摘要： A DC-DC voltage converter 40, which is adaptable to VHF operation, has a power oscillator 52 to which a filtered input DC voltage 50 is applied for conversion to an output DC voltage. The power oscillator includes a push-pull amplifier 58, 60 and an impedance transformation circuit 62 to which the amplifier is connected. The power oscillator also includes a rectifier circuit 64 which is connected to the impedance transformation circuit. A feedback circuit 68 controls the frequency of the oscillator to regulate the output DC voltage. The oscillator frequency depends on the impedance values of oscillator circuit components and the values of a plurality of oscillator component intrinsic parameters.

摘要： A cartridge for a magnetic disk drive has a clamping mechanism which is actuated as the door to the cartridge is closed when the cartridge is removed from the drive. The door covers the opening through which the cartridge is accessed by read/write heads. When the cartridge is removed from the drive, the mechanism of the present invention clamps the recording disk against the cartridge shell to prevent rattle, which might otherwise damage the recording disk.

摘要： A crush resistant cartridge case comprises a case shell having left and right halves. Each halve of the case shell contains a rigid insert having a flat portion with a rib extending substantially around the perimeter of the flat portion. The rigid inserts in the left and right halves of the case shell come together when the case shell is closed and provide resistance against crushing.

摘要： In a magnetic disk drive, a compliant member connects the top of the bearing assembly for the actuator arm to the drive. The member is compliant in the vertical direction and stiff in the horizontal direction to resist actuation forces being applied to the bearing assembly when the actuator rotates the arm. The actuator arm has a fork with a shelf on which the coil is mounted.

摘要： A cartridge for a magnetic disk drive has a rigid shell and a flexible door which covers an opening through which read/write heads engage the recording medium. The flexible door is guided outside of the shell to an open position as the cartridge is inserted into the drive. A projection on a flexible arm in the drive catches a hole in the flexible door to open it as the cartridge is inserted into the drive. The door which opens along the outside of the cartridge conserves space so that the recording medium can be large for a given form factor drive.

摘要： A high frequency, transformer capable of operating at high power levels is disclosed. Conductive ribbons including end (terminal) sections which permit the terminal leads of a plurality of windings to be extended from the windings in an overlapping relationship and in the selected order is utilized for the windings. Preferably, the core is formed of a material having low eddy current losses and characteristics permitting the core to be molded such that the windings are substantially surrounded by the core with the exception of small openings through which the leads extend.

摘要： Ski locking apparatus for attachment to a pair of skis arranged back-to-back comprises a pair of U-shaped body members each of which has parallel legs extending from a web. The legs of one member are shaped to embrace the legs of the other member. A latch bolt located between the legs of both members spans the distance between the webs and is secured at one of its ends to one of the webs and is anchored at its other end to the other of the webs.
