Title: Tunable circuit board antenna and its tuning method
Inventor: JIYON EFU KENEDEI
IPC: H01Q9/04
Filed: 1994-10-03
Abstract: PURPOSE: To provide an antenna arranged on a circuit board where the necessity of individual parts such as a capacitor and an inductor is resolved and the resonance frequency of the antenna can be precisely controlled. CONSTITUTION: This antenna is arranged on a dielectric circuit board 10 and has a narrow and long conductive stub 14 having an end part 26 which is electrically connected to the conductive ground face through a through hole 16 plated with copper of the circuit board 10. The ground face, the stub 14, and the dielectric circuit board 10 are combined to form a resonance cavity 18. A through hole 14 of the circuit board 10 arranged in an end part 24 of the stub 14 opposite to the end part 26 connected to the reference ground face is selectively filled with solder or copper plating to electrically short-circuit the stub 14 to the ground face 12, and the inductance and the capacitance of the antenna cavity 18 are changed, thereby controlling the resonance frequency of the cavity 18.

Title: Optical pickup device
Inventor: HISHI TAKASHI
IPC: G11B7/08
Filed: 1989-09-14
Abstract: PURPOSE:To quicken the curing speed and to suppress the dispersion in the curing speed of an adhesives by packing the adhesives into a gap and forming the upper end of the gap wider than the lower part of the gap. CONSTITUTION:An adjustment plate 13 is positioned to an optical unit 15 at assembling in the order of 1 micron with respect to a prescribed position, and a prescribed amount of an adhesives is packed in gaps b, c between projections 15a, 15b and throughholes 13a, 13b with a discharge device. Moreover, an ultraviolet ray radiation device radiates a ray for a prescribed time with a prescribed luminous quantity to cure the adhesives to form adhesives parts 16a, 16b. Since the adhesives is packed to the gap between a notched part or a throughhole and a projection in this way, the dispersion in the coating quantity of the adhesives is kept small, and since the area of the gap is nearly equal, the dispersion in the curing speed due to the dispersion in the radiation UV ray is suppressed to a small value. Since the upper end of the gap is formed wider than the lower part, the UV (ultraviolet ray) receiving area is increased and the curing speed is quickened.

Title: Diagnostic method of deterioration of insulation of power cable
Inventor: SAKAMOTO ATARU
IPC: G01R31/02
Filed: 1989-09-14
Abstract: PURPOSE:To enable diagnosis of water tree deterioration of a main insulation of a power cable by impressing an AC voltage between the cable and a shield electrode, by changing an amplitude value of the AC voltage and by observing a change in a DC current component of a charge current accompanying the change in the amplitude value. CONSTITUTION:An amplitude Vo of an AC voltage impressed on a power cable C through a transformer T is increased from zero at a prescribed boosting speed, as indicated by a line J, by an autotransformer S. When the amplitude Vo reaches a prescribed value, it is maintained at this value for some time and then decreased at a prescribed step-down speed of the same absolute value. On the occasion, a DC component in a charge current of the cable C is recorded by an ammeter A. Then a current indicated by a line K flows when deterioration exists in the cable C. This current holds either a positive or negative polarity at the time of boosting and a polarity reverse to the above at the time of stepping-down when it flows. In the case when the water tree deterioration is serious, a current value observed in the ammeter A is large as indicated by a line L. By making an operation of boosting or stepping- down, accordingly, the presence or absence of the deterioration and the degree thereof can be diagnosed.
