Abstract: PURPOSE:To increase the water-repellent function and bonding function and consequently obtain a product with favorable quality by a method wherein a stock pipe is produced by covering a reinforcing thread layer produced by braiding Vinylon thread, on the peripheral surface of which fluorine-based water-repellent surface-active agent-containing covering film is provided, on the peripheral surface of a tubular inner surface rubber layer with an outer surface rubber layer and, after that, put through a mandrel in order to be cured at high temperature. CONSTITUTION:A tubular inner surface rubber layer 1 is formed. On the other hand, Vinylon threads are pretreated with a mixture of resorcin, formalin and rubber latex. A reinforcing thread layer 2 is made of the pretreated Vinylon thread and the peripheral surface of Vinylon thread is covered with surface-active agent by applying rubber paste 3, to which water- repellent surface-active agent is added and mixed with each other, onto the reinforcing thread layer 2. A stock pipe, which is mainly made of cured rubber, is produced by covering the reinforcing thread layer 2 with an outer surface rubber layer 4. Finally, the stock pipe is put through a mandrel with the desired shape so as to be directly cured in live steam. The peripheral surface of Vinylon thread is covered with fluorine-based surface-active agent so as to prevent steam from permeating the reinforcing thread layer 2 in order to cut off the contact of steam with the thread layer during curing.

Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To periodically and accurately discriminate components such as a noise other than a desired signal by discriminating the reception condition based on the state of a no-signal section during the received broadcast. SOLUTION: A control part 51 fetches the output of an A/D converter 3 and obtains the entire energy quantity in a null part and the energy distribution from the fetched data group to determine the final controlled variables of VCXOs 6 and 11. The control which the control part 51 executes by using the output of the A/D converter 3 is periodically performed by its synchronous control in response to establishment of frequency synchronism of VXCOs 6 and 11. After confirmation of a reference symbol, the control part 51 calculates the entire energy quantity and the energy distribution of a null symbol section from the output of the A/D converter 3 for the held null symbol section.  This entire energy quantity is obtained by, for example, calculating an average of the held data and the energy distribution is obtained by obtaining an average of plural sections into which the null symbol section is divided and comparing them with each other.

Title: Controller for automatic transmission
Inventor: MORISAWA KUNIO
IPC: B60W10/101
Filed: 1986-06-11
Abstract: PURPOSE:To achieve a stable slip control on a low (mu) pavement by providing means for calculating the variation rate of differential rotation between at least two wheels in four wheels and modifying the speed ratio of transmission to the incremental side when the variation rate is higher than a predetermined level. CONSTITUTION:The variation rate of the differential rotation of two wheels detected through a rotation detecting means C is calculated by a variation rate calculating means D. When the variation rate is higher than a predetermined level, the speed ratio of a transmission A being set by a speed ratio control means B is modified to the incremental side by a speed ratio modifying means E. When the condition where the slip of wheel increases is obtained based upon the variation rate of the differential rotation and employed for increasing the speed ratio, the drive torque of wheel can be reduced. Consequently, the slip of wheel can be reduced reliably even on a low (mu) pavement where the slip increasing speed is high.
