Title: Anti-skid control device
Inventor: WATANABE AKIRA
IPC: B60T8/1761
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of the brake control of a vehicle when a wheel rides over a step. SOLUTION: A control device starts the anti-skid control by controlling a wheel cylinder pressure adjusting means based on the comparison of the detected value of the wheel rotation acceleration/deceleration with the threshold and the comparison of the detected value of the slip ratio with the threshold in applying the brake. Tire pneumatic pressure detecting means 1a-1d to detect the tire pneumatic pressure of each wheel, and a road surface condition judging means 7 to judge the road surface condition from the detected value of the tire pneumatic pressure adjusting means are provided.  When it is judged from the road surface condition judging means that the wheel crosses over the step, the thresholds of the wheel rotation acceleration/deceleration and the slip ratio are changed to the thresholds to cross over the step different from the threshold for the flat road from the time point of judgment to the elapse of the prescribed time to make it difficult to start the anti-skid control.

Title: Data communication system
Inventor: KONISHI HIROYUKI
IPC: H04L25/49
Filed: 1989-11-10
Abstract: PURPOSE:To reduce a data recognition error at a reception side by measuring a data length and a pulse period in each pulse at the reception side, correcting the data length with a ratio of a logic value of a pulse period to a measured value and recognizing the data based on the corrected value of the data length. CONSTITUTION:A transmission side CPU 1 outputs a pulse train of a prescribed period from conventional input/output port to vary the duty of each pulse in response to a transmission data. A reception side CPU 2 uses an edge interruption port to receive the pulse train and recognizes the transmission data from the data length of each pulse. That is, suppose that a measured value tn of the data length includes an error, the error appears at the measured value Tc of the pulse period. Then TK/Tc of a theoretical value TK of the pulse period of the measured value Tc of the measured pulse period is used to correct the measured value tn of the data length into a correction value tn' without an error. Thus, the error in data recognition at the reception side is reduced.

Title: Alkylation of aromatic compound
Inventor: ENJIERU SHII
IPC: C07C15/00
Filed: 1991-11-11
Abstract: PURPOSE: To provide a process for producing an alkylated arom. compd. by contact distillation.  
     CONSTITUTION: An olefin vapor pressure may be increased while the same olefin supplying rate and ratio of the olefin to an arom. group are maintained. In one embodiment, a vapor side flow from below a catalyst and olefin supply material of a second column is thickened, and is added to an arom. replenishing flow from a reflux drum. The olefin vapor pressure at the bottom end of the first column as a catalyst bed is increased and the equiv. concn. of the olefin in a liquid phase is increased. In another embodiment of this invention, effective driving power of the reaction is increased by injecting the olefin to the different heights in the catalyst bed. The further higher catalyst bed height is necessary in the case of the injection of the additional olefin but the throughput increase at the same total olefin conversion rate is more than offsetting of the catalyst addition. The injection of the olefin supply material at the different heights is particularly useful as the required amt. of the catalyst decreases when the same olefin supply material is used dividedly to several flows.
