Title: Conduction control circuit for thyristor
Inventor: KOBAYASHI TOSHIO
IPC: H02M1/08
Filed: 1981-11-02
Abstract: PURPOSE:To effectively control the conducting phase of a thyristor by employing an electric changeover switch as a control switch. CONSTITUTION:When an anode voltage reaches, for example, the offset voltage VOS of an N-gate thyristor 3 in case that the conduction of a thyristor is controlled, the thyrsitor 3 is conducted, and the gate signal C of a thyristor 1 obtained through a voltage dividing resistor 2 is given by the voltage dividing ratio of a charging resistor 51 to the resistor 2. The dividing voltage BD of the resistor 2 is set to a value less than the minimum value VGO of the gate signal  voltage of the thyristor 1 so that, even if the thyristor 3 is conducted, the thyristor 1 maintains non-conduction. The changeover switch 9 for the voltage dividing resistors 73, 74, 75 and an open terminal 76 can utilize a mechanical switch.

Abstract: PURPOSE:To prepare magnetic iron oxide particulate powder having a high coercive force, high saturation magnetization and good transfer characteristics, by modifying magnetic iron oxide particles with cobalt, ferrous salt and lead in a dispersion in a nonoxidizing atmosphere, filtering the modified particles, and drying the filtered particles. CONSTITUTION:An aqueous solution of a cobalt salt, an aqueous solution of a ferrous salt and a lead salt are added to a dispersion of magnetic iron oxide particles[FeOx.Fe2O3; 0<=(x)<=1], and an alkali is then added to the resultant mixture dispersion to give 0.05-3.0mol/l OH group concentration in the solution. The solution is then kept at 50-100 deg.C in a nonoxidizing atmosphere under stirring to give modified magnetic iron oxide particles containing 0.1-10wt%, expressed in terms of Co, 0.1-15wt% Fe expressed in terms of Fe<++>, Co, and 0.05-10wt% Pb expressed in terms of Pb. The resultant modified particles are then filtered and dried. Any particles of magnetite particles[(x) is 1], maghemite particles[(x) is 0]and particles of the intermediate composition may be usable as the raw material magnetic iron oxide particles.

Title: Printing cartridge
Inventor: NAGATOMO AKIRA
IPC: B41J2/175
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To eliminate the careless contact with a high temperature printing cartridge by an operator by causing a member which is expanded or deformed at a temperature higher than specified and is restored to its original size at a temperature lower than specified to be fitted into a removal preventing tool provided on a printer at the time of expansion or deformation. SOLUTION: If a printing cartridge exceeds a specified temperature level during continuous printing operation, a caulking member is expanded resulting in the deformation of the printing cartridge as shown by (b). The deformed caulk finds its way into a removal preventing tool 401 provided on the carriage of a printer main body. Consequently, the printing cartridge cannot be removed from the carriage of the printer until the temperature is lower than specified and the caulk is restored to its original size. Thus it is constituted that the printing cartridge cannot be removed from the carriage of the printer unless the temperature is returned to a level lower than specified. Therefore, an operator is protected against burn under whatever circumstances.  The material which is expanded at a specified temperature and is restored to its original shape at a specified temperature or less is bimetal.

IPC: G03G15/00
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To simplify a machining process for a paper feeding/discharging roller so as to facilitate its mass production by extruding a material, in which a specific amount of fluororesin with a specific grain size range or inorganic filler is added to thermoplastic elastomer, for the production and continuously cutting the molded material according to a required length. SOLUTION: A material, in which at least fluororesin with a grain size of 0.1-20.0 microns or inorganic filler is added to thermoplastic elastomer material, is extruded so as to be molded into a tube, and this tube is used for a paper feeding/discharging roller. In the case of usage as an upper roller in a paper discharge unit, dirt due to paper powder or toner can be prevented when a metallic roller, to which a ceramic coating processing is applied for the purpose of prevention of a paper deviation, is mounted as a lower roller. In this way, long-term stability can be secured and a cost can be greatly lowered.

Title: Controlling method for motor
Inventor: ANDOU TAKASHI
IPC: H02P27/08
Filed: 1980-12-10
Abstract: PURPOSE:To always operate a motor in the maximum efficiency state by driving the motor in accordance with a quasi-sinusoidal wave formed based on a power factor and a rotating speed. CONSTITUTION:When a pulse is applied from the terminal S1 of a controlling circuit 8 which receives signals from a rotating speed detector 11 and a power factor detector 10 to switching means 6, the switching means 6 will produce a DC power voltage +V having the same pulse interval and the same pulse width as the pulse from the terminal S1. When a pulse is then produced from a terminal S2, a DC power voltage -V having the same pulse interval and the same pulse width as the terminal S2 is produced from the output of switching means 7. The pulse outputs of these DC power voltages +V and -V are smoothed to a quasi-sinusoidal wave via a smoothing circuit formed of a coil L  and a capacitor C. In this manner, the frequency can be varied by varying the  pulse interval, and the effective voltage value can also be varied.

Title: Multilevel halftoning method
Inventor: HARRINGTON STEVEN J
IPC: H04N1/40
Filed: 1998-06-23
Abstract: PROBLEM TO BE SOLVED: To exactly constitute a pattern from two or more gray levels at once by determining a pixel intensity range, comparing it with a threshold value in two threshold value arrangements at least and selecting a pixel intensity level as the function of the compared result concerning a half tone cell according to the result. SOLUTION: The value of a pixel is compared with a pair of threshold values corresponding to the pixel by the longitudinal column of a comparator 2. The threshold values are allocated in ascending order, and when treatment is less than Threshold [0], [x] and [y], the comparison is erroneous and an inverter circuit makes L0 true. When it is higher than Threshold [N][x][y] and less than Threshold [N+1] [x] [y]. The comparison with the threshold value is true and the input of an inverter circuit 3 or inverted AND gate 4 is judged as an error concerning L0-Ln.
