Filed: 1994-12-20
Abstract: PURPOSE: To obtain an imide compound in a non-aqueous reaction system in a high yield by reacting a polycarboxylic acid anhydride derivative with at least one of the ketimine derivative of a compound having a primary amino group and the aldimine derivative of the compound and subsequently releasing a ketone or an aldehyde. CONSTITUTION: A polycarboxylic acid anhydride derivative is reacted with at least one of the ketimine derivative of a compound having a primary amino group and the aldimine derivative of the compound having the primary amino group. Subsequently, a ketone or an aldehyde is released to obtain the imide compound. Since water is not produced in the reaction system, and further since the ketone or the aldehyde not inhibiting the progress of the reaction is produced, the method does not require a special water-separating device in the production device. Thereby, a solvent can freely be selected, and a side reaction does not occur, because water does not exit in the reaction system. The polycarboxylic acid anhydride derivative is especially at least one of a maleic anhydride copolymer and a maleic anhydride graft copolymer.  The other compound is preferably a compound having a formamide group in the molecule.

Title: Lid rotating mechanism
Inventor: NONAKA HITOSHI
IPC: G11B33/02
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To position a lid quickly and securely with a simple construction. SOLUTION: A coil spring 28 by which a lid 12 is positioned while a cam 18 which is linked with a rotary shaft 16 is held by a pair of leg parts 28B and 28C. As a back-and-forth vibration of the lid is avoided by the holding force of the leg parts, the lid can be positioned quickly and securely and the appearance can be improved. Further, as the lid is held at the initial position while the cam is held by the pair of leg parts, when a device main part is carried, the back-and-forth vibration of the lid can be avoided. That is, the appearance when the device main part is carried is improved and, as the lid does not face the outside of the device main part, the possibility that a foreign object collides against the lid can be eliminated and the lid is protected from damage.  Further, as the lid is positioned by one coil spring, the number of components can be reduced and the assembly is facilitated.
