Patent JP-S6445652-A (JP)
Title: Impact-type dot printing head
Inventor: NAKAJIMA NORIO
IPC: B41J2/235
Filed: 1987-08-17
Abstract: PURPOSE:To detect the protrusion and return timing of printing wire and thereby prevent any trouble such as hooking of ink ribbon by providing an electrode sheet consisting of an insulative membrane, a conductive membrane and a protective membrane which is fixed over the side of a core tip of a magnet which comes into contact with a leaf spring when it is attracted. CONSTITUTION:First, a leaf spring 16 is attracted to a core 12 by the magnetic flux of a permanent magnet 11, and the leaf spring 16 and a conductive membrane 32 are set in contact with each other. Consequently, an input (-) on a comparator 40-1 of a detection part is at low level, while its output is at high level. A low level output is applied to the control part of a printer from an output terminal O1 through an inverter 41-1, and this is recognized as a continuity state. Then, a coil 13 is energized and the leaf spring 16 is released by exciting a magnetic flux which cancels the magnetic flux of the permanent magnet 11. This results in the protrusion of printing wire 18 and the subsequent pressing of ink ribbon and a printing medium by the printing wire for printing. At that time, the leaf spring 16 is insulated from the conductive membrane 32, and a high level output is applied to the control part from the output terminal O1.

Title: Method for skin pass rolling in continuous manufacturing line
Inventor: MOCHIZUKI SAKAE
IPC: B21B1/22
Filed: 1987-08-17
Abstract: PURPOSE:To uniformize the wear of work rolls and to also uniformize the surface roughness of a steel strip by skin pass rolling a preceding steel strip with the strip moved in the width direction by at least a moving amount being equal to a width difference between the preceding and succeeding strips at the case that the succeeding strip is wider than the preceding strip. CONSTITUTION:At the time of skin pass rolling of steel strips whose width are different, respective moving amounts of respective strips in the width direction are calculated based on a passage schedule of the strips. Then, in passage, a preset computer 6 calculates momentary moving target values based on length measuring pulse signals of a pulse generator 9 and inputs calculated values to a steering controller 5C. The controller 5C actuates a steering device 5A based on signals of a strip position detector 5B so that a steel strip 10 has a moving target value at the outlet side of the steering device 5A. The strip 10 is moved by an amount larger than a width difference in the width direction and is subjected to skin pass rolling. Hence, wear in the width direction of work rolls 1A, 1B is uniformized.

Title: Automatic sheet feeder
Inventor: FUJIMOTO SAKAE
IPC: B65H3/52
Filed: 1983-10-31
Abstract: PURPOSE:To permit even a curled sheet to be fed favorably by installing a tension plate onto the back surface of a separating member whose freed edge press- contacts with a separating roller which feeds sheets one by one in separated state and providing the back pressure for pressing the separating member onto the separating roller. CONSTITUTION:A separating roller 3 is installed onto the top edge part of a sheet loading base 1, and a part of the peripheral surface of the separating roller 3 projects from the sheet loading surface. The free edge part 9 of a separating member 8 is brought into contact with the peripheral surface 7 of the projection part of the separating roller 3. In this case, a tension plate 10 is installed onto the back surface of the separating member 8, and the respective base edge parts 11 and 12 of the both 8 and 10 are fixed onto a bracket 13. The tension plate 10 is formed to have a strong spring performance by using a steel thin plate, etc. When a sheet bundle S whose top edge SA is upwardly curled in loaded onto the sheet loading base 1, the contact area between the top edge SA and the peripheral surface of the separating roller 3 is reduced. However, since the tension plate 10 provides a back pressure onto the separating member 8, the press-contact force necessary for feed can be obtained.

Title: Liquid level indicator for vehicle
Inventor: KOBAYASHI MASAYUKI
IPC: G01B7/00
Filed: 1983-10-31
Abstract: PURPOSE:To hold an indicating state basing on a variation state of a liquid level by generating a signal only for a prescribed time required for a convergence only when a transient variation state of a detecting signal exceeds a prescribed allowable range, and cutting off a power supply to an indicating mechanism from a DC power source. CONSTITUTION:When an ignition switch IG is closed, in case when a detecting voltage Va generated from a liquid level detecting circuit 20 is stable, a monostable multivibrator 40 does not generate a high level signal due to a relation to a differential voltage generated from a differentiation circuit 30, and a transistor 51 conducts. Also, a stable composite magnetic field is generated, and a needle is also stabilized by controlling a inflow current to a coil due to a relation to a current flowing into a resistance 66 by an operation of a differential amplifier 63 and a transistor 67 to the voltage Va and a voltage Vb. Also, when the liquid level changes suddenly and the voltage Va changes suddenly, a high level signal is generated, the transistor 51 becomes non-conducting, a driving force from a driving part 10 is eliminated, and the needle holds its immediately previous position.
