Abstract: PURPOSE: To efficiently obtain high-purity 1,2,4,5-dimethyldiisopropylbenzene useful as an intermediate raw material for pyromellitic acid (anhydride) by alkylating p-xylene with propylene and purifying the substance from the reaction product by crystallization. CONSTITUTION: The objective compound is obtained by alkylating (B) p-xylene with (C) propylene by using (A) a supported heteropoly-acid as an alkylating catalyst prepared by making a heteropoly-acid (salt) such as 12- tungstophosphoric acid, 12-tungstosilicic acid, 12-molybdosilicic acid, 12- tungstogermanic acid or compounds obtained by replacing H of these compound with an alkali (alkaline earth) metal, a transition metal or an amine supported with a carrier such as silica gel, titania or active carbon. Preferably the reaction is carried out in the molecular ratio of the component C/B of the raw materials of 2-4 at 100-150 deg.C under 2-8kg/cm<2> and the purification by crystallization is done at -15 to 5 deg.C cooling temperature.

Patent JP-H04131917-A (JP)
Title: Servo device
Inventor: ASARI YUKIOKI
IPC: G05B13/02
Filed: 1990-09-25
Abstract: PURPOSE:To assure the excellent quick responsiveness even for a saturated operation at the time of a large amount of inputting by providing a band width switching circuit which reduces and increases the position loop band width against the small and large absolute values of a detected position error respec tively. CONSTITUTION:The absolute value of a position error 5 is converted by a detection circuit 15, and these absolute values are compared with each other by a comparator 16. Based on these comparison results, a band width switching circuit 17 switches the position loop band width omegac of a band width element 14. The width omegac is reduced against the large absolute value epsilon of the error 5 so that the system control is speeded up. Under such conditions, the width omegac is set so as to secure omegac<=2am/vm (vm: maximum velocity, am: maximum acceleration). Meanwhile the influence of saturation is reduced with the small value epsilonand therefore the circuit 17 increases the values omegac so as to attain the high follow-up performance. As a result, the quick responsiveness is assured even for a saturated operation at the time of a large amount of inputting.

Filed: 1993-10-14
Abstract: PURPOSE:To simplify the supporting structure of a herical gear shaft by reversing thrust force to be generated on the herical gear of an accelerating/ decelerating mechanism in relation to the pressing direction of a coupling. CONSTITUTION:In an accelerating/decelerating mechanism 6, when a coupling 7 is put into the engagement by control of a controller, driving force is transmitted from an intermediate shaft 14 side to be rotated at high speed to the right wheel side driving shaft 3 side. While, when a coupling 8 is put into the engagement, driving force is moved from the right wheel side driving shaft 3 side to a left wheel side driving shaft 2, thereby the driving of the right wheel becomes larger than that of the left wheel, When the couplings 7, 8 are put into the engagement, both hydraulic pressing force and thrust force to be generated on respective gears act in the axial direction and are applied to bearings 10, etc. Therefore, gears 13A to 15A and respective counter gears 18A to 18C are made herical gears, and the torsional direction of the tooth traces of respective gears are specified, so as to offset thrust force to be generated in the rotation. Accordingly, load to the bearings 10 is increased, so as to enable a device to be miniaturized and lightened.

IPC: G09G3/20
Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To optimize the image quality of a display screen by automating the phase regulation work of sampling clock signals at a high speed with a device which subjects analog video signals to digital processing and displays the images thereof. SOLUTION: An MPU 8 changes the phases of the sampling clock signals CLK by one frame each until the change of the phases attains an angle corresponding to 360 deg.C with every one frame. An image quality detecting section 7 successively fetches the digital video signals V2 and detects the max. value of the data on the absolute value of the difference between the adjacent pixels within one frame as an image quality decision data signal V7. The MPU 8 detects the max. value in all of the image quality decision data. The phase of this time is determined as the most adequate phase of the sampling clock signals CLK. The MPU 8, thereafter, periodically checks the image quality of a screen and executes the compensation of the phase of the sampling clock signals CLK in real time when a temp. drift, etc., occur.
