Filed: 1982-10-19
Abstract: PURPOSE:To enhance the effect of breaking a bridge with an air jet stream by supplying an air jet stream from an air jet nozzle for breaking a bridge of granular powder accompanied by air and granular powder supplied from other portions through a supply path. CONSTITUTION:In case of opening a discharge port gate 8 of a hopper 7 to feed out the stored granular powder 9 to a discharge chute pipe 11, if granular powder 9 builds a bridge 9a not to be discharged, an air jet stream 13 is sprayed from an air jet nozzle 12 to the bridge 9a to be broken. At this time, the air jet stream 13 is forced to pass at high speed in one end portion of a pipe 10 connecting the side wall portion of the hopper 7 to the side wall portion of the discharge chute pipe 11, so that air and granular powder 9 in the pipe 10, the discharge chute pipe 11, and in the lower portion of the hopper 7 are sucked in the air jet stream 13 to be accompanied therewith. Thus, the apparent amount of air is increased to reliably break the bridge 9A with strong force.

Title: Magnetic erasing head device
Inventor: INADA KENKICHI
IPC: G11B5/17
Filed: 1986-08-08
Abstract: PURPOSE:To reduce the variance of a resonance point and make a device suitable for mass production by attaching a chip capacitor instead of an electrolytic capacitor which is conventionally soldered for the purpose of attaining resonance to a head winding coil. CONSTITUTION:A head winding 1 functions as a coil to attain resonance to the capacitor, and a head base 2 supports a head chip and fixes it to a rotary cylinder, and a terminal strip 3 relays the head winding to the cylinder, and a copper foil pattern wired on the terminal strip determines the attaching position of a chip capacitor 5. When the chip capacitor is mounted on the head base, the distance between the capacitor and the head winding coil is about 10mm, and this distance is reduced to about 1/4 because this distance is about 40mm in case of attachment of the electrolytic capacitor on the cylinder. Thus, the laying capacitor of a connection cable is reduced to at least 1/4 to reduce the variance of the resonance point.
