Title: Microprogram control system
Inventor: OKUGAWA SHINICHI
IPC: G06F9/22
Filed: 1986-02-12
Abstract: PURPOSE:To execute the flexible and dynamic multibranching without delaying executing speed by providing a flag to control a multibranching instruction and executing the multibranching with a branching address entry table. CONSTITUTION:The system has an entry table group to store a branching address and a field to designate the number of an entry table, and is equipped with a multibranching instruction group to be able to execute the branching with the entry table, a register group to store the mode whether or not the entry table is used and a microinstruction group to set the value to the register group. When the multibranching instruction is issued, by the value of the register group, it is changed over whether the multibranching instruction is executed as it is or the branching is executed by using the address obtained from the table of the number designated by the multibranching instruction out of the entry table group.

Title: Wet type developing device for electrophotographic copier
Inventor: MACHIDA HAJIME
IPC: G03D5/06
Filed: 1979-03-13
Abstract: PURPOSE: To reduce the discharge amount of solvent vapor by supplying the developing solution of necessary amount from the inside of a developing roller.  
     CONSTITUTION: A developing roller 4 is constituted by subsequently disposing a conductive foam layer 13 and a surface layer 14 having multiple fine pores 15 and surface protrusions 16 on the outside of a porous pipe 10 which has multiple holes 12 and contains developing solution 11. As a result of this, the developing solution 11 is supplied, little by little, through the pores 12 into the voids of the conductive foam layer 13 and when the developing roller 4 is pressure-contacted to the photoreceptor 1 surface, the top ends of the surface protrusions 16 of the surface layer 14 sinks to the same height as the outside circumferential surface of the roller end edge part, by which the developing solution 11 having been contained in the conductive  foam layer 13 is pushed into the fine pores 15 and is sucked and deposited to the  charged portions of the photoreceptor 1. Hence, at the same instant of development,  squeezing is accomplished, thus the amount of the developing solution 11 depositing  on the photoreceptor 1 becomes less and the generation amount of solvent vapor is  reduced.

Title: Bias/elimination oscillation circuit for magnetic tape recording device
Inventor: HIGUCHI YOSHIO
IPC: G11B5/03
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To provide a bias/elimination oscillation circuit capable of reducing a price and preventing the distortion of a current to be eliminated by utilizing a magnetic head as an oscillation element. SOLUTION: A part of a high-frequency current flowing to an LC resonance circuit 22 is supplied to the base of a transistor T11. Accordingly, the transistor T11 is driven and an oscillation state is obtained in an oscillation circuit 24. At this time, an emitter current is supplied though a resistor R4 to a coil L1. A capacitor C12 prevents a bias current flowing from a bias B through a resistor R3 from being supplied to the LC resonance circuit 22. Thus, for erasing a video signal or an audio signal recorded in a video tape, no DC currents are supplied to a full-width erasing head 16 or an audio erasing head 18. Since no DC currents are supplied to the full-width erasing head 16 or the audio erasing head 18, no distortion occurs in a current to be eliminated.

Title: Tuning device
Inventor: WATANABE YOSHIHIKO
IPC: H04B1/18
Filed: 1979-03-12
Abstract: PURPOSE:To obtain a tuning device which can increase the sensitivity and the degree of selection as well as decrease the tracking error. CONSTITUTION:Voltage control type tuning circuit 1 includes the parallel resonance circuit consisting of inductor L1, capacitor C1 and variable capacity diode C2 each. And variable negative resistance element -R is connected in parallel to the parallel resonance circuit. Thus resonance angle frequency omegaO and acuteness Q are controlled by control voltage Vf and VR. The shift between input signal frequency and the resonance frequency of tuning circuit 1 is detected at phase detection circuit 2, and output VD is smoothed by omegaO control voltage generation circuit 3 featuring the smooth circuit constitution in order to obtain the DC voltage. And thus control voltage Vf can be obtained in the level according to the phase difference. On the other hand, output VD is smoothed in the same way via Q control voltage generation circuit 4 to be converted into the DC level. And this DC level is applied to negative resistance element 11 in the form of proper bias signal VR to secure the optional control for Q.

Title: Ink-supplying mechanism for ink jet printer
Inventor: YASUHARA MASATOSHI
IPC: B41J2/175
Filed: 1986-02-12
Abstract: PURPOSE:To prevent pressure variations in an ink-supplying system from being propagated to a nozzle part, by providing a gas chamber filled with a compressible gas at a part of an ink sub-tank and opening an ink-supplying tube into the gas chamber. CONSTITUTION:Air in a gas chamber 3 is present in an ink sub-tank 1. Therefore, in supplying an ink, the ink compresses the air when passing through the gas chamber 3, whereby variations in the pressure of the ink in a table 4 are absorbed, resulting in that the ink is supplied dropwise into the sub-tank 1, and the pressure variations are attenuated. As a result, the pressure variations are not propagated to the ink 2 in the sub-tank 1, and bad effects of the pressure variations are prevented from being produced at a tip part of a nozzle. Accordingly, an ink jet printer having high printing stability and high printing reliability can be realized.
