Title: Corrugated acrylic sheet
Inventor: KAMIYOSHI HIROAKI
IPC: B29C61/00
Filed: 1979-09-07
Abstract: PURPOSE: To form an acrylic resin sheet into a transparent corrugated sheet which is thin and excellent in strength by forming a polymethyl methacrylate resin sheet through biaxially extending orientation into the sheet of corrugated shape.  
     CONSTITUTION: While the methyl methacrylate resin is extruded by an extruder, it is successively drawn biaxially longitudinally and laterally by a data method and thereby a sheet is prepared. Then, it is formed into the sheet of corrugated shape, preferably under the temperature of about 100°C or below by a hot press. Since it is given the biaxial drawing orientation, its strength (against shock, tension and bending) is great, while it is inexpensive as it can be thinned. By thinning, the radiuses of curvature of the back and front thereof approximate to each other, the aperture in the overlapping part is eliminated, whereby the sealing property is improved.

Title: Multiphase switching circuit between ac power source and load and load control unit using same
Inventor: GIRUBAATO SHII DOYUMON
IPC: H02P7/00
Filed: 1982-07-02
Abstract: An electrical switching circuit for a multi-phase a.c. supply uses semiconductor rectifier switches SCR1 to 5 to reversibly switch power to a multi-phase electric motor so that the motor can be run in a forward or a reverse direction. The SCRs are provide in two sets, one for switching power to forward run the motor, and the other set for reverse running of the motor. Inductor elements  DELTA L are connected in series with the SCRs. The inductor elements comprise coils which include a non-linear permeability core, for example of ferrite or permalloy, which are operative to suppress voltage transients at switch on of the motor. These transients would otherwise produce spurious firing of the SCRs and could produce a short circuit across the input phases of the a.c. supply. The circuit is used in a valve actuator. Improved torque limit switches and position limit switches are disclosed, which operate a low voltage and which use Reed and wall effect switches.
