Inventor: MORI AKINOBU
IPC: B29K105/10
Filed: 1989-03-30
Abstract: PURPOSE:To prevent crack from developing due to the hardening of matrix resin and suppress the lowering of the strength of a composite material and the ununiformization of its physical properties by a method wherein filling material made of inorganic powder is dispersed in a three-dimensional woven fabric in a mold by vibrating the mold before the impregnation of resin and, after that, the impregnation of the matrix resin in the three-dimensional woven fabric is performed for molding. CONSTITUTION:When the molding of a three-dimensional woven fabric reinforced composite material is performed, a three-dimensional woven fabric 3 is charged in a mold and filling material 5 is introduced from a filling material container 4 through a passage 6 in the mold under the condition that the mold 1 is vibrated by means of an exciting device 2 before the impregnation of matrix resin so as to disperse the filling material in the three-dimensional woven fabric. After the dispersion of proper amount of the filling material in the woven fabric, the matrix resin 9 is run from a resin tank 8 through a flow path 10 in the mold so as to impregnate the three-dimensional fabric 3 with the matrix resin and finally the resin 9 is hardened in order to complete the molding of composite material. The dispersion of the filling material can be accelerated by vacuumizing the mold by means of a vacuum pump. In this case, the degree of vacuum depends upon the particle diameter, size of woven fabric and the like and the vacuum adopted as the first standard is about 10<-3>Torr to be used as reference value.

Title: Phase comparator for synchronous loop
Inventor: NAGAYASU MASATOSHI
IPC: H03K5/26
Filed: 1988-03-31
Abstract: PURPOSE:To avoid delivery of the wrong comparison output even in case the timing information on a data train has omission by inverting the output of an exclusive OR gate using the mutual outputs of two flip-flops as inputs via the pulse of a synchronous loop for output of a control pulse. CONSTITUTION:The output of an exclusive OR gate 3 is kept at H for a period covering the rise shift of an input data train through the rise of the internal timing. Then the output of the gate 3 is latched by a flip-flop 4 with the fall shift set at the middle of the rise shift of the internal timing for decision of a signal that advances or delays the phase to a voltage control oscillator 12. Thus a pulse is transmitted so that the phase is controlled only when the rise of the data train is applied to a flip-flop 1. As a result, the wrong frequency control is applied to a synchronous loop despite the omission of the timing information on the input data train.

Abstract: PURPOSE:To strengthen a container made of FRP for storing super low temp. refrigerant such as liquid helium or the like, by fabricating its cylindrical part and end plate  part separately and limiting the difference between axial thermal expansion coefficients of both members on the coupled portion within a specific value. CONSTITUTION:A cylindrical part 1 and an end plate part 2 are made separately. From the view points of formability and physical property, the cylindrical part 1 is made of  FRP made by winding one directional long fiber, and the end plate part 2 is made of  FRP made by laminating such a material as obtained by properly arranging to a textile  like product or to one directional long fiber. In order to decrease the difference between thermal expansion coefficients in a laminated surface and a laminated direction,  a cylindrical portion continuing to an end plate is formed on the end plate part 2, and the cylindrical part 1 and the cylindrical portion of the end plate part 2 are coupled  and fitted to each other to arrange the cylindrical portion to the outside and the  cylindrical part 1 to the inside. Then, the axial tensile shearing stress is restrained by making the difference between axial thermal expansion coefficients of the inner cylinder side and the outer cylinder side within 20X10<-6>/ deg.C. With regard to the radial  tensile force, the above condition can be satisfied, if the thermal expansion coefficient  of the outer cylinder side is larger, even if it is made of a material with different  properties.

IPC: B21B21/04
Filed: 1986-04-10
Abstract: PURPOSE:To decrease unbalanced external force as far as possible and to make stable operation with a small balancing device by balancing the inertial force of a rolling mill which converts rotating motion to reciprocating motion by springs and selectively controlling spring constants by rotating speeds. CONSTITUTION:The rotation of a crank arm 3 by a motor 1 is transmitted by a connecting rod 5 to a stand 8 of a Pilger mill 7 so that the stand moves back and forth. The stand is supported by the springs 10 having the spring constant corresponding to the max. rotating speed in this case to absorb the inertial force. The changed rotating speed of the arm 3 is detected by a tachogenerator and rotating angle detector 11 and the spring combination conforming to the calculated 12 correction spring constant is selected by a spring constant varying device 13 and is assembled to the springs 10. The above- mentioned device 13 is operated to select the spring set having spring constants K1-K4 as desired by selectively pushing cylinders 21, 22. The unbalanced external force is minimized by the above-mentioned technique and the inertia force of various reciprocating force is absorbed by the smallest balancing device, by which the stable operation of the rolling mill is executed.

Filed: 1982-05-14
Abstract: PURPOSE:To prevent an electrostatic latent image from deterioration and to obtain a stable and fine picture by separating a cleaning brush from the surface of a photoreceptor while contacting the brush with a flicker cover and stopping the rotation of the brush during the copy of plural sheets by one exposure. CONSTITUTION:A supporting arm 7 supporting the cleaning brush 6 pivotally is mounted on the frame of the body through a supporting shaft 13 so as to be freely rotable around the shaft 13. The flicker cover 17 is arranged on a position slightly touching the leading end part of the brush 6 contacted with the surface of the photoreceptor 1. When a solenoid 14 and a brush motor 12 are deenergized at a moment an electrostatic latent image reachs closely to a cleaning part after transferring the 1st picture, the brush 6 is separated from the surface of the photoreceptor 1 by the energizing force of a spring 16 to stop the rotation. Consequently the electrostatically charged potential of the brush 6 is suddenly reduced, so that the electrostatic latent image is almost prevented from deterioration and plural fine pictures are obtained.
