Title: Potential sensor
Inventor: YAMADA HIROAKI
IPC: G01R5/28
Filed: 1982-05-21
Abstract: PURPOSE:To stabilize the performance by employing a ceramic substrate for the substrate carrying a sensor section and the like to make an amplification circuit hybrid. CONSTITUTION:A substrate 13 made of ceramics is provided thereon with a turning fork 2 to convert into alternate current the electric line of force 7 entering from a detection hole 1a of a case 1 and an electrode 3 to extract an AC signal from the electric line of force converted into alternate current. A piezo- electric ceramics 6 for driving is bonded on the turning fork 2. An output amplification circuit comprising a transistor 11 and a print resistance 12 is formed on the substrate 13 to be made hybrid and covered with a glass film. Thus, even in the case of a high humidity, a stable output voltage can be obtained without lowering the input impedance to stabilize the performance.

Title: Production of coal slurry in coal liquefaction process
Inventor: KAWABATA MUTSUMARO
IPC: C10G1/00
Filed: 1995-04-13
Abstract: PURPOSE: To obtain a high-concentration slurry by continuously adding coal and a catalyst to a solvent until the resulted slurry comes to have a target viscosity, while applying ultrasonic waves thereto and measuring the viscosity thereof, subsequently stopping the addition, restarting the addition when the viscosity reaches an inflection point, and repeating the above procedure. CONSTITUTION: A solvent 2 is introduced into a slurry preparation tank 4 and sent to a gas/liquid contacting apparatus 7, where the solvent is mixed with an inactive gas, e.g. N2 . The solvent is then fed to an ultrasonic wave applicator 8 with a circulating pump 12. After ultrasonic waves are applied to the solvent, it is circulated to the tank 4. Finely powdered coal 1 and a catalyst 3, e.g. iron sulfide, are then fed to the tank 4. The resulted mixture is circulated through the circulation line with stirring and application of ultrasonic waves. Thus, a slurry is prepared. During the circulation, the slurry viscosity is measured with viscometers 13 and 13' before and after the ultrasonic application. The addition of the coal 1 and the catalyst 3 is continued until the slurry viscosity reaches a target value. The addition is then stopped.  The addition is restarted at the time when the slurry viscosity has decreased to an inflection point, and is then continued until the slurry viscosity reaches a target value. Repeating the above procedure gives a high-concentration slurry having evenness of viscosity.

IPC: G01R35/00
Filed: 1986-04-16
Abstract: PURPOSE:To enable an output signal with a desired accuracy to be simply and easily taken out by using general purpose active elements by shifting the phase of a reference signal to make two or more subreference signals with different phases from one another. CONSTITUTION:A clock generator 1, using a quartz oscillator, generates a reference signal S0 having a repetitive frequency f0 with a required accuracy and inputs it to a delay unit 10 from an input terminal 3. The repetitive frequency f0 of the inputted reference signal S0 is integer times as much as the repetitive frequency (f) of an output signal S to be taken out and the frequencies f0 and (f) have a relationship represented by an expression f0=m.f (m=integer). The delay unit 10 sequentially delays the phase of the reference signal S0 by 1/n (n=integer) and divides the reference signal S0 to (n) subreference signals. The frequency divider 21 of a selector circuit 20 begins to divide the subreference signals that appear in the output terminals 1'-n' to 1/p [(p) is an integer] in synchronism with trigger signals G from a trigger generator 4 and an OR circuit 22 calculates the logical sum of the divided signals to output the signal S to a terminal 5.

Filed: 1986-04-16
Abstract: PURPOSE:To always a desired reference voltage to an input of a prescribed level and to reduce the steady-state current of the entire circuit by constituting a reference voltage correction circuit section and a comparator section by similar CMOSFETs. CONSTITUTION:A reference voltage is set to a value between TTL levels VIH and VIL, and an output VCOMP of a correction circuit section to a comparator section is decreased by  V when the conductance of N-MOSFETs M15, M13 is increased.

The correction circuit section and the series comparator section have the same circuit constitution, and when an IN voltage of TTL level is equal to a reference voltage VREF, the OUT voltage reaches VCOMP+ or - V. Thus, the variance of the manufacture process cancels the conductance of each FET of the comparator section by the VCOMP and the comparison voltage always constant is fed to the comparison section.
