Title: Polycarbonate and its production
Inventor: TOTANI YOSHIYUKI
IPC: C08G64/14
Filed: 1993-07-16
Abstract: PURPOSE:To produce a polycarbonate having reactive terminal groups by adding a dihydroxy compd. and a terminal stopper first, then a carbonate precursor in the presence of an acid acceptor, and finally a catalyst to an org. solvent to thereby conduct polymn. and thermally treating the resulting product. CONSTITUTION:1mol of a dihydroxy compd. (e.g. bisphenol A), 2-10mol% 4-(2'- propenyloxy)phenol, and at least 1mol of a carbonate precursor (e.g. phosgene) are reacted in such a manner that to an org. solvent are added first the dihydroxy compd. and the terminal stopper, then the precursor in the presence of an acid acceptor (e.g. NaOH), and finally a catalyst (e. g. a tert. amine). The resulting product in an aq. soln. is concentrated by heating to give a polycarbonate having reactive terminal groups of formulas I and II (wherein Z is an aliph. hydrocarbon group having a double bond; Ar<1>, Ar<2>, and Ar<3> are each a divalent arom. group; and X is a group linking Ar<2> to Ar<3>) or reactive terminal groups of formulas III and IV (wherein Z' is an aliph. hydrocarbon group having a double bond; Ar<4> and Ar<5> are each a trivalent arom. group; Ar<3> is a divalent arom. group; and X is a group linking Ar<5> to Ar<3>) formed by thermal rearrangement of groups of formulas I and II.

Title: Image recorder
Inventor: SATO FUMIO
IPC: H02K37/22
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To provide an image recorder which can improve the image quality by improving the rotational accuracy of a stepping motor functioning as a main driving source without making the recorder main body large in size. SOLUTION: A photoreceptor drum 1 is constituted so as to be provided with a mass by which an inertial load is imposed on the stepping motor 9. Concretely, a drum-like photoreceptor 1a is formed by forming a photoconductive layer on the surface of a cylindrical aluminum pipe stock and a load member 1b having the mass by which the inertial load is imposed on the motor 9 is stuck to the inside circumferential surface of the photoreceptor 1a. Thus, a vibration component can be eliminated by the rotation of the drum 1 when the motor 9 is driven and the rotational accuracy of the motor 9 is improved. Further, by improving the rotational accuracy of the motor 9, the noise is also reduced when the motor 9 is driven.

Title: Interruption holding register control system
Inventor: NAGASAKI SATOSHI
IPC: G06F13/24
Filed: 1988-07-18
Abstract: PURPOSE:To decrease the load of a system bus by transferring the information between an I/O adapter and a central processing unit and setting the interruption request information to an interruption holding register in the central processing unit. CONSTITUTION:When an I/O adapter 6 issues a command, by transferring the information to set an interruption holding register 3 besides the information transferred by the command, a system bus 5 can be efficiently used. For example, the I/O adapter 6 simultaneously sends the setting information of an interruption bending latch 2 with a command to send a vector to a CPU 1. By sending simultaneously the setting information of the interruption bending latch 2 even with the command to communicate between the CPU and the I/O adapter 6, this can be set. Thus, the load of the system bus can be decreased.

Title: Coaxial connector device
Inventor: YUNOKI SHUICHI
IPC: H01R13/40
Filed: 1991-06-21
Abstract: PURPOSE:To easily connect and remove a shaft portion and a housing without requiring a removing jig by providing the hole portion of the housing of a coaxial connector with a snap out for contracting the retention spring of the shaft portion. CONSTITUTION:When a shaft portion 50 is inserted into the hole portion 52A of a housing 52, the leading end portion 51A of a retention spring mechanism 51 abuts on a housing port 52B to contract as short as tire inner diameter dimension of the hole portion 52A due to its spring property for sliding. And, when the leading end portion passes through the hole portion 52A, the leading end portion restores its dimension due to its spring property Thus, the shaft portion 50 is held by a trailing end portion 51C and the inner diameter of the hole portion 52A. Meanwhile, in removing the shaft portion 50, when the handle portion 2B of a snap out ring 2 is moved to left, a projected portion 2A abuts on the leading end portion 51A of the mechanism 51 for press and contraction. Thus, it is possible to remove the shaft portion 50 from the housing 52. This requires no removing jig and can easily connect and remove the shaft portion and the housing.
