Title: Magnetic color toner
Inventor: SUZUKI AKIRA
IPC: G03G9/08
Filed: 1983-10-19
Abstract: PURPOSE:To obtain a one-component type magnetic color toner capable of hiding the tone of magnetic particles and exhibiting rich sharp hues by forming core particles contg. the magnetic particles or coating them, coating the surface of said particles with a hiding layer contg. a white pigment, and further coating the surface of this layer with another coating layer contg. a coloring pigment. CONSTITUTION:A magnetic color toner is composed by forming core particles contg. or coating each magnetic particle, coating the surface of said particle with a hiding layer contg. a white pigment, and further coating the surface of said layer with a coating layer contg. a coloring pigment. The core particles contg. the magnetic particles are obtained by the ordinary granulation method, such as melt granulation or polymerization, and in the case of core coating, said granulation method can be applied to plastic transparent beads to form the coated core particles. The other layers can be formed, for instance, by spray coating or the like. The one-component type magnetic color toner of such a structure can hide the tone of the magnetic particles perfectly and sharply develop the color of a coloring pigment, thus permitting a color image rich in hue to be obtained.

Title: Symbol generation sweeping device for precision radar
Inventor: ASAKA KAZUMI
IPC: G01S7/22
Filed: 1985-09-03
Abstract: PURPOSE:To recognize the position of an aircraft exactly and easily by generating a symbol gate utilizing time other than time for sweep display and superposing a symbol that indicates the center of radar video on the radar video for each quadrant. CONSTITUTION:A symbol gate generator 21 generates a symbol gate at the time of switching of elevation sweeping and direction sweeping, and a symbol generator 23 receives the symbol gate and divides a symbol signal into X-axis component and Y-axis component and outputs to a summing circuit 24. A symbol position signal generator 22 calculates data of distance, azimuth, and angle of elevation of an objective aircraft detected by a radar transmitting and receiving device and divides symbol position signals that determine display position of the symbol into X-axis component and Y-axis component and outputs them to the circuit 24. On the other hand, logarithmic sweep waveform signals for Y-axis and X-axis sweeping are applied to the circuit 24 from a logarithmic sweep generators 15, 16. The circuit 24 composes input signals for X-axis and Y-axis systems and impresses to a deflecting coil 19, and superposes a symbol mark that indicates the center in the radar video on a CRT 20. Thus, the position of an aircraft can be recognized easily.

Abstract: PURPOSE:To ensure protection of the secrecy of the data stored in an EEPROM even in a test mode by providing a mode setting means which gives an access to the data of the EEPROM. CONSTITUTION:A decoder 12 delivers H in a normal mode and L in a test mode respectively. The output of the decoder 12 is supplied via a latch circuit 11 to a selection terminal of a selector 14 that selects the output of a parity generator which produces the even and odd parities for the data on a common bus. The selector 14 delivers an even parity and an odd parity to a latch circuit 15 when the input of the selection terminal is equal to H and L respectively. A parity checker 16 checks the parity of the data of the circuit 15 and delivers H with an even parity and L with an odd parity to a gate G1. In a normal mode the gate G1 is not opened since an L signal obtained by inverting the output of the circuit 11 by an inverter G2 is supplied to the G1. In a test mode the G1 is opened when the checker 16 detects an even parity data and secures an interruption signal to a CPU.

Abstract: PURPOSE:To obtain a compsn. as a water purifying agent having such characteristic that one-stage treatment of waste water contg. hexavalent chromium is enabled and enabling simultaneous treatment of org. pollutants by preparing an aq. iron salt soln. contg. ferrous ions and ferric ions in a specified ratio. CONSTITUTION:Hexavalent chromium in waste water is reduced to harmless trivalent chromium with ferrous ions, the pH of the waste water is adjusted to a nearly neutral range to convert the trivalent chromium into hydroxide together with ferric ions and org. pollutants are flocculated, settled and separated. At this time, the ratio between Fe<2+> and Fe<3+> in a compsn. as a water purifying agent is regulated to 1:>=2. COD and suspended solids(SS) as well as Cr<6+> are removed and iron ions are insolubilized, settled and removed. Since the waste water is treated in only one stage with only the purifying agent, the cost of treatment is reduced and equipment is simplified. Post-treatments such as separation of sediments and dehydration of sludge are advantageously carried out.
