Title: Preparation of ferromagnetic iron oxide containing cobalt
Inventor: NAKADA KAZUO
IPC: C01G49/00
Filed: 1981-12-26
Abstract: PURPOSE:To prepare magnetic iron oxide, containing cobalt, and having improved coercive force as a magnetic recording medium, by applying a metallic compound containing the cobalt to the surface of a magnetic iron oxide powder, filtering the resultant  slurry, washing the filtered cake with water, dispersing the washed cake in water, and heating the resultant slurry under pressure. CONSTITUTION:A magnetic iron oxide powder, e.g. gamma-Fe2O3 or Fe3O4, is dispersed in  water to form a slurry, which is then mixed with an aqueous solution containing a Co  salt, e.g. cobalt chloride, cobalt sulfate or cobalt acetate, dissolved therein and agitated.  An aqueous solution of an alkali, e.g. NaOH, is then added to the slurry and agitated  to apply the Co salt to the surface of the iron oxide particles. The resultant slurry is  then filtered, and the cake is washed with water and introduced into an autoclave. The  air in the autoclave is expelled and replaced with a nonoxidizing atmosphere, e.g.  nitrogen, and the resultant cake is then dispersed in water in the autoclave to give a  slurry, which is then heated at the boiling point or above under pressure, e.g. 105-200 deg.C  while pressurized at 1.1-20 atm. The slurry is then filtered, and the resultant cake is washed with water and dried in the air to give the aimed magnetic iron oxide, coated  with 1-10%, based on the magnetic iron oxide, Co, and having a great coercive force.

IPC: H05B33/12
Filed: 1990-08-13
Abstract: PURPOSE:To emit a strong and focused light by re-emitting the light emitted from the end surface of a thin film electroluminescence layer in a different direction from that of emission. CONSTITUTION:When a high voltage is applied between each metal electrode 2 and 6, electroluminescence emission is generated in an emission layer due to a strong electric field.

The light emitted from the end surface is reflected by the surface of a projection 7, and the light is emitted perpendicular to a substrate. Namely, the light generated in the emission layer 4 is reflected by the projection 7, and the light can be effectively extracted vertically and upward to the substrate. Although the projection 7 is provided at an angle of 45 deg. to the substrate in such a way that the emitted light is reflected in the vertical direction, the angle may not be 45 according to purposes.

Title: Apparatus for removing impurity of gas charged electric apparatus
Inventor: YOSHIOKA TAKEO
IPC: H01F27/20
Filed: 1981-12-24
Abstract: PURPOSE:To remove SF6 decomposed gas generated when an SF6 gas apparatus is broken, by a method wherein a treating tank is divided into plural regions by a hydrophilic fiber filter and opening and closing valves of each regions are controlled corresponding to the pressure variation of a gas to be treated. CONSTITUTION:An SF6 gas apparatus is connected to an impurity removing apparatus 4 wherein a treating tank 41 accommodating a reactive absorbing liquid 451 such as a Ca(OH)2 solution is divided by plural reaction filters 44 made of a hydrophilic fiber and SF6 gas containing SF6 decomposed gas such as SF4 or HF is flowed into said apparatus 4 from a flowline 21 to open an opening and closing valve 421. The SF6 gas is passed through all reaction filters 44 and the SF6 free from the decomposed gas is flowed out from an outflow port 431. Because a treating amount per a unit time is reduced as the pressure of the inflow gas is lowered, a pressure detecting apparatus 8 detects that the pressure of the inflow gas reaches a predetermined value or less and an opening and closing valve 422 is opened while the opening and closing valve 421 is closed to restore the treating amount per a unit time. Hereinafter, valves 423, 424 and valves to be opened are shifted siminlarily and successively.

Title: Optical system driving system of copying machine or the like
Inventor: TANIMOTO YASUFUMI
IPC: G03G15/04
Filed: 1982-12-03
Abstract: PURPOSE:To shorten a copying time, and to eliminate the disorder of stop position of an optical system by changing a moving speed of the optical system by an operation. CONSTITUTION:An optical system for scanning optically an original by executing a reciprocating motion relatively against the original is driven by a pulse motor 31. A driving circuit 45 drives to rotate a motor forward or backward in accordance with a rotating direction designating signal from a microprocessor 41. Also, at the time of a forward rotation (when the optical system moves in the original scanning direction), the optical system is driven by a one-two phase energizing system, and at the time of a backward rotation (when it is returned to the scanning start position), it is driven by a two phase energizing system, and at the time of stop, it is stopped by one phase energizing by switching forcibly the two phase energizing to the one-two phase energizing. As a result, a copying is shortened by shortening a reciprocating time of the optical system, and also the disorder of stop position of the optical system can be eliminated.

Title: Key storage control system
Inventor: NAKAYAMA SHINJI
IPC: G06F12/10
Filed: 1985-09-27
Abstract: PURPOSE:To prevent influences of errors upon a system by writing '1' in reference and change bits if an error is found when the writing of reference and change bits is requested and paging out a corresponding page on a main storage to an external storage device as a data changed page. CONSTITUTION:In case of access from a CPU 1 to a main storage MS, control signals are divided into a control signal to the main storage MS and that to a KS 3 by a main storage control part 2. In the KS 3, data expressing request contents is checked by a check logic 31 and is inputted to a modifying logic 33 together with the check result. The input is selected in the logic 33 as it is unless an error signal is inputted from the logic 31; but if the error signal is inputted, the updating request of both of reference and change bits is selected and is set to a write register 36. When R of the register 36 is set, '1' is written on only the reference bit of a key storage 37; and when RC of the register 36 is set, '1' is written on both of reference and change bits of the storage 37. Thus, corresponding main pages are subjected to reference and writing.

Abstract: PROBLEM TO BE SOLVED: To simplify the construction of the whole of a device and to enable easy installation of the device on a vehicle or others by using a tactile sensor which detects an object electrically by the contact of an antenna with an electrode part. SOLUTION: A tactile sensor 3 detecting an object electrically by the contact of an antenna 1 with a surrounding electrode part 2 which is caused by the movement of the antenna 1 at the time when it comes into contact with the object and is warped thereby, is used. Being supplied with a power of a battery 4 when the antenna 1 comes into contact with the electrode part 2, a buzzer 5 comes to a state of operation and gives information that the object is detected. The electrode part 2 is formed in the shape of a ring so that the antenna 1 can touch the electrode part 2 in any direction of its warp due to the contact with the object, and the antenna 1 having elasticity and a linear shape is disposed at the center of the ring.  By setting the dimension of the diameter of the ring-shaped electrode part 2 properly, the sensitivity of detection of the object is determined by the amount of the warp of the antenna 1 at the time when it touches the object and comes into contact with the electrode part 2.

A wafer 6 which has been etched in the first etching chamber 1 is transferred to a cleaning and drying device 2 by using a transfer device 4; the wafer is cleaned; the foreign substance 14 is removed. After that, the cleaned wafer 6 is transferred to a second etching chamber 3 by using a transfer device 5; if the wafer is etched again by using an identical mask 13, the wiring material 12 at a part X which was not etched last time is etched. By this setup, a normal wiring pattern where both X and Y have been etched and which does not contain any defect is formed.
