Title: Method of uniting spun yarn
Inventor: HACHITSUKA YUKIO
IPC: B65H51/00
Filed: 1980-12-19
Abstract: PURPOSE: To reduce the winding of spun yarn of synthetic fibers around an elongation roller in the spinning and reception process of the yarn, by moving a line of spun yarn at a prescribed speed relative to the speed of reception of other lines of spun yarn when uniting the former line of yarn with the latter lines of yarn which are moving while being coupled together.  
     CONSTITUTION: After a line 1 of spun yarn is cooled by a spinning and stopping cylinder 2, the line is supplied with oil at a roller 3 and then has its proceeding direction changed by a guide 4. Such lines 1 of spun yarn are united together through a split-type entangler 5 and a gathering guide 6. The gathered line 7 of spun yarn is then sent by a capstan roller 8 and put in a storage can 10 through dropping wheels 9. When a line 1' of spun yarn cut off due to the abnormality of a mouthpiece metal or the like is to be coupled to the gathered line 7 of spun yarn, the line 1' of yarn is passed through the entangler 5 while the line 1' is sucked and held by a suction gun 11. At that time, the speed of the line 1' of yarn is increased by an accelerator 12, if necessary, so that the speed is equalized to one and a half times or more of that of the gathered line 7 of yarn. Compressed air is supplied to the entangler 5 to couple both the lines 1', 7 to each other by the air flow.

Abstract: PURPOSE:To transmit FM signals at stable levels by imposing amplitude modulation upon a pilot signal by a low frequency signal and transmitting the resulting signal together with FM signals, and then performing AGC by a detecting signal obtained by extracting only the pilot signal. CONSTITUTION:In a pilot PL signal generator 19, an AM modulator 22 modulates the output of a high frequency oscillator 20 by the output of a low frequency oscillator 21, and its modulation output is mixed with FM signals by a mixer 3 before being transmitted.

Title: Photomagnetic recording device
Inventor: SONOBE HIROSHI
IPC: G11B19/02
Filed: 1981-11-09
Abstract: PURPOSE:To erase recording bits completely without generating any residual signal by making the scanning-directional width of a beam spot greater during erasure than during recording. CONSTITUTION:Recording bits 12 are formed on a recording medium having a magnetic film through photomagnetic effect by scanning a light beam on the medium to record and reproduce recording information, which is erased when required. In this case, the scanning-directional width DE of a beam spot 13 for erasure is made greater than the scanning-directional width DW of a beam spot 11 for recording. Therefore, even if a shift in tracking position occurs during erasure, the beam spot 13 never deviates beyond the scanning-directional width of the recording bit 12, thereby erasing recording bits 12 completely.
