IPC: D06F37/40
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent the degradation in the axial center accuracy of two parts by the occurrence of seizure at the time of press fitting of shaft parts which are formed by exactly obtaining the axial center accuracy of the two parts consisting of a large- diameter part and a small-diameter part and press fitting these parts in the small diameter part and for which strength is required. SOLUTION: A narrow region at one end in a fitting and press-fitting range of the large-diameter part 7 and its shaft part 8 is provided with a slightly large press- fitting interference part and the other portion of the fitting region is provided with a slight clearance region for guiding both parts so as to align their axial centers to each other. The opposite end to the end provided with the press-fitting interference part is provided with a clamping and gripping area, such as slight deformation. The process may be simultaneous or may be divided. As a result, the press-fitting interference part is not arranged evenly over the entire region of the fitting and press-fitting range but is arranged preponderantly therein, by which sufficient strength is obtained and the chances for the seizure are drastically decreased.  Since the axial centers may be sufficiently aligned in the above fitting the guiding part, the high-strength and high-accuracy axial press-fitting and coupling are made possible.

IPC: G05B13/00
Filed: 1989-08-23
Abstract: PURPOSE:To eliminate the mutual interference between the variable structure PI control and the equivalent disturbance compensation control and to attain the stability of a multi-function type controller by providing a function which varies the equivalent disturbance compensation value based on the deviation value. CONSTITUTION:A function signal generating part 6 is provided at the output side of an equivalent disturbance compensating part 5, and the equivalent disturbance compensation output is varied based on the deviation (e) and fed back. In other words, the deviation (e), i.e., the input of a variable structure PI control part 1 is detected. Then the equivalent disturbance compensation is stopped when the deviation (e) is large, and the deviation (e) is settled by the variable structure PI control only with no overshoot. When the deviation (e) is set at a certain level or less, the equivalent disturbance compensation is carried out again. At the same time, a proportional coeffi cient K which varies the equivalent disturbance compensation value by the deviation (e) is turned into a function. Thus it is possible to suppress the mutual interference between a variable structure PI controller and an equivalent disturbance compensating part without deteriorating the characteristics of control functions of both parts via the control of the equivalent disturbance compensation value carried out just with supplication of a relational formula (K - e).

Following this procedure, the polyester sheet is heated under pressure and after heating, the sheet is gradually cooled as it is pressed to be followed by the action to release the pressing operation. Thus the decompressed state is returned to a normally pressed state and the polyester sheet is taken out. The preheating temperature should preferably be lower than the glass transition temperature Tg of the polyester sheet and the heating temperature be Tg+10 to Tg+50 deg.C. In addition, the pressing force should preferably be 3 to 291g/cm<2>.
