Abstract: PURPOSE:To attain to enhance reliability by eliminating ribbon feed inferiority, by confirming the pattern of the pulse generated in a sensor when a ribbon feed shaft is rotated and a slit plate traverses the sensor. CONSTITUTION:When a ribbon cassette 7 is mounted, the pawl 17d of a ribbon feed shaft 17 is inlaid with the cross hole groove 11a of a feed roller shaft 11 during several rotations and the feed roller shaft 17 is moved slightly upwardly. when the ribbon feed shaft 17 is rotated and ribbon feed is normally performed, the slits 17b of a slit plate 17a regularly passes a photointerruptor 20. Therefore, alternate regular L- and H-outputs are obtained. If regular rotary force is imparted to a ribbon feed motor 9 by any cause but the ribbon feed shaft 17 is not rotated, alternate L- and H-signals are not obtained in the photointerruptor 20. By this mechanism, the normality or abnormality of the ribbon feed system and the property of the abnormality when said feed system is abnormal can be easily known.

Each fitting 10 is formed into a strip shape and one end of its fitting is formed into a thick stepped part 11 and then, a fitting hole 12 is formed by penetrating almost a central part of the stepped part 11. At the other end of each fitting, a fitting screw 13 intersects at right angles to the thickness direction of each fitting plate and holds a position in the reverse direction to a stepped direction. Preliminary ionization density provides ionization density 11. On the other hand, a discharge current has a tendency to be concentrated on the position of each fitting screw 13 through the conductive fitting 10. These two actions make current density 12 in an actual device almost uniform spatially.

Filed: 1989-04-18
Abstract: PURPOSE:To attain the maintenance of communication by other nodes even when an optional node stops its function by arranging a function of fault detection and ring transmission line reconstitution to each node. CONSTITUTION:A fault detection section 12 monitors a token frame reached from a transmission line and detects the occurrence of a fault when no token frame is detected within a prescribed period. A fault detection section 191 in a signal transmission reception section 19 detects the occurrence of a fault when a signal from an adjacent node is lost. A beacon generating section 13 is started through the detection of a fault and a beacon frame(BF) including its own node address is sent to the transmission line. Upon the receipt from a BF of an upper stream, each node stops the transmission of the BF of its own node to transfer the BF from the upper stream. Thus, all the nodes recognize the faulty location after a prescribed time. Then a loopback device is switched in the upper and lower stream nodes of a faulty transmission line and a new loop is formed.

Filed: 1992-03-25
Abstract: PURPOSE:To reduce the burden of a motor evenly by making the amount of eccentricity from the centers of rotors of driving pins engaged with engaging projections at the initial stage of a lifting stroke of a plunger larger than the amount of eccentricity from the centers of rotation of the rotors of the driving pins engaged with the engaging projections later. CONSTITUTION:The amount of eccentricity from the centers of rotation of rotors 8, 9 of driving pins 11, 12 engaged with engaging projections 13, 14 to lift up a plunger 4 at the later stage of lifting stroke of the plunger 4 is set smaller than the amount of eccentricity of the driving pins engaged at the initial stage of the lifting stroke of the plunger. Accordingly, even at the later stage of lifting stroke of the plunger when large load is generated, it is not necessary to increase burden applied to a motor. Accordingly, the maximum torque applied to the respective pins is uniformed over the table lifting stroke of the plunger to reduce the burden of the motor evenly so as to avoid waste and reduce the sizes of the motor and a tool.

Abstract: PURPOSE: To make a coning angle variable by wind pressure working on blades and prevent excessive rotation by inclinably supporting blades of a windmill, used for a windforce heat generation device etc., and at the same time energizing the blades toward the upper course of the wind to make a slanting motion by means of an elastic body.  
     CONSTITUTION: A wind force heat generation device transmits rotation of a blade D by wind force to a main shaft 3 through hub 24 and, after its acceleration by an accelerating gear mechanism 4, transmits it to a heat generator 5 and causes the watr in the equipment 5 to generate heat, subsequently recovers this water as warm water. In this case, the blade D is the coning angle as it is reduced to small degrees of an angle of about 5° by spring tension of a coil spring 41. In case the wind speed grows more than predetermined one and wind pressure working on the blade D becomes larger than spring tension of the spring 41, the blade D is inclined to the lower course of the wind around a pin 29. At the same time, by shitting a disc 21 to the right together with a rod 19 through connecting rods 36, 31, 33 in order to compress the spring 41, the blade D is fixed at a position where the wind pressure is well balanced with tension of the spring 41.
