Abstract: PURPOSE:To easily obtain extracted coal almost free from residual ash and useful as a clean fuel free from air pollution, a raw material for high-purity carbon material, a chemical raw material etc., by treating a coal with a solvent of supercritical state and separating the extract from the residue. CONSTITUTION:A solvent (e.g. toluene) in a solvent tank 11 is pressurized to a specific pressure with a pump 12, introduced into a preheater 13, preheated at a prescribed temperature, introduced into an extractor 14, maintained in a supercritical state of high temperature and pressure and mixed with coal charged into the extractor 14 beforehand. The pressure of the mixture of the coal and the supercritical solvent is decreased to normal pressure with a flow control valve 15 and the depressurized mixture is introduced into a separator and separated into an extract and a residue, which are recovered with the separator 16 and a trap 17, respectively.

Title: Motor-driving circuit
Inventor: GOTOU MASAO
IPC: H02P6/10
Filed: 1980-07-08
Abstract: PURPOSE:To prevent the influence of the offset voltage and eliminate the fluctuation of the torque of a DC brushless motor, by inserting a resistor between the input terminal of a magnetic field detector and the input of an operation amplifier. CONSTITUTION:A current terminal 4a (5a) of a Hall element 4 (5) forming a magnetic field detector is connected to a current source 11 as well as to an operation amplifier 9 through a resistor R4. Setting the resistance value of the resistor R4 so as to be equal to that of a feedback resistor R2 permits the offset voltage generated in a stator coil 2 (3) to be zero. Accordingly, by connecting such a resistor R4, the influence of the offset voltage as well as the rotational torque fluctuation can be eliminated in a DC brushless motor.

Title: Frequency modulator
Inventor: MIMURO SATORU
IPC: H04L27/20
Filed: 1984-05-09
Abstract: PURPOSE:To obtain a frequency modulation signal small in jittering by inverting the output every time the time equivalent to a half cycle of a prescribed frequency after discriminating 1 and 0 of an input signal is counted and delivering a prescribed frequency signal. CONSTITUTION:A 1/0 discriminating means 2 discriminates ''1'' and ''0'' of an input digital signal. When a signal of 1200BPS, for example, is transmitted, a timer counting means 3 counts the time equivalent to a half cycle of 1,300Hz or 2,100Hz according to 1 and 0 of the means 2. An output means 4 inverts the output for each output of the means 3 to deliver alternately signals of 1,300Hz and 2,100Hz. An output inversion detecting means 5 detects the timing when the output of the means 4 is inverted. This detection signal and the discriminating signal sent from the means 2 are supplied to a phase calculating means 6. The means 6 calculates the degree of the phase of the output at a level changing time point of the digital signal and decides the residual degree where the output is inverted to feed the result of decision back to the means 3. Therefore, the jitter is reduced since the frequency component is obtained at the side which is immediately changed with the input change.

Title: Manufacture of semiconductor pellet
Inventor: INOUE KAZUHIRO
IPC: H01L21/301
Filed: 1985-04-30
Abstract: PURPOSE:To reduce adhesiveness securely in a short time by a method wherein a semiconductor wafer is stuck to a UV-cured type adhesive sheet and the wafer is divided into semiconductor elements and lights are applied to the back side and the front side of the sheet. CONSTITUTION:Scribed grooves 6 are formed by scribing the exposed surface 1a of a semiconductor wafer 1. The wafer 1 is divided into semiconductor pellets 7 by dicing. An adhesive sheet 5 is expanded to the radial direction to make spaces between the pellets 7. Lights 8a and 8b, which reduce the adhesiveness of the adhesive sheet 5, are applied to the back side of the sheet substrate 5a and to the exposed surfaces of the pellets 7. If the lights 8a and 8b are UV rays, curing of the adhesive layer 5b is progressed from the whole surface of the adhesive layer 5b on the substrate 5a side, from the exposed surface on the side of pellet 7 sticking and from the circumference parts of the back sides of the pellets 7. With this constitution, the adhesiveness can be reduced securely in a short time.

Title: Power converter
Inventor: YOKOYAMA TETSUYA
IPC: H02M7/48
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To attain early determination of a failed phase and power conversion, even when only one phase of a current detector system which detects three-phase AC current in a power converter has failed. SOLUTION: The rotational speed of a motor is fetched, and the primary current cycle of the motor is comprehended (step 51). Interrupt is generated for each cycle (step 55). An MPU reads the line current of the motor (steps 60-62). The current values of respective phases are integrated for each primary current cycle (steps 63-65). If the integrated value exceeds the reference value, it is decided that failure has occured (steps 66-67). A step 81 estimates the current value of the failed location, without a current detector at the failed position being used.

Title: Plating method
Inventor: IDO HIDEKAZU
IPC: C25D5/00
Filed: 1993-03-29
Abstract: PURPOSE:To execute an alloy plating having an excellent property in wear resistance and corrosion resistance by plating on a metallic substance while applying current between electrodes dipped into a solution containing metallic ion and heteropolyacid ion. CONSTITUTION:The plating is executed on the metallic substrate by dipping the electrodes into the solution containing one or more kind of the metal ion and one or more kind of heteropolyacid ion and applying current between the electrodes. The heteropolyacid ion is heterpolytungstic acid ion in the case of plating tungsten alloy and is heteromolybdic ion in the case of plating molybdenum alloy. As a result, since a pH regulator such as ammonia or a metal complexing agent is not used, the embrittlement or increase of internal stress of the plating layer is prevented and a high hardness plating is obtained without environmental contamination.

Filed: 1992-03-19
Abstract: PURPOSE:To enable a gear-cum-shaft, heightened with the extent of concentricity between gear and shaft, to be rolled with one machine capable of operation from turning to rolling of gear profile, and enable unmanned operation. CONSTITUTION:Some of two gear rolling tools 1 or more are symmetrically in a work spindle A of a numerically controlled lathe in a circumferential equi-dividing manner. A rotative driving part 2, imparting a relative rotation to the gear rolling tools 1 in the work spindle A for its rotation. In addition, a pressing drive part 4 is provided which shifts each of the gear rolling tools 1 as far as the specified value in the radial direction of a work 3. Also a control part 5 is provided which detects a turning angle of the work spindle A and imparts a specified relative rolling angle to the rotative drive part. With this constitution, since the gear rolling tools 1 roll the work 3 while pressing it from both sides in the radial direction, this work 3 will in no case deflect at all. A holding means for a free end of the work 3 becomes unnecessary and, what is more, any reprogramming attending on a change in length of the work is not needed, thus the promotion of unmanned operation is made achievable.
