Title: Cutter for adhesive sheet
Inventor: SUZUKI ISAMU
IPC: B26D1/20
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To prevent paste of an adhesive sheet from sticking to a fixed blade and rotary blade in the case of cutting the adhesive sheet, so as to eliminate necessity for cleaning these blades. SOLUTION: In the case of cutting an adhesive sheet 3 set onto a fixed blade 1 by a rotary blade 2, a groove 4 is formed in a location of the fixed blade 1 corresponding to an edge point 2b in a part 2a of the rotary blade 2 lapped deepest in the fixed blade 1. In this way, when the adhesive sheet 3 is cut, even when its cut surface is positioned in the part 2a deepest lapped with the edge point 2b, since the groove 4 is formed in the fixed blade 1 corresponding to this part, paste of the cut section of the adhesive sheet 3 is prevented from sticking to the fixed blade 1. By providing felt 5 impregnated with oil, the paste can be prevented from also sticking to this slope, since silicon oil is stuck to a tip end part slope 2c of the rotary blade 2 by the felt 5.

Title: Measuring device for paramagnetic substance component
Inventor: YOHAN OTSUTEN
IPC: G01N27/74
Filed: 1994-02-28
Abstract: PURPOSE: To prevent adverse influence upon an AC voltage signal magnetically induced by a constitution indicating that the compensation voltage formed in a measuring magnetic field coil has the same amplitude as a basic signal excited by the difference of the thickness of a material between a cuvette chamber and a reference chamber but is the process of a reverse phase to the basic signal. CONSTITUTION: A 90-degree phase difference is generated toward a magnetic flux for a voltage induced in a measuring magnetic field coil, a voltage is formed by means of the time variation of the magnetic flux of an inductive loop, and this voltage is shifted by 90 phase. Thus, a reverse phase is entirely constituted. A cuvette 2 has a rotary-shaft symmetrical cutout port 8, and the cutout port 8 releases an end face 6 toward a magnetic disk 3. The internal space of the cutout a 8 charges a measured object with its regular magnetic characteristics, for example, oxygen. The basic signal is excited in a magnetic field coil 7 by two cutout parts 8 and a cuvette material therebetween passing along a core 5, alternately.  Thus, the substance characteristics of a cuvette arrangement structure is formed with the regular magnetic material so as to prevent adverse influence upon a magnetically induced AC voltage signal.

Title: Prolonged release pharmaceutical
Inventor: MIYATA KENJI
IPC: A61K47/00
Filed: 1984-02-22
Abstract: PURPOSE:An inexpensive prolonged release pharmaceutical, containing Plantago seeds containing a water-swellable mucilagions substance, and capable of forming a mucilaginous gel matrix and releasing a chemical component constantly at a givae ratio, and easily preparable. CONSTITUTION:A prolonged release pharmaceutical containing Plantago seeds of the genus Plantago of the family Plantaginacea. The amount of the Plantago seeds to be incorporated is 1-50%, preferably 10-30%. The Plantago seeds are well known as a purgative, but the action of forming mucilaginous gel matrix is novelly utilized to produce the aimed prolonged release pharmaceutical as a medicine. The gelation of the mucilaginous substance by hydration swells and expands the whole pharmaceutical and forms a matrix membrane. Thus, the release of the chemical component is controlled. The raw material Plantago seeds are more inexpensive than the raw material for the conventional brolonged release pharmaceutical without requiring special equipment nor step.
