Title: Cover eccentricity measurement of long-sized body
Inventor: YAMAMOTO YOSHIO
IPC: G01B11/00
Filed: 1985-02-27
Abstract: PURPOSE:To enable automatic measurement of the cover eccentricity of a long- sized body based on the node length ratio, by arranging a light irradiation system and light receiving screens to sandwiching a long-sized object after covered. CONSTITUTION:Covering dies 2, light irradiators 5 and 7, light receiving screens 6 and 8, CCD cameras 9 and 10, a microcomputer (MC) 11 and the light are arranged. When a long-sized object 1 running vertically on the Y axis passes through the dies 2, a cover layer is formed on the circumference thereof. As the long-sized object 1 reaches light irradiation areas of the irradiators 5 and 7, an image of the long-sized object 1 is projected on the respective screens 6 and 8 by the scattered light of the irradiation light and taken with the cameras 9 and 10, which then, send given information to the MC 11 which previously obtained the adjusting value of the dies as function of the node length ratio alone not depending on the outer diameter of the cover and eccentric direction adjusts the position of the dies directly from the node length ratio obtained from the cameras 9 and 10 using this function. Thus, the MC 11 can determine the eccentricity of the cover by computing information signal.

Abstract: PURPOSE:To obtain a particulate polymer by feeding, in a specific atmosphere, a polymer solution in an organic solvent and a polymer additive to a granulation zone containing polymer particles and evaporating the solvent while keeping the solution and additive in contact with the particles. CONSTITUTION:At least one polymer selected from among a polycarbonate, a polyacrylate, a polyester-carbonate, etc., is dissolved in an organic solvent, e.g. methylene chloride, to prepare an about 3-60wt.% polymer solution. A small amount of polymer particles are introduced into a granulation tank equipped with a stirrer having double helical blades, and this tank is regulated to be free from water vapor and have a given temp. and an inner pressure of -500mmHg to 10kg/cm<2> in order for the solvent to evaporate. The polymer solution and a solution in heptane of a polymer additive, e.g., an antioxidant, are then intermittently fed to the tank with stirring. After a residence time of about 0.1-10hr for solvent evaporation, the resulting polymer particles are taken out, and transferred to a dryer into which an inert gas is blown. Thus, a dry particulate polymer is obtained.

Filed: 1978-04-03
Abstract: PURPOSE: To increase the drain saturation current with a high dielectric strength by providing the low-density gate region adjacently to the gate electrode.  
     CONSTITUTION: The n-epitaxial thin layer of Si is formed selectively on sapphire 1 to obtain n +  layer 3 and 4 plus p +  layer 5.

In such constitution, low- density extension gate 10 is increased although channel 8 freatures a high density, and the ion injection amount is selected at gate 10. As a result, the dielectric strength can be enhanced greatly between the drain and the gate, and at the same time the ion resistance can be lowered.

Abstract: PROBLEM TO BE SOLVED: To secure close adhesion of a solid-state laser device and an O ring and at the same time a cooling property in the vicinity of a light projecting face. SOLUTION: The light projecting faces f3 of the front end part and rear end part of a solid-state laser medium are so formed as to intersect the upper and lower surfaces, f1 and f2 , of the laser medium at a right angle, and an O ring 27 is arranged as close to the light projecting face f3 as possible, so that a part of the laser medium projecting from the O ring can be much lessened in length than a conventional one where the light projecting face f3 is tilted. Cooling water can be surely fed near the light projecting faces f3 of the laser medium keeping the O ring in a fixed posture, so that laser beams can be lessened in distortion as much as possible.  The crosswise edges of the laser medium are formed like an arc in a front view, the O ring 27 is more enhanced in adhesion to the solid-state laser medium as compared with a case where an O ring 27 is directly mounted on an angular oscillating member, and the O ring 27 hardly suffers local damage.

Title: Low strain current source
Inventor: WAKIMOTO TSUTOMU
IPC: H02J1/02
Filed: 1989-02-21
Abstract: PURPOSE:To improve higher harmonic strain and operation speed by generating compensatory current to supply to an output terminal of a voltage source in the same amount as in the changed portion of collector current or drain current of a transistor whose collector terminal or drain terminal is connected to the output terminal in all the biased conditions. CONSTITUTION:A voltage variation at an output terminal 11 of current sources 3, 16 and 17 is detected and the compensatory current is generated to supply to the output terminal 11 in all the biased conditions which is equal in amount to the current flowing to a junction capacitance between the base and collector or between the gate and drain of transistors 1, 10 and 14 connected to the output terminal. Consequently, the junction capacitance value between the base and collector or between the gate and drain of the transistors 1, 10 and 14 connected to the output terminal 11 of current sources 3, 16 and 17 becomes zero in terms of equivalence. The higher harmonic strain can thereby be reduced and the operation speed improved accordingly.
