Title: Conformal array antenna
Inventor: MAKINO SHIGERU
IPC: H01Q21/06
Filed: 1990-05-24
Abstract: PURPOSE:To improve the degree of freedom of the antenna design by taking a fixed point O onto a ground plate being a curved face, taking an orthogonal XY coordinate on a tangent plane at the fixed point O and arranging each element antenna on the surface of the ground plate being a cured face respectively at a point P at a distance (r) from the fixed point O on a geodestic line which is tangential to the plane in a direction theta with respect to the X axis while taking the fixed point as a start point. CONSTITUTION:At first, a fixed point O is taken onto a ground plate 1 being a cured face and an orthogonal XY coordinate is taken on a tangent plane 5 at the fixed point O. Then the fixed point O on the curved face ground plate 1 as a start point and a geodestic line 4 which is tangential to the direction tilted by an angle theta with respect to the X axis and to the direction tilted by an angle theta between a line O'P' and the X' axis shown in figure 2(a) is drawn from the start point. Then a point P at a distance (r) from the fixed point O on the geodestic line 4 is taken and the point is used as an arranged position of the element antenna 2. Similarly, the position P for all the element antennas 2 on the curved face ground plate is decided by repetitively mapping the position P' of each element antenna arranged at a prescribed period defined on the X'Y' plane onto the point of the curved face ground plate.

Title: Method for introducing carbon dioxide gas into water
Inventor: FURUBAYASHI YOSHIHIRO
IPC: C01B32/50
Filed: 1990-05-28
Abstract: PURPOSE:To prevent solidified carbon dioxide from evaporating and melting while it is sinking in water and keep it at the bottom of the sea in a deep region over a long term of years by cooling carbon dioxide gas produced at a thermal electric power plant, etc., to solidify it and covering it with thermal insulating fabrics. CONSTITUTION:CO2 produced from a thermal electric power plant is cooled to -80 deg.C to form it into solidified CO2 1 having a square pillar-like or spherical shape and its entire surface is covered with a thermal insulting fabric 2 such as thick wafer, jellied agar, natural fibers, wafers, etc. Preferably the fabric 2 has a proper elasticity and is easily soluble in water at the bottom of the sea and can be eaten by sea lives or is removed after a certain period of time. When CO2 1 is put into the sea at a depth of about 3000m or more, heat of the sea water is prevented from being transferred to the CO2 through the fabric 2 while the CO2 1 is sinking, and in a deep region of the sea, the CO2 1 is prevented from evaporating by the water pressure acting thereon, so that the CO2 1 dissolves into the sea water.

IPC: B41J2/175
Filed: 1989-05-29
Abstract: PURPOSE:To prevent ink leakage into a device even when a cartridge type ink vessel is used, and to supply a head safely with ink positively by installing the storage vessel of ink and a leading-out pipe leading out ink and inserting the external end section of the leading-out pipe to an elastic member for sealing, to which a rigid ring is fixed annularly.

Filed: 1990-05-25
Abstract: PURPOSE:To confirm the normal/defective state of soldered part by arranging a liquid crystal microcapsule having specified color transition temperature, on a circuit board and detecting a heat generation caused from high resistance of the defectively soldered part by its color transition. CONSTITUTION:The liquid crystal microcapsule (MC) 5 in the required quantity having specified color transition temperature, is supplied to the upper face side of circuit board 3.

When the rated current is applied 6 to the positions to be inspected on both sides of the board 3, heat is generated due to the high resistance value of defective joining part in the case the soldering joint is defective, and the MC 5 at this part changes color thereby the defectively soldered part is detected. If the defectively soldered part exists on the side where no MC 5 is provided, heat is generated also at this position, and the MC 5 at the reverse side changes color due to heat conduction through a printed circuit board 1, therefore, the defective soldering state at both sides of the board 3 can be ascertained at the same time.

IPC: H01J29/76
Filed: 1984-06-30
Abstract: PURPOSE:To enable misconvergence to be easily corrected independently of a convergence circuit by installing at least one auxiliary coil for supplying a correction current to a convergence corrector in a magnetic field formed by a deflection york and connecting the auxiliary coil to the convergence corrector. CONSTITUTION:Auxiliary coils 1 are installed in the window of a horizontal deflection york. They are connected to a convergence circuit which is installed on the back end of a deflection york separator and consists of a full-wave rectifying circuit 3, a variable resistance 4 and convergence coils 2. A voltage of horizontal periodicity is induced in the auxiliary coils 1 by a horizontal magnetic field and the thus induced voltage is supplied as a parabola-correcting current of horizontal periodicity through the full-wave rectifying circuit 3 and the variable resistance 4. The above parabola-correcting current produces a correction magnetic field which corrects X-axis longitudinal lateral-shift misconvergence. Consequently, misconvergence can be easily corrected by the correction current produced on the side of a cathode-ray tube.

Title: Nonaqueous electrolyte battery
Inventor: FURUKAWA SANEHIRO
IPC: H01M6/16
Filed: 1984-07-02
Abstract: PURPOSE:To improve high rate discharge characteristics by constructing a batter from a negative electrode having a light metal such as Li or Na or its alloy as the active material, a positive electrode, nonaqueous electrolyte composed of a solute and solvent, and by forming the solvent from the specified components. CONSTITUTION:A mixed solvent containing at least propylene carbonate and 1,2- dichloroethane is used as the solvent of the nonaqueous electrolyte. This type of mixed solvent dissociates solutes readily compared to other single or mixed solvents. Also, as the migration energy of the solute is reduced, the reaction between the ions of the negative electrode active material and those of the positive electrode active material is taken place smoothly. For example, the battery A manufactured using a mixed solvent containing propylene carbonate and 1,2- dichloroethane mixed in 1:1 ratio shows improved high rate discharge characteristics compared to the batteries B, C, D, containing propyelene carbonate alone, 1,2-dichloroethane alone, and propylene carbonate and 1,7-dimethoxyethane mixed in 1:1 ratio respectively.
