrate crystal.  
     USE: Medicine and nutrition enriching additive. Especially useful as an improved amino acid transfusion composition. The defects of a free basic L-amino acid or a besic L-amino acid hydrochloside, such as moisture absorption, bitter taste, acidosis caused by transfusion, etc. are improved by converting the basic L-amino acid into its L-malate.  
     PROCESS: L-Malic acid is dissolved in an aqueous solvent containing a free basic L-amino acid (e.g. L-lysine, L-ornithine, L-arginine, etc.) to adjust the pH of the solution within 6.5W7.5, and a hydrophilic organic solvent (e.g. methanol, acetone, etc.) is added to thereto, to separate out the desired crystal. The crystallization can be accelerated by adding a seed crystal. The molor ratio of the basic L-amino acid to L-malic acid is pref. 2 to 1.

Title: Code converter
Inventor: HIRANO YASUHIRO
IPC: G11B20/14
Filed: 1983-03-16
Abstract: PURPOSE:To produce a code series having a good DC balance by having correspondence between a code and two codes of (n+1) bits to reduce the difference between the numbers 1 and 0 in the case of conversion between (n) and (n+1) bits. CONSTITUTION:An input signal is converted into a parallel signal of (n) bits by a serial/parallel converting circuit 1 and then supplied to an n/n+1 converting circuit 2. At the same time a SIGMA1-SIGMA0 deciding circuit 4 supplies 1 and 0 signals to the circuit 2 when the number of 1 is larger than the number of 0 and vice versa respectively. The output of the circuit 2 is equal to a signal of (n+1) bits and produces one of two types of codes having a larger number of 0 codes when the 1 has a larger number and the code having a larger number of 1 when the 0 has a larger number respectively. These codes are converted into the series data by a parallel-serial converting circuit 3. Thus it is possible to produce a code series having a good DC balance.

Title: Cultured cancer tissue and its production
Inventor: KUBOTA YAMATO
IPC: C12Q1/04
Filed: 1991-02-16
Abstract: PURPOSE:To produce a cultured cancer tissue capable of sensitively measuring the effect of an anticancer agent in chemotherapy or radiotherapy, thermotherapy, etc., in physiotherapy on the cancer tissue in the living body in vitro by allowing cancer cells and normal cells to coexist and giving a duct structure to the cancer tissue. CONSTITUTION:Normal cells are cultured on a culture medium containing a temperature-sensitive polymer at a temperature of >=LCST so as to cover the surface of the culture medium with the normal cells. Thereby, a normal cell sheet is formed and cancer cells are inoculated and bonded to the normal cell sheet. The temperature is subsequently lowered to <=LCST and the normal cell sheet containing the cancer cells bonded thereto is released from the surface of the culture medium and allowed to float in the culture solution. This floating cell sheet is cultured on a cell-nonadhesive culture medium, thus producing the objective cultured cancer tissue. LCST is preferably 0 to 80 deg.C, further preferably 10 to 45 deg.C.

Title: Differential pressure converter
Inventor: HAYASHI TADAHIRO
IPC: G01L13/00
Filed: 1989-02-22
Abstract: PURPOSE:To completely prevent fast surge pressures from reaching a pressure sensing element to break the pressure sensing element by providing a center diaphragm on the center part of the through hole of a main body block and separating the through holes into a high-pressure side and a low-pressure side. CONSTITUTION:When the fast surge pressures Pa and Pb which exceed the upper limit of the detection range of the pressure sensing element 62 are applied to pressure receiving diaphragms 53 and 54, the surge pressures Pa and Pb are received by the diaphragms 53 and 54 and expected to be transmitted to the element 62. The surge pressures Pa and Pb, however, are attenuated because there are contractions of area 59b and 60b formed of gaps between bellows shafts 59 and 60 and the through hole 52 between the diaphragms 53 and 54 and lead holes 65 and 66 to the element 62. At this time, the bellows 57 and 58 receive the forces and are displaced to approach the center diaphragm 51, which is also displaced to a low-pressure side. At this time, the contractions of area 59b and 60b increase in length and also increase in resistance. The surge pressures Pa and Pb are attenuated speedily, so the surge pressures are prevented from reaching the element 62 before the diaphragms are seated on backup plates 67 and 68.

Abstract: PURPOSE: To certainly seal a tubular packaging material in which an article is housed by extending a shield from a stripper bar to arrange the outer surface thereof so as to leave an interval from a shaft by an almost constant radius in a radial direction and providing a stripper member almost coinciding with the outer surface in shape to the inner surface of the shield. CONSTITUTION: A bag shield 30 is provided with an arcuate outer surface 31 having an almost constant radius with respect to a shaft 32 around which a lever 26 revolves. A recessed surface 32 almost coincides with a surface 31 in shape. Since the surface 31 has a radius extending from the shaft 32, a stripper bar 17 can be engaged with a bag member 15 at a position nearer to a sealing jaw 16. By forming the gag shield 30 into this shape, a bag can take a shape maximizing a utilizable vol. for an article but, in spite of this, it is ensured that the sealing jaw 16 becomes a length sufficient to be properly engaged with a bag member 15.

Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To permit high speed operation of a sense amplifier when amplification amplitude between pairs of data line is reduced in order to cope with low power consumption and minuteness. SOLUTION: A potential between a source and a gate of a MOSFET included in a sense amplifier is made large by deviating a pre-charge potential VDP of a pair of data line from a half pre-charge level and MOSFETs Q1-Q4 of the sense amplifier are made easy to operate. Thereby, the sense amplifier can be operated at high speed even if amplitude between pairs of data line is reduced.
