Title: Roller bearing
Inventor: GABELLI ANTONIO
IPC: F16C33/32
Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To provide a rolling bearing which prevents its life from being shortened by the occurrence of indentations due to the existence of foreign matters. SOLUTION: In this rolling bearing provided with an outer ring and an inner ring made of steel and forming an annular bearing space for rolling elements, at least one rolling element is made of a material harder or stiffer than the material of the other rolling elements. Any indentations, particularly projecting parts around the indentations, formed by solid contamination particles upon compression between a race surface and an rolling element of about the same hardness are compressed by a rolling element with a higher hardness, and the race surface is restored to a smooth surface 7. Only small holes 4 are left, which gives no negative influence to the running properties of the bearing. Minute quantities of lubricating oil are collected in these small holes 4, which help the lubrication of the rolling element.  The occurrence of cracks or abrasion due to stress concentration is fundamentally suppressed. The rolling bearing is rotated more quietly.

Title: Production of liquid crystal display device
Inventor: KOBAYASHI MICHIYA
IPC: G02F1/1335
Filed: 1994-12-19
Abstract: PURPOSE: To suppress the generation of the light leakage current of TFT, to surely hold the voltage impressed on liquid crystal when the TFT is off, and to improve the contrast of display images, display performance, etc., by subjecting an active layer to exposing from the rear surface of a substrate with the light shielding film patterns of a lower layer as an exposure mask for photolithography at the time of patterning the active layer. CONSTITUTION: The light shielding film 115 having a thickness of 300nm and consisting of Cr is formed on a quartz substrate 110. A first interlayer insulating film 116 consisting of SiO2 is formed on this light shielding film 115. First P-Si having the same plane shape as the plane shape of the light shielding film 115 is formed on this interlayer insulating film 116 and is patterned by the rear surface exposure using the light shielding film 115 as the mask to form the active layer. As the result, the plane shape of the active layer of TFT is so formed to nearly the same shape as the rear surface shape of the light shielding film 115 and in such a manner that the mispositioning does not arise. Light is, therefore, reflected right under the TFT and the admission of the light into the TFT is prevented. The light leak current of the TFT is thus suppressed.

Title: Position detector
Inventor: MATSUURA MITSUNORI
IPC: G01B11/00
Filed: 1990-11-20
Abstract: PURPOSE:To achieve the prevention of measuring errors associated with a temperature change by adjusting an internal resistance of a semiconductor position detector with the control of emission quantity of a light source to eliminate a temperature drift. CONSTITUTION:When an internal resistance decreases with a rise in temperature, a dark current increases and a current flowing through a common electrode 1a increases. But, in the electrode 1a, a voltage drop is caused according to a decrease in the internal resistance. The voltage drop appears as decrease in integration output of an integration circuit 7 to be inputted into a light emitting driver 8 and emission quantity of a light source 2 is adjusted with the control of the voltage drop so that the current flowing through the electrode 1a returns to the original fixed value. In other words, the emission quantity of the light source 2 is reduced and an internal resistance increases in a semiconductor position detector 1 with a decrease in the quantity of light received to stabilize the control when the internal resistance is back to the original state. As a result, the dark current settles down to a fixed value so that the current flowing through the electrode 1a is kept constant. Conversely, when the internal resistance of the element 1 increases with a drop in temperature, the quantity of emission of the light source 2 is adjusted in the direction of increasing thereby keeping the current flowing through the electrode 1a constant.
