Title: Picture processor of synthetic aperture radar
Inventor: MURATA MINORU
IPC: G01S13/90
Filed: 1981-07-20
Abstract: PURPOSE:To easily attain compensation of distortion and reduction of a noise, by using both a data obtained by Fourier conversion of a conjugate function of a transmitting signal at the time of range compression, and a data obtained by Fourier conversion of a time domain reference function at the time of azimuth compression. CONSTITUTION:In a range compression part A, a data obtained by high speed Fourier conversion in an FET circuit 9, as to a conjugate function of a transmitting signal obtained by a time domain reference function generating circuit 8 is multiplied by a data obtained by high speed Fourier conversion in the range direction in an FET circuit 10, as to a synthetic aperture radar (SAR) data, by a multiplier 11. The data obtained in this way is subjected to Fourier reverse conversion in an IFFT circuit 12, and after that, is arranged in the azimuth direction by a corner turning circuit 13. In an azimuth compression part B, the processing is executed by a time domain reference function generating circuit 15, FET circuits 14, 16, a multiplying circuit 17 and an IFFT circuit 18 in the same way.

Title: Cream solder
Inventor: MURAKAMI SHIYUUICHI
IPC: B23K35/22
Filed: 1984-06-01
Abstract: PURPOSE:To hold uniformly solder particles and flux components without sepn. by consisting cream solder of a flux contg. a resin which dissolves in the solvent of the flux at an ordinary temp. and a resin having limitation in the solubility and solder powder. CONSTITUTION:The structure in which a resin 4 having the solubility limit in the solvent at an ordinary temp. exists spottedly in the resin 2 dissolving thoroughly in the solvent at an ordinary temp. and in which the surface of the resin 4 is softened by the effect of the solvent and has weak tack is formed. As a result, the solder particles dispersed uniformly in the flux do not settle and the sepn. of the solder particles and the flux is obviated. The resin having the solubility limit with the solvent at an ordinary temp. dissolves thoroughly at the melting temp. of the solder and therefore the flux 5 mixed uniformly with the resin and activator covers the periphery of the solder particles 1. Soldering is thus executed as in the conventonal manner.

Title: Electrophotographic toner and picture forming method
Inventor: SHIRASE AKIZO
IPC: G03G15/08
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To obtain a toner with the variations of chargeability with the environment reduced, uniform in chargeability, having a sufficiently high picture density and reproducibility of characters and thin lines, low contamination property, rich durability and with the fluctuations of characteristic decreased by forming an inorg, additive by treating a specified silica with a titanate coupling agent. SOLUTION: This toner consists of a resin, colorant and inorg. additive, and the inorg, additive is prepared by treating a silica having <=100m<2> /g BET specific surface and contg. <=0.2% Al2 O3 with a titanate coupling agent. When the BET specific surface is >100m<2> /g, an excess current is easily applied, the diameter of the fine grain is decreased, hence the fine grain is embedded in the toner surface when in continuous use, and the toner performance, especially the transfer performance, is made insufficient. Besides, when the Al2 O3 content exceeds 0.2%, the treatment with the titanate coupling agent is made nonuniform, and the chargeability of the toner and its environment are adversely affected.

Title: Power controller
Inventor: SHIOMI TSUTOMU
IPC: H05B41/24
Filed: 1985-05-27
Abstract: PURPOSE:To reduce the adverse influence given to the output of a detection part due to the vibrations produced by the ON/OFF actions of a switching element, by providing a vibration component eliminating means to the detection part. CONSTITUTION:A detection part A10 contains a vibration component eliminating means A100 which eliminates the adverse influence given to the detection output due to the oscillating voltage or current produced by the ON/OFF actions of a triac Q1 serving as a switching element. Thus the means A100 eliminates effectively the vibration component of the voltage supplied to a rectifying/ smoothing circuit consisting of a diode bridge DB1 and a capacitor C2. Thus the vibration component ratio is decreased extremely for the voltage VC2, i.e., the detection output of the part A10. This secures the characteristics of the part A10 with satisfactory linearity and therefore reduces the adverse effect given to the output of the part A10 due to the vibrations produced by the ON/ OFF actions of the switching element.

Filed: 1988-05-09
Abstract: PURPOSE:To attain display which does not give a sense of incompatibility to a user by permitting a control means to store all the character codes or character data of the name of broadcasting stations by corresponding to address codes and transmitting character data to a display means. CONSTITUTION:The address codes and the character codes are detected from one group of RDS (radio data system) data which multiplex digital data to an FM radio signal, and the character codes are stored in the area of a code memory 19 corresponding to the address codes. The character codes by eight characters are stored in the code memory 19 and the character codes are read in the order of the addresses. Then, character data corresponding to the character codes are read from a font memory 20 and stored in a data memory 18. Character data in the data memory 18 are transmitted to a driving circuit 9 and simultaneously displayed in a character display after seven seconds elapse in such a state, for example. Thus, the names of the broadcasting stations are simultaneously displayed when additional data are multiplexed, and the sense of incompatibility is not given to the user.

Title: Coating method
Inventor: TANTANI MIKIO
IPC: B05D3/00
Filed: 1991-04-16
Abstract: PURPOSE:To enable coating by one coating process regardless of a cross-sectional shape by coating the decorative surface of a base material with a necessary amount or more of paint and subsequently transferring the coated base material to space held to a vacuum state and sucking air at a high speed when the coated base material is passed through an insertion port to suck and remove the excessive paint. CONSTITUTION:A necessary amount or more of paint is applied only to the decorative surface of a base material. Subsequently, the coated base material is passed through an insertion port slightly larger than the base material in a vacuum state to be transferred to vacuum space. Since this space is in a vacuum state, air is always sucked from the insertion port and the base material closes the insertion port so as to leave a slight gap when it is passed through the insertion port and air is sucked from the insertion port at a high speed. Therefore, the excessive paint not bonded to the base material is sucked and removed when the high speed air comes into contact with the base material. The removed paint is separated from air and again circulated to a coating machine to be applied to the base material.

Abstract: PURPOSE: To form a slot-type fluorescent screen which is narrower than the shadow mask slot by growing a sharp-slope profile for the luminous intensity distribution through exposure with a decreased effecitve light source diameter of the mercury lamp and with the varied refractive index of thecooling medium.  
     CONSTITUTION: For the exposure of the fluorescent screen of the color picture tube which uses the long-arc type mercury lamp for a direct light source, the light source is positioned at the place displaced more than three positions at least in the orthogonal direction to the axial direction of the fluorescent stripe. In this case, the effective light source diameter is varied for the desplaced position by changing the refractive index of the cooling medium of the mercury lamp. In order to avoid the exposure caused by real shadow part 6a, one of the three exposure positions is positioned to oppose to the slot center. And the exposure position is cooled down by thebarium iodide saturation solution of 1.63 refractive index to secure the light source diameter of 0.92 for exposure
