Patent JP-S62203559-A (JP)
Title: Power unit
Inventor: OTANI TERUAKI
IPC: H05G1/10
Filed: 1987-02-20
Abstract: PURPOSE:To suppress the overshoot of an X-ray tube voltage by switching a current from a DC power source in the duty which varies on the basis of an X-ray exposure starting signal, and supplying an inverter transformer through a smoothing circuit. CONSTITUTION:A chopping transistor 12 switches a current from a DC power source 2 in the duty responsive to the output pulse of a pulse-width modulator (PWM) 19 to generate a pulse wave. The pulse wave is converted by a smoothing circuit 17 to a DC, supplied through a choke transformer 3 to an inverter transformer 6, and an alternating voltage is generated at the secondary side of a transformer 2 by the switching operations of switching transistors 1, 1'. Here, since the output of the PWM 19 is controlled by an integrator 20 which generates an output V0 varying gradually synchronously with the X-ray exposure starting signal, a current flowing to the transformer 3 is not abruptly varied, but can suppress the overshoot of the voltage applied to an X-ray tube 10.

Title: Winding method of spiral rod for overhead wire
Inventor: YAMAMOTO KENJI
IPC: H02G7/16
Filed: 1989-02-15
Abstract: PURPOSE:To reduce audible noise or corona without sacrificing anti-wind noise effect or anti-icing effect by setting the length of spiral rod to integral multiples of winding pitch. CONSTITUTION:Winding pitch P of a spiral rod 2 to be wound around a wire 1 is set to a proper value, in due consideration of the diameter and the material of the wire 1 or the facilitation of winding work, and the length L of the spiral rod 2 is selected to be integral multiples of the pitch P. The integral multiples is determined in due consideration of storage, transportation, winding workability, and the like. Furthermore, start-of-winding end of a spiral rod is matched to the end-of-winding end of a finished spiral rod, and thereby all ends are arranged in predetermined direction, upon finish of winding work, by simply continuing the winding work. Since all ends of spiral rod are arranged at positions having lowest surface potential gradient, corona noise can be reduced without sacrifice of essential effects.

Title: Neutral position control signal forming device of head moving section
IPC: G11B7/09
Filed: 1992-02-24
Abstract: PURPOSE:To perform an offset compensation without adversely affecting neutral position control signals and to eliminate the necessity of performing an offset compensation whenever a head is exchanged. CONSTITUTION:A series circuit of resistances 31 to 33 is connected between anodes A1 and A2 of a PSD 24 and a needle of a variable resistance 32 is grounded. This series circuit is installed in the optical head side. Based on signals of S1 and S2, a subtractor 35 forms neutral position control signals. When a bobbin vibrates in a tracking direction, the signals S1 and S2 complementrily vary and control signals SC vary and the bobbin is controlled to keep a neutral position using these signals. The offset compensation of the control signals SC is performed by adjusting the variable tap position of the resistance 32. The signals S1 and S2 are complementrily adjusted to perform an offset compensation and by this compensation, the gain of the signals SC does not vary too much. No offest voltage is added and no new offset is generated when the light emission intensity of a light emitting element is varied.

IPC: B60R21/00
Filed: 1993-02-25
Abstract: PURPOSE:To enhance the alarm reliability refraining from re-emission of alarm in case the alarms emission is followed by non-sensing and then sensing is made again as long as the non-sensing time is below a certain value and the change amounts of the inter-car distance and relative speed are below the specified values gain. CONSTITUTION:A control unit 14 is fed with signals from an inter-car distance sensor 15 and a car speed sensor 16, calculates the smoothed inter-car distance and the relative speed of the car concerned with the foregoing car, determines the distance at which alarm is to be generated, and emits an alarm. If a momentary non-sensing state is generated by car motions up and down and to the left and right, followed by sensing of the foregoing car again, judgement is passed that the foregoing car is the same as before the non-sensing time as long as its duration is below a certain value and the change amounts of the inter-car distance and relative speed are below the respective specified values. The control means is constituted so that re-emission of alarm does not take place even though the foregoing car is within the distance to be alarmed, and thereby wasteful alarming is omitted.

Title: Treatment of molten blast-furnace slag
Inventor: NAKAMURA TETSUYUKI
IPC: C21B3/08
Filed: 1982-03-08
Abstract: PURPOSE:To obtain closely densed glass slag attached with no moisture, by a method wherein mass treatment is carried out by supplying molten blast-furnace slag to the clearance between a cooled moving bed and a water-cooled rotary roll and by cooling and solidifying it while rolled in a thin platy state. CONSTITUTION:Molten blast-furnace slag 7 fallen onto a moving bed 1 from a nozzle 5 installed at the bottom of molten slag gutter 4, is rolled between the moving bed 1 and the rotary roll 3. In that case, it is indirectly cooled and solidified by cooling water injected from a spray nozzle 2 installed under the moving bed 1 and by cooling water supplied to the rotary roll 3, and becomes platy slag 8 with a thickness of not more than 5mm.. This platy slag 8 breaks at the returning part of moving bed 8 end, and falls onto an outgoing conveyor 6. By this method, the warpage of platy slag is prevented; the crystallized parts due to slow cooling are eliminated, so the glass slag suitable for the raw materials of slag cement is obtained.

IPC: B65H3/52
Filed: 1983-03-07
Abstract: PURPOSE:To prevent generation of laminated paper feeding or jam of paper by a method wherein the paper feeding is effected under a stable condition at all times by a handling means consisting of the paper regulating member at the front rim of a cassette and normal turning as well as reverse turning rollers, in the paper feeding cassette or the like of an electronic photocopying machine. CONSTITUTION:The paper regulating member 7 is supported swingably by the shaft 6 of the cassette C and the front end rim thereof is a regulating part 7a regulating the movement of the paper P. The upper rim thereof is formed with a protuberance 7b and a roller 9 is supported thereby. When the paper feeding roller 1 is driven, the paper, at the uppermost position in the cassette C, is fed out. The tip ends of the papers P below the next paper P are regulated in their movements by the regulating part 7a of the regulating member 7. Accordingly, only the paper P at the uppermost position is fed out and arrives at the next handling means A, then, is sent to the conveyor roller 10 of a conveying means B under receiving the conveying force of the normal turning roller 3, which is larger than the handling force due to the pressing of the reverse turning roller 4, and is transferred into the next process. The paper P, next to the paper at the uppermost position, receives directly the handling force of the reverse turning roller 4 in the feeding direction and its advancement is precluded.
