Abstract: PURPOSE:To make pressure contact with a detecting means to a developer replenishment tank without using a pressing part necessary to press-contacting as a separate part by fitting the developer-detecting means into a storage part, and pressuring contact with the detecting means to the developer replenishment tank with a projection, integrated with an attaching part, curved. CONSTITUTION:The projection 31, integrated with the attaching part 14a, and the toner sensor 24 are arranged in the storage part 14b of the attaching part 14a of a support frame 14. The projection 31 and the storage part 14b are made of resin, etc., and integrated so that the projection 31 extends upward from the bottom of the storage part 14b and can curve or bend. Further, the toner sensor 24 is secured to the projection 31 and fixed in position. By attaching the toner replenishment tank 20 to the attaching part 14a, the detection face 24a of the toner sensor 24 strikes against the external surface of the toner replenishment tank 20. At the time, the projection 31 is caused to curve or bend by the toner replenishment tank 20 via the toner sensor 24, so that the toner sensor 24 is made pressure contact with the external surface of the toner replenishment tank 20 by the elasticity of the projection 31 and held in position.

Title: Filter apparatus
Inventor: OGAWA YONEKICHI
IPC: B01D35/027
Filed: 1982-03-20
Abstract: PURPOSE:To provide a small filter apparatus with good efficiency constituted so as to be capable of obtaining sufficiently high filtration capacity by two filter materials arranged in an upper and a lower filter chambers even if the volume of a filter case is made small. CONSTITUTION:A dense filter material 7 arranged in an upper filter chamber 4 easily generates clogging compared to a coarse filter material 8 accommodated in a lower filter chamber 5 but, because water in a water tank 1 is always flowed into the downstream chamber 30 of the upper filter chamber 4 from a lower water sucking port 16 through the coarse filter material 8 having relatively low water passing resistance in the lower filter chamber 5, water sucking force is always generated in the downstream chamber 33. Therefore, water in the upstream chamber 37 of the upper filter chamber 4 is sucked into the downstream chamber 33 through the dense filter material 7 without interrupting a water flow from the upstream chamber 37 to the downstream chamber 33 and good filtering action due to the dense filter material 7 can be continued over a long period of time.

Filed: 1979-04-16
Abstract: PURPOSE: To prevent the collapse of a hollow member so as to increase the workability, by encapsulating a pressurized medium into a hollow member to be internally chilled, then by forcing molten metal into the cavity of a mold.  
     CONSTITUTION: A hollow member 3 having thin wall is filled principally with a pressurized medium which increases the pressure in the hollow member 3 by its volume expansion, and the hollow member 3 is closed at the openings with plugs 5, 5. The hollow member 3 is recessed into the fitting grooves 13 formed in the cavity 12 of a mold 6, then the mold 6 and another mold 9 are clamped so that the hollow member 3 is fitted to the corresponding fitting grooves made in the mold 9. Die casting operation is conducted by, for example, pouring molten metal with a metal-charging device into sleeve 10, then by forcing the molten metal into the cavity. The molten metal forced into the cavity envelopes the hollow member 3 and fills the cavity, in addition, expands the volume of the medium so as to increase the inner pressure, consequently the hollow member 3 is prevented from being collapsed.
