Inventor: KAWAI HIDENORI
IPC: C08G73/10
Filed: 1987-06-17
Abstract: PURPOSE:To obtain the title copolymer which can give a polyimide resin excellent in dimensional stability and mechanical properties, by adding an aromatic tetracarboxylic acid dianhydride to an amic acid prepolymer obtained from an aromatic diamine component and a specified amount of another tetracarboxylic acid dianhydride and then adding the remainder of said acid dianhydride to the mixture and reacting them. CONSTITUTION:An amic acid prepolymer solution is obtained by reacting 10-90mol.% aromatic diamine component (A) of, e.g., the formula (wherein R is H or a monovalent substituent, and n is 1-3) with 40-99mol%, based on component A, aromatic tetracarboxylic acid dianhydride (C) such as pyromellitic monoanhydride, biphenyltetracarboxylic monoanhydride, benzophenonetetracarboxylic dianhydride or a mixture thereof in an organic solvent (e.g., N,N-dimethylacetamide).

Title: Rotor stress forecasting turbine control system
Inventor: MATSUMOTO HIROSHI
IPC: F01D17/24
Filed: 1977-12-14
Abstract: PURPOSE: To prevent an excessively large stress from appearing in a rotor of a turbine upon application of parallel loads thereto by constituting the control system therefore such that an assumption is had after reaching the rated speed that an initial load is applied to the turbine, and then  a forecast is made of a stress which is to appear in the rotor due to the load whereafter the forecasted stress is compared with a predetermined allowable stress in order to provide parallel load  allowing conditions.  
     CONSTITUTION: A basic function of a control system 100 calculates, before entering a parallel load running, a stress which is forecasted to appear after entering the parallel load running, and compares the forecasted stress with an allowable predetermined stress to provide a parallel load allowance instruction 15 to a synchronous parallel load function 14. Whether a judging operation is required or not for judgement of parallel load allowance is judged by a judgement 130 therefor. A flow of processes is changed over to a parallel load allowance judgement 131 if a breaker 16 is in OFF position, and to an optimum load changing rate determination 144 if the breaker 16 is in ON position. As a result of the parallel load allowance judgement 131, a parallel load allowing instruction is applied to the synchronous parallel load function 14 if the allowable load changing rate is not judged as hold, whereas a parallel load inhibiting instruction is applied if the allowable load changing rate is judged as hold.

Abstract: PURPOSE:To detect an obstacle in the direction of travel by letting an obstacle sensor selectively operate according to the turning direction of a steering wheel, based on electrical signals inputted from an instrumentation means. CONSTITUTION:In the traveling condition of a vehicle 1, the CPU of a computer 11 measures a rudder angle theta of the steering wheel 2 and compares this rudder angle theta with the left maximum allowable angle thetal. When the rudder angle thetais narrower than the left maximum allowable angle thetal, the rudder angle thetais compared with the right maximum allowable angle thetar. When the rudder angle theta is also narrower than the right maximum allowable angle thetar, a sensor selecting signal to select a forward obstacle sensor 6 is outputted into a sensor change-over circuit 14 and then the forward obstacle sensor 6 is made to operate. Therefore when the vehicle 1 is in a forward motion, the forward obstacle sensor 6 can detect the obstacles ahead in the direction of travel, and on the other hand, a right/left obstacle sensor 8 or 7 can detect the obstacles when the vehicle is turning to the right/left, respectively. Thereafter a detection signal is outputted to the computer 11. Thus an obstacle in the traveling direction of the vehicle can be detected.
