Title: Process for hydrogenating solvents
Inventor: KURACHI KAZUHITO
IPC: C10G1/06
Filed: 1981-09-29
Abstract: PURPOSE:The aromatic carbon factor of the solvent is used to predict the reaction heat and the reaction rate by means of the material balance and heat balance in the hydrogenation column, thus controlling the operation of the reaction column to effect the hydrogenation of a solvent for coal liquefaction by representing the rate of hydrogenation of mixed solvent with a single parameter. CONSTITUTION:A solvent consisting of a much variety of aromatic hydrocarbons is hydrogenated in the hydrogenation column by using a hydrogenation catalyst in the presence of hydrogen under heating and then, the product is combined with crushed coal to form a slurry to effect the coal liquefaction in the reactor wherein the aromatic carbon factor (fa) of the solvent (fa is the aromatic ring carbon number of the solvent/the total carbon number of the solvent) is used to build up the material balance and heat balance in the hydrogenation column and calculate the reaction heat and reaction rate therewith. Thus, the operation of the reactor is controlled to effect the hydrogenation of the solvent as well as the coal liquefaction.

IPC: H04Q11/04
Filed: 1986-06-30
Abstract: PURPOSE:To surely detect end relieve a channel fault due to disturbance in clock for sampling data or talking noise by adding parity data to input data from a line so as to detect the parity dissidence being a prescribed value or over within a prescribed time of a reception data received via a time division switch. CONSTITUTION:Line circuits LC0, LC1 and trunk circuits TRK0, TRK1 convert an inputted analog signal into a PCM signal, adds a parity signal to the result of conversion and give the result to multiplexers MUX0, MUX1. After the output of the multiplexers MUX0, MUX1 is subjected to exchange by time division switches TDSW0, TDSW1, the result is received by the circuits LC0, LC1 and TRK0, TRK1 via demultiplexers DMUX0, DMUX1. The circuits LC0, LC1 and TRK0, TRK1 check the parity signal of the received data. When the parity dissidence of a prescribed value or over is detected within a prescribed time, channel parity fault information is outputted to a central processing unit CC. Thus, the central processing unit CC analyzes the fault information to change over a faulty channel or a time division switch from the active to the standby system.

The area 3 is equally divided for every predetermined pitch into (n) in the lateral direction of the press plate 2. In this case, a spacing into which the area 3 is equally divided is made the same as the screw width of the ink pot of a printing machine. Then, the area ratio of the area 3 is measured. Therefore, an image area ratio in the area 3 can be obtained by arithmetically processing the number of the whole picture elements in each of the area 3 by the number of bits bit on in the area 3. The result of a calculation is outputted by an output system, such as a paper tape or the like, according to a use.

Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To make possible sufficiently reducing cross talk even for a high recording density formed optical disk by optically correcting aberration based on a tilt error signal value. SOLUTION: Light receiving elements 34-36 in a light receiving device 27 receive any one reflection light among three reflection light from the disk 26. Sample-hold circuits 73-75 hold output the output level of the light receiving element 35 in response to a timing signal, and the hold output is sent to a comparison circuit 76 and an operation circuit 77. The comparison circuit 76 outputs a decision signal showing the circuit outputting an maximum value among the circuits 73-75.

Title: Reference position stopping system
Inventor: WATANABE AKIO
IPC: H02P8/00
Filed: 1989-06-15
Abstract: PURPOSE:To mainly avoid a danger of stepout of a stepping motor by correcting to stop the motor only in a normal rotating direction with a phase before a stopping phase to be mainly as a stopping target as a target. CONSTITUTION:A phase before a stopping phase of a stepping motor 3 corresponding to a reference stopping position to become a stopping target is used as a target after a reference position signal 4 is detected. In the final phase correction, if it is different from a target exciting phase, the motor 3 is normally rotated by one step. Then, an operation for checking the exciting phase is again repeated. A factor of reverse rotation of the motor 3 is excluded by this process. That is, a correction for the stopping phase is conducted only in the normal rotating direction to avoid a danger of stepout of the motor. Accordingly, a stop failure can be prevented. The stop failure can be also prevented even by varying the target stopping phase for a deviation of the signal 4 due to various conditions.

Title: Limiting amplifier
Inventor: MURAKAMI MITSURU
IPC: H03G11/00
Filed: 1982-09-02
Abstract: PURPOSE:To decrease the harmonic of even order number, by changing a DC bias voltage given to a limiting amplifier circuit in response to the amplitude of an input signal to bring an output of the limiting amplifier to 50% duty of DC level. CONSTITUTION:When the amplitude of an input signal is small, an amplitude detecting circuit 10 gives a detected output of a comparatively low voltage to a variable DC voltage source 11. Thus, the voltage source 11 gives a DC bias voltage comparatively low to an adder circuit 12 in response to the detected output. The circuit 12 superimposes a DC bias voltage on the input signal and gives the result to the limiting amplifier circuit 1. A DC bias voltage in response to the amplitude of the input signal is added to the DC bias voltage given in advance at the circuit 1. Then, the DC bias voltage according to the amplitude of the input signal is given to the circuit 1. Since the DC bias voltage is changed in response to the input signal, the operating point of the circuit 1 is changed in response to the DC bias, the duty of the outputted waveform at the DC level is brought to 50%, allowing to reduce the even order harmonic.
