Title: Carbon fiber for reinforcing highly heat-resistant resin and its resin composition
Inventor: KATAOKA TOSHIYUKI
IPC: D06M15/37
Filed: 1995-04-12
Abstract: PURPOSE: To obtain a resin composition, comprising a carbon fiber for reinforcing a highly heat-resistant resin having the surface coated with an aromatic polyimide and/or an aromatic polyamic acid-based resin and the highly heat- resistant resin and suitable for moldings, excellent in mechanical properties and heat and chemical resistances. CONSTITUTION: This carbon fiber for reinforcing a highly heat-resistant resin is obtained by immersing a carbon fiber in a treating liquid prepared by dissolving an aromatic polyimide resin of formulas I and II (X in both the formulas I and II is formula III or IV; Y is one or more groups selected from formulas V, VI, etc.; R1 to R7 are each a 1-20C alkyl, a halogenated alkyl, H or a halogen) and/or an aromatic polyamic acid which is its precursor in N-methyl-2- pyrrolidone and drying the resultant fiber. The surface of the resultant fiber is coated with the resin. The highly heat-resistant resin composition is obtained by blending 5-100 pts.wt. resultant carbon fiber with 100 pts.wt. highly heat- resistant resin such as a polyether ether ketone having >=250 deg.C melting point and >=100 deg.C glass transition point.  The resultant resin composition is molded into a prescribed shape to a afford electronic or automotive parts.

Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To improve single crystallization ratio by imparting a specific compressive stress to a transparent layer of a crucible composed of the transparent layer on the inner surface side and an opaque layer, which is on the outer periphery of the transparent layer and in which many bubbles are present, to suppress the incorporation of the bubbles into a silicon melt. SOLUTION: The crucible is formed from the 2 layers and has the transparent layer 3 on the inner surface side 2 and the opaque layer, which has many bubbles, for example about 8000-12000/cm<3> bubbles having 1.0-250 μm particle diameter and 32-38 MPa breaking strength, on the outer periphery of the transparent layer 2. The compressive stress 30-50% of the rupture strength of the opaque layer 5 is imparted to the transparent layer 2. The thickness of the transparent layer 3 is controlled to >=1 mm and >=60% of that of the opaque layer 5. As a result, micro-bubbles existing in the transparent layer 3 expands to large bubbles and the incorporation of the bubbles to a molten silicon with the dissolution of the transparent layer 3 of the inner surface side 2 is suppressed.

Title: Lateral shifting mechanism of shifting device for communication apparatus
Inventor: SOEDA HIDETSUGU
IPC: H04Q1/02
Filed: 1979-07-13
Abstract: PURPOSE: To avoid the skidding of the rollers during their running as well as ensure an in stantaneous halt when the brake is applied for the mechanism in which the guide rail is held between the running roller and the driving roller to give a lateral shift to the guide rail, by securing a constant push-up force for the driving rollers.  
     CONSTITUTION: Vertical rod 46 is pressed down by operating operation component 48, and thus central seesaw component 34 turns clockwise to give compression to elastic components 39 and 45. With this compression, left and right seesaw components 20 and 22 turn clockwise to make left and right push-up rollers 24 and 26 touch the bottom surfaces of left and right box-shaped substances 9 and 11. As a result, substances 9 and 11 go up. Furthermore, driving rollers 13 and 15 touch the bottom surface of guide rail 2 with extension of the push-down stroke of rod 46, and thus the bottom plate of rail 2 is held between running roller 3 and driving rollers 13, 15. In such way, rollers 13 and 15 are pushed up via elastic components 36 and 45, and as a result rollers 13 and 15 can hold the guide rail between with nearly an equal push-up force although the guide rail 2 may tilt to avoid the deviation of force.
