Title: Surface-modifying agent for carbon fiber
IPC: C08J5/06
Filed: 1992-03-24
Abstract: PURPOSE:To obtain the subject modifying agent effective in improving the adhesivity of carbon fiber to a matrix resin by forming a polyimide resin composed of a mixed diamine consisting of two specific kinds of primary diamines and an aromatic tetracarboxylic acid on the surface of a reinforcing carbon fiber. CONSTITUTION:A mixed diamine obtained by mixing a symmetric meta- substituted primary diamine of formula [X is O, SO2, S, C=O, CH2, C(CH3)2, C(CF3)2 or direct bond] with a symmetric aromatic para-substituted primary diamine at an equivalent ratio of (10-90):(90-10) is made to react with an aromatic tetracarboxylic acid dianhydride in nitrogen atmosphere to obtain a polyamic acid solution. A carbon fiber bundle is immersed in a liquid produced by diluting the above solution, dried with heat and heated in nitrogen atmosphere to convert the polyamic acid into polyimide and obtain a reinforcing carbon fiber having polyimide resin formed on the surface of carbon fiber. The obtained fiber has improved adhesivity to a matrix resin, especially thermoplastic resin and gives a molded article having remarkably improved mechanical strength by mixing with the resin and molding the mixture.

Title: Clutch device
Inventor: MATSUMOTO SHOGO
IPC: F16D23/12
Filed: 1995-03-24
Abstract: PURPOSE: To enable engagement and idle running by engaging a member with a first cam mechanism by a correponding force with torque at the one way rotation time of a pair of members and engaging the member with a second can mechanism by the corresponding force with a generation thrust and pushing force at the opposite direction rotation time and giving an energizing force for separating the member to the second cam mechanism. CONSTITUTION: The clearance between a first cam member 2 and a position 3 is increased by the normal rotation of a clutch disc 8 and the piston 3 and a second cam member 4 are pushed to the disc 8 and the member 4 is rotated normally and the cam surface of the member 4 raises the cam surface of the piston 3 through a second cam roller 6. The piston 3 is pushed back by the generation of cam thrust and the clearance between the member 2 and the piston 3 becomes minimum and the member 2 receives the reaction force of the cam thrust and the member 4 and the disc 8 are engaged by self binding. Thereby, the larger rotation torque, the larger engaging force.  When the disc 8 is reversely turned, the member 4 is also reversely turned by friction engagement and the member 4 is engaged with the disc 8 by the cam thrust and this engagement force is the sum of the cam thrust and an oil pressure. When oil pressure thrust is reduced by the energizing force of a spring 7, the engagement is released.

Title: Automatic link modulo selection system
Inventor: HASEGAWA KENICHI
IPC: H04L29/06
Filed: 1989-03-20
Abstract: PURPOSE:To communicate with the other party whether it is set to the non- extension mode or the extension mode is unknown by changing the mode to transmit a command again at the time of failing in connection as the result of the first command transmission and searching the communication adapted to a terminal machine of the other party to connect the terminal machine so that communication with the terminal machine is possible. CONSTITUTION:When connection cannot be confirmed by a connection state confirming means 12 though the command is transmitted to the other party whose mode (the non-extension mode or the extension mode) is unknown, the mode is changed by a communication mode confirming and changing means 14. The command of the changed communication mode is transmitted again from a command transmission means 11 to connect the terminal machine of the other party so that communication with this machine is possible. Thus, a terminal machine on the originating side can communicate with the terminating side irrespective of whether the data link layer supported on the terminating side is set to the extension mode or the non-extension mode.
