Title: Media clamp structure
Inventor: OKADA TADASHI
IPC: G11B17/028
Filed: 1990-07-30
Abstract: PURPOSE:To reduce the temperature change of the adsorbing force at the position of a medium and to attain the use of an inexpensive magnet by attaching a material having a positive thermal expansion coefficient to a rotor via an attachment member stuck to the rotor and setting an adsorbing magnet opposite to an adsorbed part of the medium with a space that is reduced with the rise of temperature. CONSTITUTION:A medium M is put on a medium mounting surface 2 of a rotor 1 and held by an adsorbing magnet 14. An attachment member 17 expands with the rise of temperature, and the space secured between the adsorbed part of the medium M and the magnet 14 is reduced. The magnetic force of the magnet 14 reduces with the rise of temperature. However the adsorbing force affecting the adsorbed part of the medium M that is caused by the reduction of the space can be compensated and has no big change. As a result, the medium M is surely held at all times and the use of the magnet 14 which does not have so high temperature characteristic can be applied.

Filed: 1989-08-04
Abstract: PURPOSE:To increase tensile strength and enlarge a rotation angle by allowing the spherical internal surface of a pair of side covers fixed to each yoke to slidingly touch two spherical external surface of a center cover for supporting trunnions. CONSTITUTION:A cylindrical intermediate joint member 1 is provided with trunnions 2 and 3 orthogonally supporting each other and freely rotatable yokes 4 and 5. A ring-like center cover 7 is composed of cover component members 9 and 10 having spherical external surfaces 7a and 7b and the intermediate member 1 to which the component members 9 and 10 are fixed by screws. A pair of right and left side section covers 21 and 22 having the spherical internal surfaces 21a and 22a slidingly touching to the spherical external surfaces 7a and 7b are fixed to the yokes 4 and 5 by screws. Since this prevents the trunnions of both yokes from interfering, interference preventive recesses are eliminated resulting in the increase in tensile strength. In addition, the rotation angle of the side section covers become large for enlarging the rotation angle of the yokes.

Abstract: PURPOSE:To increase adhesion strength between a magnetic layer and a supporting body, and to improve durability and reliability by specifying the average value of surface roughness for any ten small areas in a 10 micron X10 micron area arbitrarily selected in the surface of the supporting body. CONSTITUTION:The average value of surface roughness (Ra)* for any ten small areas in a 10 micron X 10 micron area arbitrarily selected in the surface of the supporting body is specified to >=0.03mu and to <=20% of the film thickness of the magnetic layer.

IPC: H03M1/10
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To adjust DC offsets without damaging the effect of a DC dither by providing a current source circuit provided with plural current sources for offset adjustment in an output buffer. SOLUTION: In order to adjust the DC offset in the output buffer 4, an inverted input terminal N is provided with the current source circuit 9 for switching and connecting the plural current sources. The output terminal of a comparator 6 is provided with an inversion detection circuit 10 for detecting the inversion of the output and outputting adjustment end signals. When the output terminal potential of the output buffer 4 becomes lower than a reference potential VREF, the output of the comparator 6 is inverted and the offset adjustment is completed. When the inversion detection circuit 10 outputs the offset adjustment end signals, the signals are supplied to the PE terminal of a counter 7 and output data at the time are latched. Thereafter, the current source circuit 9 is held in the state of selecting the current source optimum for the offset adjustment.  In such a manner, the offset adjustment is performed only in an output buffer stage without depending on feedback to an input stage.

Abstract: PROBLEM TO BE SOLVED: To provide a print data spool device which can spool the received print data even if the space area becomes short in its own spool memory. SOLUTION: When a printer 131 is unable is store all print data received from a print data generation device 12 in a spool memory of its own device, the print data unable to be stored are transferred to another printer 132 , etc., via a network 11 and virtually spooled in the spool memory of the printer 132 , etc. The printer 131 monitors whether a space area is secured in its own spool memory in accordance with the print progress. When a necessary space area is secured in the spool memory of the printer 131 , the printer 131 calls back the print data which are virtually spooled in the printer 132 , etc., via the network 11.
