Abstract: PROBLEM TO BE SOLVED: To suppress the change of the shape of a pulley by the eccentric abrasion, and also retain the surface roughness of a surface and reduce loss of power, by controlling holding pressure in a previously set timing so that sliding can be applied to a transmission belt when changing a speed. SOLUTION: In a belt type continuously variable transmission 16 in which movable rotors 50, 52 are moved by a primary side hydraulic cylinder 54 and a secondary hydraulic cylinder 56, thereby V groove width of variable pulleys 40, 42, namely, the hanging diameter of a transmission belt 44 is changed, so that a transmission gear ratio is changed, oil pressure of the primary and secondary side hydraulic cylinders 54, 56 is controlled by an oil pressure control circuit 60, and this oil pressure control circuit 60 is controlled by an ECU 62. Then, when a speed is changed at the time of speed reduction, holding pressure is controlled so that sliding can be applied to the transmission belt 44.  Hereby, the whole contact surface among the transmission belt 44 and the variable pulleys 40, 42 is worn, eccentric abrasion can be prevented, and the contact width of the transmission belt 44 can be always secured in a predetermined width.

When the value of numerical data is any value excepting for '0', the dots corresponding to those numerical data are to be painted out and when the value of numerical data is '0', the dots corresponding to those numerical data are not to be painted out.  Afterwards, the graphic is overlapped with the original graphic before the execution of painting- out so that paint-out processing can be completed.

Title: Slit filter
Inventor: NARA MATSUNORI
IPC: B01D39/14
Filed: 1990-06-19
Abstract: PURPOSE:To obtain a filter reduced in pressure loss for separating minute particles, in a filter equipped with pore parts prescribing the passage of minute particles contained in a fluid by providing the pore parts in a slit-like shape. CONSTITUTION:Since minute particles approach a filter while move in a fluid, so far as the diameter in one direction of each minute particle is larger than that of each slit 3, the probability of the passage of the particle through the slit 3 is extremely low and the minute particle is actually caught only by vertical rods in the same way as a mesh. The resistance exerted on the fluid by the pore parts of the filter 1 becomes low because there are no horizontal rods and the head loss of the fluid is suppressed low. Therefore, a large amount of the fluid can be filtered within a short time and the filtering capacity of the filter is enhanced.
