Title: Electrostatic recorder
Inventor: WATANABE MASANOBU
IPC: G03G15/05
Filed: 1989-10-26
Abstract: PURPOSE:To prevent a transfer electrode from being stained by making the potential of a bias voltage applied to the transfer electrode equivalent to that of a bias voltage applied to a developer carrier when a recording medium is not present between the developer carrier and the transfer electrode. CONSTITUTION:An ion flow moving from an ion supplying source 6 to a developer thin layer is modulated according to an image signal by applying a voltage, which corresponds to the image signal, to an ion flow modulating means 9 by means of a control power source 10; consequently the ion flow reaches the developer thin layer. For a formed electrostatic latent image, developer is transferred on the recording medium by applying a bias voltage by means of a bias power source 7, when a recording medium is present between the developer carrier 1 and the transfer electrode 11. The potential of the developer carrier and that of the transfer electrode are made equivalent to each other by the use of a switch 12, when a recording medium is not present between the developer carrier 1 and the transfer electrode 11. By controlling the applying of a bias voltage in such a manner, developer is not splashed from the developer carrier 1 to the transfer electrode 11, and therefore the electrode 11 can be prevented from being stained.

Title: Method and apparatus for extracting naphthalene
Inventor: KOBAYASHI MASAJI
IPC: C07C7/04
Filed: 1988-11-02
Abstract: PURPOSE:To provide the objective substance in a good yield without clogging a piping by employing an extraction device equipped with a temperature-detector and a control valve interlocking therewith when an absorbing oil subjected to the absorption of a cake furnace gas is distilled to give naphthalene and a crude light oil. CONSTITUTION:Naphthalene and benzene contained in a coke furnace gas are absorbed in an absorbing oil and subsequently fed in a distillation tower 32 through a pipe 35. The naphthalene distilled out on a naphthalene-extracting stage is stored in a tank 34 through an extraction piping 37 and a control valve 40. When the measuring temperature of a temperature detector 38 exceeds 170 deg.C in this process, a temperature indication controller 42 sends a signal for reducing the opening degree of the control valve 40 to the control valve. When the opening degree of the control valve 40 is thus reduced, the stream of steam blown into the tower is disturbed to lower the temperature of the extraction stage to <=170 deg.C. When the temperature reaches a temperature of <160 deg.C, a signal for increasing the opening degree of the control valve 40 is sent to improve the stream of the steam, thereby raising the temperature. The control of the temperature to 160-170 deg.C permits the effective separation of the objective substance.

Filed: 1990-10-16
Abstract: PURPOSE:To attain stable AFC without locking an adjacent channel at channel selection by using a bridged T-shape attenuation trap so as to attenuate a video carrier of an upper adjacent channel. CONSTITUTION:A tuner 1 selects an RF TV signal, a signal subject to frequency conversion in the tuner 1 is distributed to an output and an IF output of a terminal equipment and an IF signal controls the AGC/AFC. A bridged T-shape attenuator trap 4 is adjusted so that a video signal carrier of an upper adjacent channel of a selected channel of a signal outputted from an IF output terminal is attenuated. Thus, the signal passing through the trap passes through a coupling capacitor 3 and enters a demodulation IC2. A control voltage is applied from the demodulation IC2 to AGC/AFC terminals 5, 6 of the tuner 1. Thus, the AFC locking is implemented stably.

Title: Method and apparatus for correcting printing density of serial printer
Inventor: FUJIMORI YOSHIHISA
IPC: B41J2/365
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To improve a cyclic density irregularity and improve recording quality, by restricting in a simple method a decrease of a recording density at both end parts of a recording head, e.g. a thermal head, having a plurality of recording elements arranged in a row. SOLUTION: Among (n) recording elements arranged in a row, n-(i+j) recording elements at a central part excluding (i) elements at one end of the row and (j) elements at the other end are driven as recording elements generating color-developed dots corresponding to a recording image. All or a part of the (i) and (j) recording elements are driven as recording elements not generating color-developed dots with a predetermined energy. In other words, the (i+j) recording elements at both ends do not directly contribute to recording of the image and rather function to suppress a temperature decrease (i.e., decrease in recording density) at both end parts of the central n-(i+j) recording elements with a relatively weak generation of heat.
