Title: Electrophotographic developing agent
Inventor: TSUBUSHI KAZUO
IPC: G03G9/12
Filed: 1987-03-13
Abstract: PURPOSE:To improve the image density, the resolving power and the sticking property of a toner particle, and to prevent the toner particle from offset by incorporating an olefinic resin having melt-index of 25-700 in the toner particle. CONSTITUTION:The toner particle contains at least the olefinic resin having the melt index of 25-700. The olefinic resin having the melt index of 25-700 has a polar group such as carboxyl, hydroxy, glycidyl or amino group in a molecular chain of polyolefin or a structure partially cross-linked by a cross- linking agent or a radical initiator. Therefore, in case that said resin together with a pigment are used for the toner particle, the toner particle has the good dispersibility. The resin is difficult to suddenly produce the plasticity in a state of dispersing the resin in a solvent or in the fixing step of the dry toner or the wet toner, thereby making the difficult to fuse the toner to a fixing roller. While, the toner increases the fixing property in the state of solidifying the toner by cooling, owing to the high mol.wt. of said resin.

Filed: 1992-02-13
Abstract: PURPOSE:To enable an overvoltage to be absorbed by a surge absorbing element by forming a slight clearance between a surge absorbing portion and an electrode, and.sealing gas between the electrodes by insulative coating member. CONSTITUTION:A cylindrical ceramic (insulator) 1 has a large center and both narrow ends.

Terminals 4 are jointed to the ceramic portion at the narrow ends via metal caps 3, thereby providing electrodes. A slight clearance 7 is formed between the metal cap 3 and the surge absorbing portion. Sealing gas is sealed between the electrodes with the terminals 4 fixed thereto by an insulative coating member by utilizing the surface nearest the electrode of the carbon alloy in the broad center portion and the cross section of the metal cap 3 nearest the electrode. Consequently, a surge voltage is absorbed by the surge absorbing portion so that durability of a surge absorbing element is enhanced.

Abstract: PURPOSE: To strongly weld a lead plate to an electrode with the simple method by forming a dowel of a projecting part to be pushed for welding into the elliptic shape at the time of spot-welding a lead plate to an electrode of a battery. CONSTITUTION: A dowel 1A to be spot-welded to an electrode 2 of a battery is provided in a lead plate 1 by pressing. At the time of spot-welding, the projecting surface 1a of the dowel 1A, of which top surface is pushed by a welding pushing electrode 3, is made to contact with the electrode 2 and welded to the electrode 2 by the large current from the pushing electrode 3. Even in the case where area of the elliptic dowel 1A is increased, a space between the side edge of the lead plate 1 is increased so as to increase the area of the peripheral part 1b of the dowel 1A. Consequently, contact area with the pushing electrode 3 is widened, and the large current is evenly flowed over the whole of the peripheral part 1b so as to securely weld the dowel 1A to the electrode 2.  Ratio of the short diameter and the long diameter of the elliptic shape of the dowel 1A at 1.5-2 times is desirable. Plural dowels 1A are desirably provided in parallel with each other at a local part of the lead plate 1.
