Title: Dust storage device
Inventor: KOBAYASHI ICHIJI
IPC: B65F1/00
Filed: 1978-02-03
Abstract: PURPOSE: To reduce noises and enhance working efficiency by providing a dust storage drum with front and rear storage rooms, providing the rear storage room with a charge port in the upper portion and with an internal transfer means in the lower portion, and providing the front storage room with a discharge transfer means in the lower portion so as to enable connection to a dust collection vessel or treatment device.  
     CONSTITUTION: Dust charged in a dust shoot 2 falls due to its weight into a rear storage room 7. Each time when a detector 20 detects the full amount of dust in the room 7, a screw 13 of an internal transfer means 10 starts rotation for feeding the dust into a front storage room 6. When a detector 39 detects the full amount of dust stored in the room 6, a cover 33 is opened and a discharge port 30 is connected with a charge port 32 of a dust collection vessel 31, and a screw 24 of a discharge transfer means 21 is rotated so as to discharge the dust. This constitution reduces noises and enhances working efficiency.

IPC: G03G15/08
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent the toner clogging in an aperture at the time of replenishing a developer housing section with toners from a cartridge by disposing an arched branch part facing upward between the opposite parts of a falling port from which the powder housed in a container falls by gravity. SOLUTION: The branch part 16 for dividing the flow of the powder 8 from above by forming the arch shape at a prescribed width so as to face upward is disposed between the opposite parts of the falling port 14 from which the powder 8 housed in the container 13 falls by gravity. Then, the powder 8 falls while the flow is divided by the outer side of the arch shape of the branch part 16 when the powder 8 in the container 13 falls from the falling port 14. At this time, the space on which the pressure of the powder 8 does not act is formed on the inner side of the arch shape of the prescribed width of the branch part 16 and, therefore, the powder 8 facing the space collapses and falls and the collapse progresses like chain reaction. The clogging of the powder 8 in the falling port 14 is thus prevented and the smooth falling of the powder 8 is assured.

Abstract: PURPOSE:To obtain stable contact between a magnetic head and a tape even when the rigidity of the tape is small or the relative speed of the head and the tape is fast by changing the width of a core of the magnetic head of a magnetic recording apparatus. CONSTITUTION:The width 6 of a core of a magnetic head at the side of a tape exit 7 from a head gap 1 is made narrower than that at the side of an entrance 8. The core width 6 is made gradually smaller towards the exit 7. Therefore, when it is seen from the sliding face of the magnetic head, the part of the core at the exit 7 is streamlined, and the minimum core width 6 is smaller than the width of the track. This magnetic head is so shaped as above. When the magnetic head is to be processed so that the core width 6 is smaller at the exit 7, it is done immediately before the head is sliced to a chip from a block.
