Title: Production of protein sustained release microsphere
Inventor: UCHIDA TAKAHIRO
IPC: A61K39/00
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To realize a method for obtaining the subject microspheres having an excellent sustained release property by adding a specific protecting agent to the solution of a protein used as a physiologically active substance or an antigen used for vaccines, and further using a polymer capable of being orally administered or injected. SOLUTION: This method for producing the protein sustained release microspheres comprises preliminarily adding gelatin to a protein-containing solution, mixing and emulsifying the mixture with an organic solvent containing a biodegradable polymer, reemulsifying the emulsion in an aqueous phase containing a dispersant, and subsequently recovering the produced microspheres. The gelatin is desirably added to the protein solution in a concentration of >=4%. The addition of the gelatin to the preparation of the protein-containing microspheres in this method enables to encapsule the protein in the micropheres without denaturalizing or inactivating the protein with the organic solvent. When the microspheres are prepared at a freezing temperature, the protecting effect on the protein from the organic solvent is further improved.  In addition to the above method, a method wherein the gelatin is added to the dispersant-containing aqueous phase (outer aqueous phase) at room temperature may be performed.

Filed: 1989-12-25
Abstract: PURPOSE:To enable highly-precise inspection of a soldered state of an electronic component by providing a slit light applying element applying first and second slit lights, an image pickup element, a reference data storing element and a determining element. CONSTITUTION:When slit laser lights 7a and 7b are applied from a slit light applying element 6 to a soldered part of an electronic component mounted on a printed circuit board 9, a slit pattern by the two lights is formed on the soldered part. The slit pattern is separated in two according to the shape or the like of the soldered part, and separated widths and lengths correspond to a soldered state. The data on the slit pattern formed on the soldered part of which the soldered state is proper are stored in a central arithmetic processing element 4 which is a reference data storing element. The image of the slit pattern formed on the soldered part being an object of inspection is picked up by an image pickup camera 1 and led to the arithmetic processing element 4 being a determining element. The soldered state is determined to be proper when the result of comparison between the data detected on the basis of the picked-up image data and the data read out of the arithmetic processing element 4 is within an allowable range.

Filed: 1990-11-30
Abstract: PURPOSE:To always form a smooth layer of uniform film thickness by providing elastic bodies between a liquid crystal substrate and a table and between a pressing substrate and a pressing body. CONSTITUTION:An elastic sheet 40 is mounted on a table 3. When gas is supplied in a pressing tank 2, a rubber sheet 8 expands to press a pressing substrate 21, by which a smoothing resin 22 firmly adheres to the pressing substrate 21. After adhering, fine particles 50 on the table 3 or on a color filter substrate 30 are embedded in the elastic sheet 40, while fine particles 50 on the pressing substrate 21 are embedded in the rubber sheet 8. Thus, the color filter substrate 30 and pressing substrate 21 are free from deformation. Then after the smoothing resin 22 is cured with irradiation of UV ray, the pressing substrate 21 is released to form a smooth layer on the color filter substrate 30. Thereby, even fine particles 50 exist between the color filter substrate 30 and the table 3, a smooth resin layer can be formed.

Inventor: HATORI KAZUYUKI
IPC: G03G15/20
Filed: 1989-12-28
Abstract: PURPOSE:To allow the exact detection of a service life and to prevent the erroneous recognition of an old fixing device as a brand new fixing device by forcibly shorting a circuit to blow a fuse, then detecting the life of the heat fixing device in accordance with the detecting voltage from a detecting circuit. CONSTITUTION:For example, a temp. detecting element TH for life detection 10 and a fixed resistor R 1 are connected in series to constitute the detecting circuit. The fuse FU is connected in parallel to at least one resistance element R 2 constituting the detecting circuit. A synthesized resistor for voltage dividing is thereby formed of the fuse FU and the resistance elements R 1, R 2. The detecting voltage at the point of the time when the fuse FU is connected in parallel, therefore, approximates to the voltage of a circuit 30 for control or 0v. The presence or absence of the fuse FU can be decided easily by impressing the circuit voltage to the detecting circuit. The circuit is forcibly shorted if there is the fuse FU. The exact life detection is executed in this way in accordance with the detecting voltage from the detecting circuit and the erroneous recognition of the old fixing device as the brand new fixing device is prevented.
