Title: Production of black phosphorus single crystal
Inventor: AKIMOTO SHUNICHI
IPC: C30B29/02
Filed: 1986-06-27
Abstract: PURPOSE:To obtain a black phosphorus single crystal having high quality, by carrying out the transition and melting of formed red phosphorus block to black phosphorus under high temperature and pressure and cooling the molten black phosphorus. CONSTITUTION:A formed red phosphorus block is subjected to transition and melting under high temperature and pressure and the obtained black phosphorus is cooled. The above formed block has extremely high uniformity and density (apparent specific gravity of 2.0-2.3) in contrast to a block produced by compression molding of powdery red phosphorus. The apparatus for generating high temperature and pressure used in the above process is especially preferably a slant-face driving cubic anvil-type high-temperature and pressure generator in view of operability and pressure reproducibility. It is important to use red phosphorus block in place of powder as the starting raw material in the present process. Red phosphorus can be produced by the transition of white phosphorus by heating and maintaining at >=200 deg.C. In the present process, the block produced from white phosphorus is trimmed or cut to a desired shape without crushing and is used as the starting material.

Title: Method of controlling elevator
Inventor: RARUFU EKUHORUMU
IPC: B66B1/20
Filed: 1988-06-17
Abstract: PURPOSE: To enhance the flexibility of transportation by dividing a plurality of elevators into two or more groups, determining their boundary on the basis of upward peak traffic conditions, and changing the boundary through the recalculation of an optimum zone boundary value on the basis of transportation capacity. CONSTITUTION: A sub-zoning computer 44 calculates an optimum zone boundary value by analyzing a traffic distribution in a building and, if the difference between a statistical value for a zone boundary and the calculated value does not exceed an allowable value, performs group control via group control devices 21, 22 by dividing a plurality of elevator car control devices 23-28 and in-cage control devices 29-34 into groups. When the allowable value is exceeded, an optimum zone boundary value based on short-term traffic statistics, the number of waiting people, and an available transportation capacity is recalculated, changed, and displayed on each display 37-42 via an elevator lobby control device 10. Upon completion of an upward peak or when the volume of upward traffic has fallen to or below a set value, sub-zoning is canceled.  Thus, flexible operation matching peak traffic can be effected.

Title: Method for protecting motor driving element
Inventor: SATO MITSUAKI
IPC: H02H7/085
Filed: 1991-06-24
Abstract: PURPOSE:To prevent a motor driving element from burning, by transferring a current signal through a primary filter, whose time constant is the same as the inner thermal time constant of the motor driving element, and by breaking a motor driving current when the output of the primary filter exceeds an allowable value corresponding to the allowable maximum temperature of the motor driving element. CONSTITUTION:A current sensor 1 is inserted in the driving line of a motor 2. The direction of the current sensed by the sensor 1 is determined by a direction discriminator 3. When the direction is plus, the output of the direction discriminator is inputted to a primary filter 4a, under the determination of the current flowing through a motor driving element Tr1. When the direction is minus, the output of the direction discriminator is inputted to a primary filter 4b, under the determination of the current flowing through a motor driving element Tr2. The outputs of the primary filters 4a, 4b are inputted to comparators 5a, 5b respectively. When the outputs exceed preset reference voltages E2a, E2b respectively, they act on a gate driving part 7 and make the gate of the motor driving element Tr1 or Tr2 off respectively. Thereby, the motor driving elements Tr1, Tr2 can be prevented respectively from burning due to overcurrents.

IPC: B41J2/355
Filed: 1981-09-25
Abstract: PURPOSE:To enable to make uniform the recording density even when recording is conducted at a high speed, by a method wherein dummy resistors for simulating temperature are used as a means for determining the current-passing period in the case where both the recording signal  in the preceding input and that in the present input are asigned to black images. CONSTITUTION:The recording signal information supplied to a driving circuit 27 for selectively passing an electric current to a plurasity of heating resistors 14a... in the present input and that spplied in the preceding operation are stored respectively in the first and second memory circuits 24, 25 and they are compared to each other for each corresponding bit. The current- passing period in the case where both the image in the preceding input and the image in the present input are black is set to be shorter by a predetermined period of time than the current- passing period in the case where the image in the preceding input is white and the image in the present input is black, by a controlling circuit 26 for the current-passing period and a determining circuit for the current-passing period. The determining circuit detects the temperature  by sequentially passing an electric current to a plurality of the dummy resistors 15a-15d located adjacently to the heating resistors 14 while utilizing the temperature coefficients of resistance of the resistors 15a-15d, and a signal for stopping the passing of the current is generated through a comparator group 21 when the temperature detected reaches a predetermined level. Accordingly, the temperatures of the heating resistors 14 can be simulated accurately, and uniform printing density can be obtained even when printing at a high speed.

Title: Combustion device
Inventor: NAKAMURA HARUTOKI
IPC: F23D3/18
Filed: 1977-12-14
Abstract: PURPOSE: To eliminate noxious and foul-smelling components such as CO, HC and NOx contained in exhaust, by using sheet catalyst in a combustion chamber.  
     CONSTITUTION: A catalyst 12 made of silica cloth containing platinum is fixed by means of fittings 13, 14 to the inner surface of a combustion cylinder 4 fitted  through a sealant 5 to the upper surface of a fuel tank 1 of a kerosene burner. When kerosene is carbureted and burnt at the upper end of a wick 3 around a cylinder 2 at the center of the fuel tank 1, the catalyst 12 accelerates the oxidization of unburnt components. Since the catalyst 12 keeps its temperature level required for a while even after the flame is extinguished, the said oxidization can continue, which can remove noxious components in the exhaust as well as eliminate generation of smell at the time of ignition and extinguishment.

Abstract: PURPOSE:To largely improve efficiency, by welding heat rediating wings, some of which have a partial cut-out part, on the periphery of a collector core, and housing a magnet for deflection in the cut-out parts of the heat rediating wings. CONSTITUTION:A collector part 5 consists of a plural number of heat radiating wings 7 made of copper which are brazed on the periphery of a collector core 6 made of also copper. Cut-out parts are formed partially in some of these heat-radiating wings 7, and therein a magnet 8 for deflection is housed so that its magnetic pole is orientated to the center of the collector core 6. Thus, a magnetic field of sufficient strength, vertical to the tube axis can be generated inside the collector 6.

Abstract: PURPOSE:To calculate error and defect rates according to actual defects by monitoring a defect due to a certain defect and several bits preceding and following an error signal and connecting them as one defect or error at the time of detecting another defect or error signal within a certain threshold. CONSTITUTION:The reflection signal from an optical disk 1 is converted to an electric signal by a detector 8 and is amplified by a summing amplifier 10 to obtain an RD signal 30, and this signal is outputted to a comparator 26 through differentiating, binarizing, and data extracting circuits 23, 24, and 25. The comparator 26 compares the WR signal of a WR pattern generator 22 with the RD signal and outputs an extracted error (E) signal 31 to an E position detecting circuit 28. A CPU 29 weights and connects four bits of R from the E position signal of the circuit 28; and if E appears in 66 to 67 bits and successively appears in 68 to 69 bits, they are processed as one defect E. Thus, the E rate and the defect rate according with actual defects on the disk 1 are calculated.
