Title: Rotary head type digital audio reproducing device
Inventor: KAWASAKI KENICHIRO
IPC: F25B5/02
Filed: 1986-11-28
Abstract: PURPOSE:To stabilize the tracking servo by using the relation of position between each track and ATF (Automatic Track Finding) so as to judge automatically a true synchronous signal and a false synchronous signal thereby controlling the synchronizing detection. CONSTITUTION:A CY output of a 6-block timer 7-23 is inputted to an AND gate 7-20 and after 6 blocks from the initial sampling signal SP1, an ATF window-off signal is outputted to the output of an OR gate 7-21 to inhibit the synchronizing detection. In this case, the final SP2 during the 6 blocks from the initial sampling signal SP1 is regarded to be correct and the sample/hold value in this case is applied actually to a capstan servo. Moreover, in setting the 6-block timer 7-23 to optional (16-12) blocks, the value subject to sample/ hold by the last sampling signal SP2 in the designated period becomes a reference voltage to control the capstan. Thus, correct tracking is obtained without malfunction.

Abstract: PROBLEM TO BE SOLVED: To realize a film for thermal stencil printing which has high sensitivity and causes little nonuniformity in perforation, by a method wherein the melting receptivity of a biaxially oriented polyester film having a melting point in a specified range is set to be in a specified range at a specified temperature. SOLUTION: A biaxially oriented polyester film of which the melting point is 140-240 deg.C is manufactured by extruding polyester being a copolymer of polyethylene terephthalate, ethylene terephthalate and ethylene isophthalate, or the like, onto a cast drum by a T-die extrusion method and by cooling it by the drum kept at a prescribed temperature. The melting resistivity of the biaxially oriented polyester film is set to be 1×10<8> -5×10<10> Ω.cm at a temperature of 280 deg.C. Since the film manufactured in this way has high sensitivity, the energy supplied to a thermal head of a printing machine can be lessened and the impairment of the thermal head can be reduced, when the film is made stencil paper.
