Abstract: PURPOSE:To obtain the subject compound useful as an intermediate for pharmaceuticals in one step and high yield at a low cost without using expensive catalyst and oxidizing agent and preventing the by-production of industrial wastes by oxidizing a dialkyl-substituted phenols in the presence of an oxidizing agent using an inexpensive specific catalyst. CONSTITUTION:The objective compound of formula II can be produced by oxidizing a dialkyl-substituted phenol of formula I (R<1> and R<2> are alkyl or together form a carbon ring) with hydrogen peroxide in a water-soluble organic solvent (e.g. formic acid, acetic acid or acetonitrile) at a temperature between room temperature and 70 deg.C in the presence of an oxidation catalyst consisting of a heteropolyacid having phosphorus or silicon as a central element and containing molybdenum or tungsten.

Title: Anti-skid control device
Inventor: MATSUDA TOSHIROU
IPC: B60T8/172
Filed: 1979-12-26
Abstract: PURPOSE: To improve a damping control when passing through a curve route by a method wherein a damping desired value of each of left and right wheels is generated sequentially, and if the left value differs from the right one, a damping desired value of the wheel having a shorter update period is used.  
     CONSTITUTION: A signal from a wheel speed sensor 3 installed on the left and right front wheels 1R.1L is entered into a skid control circuit 8 via a desired value generation circuit 4 and an analog switch S to actuate an oil pressure adjusting device 9. A time detection circuit 5 detects a skid cycle time and an output of a comparison circuit 6, which compares with a given time, actuates the analog switch S. When the left and right cycle time is equal, an S 1  and an S 2  are turned on, and an S 3  and an S 4  are turned off, therefore, the left circuit is independent from the right circuit. When a left turning is performed and the cycle time of a left wheel becomes longer, the output of the comparison circuit 6L turns the S 2  off and turns the S 4  on, as a result, the right side signal controls the skid of both wheels.

Filed: 1983-09-14
Abstract: PURPOSE:To prevent an overcurrent from flowing at the pantograph recontacting time by throttling the gate of a thyristor rectifier by the detection of isolation of a pantograph, and gradually opening the phase of the rectifier by the detection of the recontacting. CONSTITUTION:When a counterelectromotive force of a motor and a current reference of a speed deviation are set values or higher, a motor current is zero and a voltage reference is a set value or higher, a flip-flop 28 operates to output a pantograph isolation detection signal 13.

After the counterelectromotive force 11 of a motor becomes a set value or higher by the recontact of the isolated pantograph and a time set by a monostable multivibrator 29, the flip-flop 28 is cleared. Thus, the output voltage of a rectifier gradually increases. In the drawing, a voltage reference detector is indicated by 22, a current reference detector is indicated by 23, a voltage detector is indicated by 24, a zero voltage detector is indicated by 25, and an insulating amplifier is indicated by 26.
