Title: Winding of film
Inventor: MORITA AKIRA
IPC: B65H18/00
Filed: 1985-01-31
Abstract: PURPOSE:To improve the quality of a roll formed when a polyester film used for a magnetic tape or the like is wound around a plastic core with a given surface roughness under the presence of aqueous solution including a surface-active agent. CONSTITUTION:When a film is wound by a winder to form a roll, the density of a surface-active agent may be appropriately selected according to the kind of the surface-active agent, the property of the film and the like. The aqueous solution of density 0.1-10% impregnated in a sponge or a lint fabric is applied to a core used. Then the film is set to the surface of the core applied with the aqueous solution to be sticked to the surface and begins to be wound. The core made of a plastic has a turning surface roughness of 1-6mum. When a polyester film with smooth surfaces is wound around the core to form a commercial roll product, none of a pit is found on the film surfaces of outer and intermediate roll portions and minute pits are found only on the film surfaces of the innermost portion of the roll.

Title: Switching power source apparatus
Inventor: UMETSU FUMIKAZU
IPC: H02M7/12
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To provide a switching power source apparatus which controls a rush current and assures high efficiency. SOLUTION: During the period where an AC power source VAC turns on and a switching element Q11 is on, a current i2 due to the rectified output of a diode bridge circuit D11 flows. In this case, a current i1 from the positive output terminal of D11 flows. With this current i1 , an energy is accumulated in the capacitor C11 and an energy is temporarily accumulated (held) in a choke coil L11. During the period where Q11 is OFF, the energy temporarily accumulated in the L11 generates a reverse electromotive force and flows as i3 and charges C11. That is, the energy temporarily accumulated in the L11 is recovered in the C11 to repeat the switching operation. Thereby, the energy is accumulated (C11 is charged). This accumulated energy provides the smoothed full-wave rectified output. Thereby, it is no longer required to use a rush current preventing circuit and an active filter circuit.

Title: Information recording and reproducing device
Inventor: SHIBATA TAKEHIKO
IPC: G11B20/14
Filed: 1985-01-30
Abstract: PURPOSE:To control easily recording or reproduction, also to make a recording density high, and to shorten an access time by making a recording or reproducing speed different in an area consisting of plural tracks and an area which is different from said area. CONSTITUTION:A reproducing clock generator 10 is constituted with so called a P.L.L circuit, but recording/reproducing clock rates of the innermost peripheral track group T4 and the outermost peripheral track group T1 are are separated by about two times, and in a usual P.L.L circuit,it is difficult to lock stably to an object frequency in this range. Therefore, when an address is designated at the time of the reproduction, a frequency selecting signal corresponding to the address is generated from a controller 1 in the same way as the time of recording, any one frequency among f1-f4 is outputted as the comparison frequency of a reproducing clock generator 10, to the reproducing clock generator 10 through an AND gate 4 and an OR gate 5, and the center frequency of the PLL is varied suitably. By a reproducing clock which is obtained in such a way, a binary-coding output signal outputted from a comparator 9 is sampled by a demodulator 11, by which a recording data bit train (...1,1,0,1...) is obtained.
