Title: Preparation of polyvinyl acetal resin
Inventor: ASAHINA KENICHI
IPC: C08F8/28
Filed: 1988-06-16
Abstract: PURPOSE:To obtain the title resin having an excellent degree of acetalation, solubility in solvents, heat resistance, etc., by using acetaldehyde and formaldehyde together as an aldehyde component and reacting them with polyvinyl alcohol under a specified reaction condition. CONSTITUTION:Polyvinyl alcohol is completely dissolved in water and an acid catalyst (e.g., hydrochloric acid) is added thereto. Then, acetaldehyde and formaldehyde are added to the polyvinyl alcohol soln. and the mixture was reacted by keeping them at 5-15 deg.C for 30min to deposit an acetalated product. After the deposition of the acetalated product, the reaction system is kept at a temp. above 45 deg.C and up to 75 deg.C pref. for 1hr or more. Then, the catalyst, salts and unreacted aldehydes are removed by washing and neutralization to obtain a fine particle polyvinyl acetal resin having little variations in the particle diameter. The obtd. resin is suitably used for preparing an adhesive for laminated sheets, etc.

Title: Controller for motor
Inventor: FUJITA EIJI
IPC: H02P27/06
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To obtain a controller for a motor, wherein the nonconformity of the drive of the motor stops immediately can be avoided for surely preventing the damage to the motor. SOLUTION: Sensing the feeding currents to a motor 1 with current sensors 12, 13, the sensed values thereof are fetched into a CPU 4 to obtain the sensed temperature of the motor 1. In a RAM 6, first to third reference temperatures preset by respective temperature setting switches 27-29 are stored. Then, when the sensed temperature exceeds the first reference temperature, the motor 1 is driven, using a preset cycle time which is longer than a standard cycle time by a cycle time setting switch 30 to reduce its heat-generation quantity. Meanwhile, when the temperature exceeds the second reference temperature which is higher than the first reference temperature, the motor 1 is stopped. Furthermore, when the sensed temperature becomes lower than a third reference temperature lower than the second one, the cycle time of the motor 1 is reverted to the standard cycle time. As a result, the motor 1 is prevented from stopping when it is overheated slightly.
