Title: Pen lifting mechanism in automatic line making device
Inventor: KIYOZAWA TORU
IPC: B43L13/00
Filed: 1991-06-26
Abstract: PURPOSE:To prevent the jumping up of a pen arm, allow the pen arm to move following the downward movement of a pen-up plate and reduce the level of noises emitting from pen arm collision. CONSTITUTION:A pen arm 13 is pressed against a pen-up plate 26 by the pressing action of a pen arm bar 31 and moved in the as-pressed condition following the up-and-down motion of the pen-up plate 26. The pressing action of the pen arm bar 31 is set at such a force as to allow the pen arm 13 to move downwards in conjunction with the pen-up plate 26 when a line making surface is set in a standing position. Due to the repelling magnetic force between the pen arm 13 and each of the pen-up plate 26 and the pen arm bar 31, the level of the noises emitting from the collision with one another during the pen up-and- down motion is reduced. The friction between the pen arm 13 and the pen arm bar 31 during the pen down-motion is reduced by the magnetic repelling force therebetween, whereby the pen arm 13 can be driven lightly and smoothly in both the longitudinal and lateral directions.

Abstract: PURPOSE: To reduce construction costs by carrying a number of facings by using a ceiling facing elevating/carrying means arranged at a predetermined location directly below a ceiling, sequentially pressing them along a facing installation guide rail, and stretching them on the entire surface of the ceiling. CONSTITUTION: A ceiling facing 1 is movably hung on a joint rail 2' of a ceiling facing 1 elevating/carrying means R arranged directly below a ceiling, and hoisted to the location of a ceiling.

Title: Compensating detector
Inventor: TOMISATO TETSUO
IPC: H03D1/10
Filed: 1989-07-14
Abstract: PURPOSE:To improve the temperature characteristic and the input and output voltage linearly of a detecting circuit by feeding back the output of an operational amplifier to the input side through a circuit having the same constitution as the detecting circuit where the detecting circuit is connected to the input side of the operational amplifier. CONSTITUTION:A high frequency input forming voltage V1 is detected by a diode D1 to flow a current i1 to the input terminal of an operational amplifier OP. On the other hand when a feedback current i2 flow from the output terminal of the operational amplifier OP through the feedback circuit, i1+i2=0 is true because currents are balanced between input terminals of the operational amplifier OP. When diodes D1 and D2 have characteristics equalized and resistors R1 and R2 have the same form and the same resistance value (that is, R1=R2 is true), impedance Z1 and Z2 of the detecting circuit are equal regardless of the change of a temperature (t) or an applied voltage (v). Thus, the change due to the ambient temperature and the linearly dependent upon the input voltage are improved.

Title: Low speed control device of engine
Inventor: AKIMOTO KAZUOMI
IPC: F02M3/09
Filed: 1982-10-18
Abstract: PURPOSE:To simply and surely adjust the enrichment of mixture so that the mixture is continuously and stably fed to an intake-air passage, by independently controlling the volume of air and the volume of mixture from each other in accordance with drive current from an electronic control device. CONSTITUTION:When an ignition switch 33 is turned on, drive current in accordance with the temperature of an engine is fed. Upon low temperature operation, such a condition is obtained that a first control valve 12 is closed for a relatively long time to decrease the volume of bleed air while a second control valve is opened to a large opening degree to feed a high rich mixture in a large volume. As the temperature is more and more raised, the opening time of the first control valve is made shorter and shorter while the opening degree of the second control valve 18 is made smaller and smaller so that the enrichment and volume of mixture in accordance with the temperature of the engine may be fed to an intake-air passage 24. When the engine is subjected to cranking, a mixture of enrichment in accordance with the temperature of the engine is fed. After completion of combustion, the mixture is compensated to be adapted to a mixture of engine warm-up in accordance with an input signal from a vacuum sensor 28, and after engine warm-up, is compensated to be adapted to a mixture of idling.

Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To stably perform the switching control of a positive-side converter and a negative-side converter without losing the vector of an actual current even when the sudden change of a load is brought about. SOLUTION: Vector control parts 17 to 22 control the torque component current Iqf and the magnetic flux component current Idf of AC currents I1u, I1v, I1w which are supplied to an AC motor 4 from converters 3a, 3b, 3c on the basis of a torque current standard Iq* and a magnetic flux current standard Id*, and when the polarity of the torque current standard Iq* is inverted, a torque current standard rate-of-change limiting means outputs a correction torque current standard Iqc* limited to a predetermined rate of change within a predetermined range including a zero.  Therefore, even when a load is suddenly changed, the correction torque current standard Iqc* is not rapidly changed in the vicinity of a zero to suppress the rapid change of a current standard phase and to prevent all phase currents from becoming a zero, thereby stably performing the switching of the positive-side and the negative-side converters without losing a current vector.

Abstract: PURPOSE:To adequately control hole openability by driving of a steel rod at the time of executing preopening of a mud material by determining the time since the mud material is packed into a tap hole a before a mud gun is removed to the specific conditions. CONSTITUTION:The mud material 5 is press fitted and packed by means of the mud gun 6 into the tap hole 2 penetrating the wall 1 of a blast furnace. The mud gun 6 is removed in the stage when firing of the mud material 5 progresses to some extent. The steel rod is driven into the mud material 5 and while the steel rod is held penetrated therein, the steel rod is held before the next tapping is started. The pressing time by the mud gun 6 of this time since the mud material 5 is packed into the tap hole 2 before the mud gun 6 is removed is determined according to a relation between the predetermined pressuring pressure on the mud material 5/the extruded amt. of the mud material and the pressing time by the mud gun 6. As a result, the excess and deficiency of the firing according to a change in the amt. of pressurization on the packed mud material 5 are estimated by the press fitting condition of the mud material 5. The firing of the mud material is thus kept constant.

Abstract: PURPOSE:To reduce the required space of a conveyor in a small scale by moving the side plate member of a material conveyor toward the central direction of material holding means to receive the material when the holding means holds one stacked material and then transferring it to next step. CONSTITUTION:When material holding means 2 holds only one material M to move upward it in the prescribed stroke, a material conveyor 3 moves two side plate members 3a from both sides toward the central direction of the means 2, and when the end of the material M' is disposed on a moving tool 3b, the means stops moving. At this time, the means 2 releases holding of the material M', and transfer the material M' to the next step by suitable means. The transferring means employs a belt or roller members for the tool 3b to drive itself. Since the holding means and the conveyor for feeding it to the next step are individually arranged in a simple structure, they can be simplified to reduce the required space.
