Title: Display device
Inventor: INUBUSHI TOSHIYA
IPC: H04M1/22
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of display interference and damage of a liquid crystal display element by receiving the stress applied on a case by ribs so that the stress is not directly applied to the element. SOLUTION: The width size of a rubber sheet 7 is made shorter and the tip ends of ribs 9, which are formed on a holder 8 in a projecting manner, are formed so that the ends abut against a case 1. Thus, the load applied to the case 1 is received by the ribs 9 and no direct force is applied to a liquid crystal display element 4. Note that the sheet 7 is placed between the case 1 and the element 4 in a compressed condition so that no dust enters into the space between the element 4 and a display window and no sound is generated by an electroluminescence light 6. Thus, even though a stress is applied to the device, most of the stress is supported by the ribs 9, whose tip ends abut against the case 1, and no stress is directly applied to the element 4 through the sheet 7.

Title: Dynamic pressure fluid bearing device
Inventor: WATANABE YOSHIAKI
IPC: G03G15/04
Filed: 1988-12-05
Abstract: PURPOSE:To aim at preventing the generation of negative pressure easily generated in a low pressure region by forming a negative pressure preventing groove deeper than a dynamic pressure generating groove in the low pressure region of the pressure distribution of rough waveform generated in the axial direction by the function of the dynamic pressure generating groove formed at one part in the axial direction. CONSTITUTION:A dynamic pressure fluid bearing device is applied to an axis of rotation 1 and a sleeve 2. When the axis 1 starts its rotation, oil 5 flows along a herringbone groove, and a high pressure region is generated to this herringbone groove. On the other hand, the oil 5 flows into a part in which the herringbone groove is not formed so as to become a low pressure region. But a negative pressure preventing groove 21 deeper than the dynamic pressure generating groove is formed in this low pressure region, and oil circulation is generated inside the negative preventing groove 21. Even in case the pressure continues to be lowered in the low pressure region, the internal pressure of the negative pressure preventing groove is lowered uniformly by this circulation, so that the pressure is prevented from being lowered down to the generation of the negative pressure. The generation of the negative pressure is thus prevented.
