Title: Ni-zn ferrite and coil part using the same
Inventor: AKATA KAZUHIRO
IPC: H01F1/34
Filed: 1992-09-29
Abstract: PURPOSE:To enhance the temperature characteristics without deteriorating the characteristics such as initial permeability, Q value, etc., by a method wherein the proper amount of the compound of V2O5 and Bi2O3 is to be added to the Ni-Zn ferrite. CONSTITUTION:This Ni-Zn ferrite is produced by adding 1-5wt.% of V2O5 and 0.1-5wt.% of Bi2O3 to NiO, ZnO and Fe2O3 as the main components. Next, a coil 12 is formed in a magnetic element 11 comprising the Ni-Zn ferrite so as to manufacture the coil part. Through these procedures, the temperature coefficient can be minimized leaving the initial permiability, Q value and volume specific resistance intact thereby enabling the reliability upon the temperature fluctuation to be enhanced when applied to such coil part as a laminated inductor, LC compound part, etc.

Title: Duct active noise removing circuit and correcting method for noise removing signal
Inventor: DANIELS MARK A
IPC: F01N1/00
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To decrease distortion and to decrease group delay related to a loudspeaker by generating a voltage output proportional to a determined current and supplying a drive signal through a regulator means in response to a signal showing the speed of the coil while receiving this voltage output. SOLUTION: When an audio power amplifier 16 is started, a drive current is supplied to the coil of a speaker 10 by a circuit 12 and drives the loud- speaker so that a noise removing signal can be generated. The drive current is changed corresponding to the noise to be removed and a cone is moved corresponding to a speed change caused by noise to be removed. Therefore, the current to be supplied is changed by the amplifier 16. A voltage signal shows the direct measurement of current driving the loudspeaker and is achieved through a power resistor. A signal from a circuit 30 is supplied through the resistance of the voice coil coupling at the loud-speaker 10 and inductance to a compensation network showing a voltage drop.

Title: Reproduction-only optical disk and method for controlling its focusing and tracking
Inventor: UEDA TAKEHIKO
IPC: G11B7/24062
Filed: 1993-10-18
Abstract: PURPOSE:To improve the C/N by scattering light emitting layers which exhibit emission of light of the wavelength different from the wavelength of reading out light and expressing information with the presence or absence or length of information unit with the light emitting layers as the information unit. CONSTITUTION:The light emitting material of the light emitting layer 3a within a reading out light spot S makes transition from a base E0 state to an excited singlet E1 state and further transits to an excited state of a higher level En absorbing photons when the surface of a substrate 2 is irradiated with the reading out light B condensed to the diffraction threshold by a condenser lens 1. The distribution G2 of the excitation species of the light emitting material transiting to the high level En excited state at this time is expressed by the product of gauss distributions and the half width of the distribution decreases as shown in Fig. The light emission intensity from the light emitting layer 3a in this high level En excited state is detected by a detector 5 to obtain a feedback signal. The servo control of focusing is then executed by envelope detection in such a manner that, for example, the signal intensity is maximized. As a result, the light emitting layer comes to the central part of the spot S and the reading out light intensity in the spot S is maximized at this time.

Title: Bearing
Inventor: FUKUSHIMA HIROSHI
IPC: F16J15/43
Filed: 1989-10-05
Abstract: PURPOSE:To simplify a composition, prevent dust generation and lengthen a service life with extremely low torque by a method wherein a magnet is provided on a supporting member, a fixing radial bearing face is smaller in diameter than a large diameter face of a middle part, a non-magnetic shaft has a protrusion larger in diameter than the radial bearing face and magnetic fluid is interposed in a bearing. CONSTITUTION:When a protrusion 8 larger in diameter than radial bearing faces 5a, 5b provided on a shaft 3 moves to the right in a supporting member 1, since a pressure in the supporting member 1 is higher at both ends of an axial direction than a middle part, the protrusion 8 is pushed back to the left. Thus since the shaft 3 is supported by magnetic fluid 2, the protrusion 8 of the shaft 3 and the supporting member 1 are kept in no contact with each other. In addition, when the shaft 3 moves downward, the pressure of the magnetic fluid 2 in radial bearing slits 9a, 9b is higher at a lower section than at an upper section due to difference in flux density to push back the shaft 3 upward. Thus since the shaft 3 is supported in a radial direction by the magnetic fluid 2, the radial bearing faces 5a, 5b and radial receiving faces 7a, 7b are kept in no contact with each other.

Title: Synchronizing signal pulse generation circuit
Inventor: HASHIMOTO YASUNORI
IPC: H04N5/376
Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To provide a synchronizing signal pulse generation circuit for driving a solid-state image pickup element, which does not malfunctions even if the frequency of a reference clock pulse signal is high, suppresses whole consumption current and suppresses synchronous noise (FPN). SOLUTION: A counting circuit for counting the reference clock pulse signal is constituted by a Johnson counter where the D-type flip flops 1-8 of rise synchronous types are shift register-connected and the inverted output NQ of the D-type flip flop 8 in a final stage is fed back and connected to the D-type flip flop 1 in an initial stage. Thus, a state variable becomes uniform and synchronous noise (FPN) is suppressed. When the period of the reference clock pulse signal T>=tpd (CK→Q or CK→NA)+tSU (setup time) is satisfied, a normal operation is executed and therefore speed can be improved.
