Title: Commutatorless motor
Inventor: AKAMATSU MASAHIKO
IPC: H02P6/14
Filed: 1978-09-14
Abstract: PURPOSE: To effectively perform a commutation enhancement action in a low-speed region and to obtain sufficient magnetic fluxes at a high-speed region by increasing the average current value of dc field windings than a specified value, as the speed of a synchronous machine increases from the lower speed.  
     CONSTITUTION: A field currect IF 1  is supplied as a specified current value during the time of non-commutation at the low speeds when commutation is to be enhanced. By selecting said IF 1  in the reigon wherein the slope of magnetic saturation characteristic curve is relatively steep, the magnetude of ΔIF 0 , which is required to obtain magnetic flux variation Δϕ to get the emf for the commutation enhancement, can be greatly reduced. On the other hand, during the time of high-speed operation in which commutation is not required to be enhanced by increasing the field current from a specified value by ΔIF 0 , the current in dc magnetic windings is increased to the value larger than the specified value IF 1 . In this constitution, torque per same armature current in the high-speed region, wherein commutation is made by the internal emf, can be increased sufficiently.

Filed: 1985-05-27
Abstract: PURPOSE:To manufacture a plastic optical information recording board having no birefringence, by providing an ultrasonic oscillator applying an ultrasonic wave within a cavity. CONSTITUTION:Resin is injected into a cavity 11 from a gate 9 through a nozzle 4. Then an ultrasonic wave is applied to a stamper 3 from a horn 5 by making an ultrasonic oscillation circuit 7 and ultrasonic oscillator 6 drive. Fluidity of the resin which is in the cavity 11 becomes favorable through the ultrasonic wave which has been applied to the stamper 3. An ultrasonic oscillation is kept applying to a cavity side part 1 and rear cavity 2 until the resin is cured by cooling the cavity side part 1 and rear cavity 2 while the ultrasonic wave is being applied to the resin like this. Through a process like this, it follows that the fluidity of the resin entered into the mold becomes favorable, orientation based on a flow of the resin at the time of cure is prevented, optical anisotropy is prevented and birefringence can be prevented.
