IPC: B60B17/00
Filed: 1984-03-19
Abstract: PURPOSE:To aim at miniaturization and improvements in durability, by making up an electric insulating material with electric insulative ceramic, in case of a device which inadditionally installs an outer wheel with the ring-shaped electric insulating material interposed in and around a wheel center being locked to an axle. CONSTITUTION:Fused electric insulative ceramic particles are sprayed to an outer circumferential surface 12 of a steel wheel center 11 and a side face 13 little to the outer circumferential surface 12. Then, these sprayed parts are finished into the specified size by means of polishing, thus an electric insulative ceramic layer 14 is made up. An outer wheel 15 is tightly attached to the wheel center 11 where this ceramic layer 14 is formed as one body by means of shrinkage fit. At this time, as for material in quality for the said ceramic layer 14, aluminum oxide and others are used. With this constitution, owing to electric insulativeness inherent in ceramic, the electric insulation between the wheel center 11 and the outer wheel 15 is thus securable, while the ceramic is inherently endowed with high hardness and heat resistance so that the outer wheel 15 is tightly attachable to the wheel center 11 as one body by means of shrinkage fit.

The result is contained in a binary coded memory 17. The image data in the memory are accumulated in a projection circuit 21, and the accumulated values, which are projected in the X and Y directions, are obtained. Then, the width of the chip in the X direction and the width of the chip in the Y direction are obtained from the distance between recessed parts (d) and compared with the widths of another chip in the two directions of X and Y and the distance between the recess parts (d), which are inputted beforehand. Thus the position of the chip is recognized. Then the difference between the specified position of the chip and the detected position of the chip is detected in the X and Y directions. In this data accumulating method, the positions of the chip is correctly recognized in a probability mode based on the accumulated data in the X and Y directions of the gap, even if the gap between the chips is small. Noises are readily removed, and erroneous recognitions are largely decreased.

Title: Liquid crystal display element
Inventor: HOSHINO TOSHIAKI
IPC: G02F1/133
Filed: 1987-03-09
Abstract: PURPOSE:To permit use of inexpensive nonpolished glass sheets by mixing adhesive particles with spacers for defining the inter-substrate spacing of a liquid crystal cell and joining two sheets of the substrates while maintaining a uniform spacing by using such particles. CONSTITUTION:The adhesive particles 13... scatter among the many spacers 7.... A liquid crystal is then injected and sealed into the gap between the substrates 1 and 2 and further, polarizers, filters, reflection plates, etc., are mounted to constitute a liquid crystal display element. The substrates of such liquid crystal display element are joined in the state of spots by the adhesive particles 13... scattering widely in many quantities in the gap between the substrates 1 and 2. The inter-substrate spacing, therefore, has the specified spacing defined by the diameter of the spacers in any positions on the inside surfaces of the substrates 1, 2. The substrates are thus forcibly deformed and the undulations are corrected by the adhesion rendered by the adhesive particles even if the unpolished glass sheets having low flatness and having the undulations are used as the substrates. The inside surfaces of the substrates are highly flattened and the inter-substrate spacing of high accuracy is assured.
