Title: Magnetic toner
Inventor: NAKAMURA TAKASHI
IPC: G03G9/083
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To provide the magnetic toner superior in stability against environment, reproduction performance of a highly precise image and fixability by incorporating a binder resin and a black magnetite obtained by an ion electrolytic separation method. SOLUTION: The magnetic toner contains the binder resin and the black magnetite obtained by the ion electrolytic separation method. It is preferable that the magnetite has a specific surface area of 20-40 m<2> /g. Since the magnetite obtained by this method has a grain diameter of 20-60 μm, the distance between each grain when dispersed into the binder resin is widened to enhance its electric resistance. Since the corners of the magnetite grains are round, the grains are lowered in tendency to scratch the surface of the photoreceptor. The binder resin to be used is embodied by a polystyrene, a styrene-ethyl or n-butyl acrylate copolymer, a styrene methyl methacrylate copolymer, and the like, each alone or mixed with each other.

IPC: C01B21/068
Filed: 1981-06-22
Abstract: PURPOSE: To prepare α-Si 3 N 4  impalpable powder in high yield, by heating mixed powder consisting of SiO 2  and C in a specific weight ratio in an N 2  atmosphere containing a specified volume of CO in a specific temperature range.  
     CONSTITUTION: SiO 2  having a purity of ≥95wt% and particle diameters of ≤1μ is blended with C in a weight ratio of (1:0.4)W(1:8) to give mixed powder. This mixed powder is heated at ≥1,200°C and ≤1,550°C for ≥0.2hr in an N 2  atmosphere containing 0.01W20vol% CO. The existence of CO gas promotes the formation of SiO. But, when the volume exceeds 20vol%, the formed SiO is reacted with CO to form SiC and SiON 2 , to reduce the yield.

Filed: 1993-04-22
Abstract: PURPOSE:To classify digital and analog signal sources by applying voltages to arbitrary contacts through respective resistance among the contacts to which signal sources are connected and discriminating the potentials obtained at arbitrary contacts. CONSTITUTION:At contacts b and c to which a digital circuit board B is connected to a data transmitter A at the time of nonoperation, an FET element 23 and buffer circuits 24 and 25 becomes either all open drain or open collector. Thus, the potentials of the contacts b and c become Vcc through resistances 1 and 2 as pull up resistances. On the other hand, when an analog circuit base plate C is connected to the contacts b and c, the potentials at the contacts b and c are made to Vcc, 1/2 Vcc and 0 by making the values of resistances 31 and 32 of the plate C to infinity, R and O, respectively where R is the resistance value of the resistances 1 and 2. Thus, the signal sources is properly classified by switching changeover switches 3 and 4 to the side of comparators 6 to 9.

Abstract: PURPOSE:To obtain a printer apparatus capable of performing printing while moving a printing position, by performing printing corresponding to the movement of a printing head by the control of an operation processing part processed on the basis of magnetically detected positional information. CONSTITUTION:In this printer system, scanning for performing printing is manually moved to a lateral direction. Because of this, scanning occasionally shifts up and down and, in order to prevent this shift, a rule 4 is used. Further, a magnetized one of SNSN is added to a part of the rule 4. When a position detection part 2 passes by the single side of the rule 4, said detection part 2 passes several SNSN to generate voltage in a hole element 17 and this voltage is amplified by an amplifier 14 and positional information is transmitted to the side of a personal computer main body 21 and an operation processing part 13. The main body side sends printing information based on said positional information to the operation processing part 13 through an input latch circuit 22. The operation processing part 13 processes printing information so as to be capable of issueing output corresponding to the pulse of the positional information and sends the same to a thermal head part through a printing signal processing part 15 of perform transfer through a film 19.

Title: Character font data output system
Inventor: SAITO KENICHI
IPC: G09G5/24
Filed: 1990-04-13
Abstract: PURPOSE:To execute the development of a character font data on a graphic memory at a high speed by reversing and outputting the character font data from the character font memory. CONSTITUTION:Between the character font memory 1 stored the character font data and data buses 61 and 62 to transmit the character font data, a reversing means 3 which simultaneously reverses the character font data outputted from the character font memory 1 for every specified byte and outputs them to the data buses 61 and 62 is provided. Consequently, the character font data can be outputted to the data bus so that the character font data is normally developed on the graphic memory without executing the reversing processing by a CPU. Thus, when the character font data outputted from the character font memory is reversed, the CPU does not have to execute the reversing processing; therefore, the CPU reads out the character font data at the high speed and develops it on the graphic memory.

Title: Method of measuring amount of implanted ion
Inventor: ITOI KATSUJI
IPC: G01N27/00
Filed: 1987-04-20
Abstract: PURPOSE:To make it possible to measure the amount of implanted ions with high precision, by implanting ions having an opposite conductivity imparting type into a semiconductor substrate, applying a masking material serving against implanted ions on the substrate, again implanting ions at a high concentration to form a plurality of regions isolated from each other, and measuring the current flowing between the isolated regions. CONSTITUTION:Phosphorus ions are implanted in a P-type semiconductor substrate 1 at a low concentration to provide a phosphorus doped layer 2. Pressure-sensitive tape 3 is affixed at the center of the semiconductor substrate 1 such that it extends transversely from one end to the other of the substrate 1 and that it divides the substrate surface into two sections. Arsenic ions are implanted in the semiconductor substrate 1 at a high concentration to provide a highly doped layer 4. Then, the tape is removed and the semiconductor substrate is washed. By annealing it, a large depression-type transistor having two highly doped regions 5 is obtained from the semiconductor substrate 1. When a certain voltage is applied between the highly doped regions 5, an amount of current corresponding to the amount of phosphorus ions implanted into the semiconductor substrate 1 flows therebetween. In this manner, the amount of implanted ions can be measured with high precision.
