Title: Double action belt and manufacture thereof
Inventor: RUI DEYUPOORU
IPC: F16H9/24
Filed: 1986-05-20
Abstract: A double-action belt intended for use with speed varying devices of the type having pulleys of variable diameter is constructed of many rigid trapezoidal elements that are articulated one to another at their bases. The rigid elements all have a central opening through which an elastic member extends. The rigid elements are strung in a closed loop along the elastic member with each element being held captive by the stretchable elastic member. The sides of the rigid trapezoidal elements which are opposite the articulated base carry protruding flanges. Those protruding flanges abut when the rigid elements are pressed together and cause the central portions of contiguous rigid elements to be spaced apart to accommodate those segments of the elastic member situated between contiguous rigid elements.

Filed: 1988-05-10
Abstract: PURPOSE:To effectively enhance the breakdown strength of a MOS capacity element without complicating steps by composing to include a plurality of MOS capacity elements connected in series and inserted between two different constant potential supply lines. CONSTITUTION:Two MOS capacity elements Ca, Cb are connected in series and inserted between a power source potential supply line 1 and a ground potential supply line 2 formed on a P-type silicon substrate 3. If the two capacities Ca, Cb have the same capacity value, a potential difference to be applied between the electrodes of the capacities is 1/2 of the case of the sole capacity. Accordingly, an electric field intensity to be applied to silicon oxide films 5a, 5b becomes 1/2 of the case of the sole capacity, and an insulation-breakdown scarcely occurs. Thus. even if the films 5a, 5b are formed in the same step as that of a gate oxide film of a MOS type transistor which is further thinned, the breakdown strength of the capacities Ca, Cb are effectively increased so that its insulation breakdown scarcely occurs.

The difference in the refractive indices of the materials forming the respective layers 21, 22 is >=0.05 and the front and rear surfaces of the sheet have the surfaces which are optically flat in shape. Namely, the upper layer 22 consisting of the low-refractive material is formed on the lower layer 21 consisting of the prism sheet of the high-refractive material or the sheet having a waveform structural surface, by which the handling quality is enhanced while the light condensability is maintained. A better result is obtd. as the difference in the i-&-j refractive indices between the lower layer 21 and the upper layer 22 is larger. The refraction at the boundary between the upper and lower layers 22, 21 is small and the light condensability is poor if the difference in the refractive indices is below 0.05.
