Title: Artificial organ composed of atypical col- lagen tube for suturing hollow organ
Inventor: BENIAMIINO PARUMIEERI
IPC: A61B17/11
Filed: 1990-06-28
Abstract: PURPOSE: To make it possible to have one end of the sutured section face the other end completely, as well as to facilitate the suture operation by making a radiated semi-transparent tubular form with one end of frusto-conical shape, at the mid-point of which a sword-guard-shaped peripheral edge is provided. CONSTITUTION: This artificial organ is the tubular body with a cylindrical inner wall 1 and a frusto-conical-shaped (at the tips) outer wall 2, at the mid- point of which a sword-guard-shaped peripheral edge 3 is provided. Either a radiated semi-transparent wire is inserted or barium sulfate is mixed into the material of this organ, in order to give a radiated semi-transparency to this material. Since the ends are formed to a frusto-conical shape, this allows the organ to be inserted easily into an organic cavity of the subjected organic end, while collagen fulfills its function of uniting the sutured section, as well as the sword-guard-shaped peripheral edge fits further well to the section of suturing the organ.

Title: Ink jet recorder
Inventor: DANZUKA TOSHIMITSU
IPC: B41J2/175
Filed: 1991-06-13
Abstract: PURPOSE:To eliminate inflection points in gradation characteristics to remove artifical profiles by a method wherein ink is formed by modulating the densities of ink of a plurality of kinds in accordance with the recording characteristics of each recording means. CONSTITUTION:As an amount of thin black ink in a thin ink tank 11 is reduced, a float 13 is lowered, and a light emitting from a lamp light source 15 to a photodiode 16 is not interrupted. When detecting this emitted light, the photodiode 16 transmits actuation signals to a transparent ink pump 14 and a dense ink pump 14. A control circuit stores actuating times for the transparent and dense ink pumps 14 in accordance with the recording characteristics of a thin recording head 9 and a dense recording head 9, e.g., OD values at the time of solid recording. The pumps 14 are respectively actuated for a predetermined time. By forming thin black ink from transparent ink and dense black ink, the density of thin black ink to be supplied to the thin recording head 9 is modulated to realize ideal gradation characteristics. Therefore, the occurrence of inflection points in gradation characteristics is eliminated, and a high-quality image can be obtained.
