Title: Method of composite conversion of 3c-4c paraffin in manufacture of tertiary alkyl ether and gasoline
Inventor: MOOSEN NADEIMI HARANDEI
IPC: C10L10/10
Filed: 1991-07-30
Abstract: PURPOSE: To obtain the subject compounds without forming methane by etherifying a feedstock containing a lower alkanol, an alkane, an alkene, etc., separating the tertiary alkyl ether and contacting the unreacted matter with a metallosilicate acid catalyst.  
     CONSTITUTION: A feedstock comprising lower aliphatic alkanols and C 3 +, C 4  or C 4 + aliphatic hydrocarbons containing alkanes and alkenes and rich in iso-olefins is fed from a conduit 10 into a reactor 20 and, together with an alcohol such as methanol introduced from a conduit 12, is etherified by contact with an etherification acid catalyst under etherification conditions. The product is transferred to a fractionating tower 40 and separated into an overhead stream 42 containing unreacted alkanols and C 4 + aliphatic hydrocarbons and an etherified effluent 41 containing a liquid product stream containing C 5 + alkyl tertiary alkyl ethers, and the overhead stream 42 is led to a reforming reactor 50 and subjected to high-severity contacting with a medium-pore metallosilicate acid catalyst at a temperature of 200-427°C under a pressure of 3,400 kPa or above to convert it into C 5 + gasoline boiling range hydrocarbons without forming methane.

Title: Frequency synthesizer using phase locked loop
Inventor: SEKINE SHINICHI
IPC: H03L7/22
Filed: 1987-07-29
Abstract: PURPOSE:To minimize the fluctuation of an output signal frequency and to complete phase locking in a short time, by supplying and outputting a signal to a phase comparator compulsorily immediately after starting the frequency division operation of a second frequency divider by an OR circuit. CONSTITUTION:The OR circuit 16 takes the OR of the output signal of a third control circuit 15 and that of the second frequency divider 12, and outputs a pulse with certain width immediately after starting the operation of the second frequency divider 12, then supplies it to the phase comparator 3, and performs phase comparison with a frequency division signal from a first frequency divider 11 by the comparator. Since a gate circuit 17 is set at a gate open state during the reset cancelling period of the second frequency divider 12, the output error signal of the phase comparator 3 passes the gate circuit 17, and is inputted to a charge pump 5, and is converted three values, (L), (H), or (Z) (high impedance), and is supplied to a low-pass filter 6. In such a way, it is possible to minimize the fluctuation of the output signal frequency at the time of starting respective operation of a phase locked loop (PLL), and to shorten a time to complete the phase locking.

Title: Signal processor
Inventor: MATSUMOTO MASAHARU
IPC: H03H17/06
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To realize a signal processor for performing FIR(finite impulse response) filter processing whose processing speed is fast. SOLUTION: A setting means 11 continuously sets newly inputted data S1, S2, and S3... at the tail of delayed data regions D1-D7 of a buffer 8. A data reading means 7 reads data set in the buffer 8, and applies the data to a multiplier group 1 having tap coefficients h1-h8. The multiplier group 1 multiplies the read data by each tap coefficient, and an adder 4 outputs the total sum of each multiplied result. When the FIR filter processing of one input data is ended, the data reading means 7 increases the data reading position by 1. Thus, it is possible to omit data shift for each data input in the buffer 8.

Filed: 1990-07-18
Abstract: PURPOSE:To enhance the efficiency dewing moisture in air and to improve the dehumidifying function by providing a guidance wall which is placed so as to surround an air leakage suppression gap S, guides the outside air led into a cooling area by a centrifugal action of a centrifugal fan to the outside peripheral part of the air leakage suppression gap, and maintains pressure in the vicinity of its air leakage suppression gap in a state that it is made higher than the open air pressure. CONSTITUTION:A part of the outside air led into an area R2 to be cooled by a centrifugal action of a centrifugal fan 16 is guided to the outside peripheral part of an air leakage suppression gap S by the inside surface of a guidance wall 24. The outside air guided to the outside peripheral part of the air leakage suppression gas S becomes higher than the outside air pressure by the centrifugal action of the centrifugal fan 16, and pressure resistance is generated in the outside peripheral part of the drying air leakage suppression gap S which leaks through the air leakage suppression gap S from the outside air whose pressure rises and the area to be cooled. Drying air which leaks through the air leakage suppression gap S from the area to be cooled decreases remarkably its speed by the pressure resistance. In such a way, the dehumidification efficiency can be improved.

Abstract: PURPOSE:To use plural lines by each time zone substantially with one set of telephone terminal set by providing plural identification codes and selecting an identification code by time for the use. CONSTITUTION:A switching time is set to a CPU 2 as a 1st switching time code and a 2nd switching time code, and when time information is coincident with the 1st switching time code, the CPU 2 gives a 1st control signal to a switch selection circuit 3. Thus, the circuit 3 selects the 1st identification code ID(a) and the code ID(a) is given to the CPU 2. On the other hand, when the time information is coincident with the 2nd switching time code, the CPU 2 gives a 2nd control signal to the circuit 3. Thus, the circuit 3 selects the 2nd identification code ID(b) and the code ID(b) is given to the CPU 2. That is, a telephone terminal set 4 makes talking with the code ID(b). Since the identification code varies with the time, one set of the set 4 uses 2 lines substantially.

Abstract: PURPOSE:To obtain a picture data with high sharpness by controlling the radiated luminous quantity to an original from a light source in response to a reflected luminous quantity from an original face so as to obtain an optimum picture contrast regardless of the color of original. CONSTITUTION:A read signal of a voltage level in response to the picture density outputted from a linear image sensor 57 is given to a binarization circuit 109 and an A/D converter 116.
