Title: Method for chemically modifying protein
Inventor: DEIBITSUDO BONNAFUE
IPC: C07K1/113
Filed: 1992-03-19
Abstract: PURPOSE: To provide a method to chemically modify proteins in an aqueous or org. medium according to the modification parts so as to introduce various kinds of modifying groups by bringing a protein into contact with a reagent comprising a specified cyclohexene dicarboxylic acid anhydride deriv.  
     CONSTITUTION: Acetobromoglucose or the like is allowed to react with a malonaldehyde sodium salt to obtain an unsatd. aldehyde, which is then allowed to react with methylene triphenylphosphorane to obtain a diene expressed by formula I (R is a univalent org. group such as glucose). The diene is allowed to react with maleic acid anhydride by Diels-Alder addition processes to obtain a cyclohexene dicarboxylic acid anhydride deriv. expressed by formula II. Then the compd. is dissolved in a solvent such as tetrahydrofuran, and the soln. is added to 0.07 M phosphate buffer soln. of a protein (e.g. cow serum albumin) to react mutually. Thus, the protein is chemically modified by the reaction of the amino groups of the protein with the acid anhydride compd.

Title: Solenoid valve
Inventor: NAKAMURA TAKASHI
IPC: F16K31/10
Filed: 1984-05-10
Abstract: PURPOSE:To reduce the electric power consumption of the solenoid valve and simplify the structure of a solenoid coil by a method wherein the position of a plunger, moved by the conduction of the solenoid coil, is held mechanically. CONSTITUTION:When the coil is conducted at first under the closed condition of the valve, the plunger 11 is moved by being attracted to an attracting piece 6 side and the plunger is rotated by the slope 15 of a waveform groove 13 at that moment. The valve is fully opened under this condition and when the conduction of the coil is eliminated subsequently, the position B of a protuberance 12 is moved by the force of a spring 7 to a point C, however, the opening degree of the valve is fully maintained also under this condition. When the coil is conducted again, the position of the protuberance 12 is moved to another point D, thereafter, the position of the protuberance is moved to the point A by the force of the spring and the valve is closed when an electric source is intercepted.

Title: Image fiber and its manufacture
Inventor: MATSUDA HIROO
IPC: G02B6/04
Filed: 1985-05-02
Abstract: PURPOSE:To set a direction of an emitted surface image of an image fiber to an optional direction by giving a torsion in the longitudinal direction, in a state that a mutual position relation of each core in a section has been kept constant. CONSTITUTION:Many pieces of cores 4 are placed by keeping a prescribed mutual position relation through a clad 5, extending over the overall length of an image fiber, a sectional shape covered with a jacket 6 is kept, and also the core 4 has a structure which has been twisted at a prescribed pitch P in the longitudinal direction. Since the core 4 is twisted at the pitch P, an emitted image 9b takes the same direction at every pitch P, and an output of a desired direction of the emitted image can be obtained at an interval of the pitch P. Therefore, when the image fiber is cut by leaving an adjusting allowance at one pitch P from a prescribed length, a place where an incident image 9a of an observed object on the objective end face of the image fiber and the emitted image 9b on an eyepiece end face 7b of the image fiber always become the same direction in one part is obtained. In this way, the direction of the emitted image against the incident image can be adjusted very easily.

IPC: B41M5/41
Filed: 1985-05-02
Abstract: PURPOSE:To enable printing to be conducted on a recording paper having a low smoothness, by controlling the melting point and the softening point of a heat-fusible material comprising a binder or the like and applied to a base of a thermal transfer sheet, in the thickness direction of the material. CONSTITUTION:Two ink layers 2, 3 having different melting points are sequentially provided on the base 1 by sequential coating so that the melting point of the ink layer 2 in contact with the base is lower than the melting point of the upper ink layer 3 and is higher than the softening pint of the upper ink layer 3. In the process of thermal transfer recording by using a recording paper having a low smoothness, the thermal transfer sheet can be set into a condition wherein the ink layer 2' beneath a heating resistor 21 is melted and the ink layer 3' therebeneath is softened. By melting the ink layer 2', the adhesion of the base 1 and the ink layer 2' is weakened, and by softening the ink layer 3', an adhesive force is generated at the part where the ink layer 3' makes contact with the rough-surface paper 6, thereby forming a bridge of the ink layers 2', 3' at a non-contact part. Accordingly, the heated ink layers 2', 3' are transferred onto the paper 6.
