IPC: B41J31/14
Filed: 1990-03-23
Abstract: PURPOSE:To enable producing a fine particle ink causing no uneven concentration of a print and having a good keeping quality by mixing a magnetic powder which is made hydrophobic in the surface through a dispersant treatment with a binding component, and by kneading and pulverizing the resulting mixture. CONSTITUTION:A magnetic powder 1 and a dispersant 2 are subjected to a mixed dispersion 4 in a solvent 3. The magnetic powder 1 is added for the purpose of using a fine particle ink 13 in a regenerated heat transfer image formation apparatus of which regeneration process is a magnetic-brush developing process. The dispersant 2 is used for the purpose of dispersing the magnetic powder 1 in a binding component 6; and anions, cations, nonionic surface active agent, superdispersant Sol Sperse, etc., are used singly or in admixture. It is also possible to use a coupling agent such as silane, organic phosphorus and silyl peroxide. In the mixed dispersion 4, a pulverization of the magnetic powder to primary particles by a homogenizer, etc., and a surface treatment through the dispersant are conducted at the same time. An excessive dispersant 2 is removed by filtering 5 from a dispersion composed of the magnetic powder 1, dispersant 2 and solvent 3. The magnetic powder treated by the dispersant is mixed with the binding component 6, colorant 7 and conduction agent 8 and subjected to mixed dispersion by kneading 9.

Abstract: PURPOSE:To prevent dusts from mixing in equipment to reduce the noise of equipment and to facilitate the heat control in the equipment by forming an opening in a variable area, and so controlling the area of the opening as to hold its inner temperature in a predetermined range. CONSTITUTION:The temperature for increasing the area of an opening in office equipment 11 is set to T deg.C. When this temperature arrives at the vicinity of the T deg.C, a compression coil spring 4 is pressed to be returned by the recovery force of a shape memory alloy coil 5, and a member 3 with a rack is moved leftward. Simultaneously, a pinion 2 is rotated clockwise, and a shielding plate 1 with a slit is moved rightward. That is, the relative position between the vent hole 12 of a sheath cover 6 and the slit 8 of the plate 1 is moved thereby to increase the opening area for ventilation of the atmospheric aid. If the inner temperature of the equipment drops, the member 3 is again pressed rightward by means of the compression force of the spring 4, the pinion 2 is rotated counterclockwise correspondingly to return the plate 1 leftward. Accordingly, the opening is closed.

Filed: 1989-03-27
Abstract: PURPOSE:To obtain an excellent antistatic characteristic by means of a light material at low cost by adding and making adhere a conductive zinc oxide fine powder of not less than 30wt.% to a natural organic fiber material. CONSTITUTION:To a natural organic fiber material, for example, to a water dispersion liquid of a wood pulp, a predetermined amount, preferably not less than 30wt.% of the fiber material, and desirably 40-95wt.% of conductive ZnO is added and stirred, to which a polymeric flocculant is added so as to agglomerate the pulp and to coprecipitate the conductive ZnO fine powder. Proper amount of an interfacial active agent can be added to the dispersion liquid or to the agglomerated material. After a sediment is filtered and dried, a conductive composition is obtained. On the other hand in a dry method, a dried wood pulp is once difibered by a mixer, or is stirred cracking and conductive ZnO is added thereto. In this case, it is preferred to add a very small amount of binder thereto. By adding an ion conductive agent to this mixed system, conductive property can be improved.

IPC: H03G1/04
Filed: 1983-04-27
Abstract: PURPOSE:To vary the gain of an amplifier circuit linearly by adding a collector current detecting circuit and a comparing and amplifier circuit for feedback control. CONSTITUTION:The collector current detecting circuit 13 is connected between the common connection point of collectors of transistors (TR) Q3 and Q4 and a power source +EB.

On the other hand, a variable voltage source 7 for gain control is connected to the inverted input terminal of the amplifier circuit 14, and its output terminal is connected to bases of the TRs Q3 and Q4 respectively. Consequently, the TRs Q3 and Q4 are controlled by a voltage corresponding to the difference between both inputs to the amplifier 14 to perform feedback control so that a voltage corresponding to the sum of collector currents of the TRs Q3 and Q4 is equal to the gain control voltage of the voltage source 7. Thus, the gain of the amplifier is varied linearly.

Filed: 1992-02-26
Abstract: PURPOSE:To dispense with a definition for allowing a work processing program and a host computer system to correspond to each other and to dispense with management and maintenance, and also, to execute a flexible operation. CONSTITUTION:When execution of a work processing program 113 is started, an address correspondence registration informing means 111 informs correspondence of its logical identifier and a physical address of a host computer system to a communication processor 21. An address correspondence registering means 212 registers the informed correspondence. Thus, at the time of controlling a data transfer addressed to the work processing program 113 from a terminal equipment 31, an address retrieving means 214 retrieves registered information by using its logical identifier as a key, and realizes a data transfer. On the other hand, when the work processing program 113 is finished, an address correspondence release informing means 112 informs release of the correspondence informed already to the communication processor 21. An address correspondence releasing means 213 eliminates the registered contents concerned, when the release of the correspondence is informed. Also, when a fault of the host computer system 11 is detected, as well, the registered contents concerned are eliminated.
