Title: Image forming device
Inventor: MOTOHASHI TOSHIAKI
IPC: G03G15/01
Filed: 1994-08-26
Abstract: PURPOSE: To improve an unstable toner holding state, to prevent toner from being scattered toward a transfer paper, to make electrical contact force among the toner strong and to prevent the toner from being peeled in the intermediate part of a toner layer by electrostatically charging the toner on an intermediate transfer belt before it is transferred on the transfer paper. CONSTITUTION: This device is provided with a pretransfer charger 50 consisting of a corona electric discharger as a means for electrostatically charging the toner on the intermediate transfer belt 19 before the transfer paper 211 enters a transfer bias roller 23-1. The electric discharge of a toner image formed on the belt 19 is executed by the charger 50 and the toner is electrostatically charged further. Then, the electrical contact force among the toner is made strong. Thus, since the electrical contact force among the toner is made strong even in the case that flocculation is caused among the toner because a bias whose polarity is reverse to the toner is impressed and the paper 26 is pressured by the roller 23-1 when a transfer action is executed on the paper 24, middle omission of a character part is not caused at a character part.

Title: Operation control device for plural unmanned vehicle
Inventor: WATABE TATSUYA
IPC: G05D1/02
Filed: 1988-08-12
Abstract: PURPOSE:To make it possible to always collectively change the speeds of all vehicles even at the time of starting, stopping, accelerating, or decelerating a motor by controlling the motor by a difference between both frequency levels when a command speed is different from a practical rotational speed. CONSTITUTION:A comparing/subtracting means 21 compares a signal detected by a signal detecting means 8 with a signal outputted from a signal generating means 17, and when the frequency levels of both the signals are sharply different from each other, i.e. when the command speed of a speed command signal is sharply different from the practical rotational speed obtained from a rotational driving means 6, finds out the difference between both the frequency levels. A correcting/adding means 15 adds a signal outputted from the means 21 to a driving signal outputted from a signal synthesizing means 13 to find out the correction value of the driving signal and drives a rotational driving means 6 by a corrected driving signal based upon the correction value. Consequently, the speeds of the whole vehicles can be always collectively changed even at the time of starting, stopping, accelerating, or decelerating the vehicles.

Abstract: PURPOSE:To satisfactorily control a PS motor, by constituting a detector for detecting steering torque with a detecting section disposed between first and second shaft sections of a steering shaft which are divided in three shaft parts and a detecting section disposed between second and third shaft sections. CONSTITUTION:When a steering wheel is turned rightward, a twist is brought about between first and second steering shaft sections, resulting in the movement of a cylinder 17 in the direction C to close a switch 20.

If the steering torque applied to the steering wheel 2 is further increased, an arm 1a is made into contact and engaged with a notch section 3a so that the first and second steering sections are rotated, integrally together. Then, a twist is brought about between second and third shaft sections 3, 8, resulting in detection of a torque value by a torque detecting section 9. In accordance with the detected torque value a motor 5 is driven to generate a required auxiliary torque.

Filed: 1993-07-23
Abstract: PURPOSE:To clearly visualize gas flow. CONSTITUTION:Pure water mist is mixed into the gas flow to be visualized. Beam-like laser light including wavelength in a specific visible light region is repetitively scanned from a laser oscillator 3 to be applied to the gas flow, and scattered light generated at this time from the pure water mist is recognized through an optical filter having relatively high transmissivity only for the range of laser light oscillation wavelength.

Filed: 1992-07-30
Abstract: PURPOSE:To improve safety by setting an insulating medium to a predetermined value or less of vacuum, and evacuating in vacuum it when the vacuum degree in a metal vessel exceeds the predetermined value. CONSTITUTION:A vacuum pump 10 is connected to a vessel 1 of a power receiving facility through a stop valve 9. Further, a vacuum meter 11 for monitoring vacuum degree in the vessel 1 is provided. The pump 10 is operated together with the valve 9 when vacuum degree measured by the meter 11 is reduced. That is, when a pressure measured by the meter 11 becomes 10<-2>Pa or more, a power source of the pump 10 is turned ON, and the pump 10 is operated. Then, the valve 9 is closed, and the vessel 1 of the facility is evacuated in vacuum. When a pressure of the meter 11 becomes 10<-2>Pa or less, the valve 9 is closed, and the pump 10 is stopped. Thus, safety can be enhanced while maintaining a dielectric strength equivalent to SF6 gas.

Abstract: PURPOSE:To obtain a thermal cell which produces that heat and generates electric power with high reliability owing to an igniter by which flare is produced when impact force is applied to it by using a sealing glass terminal which works both as an impact core and as a sealing member. CONSTITUTION:A sealing glass terminal 7 consists of an outer metallic ring 7a, a glass member 7b and an impact core bar 7c. A monitor guide 8 causes the core bar 7c to strike the center of an impact-type ingniter 1. The flare produced by the igniter 1 is introduced through a fire introduction hole 9. The sealing glass terminal 7 is fused to an exterior lid 5 by welding, soldering or similar means. A metallic fixture 4 in which the igniter 1 is placed and the exterior lid 5 are also unified, thereby making an impact-type ignition device (A). When impact force is applied to the device (A) in the direction indicated by arrow (F), the core bar 7c is pushed and vigorously strike the igniter 1 which then produces flare. The thus produced flare is then introduced into the fire introduction hole 15 of th stacked body through the fire introduction hole 9 to cause the heating agent 11 of each layer to catch fire successively, thereby increasing the temperature of the entire thermal cell and melting the electrolyte layer.

Filed: 1983-10-28
Abstract: PURPOSE:To reduce the resonance with a mechanism system by generating a pulsating voltage when a target position and a present position become equal to each other. CONSTITUTION:The output pulse 8' of a position detector 8 is applied to a present position counter 11, and the present position 11' of a motor shaft is outputted. The position 11' is compared by a comparator 13 with a target position 12' stored in a target position memory 12, and a signal 13' is outputted when the position 11' and the target position 12' become equal. At this time a pulse generator 14 forms a pulse output 14' having arbitrary width and amplitude, and applies it to an addition/subtraction unit 10. Thus, the target position which is empirically obtained by a human being in advance is stored in the memory 12, and the pulse current having arbitrary width and amplitude always at the prescribed position in the repeated operation is applied to a DC motor 5.

IPC: G03G9/107
Filed: 1994-08-29
Abstract: PURPOSE: To effectively prevent the falling of a surface treating agent even under mechanical stress by cleaning, etc., and to effectively perform recycling development by surface-treating resin particles by mixing with a fine particle- shaped surface treating agent under the action of a mechanical shock so that the surface treating agent is embedded in the surfaces of the resin particles. CONSTITUTION: Resin particles are surface-treated by mixing with a fine particle-shaped surface treating agent under the action of a mechanical shock so that the surface treating agent is embedded in the surfaces of the resin particles. The degree of embedding of the surface treating agent is preferably regulated so as to attain 50 to 90wt.% rate (R) of sticking of the surface treating agent defined by the equation R=(A/B)×100 (where A is the amt. of the surface treating agent stuck to the resultant toner after mixing with a carrier and B is the amt. of the surface treating agent stuck to the toner before mixing with the carrier). In the case of <50wt.% rate, it becomes difficult to effectively prevent the deterioration of the physical properties of the toner. In the case of >90wt.% rate, the flowability of the toner is made unsatisfactory.
