Title: Magnetic recording medium
Inventor: TAKIZAWA TOSHIMITSU
IPC: C10N40/18
Filed: 1984-01-31
Abstract: PURPOSE:To improve the durability of a magnetic recording medium by forming lubricating layers which are different from each other in material or thickness on the 1st and the 2nd sides of the medium so as to realize the most suitable lubricating conditions. CONSTITUTION:Magnetic layers 3 are formed on both sides of the nonmagnetic substrate 2 of a magnetic recording medium 1 for one-side recording. A lubricating layer 4 of 200-300Angstrom  thickness is formed on the magnetic layer 3 not concerned with the recording and reproduction of data by spin-coating oleic acid. The layer 4 contacts with a head load pad 6. A lubricating layer 5 of 50-100Angstrom thickness is formed on the magnetic layer 3 concerned with the recording and reproduction of data by spin-coating oleic acid. The layer 5 contacts with a magnetic head 7. Since the layer 4 contacting with the pad 6 is thick, satisfactory durability is provided, and since the layer 5 contacting with the head 7 is thin, superior recording and reproducing characteristics are provided.

Filed: 1990-01-23
Abstract: PURPOSE:To facilitate the connection with an active component such as a transistor(TR) or a diode and to reduce the effect of a stray impedance of a capacitor by connecting a ground terminal of an input stage and an output stage of plural strip lines to the ground via the capacitor. CONSTITUTION:Strip line conductors 15-19 are selected to be a length equivalent to 1/4 wavelength of the center frequency of a transmission signal band and one terminal is connected to a ground conductor formed on the rear side of a dielectric board through throughholes 21-23 penetrating through the dielectric board plated with a conductor. One terminal of strip line conductors 15, 19 connected to the leadout electrodes 10, 11 for an external circuit are connected to a ground conductor via capacitors 12, 13 for DC blocking respectively. Thus, a DC block capacitor inserted between an interdigital filter and an input or output of an active element is not required and the increase in the transmission loss due to the capacitor is avoided.

Filed: 1986-01-25
Abstract: PURPOSE:To widen the allowable range of intervals for setting a structure by fitting the fitting portion of a seal rubber of a cross sectional form in which the tip of the fitting portion is of expanded width into a groove. CONSTITUTION:Grooves 4, 4 for fitting seal rubber are provided in parallel on sides 3, 3 facing the joint 2 of a caisson 1.

IPC: G03B35/00
Filed: 1984-01-30
Abstract: PURPOSE:To obtain a stereo television which has satisfactory light transmittivity and allows bright picture recognition by providing a pair of transparent plates arranged in parallel, a pair of transparent electrodes arranged in the inside of these plates so that they will face each other and dynamic diffusion liquid crystal sealed between these electrodes for right and left light shutters. CONSTITUTION:Transparent electrodes 20a and 20b are fixed at facing surfaces of two transparent plates 19a and 19b arranged in parallel, and between both transparent electrodes 20a and 20b a dynamic diffusion liquid crystal 21 is sealed. When a voltage is impressed between both transparent electrodes 20a and 20b, in a light shutter 18a the molecular array of the liquid crystal is diffused due to the torque of ions running in said crystal 21, and light diffusion occurs; therefore the light transmittance is decreased and the liquid crystal becomes opaque. On the other hand, when a voltage becomes zero, the molecular array becomes arranged, the light transmittance is higher, and the liquid crystal becomes transparent. By means of a shutter drive means 16, specific voltages V1 and VR are alternately impressed to the light shutter 18a at the left side and the light shutter 18b at the right side by synchronizing left and right image signals, respectively, by the specific period.

Title: Manufacture of nickel hydroxide electrode for alkaline storage battery
Inventor: OZAKI KAZUAKI
IPC: H01M4/32
Filed: 1992-01-30
Abstract: PURPOSE:To improve the filling efficiency of the active material by holding alkali in a porous nickel sintered board, and thinning down the alkali concentration of the surface of the board than that of the core side, and impregnating the board with the acidic nickel salt aqueous solution. CONSTITUTION:After impregnating a board with the acidic nickel salt and performing the alkali processing to it, a part of the alkali is eliminated by the washing, and the board, of which part holds alkali, is dipped in the water for some ten seconds. The moisture thereby penetrates into the board to dilute the alkali of the surface and increase the alkali concentration near the board core body higher than that of the surface of the board. At the time of impregnating this board with the acidic nickel continuously, the conversion to nickel hydroxide is generated in the water primarily near the board core body to prevent the blinding on the surface of the board. The conversion to nickel hydroxide is generated simultaneously with the impregnation with the acidic nickel salt and the alkali processing and the next impregnation with the acidic nickel salt. Consequently, a highly concentrated nickel nitride aqueous solution or the like is not used as the impregnation liquid to perform the filling efficiently.

IPC: F28F1/32
Filed: 1986-01-27
Abstract: PURPOSE:To improve heat transfer rate by a method wherein both front and rear surfaces of a plate fin is provided with a multitude of louver type raised- slotted parts at an interval between heat transfer tubes and the sides thereof are slanted with respect to airflow. CONSTITUTION:Boundary layer leading edge effect, precluding the development of temperature boundary layer, is contrived by louver type raised-slotted parts 11a-11f. Further, the sides 11g'-11e' of the raised-slotted parts are formed so as to be slanted with respect to the inflow direction of the airflow B, therefore, the airflow B collides against said sides and generates eddies whereby the improvement of heat transfer performance due to the promotion of turbulent flow may be contrived. On the other hand, the airflow B flows along the raised- slotted parts and the sides thereof and flows into the back stream side of a heat transfer tube 13 whereby dead water areas 14a, 14b at the back stream side of the heat transfer tubes 13 are reduced remarkably and heat transfer performance may be improved. The boundary layer leading edge effect, the turbulent flow promoting effect and the dead water area reducing effect may be introduced and heat transfer rate may be improved markedly.

CONSTITUTION:BaCO3, Y2O3, and CuO are mixed in a specified ratio, and the mixture is charged into a water-cooled copper crucible 2 in a melting chamber 1. The chamber is evacuated to about 10<-3>Torr, and then gaseous Ar is introduced from an inert gas inlet valve 4 to control the pressure to about 350Torr. An arc 8 is then generated by a high-frequency igniter between a water-cooled tungsten electrode chip 7 at the tip of a water-cooled moving electrode 6 and the crucible 2, the initial current is controlled to about 150A and then increased to about 220A after the arc is generated, and the mixture is steadily melted for about 5min at the current density of 1-10A/g to obtain a molten metal 9. The arc is then extinguished, and the molten metal is cooled at the rate of >=5 deg.C/sec to obtain a button-shaped lump. The lump is crushed, press-formed, and then heat-treated at about 850 deg.C for about 5hr in an O2 atmosphere to produce the oxide-based or sulfide-based superconductor of about 90K class.
