Filed: 1978-12-28
Abstract: PURPOSE: To obtain a copolymer with excellent compatibility with thermoplastic polymer useful for biodegradable plastic or the like by a method wherein starch is converted to meleic acid half ester and thereafter is graft-polymerized with styrene monomer by using a convertional polymerization catalyst.  
     CONSTITUTION: To starch as a main polymer, one or more monomers selected from styrene and derivative thereof alone or along with one or more other polymerizable monomers are graft-polymerized together. In this case, after starch is converted to maleic acid ester, above-described monomer components are graft-polymerized to  obtain a graft copolymer having starch as a main polymer.

Title: Chapter searching method of recording medium
Inventor: NONOMURA TADAO
IPC: G11B27/30
Filed: 1982-09-20
Abstract: PURPOSE:To decrease the chapter searching time, by performing rough and fine drives of a pickup on the basis of the chapter number and the chapter stop information. CONSTITUTION:A chapter number which is reproduced and demodulated from a disk by a decoder 4 is compared with a set chaptor number. Then a rough drive is given to a pickup 1 by a comparator 5, a sequence control circuit 7, a rough adjusting circuit 8, etc. until the coincidence is obtained from above- mentioned comparison. Furthermore the rough drive is continued, and then the pickup 1 is stopped when a chaptor stop code at the head part of the chaptor number is detected. Then the pickup 1 moves to the tip position of a set chaptor via the circuit 7 and a fine adjusting circuit 9. Therefore the chapter searching time is reduced compared with a case where the repetitive control is carried out only by a comparison between a chapter number and a set chapter number.

Filed: 1985-07-26
Abstract: PURPOSE:To enable to detect the size of a sheet to be fed without providing exclusive sheet-size detecting means, by detecting the sheet size by utilizing a paper check sensor. CONSTITUTION:A paper check sensor 10 is provided immediately after a sheet feed roll 5 of a sheet conveying path from a sheet supply unit to a transfer unit to detect the presence or absence of a sheet feeding mistake and a cassette. Write starting timing is decided by the lapse of time from when the sensor 10 detects the end of the sheet. Since the write ending timing is different with the sheet size, it is necessary to detect the size of the fed sheet. Thus, a sheet size detector which has means 22 for measuring the period from when the front end of the sheet fed through the path is detected to the time when the rear end of the sheet is detected, and means 12 for deciding the sheet size by the time measured by the means 11. Since exclusive size detecting means can be unnecessitated by utilizing the sensor, the cost can be reduced and the size can be decreased.

Title: Apparatus for making tension of ink donor film constant
Inventor: NAGATSUKA EIICHI
IPC: B41J17/02
Filed: 1984-08-06
Abstract: PURPOSE:To make it possible to perform thermal recording without obstructing the transfer of ink, by reducing a film wind-up amount by slipping a wind-up roll and a driving roll when the film wind-up amount becomes larger than a film feed-out amount. CONSTITUTION:The elastic force of a spring 25 is set to such a value that slip is generated between a wind-up roll 22 and a winding drum 24 when the tension of an ink donor film is ready to increase. The ink donor film 15 is fed out from a feed roll 26 in matching relation to a recording speed by a platen roll 20 and the wind-up roll 24 is contacted with a driving roll 24 so as to be capable of generating slip therebetween. When a film wind-up amount becomes larger than a film feed-out amount, the wind-up roll 22 and the driving roll 24 are slipped to reduce the wind-up amount. By this method, the tension of the ink donor film is always kept constant and thermal recording can be performed without obstructing the transfer of ink.
