Title: Optical pickup
Inventor: OGASAWARA MASAKAZU
IPC: G11B7/135
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To provide an optical pickup which can easily correct influences of astigmatism. SOLUTION: An optical pickup is equipped with at least a laser light source 1, an objective 5, and an aberration correcting means which makes aberration corrections by giving a phase difference to transmitted luminous flux, wherein the aberration correcting means corrects astigmatism originating from the optical system of the optical pickup. This aberration correcting means has an electrode for applying a voltage and a variable refractive index layer which varies its refractive index to transmitted light as the voltage changes, and also gives a phase difference for canceling the astigmatism to the transmitted luminous flux by controlling the voltage.

Title: Magnetic card
Inventor: ASUKE HISASHI
IPC: B42D15/10
Filed: 1990-03-28
Abstract: PURPOSE:To prevent the reading and writing error due to the adhesion of dust by adding a grinding material SiC to a protective layer within a specific ratio range with respect to the resin solid of the protective layer. CONSTITUTION:A magnetic recording layer 12 is provided on a base material 10. To the recording layer, that is, to the part between a magnetic recording medium and a protective layer being a top coat layer, a concealing layer and a magnetic bar code are laminated. The number of layers or the thickness of the layers is set according to the required output and required characteristics of a magnetic card but, herein, the layers are limited only to the concealing layer 14 and, finally, the protective layer 16 containing 20wt.% or less of a grinding material SiC is formed as the top coat layer. By this method, since the magnetic card can obtain a surface state wherein a cycle of unevenness is fine, the resistance to the magnetic recording reading and writing error due to the adhesion of dust caused by dirt from the hands or static electricity increases.

Title: Receiving device of electromagnetic induction power supply unit
Inventor: IKEGAMI SHINGO
IPC: H01F38/18
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To improve transmission efficiency on a receiving device and meet a fluctuation in load impedance on a receiving device, by switching the connection of a leader line with a diode bridge so that conductive efficiency may be optimum in accordance with the fluctuation of the load impedance. SOLUTION: A device is formed so that a circuit Q is made to be large when viewed from an induction field 1 by a receiving coil 2 and a serial resonance capacitor 5 meeting the coil, the Q value of a parallel resonance capacitor is determined by the L and R of the receiving coil 2, C of the resonance capacitor 5, the frequency of the induction field 1 and load impedance. If the load impedance is determined, the number of windings of the receiving coil 2 and the capacity of the resonance capacitor 5 can be determined so as to obtain the optimum Q value. Therefore, when the load impedance fluctuates, the number of the windings of the receiving coil 2 is set to be an optimum value by changing the location of a leader line according to the fluctuation. It is thus possible to transmit power with high efficiency by the induction power source for a load whose impedance fluctuates largely.
