Title: Developing method in two color copying system
Inventor: KARASAWA SHIYUUICHI
IPC: G03G13/01
Filed: 1980-01-25
Abstract: PURPOSE:To prevent an edge effect on a toner image, by adding a charge neutralizing substance into the first developing fluid in developing the latent images having different polarities on a latent image bearing body with toners different in polarity and color. CONSTITUTION:For example, when the part of the latent image of photoreceptor 1 corresponding to the black part of an original is developed with black toner TBL and the red part with red toner TR, and after developing the latent image with positively charged toner TR, it is developed with negatively charged toner TBL, red boarder R1 is caused around black toner image BL1 with white ground W1 left between them. In order to prevent border R1, to a red developing fluid are added a polar solvent, such as methanol or water as a charge neutralizing material, an anionic or cationic surfactant having hydrophilic groups and hydrophobic groups, a hydrophilic aliphatic acid, such as oleic acid, etc., so as to adjust electric resistivity of the developing fouid in the range of 10<5>-10<10>OMEGAcm. The edge effect is prevented in the last development by neutralizing the charge of the first developing fluid.

Title: Laser machining method
Inventor: MARUYAMA IWAO
IPC: B23K26/082
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To provide a laser machining method capable of enhancing production efficiency by reducing machining time of a work. SOLUTION: The irradiation position of a laser beam is moved at low speed from one end P to the other end Q of the machining part 44a so as to weld the part. Then, the irradiation position of the laser beam is moved at high speed from the end Q of the part 44a to another end P of a machining part 44b. At this time, the irradiation position is moved through the passing part 46a, however, since the laser beam moves this part 46a at high speed, it is free from melting and machining. This method is successively repeated so that all machining parts 44a-44h are welded.

Abstract: PURPOSE:To form an Al wiring or an Al alloy wiring of low resistance and high reliability, by forming an aluminum layer on a titanium nitride layer, after a titanium layer and a titanium nitride layer are laminated on a silicon substrate, fine routes are formed in the titanium nitride layer, annealing is performed in an atmosphere containing oxygen, and oxygen is made to permeate into the titanium nitride layer. CONSTITUTION:A Ti layer 2 and a TiN layer 3 are formed in order on the Si region 1 of an Si substrate. Inert gas, e.g. Ar ions 4, whose atomic radius is larger than that of oxygen ions are implanted with high energy, and driven in the TiN layer 3, thereby forming fine routes 5. When said TiN layer 3 is annealed in an oxygen atmosphere 6, oxygen gas comes into contact with the surface of the TiN layer 3; oxygen atoms permeate the inside through the fine routes 5, and are captured by traps; the TiN layer 3 is stabilized to prevent the oxygen atoms from permeating. A layer 8 composed of Al or Al alloy are deposited on the TiN layer 3 into which oxygen atoms are made to permeate in the above manner. Thereby barrier properties of the titanium nitride 3 are increased, and the reliability of the aluminum layer 8 is improved.
