Title: Electrophotographic liquid developer
Inventor: AMARIGOME KISHO
IPC: G03G9/12
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To rapidly restore the charged site of a toner after ionic dissociation to the rechargeable original state by incorporating an acidic material having a skeleton similar to that of a material which contributes to charging the toner, soluble in a carrier fluid and having a low molecular weight. SOLUTION: A toner is dispersed in an electric insulating carrier fluid and an acidic material having a skeleton similar to that of a material which contributes toward charging the toner, soluble in the carrier fluid and having a low molecular weight is incorporated to obtain the objective electrophotographic liquid developer. The charged site of the surface of the toner is neutralized after ionic dissociation with a counter ion derived from the acidic material and the toner is restored to the rechargeable state. The acidic material has high mobility because of its low molecular weight and can rapidly neutralize the charged site.  Since the acidic material has a skeleton similar to that of the material contained in the developer, the state of the charged site varies hardly before and after ionic dissociation and the charged state is restored to a state close to that before ionic dissociation. Thus high chargeability of the toner is retained, the lowering of image quality is suppressed even after repeated image formation and high printing durability is ensured.

Filed: 1987-04-10
Abstract: PURPOSE:To take a measurement through simple constitution by shifting the coordinates of a taught position to which shift information is added according to the deviation between a measurement start position taught in a storage device and an actual measurement start position on a body to be measured which is measured by a sensor. CONSTITUTION:A shift command setting function device 6 adds shift information to an optional taught point among plural taught points.

Abstract: PURPOSE:To improve yield on production of a thin-film magnetic head by etching a permalloy thin-film formed onto a substrate in an etching liquid containing ferric chloride, hydrochloric acid and phosphoric acid so that the film thickness of a side surface is gradually decreased taperingly. CONSTITUTION:The permalloy thin-film 2 with thickness such as 2mum film thickness is formed to the ceramic substrate 1 through a resistance heating evaporation method. A photo-resist film with thickness such as 1.5mum film thickness is shaped onto the thin-film 2 in predetermined form through a rotary application method, and a photo-resist pattern 9 is shaped through exposure and development. The pattern is etched taperingly by the etching liquid containing the ferric chloride, the hydrochloric acid and the phosphoric acid. The angle of taper theta can easily be adjusted by changing the concentration of the phosphoric acid. Accordingly, the pattern can easily be etched taperingly without damaging the magnetic characteristics and the surface of the substrate, and yield on production of the thin-film magnetic head can largely be improved.

Filed: 1985-04-26
Abstract: PURPOSE:To easily release ink from the base film of an ink ribbon, by arranging a conductive string like member along a direction providing the ink ribbon under tension to a cassette and making the string member heatable by the supply of a current. CONSTITUTION:A thin strip part, which corresponds to 2-3 characters in this side from a cut-out window 11A, with respect to the moving direction of an ink ribbon 14 is set to a strongly heating part 11B and constituted of a material having resistance value higher than that of the other thin strip part 11C. A current is supplied to a thin strip 11 and the ink ribbon 14 is heated at the strongly heating part 11B by the Joule heat of the electric resistance of the thin strip and the viscosity of ink is lowered to perform printing. An energizing signal is supplied to a heating part 24 by a printing order to start the heating of the ink ribbon. When thee is printing, printing and moving operation are repeated in a heated state. Because the ink ribbon is heated immediately before guided to a printing position and the viscosity of ink is lowered and the ink becomes easy to release from a base film, printing with sufficient density can be obtained even if the impact force of a hammer is weakened.

Filed: 1992-04-09
Abstract: PURPOSE:To lighten the shock to other equipment accommodated in the same casing by providing a shock absorbing member, which lightens the insertion force on and after the set point when inserting a device along a guide, a lever, and a stress direction converting means, which converts the force in vertical direction of a lever into the force in direction of insertion and extraction after the shock absorbing means starts operation. CONSTITUTION:As a disk unit case 1 is pushed into an accommodation case (casing), holding a handle 12, a mobile pin 15 hits against the shock absorbing member 8 attached to a guide plate 9, and lock comes off. Since the ratio of the push-down distance of the handle to the push-in distance can be set freely by changing the set angle of the inclination of the guide groove of the guide plate 9, the speed or the strength of engagement can be added or reduced by adding or reducing the speed or the strength of the press-down of the handle 12. Moreover, the push-in force is lightened by its hitting on the shock absorbing member 8, the shock given to other disk units is lightened.

Abstract: PROBLEM TO BE SOLVED: To reduce the size of a joint part and to allow characteristics impedance to be close to that of a connected pattern by inserting a plurality of microbumps for jointing them between a semiconductor connection pattern and a substrate pattern. SOLUTION: A plurality of small bumps 2 are formed side by side square to the signal flow on a semiconductor connection pattern 4, then a semiconductor 1 with the bumps 2 formed is placed on a substrate 5, which is heated and pressurized so that a pattern 3 on the substrate is jointed to a pattern 4 on an IC with these plural small bumps. Thus, the electrical length of the joint part is significantly reduced, while an electrical transfer characteristics relative to a high-frequency signal of the joint part is allowed to be similar to the transfer characteristic of the substrate pattern 3 and a semiconductor connection pattern 4. Since the difference between both characteristics impedances is reduced, high-frequency electrical characteristics at the joint part is significantly improved.

Filed: 1993-03-24
Abstract: PURPOSE:To contrive the retaining of a thermal efficiency by a method wherein the flow rate of hot-water supplied to an indoor machine is turned down when the load of heating is lightened and the temperature of returning hot-water rises. CONSTITUTION:When the room temperature rises, the load of heating is reduced and the temperature of returning hot-water from an indoor machine 4 rises, a flow rate changing valve 6a is choked and the flow rate of hot-water is reduced. On the other hand, the temperature of hot-water supplied to the indoor machine 4 is kept constant at all times by a temperature control device 12 and, therefore, the amount of heat supplied to the indoor machine 4 is reduced and, as a result, the amount of heat corresponding to the load is supplied. Accordingly, the temperature of returning hot-water is reduced to an initial temperature and the thermal efficiency, reduced temporarily, is returned to the initial efficiency soon. By method, the thermal efficiency can be retained.
