Patent EP-0320936-A3 (EP)
IPC: B01J29/70
Filed: 1988-12-15
Abstract: A very simple process for preparing p-ethylphenol is 
disclosed. It is only necessary to contact phenol with an 
ethylating agent in vapor phase in the presence of a specific 
catalyst. The catalyst can be obtained by incorporating one 
or more alkoxysilanes to a crystalline aluminosilicate with a 
constraint index of 1 - 15 having a silica/alumina molar ratio 
of 20 - 400, wherein the amount of said alkoxysilanes to be 
incorporated is not less than 1.4 wt% calculated as silicon 
based on the amount of said crystalline aluminosilicate. 
Because the specified catalyst has the narrowed or restricted 
entrances of the micro pores of the crystalline 
aluminosilicate by the alkoxysilane treatment, it is possible 
to prepare p-ethylphenol in a high selectivity. The product 
contains only a very small amount of m-ethylphenol. The p-­
ethylphenol product obtained by the process of the present 
invention can be employed directly as raw materials for 
practical uses such as synthetic resins and antioxidants 
without m-ethylphenol elimination procedure.

Abstract: An electronic blackboard wherein a multiplicity of 
heads for reading and writing storage data in relation to 
memories are disposed lengthwise and breadthwise on the 
surface of a board so that data can be read from and written 
into the memories on the board surface. Also disclosed is 
an electronic blackboard system which comprises input/output 
control means for controlling a storage data input/output 
operation in which heads which are disposed on the surface 
of a board are sequentially scanned to read or write storage 
data and data processing means for processing storage data, 
whereby storage data relative to a memory which is stuck on 
the board surface is read or written with a predetermined 
relationship between the head position and the storage data.  
     By virtue of the above described arrangement, when a 
memory is stuck on the board surface, storage data is read 
from or written into the memory by means of the 
corresponding head through the input/output control means, 
and the read/write data is processed in the data processing 
means. Accordingly, it is possible to store data into 
memories on the board, read the data from the memories, and 
process data corresponding to the position of each memory 
stuck to the board surface.

Abstract: A circuit which responds to the application of a pulse to its 
input (6) by generating a pulse at its output (3), the output pulse 
having a minimum duration T and being extended by the remaining 
length of the input pulse should the input pulse be still present at 
the end of the time T, comprises a pair of semiconductor switches 
(1,2) connecting the output (3) to points (5,4) carrying respective 
logic levels. The input pulse closes the first switch (1) and also 
inhibits a gate circuit (9). The resulting logic level on the 
output (3) closes the second switch (2) after delay by T in a delay 
circuit (13) and transmission through the gate circuit (9), thereby 
restoring the original logic level. The instant when this occurs 
coincides with the presence of the delayed output pulse at the 
output (14) of the delay circuit and the absence of the pulse at the 
arrangement input (6). A hold circuit circuit (15) may be provided 
for holding the logic level currently present at the output (3). 
The circuit may be used as an equalisation pulse generator for a 
data path in a semiconductor memory integrated circuit.
