Title: Trembling-prevention device for thread-feed system
Inventor: UEHARA YASUNARI
IPC: B65H59/10
Filed: 1981-09-22
Abstract: PURPOSE:To prevent a thread from waviness and consequently curl by fitting a  suspended rod body in a thread-drawing-out hole provided above a thread-feed  body for winding the thread reeled from the thread-feed body several times  immediately on the rod body. CONSTITUTION:A thread Y drawn out from a thread-feed body 2 is wound up several times on a suspended rod body 12 inserted through a hole 11 at the top of a guide plate 10. Then, it is conducted through a gap between the hole 11 and the rod body 12, and drawn out as an arrow shows via a gap between a washer 13 and the guide plate 10. In the above-said reeling work, when curl is given to the thread Y just after reeling, this curl is moved spirally upward  along the rod body 12 together with the thread Y. Meanwhile, the frictional  force is increased in accordance with the contact length of the thread Y wound round the rod body 12 below the curl. Consequently, the curl is expanded by the  drawing-out force and the frictional force to be gradually sofened, and finally  dissolved.

Abstract: PURPOSE:To exactly detect step-out by separating the VCO from the low pass filter when the control voltage of the VCO has attained to the upper limit, fixing the voltage of the VCO, also sending out an alarm, and furthermore continuing to supervise an output of the low pass filter. CONSTITUTION:When the reference frequency fref has attained to the relation of fref>fmax/N, the output of the voltage comparator 5 repeats the operation from high to low and from low to high, and therefore, the VCO is separated from the low pass filter 2 by changing-over the switch 10, it is connected to the battery 11, the control voltage of the VCO is fixed to its upper limit, and an alarm is sent out from the AND gate 7. When said relation has become fref<fmax/N, the output voltage of the low pass filter 2 drops, the output of the comparator 5 becomes from high to low, the VCO is connected to the low pass filter by changing-over the switch 10, and the alarm of the output of the AND gate 7 is released.

Title: Recording data reproducing device
Inventor: UEDA HITOSHI
IPC: G11B20/14
Filed: 1988-06-16
Abstract: PURPOSE:To stably reproduce the recording data regardless of the difference of recording conditions like the disk sensitivity, the recording layer power, etc., by switching the delay value of the data reproducing clock between the reproduction of a prepit part and the reproduction of a recording data part. CONSTITUTION:The delay values of the data reproducing clocks supplied to an A/D converter 11 and a 4-5 demodulation circuit 12 are switched between the reproduction of a prepit part and the reproduction of a recording data part. Therefore the variance of the data recording positions can be corrected with the delay of the data reproducing clock at reproduction of data despite said variance caused to the prepit part at recording of data owing to the difference of various conditions of a disk. Thus it is possible to stably reproduce the recording data regardless of the difference of recording conditions like the disk sensitivity, the recording laser power, etc.

Title: Adaptive throughput control method
Inventor: IMAFUKU TSUTOMU
Filed: 1987-06-17
Abstract: PURPOSE:To control the throughput with a high precision by periodically calculating an actually required throughput and adding a request throughput to the current throughput at any time with respect to a call which occurs on the way of a cycle. CONSTITUTION:A current throughput integral value (e) is periodically calculated based on the just preceding data transfer quantity (b) of this cycle, and the current throughput integral value (e) and a request throughput (d) of a new call are added, and the result is compared with a convergence decision reference value, and setting of the new call is controlled if it exceeds this decision reference value, and a set throughput (g) of this call is added to the current throughput integral value to obtain a new current throughput integral value at the time of setting the new call if it does not exceed the decision reference value. Thus, the actual throughput integral value and the throughput integral value recognized by a packet exchange are not different from each other, and call setting is not controlled when a call can be set, and call setting is controlled in case of convergence, and therefore, the throughput is controlled with a high precision.

Title: Positioning device
Inventor: ICHIJIMA AKIRA
IPC: G11B17/26
Filed: 1986-06-25
Abstract: PURPOSE:To attain accurate positioning, by controlling a motor based on a difference, when it is small, between the coordinate position, to which a body is to be moved, inputted from a moving position input means, and the coordinate position of the body to be moved detected by an absolute encoder. CONSTITUTION:In a speed/position control circuit 36, the control pulse of a ROM36a, that is the control pulse to move a carriage 25 at constant speed is outputted by switching the speed/position control circuit 36, when a subtracted result between a designated position address signal Zb, and a current position address signal Za, is large. And as the carriage 25 approaches to a prescribed coordinate position to be moved, and the subtracted result between the current position address signal Za, and the designated position address signal Zb, is decreased, the signal of the subtracted result outputted from a subtractor 35 by switching a multiplexer 36b, is outputted directly, and the control pulse to move the carriage 25 decelerating it, is outputted. In such a way, the rotating speed of an AC servo motor 29 is decelerated, in other words, the moving speed of the carriage 25 is decelerated, thereby, movement to an accurate position can be attained.

Filed: 1985-07-09
Abstract: PURPOSE:To reduce the use amount of a correction tape, by reducing the feed amount of the correction tape as compared with a character width. CONSTITUTION:If the receiving data from a ETW control part 110 is correction indicating data, the master microprocessor 122 of the main controller 120 of a printer receives the data of the character to be erased transmitted suc ceedingly and operates a correction solenoid 87 to locate a correction tape 100 at an impact position and subsequently drives a printing hammer 38B to allow the same to impact a type and deletes an indicated character. When this correction operation was performed, the correction tape 10 is sent at the time of the operation of a correction solenoid 87. When the feed amount of the max. character width was set to l0, the feed amount of the correction tape 100 at this time is set to l1 1/2 the feed amount l0 or to l1 1/3 the feed amount l0. Therefore,the use amount of the correction tape is reduced to 1/2 or 1/3 as compared with such a case that he feed amount corresponding to a character width was set.

Title: Electric contact
Inventor: OBA MASATOSHI
IPC: H01H1/04
Filed: 1989-06-13
Abstract: PURPOSE:To achieve good manufacturing processability, a long life of a contact, and improve reliability of the contact by forming a coating layer of an Sb single body and an Sb-based alloy on a contact main body and thermally diffusing the coating layer into the contact main body. CONSTITUTION:An Sb single or an Sb-based alloy coating layer formed on the surface of a contact main body is thermally diffused into the contact main body. Sb is diffused into the inside of the contact main body and Ag which is composing element of the contact main body is reversely diffused to the surface. In this way, even if an organic gas is generated from a resin-made part by atmospheric temperature increase at the time of use, carbon production from the organic gas is suppressed owing to non-catalystic function of the Sb element and contact defect of the contact caused by adhering carbon is prevented. The surface of the contact main body is not a coating layer of solely Sb but contains Au and Ag which are originally components of the contact main body and diffused by heat treatment and thus good contact properties are retainined as they are.
