Title: Field construction with gypsum board
Inventor: MURATA YOSHIMI
IPC: E04F13/04
Filed: 1989-05-01
Abstract: PURPOSE:To shorten the period of construction at site by a method in which the surface of a gypsum board is provided with a sealer and an UV-hardening type resin layer, and the board is finished by sander in factory and subjected to a finish painting or decorated sheet lamination at site. CONSTITUTION:One side of a gypsum board 2 whose both sides are laminated with thick plates 3 is coated with a sealer 4 such as moisture-hardening type urethane resin and then with a ultraviolet-ray hardening type resin as a seal 5 which is in turn hardened by irradiation of ultraviolet rays. The surface of the board 2 is polished by sander to form a sufficiently flat and smooth finish face, and the boards 2 are sent to constructing sites. The boards 2 are attached to given places in site by turning the finish face toward the surface side and subjected to a finish painting or decorated sheet lamination. The construction period at site can thus be shortened and the scratch resistance and surface smoothness of the rigid UV-hardening type resin, as well as the adhesion of the board, can thus be raised.

Title: Terminal voltage controller for self-excited induction motor
Inventor: YAMASHITA RIYUUSABUROU
IPC: H02P27/06
Filed: 1978-09-05
Abstract: PURPOSE: To always retain the terminal voltage of a self-excited induction motor constant by controlling the firing phase angle of a thyristor in a power converter in response to the magnitude of an error signal of the terminal voltage and a set voltage value.  
     CONSTITUTION: A comparator amplifier 11 compares the terminal voltage of an induction motor 6 detected by a transformer 7 with the set voltage value of a voltage setting potentiometer 12 to detect and amplify the difference therebetween to produce an error signal to a phase controller 8. The controller 8 and a logic arithmetic firing circuit 9 control the thyristor firing phase angle of a power converter 4 in response to the magnitude of the error signal to alter the magnitude of reactive power. That is, when the load of the induction motor 6 is reduced to reduce the delayed reactive power, a capacitor 5 generates excessive lead reactive power to increase the exciting current to thereby increase the terminal voltage of the induction motor 6. Accordingly, the phase of the firing signal is controlled to flow large current at the reactor 3 to thereby reduce the lead reactive power by the capacitor. Thus, the terminal voltage of the induction motor can be always retained constant.
