Title: Magneto-resistance effect type magnetic head
Inventor: ABIKO SHUZO
IPC: G11B5/39
Filed: 1985-08-22
Abstract: PURPOSE:To permit the faithful reproduction of a signal waveform by using a high conductor material to constitute at least the part near the magnetic flux sensitive region of current terminal parts for passing electric current to a magneto-resistance effect element. CONSTITUTION:The regions 4, 4 existing near the magnetic field sensitive region of the current terminal parts 2', 2' connected to both ends of the magneto- resistance effect element (MR) element 2 are formed of high conductivity electrodes such as Al, Cu. Fe-Ni of the MR element 2 is made to remain as it is in the regions except the magnetic flux sensitive region in order to improve soldering. Since the terminal parts are partly formed of the high-conductivity material in the above-mentioned manner, the magnetic head does not longer receive the influence of the magnetic flux and can faithfully reproduce the signal waveform.

Title: Input buffer circuit of semiconductor memory element
Inventor: BAE HUY-CHEOL
IPC: G11C8/18
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To prevent a malfunction due to output noises, by neglecting for a predetermined time a change of an input signal if sensing noises, output noises are given rise to when a/CAS signal is converted from high to low. SOLUTION: When a row address strobe/RAS signal changes from high to low, an output of a node A and an output of a node B are maintained high. Therefore, an output of a second NAND gate NAND2 is determined by an output signal of a second inverter INV2 of a buffer input terminal 100. Subsequently, a/CAS signal is converted from high to low and a synchronous signal DOE is turned to high. Sensing noises and output noises are given rise to at this time after the/RAS signal falls. Since the DOE signal becomes possible an output of a NAND1 is maintained low for a delay time of an odd delay 210, thereby turning the NAND2 to high. A malfunction because of output noises is accordingly prevented.

Title: Carrier for developer
Inventor: KAWADA HIDEAKI
IPC: G03G9/113
Filed: 1989-07-14
Abstract: PURPOSE:To prevent spenting (formation of a toner film on the surface of the magnetic carriers) and to improve environment-resistance, flowability, electrostatic charge stability, and durability by forming a coated layer incorporating a specific silicone oil. CONSTITUTION:The coated layer incorporating the silicone oil expressed by formula I is formed. In the formula I, R1 denotes an alkyl group, phenyl group; R2 to R4 denote an alkyl group, phenyl group, org. group incorporating at least one primary alcoholic OH group; at least one point among R2 to R4 is the org. group contg. at least one primary alcoholic OH group; (n) and (m) denote positive integers. The hydroxyl group existing in the silicone oil, therefore, reacts with the hydroxyl group in the surface of a carrier core or in the applying resin and an immobilization reaction takes place. The immobilization of the silicone oil on the carrier surface is thus improved. Consequently, the spenting is prevented and the environment-resistance, flowability, electrostatic charge stability, and durability are improved.

Title: Formation of colored image
Inventor: YOKOTA TOSHIO
IPC: H04N9/07
Filed: 1980-12-24
Abstract: PURPOSE:To form a color image having a high-precision spectral transmission characteristics and a high-density colored image, by causing a cationic dye to be adsorbed to a transparent polymer layer having a given pattern formed by adsorbing a dye having at least an anionic group such as SO3 at its terminal group. CONSTITUTION:A polymer film, such as casein, gelatin, or PVA is formed on a substrate of glass or the like. and allowed to adsorb or impregnated with a dye having an anionic group, such as SO3<-> or COO<-> at its terminal group in a given pattern to form the first color pattern. Then, the polymer adsorbs or is impregnated with a cationic dye. When the polymer does not adsorb the cationic dye, the anion group of the adsorbed anionic dye adsorbs the cationic dye, so the first pattern is well dyed by the second dye. Accordingly, a colored image requiring high-precision spectral transmission characteristics or high density color is formed by >=2 color dyes, thus permitting a color separation filter for use in an image pickup tube or a solid-state image scanner, etc. to be obtained using organic dyes.
