  • Patent number: 4705656
    Abstract: A method for producing spherical metal particle uses a molten metal reservoir for containing a molten metal, a rotary drum having a number of teeth onto which the molten metal is to be adhered one after another and a driving means for rotating the rotary drum so that the molten metal adhered to each of the teeth can be scattered from the teeth before even a part of each molten metal adhered to the teeth solidifies. At least one tooth of the rotary drum is dipped into the molten metal contained in the molten metal reservoir. The molten metal adhered to the teeth is scattered from the teeth before any portion of it has solidified by means of centrifugal force acting on the rotary drum. The molten metal assumes a spherical or similar shape during its trajectory due to surface tension. It cools by atmospheric cooling to solidify as discrete metal particles of substantially uniform diameter.

  • Patent number: 4701681
    Abstract: Disclosed is a starting device for a toy motor using an ultrasonic wave signal. The starting device comprises a transmitter external to the toy which generates an ultrasonic wave signal and a receiving and starting element disposed within the toy for receiving the transmitted ultrasonic wave signal and starting the toy motor. In a preferred embodiment, the motor drives a sound reproducing device. The ultrasonic wave signal from the transmitter is received, amplified, and detected, and when the detected output reaches a predetermined level, a switching transistor forming an energization path to the motor is turned on to start the motor. Once the motor is started, a self-holding switch associated with the switching transistor causes the switching transistor to supply continuous current to the motor even when the transmission of the ultrasonic wave signal has been terminated.

  • Patent number: 4305520
    Abstract: A storage apparatus for removably receiving planar members, such as business records. The storage apparatus comprises a storage container having front and rear wall portions and a pair of spaced rods extending horizontally therebetween. A file envelope is adapted to be removably inserted into the storage container. The file envelope is formed with front and rear upstanding walls, each including an aperture located along the side edge. The apertures engage the pair of spaced rods in the storage container to enable the file envelope to be placed on and slidingly supported by the rods. Removable securing members are placed along the side edges of the file envelope on the rods in the storage container.
