Title: Gate control method for thyristor convertor
Inventor: TAKAHASHI TADASHI
IPC: H02M1/08
Filed: 1977-09-19
Abstract: PURPOSE: To minimize the required gate power, by controlling the gate of thyristor, based on the AND output of the forward voltage signal detected more than a given value.  
     CONSTITUTION: In normal operation, although the arm forward voltage is applied from t=t1, no forward voltage signal FVS is developed until t=t2. Since the arm forward voltage reaches the forward voltage detection level VFVL at t=t2, the forward voltage signal FVS is taken place. However, since the gate control reference PHS is zero from t=t2 to t=t3, no gate pulse is taken place and the gate pulse GP τ in the pulse width is taken place at the same time when the reference PHS is taken place at t=t3. Since the arm current is discontinuous during the conduction period at the cycle started from t=t4, twice gate pulse GP is taken place during conduction region. It is suitable for the pulse width τ of the gate pulse GP for several μ sec to several tens of μ sec, relating to the turn on time of thyristors. Accordingly, the disadvantage of conventional defects can be eliminated and the system is simple and the tage pulse width can be decreased extremely

Title: Double convergence mass spectrometer
Inventor: TAKEDA TAKEHIRO
IPC: G01N27/62
Filed: 1984-05-31
Abstract: PURPOSE:To achieve a high resolution by producing in a double convergence mass spectrometer a deflection magnetic field (phim=60 deg.) and a troidal electric field in which the radius of the ion orbit is specified relative to the radius of the ion orbit in the magnetic field and installing a tetrode lens for aberration correction on the ion orbit. CONSTITUTION:A double convergence mass spectrometer is constituted of a deflection-type electromagnet (M) for producing a deflection magnetic field (phim=60 deg.) and a troidal electrode (TE). When the radius of the ion orbit in the magnetic field is supposed to be (am), the radius (ae) of the ion orbit in the troidal electric field is restricted to the range determined by the formula 0.625am <=ae<=0.675am. Additionally, a tetrode lens (QL) for aberration correction is installed on the ion orbit. Therefore, it is possible to analyze a compound with a high molecular weight by increasing the radius (am) of the ion orbit in the magnetic field without increasing the size of the electromagnet (M). Furthermore, it is possible to achieve a high resolution by reducing the aberration of the whole ionic optical system including the magnetic field and the electric field.

Title: Overheat preventive device of electromagnetic clutch for vehicle
Inventor: MAKITA FUJIO
IPC: F16H63/20
Filed: 1980-08-15
Abstract: PURPOSE:To decrease the slip of a clutch and prevent its temperature rise, by increasing a control current in proportion to the temperature rise of the clutch. CONSTITUTION:A voltage detector circuit 51 and current detector circuit 52 detect the voltage and current of a clutch coil 44, then an arithmetic circuit 53 calculates a resistance value of the coil 44 from these signals. A resistance value signal is converted to a temperature change by a corrector circuit 54 and transmitted to a proportional pluse generator circuit 45 to adjust a clutch current by the method of pulse width control. Since temperature is measured by the coil voltage and current then the coil current is controlled, a time for half clutch operation can be decreased in accordance with the temperature rise, further the temperature can be prevented from increasing.

IPC: G01R33/48
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To prevent degrading of the quality of a tomographic picture by reducing effect as caused by changes in the surrounding environment of a magnetic field of a magnetic field generation means. SOLUTION: A magnetic field sensor 21 is arranged near an electrostatic magnetic field generation magnet 2 to measure the environment F of a magnetic field. Any change in the environment F of the magnetic field is detected by a magnetic field sensor 21 and a detection signal is inputted into a sequencer 7 through an A/D converter 22. The sequencer 7 translates the change in the magnetic field into a frequency and outputs a frequency signal after the changes in the magnetic field to a transmitting system 4 and a receiving system 5. This eliminates the need for a correction magnetic field coil and a correction control circuit to cancel changes in the surrounding environment of the magnetic field thereby significantly improving installing availability and cost.

IPC: H01J9/44
Filed: 1980-08-19
Abstract: PURPOSE:To prevent damage of a cathode by performing preset raster aging after the first filament aging process and emission, the first gas, the second gas, and the second filament aging. CONSTITUTION:After the first filament aging process by preheating, 0V, 50- 100V, 300-400V, and 400-500V are applid to the first, second, third, and fourth grids, respectively and raster aging is performed for 15-20min by means of approximately 0.5-1mA cathode current. Subsequently, emission, the first gas, the second gas, and the sencond filament aging is performed. Thus, the raster aging process ionizes CH4, easily absorbs it in Ba of a getter, and improves the degree of intra- tube vacuum. As a result, even when the ionized gas after cathode aging collides with the surface of the cathode, the cathode is prevented from being damaged.

Abstract: PURPOSE:To generate proper reference data by inputting data of a data string generated by on/off operation of a signal group operated periodically by teaching data so as to recognize an useless signal on the generation of reference data properly and quickly. CONSTITUTION:A sensor controller 100 inputs a signal including signal performing a periodic on/off operation by sensors S1-Sn and an input circuit 101 to generate reference data. A CPU 102 discriminates whether or not the signal group includes an useless signal for generating the reference data. When the CPU 102 discriminates presence of the useless signal, the CPU 102 recognizes that the signal group is an improper signal group for generating the reference data. The CPU 102 extracts plural characteristic quantities of the teaching data received by teaching and uses at least two of the quantities to make discrimination according to a prescribed discrimination rule. Thus, the reference data is generated properly.

Abstract: PURPOSE:To prevent toner blocking by carrying toner falling from an agitating member in the 2nd part of the bottom of a hopper toward a toner discharge roller when the agitating member returns to a 1st part. CONSTITUTION:The toner discharge roller 46 is housed in a recessed part 65 dividing the bottom of a toner hopper 41, and provided with the agitating member 52 which crosses the recessed part 65 from the 1st part of the bottom of the hopper toward its 2nd part, moves along the entire bottom of the hopper and returns to the 1st part. The agitating member 52 is arranged such that when it returns, it comes close to the 2nd part of the bottom. Therefore, the toner dropping to the 2nd part is scraped away to the recessed part 65 by the agitating member 52 to prevent blocking. As a result, almost all of the toner in the toner hopper can be used and is not used wastefully. Since the capacity of the toner hopper can be made best used, a toner replenishing interval can be extended.
