Title: Electrophotographic device
Inventor: SATO NORIHIDE
IPC: G03G15/08
Filed: 1990-10-01
Abstract: PURPOSE:To set the feed-out quantity of toner smaller than the feed-in quantity of toner and to prevent the toner from being flocculated by making the diameter smaller for a coil spring which is positioned distant from a developing means out of the springs stretched and laid between plural feeding arms in a toner hopper. CONSTITUTION:When the toner 14B is fed to a toner discharging roller 19, for example, the excessive toner is prevented from being fed and being flocculated on a toner discharging roller 19B, because the rotating speeds of 1st, 2nd and 3rd toner feeding members 51, 52 and 53 are the same but the diameters of the 1st, the 2nd and the 3rd coil springs 51C, 52C and 53C are constituted to successively get smaller, and the feeding quantity of the toner by the members 52 and 53 is small consequently even though the member 51 is going to feed the excessive toner 14B to the roller 19B. Furthermore, the coil spring is made of a wire having about 0.1mm diameter so as to prevent the toner from being pressed and stuck to the toner hopper 15B.

Title: Controller for safety valve
Inventor: EDERUBERUTO TEIIFUENSARERU
IPC: F16K17/10
Filed: 1989-10-12
Abstract: PURPOSE: To quickly open a safety valve by forming connection to a servopiston side separated apart from a main lid on the flow-out side of a pilot lid and opening the main lid by means of a load based on a servopiston when the pilot lid is opened. CONSTITUTION: When vapor inside a flow-in chamber 6 is increased to a critical pressure, a pilot lid 20 is lifted and vapor flows from a chamber 28 to a chamber 12. According to an opening action of the lid 20, a pressure inside the chamber 28 is lowered, and the piston 26 is lifted, so that an extension part 32 is engaged with the lid 20 so as to open it further. Consequently, a pressure inside the chamber 12 is increased, and a servopiston 5 presses a lid 3 downward, so that vapor flows outward via a vapor chamber 7 and a bore 8. When a pressure inside a chamber 6 is lowered, a spring 23 closes the lid 20, and the piston 26 is returned to an initial position. A pressure inside the chamber 12 is lowered via a throttle part 15, and the lid 3 is closed.  In this way, condensation is prevented from being accumulated inside the chamber 12, so that a safety valve can be quickly operated without any obstruction.

Title: Pattern forming material
Inventor: ENDO MASATAKA
IPC: G03F7/039
Filed: 1987-10-20
Abstract: PURPOSE:To prevent the reduction of the resolution and contrast of a resist pattern by incorporating a resin contg. specified bonding repeating units and a solvent. CONSTITUTION:This pattern forming material contains a resin contg. repeating units represented by formula I and a solvent. The resin is a positive type material which is insoluble in an aq. alkali soln. before exposure and is made soluble in the soln. after exposure. Since styrene is used as a monomer, the resin has little absorption at about 249nm wavelength and is suitable for the pattern forming material. Diethylene glycol dimethyl ether having little absorption at 249nm may be used as the solvent so that the solvent slightly remaining after coating does not deteriorate the performance of the resulting resist by absorption. When the pattern forming material is exposed and developed, a resist pattern can be formed with high contrast, high resolution and sensitivity.
