Title: Class c power amplifier
Inventor: TOKUZUMI NOBUYUKI
IPC: H03F3/68
Filed: 1989-05-30
Abstract: PURPOSE:To attain fine adjustment of power of an output signal while power loss is reduced by providing a power supply section supplying DC power selec tively to some of power amplifiers and an attenuator attenuating an output of a power coupler. CONSTITUTION:A control section 3 calculates which rank the power designated by a control signal takes, outputs a power on/off control signal in response to the rank to allow a power supply section 2 to select a power amplifier 5 being the object of a power supply and controls the power amplifier quntity so that the highest power is obtained in the rank selected while a power voltage control signal is outputted. Moreover, the control section 3 calculates a differ ence between the highest power of the rank designated by the control signal and the power designated by the control signal, generates an attenuation control signal depending on the difference to control the attenuation of the power atteuator 7. Thut, while the power loss by the power attenuator 7 is minimized, the power of the output signal is continuously varied.

Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To provide an electron emitting element by which stable emission electric current is obtained by decreasing the diameter of respective cathodes and the integration degree of the cathodes. SOLUTION: This element comprises cathodes 3 made of pole-like or needle- like conductive ceramics or conductive oxides projected approximately vertically on the surface of a substrate 1 and gate electrodes 5 installed near the tip end sides of the cathodes 3 and electrically insulated from the cathodes 3 and the element is so composed as to emit electrons out of the cathodes 3 by applying electric field between the cathodes 3 and the gate electrodes 5. Since the cathodes 3 are formed into a pole-like or needle-like shape by utilizing the etching speed difference in the grain parts and grain boundary parts composing the conductive oxide film of the cathodes, the diameter of respective cathodes 3 is easily narrowed and the degree of integration of the cathodes 3 is heightened. The diameter of the respective cathodes 3 is controlled to be several nanometer or several-tens nanometer.

Title: Disk revolving speed control method for optical disk drive
Inventor: YOSHIDA TORU
IPC: G11B7/005
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To provide a rotation control method effective for preventing a read error from being generated in the disk drive of a zone revolving speed control system performing revolving speed controls every zone like in a Z-CLV control system. SOLUTION: Whether data are continuous data or not is confirmed when a zone is to be changed (a step 20) and when the data are continuous data, a reading position is made so as to move a zone by reducing the gain of a disk motor rotation control system (steps 22 to 24) and, moreover, when the data are not continuous data, a seek is performed by increasing the gain of the disk motor rotation control system (steps 30 to 32). Thus, the read error in the reading operation of continuous data straddling over different zones is effectively prevented from being generated by properly changing over the gain of the disk motor rotation control system in the Z-CLV control system besides securing the stability and the followup ability of the revolving speed of disk which are to be required in an ordinary reading operation.
