Title: Magnetic disk device
Inventor: KINOSHITA AKIHIKO
IPC: G11B33/08
Filed: 1989-09-18
Abstract: PURPOSE:To decrease vibration to be generated by the access operation, etc., of a magnetic head by controlling the motion of an assembly by a vibration proof supporting member near the position of the center of gravity for the assembly in comparison with the other vibration proof supporting member. CONSTITUTION:On the lower surface of a head disk assembly HDA 1, a plug-in base 5 passing through a protecting sheet and a pair of frames 2 passing through vibration proof supporting members 3 and 4 with various hardness and an elastic member 9 are fixed by screws 7. The vibration proof supporting member 3 on the side of the center of gravity for the HDA 1 is formed by the material of the high hardness and the vibration proof supporting member 4 on the opposite side is formed by the material of the low hardness. Thus, since the side of the center of gravity is relatively braked, vibration is almost synchronized on the both side, the phase deviation of vibration acceleration for the magnetic head is prevented and the vibration can be decreased. In such a case, the difference of the hardness between the vibration proof supporting members 3 and 4 is suitably determined according to the deviating degree of the center of gravity in the HDA 1 and weight difference.

Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To correct a cold junction compensation error due to a terminal temperature distribution in a simple modification of software by adding a preliminarily set correction value for each input channel to a reference temperature of each input channel. SOLUTION: A reference temperature Tc is obtained by a cold junction compensation thermometer RJC set to a central part of a terminal 10. A cold junction temperature of each thermocouple Tc1-Tc6 is actually measured and a deviation temperature e1-e6 to the reference temperature Tc is obtained. The deviation temperature is added to the reference temperature Tc, so that a cold junction correction temperature t1-t6 for each thermocouple Tc1-Tc6 is obtained. A thermoelectromotive force Vc1-Vc6 corresponding to each cold junction correction temperature t1-t6 is obtained from a thermoelectromotive force table stored in a memory and added to a thermoelectromotive force of each measured thermocouple Tc1-Tc6, whereby a cold junction correction thermoelectromotive force V1-V6 is obtained.  Finally, the cold junction correction thermoelectromotive force V1-V6 is converted to a temperature Th1-Th6 according to the thermoelectromotive force table and displayed to a display device 21.

Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To convert a drive current to effective vibration energy by generating vibration outside by placing a vibrating body closer and colliding with a fixed portion and generating vibration and sound. SOLUTION: A vibrating body 14 is adhered to a ring-shaped flat portion 13 of a ring-shaped collision body, and a damper 11 is formed in one united body with a ring-shaped flat portion 13 and a resin.

When driving with a relatively low frequency, the ring-shaped flat portion 13 collides with a collision cover 17 through an elastic material 15 since the displacement by a coil 10 increases. Vibration created by the collision is propagated to the outside. When informing call incomming signal by a vibration, it is driven at a frequency lower than several hundreds Hz, and the collision vibration between the ring-shaped flat portion 13 and a collision cover 17 is transmitted to the outside.  Vibrating direction at this time is up-down direction only, and vibration energy can be efficiently taken out to the outside.

Filed: 1990-09-11
Abstract: PURPOSE:To prevent reduction in a transfer density caused by a change in the transfer electric field of a transfer/electrifying unit by having a control means judging the switching of a changeover switch member from the output result of a surface electric resistance detecting means. CONSTITUTION:When environmental humidity is changed, the resistance of a paper is changed, and the transfer electric field is changed. There is a correlation between the detections of the resistance of a transfer sheet and the transfer electric field. For controlling the potential of the transfer sheet 12 which forms the transfer electric field from the measurement data of a resistant value, the output of a resistant measuring circuit 15 is detected, and a control circuit 18 controls a change-over switch 17. In other words, when the environmental humidity is high, the changeover switch 17 is pushed down to the OFF-side, and when the environmental humidity is normal, the switch 17 is pushed down to the ON-side, to earth a transfer sheet guide 16. Thus, a constant transfer electric field is obtained, and a transfer image having a stabilized density is obtained.
