Title: Sliding member and its production
Inventor: SUGAFUJI AKIYOSHI
IPC: F16C33/12
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To obtain a sliding member excellent in sliding property and wear resistance with a simple equipment without using a salt bath by providing a solid lubricant coating film of a sulfide or a multiple compound consisting essentially of the sulfide on the surface of an iron based metallic base material and nitriding the sulfide by a gas equal to or above one time. SOLUTION: MoS2 and WS2 individually or in combination or further mixed with a solid lubricant such as graphite, BN are dispersed in an organic or inorganic solvent to be made colloidal and applied on the iron based metallic base material, which is desirably dried and after that, nitrided. Though the nitridation is optional if performed in the gas, a gas soft nitcidation is most suitable and is performed by housing the iron base metallic base material in a nitridation furnace heated to and kept at 500-600 deg.C, introducing gaseous ammonia and RX gas in the nitridation furnace to react and generating activated nascent nitrogen (2N) and carbon (C) to infiltrate into the iron base metallic base material. As a result, the sliding member having a 3 layer structure of the solid lubricant coating film, a porous layer and a nitride layer is obtained.

IPC: B41J2/055
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To shorten an image-printing time by constituting two pressure chambers to discharge ink as one group in a shear mode type ink jet printer head. SOLUTION: An ink jet printer head 1 is formed including a plurality of diaphragms 3 of piezoelectric ceramics, pressure chambers 4 formed between the diaphragms 3, electrodes 6 for driving which are formed to both side faces of each diaphragm along a longitudinal direction, and electrodes 10 for controlling an ER ink which are formed to the vicinity of ink jet holes 7. The ER ink is introduced as ink to each pressure chamber 4. When a given diaphragm 3 is bent to pressure a pressure in the pressure chamber 4 thereby discharging the ink, electricity is supplied between the electrodes 10 formed opposite to two diaphragms 3 constituting the pressure chamber 4 adjacent to the pressure chamber, thereby increasing a viscosity of the ER ink apparently. The air is prevented from invading from the ink jet holes 7. The ink is sequentially discharged from two pressure chambers as one group.

Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To provide a highly precise active matrix semiconductor display device with high resolution by supplying a gradation signal to a picture element TFT plural times corresponding to prescribed picture information. SOLUTION: The gradation signal is supplied to the picture element TFT selected by a scanning signal during a first sub-selection period(TSS1 ) and holding voltage rises. Then, it becomes a non-selection period (Tns) and the holding voltage of the picture element drops. In a second sub-selection period (TSS2 ) after the non-selection period(tns) terminates, the gradation signal similar to the signal supplied in the first sub-selection period (TSS1 ) is applied to the picture element TFT and the dropped holding voltage of the picture element rises. Thus, the drop of the holding voltage of the picture element can be reduced to a minimum by dividing the selection period (Ts) when the gradation signal corresponding to the prescribed picture is supplied into four sub-selection periods (TSS1 -TSS4 ) and supplying the same gradation signal to the picture element TFT.
